The experiment was carried out to evaluate addition effects of five urea levels with four ammonization periods on Agave sisalana residue chemical composition in the different storage times. It was used 300 kg of this co-product, equally distributed in 60 black polyethylene bags, which urea was added in the following concentrations: 0, 2, 4, 6 and, 8% over 0, 2, 4 and, 6 weeks storage periods. It was made determinations of dry matter (DM), crude protein (PB), neutral detergent fiber […]

An experiment was conducted to study the effects of allowance of ammoniated rice straw on the voluntary intake (VI) and digestibility of dry matter (DMD), and on the intake, excretion, digestibility and N balance. Fifteen adult sheep, males, castrated, with average weight of 63.8 kg, individually kept in metabolic cages, were used. The levels of straw fed to the animals were: 1.5; 3.0; 4.5; 6.0 and 7.5% of live weight. A supplement (200 g/animal/day of corn) was used to supply […]
