Nutrition and management of the beef unit for production of slaughter animals on range and improved pastures in southeastern Oregon

Creator:: Daugherty, Dennis A.
Abstract:: Studies were conducted over a two year period to evaluate alternative finishing methods for spring and fall-born beef cattle. Management alternatives from birth to slaughter included season of calving, lactating cow nutrition, preweaning calf nutrition, weaning age, calf and yearling winter nutrition, range and irrigated pasture supplementation, grazing practice, range...

Computer simulation of beef cattle production systems in the Llanos of Columbia

Creator:: Levine, Joel Martin
Abstract:: A simulation model capable of execution on a programmable calculator was developed to study voluntary intake, liveweight change, and fertility of grade Zebu cows in the Llanos of Colombia. Organic nitrogen in the diet and meta bolic weight were used to predict intake; age, liveweight, and energy concentration were the...

Effect of Zinc, Copper and Selenium supplementation on the humoral immune response of weaned beef steers

Creator:: Dill, Thomas O.
Abstract:: Two studies were conducted to determine the effects of zinc (Zn), copper (Cu) and/or selenium (Se) on the humoral immune response of weaned steers fed diets deficient in these minerals. Steers were bled weekly for eight weeks to measure plasma mineral levels. Humoral immune response was measured as antibody response...

Simulation of cattle cycle demography: cohort analysis of recruitment and culling decisions in the national beef cow herd

Creator:: Nordblom, Thomas L.
Abstract:: This study expresses the hypothesis that historical patterns of national beef cow herd accumulation and liquidations (the cattle cycle) have been related to investment incentive differences across cow ages through time, resulting each year in changes in herd age structure, performance and potentials for adjustment in subsequent years. A review...

Nutritional strategies to improve the reproductive performance of beef females

Creator:: Cappellozza, Bruno Ieda
Abstract:: In the first set of studies, 2 experiments evaluated the influence of supplement composition on ruminal forage disappearance, performance, and physiological responses of Angus × Hereford cattle consuming a low-quality, cool-season forage (8.7 % CP and 57 % TDN). In Exp. 1, 6 rumen-fistulated steers housed in individual pens were...

Alternate methods of fattening steers in Eastern Oregon

Creator:: Whittington, David Lynn
Abstract:: Studies were conducted at the Squaw Butte Experiment Station during two consecutive years to : (1) compare various internal indicators and chromic oxide to estimate forage intake and fecal production, (2) compare methods of producing slaughter weight steers using maximum quantities of forage and minimum quantities of grain. Actual fecal...
