The Effects of Yucca Schidigera Extract and Multi-carbohydrase in Different Crude Protein Diets on Growth Performance, Nutrient Digestibility, Carcass Parameters and Excreta Noxious Gas Contents in Broilers

The scarcity and increase in the price of animal feeds have attracted attention nutritionists to address this issue. inclusion plant extracts enzymes protein-reduced diet could be a feasible strategy reducing feed cost. Therefore, purpose study was assess impacts Yucca schidigera extract multi-carbohydrase low crude protein (CP) diets broiler on growth performance, nutrient digestibility, carcass metrics, noxious gas levels excreta. A total 480, 1-d-old ROSS 308 were randomly allocated into 4 dietary treatments, six replication, 20 birds/cage. Phase 1, T1(CP 21%, ME 2,969 kcal/kg); T2 (CP 19%, 2,863 kcal/kg + 0.02% Yucca); T3 17%, 2,865 T4 2,861 0.1% multi-carbohydrase). 2, T1 3,086 2,977 15%, 2,978 Although addition YS CP performance did not improve, it revealed positive result parameters, emission. Overall, broilers supplemented with (0.1%) demonstrated best production performances compared other treatment groups. Thus, combination added boost performance.
