Abstract
Abstract A trial was conducted to determine the coefficient of ileal apparent digestibility (CIAD) and ileal true digestibility (CITD) of amino acids of raw pea protein concentrate (PPC), soya protein concentrate (SPC), soya bean meal (SBM) and fullfat soya bean (FFSB) in 21-day-old broilers. Four diets were formulated based on maize starch and sucrose and with the test ingredient as the unique source of dietary protein (200 g/kg). In addition, a nitrogen free diet was formulated to estimate the basal ileal endogenous losses of amino acids. Chicks were fed a commercial maize-SBM diet from 1 to 17 days and then, their respective experimental diets from 18 to 21 days of age. All feeds were offered ad libitum in mash form and each treatment was replicated 6 times. Chicks fed SPC and SBM had higher CIAD of arginine, methionine and valine than chicks fed PPC (P
