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...

Scrotal circumference measurements as an indicator of growth in the male beef animal

Creator:: Pirelli, Gene J.
Abstract:: Testes size as an indicator of future growth was examined in a total of 45 bull calves from spring calves born in 1978 and 1979. Scrotal circumference measurements were used as the physical indicator of testicle size in the live animal. Growth traits studied were preweaning average daily gain, weaning...

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...

Effects of two forms of intrareticular selenium supplements on beef cow selenium status and on the transfer of selenium from dam to offspring

Creator:: Campbell, Donald T.
Abstract:: Two concurrent studies were conducted to evaluate the effect of selenium (Se) supplementation on beef cows. Trial 1 was designed to evaluate the safety and efficacy of two intrareticular Se supplementation delivery systems. Trial 2 was designed to evaluate the transfer of Se across the placenta and through the colostrum...

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...

Analysis of two alternative management systems for the production of fall born beef calves in western Oregon

Creator:: Rosecrans, John Gerald
Abstract:: Two management systems were evaluated in terms of the effects on calf growth, on calf weight produced per cow per year, and on reproductive performance of fall calving cows. The alternative management systems tested were twin foster calf production and, delayed weaning, production of single suckled calves weaned at the...
