Nutritional Evaluation of Potato Meal With and Without Enzyme Supplementation on Growth Performance, Nutrient Utilisation and Economics in Commercial Broilers.

Abstract

This study was conducted for nutritional evaluation of potato meal with and without enzyme supplementation in broilers. For the growth study, 240 chicks were distributed into 6 treatments having 40 birds per treatment (4 replicates x 10 chicks in each replicate). T₁ - Control diet, T₂-Control with cocktail ofenzyme @100g/q feed supplemented diet, T₃ - 25% crude protein of maize was replaced with potato meal without enzymes supplementation diet, T₄ - T₃+ cocktail   of enzymes @100g/q feed, T₅ - 50% crude protein of maize was replaced with potato meal without enzymes supplementation and T₆ - T₅ +cocktail of enzyme @100g/q feed. Control diets fed chicks had better final body weight, body weight gain and FCR as compared to 25% and 50% supplementation and  better digestibility parameters however dressing percentage reduced at higher level of supplementation whereas blood parameters remained within the permissible limit. Enzymes supplementation had a positive effect on the growth parameters and digestibility of nutrients irrespective of level but showed non-significant difference in carcass and blood profile of birds. It was concluded that from economic point of view potato meal can be incorporated during glut crude period up to 25% levels replacing protein content of maize.
