The Effect Of Copper And Zinc Source On Pre-Weaning Performance Of Cows, Health And Performance Of Suckling Calves, And Post-Weaning Feedlot Performance, Carcass Composition, And Meat Quality Of Calves, Jesse Fulton

Electronic Theses and Dissertations

During gestation an elevated level of nutrient intake is required by the cow in order to meet the requirements of the maturing fetus and if these requirements are not met, changes in fetal development can occur. However, little is understood about the effects of gestational manipulation of specific nutrients, such as minerals, on progeny growth, performance and carcass traits. Previous research supports the hypothesis that minerals provided in an organic form should be more soluble and readily available to the body for absorption. Therefore the objectives of this study were to determine if source of gestational and post-natal Cu and …

Effect Of Weaning Date On Performance Of Beef Cows, R. J. Pruitt, P. A. Momont

South Dakota Beef Report, 1994

Records from 92 mature crossbred cows calving in March and April were used to determine the effect of weaning calves 40 days earlier than the traditional weaning time on cow weight change, body condition, and reproductive performance. When calves were weaned early (September 14 versus October 231, their dams gained more weight from September 14 to early December and had higher body condition scores in December than the dams of later weaned calves. The two nutritional treaments imposed after calving were important in explaining the effects of earlier weaning on cow reproductive performance. For cows that were fed grass hay …

Serum D-Β-Hydroxybutyrate And Urea Nitrogen As Indicators Of Beef Cow Nutritional Status, P.A. Momont, R.J. Pruitt, R.H. Pritchard

South Dakota Beef Report, 1988

Mature Simmental x Angus crossbred cows were fed differing levels of nutrition before and after calving (mid-March to early May) to determine if blood serum levels of d-β-hydroxybutyrate (BHB) and urea nitrogen (SUN) could be used as indicators of nutritional status. Visual condition scores and condition score change were used as subjective appraisals of cow nutritional status. BHB levels prior to calving were elevated for cows close to calving and those carrying male fetuses. SUN levels prior to calving were higher for thin cows that were losing body condition. If on a low plane of nutrition after calving, BHB values …
