  • 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...

  • Enzyme Supplementation of Layer Hen Diets Containing Whole Flaxseed to Increase n-3 Fatty Acids in Chicken Eggs

    Creator:
    Westbrook, Lindsay A.
    Abstract:
    Flaxseed is a rich source of alpha-linolenic acid (ALA). Feeding laying hens flax seed can increase n-3 fatty acids content (FA) in eggs, thus increasing human intake of n-3 FA. However, non-starch polysaccharides (NSP), which decreases digestibility of dietary lipids and proteins. Addition of carbohydrase enzymes to flax-based layer diets...

  • 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...

  • Broiler Chicken Meat Quality and Lipid Composition as Influenced by type of Retail Label and Diet Composition

    Creator:
    Khan, Ibrahim A.
    Abstract:
    The objectives of the current study were 1) to evaluate the nutritional composition of chicken breast meat labelled as organic and non-organic, and 2) to determine the effect of microalgae and methionine supplementation on meat quality, the incidence of white striping, and muscle pathology in broilers. Two experiments were conducted...
