Profitability and sustainability are very important considerations for our poultry customers. The poultry sector in Canada is inx000D
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 arex000D
looking for solutions to minimize use of AGP and to decrease environmental impact particularly ammonia gas emissions in poultryx000D
houses which have detrimental effects on birds and humans. Dietary crude protein concentration has a significant impact on thex000D
intestinal microbiota, both qualitatively and quantitatively. For example, several studies indicate that high protein diets with excessx000D
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 thex000D
intestinal pathogens with implication to bird and human health through contaminated poultry products. Moreover, reducing dietaryx000D
crude protein leads to reduced nitrogen in the excreta with less potential for microbial conversion to ammonia. . We are specificallyx000D
interested in determining optimal isoleucine requirements in low crude protein diets as this amino acid has been associated withx000D
poor performance (egg size) in these diets. Therefore, isoleucine, is a technical challenge where research data is lacking tox000D
support formulation decisions.x000D
