At frost last year in late October, I calculated I had enough forage under the very worst of conditions to make it through to at least April 15.
This estimate was done based on acres used per day and acres left to graze, plus some extra days for bale grazing and potentially some possible days for grazing in the hay meadow, if needed.
As it turned out, on May 7 I still had about a month of nice, mixed forage with plenty of new and some old forage (see video). For those of you who don't live in native-grass country, this leftover forage is really important to get through the spring until ample forage appears in late spring.
There are fundamentally two reasons I had so much more forage than I planned. First was the fact I moved into forage that was much better -- more copious and better quality -- than what I grazed during the growing season. Second, as the forage quality declined in late summer and early fall I had slackened up on my grazing pressure and consumption in an effort to improve quality and aid body condition on the custom cows. This resulted in significantly less animal days per acre in my calculations.
Once the frost killed the forage, I switched to much higher consumption levels, more severe grazing, and the use of supplemental protein to maintain body condition. A decision with the owner of the cattle to let the cows, which calved in late summer through the fall, slowly lose some condition and then rebreed in summer let us cut into what would otherwise have been a costly protein bill. To a lesser degree, some fescue and other cool-season grasses in the understory of the mature warm-season forage helped with protein content for the cows.
Just as important as cow condition is the way the cows and I were preparing the ground for growth this spring and summer. We consumed and tampled the vast majority of the standing forage, leaving the soil fertilized with urine and dung and ready for spring growth.
I had purchased some native-grass hay from a neighbor and used it in mid winter for bale grazing purchased, pregnant heifers. This offered me a higher stocking rate, plus the potential to add fertility and a seed source to some of the poorest land on the farm, and help in transitioning from custom-grazed cows to owned cattle.
Most of the winter we grazed at stock densities of 60,000-150,000 pounds per acre. Because much of the grazing was done in strips away from water, I could adjust stock density up or down a little bit from day to day to consume or leave more forage behind the cows and calves. If I gave too much forage one day, we could cut back a little the next and expect them to eat more of the unconsumed dry matter.
In a very wet winter we left behind a lot of hoof prints and some areas that were truly pugged. The oldest areas now are turning beautifully green with new forage.

<p>Cows really relished any area with heavy fescue coverage like this pond dam. The extra protein from green forage helped cut the purchased-protein costs.</p>

<p>All-natural 38% protein cubes served as the cheapest and primary protein souce for the custom-grazed cows through the winter.</p>

<p>Feeding protein cubes under the electric fence offers great livestock control and plenty of "bunk space," since the animals can be spread out and kept in a line by density with which you pour out the supplement.</p>

<p>There was plenty of dry forage in November standing for the cattle to use. There was no damage from trampling, urine or dung outside the electric fence, and that kept it standing through a very rainy winter.</p>

<p>The first and only significant snow of the winter fell November 12. Cattle weren't bothered and kept right on grazing the ample standing forage.</p>

<p>Dung was stacking up more than one would call ideal through the winter, but the owner wanted to cut protein bills and rough the cattle through because rebreeding on former summer-fall calvers wouldn't be done until well into summer.</p>

<p>The author's creek crossing was often flooded, a testament to severity of the rainy winter. The native forage, however, held up well through it all.</p>

<p>In early January, the author moved cattle to north perimeter fence with neighbor and began grazing a firebreak along the entire fence. Peace of mind and good grazing rolled into one package.</p>

<p>All water points on the farm are temporary and are built with polywire and step-in fence posts. As a bonus, keeping electric fence over a water point is always a great idea because it constantly retrains the cattle to electricity and it keeps them polite around the water source.</p>

<p>In late winter, author and cattle owner began to experiment with non-protein nitrogen as either a sole nitrogen source or a supplement to the all-natural protein cubes. NPN feeds normally use feed-grade urea or a similar product called biuret.</p>

<p>In early February author brought in purchased, pregnant heifers to transition from custom grazing to owned cattle. There was still plenty of forage, and this was an opportunity to provide from purchased hay.</p>

<p>Newly arrived heifers were fed under electric fence in pens along existing fence until fully trained and respectful of electricity. Afterward they were moved onto pasture.</p>

<p>Electric fence over the water tanks in corrals and pens is another important training aid for new cattle. It also helps protect the water valves and plumbing.</p>

<p>Even with heifers brought into the corral twice for only three to four days each time, the wet winter turned the corral into a mud pit. Not so with pastures, which mostly had only ATV traffic and cattle constantly moving to fresh ground.</p>

<p>Once adapted to daily moves on pasture, the new heifers calmed down quickly and some even began to take treats from the author's wife.</p>

<p>This view shows the forage grazed and trampled in the foreground, along with some puddling from fresh rainfall, with the custom cows moved into fresh standing forage farther up the hill. The date was March 18.</p>

<p>There was still plenty of standing forage, a beautiful mix of old and new, as author moved the heifers into it the first week of May.</p>
