Tips for Stockpile Grazing Timing, Fencing and Pasture Size

From December of 2016, here are tips on pasture size, fencing equipment and more, to help with successful stockpile grazing.

When to Start

If possible and practical, it is best to not start grazing stockpiled forage until it goes dormant. Until it goes dormant, every time that solar panel of leaves is removed, the plant will draw from the reserves in the roots. If you hurt those reserves too much, and you will set back spring growth. If you don’t allow longer rest period in the spring to allow the plant to build back roots and reserves, you can really hurt your forage stand. There are times where grazing can be beneficial, such as for reducing competition early spring for frost seeded legumes. We will consider it dormant at this point.


How Much to Give Your Livestock

If you are new to stockpiling, there are a few things to think about. It is usually best when first entering a field to give your livestock at least two or three days’ worth of forage. You should start the grazing process on the end of the field with the water. You might be able to use a portable watering system for a while moving it along with the livestock, but that type of system gets challenging to keep from freezing. Back fencing is not nearly as important once the forages go dormant, so there is nothing really wrong with just utilizing water on one end of the field, as long as the walking distance and the time frame on the field doesn’t create too much trailing.

The allocation that you gave the livestock can now be grazed down to the desired residual height, ideally still 3 to 4 inches for most fescues and orchardgrass. Once the plants are at that desired stop grazing height, it is time to allocate more. To get the highest efficiency, daily allocations are best, but you can increase the amount as needed, especially if you are going to be gone a day or so.

If you are back fencing, you need three sets which would include a reel, poly-wire, and enough step-in posts to complete a run across the field. If you are not back fencing, then two sets are best, but you can make it with just one. With two sets, you can have one in place, and move the second with less concern of the livestock moving faster than you do. If back fencing, the third fence is the back fence. Once the livestock are moved into the new allocation, the old back fence can be moved ahead of time for the next allocation. This is especially nice if you are fighting daylight or timing of that next move.

I prefer to keep things easy and also where I’m less likely to accidentally shock myself. Solid plastic handles on the end of the poly-wire means you can hang it on a hot or non-energized wire and it won’t be “hot” until you make it hot. You then make it hot using jumper leads which look like little miniature jumper cables. It also helps to have a set of these per run also. While I’m still on the topic, I recommend buying quality poly-wire! The best poly-wire has eight or more strands of stainless steel strands in it. I’m not a fan of poly-tape, which is very similar, but usually ribbon-like and about a half inch wide. The tape is harder to keep taunt and nearly impossible with ice or snow on it.

Strip grazing of stockpiled forage can be done on any size of field, but longer, more narrow fields are certainly the easiest to work with. When you are laying out new permanent fence divisions, consider this if you plan to do any stockpiling. My wife thinks that any run over 300 feet is too much when she has to fill in for me…so we have gone with more longer, narrower fields, and I have to admit I find it kind of nice too.

A step-in post with a smaller, yet strong steel tip and a foot peg for easy installation works the best for the frozen soil conditions that are ahead. When grazing heavier stockpile, you will find that the ground does not freeze much unless we get extended sub-zero temperatures creating a nice insulation blanket. Keep your choice of reels reasonably cheap at least to start with if you are going to be doing short runs. Longer runs make it easier to justify more expensive ones because of the gearing.

Good quality stockpile is usually tall fescue. Nothing stockpiles as well and holds its nutritional value longer through the winter as tall fescue. If you have stockpiled orchardgrass, use it first. Orchardgrass starts falling apart fairly quickly and has little value as winter progresses. Quality stockpiled tall fescue quite often has better feed values than a lot of hay that is fed at the same time. (We’ll talk more about this next week!)

Cows grazing on corn swaths in the winter snow in North Dakota. ARS researchers at the Northern Great Plains Research Laboratory have found that Northern Plains farmers can save money by allowing cows to swath graze throughout the winter. Various rotations of forages and legume-grass mixtures, when swath grazed, can provide protein-rich mixtures that can help beef up pregnant cows.

Sorghum-sudangrass has been frozen and dried off two or three weeks by now and could provide some grazing opportunities if still present. If you have ample stockpile of corn residues and annuals to continue grazing until the end of the year then you are already more efficient than most livestock producers; good job.

Keep warm and keep on grazing!

For more than 25 years, Victor Shelton, Indiana agronomist and grazing specialist with the Natural Resources Conservation Service, has provided advice about grazing’s best practices. He travels across the state conducting pasture walks, working one on one with farmers and participating in grazing talks. He also writes a newsletter called "Grazing Bites" as a way to talk about current and seasonal grazing issues and what farmers need to be prepared for.


  1. Very insightful tips and easy to adopt.

    Victor Shelton worth (re)reading anytime!
    Couple of thoughts from our experience:
    We’ve never used clips or leads to connect/energize; one more thing to keep up with. Either wrap the polywire tied to plastic handle around the hot wire. Or better yet buy a plastic handle that doubles as a direct ‘hot’ connection, depending how attached. Quick and easy, even with novices with fear of shocks.

    As for reels, just like polywire and handles, you get what you pay for. For the time saved, geared reels earn their keep quickly. Borrow a geared reel if you need to be convinced, or compare the two types at a pasture walk, trade show, etc.
    If you buy a cheap one (non-geared), perhaps your second or third reel can be geared. It’s all we buy now, and we’re very frugal…

    Keeping these polywire moves quick and simple makes it so much easier to arrange time away. Increasing the pool of helpers who can handle these moves.
