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)...

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...

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...

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...

The NRF2-controlled Antioxidant Response, Alternative Forages, and Selenium supplementation for Improving Ruminant Productivity and Health

Creator:: Ford, Hunter
Abstract:: Oxidative dysfunction can affect dairy animals during periods of heightened stress, particularly during the transition from pregnancy to lactation and during diseases, such as intramammary infection (IMI), and can contribute to increased inflammation, immune dysfunction, and cell death. As such, methods for ameliorating oxidative stress and restoring redox regulation may...

Molecular Nutrition in Dairy Cows: Modulation of Peroxisome Proliferator-Activated Receptors through Nutrigenomic Approaches

Creator:: Busato, Sebastiano
Abstract:: Nutrigenomics is a branch of nutrition that seeks to elucidate the relationship between dietary components and expression of genes. Certain bioactive compounds present in the diet have the potential to modulate transcription of genes through their interactions with ligand-dependent nuclear receptors, a series of transcriptional regulators capable of sensing intracellular...

Pasture Production and Lamb Growth from Dryland Hill Pastures in Western Oregon

Creator:: Gultekin, Yunus
Abstract:: Pasture legumes that persist under challenging agro-ecological conditions are crucial to ensure high lamb growth rates in dryland pastures. Pasture and lamb production from white clover (TF-Whc), birdsfoot trefoil (TF-Bft), balansa clover (TF-Bc) and subterranean clover (TF-Sc) planted with tall fescue either as binary mixtures or as a diverse combination...

Reconstruction and Validation of the Integrated Diagnostic SystEm for DAiry Cow WeLfare (IDEAL) to Assess Real-time Animal Well-being on Confined and Grazing Dairy Farms

Creator:: Krueger, Angela K.
Abstract:: Animal welfare is an essential component of agricultural production and animal use in teaching and research. However, defining animal welfare is intrinsically difficult because of how history and societal values and perceptions have shaped the term. Animal welfare encompasses three main ideas: physical well-being, normal affective/emotional states, and the ability...
