A study was conducted to evaluate the effects of level and source of fat in the diet of gestating beef cows on the postpartum performance of the dam and the progeny. Each year, 75 mature pregnant (183 ± 4.8 d until calving) Angus cows with similar BW (663 ± 21.

Each year, 75 multiparous (≥3 calving) pregnant Angus cows were stratified by BW (663 ± 21.5 kg) and BCS (2.

With numerous environments and for outcrossing plant species, computation is facilitated using reduced animal models. The development of efficient plant breeding strategies requires a knowledge of the magnitude and structure of genotype-by-environment interaction.

Verticillium wilt (VW) caused by Verticillium albo-atrum occurs in many irrigated alfalfa (Medicago sativa) fields in southwestern Saskatchewan, Canada, but is very rare in dryland stands. A trial was established in 1994 to determine if incidence of VW is affected by the amount of irrigation water applied. A line-source irrigation system was used to produce an irrigation water gradient on two adapted alfalfa cultivars, Beaver (VW-susceptible) and Barrier (VW-resistant).
