Now, how do I feel about it? I love it! Rain waters my grass. Managing the cows properly will also result in timely planting of future seed. Since my grass this year shot to the reproductive stage in May before I could graze it, a lot of grass went to seed. Utilizing high-density grazing, my first time through the paddocks with the cows resulted in a lot of grass seed being planting in moist soil with cattle hooves. As I’ve said before, I strive to organize the grazing paddocks so that the cows have enough to eat for one day or less plus trample at least half of the forage available. That trampling effect lays a layer of grass down as mulch and future organic matter, plus shakes loose all the grass seed ready to increase my grass sward.

I believe that years like this can help focus the debate. We grow way too much corn and soybeans in Iowa. We use way to much questionable hilly erodible ground for row crops, when those areas should be planted to grass or some long-term perennial that will hold the topsoil. The more grass we plant and the more focus we have in managing animals in such a way as to create more topsoil, the more water we’ll hold, the less floods we’ll have, as well as minimizing drought.

What I mean by low-labor is cutting out much of the work in raising sheep (and animals, for that matter). I have a hair-type sheep breed (St. Croix), so no shearing. I don’t clip their hooves, I don’t dock their tails, I don’t worm them (they are parasite-resistant), I don’t feed them grain, I don’t help them with their lambing, I don’t call the vet out for every issue. While some may consider this inhumane, I consider it a program of restoration.  Restoration in this instance and in my opinion is getting farm animals back to a status of health and productivity without a lot of human intervention and cost. I always ask myself: “If I wasn’t here, what would they do”? The truth is, wild sheep do quite well. Somehow they manage to live without worming, tail docking, hoof clipping, lots of grain, barns, and lambing assistance. Those that can’t adapt, die — and don’t pass on those genetics that won’t thrive in that environment.

Now, I know I’m generalizing. There are always specific instances where my broad-sweeping statements don’t apply. HOWEVER — all I know for sure is once I got my genetics right and my mindset right, my sheep herd thrived. I breed them in December for a May lambing. This means their third tri-mester finds them on grass (late March into April) right when their nutritional needs are the greatest. They give birth on grass during a time when it’s not too hot, the grass is growing. The lambs that I’m setting aside for my meat sales will finish in November, right when the grass is not growing (and I don’t have to feed hay).  These sheep came from a parasite resistant flock in the same climatic zone that I live in, so they are geared to thrive in humid environments (sheep traditionally have been raised in dry, cool, arid climates).  If a ewe or ram doesn’t do well in my program, I sell her or him. I’m ruthless with this, because if I’m sympathetic and introduce a lot of medication or labor, then eventually I won’t have a low-labor sheep herd.

The greatest part about these sheep is that they will graze the dead grass in winter, and dig down through the snow and ice to eat it. I didn’t feed any hay last year, and we had a very hard winter. The sheep stayed outside, ate grass all winter, and thrived. That mean their manure and urine was deposited on the pasture, not in the barn (where I would have to clean it up, put it in the manure spreader, and take it out myself).  Interestingly enough, so many people thought I was crazy to not feed hay. They almost got angry at how I was such a bad shepherd.  In looking at my sheep now, I’m amazed at how healthy they look, their lambs are fat and growing, the ewes are contented.

Bottom line: since they graze during the winter, I don’t have to make or buy hay (reduction in diesel fuel, equipment repairs, capital expenses). I don’t have to haul manure (reduction in my time spent cleaning, diesel fuel for tractor to pull manure spreader, equipment repairs, capital expenses).  I don’t have to put up expensive buildings to house the sheep as my herd grows (reduction in capital expenses).  Diesel fuel is the life blood of US agriculture – cut that off and the farm economy comes to a screeching halt. One of my goals is to create a farming system that approximates low labor, little to no reliance on diesel fuel, environmentally-sustaining and economically viable.

So far, so good.

The subjective metric is actually a eyeball evaluation of the condition of the cows. It seems obvious to animal raisers that making animals graze close together could result in lower selectivity (the amount of forage available to the animal at any given point in time). This would be true but if the animals were left in the small grazing area too long — but the idea is to move them often and in high group numbers, thus giving them a high selectivity. The component that is often overlooked and almost immediately rejected by conventional farmers and ranchers is the labor involved in moving cows and electric fence so often — this is key, and it is a cost that must be included in the evaluation of the enterprise.

The idea of mob grazing is to trample at least half of the available forage on the ground and eat approximately the other half. This is accomplished by long narrow sections of strips – encouraging the cows to move up and down. The reason for the desire for trampling grass is that grass becomes food for soil microbes. That soil life will take the “organic matter” and decompose it, increasing biological soil life, increasing fertility, and literally over time creating more topsoil. The trampling effect also has another benefit in that the sharp hooves of the cows concentrated in an area “plant seeds”. There are literally billions of seeds, grass seeds, in the soil already — why spend money for more seed?

This approach to grazing and utilization of animals is on the leading edge of farm sustainability.  With the right genetics, the right rest period for the plants and high-density grazing, farms can recreate topsoil that has been eroded away due to questionable cultivation practices or inadequate grazing management at an extremely low cost.

Hair sheep grazing through snow

It’s now the end of February, and I’ve fed very little hay. It’s amazing to see the sheep dig down through the snow and eat the grass. When one thinks about it, stockpiled grass (grass that was allowed to grow during the fall without cutting for hay or allowed to be grazed) is in fact “standing hay”. The idea is to have the animal go out there and harvest the feed themselves, not us humans spending a huge amount of money, time, effort and energy harvesting the hay and bringing it to the animal. Much less costly, much less effort, and the animal is healthier I believe, in the end.
