Drought Stressed Soybean Supplementation for Beef Cows
(Oklahoma State University, 2005-07-01)Three experiments involving gestating and lactating beef cows were conducted to determine the effects of winter supplementation with whole or rolled drought stressed soybeans (DSSB). Gestating spring calving cows grazed ... -
Effect of diet quality on dry matter intake, gene expression, greenhouse gas emissions, and production measures in mature beef cows
(2021-07)The purpose of this research was to examine the effect that diet quality had on dry matter intake, gene expression, greenhouse gas emissions, and production measures in gestating, mature Angus beef cows. Two experiments ... -
Maintenance energy requirements, postpartum reproduction, and ruminal temperature at parturition and estrus of beef cows
(2009-05)Scope and Method of Study: Angus x Hereford cows were used to determine the effects of postpartum weight gain (WG) and treatment with bovine somatotropin (bST) on concentrations of hormones in plasma and calf growth. Cows ... -
Maintenance Energy Requirements, Ruminal Temperature, Walking Activity, and Plasma Concentrations of IGF-I, Thyroxine, and Triiodothyronine of Gestating Beef Cows
(Oklahoma State University, 2011-07-01)Three experiments with spring calving, Angus cows (Exp. 1, n = 40; Exp. 2, n = 32; Exp. 3, n = 32) were conducted to determine the effects of maintenance energy requirement (MR) on plasma concentrations of insulin-like ...
