The objective was to evaluate body weight, leg weight and morphologic aspects of the muscle fibers of the flexor hallucis longus muscle and electrophoretic profile of myosin heavy chain of four strains of broilers, reared in confinement and semi-confinement systems. 1440 chicks were randomly assigned in a 4 × 2 factorial arrangement: four strains (Ross 305, Master Gris, Label Rouge and Vermelhao Pesado), two production systems (confinement and semi-confinement), with four replicates for each treatment. Four birds were sacrificed for […]

It was evaluated beef heifers performance from three until twelve months of age, when they were reared in cultivated pasture soon after their weaning (experiment 1) and in the first winter post-weaning (experiment 2), with or without the supply of energy supplements to the animals. From 02/16 to 04/21/2001, the heifers stayed in Pearl Millet pasture, exclusively under grazing (PAST1); supplemented with milled corn grain (PAST1/C) or supplemented with pellet citric pulp (PAST1/P). From 07/13 to 10/09/2001, the heifers were […]
