This trial was run at Estación Experiment Agropecuária of INTA (EEA-INTA, Rafaela), Argentina. Thirty-two high producing Hostein-Argentina dairy cows were used in early lactation, aiming to evaluate blood parameters at two levels of protected fat (0 and 400 g/cow/day) and two types of alfalfa (fresh or haylage). All cows were submitted to a pre-trial period of fifteen day in two groups: with and without fat supplementation. The animals, post-partum, were allocated to paddocks with green or pre-dried alfalfa, comprising, then, […]
