Hay Feeding Strategies

Hay Feeding Strategies

 

Spring Hay Feeding

I wanted to send out a Timely Tips to encourage everyone to feed hay a little longer in the spring to let the grass get a good start. Spring grass is washy with high water content and some hay fed along with it helps to slow the rate of passage, improving digestibility. Also, allowing the grass to get a good start gives you a buffer of extra grass through the year. Typically, I will feed hay into early April.

 

One Location feeding.

The idea here is to reduce impacts on the pasture which is understandable but not a good plan for profit. The manure value is $20/1000 lb. roll of hay and the cost of reseeding an acre is less than $50/ac, so it’s ideal to feed hay on your most infertile ground. The manure is worth 10 x more than the cost of reseeding the small area impacted by feeding hay across a pasture.

 

 

Fenceline feeders are an improvement on one-location feeding because the tractor doesn’t have to enter the field, creating tracks and compacting it. However, it is still a method of one-site feeding, which has some downfalls.

 

 

If one hay feeding site is used, choose that site wisely. It should be 300’ or more from drainage ways and other water areas, away from sinks, ditches, and be on a slope of 5% or less. If feeding is done near sensitive areas, it’s potentially an environmental disaster and a contributor to poor water quality and disease. If animals spend their days in mud their energy needs are increased as much as 2x.

These areas need to be sown in something like bermudagrass or tall fescue to reduce weeds and take advantage of nutrients.

 

 

Accumulated waste should be gathered and ideally covered by a roof until it is spread on the land. If you have a pad, concrete is the easiest to scrape.  If using a gravel pad, you should leave a couple of inches of manure on the pad to keep from scraping up gravel and spreading it on fields. Since the cost of spreading usually equals the value of the manure, isn’t a great value at this point and we call it waste. Since most of the nitrogen comes from the urine, you’ll lose it to leaching if the manure is left in one place. 

Fall feeding:

I prefer to feed hay in the fall when I can grow grass this allows me to feed much less hay. It is possible to grow as much as five times the grass then hay fed in the fall but there are many variables to consider.

Decent soil fertility and properly managed grazing heights will grow more grass. Fall hay feeding can dramatically improve fields with weed problems and low fertility.  Ideally, allow sacrifice areas substantial recovery time before winter and you’ll see quick green-ups.

The minimum recommended grazing height for cool-season grasses, such as tall fescue, is 4” during the growing season. I don’t like to see it taken below 2” in the winter.

Bale Grazing.   There are many different ways to do bale grazing. It’s important to place the bales in the field when the soil is dry or frozen and place the bales strategically to accomplish the desired nutrient distribution.  The cows will cycle 80 to 90 percent of the hay back onto the pasture as nutrients therefore, if you want to increase fertility, you may want to place the rolls as close together as 30’ apart, which is equivalent to 24 tons of hay biomass/ac. If you are looking to maintain fertility, place the rolls approximately 80’ apart which equals about 3.5 tons of hay/ac.

 Ideally, stockpiled grass would be available along with hay which would be rationed with a temporary wire fence like polywire. You would paddock off an estimated amount of hay needed for 3 days or less. Example: 30 cows weighing 1200 pounds x 0.03 (percent of body wt. consumed per day) x 3 days = 3240 pounds. So, provide them access to 3 rolls. If the available grass is substantial, reduce the quantity of hay accordingly. Good grass is typically about 300 lb/acre inch.  However, only approximately 50% is consumed. Example: 8” grass x 300 lb/ac. In. x 0.50 (grazing efficiency) = 1200 lb, so reduce hay feeding by about one roll/day for every acre of grazing when available grass is substantial.

Hay can be placed behind a high hot wire providing calves or other stock the ability to forward-graze to more or better hay.

The biggest advantage to bale grazing is labor savings over unrolling hay.

 

 

Unrolling hay. I like this method best but to do it right, it’s labor-intensive. It really should be done once or twice a day, unrolling half of the animals’ needs in the morning and the other half in the afternoon to simulate grazing. They need to clean up most of the hay before feeding again. All hay isn’t equal so don’t make them clean up junk hay. 

One big advantage to unrolling hay is that all animals are on a more equal playing field, everyone having more access to hay. Hay rings can limit access and animals at the bottom of the pecking order, like young calves and sheep, won’t have equal access to the hay in a ring. Unrolling hay has great strategic manure placement.

Feeding in rings versus not using rings.  This may be controversial but there’s no doubt that although rings will conserve hay, the mud-out is much worse with a ring than without it.  My experience is if you have enough stock to clean up the hay in a day or less the hay waste is minimal but if the hay is there for multiple days a ring is going to be your best bet.    

 

Supplemental hay feeding square bales on a fence line flaking them out will allow all stock to get a bite of high-quality hay.

 

Remember, grazing is half the cost of hay. If you feed 3- 1000 lb rolls a day and hay cost is $40/roll, every day you graze instead of feeding hay will save you $120 since the nutrients (N-P-K) in those three rolls are worth about $60.

The next Timely Tips will cover different grazing strategies.

Frost Seeding Legumes

Frost Seeding Legumes

When it comes to frost seeding, all you need is a good honeycomb freeze (a shown in the above photo) and an electric seeder on a 4-wheeler. This cold snap we’re experiencing is a perfect time for frost seeding.  A layer of snow will help you to see your tracks and seed distribution. 

There are times when frost seeding might not be necessary.  If you maintained thick residual (intact plants 2” or taller) and residue (detached cover, mulch) all the pasture usually needs is recovery time. Also, if you are a top third grazer it’s going to be hard to maintain legumes due to shading them out, so why seed them? 

What fields should be seeded? Fields that have some exposed soil are the best candidates for frost seeding.  If you plan on feeding hay in those pastures this winter, just wait until March to reduce excess trampling. Unrolling hay can be beneficial after seeding as long as it doesn’t cause serious mud outs.

Frost seeding round seeds like legumes and brassicas works well with this treatment. Their shape and weight pull them into the ground for good contact and better germination.  I typically add 5 pounds of grass seed with the legumes and brassicas in order to thicken the stand.

What should you frost seed? Consider your existing fertility when deciding which species to seed.  The standard recommendation is “2,4,8 let’s renovate” coined by the late Dr. Joe Burns, University of TN Forage Specialist. That translates to 2 pounds of white clover, 4 pounds of red clover, and 8 pounds of annual lespedeza.  Ideally, your soil should have a pH of 6.2 or higher at seeding and have a moderate to high level of Phosphorus and Potassium.

Matching seeds with conditions will save time and money so it’s important to understand what each type of plant needs in order to thrive.

All white clovers, with the exception of the lower growing shouldn’t be sown unless fertility is high. 

When it comes to deciding what varieties to plant, I like to look at variety trials and compare them to see what will work best in each situation.  Typically, you won’t find big differences between varieties but how you manage your grazing heights and recovery times have the greatest influence on production and longevity.

 

White Clover: The larger leaf and upright habit of the Ladino white clovers make them good forage types.  Although Dutch types tend towards a more prostrate plant, these long-lived varieties tend to produce a lower yield. They are also better adapted to lower fertility then other white clovers.  Intermediate types like Patriot, Durana, and Resolute fall somewhere in between Dutch and Ladino types and are more aggressive.

A bermudagrass/legume mix makes a good stand when seeded into the bermudagrass in the fall, about 20 days prior to the predicted killing frost.

Red clover, a biennial typically lasting two winters can produce an extra year of production when sown in February or drilled in March.  Certified Red Clover seed can last three winters and allowing some seed set in the summer will increase the longevity of the stand by reseeding. Some varieties I seed are: Certified Kenland, Cinnamon, or 401RC.

 

 

Annual lespedeza is very well adapted to low fertility, low producing, and shady fields. If given ample recovery time in early September, this annual will reseed. Kobe is preferred for pastures and Korean for hay but the two are typically found in a mix.  Marion is one well known variety that tends to reseed better than other varieties.  The price of lespedeza varies widely from year to year so I’ll usually seed less per acre or won’t seed it at all if it’s higher than $1.50 per pound. 

Brassicas are annuals and good indicator plants.  They perform best where organic matter and soil fertility is good. Yellowing and poor performance are telltale signs of poor soil fertility.  Brassicas are often sown in the fall but a spring seeding can work very well with good survival through next spring.

Forage radishes are best known for their long tap root and for reducing the effects of compaction. Both tap and fibrous roots help to reduce compaction which usually occurs at  three to five inches. Longer recovery periods increase roots and decrease compaction. Tillage exacerbates compaction issues.

Forage radishes and turnips are best seeded at less than 2 lbs/ac.  I typically seed one pound per acre

Spring pugging (hoof imprints in the field) benefits from a seeding of a grass/legume mixture.  KY 31 contains endophytes and reduces animal performance but it’s a tough grass that holds up better to traffic and short grazing.

For years, I have seeded improved grasses along with legumes and brassicas on my hay feeding areas but I have concluded that especially where hay rolls have been set across the fields, KY 31 is the best choice. I have found that no matter what grass is seeded, the livestock graze the tender new seedlings more than well-established grasses and KY 31 can hold up better.

Orchardgrass and Persister bromegrass are tolerant of shading and do well in mixes. A good stand of annual ryegrass is almost guaranteed but can be very competitive with legumes and perennial grasses.  I don’t recommend adding more than 1 lb per acre. I usually recommend adding spring oats at a rate of less than 20 lb/ac with the legumes.

If seeding in March, it’s best to use a no-till drill or light tillage to get seed soil contact.  A cultipacker behind the seeding is ideal. Another option is to wait till May and seed a warm season annual like Sudangrass on feeding areas.

All that said, if cost is an issue, seed lower rates, half rates work well if you have good seeding conditions.  I do not like to spend more than $35/acre on seed.

Cost effectiveness: The clover should produce fifty or more pounds of Nitrogen/ac. At $0.40/lb of N an annual return of $20 is typical and if your stand lasts three years, that’s $60/ac.

Why Should you invest in Frost Seeding?

Animal gains per acre should increase easily by 0.2 lb/day or $45/ cow/calf per year. Milk production, body condition. and conception rates should also improve.  So, a conservative return is $65 per acre/yr plus increased conception rates and improved soil health.

Management of legume seeding

It’s best to not fertilize with nitrogen the same season that legumes are seeded as it stimulates grass growth, thereby shading out the legumes. If phosphorus is low, it’s best to use something like a low N 11-52-0 (MAP).  Keeping light to the newly seeded legumes will be important for survival rates.  Managed grazing and/or clipping will endure a good stand.

The Evolution of a Multi-Species Grazing Operation

The Evolution of a Multi-Species Grazing Operation

The Goal of Big Spring Farm:

 “An easily managed, low input grazing operation that improves production and the environment while being consistently profitable” Greg Brann.

 

Brief History of Big Spring Farm 2005:  The Big Spring Farm is named for a boiling cold spring that is estimated to have an output of 30,000 gallons per minute.  The farm was purchased by my dad in 1964 for cow-calf and trout production, unfortunately, the trout enterprise never materialized.  The farm increased in size due to land purchases and land rentals to 1200+ acres of pasture and hay.  Over the years, tobacco, Christmas trees, corn, and soybeans have all been produced but it has always been predominantly a cow-calf operation.  The largest number of cattle was 300+ cows and 270 backgrounding stocker calves.  Dads’ famous sayings were “good pasture is the best fence” and “don’t fix it too good they can’t get back in” and while he did pretty well at maintaining some single wire electric cross fence, the perimeter fence steadily rusted away.  At 88,  my brother and I are slowly taking over the running of the operation.  Currently, my brother and I have divided up the operation and entered some land in CREP, a state form of CRP, leaving my operation with 210 acres of pasture.

 

Fencing: My brother and I decided we had to have a good perimeter fence above all so that became a priority.  With all the blackberry briars, buckbrush, and assorted browse, goats seemed to be a choice species for us.  Since we always preferred high tensile fence, what is the big deal about adding an extra wire or two to run goats too?  We didn’t know much about goats but I knew it was accepted knowledge that a producer can run 1-2 goats for every cow and not impact the cows grazing.  Later we found it actually improved grazing for the cattle.  After about one year my brother decided he had had enough of goats dying (Listeria and various other adaptation disorders) and wrestling to de-worm them and trim feet, so I bought him out and continued the goat enterprise.  Thankfully, he didn’t charge me any rent since he knew that running them on the correct pastures would control weeds.  Later we divided up the land and now he and his sons run stocker cattle and I run a multi-species grazing operation. 

With any new enterprise, you go through an adaptation trough phase for 3 to 5 years before you reach a new plateau for the enterprise.  Initially, we just fenced the perimeter of one area and used electro-net fencing to control graze about an acre at a time with a stock density of 7,000 lb/ac.  This worked pretty well.  We would set up two paddocks at a time and when they moved into the second paddock we would move three sides of the first paddock and set up a third paddock hopscotching across the field.  Other areas we fenced were the boundary of fields allowing the goats access to the whole field while cattle were control-grazed.

The ideal fence and water layout are parallel fences about 435’ apart with water hookups located 435’ apart in every other fence line.  This allows maximum flexibility.  I like 435’ because a 100’ length equals one acre.  Three rolls of electro-net 164’ each will more than span this width and if you are using single polywire with a post spacing of 40’ you can easily carry 8 to 10 posts.  When I run a high single polywire for cattle (48” high) I space post up to 100’ apart.  In the end, when terrain, woods, soil type, and vegetation are all considered spacing between parallel fences may need to vary considerably. Any distance you are willing to walk and install temporary fence is just fine.  Initially, you may want to install every other fence with the ultimate goal of installing others later.  Not every fence needs to be worthy of controlling all species.  When wire is closer to the ground try to target 7” with post spacing needs to be closer usually 40’ works even in rolling terrain.  In one year, counting all of the temporary fences built, we have over 50 paddocks.

Creep grazing: Now we run one herd consisting of cows, calves, sheep, lambs, does, kids, a donkey, and five guardian dogs.  It’s rather entertaining to watch the herd dynamics. I have eleven permanent paddocks to control all animals and we run a high single polywire holding the cows back and allowing the calves, sheep, and goats to creep graze, and in winter creep hay.  This allows creeped animal’s access to more choice thereby increasing nutrition.  At other times, I run another low polywire which restricts calves and allowing sheep and goat to graze.  This is only necessary when sheep and goats need higher nutrition, such as at breeding or birthing time.  It’s also used to keep cows and calves out of sericea hay or high dollar sheep mineral.

Goats to Sheep:  Compared to cattle, goats are quite inexpensive, and improving genetics is more difficult when the initial cost of the animal is higher and the gestation period is longer.

Once you are fenced for goats you can run pretty much any species.  I monitor forage and pressure continuously for recovery needed to improve forage management.  So, I constantly adjust the number of cattle, sheep, and goats relative to what is best for the pasture and animals.    Goat numbers at Big Spring Farm fluctuated from 70 to 300 back down to 70, up to 130, and has now settled at around  50 does (Kiko/Spanish nannies).  My reasoning for the downsizing is that, even though the goats are extremely prolific and easy to keep, I found the goats compete with the sheep (Katahdin) for forage.  

In my experience, sheep compete more with cattle for forage but they are also more productive than goats and cattle and easier to handle. The bottom line for me is that adult ewes over one-year-old rarely need deworming, Katahdin sheep can be bred at 10 months of age and have lambs unassisted after just five months of gestation.  Sheep have a higher twining percentage of 1.7 lambs per ewe, whereas the goats only average 1.4 kids per doe. I’ve found that sheep typically don’t eat much hay till all the grazing is over, which is a good thing, but, be careful, they will overgraze if not rotated often.

Cattle to sheep:  I’ve been decreasing the cow herd since I’ve found sheep to be so much more productive per female.  I don’t know of any other animal that can wean more than their weight in 10 months.  Cattle are doing well if they wean 45% of their weight but sheep will wean 100% or more of their weight.  The sheep and goats naturally wean their lambs, which creates much less stress for me and the animals.  In the past, we had the most problems during weaning lambs and kids. Most of the issues have disappeared now that we allow them to self-wean, eliminating stress for us all.  If I was lambing more frequently  I would certainly need to wean to maintain ewe condition.   If I have one ewe that doesn’t maintain condition due to longer lactation I will likely cull her since she doesn’t fit the herd management.

Due to the stress involved, I am trying to not wean calves either but since cattle lactate longer it makes it much harder. We are selecting for natural weaning cows but still wanting to see the calf weigh at least 45% or more of the cow’s weight when it is ten months of age.

One group versus separate groups: Although I  have run the goats and sheep together without incident, I’ve resisted combining the sheep with the cattle due to the inconclusive information regarding the tolerance of Katahdin sheep to copper.  After visiting with several sheep producers who have fed beef mineral to Katahdin sheep for 5 years or more I decided to take the chance.  It is important to note that wool sheep seem to be more sensitive to copper toxicity than hair sheep.

One huge advantage of running separate groups is you can target graze certain plants.  However, the benefits of running one group far outweigh the advantage of target grazing.  Target grazing can still be done but you must consider the impact on other animals in the herd. Some call it a flerd; part flock, part herd. 

Longer rest periods for pasture (which reduces internal parasite load), being able to feed guardian dogs at one location, hay feeding in one location, more power on less fence,  less fence to check, higher stock density for shorter periods of time are all benefits of the flerd system.

Separate herds: In the past, I always maintained a “sell lot” for anything that was not performing up to the standard of the herd.  Since we don’t want any births occurring in mid-December through mid-February the rams and bucks are pulled July 24 through September 24. Bulls are just left in with the herd and I  pregnancy test in November or December and sell all cows not bred or bred out of sync with the group.  The target is a 60 day calving period.   Calves are kept till 24 months old and sold as grass-finished cattle. Heifers that don’t breed are still worth a premium as finished cattle.  

Watering Facilities: Water is the most important nutrient and is a major draw for the location of cattle.  Sheep and goats don’t tend to hang around water the same as cattle do.  The tendency is for the pasture around the water point to be overgrazed, partially due to allowing back grazing for more than 4 days. 

 I am a big believer in a pressurized water system so that you can place the water point where you want it and not be dependent on a good pond site, gravity flow,  spring flow, or limitations of ram pump, solar pump, etc.  The ideal spot for a water trough is based on rotation, forages, and lay of the land.  In general, I want the watering point to be located on a slight slope of 3% grade near the ridge top but mainly you want your to have water throughout the property so that no water point is overgrazed 

I have ball waters, ( Richie and Mirofount), tire troughs, open goat troughs, rubber maid portable troughs, and old protein tubes plumbed.  I prefer the Gallagher brass valve for open troughs.  I like the Mirofount more than the Richie for cattle due to the visibility of balls and the option to take off covers with plumbing still covered. However, the balls are harder to push down on the Miirafount.  Balls in either trough can be taken out.  Goats and sheep don’t have the power to push balls down like cattle.  The ball troughs are lower maintenance than other troughs but more expensive.  I mainly have tire troughs throughout the farm.  They’re great for big herds but I have lost several goat kids and lambs in the open troughs due to not having the water level high enough.  The water must be within 2” of the top.  You’ll need to place blocks in water deeper than 12”. 

Forage: In general I believe in managing the forage you have and not completely reseeding the entire pasture.  A good start is taking a soil test to know the status of soil fertility.  If fertilizer dollars are limited, apply lime and fertilizer to low testing soils first.  Also, consider the most potential is productions on the best soil types. Get a soil map from the USDA/NRCS office or www.websoilsurvey.com.  

When it comes to seeding mixtures, there are so many choices; cool and warm season, annuals and perennials, grasses, legumes, brassicas, and other forbs and browse.  Ultimately its good to have about 30% of the acreage in warm-season forage.  First evaluate if your stand of grass is adequate, for cools season grass you need a plant every 6” with 3 strong tillers.  If you don’t have this you will need to seed grass as well with a no-till drill or some tillage.  The easiest and cheapest way to upgrade the pasture is by adding legumes through frost seeding.  There are many advantages to having legumes: higher quality forage, provide nitrogen, lengthening of the growing season.  The negative aspects of legumes of over 35% are that it can create voids in a drought.  Although white clover is the cheapest, only costing 7-$10/ac to seed at 2 lb/ac  I would recommend seeding 4 to 7 lb of red clover/ac. On the most droughty land seed annual lespedeza 8 or more lbs per ac. Lespedeza has concentrated tannins in them and are natural dewormers.   Annual crabgrass is an annual that can fill these voids, providing warm-season forage. Crabgrass is a reseeding annual that is a savior but the negative side is it needs disturbance from tillage or high animal traffic at least once a year to maintain vibrancy.   Native grasses have great potential but they are slow to establish (approximately 2 years) and do not tolerate close grazing.  Bermudagrass is not preferred forage of goats but is excellent around heavy use areas such as corrals or water points.  Common bermudagrass spreads by seed, rhizomes, and stolons so it spreads more than hybrid types that very few viable seeds, making the hybrid types vegetatively preferable.   Another thing to consider in the evaluation of fields is certain plants that increase due to avoidance by livestock so they are left to reach their full expression and make seed while other plants decrease due to overgrazing and excessive use.  Putting pressure on plants you want to decrease especially when emerging and when they make seed are major tools to use to improve pastures while resting or allowing full recovery of plants you want to increase can bring change your pastures quickly.

Hay: Buying hay is always a good deal since the cost of making hay is so high.  The average cost of making hay is $80/ton.  Also when you bring hay onto your farm you are bringing in nutrients.  Each ton of hay, on average, contains 45 lb N, 12 lb P2O5, and 45 lb K2O or $50/ton in nutrients.  The key is getting those nutrients deposited by the livestock well distributed over the field.  When manure is deposited in the barn, rather than directly on the pastures, the expense of equipment, time, and fuel to load and spread the manure change the economics drastically.  Also, remember that when nutrients end up near water they can cause water quality issues.

Summary:  Every time I enter a field I evaluate the impacts and improvements of management and determine what is needed to improve the economics, environment, and community dynamics of the operation.  Mostly, working with nature is rewarding and humbling.

Fencing for Serious Graziers

Fencing for Serious Graziers

Electric fencing offers two major advantages over other types of fencing. One is cost. The cost to install a four-strand, barbed-wire fence is about $5,000 per mile. The cost to install a typical, single-wire, electric fence is about $1,600 per mile. If necessary, additional wires can be added to an electric-fence for about 10 cents per foot. The other big advantage of electric fencing is its ease of construction, which improves forage management opportunities. Small pastures can greatly enhance harvest efficiency and increase the amount of forage produced from a grazing system because of the amount of rest that is introduced into the system.

Water Points

Water Points

Water the most important nutrient! It’s the largest quantity requirement for beef and dairy cattle (e.g. 15 gal/day = 125 lb/day). Water is commonly the weakest link in grazing systems. Water placement impacts grazing (overgrazing and under utilization) and nutrient (manure and urine) distribution.  If you have excessive trailing is a sign of needing better water distribution.

Timely Tips – June

Timely Tips – June

We are at the change of seasons.  A time to contemplate and plan for summer forage. Note in the graph above, as temperatures hit 80 degrees F. or higher cool season forage production decreases and warm seasons forages kick in high gear.  I encourage you to make warm season and drought management decisions prior to the end of the recommended seeding date for warm season forages, July 1.

 Options:

  • Stockpile cool season forage into summer
  • Graze a field hard to release the seed bank for natural regeneration
  • Seed summer annuals
  • Seed summer perennials
  • Fertilization to improve warm season production

Stockpile cool season forage into summer. 

Although I think it is wise to carry some cool season growth into summer, the quality of it will be dependent on temperature and rainfall.  It may hold all summer but if it gets hot and dry it will just be some carbon to lay down and forage quality will be very poor.  Red clover and annual lespedeza will extend growth into summer.

Graze a field hard to release the seed bank for natural regeneration

It’s a lot like rolling the dice.  Unless you know the field well you may release some warm season species you don’t want. This technique works extremely well for release of bermudagrass, crabgrass and dallisgrass.  Other plants that are also likely to grow white clover (if it is cool and moist), ragweed, lambsquarter (both test like alfalfa but stock don’t always consume them), spiny amaranth (weed due to spines other amaranths are palatable and high quality), cocklebur (bad weed, big canopy, sometimes consumed), nimblewill (terrible grass weed that looks like bermudagrass, not readily grazed). Grazing 20% of the pastures low May –June is a decent strategy.

Seed summer annuals. 

Crabgrass, cowpeas and lablab are the only species that UT recommend planting as late as July 1.  Forage & Field Crop Seeding Guide For Tennessee

Crabgrass Improved Variety Options Crabgrass improved variety options:

Quick and Big and Red River.

Quick and Big is fast growth and Red River has a longer growing season.  You may want to seed a blend of the two, sometimes folks add annual lespedeza to the mix.

The seeding rate of crabgrass is 3 to 5 lb/ac.  If you add annual lespedeza 8 to 10 lb/ac.  Crabgrass is a reseeding annual that responds to disturbance at least once a year.  Cowpeas, high quality drought tolerant legume which makes a good smother crop if you have an undesirable weed you are trying to control.  Even though it is a little late for millet you may want to add 10-20 lb/ac. of pearl or browntop millet with the cowpeas.  Lablab is typically grown for wildlife food plots but is good forage for ruminants too best used in a mix.

 

Seed summer perennials

Bermudagrass is the only plant UT recommends planting as late as July 1.  I usually just recommend bermudagrass on areas that are planned for heavy use areas or where nutrients are going to be high.  Bermudagrass has some issues, stem maggot (it kills the primary stem tip reducing production) which most spray an insecticide for control, grazing could be used to reduce impacts also bermudagrass does best where nutrients are high.  There are several improved bermudagrass varieties: Cheyenne II (highest producing seeded type); Laredo (Allied seed variety, blend of Mohawk , KF-194, & Rancher; Wrangler (most cold tolerant).  You can also establish bermudagrass with clippings using Vaughn’s No. 1 which is typically thought of as the Cadillac of bermudagrasses for our area. Bermudagrass can produce high tonnage, be used hard and overseeded with clovers and winter annuals the second year after establishment.

Another warm season grass option although it is too late to seed now is native warm season grass (NWSG) it’s best sown when seed are exposed to a couple of cold chills (vernalization). Now is the time to start planning for it.  I like NWSG sown on lower fertility soils so weed competition is less. On low production you are not giving up much production while the natives are establishing for a couple of years. Usually herbicides are used to establish NWSG however an option to establish it without herbicides would be to terminate existing vegetation with tillage plant a summer annual leaving most of the biomass on the soil surface then no-tilling in cereal rye.  Dormant planting NWSG in December – April into cereal rye.  Rolling down the cereal rye in early April for weed control.  Natives will emerge through the residue in the spring.

Fertilization to improve warm season production

Applying nutrients to grass May – July increases warm season production.  Nitrogen has the biggest impact on forage production, nitrogen also increases protein content in the grass.  Typically no more than 60 lb of nitrogen is recommended in one application and typically applications should be scheduled 30 or more days apart. I personally don’t like over 45 lb of nitrogen in one application because if it turns off dry, high rates of nitrogen can cause forage to accumulate nitrates.

Grazing Annual Cover Crops

Grazing Annual Cover Crops

“Can we graze cover crops?”  The answer is yes, with an “it depends” attached.  It depends on soil conditions, the growth stage of the cover cro,; the reason you planted cover crops, and whether you’re involved in a conservation plan or program that requires other criteria.  Annual cover crops can be utilized quite well by grazing livestock, and they can also be part of a cropping system that can enhance the soil resource, but if grazed then it has to be managed correctly.

The nutritional values of most cover crops will meet the needs of most grazing livestock.  The ability to utilize annuals with grazing livestock allows longer rests periods for pastures, and also the ability to grow more forage, and graze longer reducing the amount of fed feed. Utilizing livestock on a cropland field can also be advantageous for increasing biological activity because of all the added flora of the rumen.  The majority of the nutrients that run through a ruminant animal are placed right back onto the ground from where they came.  The grazing of slightly more mature material mixed with a lower carbon to nitrogen (C:N) ratio species can help increase soil organic matter and get the nutrients in a more available form for the next crop.

These reasons can be positive as long as the primary purpose of the cover crop is not compromised.  Grazing must not cause any additional compaction problems, erosion, and/or rutting, and there must be adequate live plant material left behind.  This live plant residual is needed for adequate growth for the primary purpose(s) of the cover crop such as adequate cover for erosion control, winter survival, and adequate leaf area available for termination; sufficient root growth to reduce compaction and recycle nutrients; etc.

Dry or frozen soils are the ideal conditions to graze cover crops.  The livestock should not be grazing the cover crop under wet soil conditions unless a large amount (>2 tons/acre) of mature vegetation is present.  These larger amounts are normally only accomplished from a summer planting.  The key here is to not increase compaction…at all…nor to cause pugging that will cause erosion or hinder no-till planting of the cash crop next spring.

The cover crops also need adequate growth available before any grazing is initiated.  The start grazing height will vary some according to the species, but generally you want a minimum of eight (8) inches of growth for most species and rarely do you want to graze it down any lower than four (4) inches.  Maintaining adequate live plant residual is critical in keeping the plant growing and serving the intended primary purpose.

Livestock should not be left in any one area for a very long period.  Ideally, livestock should be moved or allocated new forage every 1-2 days.  Larger allotments can be utilized, but expect slightly less efficiency.  Livestock can remove vegetation very fast; keep a keen eye on the cover crops to make sure they are not overgrazed.  The cover crop should be checked every day, whether moving the livestock or not.

The best utilization and control is achieved by strip grazing annual cover crops.  Strip grazing is allocating out a set amount of forage that you know will meet the needs of the livestock for a set time frame and still maintain the required live plant residual after removing the livestock.  This can be achieved with reels of poly-wire and step-in posts.  Generally you will want three sets (reel and sufficient posts) for the front fence, the back fence, and the fence of the next move.

If grazing highly digestible forages add some roughage to slow the passage through their rumen enabling them to absorb nutrients.  The best solution is to not select only highly digestible, high nitrogen forages for a cover crop when they may be grazed.  These highly digestible forages move quite quickly through the livestock’s digestive system when grazed alone.  Planting a mix of forages that will provide both fiber and protein in balance is ideal.  An example could be mixing a warm season annual grass with a brassica in late summer to be grazed later that fall or early winter after the warm season grass has dried off.  Grazing cover crops in the early reproductive stage is the best way to slow the rate of passage through the animal.  You can also feed some hay or soyhulls to slow down the rate of passage.

Water should be provided to the grazing livestock and moved on a regular basis to keep them from spending too much time in any one area.  Portable tanks and water lines are a good way to do this.  Having hydrants or quick couplers located along one side of the field will allow multiple connecting sites.

It is rare to have good soil conditions for grazing throughout the entire fall, winter, and early spring.  Generally, do not leave livestock on the field all winter long.  They should be moved off the site if soil conditions dictate the need to prevent degradation, even if there is available forage still present.  Have a plan to move the livestock off of the field during wet periods, such as moving them to a perennial pasture or sacrifice lot, until ground conditions are okay to continue grazing.  Do not feed the livestock any feed or hay out on the cropland field to prevent excessive gathering and trampling.  Overused sites will become compacted!

Summer idle ground could also be planted to an annual cover crop mix, then grazed either during the growing period, or stockpiled for fall or winter use.

A cover crop mix to consider for grazing and soil health is:

Species                               Pounds/AC       

               Cereal Rye                         40

               Wheat                                 26

               Crimson Clover                 4

               Turnips                               1

               Radish                                 2

                                                            73

The rate of wheat could be increased to as much as 100 lb/ac.  If you are real adventurous you can add a couple of pounds of buckwheat and one pound of sunflowers. The buckwheat and sunflowers will freeze out at first frost.  Perennials properly managed build soil better and more cost effectively than annuals it is typically only recommended to seed annuals in fields with less than 50% desirable stand of cool season perennials like tall fescue because money spent on fertilizer instead of seed would yield more return.  The best pasture to drill cool season annuals in is warm season pastures like bermudagrass, crabgrass, dallisgrass and johnsongrass pastures.
