The inclusion of four lactose levels (0, 7, 14 and 21%) in pre-starter diets for piglets was studied to determine the best level of lactose inclusion in weanling diets at this age. The experimental diets were fed from the weaning day to 14 days post weaning, but the performance was followed until the end of the nursery phase, at 35 days post weaning. The average daily gain (ADG) and the daily intake (CRD) from 0 to 14 days linearly increased […]

This trial was conducted to evaluate production levels of native breed ewes of Northeast Brazil mated to rams of specialized meat-type breeds. A total of 305 lambings from 134 ewes over three periods of mating were used to determine weaning rate, survival rate and live weight at weaning and total weight of weaned lamb. The hairsheep ewes were mated in a rotational scheme of the use of rams from Santa Inês, Hampshire-Down, Ile-de-France, Suffolk and Texel breeds. Live weight at […]
