Nutritional Management of Beef Cows During Late-Gestation to Enhance Offspring Productivity

Creator:

Marques, Rodrigo Da Silva

Abstract:

Two experiments evaluated nutritional management of late-gestating beef cows to enhance offspring productivity. The objective of experiment 1 was to evaluate the effects of organic and inorganic Cu, Mn, Zn, and Co supplementation to beef cows during late-gestation on performance and physiological responses of the offspring. The objective of experiment...

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...

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...

The fatty acid composition of certain bovine tissues

Creator:

Thompson, Robert Charles, 1927-

Abstract:

In this study subcutaneous, inter- and intramuscular fats from 42 Hereford steers were analyzed for their fatty acid composition using gas-liquid chromatography. The same tissues were analyzed from one pair each of identical twins of Angus and Shorthorn breeding. Muscle and liver lipids from these latter four animals were fractionated...

Dissertation
Influence of supplement composition on utilization of low-quality, cool-season forages by beef cattle

Creator:

McGuire, Dustin L.

Abstract:

Two studies were conducted to evaluate the influence of supplement composition on intake and digestibility of a low-quality (< 6% CP), cool-season forage, as well as cow performance. Treatments included a non-supplemented control (CON), corn (approximately 8% CP), corn and urea (LU = corn + 0.09 mg/kg BW urea, approximately...

Masters Thesis
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...
