Abstract

The ideal protein (IP) concept proposes setting the ratio of digestible essential amino acid (AA) to lysine in the diet as in their requirements, thus allowing for reduced crude protein (CP) rations. However, since sub-clinical challenges may reduce AA digestibility and/or increase AA demand for immune responses (Adedokun, Helmbrecht, & Applegate, 2016), the IP concept might be affected. We hypothesised that supplementation of threonine (Thr), arginine (Arg), and glutamine (Gln) to IP based reduced CP diets could improve broiler resilience to a combined reused litter and sub-clinical coccidiosis challenge.
