Abstract

Trans-10, cis-12 conjugated linoleic acid (CLA) is a potent inhibitor of milk fat synthesis (Baumgard et al., 2002). Feeding supplemental CLA may be a means of ameliorating negative energy balance (NEB) post partum, potentially improving subsequent reproductive performance. A recent meta-analysis of 5 controlled studies where CLA had been supplemented to early-lactation dairy cows indicated that CLA supplementation significantly reduced interval to first ovulation and time to conception, and increased the probability of cows becoming pregnant (de Veth et al., 2009). The aim of the present study was to examine the effects of CLA supplementation on milk production and reproductive performance of lactating dairy cows in a field scale situation.
