We hypothesized that gestational nutrition would affect calf feed efficiency and small intestinal biology, which would be correlated with feed efficiency. Multiparous beef cows (n = 36) were individually fed 1 of 3 diets from d 45 to 185 of gestation

Two experiments were conducted to evaluate the effects of rumen-protected fat (RPF) supplementation after or during estrus synchronization on plasma fatty acid concentrations and reproductive performance of lactating beef cows. In Exp. 1, primiparous

Angus × Gelbvieh cows with 2 to 3 previous pregnancies were used to evaluate effects of maternal nutrient restriction on offspring adipose tis- sue morphology at standard production endpoints. At 45 d after AI to a single sire, pregnancy was confirm

Angus × Gelbvieh rotationally crossbred yearling heifers (n = 99, yr 1; n = 105, yr 2) were used in a 2-yr randomized complete block design experiment with repeated measures to determine the effect of feeding camelina biodiesel coproducts (meal and

Two experiments were conducted to compare ruminal, physiological, and performance re- sponses of forage-fed cattle consuming grain-based sup- plements without (NF) or with the inclusion (10%; DM basis) of a rumen-protected PUFA (PF) or SFA source (SF

Multiparous ewes received 100% (control, C, n = 13) or 50% (nutrient restricted, NR, n = 14) of NRC dietary requirements from d28-d78 of gestation. On d78, 5 C and 6 NR ewes were necropsied. The remaining 8 C and 8 NR ewes were fed to 100% of NRC fro

Twenty-four black-faced lambs (24 ± 0.4 kg initial BW) were used in a randomized complete block designed experiment to determine the effects of feeding 2 varieties of field peas on growth and carcass characteristics. Lambs were blocked by BW and ass

Under- and over-nutrition during gestation may influence fetal hypothalamic development resulting in individuals predisposed to adverse health effects. This study examined fetuses from obese and control ewes to determine whether dam obesity alters hy
