Pinus ponderosa or western yellow pine (Pinaceae) is widely distributed in the US, but is most abundant in the western US and western Canada. It was suggested by L. R. James et al. that in addition to the possible toxins in Pinus ponderosa needles, s

Data from a 3-yr study in Montana were utilized to evaluate impacts of season of calving, weaning strategy, and retained ownership of steer calves on enterprise profitability. Calving seasons were late winter (LW), early spring (ES), or late spring (

A 3-yr study was conducted to evaluate the effects of calving system, weaning age, and post- weaning management on growth and reproduction in beef heifers. Heifer calves (n = 676) born in late winter (average birth date = February 7 ± 9 d) or early

In environments where cool-season forages are the major forage resource, shifting calving season from winter to spring may match up forage nutrient supply with animal nutrient demands and thereby reduce purchased feed cost. However, calf BW at weanin

The impact of varied calving and weaning times on post-weaning production of steer calves was evaluated in a 3-yr study. Steers (approximately 12 steers per calving-weaning treatment per year) born in late winter or early spring were weaned at 190 or

A 3-yr study evaluated late winter (Feb), early spring (Apr), and late spring (Jun) calving systems in conjunction with varied weaning strategies on beef cow and calf performance from Northern Great Plains rangelands. Crossbred cows were randomly ass

Our objective was to determine if serum concentrations of leptin could be used to predict carcass composition and merit in feedlot finished cattle. Two different groups of crossbred Bostaurus steers and heif- ers were managed under feedlot conditions

Cattle of varied genetic growth potential may respond differently to management strategies because of altered nutrient demands for growth. An option for postweaning calf management is use of improved pastures for grazing. A 3-yr study (1990 to 1992)
