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...

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...

Population analysis of a commercial beef cattle herd

Creator:: Schons, Debra Jo
Abstract:: Twenty-four years of records (1958-1981) from a commercial Angus ranch were utilized in a population analysis to characterize the herd as a biological unit. The herd averaged 632±129 cows and 123±6 replacement heifers with all replacement heifers and many bulls from within the herd. Life tables were calculated for seven...

Growth and carcass merit of purebred Jersey steer calves finished on grain-based diets at two different energy levels

Creator:: Tschida, Garrett L.
Abstract:: Purebred Jersey steers are often overlooked for beef production due to the perceived poor growth and production. Currently dairy persons marketing their steer offspring are receiving minimal compensation due to lack of demand by beef feeders and a saturated veal market. Twenty purebred Jersey steers were used to evaluate lifetime...

The Effects of a Dietary Immunomodulatory Supplement on the Immune-Metabolic Axis in Growing Beef Cattle

Creator:: Armstrong, Shelby A.
Abstract:: To evaluate the immunologic and metabolic effects of OmniGen-AF® (Phibro Animal Health corporation, Quincy, IL; OG) supplementation in growing beef cattle, we designed three studies using replacement beef heifers (8.5 and 10.5 months of age) and steers supplemented across backgrounding, transition, and finishing periods. In Study 1, the effect of...

The effect of certain production factors and rates of gain on carcass characteristics of beef steers

Creator:: Thompson, Kenneth Earl
Abstract:: The purpose of the present study was to determine the association of initial weight, average daily gain, days on feed, percent total digestible nutrients (TDN) and percent digestible protein in the ration with USDA carcass grade, marbling score, conformation score, back fat thickness and area of longissimus dorsi of beef...

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...

Inheritance of antibodies synthesized against IBR vaccine and of complement C3 component in weanling calves

Creator:: Muggli, Noelle Elizabeth
Abstract:: Three sets of blood samples were taken from 532 beef calves of two populations at 24 to 48 h after birth, at an average age of 164 d (at time of vaccination for infectious bovine rhinotracheitis virus or IBRV) and at an average age of 224 d (60 d postvaccination)....

Winter supplementation and delayed weaning of an autumn calving beef herd under western Oregon conditions

Creator:: Buehner, Heidi Renata
Abstract:: Two management systems were evaluated in terms of the effects on cow condition score and body weight changes and calf growth rates. The management systems evaluated were winter supplementation of energy, winter creep feeding and delayed weaning. The calves used in this study were born in September and October of...
