Feed Conditioning Effects On Enzymes, Amino Acids, And Subsequent Broiler Performance, Elizabeth Ann Lynch
Feed Conditioning Effects On Enzymes, Amino Acids, And Subsequent Broiler Performance, Elizabeth Ann Lynch
Graduate Theses, Dissertations, and Problem Reports
There are many things that can be done to improve broiler performance including, but not limited to, pelleting, proper Lys inclusion, and exogenous enzyme supplementation. Pelleting has the ability to improve feed form, reduce wastage, improve bird performance metrics, and decrease pathogens within the feed. Pathogen reduction can be further reduced by hygienic pelleting practices which include an increase in temperature or retention time within a conditioner or hygieniser. However, hygienic pelleting can degrade valuable AA and enzymes (more specifically for the current thesis research Lys and phytase) and make them unavailable to the animal. Supplementing Lys to account for …

The Effects Of Feed Additives And The Use Of A Novel Wood Boiler Heat Exchanger On Litter Quality, Broiler Performance, And Immune Status, Victoria Ayres
Graduate Theses, Dissertations, and Problem Reports
Experiments were conducted to investigate the effects of varying feed ingredients and heating systems on boiler performance metrics. Chapter Two investigated the effects of two corn-expressed phytases, differing in enzyme concentration within the grain (3,000 or 9,677 FTU/g), on broiler performance and tibia mineralization, when used as a component in pelleted feed. Dietary treatments included a positive control (PC), with industry-recommended levels of calcium and phosphorous, and a negative control (NC), lower in calcium and non-phytate phosphorous. Six diets containing corn-expressed phytase at high or low grain concentrations, formulated to 3,000, 6,000, or 9,000 FTU/kg, were …
