Evaluation Of Novel Litter Amendments For Use In The Commercial Broiler Industry, Jorge A. Urrutia
Theses and Dissertations
Poultry litter amendments (LA) are commonly used to maintain good litter quality; the most common ones; are acidifiers. However, concern over the lifespan of LA acidifiers (d) and corrosive nature revealed a need for alternative LA. Products of interest include biochar (BC), superabsorbent polymers (SAPs), and alum mud (AM). Experiment 1 was a screening study (n=17 treatments, no birds) conducted to determine the optimal application rate/method of BC, SAPs, and AM vs.commercial LA and a control. Most SAPs treatments measured metrics may be similar (i.e., bacteria, water activity) or better (pH) vs. commercial LA (PLT). High inclusions of novel LA …
Molecular, Somatic, And Performance Characteristics Of Broilers Exhibiting Woody Breast Myopathy, And The Effects Of Dietary And Challenge Intervention Strategies, Linan Jia
Theses and Dissertations
Woody breast (WB) is a meat quality problem that has caused significant economic losses for the poultry industry. Ross × Ross 708 chicks were randomly assigned to a 3 (diet) × 2 (cocci challenge) × 2 (sex) factorial arrangement of treatments. The three diets included the control diet (corn-soybean meal basal diet), antibiotic diet (basal diet + 6.075 mg bacitracin /kg feed), and probiotic diet (basal diet + 2.2 × 108 CFU Bacillus subtilis PB6 /kg feed). Birds in the cocci challenge treatment group received 20 × the live cocci vaccine as an inoculum on d 14. Growth performance and …
