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...

Growth and carcass merit of purebred Jersey steer calves finished on grain-based diets at two different energy levels

Creator:: Tschida, Garrett L.
Abstract:: Purebred Jersey steers are often overlooked for beef production due to the perceived poor growth and production. Currently dairy persons marketing their steer offspring are receiving minimal compensation due to lack of demand by beef feeders and a saturated veal market. Twenty purebred Jersey steers were used to evaluate lifetime...

Locally grown alternative feed ingredients in turkey diets

Creator:: Sulaiman, Kurdman Mohammed Ali
Abstract:: In recent years, small poultry producers have been interested in finding an alternative for corn and soybean for a variety of reasons. Health concerns related to either naturally occurring isoflavones (phytoestrogens) or their genetically modified organism (GMO) status are the primary considerations behind this trend. Secondly, the recent high prices...

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...

Lipid Metabolism and the Broiler Chicken : Effect of Dietary n-3 Fatty Acids

Creator:: Head, Brian A.
Abstract:: In broiler chickens, hepatic lipid metabolism plays a significant role in whole body and muscle fatty acid (FA) incorporation. Flax seed is a rich source of α-linolenic acid and can be used to increase n-3 FA in poultry meat. Previous studies have shown that flax seed in combination with carbohydrase...

Use of herbal feed additives in poultry feeding

Creator:: Nix, Kathryn
Abstract:: The use of an antibiotic as a growth promoter (AGP) began in the 1940’s with the discovery of growth responses from Streptomyces aureofaciens in the monogastric diet. However, resistance and residue problems have increased the negative consumer perception of growth promoting antibiotic use in animal diets. Although no direct link...

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...

Maternal diet and essential fatty acid metabolism in progeny chickens

Creator:: Bullock, Cheri Jean
Abstract:: During the 21 day incubation period, the fertile egg provides nutrients such as fatty acids for energy and polyunsaturated fatty acids (PUFA) for membrane synthesis to the developing chick. The hypothesis tested in the present study is that the type of PUFA fed to the breeder hen can alter tissue...

The effects of differing hazelnut concentrations in hog finishing rations with respect to pork shelf-life and fatty acid composition

Creator:: Parker, Nathan B.
Abstract:: Commercial hog diets in the United States commonly contain lipid sources high in polyunsaturated fatty acids, most notably linoleic acid (18:2). This may result in greater deposits of linoleic acid in pork adipose tissue, contributing to an increased potential for lipid oxidation, high n-6/n-3 fatty acid ratio and increased fat...
