Limit-fed heifers generate less manure

Imagine 10 pounds less manure per heifer per day. That was one result of a study reported in the February Journal of Dairy Science. In the study, bred heifers limit-fed for 80 percent of intake generated 2 pounds less manure dry matter per heifer per day than ad-libitum-fed heifers. That’s 10 pounds less manure per heifer per day on a wet basis, says Pat Hoffman, dairy researcher at the University of Wisconsin’s Marshfield Agricultural Research Station. “We are exploring pushing the envelope on limit-feeding strategies for dairy replacement heifers,” Hoffman said last month at the Western Dairy Management Conference in Reno, Nev. Things look promising, but proceed with caution if you decide to use this strategy. More research is planned.
