Reference number : GC-2017-Q4-00919, amendment number : , agreement type : G, recipient legal name : Kiarie, Elijah (University of Guelph), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Engage Grants for universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : Profitability and sustainability are very important considerations for our poultry customers. The poultry sector in Canada is in_x000D_
transition because of pressure to adopt alternative housing for layers (litter floors, cage-free) and to reduce the use of subtherapeutic antimicrobial growth promoters (AGP). Because of these regulatory and social pressures our poultry customers are_x000D_
looking for solutions to minimize use of AGP and to decrease environmental impact particularly ammonia gas emissions in poultry_x000D_
houses which have detrimental effects on birds and humans. Dietary crude protein concentration has a significant impact on the_x000D_
intestinal microbiota, both qualitatively and quantitatively. For example, several studies indicate that high protein diets with excess_x000D_
and unbalanced amino acid profiles increase the concentrations of pathogenic bacteria and toxic metabolites in the gut. Therefore,_x000D_
adjusting protein supply and amino acid profiles can be considered as essential to achieve optimal performance and to control the_x000D_
intestinal pathogens with implication to bird and human health through contaminated poultry products. Moreover, reducing dietary_x000D_
crude protein leads to reduced nitrogen in the excreta with less potential for microbial conversion to ammonia. . We are specifically_x000D_
interested in determining optimal isoleucine requirements in low crude protein diets as this amino acid has been associated with_x000D_
poor performance (egg size) in these diets. Therefore, isoleucine, is a technical challenge where research data is lacking to_x000D_
