SUMMARYVarious physiological characteristics of castrate male sheep fedad libitumwere studied between 1986 and 1987 in Australia. The sheep were between 20 and 45 kg live weight (LW) before and during fattening. Sequential data on body composition, e

A computer program to simulate rumen function in sheep is described. It predicts the degradation of dietary components within the rumen, products of fermentation, microbial growth yields and the flow of protein and other materials from the rumen. Inp

SUMMARYVarious measures of skeletal size were made on five or six occasions on 30 Dorset Horn and 30 Corriedale sheep (10 entire males, 10 females and 10 castrated males) commencing at 1 month of age (live weight 10 kg) and then at increments of 10 k

SummaryMeasurements of skeletal size were made at 2–3-month intervals on 30 Border Leicester × Merino castrate male (wether) sheep between 2 and 27 months of age. Fifteen sheep were fed ad libitum on a high-quality diet and the other 15 half the a

SUMMARYCorriedale and Dorset Horn castrate male (wether) lambs reared at pasture were weaned at 19 kg live weight (LW), brought indoors and fed a high protein diet such that half of each group grew at ca. 200 g/day and the other half at ca. 100 g/day
