The ongoing drought, limited forage supplies, high hay prices, and rising grain prices have made managing feed costs extremely difficult for most Kansas cattle producers. US livestock specialist Karl Harborth explains some issues to think about when purchasing feeds.
Limit wastage
Another way to conserve feed resources and
minimize cost is to limit wastage. One way to do so is to feed controlled
amounts of hay. A dry, pregnant cow will eat 20 to 30% more hay than her needs
when allowed free access to hay. A study from Purdue estimates that hay refused
or wasted when cows were fed a 1-day, 2-day or 4-day supply per feeding was 11%,
25% and 31%, respectively. The second way to limit wastage is to evaluate the
delivery system in which hay is fed. Hay feeders that have a barrier (cone,
double ring, or slanted bars) can reduce hay wastage by 50% compared to
conventional bale rings. A study conducted at Michigan State University showed
cone type feeders to have wastage of 3.5% of dry matter and ring feeders to have
6.1% wastage.
