Assessment Of Meat Quality Attributes Of Four Commercial Broiler Strains Processed At Various Market Weights, Ashleigh Jo Mueller

Graduate Theses and Dissertations

As the demand for poultry meat continues to grow, the industry is challenged with how to meet these needs of consumers. The growth rate of broilers is continuously improving in order to increase production efficiently resulting in greater yields and an increase in product to satisfy consumer needs. However, the industry has seen an increase in quality issues of the meat as growth rates and growth periods continue to increase. The objective of this study was to evaluate the effect of various strains (standard and high-yielding) and target weights on meat quality attributes such as pH, water holding capacity (WHC), …

Characterization Of Growth Patterns And Meat Quality Characteristics Of Four Commercial Broiler Strains In Small Bird And Large Bird Programs In The United States, Clay Johnny Maynard

Graduate Theses and Dissertations

Through current trends in animal protein consumption, the United States poultry industry has seen a drastic rise in production and popularity. Over the last few decades, poultry meat has surpassed both beef and pork production to become the most widely consumed animal protein. This rise may be accredited to an increased transition to more health-conscious consumers. As more consumers purchase poultry as a lean source of protein, the need for a superior quality product is of great interest to poultry integrators.

Relationships between commercial broiler lines have been well documented in previous years, but constant and intensive genetic selection in …

Effects Of Supplementing Crystalline L-Valine And L-Isoleucine And A Novel Threonine Biomass In Reduced Crude Protein Diets Fed To Broilers, Derrell Trevor Lee

Graduate Theses and Dissertations

Poultry nutritionists continue to identify methods to lower feed price without compromising broiler growth performance, processing yields, or animal well-being. A common approach is to reduce dietary crude protein (CP), the second most expensive component in a broiler diet. Subsequently, reducing CP will reduce the inclusion levels of intact protein sources (e.g., soybean meal [SBM]), which can be accomplished by supplementing individual amino acids (AA). This methodology not only reduces diet cost, pending if feed-grade AA are more economical, but can contribute to improving broiler health and environmental sustainability. Therefore, two experiments were conducted to evaluate individual feed-grade AA in …

Meat Quality Of Broiler Breast Fillets With White Striping And Woody Breast Muscle Myopathies, Vishwesh Vijay Tijare

Graduate Theses and Dissertations

The global poultry industry has been faced with emerging broiler breast meat quality issues known as white striping and woody breast. Two experiments were conducted to evaluate effects of white striping and woody breast hardness on meat quality traits in broiler breast fillets. Birds were processed at 8 wk (Exp.1) and at 6 and 9 wk of age (Exp.2), whereas deboning was carried out at 4 and 2 h postmortem in Exp.1 and 2, respectively. Fillets were categorized as: normal for both white striping and woody breast (NORM); mild for white striping and woody breast (MILD); severe for white striping …
