Contemporary light sources and their impact on the discoloration and oxidation of fresh beef products
(University of Missouri--Columbia, 2017)Discolored fresh meat products in a retail setting are often perceived negatively by consumers when making purchasing decisions. Prolonging fresh meat color is critical for the retail industry in regard to sales and consumer ... -
Effect of preovulatory follicle size on cumulus cell and follicular wall transcript abundance in beef cows
(University of Missouri--Columbia, 2017)Gonadotropin releasing hormone (GnRH)-induced ovulation of small dominant follicles decreased pregnancy rates and increased late embryonic/fetal mortality in postpartum beef cows, which could be caused by inadequate oocyte ... -
Envelopment of a fibroblast growth factor 21 assay
(University of Missouri--Columbia, 2017)Obesity and diabetes play a major role in many diseases prevalent in our current society. Fibroblast Growth Factor 21 (FGF21) is a recently discovered hormone that has potential for therapeutic treatment of obesity and ... -
The impact of fescue toxicosis & T-Snip score on post-weaning beef cattle performance
(University of Missouri--Columbia, 2017)It is well known that fescue toxicosis has a negative impact on cattle productivity. These studies were conducted to evaluate the effects of fescue toxicosis on post-weaning beef steers, as well as the impact of T-Snip ... -
Optimizing beef cattle performance using rumen-protected lysine supplementation in diets balanced for predicted amino acid and effective energy requirement
(University of Missouri--Columbia, 2017)The objectives of these experiments were to determine the bypass value of rumen-protected lysine and performance responses of beef cattle fed encapsulated lysine. During experiment 1 singe-flow continuous culture fermenters ... -
Phosphorus digestibility of corn and soybean meal (SBM) in broilers : in search of a consistent and reliable model to quantify individual ingredient contribution
(University of Missouri--Columbia, 2017)Two experiments were conducted to determine true digestibility of Phosphorus (P) in feed ingredients commonly in commercial broiler diets. A second objective was to determine if the true digestible P values of corn and ... -
Potential diagnostic methods and nutritional changes to combat bovine respiratory disease in receiving cattle
(University of Missouri--Columbia, 2017)Bovine respiratory disease (BRD) accounts for up to 70 percent of health disruptions and $500 million in associated medical costs and production losses, thus receiving considerable attention from cattle health personnel ... -
Transgenerational effects of in utero heat stress on reproduction in pigs
(University of Missouri--Columbia, 2017)Seasonal infertility caused by high ambient temperatures and humidity during the summer months can have negative effects on the reproduction of female swine. These conditions may cause heat stress leading to large economic ...
