摘要

Eight Holstein cows were used in a cross-over design to test whether concentrate allocation in an automated milking system (AMS) affects dry matter intake (DMI) and milk production. Cows were fed a high-energy partial mixed ration (HE-PMR) with 0.5 kg of AMS concentrate or a low-energy PMR (LE-PMR) with 5.0 kg of AMS concentrate. The AMS concentrate intake was greater and PMR intake was reduced for LE-PMR than HE-PMR. Milk, fat, and protein yields were not affected by treatment. In a guided-traffic flow barn, providing a PMR with greater energy density increases DMI, but has no effect on milk and milk component yield.
