Using a linear statistical model (GLM/SAS) the reproductive performance and growth of 480 Nellore heifers were evaluated from the age of 7.5 to 17/18 months under four feeding systems during the dry period (96/05 to 96/10): Brachiaria brizantha cv. Marandu pasture (B); Brachiaria brizantha cv. Marandu pasture + Anipro (BA); Pennisetum americanum cv. (L.) Leeke (Pearlmillet) (M) and Brachiaria brizantha cv. Marandu pasture + Sal Ouro (BS). At the end of supplementation all heifers were moved to a paddock of […]
