The objective of this work was to study the effects of age at the beginning of forage supply (4 or 60 days) and weaning age (35 or 56 days) on the digestibility of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and gross energy (GE) and nitrogen balance, in the post weaning period, in Holstein and Holstein x Zebu crossbred bull calves. The animals were maintained in metabolism cages for feces and urine collection. A unique diet containing […]

This work was carried out to evaluate the agronomic characteristics (bedding, breakage, and productivity) and the chemical-bromatological of the green matter and silage of 19 cultivars of maize. The treatments were applied on 5 x 4-m plots arranged in a randomized block design with four replications. By the ocassion of sowing, doses corresponding to 500 kg/ha of the formula 4-14-8 (N-P2O5-K2O), were applied and at the 47 day of emergency, 60 kg/ha of N in broadcast. From the studied nineteen […]

This assay was conducted with sheep to evaluate in vivo digestibility of the dry matter and fiber fraction of broiler litters based on wood scraps, elephant grass Napier, corncob with husks and the aerial part of cassava. A completely randomized blocks experimental design with four treatments and five blocks with four sheep, considering the live weight of the animals, were used. Twenty Morada Nova sheep, white variety, with 18 months of age and live weight from 17.2 to 27.3 kg […]
