Male and ♀ Soay, Welsh Mountain (WM), Southdown, Finnish Landrace (FL), Jacob, Wiltshire Horn (WH) and Oxford Down (OD) sheep, and feral goats, were slaughtered when proportionately 0.40, 0.52, 0.64 or 0.76 of mature body weight. On average, carcasses contained 583 g muscle, 243 g ...
Soay, Welsh Mountain, Southdown, Finnish Landrace, Jacob, Wiltshire Horn and Oxford Down sheep and feral goats were slaughtered when at 0.40, 0.52, 0.64 or 0.76 of mature body weight. The effects of stage of maturity, breed and sex were examined in a number of carcass traits. As a ...
Regardless of the source of herbage consumed, sheep daily liveweight gains were in the range 200–250 g/kg DOMI. Liveweight gains of sheep grazing crop were also predicted from their calculated metabolisable energy intakes and requirements for maintenance and were within 1% of the observed live...
weight and curiosity of all ages of animals, especially the investigative and climbing behaviors of goats. Chain-link fences are dangerous because goats (as well as some breeds and ages of sheep) are curious and tend to stand on their hind legs against fencing or walls. Forelimbs may be cau...
Effects of livestock grazing on physical and chemical properties of sandy soils in Sahelian rangelands Grazing treatments were a factorial arrangement of two stocking rates (62·5 and 125 kg live weight ha1) and four sheep:goat ratios (0:6, 2:4, 4... P Hiernaux,CL Bielders,C Valentin,...
At 28 kg live weight, ram lambs had: heavier heads, feet, reticulo-rumens and livers; higher muscle and bone and lower fat proportions in the carcass; lower muscle: bone and higher muscle: fat ratios; higher proportions of carcass but lower non-carcass fat than had wether and ewe lambs....
Urinary excretion of purine derivatives (PD) was used to estimate the microbial N (MN) supply to sheep in three experiments designed to examine the effects of DMI and BW on the efficiency of microbial N supply (EMNS) to the host animal. In Exp. 1, four sheep of about 45 kg BW were...
Body weight gain or losses are then predicted as: BWv (kg/d) = EB/((9600/0.6) x km) [13] where EB is energy balance (equation [12]) and km is equal 0.64. Pregnancy energy requirements Pregnancy requirements are estimated in accordance with the CSIRO (1990) pregnancy sub model, which...
Changes in wool growth and the skin of Merino sheep following administration of cyclophosphamide Two Merino sheep were dosed orally, and two intravenously, with cyclophosphamide at the rate of 30 mg/kg body weight; the effects on wool growth were measu... PJ Reis,RE Chapman - 《Australian Jour...
Water was given once in 24, 48, 72 and 96 h. Free water intake decreased linearly (P< 0·01) as the period of water deprivation increased but feed intake was not similarly affected. There was a marked decrease in live-weight gain and consequently a decline in feed efficiency (kg gain/...
