Abstract

20 Saanen goats, 10 first-lactation (P1) and 10 of posterior lactations were examined for a period of 150 d ays lactation. There were two daily milking and a daily milk control. In order to evaluate the chemical composition and somatic cell counts, samples were collected biweekly. Net protein requirements were based on milk production and protein composition of milk, and net energy requirements were based on milk production and fat, protein and lactose composition. The lactation peak was later for P1 goats and persistence of lactation was higher for the posterior lactation ones. Lactation order influenced milk nu trient concentrations, while P1 goats presented greater percentages of this parameter in comparison to the others. The protein percentage remained unchanged. Net protein and energy requirements were different for goats in different orders of lactation.
