Improvement Of Nutrient Utilization Efficiency, Ruminal Fermentation And Lactational Performance Of Dairy Cows By Feeding Birdsfoot Trefoil, Rachael G. Christensen
Improvement Of Nutrient Utilization Efficiency, Ruminal Fermentation And Lactational Performance Of Dairy Cows By Feeding Birdsfoot Trefoil, Rachael G. Christensen

Condensed tannins (CT) are compounds that have shown potential to reduce the environmental impact of dairy farming waste products. In two live animal studies and a continuous culture study, it was hypothesized that feeding birdsfoot trefoil (Lotus corniculatus, BFT), a CT-containing legume, would improve nutrient utilization, milk, and component yield of dairy cows compared with feeding alfalfa hay or grass pasture in two studies, while feeding BFT forage would decrease methane production and improve rumen fermentation in addition to concentrate supplementation was the hypothesis of the third study. Reduction in milk urea nitrogen (MUN) and …

Consumer evaluation, proximate data, Warner-Bratzler shear force (WBSF), fatty acid (FA) composition and volatile compounds were analyzed from the ribeye steaks (LT) finished on conventional feedlot (FL) and forages, including a perennial legume, birdsfoot trefoil (BFT; Lotus corniculatus), and a grass, meadow brome (Bromus riparius Rehmann, Grass). Representative retail forage (USDA Certified Organic Grass-fed, COGF) and conventional beef (USDA Top Choice, TC) were investigated (n = 6) for LT. Additionally, the effects of diet on round (GM) and chuck (TB) muscles FL, BFT and Grass were explored. Forage-finished beef was less liked in most of the affected …

Growth Performance, Ruminal Fermentation Characteristics, And Economic Returns Of Growing Beef Steers Fed Brown Midrib, Corn, Silage-Based Diet, Christopher Scott Saunders

Sustainable beef production is extremely important to the beef cattle industry. Sustainability influences the environment, overall profits, and public concerns. One
factor that influences sustainability is the composition of cattle feed. This study compared conventional corn silage (CCS), which is most commonly used in beef steer feed, to brown midrib corn silage (BMR). Steers fed the two different diets were compared to determine differences in the areas of growth/animal performance, ruminal fermentation (digestion), and economic returns. The study included 24 beef steers randomly assigned to one of two treatment groups. Treatment groups were a total mixed feed ration that included …
Development Of Genetic Goat And Hamster Models Of Atrial Fibrillation And Long Qt Syndrome; And Genetic Hamster Models Of Middle East Respiratory Syndrome, Dane A. Rasmussen
Development Of Genetic Goat And Hamster Models Of Atrial Fibrillation And Long Qt Syndrome; And Genetic Hamster Models Of Middle East Respiratory Syndrome, Dane A. Rasmussen

Atrial fibrillation (AF) and long QT syndrome (LQTS) are potentially lethal heart rhythm disorders that can be caused by mutations in the potassium channel gene KCNQ1. Middle East Respiratory Syndrome (MERS) is a viral infection with the potential to replicate the devastating effects of the SARS outbreak in 2003. All three of these diseases are in need of genetic animal models.
To address these needs, my thesis project focused on the development of genetic goat and hamster models of AF and LQTS, and genetic hamster models of MERS. Because of the goat’s similar organ size/physiology and the hamster’s similar lipid …
