Effect of phytase supplementation in maize–soybean based feed on comparative economy for broilers production

Abstract

A 42-days experiment with 150 one-day-old broiler chicks (Vencobb) was conducted in order to determine the effect of supplementation of phytase enzyme on comparative economics of rearing of broilers. Broilers were reared on phosphorus deficient maize-soybean based ration. A total of 150 chicks were grouped into five treatments (each treatment having two replicates) each containing 30 chicks and designated as C, T1, T2, T3 and T4. An experimental ration was formulated containing low available phosphorus (0.28%) than the normal requirement 0.45% as per BIS specifications (2007). Broiler starter and finisher ration contained 21.45 and 19.10 per cent crude protein, respectively. Energy and protein value of ration was kept equal for all treatments. Ration containing low available P was fed in control group while other treatments i.e. T1, T2, T3 and T4 were supplemented with phytase at the level of 250, 500, 750 and 1000 FTU/Kg feed, respectively. Based on comparative economics calculated in present investigation, it could be concluded that a dose of 500 FTU/Kg feed appear to be optimum level for better growth and to have profitable poultry farming by reducing feed cost.
