The objective of this work was to evaluate the intake and apparent digestibility of nutrients of elephant grass forages, alfalfa and coast-cross grass hays in adult horses. Eighteen adult Mangalarga Marchador mares were allotted to a completely randomized design with three treatments that consisted on diets with the following forages: T1 – elephant grass, T2 – alfalfa hay, T3 – coast-cross grass hay. The animals were ad libitum fed twice a day. The experimental period was constituted by a phase […]

The net requirements of energy for the maintenance of bulls from four Zebu breeds (Gyr, Guzera, Mocho-Tabapuã and Nellore) were estimated with 63 bulls averaging 24 months of age and 366 kg initial LW and (15 Nellore and 16 from the Gyr, Guzera and Macho-Tapabuã). Fifteen animals, four Gyr, Guzera and Mocho-Tabapuã breed and three Nellore breed, were slaughtered at the beginning of the trial and the remaining were allotted to four groups of 12 animals, being three animals from […]
