Relationships Among Beef Cow Productivity Traits And Single Nucleotide Polymorphisms In The Bovine Heat Shock Protein 70 Gene, Ashley Finney
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 …
Hair Shedding Scores Relating To Maternal Traits And Productivity In Beef Cattle, Ashton Williams
Hair Shedding Scores Relating To Maternal Traits And Productivity In Beef Cattle, Ashton Williams
Animal Science Undergraduate Honors Theses
The objectives of this study were to measure how quickly cattle shed their winter coat in the sub-tropical climate of Arkansas. As well as, to understand the role age may play on cattle shedding efficiency in spring and summer months, in conjunction with the relationship between mother hair coat and calf sex. Angus based commercial beef cattle (n = 224) were observed over a five-month period in 2012. Once monthly, at approximately 28-day intervals, cattle were evaluated for shedding on a scale from 1 to 5. A score of 5 indicated the cow/heifer had a full winter coat and a …
