The Revista Brasileira de Zootecnia (RBZ) is a publication dedicated to the broad field of Animal Science. We publish high-quality, original scientific research that spans across diverse areas within the discipline. The scope of RBZ encompasses a wide range of topics, including aquaculture, biometeorology and animal welfare, forage crops and grasslands, animal and forage plants breeding and genetics, animal reproduction, ruminant and non-ruminant nutrition, meat science and muscle biology, precision livestock, and animal production systems and agribusiness.

The experiment was conducted at the Goat Husbandry Sector of FMVZ – UNESP – Botucatu Campus, with the purpose of studying the influence of recombinant bovine somatotropin (rbST – commercial name: Boostin 250 mg) on the lactation curve, milk production, milk constituents, body weight and body score of goats during the lactation cycle. Twenty-one Alpine Brown goats between 1½ and 4 years old were used, randomly allotted to three treatments with seven animals each: control (T1 – no rbST), complete (T2 – rbST after the milk production peak) and low production season (T3 – rbST during the low production season). All animals received the same diet, excepting the amount of concentrate, which was adjusted according to milk yield. No increase in milk yield was observed in the treated animals, but lactation persistency was greater in these goats. The body weight and the body score also did not show significant difference between treatment and control animals.
