ABSTRACT

Preweaning data on 511 spring-born calves from 187 Brangus cows and 129 Bonsmara, Brangus, Charolais, Gelbvieh, Hereford, and Romosinuano sires were measured over a 4-yr period to determine sire breed, sex, and age of dam differences under 2 preweaning forage environments: 1) native tallgrass rangeland (native) or 2) improved warm-season forages (improved). Sire breed differences in birth weight varied across forage (P < 0.05) with Romosinuano-sired calves on improved forag...

Evaluating Texel-, Suffolk-, and Columbia-Sired Offspring: II. Postweaning Growth and Carcass Traits Under Feedlot and Pasture-Feedlot Finishing Systems1
Professional Animal Scientist ; Abstract A terminal sire study was conducted to evaluate postweaning growth and carcass traits of Texel-sired offspring compared with Suffolk- and Columbia-sired offspring. The lambs were weaned at an average age of 70 and 94 d during the 2-yr study, respectively. After weaning, lambs from each

Influence of Live Weight Gain During the Winter Grazing Period on Subsequent Grazing and Feedlot Performance1
Professional Animal Scientist ; Abstract Crossbred steer (n = 297) and heifer (n = 125) calves were used in three experiments to determine the impact of restrictive ADG during the winter grazing period on subsequent BW gains. Calves were born in the spring, weaned in the fall, and transported from Northwest Arkansas (360 km;
