Effects Of Dietary Copper, Zinc And Manganese Source And Level On The Acute Inflammatory Response Of Broilers, Chelsea Ellington
Effects Of Dietary Copper, Zinc And Manganese Source And Level On The Acute Inflammatory Response Of Broilers, Chelsea Ellington
Graduate Theses and Dissertations
Trace minerals, particularly copper, zinc and manganese, play a role in ensuring optimal immune function. To examine the effects of diets containing different levels and sources of trace minerals on the inflammatory response, Cobb 500 broilers were fed four experimental diets containing 5 mg/kg Cu and 45 mg/kg of Zn and Mn or 10 mg/kg Cu and 90 mg/kg Zn and Mn in either the sulfate or hydroxychloride form. When the broilers were 5 weeks of age, 16 μg of lipopolysaccharide (LPS) was injected into the pulp of growing feathers (GF; 16 GF per chicken; 1 μg LPS per GF). …
Prediction And Evaluation Of Breast Myopathy, Barbara De Almeida Mallmann
Prediction And Evaluation Of Breast Myopathy, Barbara De Almeida Mallmann
Graduate Theses and Dissertations
Broiler breast myopathies, including woody breast, white striping, and spaghetti breast, negatively impact the industry. Therefore, evaluation, prediction, and frequency of these muscle abnormalities on modern birds are important for decision making. Modern broilers are not highly active and often sit with the breast of the bird resting on the floor. Therefore, the first experiment was to promote bird movement and explore the impact on the breast myopathies. The movement was stimulated by human interaction (walking through pen) and higher light intensity so that birds walked around the pen more often throughout the day. The control group had normal low …
Whole Egg Consumption Impairs Insulin Sensitivity In Rat Model Of Obesity And Type 2 Diabetes, Cassondra J. Saande, Megan A. Steffes, Joseph L. Webb, Rudy J. Valentine, Matthew J. Rowling, Kevin Schalinske
Whole Egg Consumption Impairs Insulin Sensitivity In Rat Model Of Obesity And Type 2 Diabetes, Cassondra J. Saande, Megan A. Steffes, Joseph L. Webb, Rudy J. Valentine, Matthew J. Rowling, Kevin Schalinske

Background: The literature regarding the relation between egg consumption and type 2 diabetes (T2D) is inconsistent and there is limited evidence pertaining to the impact of egg consumption on measures of insulin sensitivity. Objective: The objective of this study was to investigate the effect of dietary whole egg on metabolic biomarkers of insulin resistance in T2D rats. Downloaded from https://academic.oup.com/cdn/advance-article-abstract/doi/10.1093/cdn/nzz015/5374517 by Iowa State University user on 28 March 2019 Methods: Male Zucker diabetic fatty rats (n=12; 6 wk of age) and their lean controls (n=12; 6 wk of age) were randomly assigned to a casein- or whole egg-based diet. At …

Immunomodulation of the immune system by stimulating or suppressing one or both arms, is an emerging concept driven by the understanding of the host defense system. In particular, the gastrointestinal tract (GIT) functions not only as a site for digestion and absorption of nutrients but also acts as a metabolic and immunological organ. This serves as a barrier against abnormal presentation of luminal constituents, caused by dysfunctional intestinal epithelial barrier, to the mucosal immune system. Invasion by pathogens in the case of disease or stress or a massive influx of commensal bacteria overcomes the defensive mechanisms, resulting in the full …
Microalgae And Zinc Source Supplementation Of Broiler Breeder Diets Affects Broiler Breeder Skeletal Development And Reproduction With Transgenerational Impacts On Offspring Performance And Skeletal Characteristics, Marquisha A. Paul
Theses and Dissertations--Animal and Food Sciences
Leg problems and disorders are of major concern for the poultry industry and animal welfare. Previous studies suggest that it may be possible to improve skeletal characteristics through nutrition. Omega-3 fatty acids, including Docosahexaenoic acid (DHA), are essential nutrients and are known to play an important role in bone tissue development. FORPLUS™ (Alltech, Inc.) is an unextracted, whole-cell microalgae (Aurantiochytrium limacinum CCAP 4087/2) that contains 64% fat and 16% DHA. Zinc (Zn) is a trace element and essential nutrient for growth and skeletal development. Bioplex® Zn (Alltech, Inc.) is a Zn proteinate that has been shown to be …
