You know early grazing didn’t work in our
favor this year; however, those of you who were lucky enough to get your small
grain fields planted before the rain may have a chance to have an excellent
beginning and should be able to graze those fields much earlier than
usual. Of course we don’t need it washed
out and we need it to stay warn a little while longer. If these things fall into place early grazed
forage should contain 28-32% crude protein. It is important to remember, each
ton of forage harvested by livestock will remove 90-100 pounds of nitrogen.
Small grain forage that stands a foot tall will easily yield one ton per acre.
That means if you only applied 60 to 80 pounds of nitrogen per acre at
planting, most if not all of your nitrogen will be harvested with the first
grazing.
I think we can expect to see nitrogen
deficiency symptoms before the first of the year. If you are able to graze
early and remove the forage before then, nitrogen top dressing in December will
surely help produce more winter forage. If you delay that nitrogen application
until January or February, expect a forage growth loss.
In many cases, hay quality is below average,
so a few pounds of nitrogen may allow your winter forage to economically
supplement the hay.
According to Noble Foundation research, limit
grazing your small grains may be the best bet to extend that small grains
grazing and provide the necessary protein. Grazing steers as little as 15
minutes on small grains equals about 2.5 pounds of 20% breeders cube. Using forage supplementation in place of feed
can save money if managed correctly.
Producers should look at all winter feeding options to determine the
cheapest source of protein and energy to sustain suitable body condition scores
throughout the winter.
