The Effects of a Dietary Immunomodulatory Supplement on the Immune-Metabolic Axis in Growing Beef Cattle

Creator:: Armstrong, Shelby A.
Abstract:: To evaluate the immunologic and metabolic effects of OmniGen-AF® (Phibro Animal Health corporation, Quincy, IL; OG) supplementation in growing beef cattle, we designed three studies using replacement beef heifers (8.5 and 10.5 months of age) and steers supplemented across backgrounding, transition, and finishing periods. In Study 1, the effect of...

Nutritional and management strategies of trace mineral supplementation for beef cattle

Creator:: Puerto Hernandez, Gracia Maria
Abstract:: Two studies evaluated the mineral status of supplemented beef cattle over two different methods of supplementation. The objective of study 1 was to evaluate the mineral status at weaning and subsequent post-weaning performance of calves supplemented prior to weaning, with limited-fed supplements fortified with trace minerals (Cu, Se, and Zn)...

Effects of selenium supplementation during different trimesters of pregnancy on non-specific humoral immunity of pregnant beef cows and persistence of antibodies in their newborn calves

Creator:: Thompson-Hernandez, Ian
Abstract:: Immunosuppression during the periparturient period leads to increased susceptibility to infectious diseases in beef cows. Newborn calves rely on passive transfer of antibodies from their mothers at birth for protection against diseases in the first two months of age. It is unknown if supranutritional Se supplementation of cows during pregnancy...

Reproductive Effects of PG-600 Administration in Ewes

Creator:: Habeeb, Hayder
Abstract:: Sheep are seasonally polyestrus, which means they do exhibit estrus and ovulation during the short daylight (breeding season) and do not during the long daylight (nonbreeding season). To stimulate the ewes to ovulate during the nonbreeding season, various hormonal treatments have been used. PG-600 contains both equine chorionic gonadotropin and...

Management Strategies to Improve Immune Function and Performance of Feeder Cattle

Creator:: Lippolis, Katana D.
Abstract:: Three experiments evaluated the effects of different management strategies on immune function and performance of feeder cattle. The objective of experiment 1 was to compare the effects of anticipating, delaying, or vaccinating against Bovine Respiratory Disease (BRD) at the time of weaning and feedlot entry on growth, DMI, and plasma...

Prevalence of Deficiency and Relationship of Management Practices to Vitamin E and Selenium Status in Horses

Creator:: Pitel, Mariya O.
Abstract:: Deficiency of selenium (Se) or alpha-tocopherol (E) creates serious health issues in horses. This study evaluated owner supplementation practices and their efficacy at preventing deficiency in a large population of horses. In addition, common clinical signs of horses presenting to a referral institution who had Se and E testing performed...

Nutritional Management of Beef Cows During Late-Gestation to Enhance Offspring Productivity

Creator:: Marques, Rodrigo Da Silva
Abstract:: Two experiments evaluated nutritional management of late-gestating beef cows to enhance offspring productivity. The objective of experiment 1 was to evaluate the effects of organic and inorganic Cu, Mn, Zn, and Co supplementation to beef cows during late-gestation on performance and physiological responses of the offspring. The objective of experiment...

Housing Chickens: How Much Space is Enough?

Creator:: Bradley, Emily D.
Abstract:: The stocking density for chickens can have major impacts on their health and welfare. There is no single correct answer for how many chickens you can house in a specified area, as it depends on the quality of housing. Chickens can tolerate a higher stocking density without major health concerns...

Possible Autocrine/Paracrine Action of Progesterone in the Ovine Corpus Luteum

Creator:: Smallman, Mary A.
Abstract:: The objective of the present research was to determine, by use of the progesterone receptor antagonist RU-486, whether progesterone by autocrine/paracrine action suppresses phosphatidylinositol hydrolysis, and thus, the production of prostaglandin F2a during the midluteal phase of the estrous cycle in ewes. Two experiments were performed. Experiment 1 consisted of...

Learning to Care : Applied Ethics for Improving Farmed Animal Welfare

Creator:: Zarajczyk, Katie MaryRuth
Abstract:: This thesis seeks to explore how an ecofeminist lens is currently the most useful approach for improving farmed animal welfare. Through examining Western conceptions of non-human animals, I seek to shed light upon the inconsistent treatment of domestic species. Species that are dependent upon us deserve, at a minimum, not...
