ABSTRACT
The effect of post pelleting liquid phytase supplementation was evaluated in broilers on the basis of growth production, plasma and tibia phosphorus. The (n=504) day-old broiler chickens procured randomly allocated into 6 treatments dietary treatments were: B positive control (PC) diet (0.42% available phosphorus in grower feed, A negative control (NC) diet with (0.30% avail. P in starter and 0.26% avail. phosphorus in grower) while four diets C, D supplemented with NC+ (500 and 750 powder phytase units (FTU)/kg) and G, H supplemented with NC+ (500 and 750 liquid phytase units (FTU)/kg) respectively. Pelleting temperature was set at 85°C during feed processing production. Blood, ileal digesta, weight of visceral organs, left tibia were sampled for the quantity of phosphorus in plasma, its digestibility and tibial calcium and phosphorus. The present study reported that H group was found higher in FI, BWG and FCR as compared to other groups. Higher gizzard, liver and heart weight were recorded in group A and B while tibia ash, Ca and P in group H. Described results concluded that supplementing liquid phytase enhances breakdown of phytate phosphorus, phosphorus availability, digestibility, and growth performance.
