When profit margins get tight, it’s not uncommon for dairy operations to look for opportunities to cut costs. An area that may offer some cost-saving benefits are bred heifer diets.

Forages in the bred heifer diets can be rearranged and potentially offer significant savings, says Jason Leonard, calf and heifer specialist with Purina Animal Nutrition.

“It’s not uncommon for bred heifers to be fed free-choice corn silage and grass hay along with 5 pounds of grain,” says Leonard. “Not only is this diet expensive, it can create over-conditioned heifers with post-calving problems.”

Corn silage hybrids have evolved over the years and have generally gotten higher in quality to the point that they are too energy-dense to feed to bred heifers as their main forage source, he explains. Leonard notes that a simple way to fix this problem and save money is to feed a high-quality hay, haylage or small grain silage in place of the corn silage. These forages, when made correctly, can supply 100 percent of the energy and protein needs of the bred heifer without the use of purchased grains or proteins. A diet like this normally only requires the purchase of a mineral pack that may have a feeding rate of 0.10 to 0.50 pounds, depending on the mineral make-up of the forage.

“If you are tight on forage supplies and buying grain or commodities is easier to manage, a limit-feeding approach should be looked at,” he says.

University research on this type of feeding program has shown results while saving the farm money on heifer inputs. View Penn State’s research and suggestions for limit-feeding heifers.
