Randomized clinical trial evaluating the effects of the administration of acidogenic boluses at dry off on udder health

Abstract

High milk production at dry off is a risk factor for intramam­mary infections (IMI) postpartum due to milk leakage and im­paired formation of the keratin plug during the dry period. The use of acidifying agents at dry off can induce a temporary feed intake reduction and decrease in milk yield of high-producing dairy cows. Thus, acidogenic boluses are a potential tool to help maintain udder health around the dry period. The study aim was to evaluate the effects of the administration of acidogenic boluses at dry off on udder health.
