Energy and protein levels in dairy cow diets to recover milk ethanol stability

The objective of this study was to evaluate the ef- fect of energy and protein in the diet on the recovery of milk ethanol stability (MES) induced by feed restric- tion. Twelve Holstein and Holstein x Jersey crossbred cows with an average of 146 ± 50 d in milk, 575.4 ± 70 kg of body weight, and 18.93 ± 5.46 kg/d of milk yield were distributed in a 3x3 Latin square design with 3 treatments and 3 experimental periods. Each experi- mental period lasted 24 d, comprising 3 phases: a 13-d adaptation...
