Mycotoxicoses in domestic livestock: toxicity of ergot alkaloids in domestic poultry and fusariotoxins in beef cattle

Creator:: Roberts, Heaven Le A.
Abstract:: Mycotoxins are food-borne toxins produced by molds which are commonly found on animal feeds of economic significance. Toxic doses of these compounds vary widely across livestock species, and even within a species when considered across all stages of development and production. This variation is due to the wide range of...

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...

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 strategies to improve the reproductive performance of beef females

Creator:: Cappellozza, Bruno Ieda
Abstract:: In the first set of studies, 2 experiments evaluated the influence of supplement composition on ruminal forage disappearance, performance, and physiological responses of Angus × Hereford cattle consuming a low-quality, cool-season forage (8.7 % CP and 57 % TDN). In Exp. 1, 6 rumen-fistulated steers housed in individual pens were...

Himalayan blackberry (Rubus armeniacus) and English ivy (Hedera helix) response to high intensity-short duration goat browsing

Creator:: Ingham, Claudia S.
Abstract:: The goal of this dissertation is to examine the effectiveness of high intensity-short duration goat browsing for the control of Himalayan blackberry (Rubus armeniacus) and English ivy (Hedera helix), two widespread noxious weeds in the Pacific Northwest. The effects of goat browsing on Himalayan blackberry vigor, as quantified by densities...

The ability of a yeast-derived cell wall preparation to minimize toxic effects of high-alkaloid tall fescue straw in beef cattle

Creator:: Merrill, Melissa L.
Abstract:: Two experiments were conducted to evaluate the influence of a yeast-derived cell wall preparation (YCW) on forage intake and digestibility, ruminal fermentation characteristics, serum prolactin and prolactin stores, and milk production in beef cattle consuming high-alkaloid tall fescue straw. In Exp. 1, 16 Angus x Hereford ruminally cannulated steers (200...

The effect of prepartum anionic diets on cortisol, adiponectin, and tumour necrosis factor-α expression at varying levels of body mass index in preparturient dairy cows: implications for insulin resistance

Creator:: Puntenney, Steven B.
Abstract:: Twenty-six Holstein and 18 Jersey multiparous cows in a randomized block design were assigned by calving date and breed to a non-anionic prepartum diet (CTRL) or a treatment diet containing a commercial anionic salt supplement (Animate®). Control and treatment diets were formulated to a dietary anion-cation difference (DCAD) of 21.3...

Hemorrhagic bowel syndrome in dairy cattle and efficacy of feed additive in stimulating immune response in livestock

Creator:: Wang, Yong-Qiang
Abstract:: Hemorrhagic bowel syndrome (HBS) is a devastating disorder affecting high producing dairy cattle. As an important emerging disease (Animal and Plant Health Inspection Service, 2003), HBS is now estimated to account for > 2% of the deaths of dairy cattle (Kirkpatrick et al, 2001). However, little is known about the...

Effect of prepartum anionic supplementation on periparturient feed intake and behavior, health and milk production

Creator:: DeGroot, Michael Alan
Abstract:: Our objectives were to determine if dietary cation-anion difference (DCAD) and source of anions influence periparturient feed intake and milk production, and to characterize feeding behavior of dairy cattle during the transition period. Diets differed in DCAD (cationic or anionic) and anionic supplement (BioChlor®, Fermenten®, or anionic salts), and were...

Influence of protein supplementation frequency on cows consuming low-quality forage : performance, grazing behavior, and variation in supplement intake

Creator:: Schauer, Christopher Scott
Abstract:: Our objective was to determine the influence of CP supplementation frequency (SF) on cow performance, grazing time, distance traveled, maximum distance from water, cow distribution, DMI, DM digestibility, harvest efficiency (HE), percentage of supplementation events frequented, and CV for supplement intake for cows grazing low-quality forage. One hundred-twenty pregnant (approx....
