Effect of insulin administration during follicular growth on serum glucose and hormone profiles in ewe lambs

Autor: S. W. Beam, D. W. Holcombe

Publikováno v: Canadian Journal of Animal Science. 72:421-426

Twenty ewe lambs received either 0 or 1 IU of Lente insulin kg−1 body weight from day 12 of the estrous cycle until 24 h after estrus. Blood samples were collected at 15-min intervals for 6 h after treatment on days 12, 14 and 16 of the estrous cyc

Growth performance, serum hormones, and metabolite responses before and after weaning in lambs weaned at 42 days of age: effect of preweaning milk and postweaning alfalfa or grass hay diets

Autor: D. M. Hallford, L J Krysl, D W Holcombe, M B Judkins

Publikováno v: Journal of Animal Science. 70:403-411

Fourteen fall-born lambs were used to determine the effects of diet before and after weaning on intake, growth, serum hormones, and metabolite profiles. Before weaning, lambs were intensively sampled for 6 h at 35 and 42 d of age. Before sample colle
