The age at which ewes reach their maximum live weight depends on the environment. At Lincoln College ewes increase in live weight from the two-tooth stage to a maximum at 56 years and then decline. The increase is about 8 kg. In the high-country environment no such increase occurs. Lambs...
Lambs that gain more weight survive winter better and have higher lifetime reproductive success. As many as two million bighorn once lived from Canada to northern Mexico. In the 1800s overhunting, habitat loss, and livestock diseases nearly drove the species to extinction. Despite conservation ...
weaned before winter, when four to six months old. Malnutrition rather thanpredationaccounts for manylambdeaths, as lactating mothers may reduce milk production in order to store fat against the coming cold. Lambs that gain more weight survive winter better and have higher lifetime reproductive ...
Slaughtering kids/lambs at specified age and weight of specialized goat and sheep meat breeds might promote high muscle deposition and a desirable carcass fat cover, culminating into meat with a more adequate nutritional profile and health properties for human consumption. In this case, animal factors...
Body weight (BW) and crown-rump length measurements showed that a caprine foetus weighing 51.13 ± 20.37 g and measuring 11.27 ± 1.36 cm (mean ± SD) at 6–8 weeks, attained a weight of 1371 ± 175.1 g and length of 31.69 ± 1.36 cm by 18–20 weeks. An ovine foetus, however, ...
We investigated the effects of vegetation biomass, crude protein content of consumed forage, age, sex and reproductive status on bite rates in Rocky Mountain bighorn sheep. We expected higher bite rates and vigilance in lactating females with young and higher bite rates in young growing individuals...
Foot scald, an interdigital dermatitis, is caused primarily by D. nodosus alone. Clinical signs. Varying degrees of lameness are observed in all ages of animals within 2–3 weeks of exposure to the organisms. Severely infected animals will show generalized signs of weight loss, decreased ...
The phenotypic expression of growth-related traits in lambs, such as birth weight and the early growth rate, specially until weaning age, are determined not only by offspring own genetic potential but also by the maternal environment to provide an appropriate environment in the form of suitable ...
Hyperinsulinaemia in the four Finn-Dorset clones (Fig. 2c) was certainly influenced by the level of body fat, as weight loss reduced plasma insulin concentrations (Fig. 2f), consistent with improved peripheral insulin sensitivity which can be expected following weight loss in sheep46. However, ...
Renal blood flow was determined by the radionuclide-labeled microsphere method in the fetal lambs and by measuring "C-inulin clearance in the newborn lambs. The fetal and newborn kidneys consumed oxygen at rates of 123 2 16 and 785 2 79 pmol/min/100 g kidney weight (mean f SEM), ...
