Abstract

The Pleuroteus mushroom has immense growth and health promoting potentials. However, reports on its utilization in the diet of the rabbit is sparse. Therefore, a 56-day feeding trial was conducted to investigate the effects of dietary inclusion of Pleurotus tuber-regium sclerotium powder (PTRSP) in growing rabbits. Forty–eight crossbred rabbits aged between 7 and 9 weeks with average initial weight of 700±25 g were used for the study. The rabbits were allotted to 4 experimental diets containing 0.0, 25.0, 50.0 and 75.0 g/kg PTRSP, respectively. Each treatment had 4 replicates with three rabbits each in a completely randomised design. Growth performance, serum biochemistry and intestinal morphology were determined. The weight gain and feed conversion ratio were better (P<0.05) in rabbits fed diet containing 50.0g/kg PTRSP. Rabbits fed diet containing 75.0 g/kg PTRSP had lower (P<0.05) serum cholesterol, creatinine and alanine transaminase and higher (P<0.05) total glucose concentration compared to those receiving other experimental diets. Rabbits fed diet with 50.0g/kg PTRSP had higher (P<0.05) caecal apical width than those fed diet containing 0.0 g/kg. Inclusion of 50.0 g/kg of PTRSP in the diets of rabbits is beneficial for improved growth, cholesterol metabolism and intestinal morphology without any adverse effects.
