SUBSTITUTION OF LYSINE WITH MUSHROOM (Pleurotus cystidiosus) IN BROILER CHICK'S DIET

ABSTRACT: Effect of inclusion of mushroom (Pleurotus cystidiosus) to substitute lysine in the diet of broiler chicks was investigated. The study lasted for a period of twelve weeks. Twenty four broiler chicks were subjected to two different dietary treatments (Diet I contained 0.22% of mushroom while Diet II contained 0.22% of synthetic Lysine and was used as control). The different treatments had four replicates of three birds each housed in a metabolic cage. Two parameters, mean weight gain and mean feed intake were recorded. Student t- test showed that there was no significant difference (P>0.05) in the mean weight gain for the chicks on the two treatments (DI-3550g and DII-3375g) and mean feed intake for the chicks on the two treatments (DI-502.5g and DII-420g). Consequently, the observed results showed that mushroom can be used to substitute lysine in the diet of broiler chicks.
