Here’s a primer for managed grazing, Part III

A few more thoughts on grass regrowth, animal production and timing.

In the first two stories of this series we covered some terms used in managed grazing, provided their definitions, and explained why the terminology and the ideas they represent matter.

In this third and final article of our managed grazing primer, we’ll cover some important concepts that aren’t based in terminology.

Plants: Taller and deeper is better

Early in the days of managed grazing there was a huge and largely mistaken emphasis on grazing plants in Phase II, or vegetative state.

Pushed to its logical end, this resulted in what then grazing consultant Burt Smith once commented about New Zealanders: “They’re so afraid of Phase III growth they never let their plants get out of Phase I.”

Young forage is high in nitrogen/protein and low in energy, while older forage is higher in energy and better balanced in a ratio of nitrogen/protein, although it has higher indigestible content.

This older attitude foiled the greatest advantages of managed grazing. It never let the plants work with soil life to build soil. It never let the grazier build much forage reserve for winter or for drought.

Last but not least, we were told for years the quality of taller, older forages was so poor that cattle could not perform on it. That is not necessarily true of properly managed, multi-species pasture where soil health is on an increasing plane and cattle are harvesting forage for themselves. It’s all in the management.

Balance animal needs with grass management

One of the most important concepts to managing livestock well on forage is to recognize livestock production and nutritional needs and graze accordingly.

If you have dry cows or are dry wintering cattle, you might ask them to eat more of the plants.

Remember the highest quality in mature, fully recovered forage is near the top of the plants and the outer parts of newer or longer leaves

Again depending on livestock class and forage conditions, an affordable and well-designed supplement program can let you graze more severely, also.

Erratic grazing breeds success

Nature is chaotic and constantly changing, so your grazing management needs to be also.

If you graze the same areas the same way and same time each year, you will develop plants you may not want because they will try to fill the voids you are creating and you may hurt plants you desire because they will become grazed down and weakened, perhaps at critical times.

If you move those grazing times and even change animal densities and perhaps also add other grazing species, you will create more diverse plant life and soil life.

Remember, too, that your livestock don’t need to eat everything in the pasture to do a good job grazing.

Cattle legs are for walking

Water is always a limiting factor for managed graziers, but the low-cost solution in many cases is to make cattle walk back to water.

Certainly you can eat up thousands of dollars of profit by installing excessive water systems and numerous permanent water points.

This can be overcome to some degree with temporary fencing back to water and using existing water sources.

Why is it so difficult to raise sheep?

This was the first question posed to me after my speaking engagement with Farm Service Agency personnel in Kansas City on July 15.  It was after the fact because it wasn’t pertinent to my purpose of being there and we had a limited time frame.  Too bad on that, great group of people who truly seemed interested in the ‘boots on the ground’ aspect of farming and ranching.

Now, if you raise sheep and it is not difficult for you, then that is great.  But my take on it is that they are far too time-consuming for my lifestyle choices and from a cost effective viewpoint.  So bear with me.  You can tell your story in your blog and I would like to read it!

Taking the emotion out and just putting economics to it:

Right now, the biggest economic advantage that sheep have over cattle or even goats, is the initial purchase price.  Consider that a young bred cow costs $2500-$2800 compared to 5 bred ewes costing a total of $900-$1125.  A cow will produce one calf ready to sell in about 10 months.  Five ewes can potentially have 10 lambs to sell, but realistically, more like 7 lambs and they can be sold at about 7 months.  Now, bearing in mind, that calves and lambs can be sold earlier or later, weaned and unweaned, etc, etc.  So, I will try to compare the two the most fairly as possible, but market and weather conditions can often dictate a different scenario.

A 10 month old steer calf with no creep and unweaned, on average comes off momma at about 450 lbs, a heifer maybe 400 lbs.  The steer, at auction at today’s prices, will bring $280/cwt or $1260 per head.  The heifer about $1008 per head.  Since the calf crop is typically 50% steers and 50% heifers, the average will be $1134.

A 50 lb lamb will bring about $1.75/lb and there is no differentiation between wethers and ewes.  The average then would be $87.50/head.  Better lambs should weigh 80 lbs at seven months, resulting in $980 total – but most likely, not all seven head will do that well.

SO:

Seven lambs to sell per year – $612.50-$980

One calf to sell per year – $1134

Costs:

Labor – significantly more with sheep.  They need nearly daily inspection since they tend towards getting caught in brush, fences, ditches, whatever, and need extracting.  If not found at least in 24 hours, they will die.  Even grown ewes can fall prey, resulting in not only the death of the ewe, but her unborn lambs or orphaning the ones she may already have.  This means more work for you if you can figure out which ones are hers.  You get to be mom for however long you keep them, including feeding them multiple times per day.  The best investment for that task for me is a lamb milk bar with seven nipples.

Infrastructure (fence, water) – unless you are willing to install permanent type woven wire paddock fencing (very expensive), then the next choice is flexible fencing with electrified netting.  Cost effective to purchase, but time consuming.

Consider:  100 ewes and their lambs will consume about 3% of their body weight (similar to cows), so assuming ewes weighing 180 lbs times 3% equals about 6 lbs of grass per day or 600 for the entire flock.  If your pasture offers 200 lbs of forage per inch of growth and you have 7 inches of growth and want to leave a 3 inch residual (to facilitate regrowth), then there is 4 inches times 200 lbs or 800 lbs forage on offer.  Say you only want to move them every three days, then they should have at least 3 acres.  To fence 3 acres in a square takes 1450 feet.  Electric nettings are 164 feet long, so you are moving 9 nettings every three days.  Don’t be fooled by the advertising that touts that it only takes 10 minutes per net.  No way.  I’m pretty darn fast at it now, but by the time, you pull the posts, fanfold them, roll them up, tie them, walk to the next location (or load them all up and drive them to the new location), unload (but first you have to untangle them from each other if you stacked them), walk them back out, then step them into the ground (if it’s not frozen or the ground isn’t hard that is).  So, for each netting, taken down and reinstalled, you’ve logged at least 656 feet, not counting if you’ve had to pack it a long distance before setting up again.  I’m going to give a general 20 minutes per net.  This doesn’t really allow much for when you have to hammer the feet of the posts into the ground or unhooking from snags, removing sticks, and just general untangling.

Nine nets times 20 minutes is 3 hours!  that’s every three days for only 100 sheep!  Compare the equivalent of cows and calves moving everything three days – about 30 minutes and that’s if you have to find baby calves that were left behind. The difference becomes even more significant when one considers that i can shift 250 cows and calves in maybe 45 minutes.  These times are taking into consideration strip grazing in winter and taking out hay as well as the easier moves in the spring, summer, and fall.  However, ramping up the number of sheep would incur significantly more netting and thus considerable more time.  A single strand semi-permanent hi-tensile electrified wire is cheap and easy to install and wiill easily contain cattle and once the fencing is installed, it requires very little time to shift mobs of 1000 or more!  Interior paddock division fencing that will actually contain sheep is definitely doable, but is considerably more expensive in materials and labor to install and maintain.

So to compare on a larger scale with 5 ewes equalling 1 cow.

250 cows with 80% calf crop – $226,800 income per year.  Shifting every three days or 122 times per year at 45 minutes each for a total of 91.5 hours per year.

1250 sheep with 140% lamb crop – $183,750 (60 lbs times $1.75/lb).  Shifting every three days or 122 times per year (this is used for comparison only – realistically, winter time will require set stocking and unrolling hay.  The netting spikes cannot be pushed into and pulled out of frozen ground).  If 100 ewes needed three acres, then 1250 need 38 acres.  Perimeter at 5146 ft divided by 164 ft is 32 nets times 20 minutes per net equals 10.7 hours per move times 122 shifts.  Hours spent annual moving fence and/or taking out hay is 1305 hours.

If you have better forage and soil health, paddock sizes could be much smaller, thereby reducing the amount of acreage needed for each shift which would subsequently require less netting.

Other considerations:

Sheep in north Missouri must have good fences and excellent guard animals to keep them alive.  Coyotes, foxes, eagles, dogs, etc nab them with abandon to feed their young.  Sheep also have accidents – but so do cattle – but sheep seem to have a better knack for it.

The death of a sheep is a far less loss of investment than a calf or cow.

Sheep and cattle facilities are different, but if planned in advance there is a good opportunity to use the same corrals.

Some people do get along without netting.  From visiting with them, they raise hair sheep and/or use aluminum electric wire which delivers a more powerful shock than hi-tensile.  Wool sheep often cannot feel the shock at all, especially when in full wool.

Wool sheep are not ideal for range grazing since the wool clip can be practically ruint if they find a patch of cockleburrs or other clinging seeds.

Though i did not consider it in my time allotment, sheep, ideally, need checking everyday – that fence can be blown over or something chase the sheep into the fence and they get caught up or they flatten it.  Rain and flood can knock it over, too.  Animals can be caught up in it that need rescuing or they die and the rest will all get out and scatter!  If you have 1000 acres and 2 sheep, in five minutes they’ll be at the far corners and separated.  When the Scriptures talk about sheep going astray – there is the proof of it!

In my case, i have a 35 minute drive to my farm.  Sheep are not practical at all if they are so far away that they cannot be checked on easily.  With cattle, unless during calving season or unseasonably hot or cold weather, they don’t need attention anymore than once every three days or so.  This greatly reduces my time spent on the road.

Sheep can be used to better clear brush and prepare pastures for renovation and improvement as long as their grazing is strictly controlled.  Sheep get out a lot!  Perhaps not out of the perimeter fence, but they, like all livestock, must stay within their alloted grazing or they’ll destroy a pasture.  If you have beautiful, level pastures with no ditches, draws, dips, or washouts, yet shade in nearly all paddocks (sheep sunburn and get very hot in the summer), you may have an ideal situation for raising sheep.

The biggest advantage sheep have over cattle at least in today’s marketplace is the initial investment.  And it is substantial. Taking our above example:

250 bred cow purchase@ $2500 is $625,000   (Requires 6 bulls for breeding – $5000 each or $30,000)

1250 bred ewes purchase $281,250 (Requires 25 rams for breeding – $500 each or $12,500)

However, nets cost $120 each and used regularly MIGHT last 2 years.  And as shown the labor is much greater.

So there are advantages and disadvantages.  To me, the market dictates raising cattle, because of the reduced cost of infrastructure and reduced labor.  However, if one had 1250 ewes, in my opinion, the infrasture needs to be in place to eliminate the labor of netting.  This is lots of posts and woven wire.

So, this all begs the question, ‘why did i purchase sheep in the first place?’  To be sure, my plan was that the sheep would basically live with and graze with the cattle and shift with them.  However, this never came about since they would not be contained by the 3 wire hi-tensile electrified fencing I installed for this purpose.  They learnt to jump through the two top wires, so that even though the wires were ‘hot’ the sheep were not shocked since they weren’t touching the ground as they jumped through.  I don’t know if they learnt this by accident or watched the dogs do it.  Plus any dip in the ground would provide a large hole for them to duck under.  It honestly, is impossible, from a practical standpoint to make them stay within the enclosure.  So, until i started containing them with the electric netting, they became regular fodder for predators despite guard dogs simply because they scatter like, –well, sheep.  From then on, i have two groups of animals to shift, with the sheep requiring far too much time for what they were worth.

So, the sheep will be sold over the next couple of months to free up time for family matters, to improve my sanity, and give my poor old bones a needed rest.

PS:

There are other major expenses involved to have such a scheme.  Not the least of which is needing about 1000 acres, which at current prices in north central Missouri is about $2800 to $3400 per acre. (IF you can find it for sale) Some people are very fortunate to find pasture to rent, but consider whether or not you’d want to make $150 per acre in infrastructure on someone else’s property.  You’d need a lifetime lease to justify that and they can still sell the land and you’d be out.  Plus the owner may not be agreeable to crisscrossing his or her property with fencing.  Remember, too, the animals have health issues including treating for disease (albeit very seldom), vaccinations, castrating, as well as marketing and trucking expenses.

Yesterday was prime example.  After the flash flood of early morning, I spent an hour and a half untangling and untwisting 30 feet of netting and resetting the remainder of the 164 foot net.  The 30 feet had been sucked down the creek and twisted incredibly tight about itself.
