Effects Of Supplemental Whole Cottonseed On Weaned Calf Production, Zachary Debord

Mahurin Honors College Capstone Experience/Thesis Projects

This study compared the effect of supplemental whole cottonseed in a weaned calf ration on cattle productivity. Feed is the main cost for livestock production. Whole cottonseed supplementation may increase production and reduce the cost of gain for the ration. During the study, 18 beef calves were weaned and split into two groups and fed, with and without WCS, for 50 days to determine the effect of supplemental whole cottonseed. Productivity was determined by measuring average daily gains for each group and comparing cost of gain for each ration. It was determined that WCS did increase productivity of weaned calves …

Relationships Among Beef Cow Productivity Traits And Single Nucleotide Polymorphisms In The Bovine Heat Shock Protein 70 Gene, Ashley Finney

Animal Science Undergraduate Honors Theses

When eukaryotes are exposed to stressors such as heat, toxins, and low oxygen levels, heat shock proteins (HSPs) are synthesized to maintain normal cellular function within the body. Single nucleotide polymorphisms in the heat shock protein 70 (Hsp70) gene have been associated with calving percentage, and Julian calving date in spring-calving crossbred Brahman cows (Rosenkrans, et al., 2010). Our objective was to determine associations between previously identified polymorphisms in the promoter region and coding sequence of the bovine Hsp70 gene and beef cow efficiency. We evaluated productivity traits, including Julian calving date and calving rates, of fall-calving cows at each …

Economic And Environmental Effects Of Switchgrass Production On A Representative Cow-Calf Farm In Middle Tennessee, Hanna Leah Watts

Masters Theses

The purpose of this research was to evaluate the economic tradeoffs and land use dynamics of incorporating switchgrass into the farm plan of a representative middle Tennessee cow-calf operation. A net revenue simulation and multi-year mathematical programming model was used to find the optimum mix of switchgrass and cow-calf enterprises that will maximize whole farm net revenues over 30 years on a representative middle Tennessee beef farm under both average and above average management. Land use changes predicted by the mathematical programming model were used to assess the carbon change associated with incorporating, or transitioning to, switchgrass production.

Influence Of Advance In Season On Nutritive Value Of Forage Consumed By Cattle Grazing Western Nebraska Native Range, C. L. Streeter, D. C. Clanton, O. E. Hoehne

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The purpose of this study was to determine the influence of the advance in season on the nutritive value of forage consumed by cattle grazing western Nebraska summer range. Eleven digestion trials were conducted during the summer grazing season of two consecutive years.

The Relations Of Vegetative Composition And Cattle Grazing On Nebraska Range Land, T. E. Brinegar, F. D. Keim

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The objectives of the studies reported in this paper were: (1) to obtain an analysis of the vegetation in tall and short grass range lands, (2) to observe the activities of cattle on the range, and (3) to determine the effects of grazing upon vegetation.

On The Nature And Cause Of "The Walking Disease" Of Northwestern Nebraska (Necrobiosis Et Cirrhosis Hepatis Enzootica), L. Van Es, L. R. Cantwell, H. M. Martin, J. Kramer

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The "walking disease" of Northwestern Nebraska is essentially an enzootic necrobiosis and cirrhosis of the liver due to a toxic agent and does not materially differ from similar disorders occurring in other regions or countries. The disease affects horses and cattle but it is most commonly encountered in the former. The disease in all its clinical and pathological manifestations may be reproduced with the utmost fidelity by the feeding with plants of Senecio riddellii.

The Abortion Problem In Farm Live Stock, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

This casting out of a dead or at least abnormal fetus we call abortion. It constitutes the culminating accident in a process set into motion by disease or injury. To the breeder it is its most conspicuous feature, and it's more or less constant occurrence among live stock warrants us to speak of the abortion problem. It is the purpose of this publication to lay before our Nebraska breeders such information on the subject as can be gathered from the more recent literature and from observations in the field and the laboratory.
