- Abstract
The scarcity of feed raw materials with a consequential increase in the price of animal feed has attracted the attention of nutritionists to find a viable option to address this issue. The inclusion of plant extract and enzyme to the energy- and protein-reduced diet could be a viable strategy that would contribute to reducing the feed cost. Therefore, the purpose of this study was to determine how different crude protein diets with Yucca schidigera extract and multicarbohydrase could impact broiler growth performance, nutrient digestibility, carcass metrics, and noxious gas concentrations in the excreta. A total of 480 oneday (d)-old broilers (ROSS 308), with initial body weight (BW) of 45.2 ± 0.3 g were randomly assigned into four (4) dietary treatments, each with six replication cages and 20 birds per cage. In phase I (starter), broiler were fed with diets containing T1 (CP 21%, ME 2,969 Mcal/kg); T2 (CP 19%, ME 2,863 Mcal/kg + 0.02% Yucca); T3 (CP 17%, ME 2,865 Mcal/kg + 0.02% Yucca); and T4 (CP 17%, ME 2,861 Mcal/kg + 0.02% Yucca + 0.1% a-1, 6-galactosidase and ß-1,4-mannanase). During phase II (grower) diets contained T1 (CP 19%, ME 3,086 Mcal/kg); T2 (CP 17%, ME 2,977 Mcal/kg + 0.02% Yucca); T3 (CP 15%, ME 2,978 Mcal/kg + 0.02% Yucca); and T4 (CP 15%, ME 2,978 Mcal/kg + 0.02% Yucca + 0.1% a-1,6-galactosidase and ß-1,4-mannanase multi-carbohydrase). The addition of Yucca extract and multi-carbohydrase to the low CP diets revealed a positive result on the growth performance, nutrient digestibility, carcass parameters, and noxious gas emission. Overall, broilers supplemented with Yucca schidigera extract 0.02% and a-1,6-galactosidase and ß-1,4-mannanase multicarbohydrase (0.1%) demonstrated the best production performances compared with the other treatment groups. Thus, a combination of Yucca schidigera and multi-carbohydrase could to be added to the diets with low CP to boost broiler production performance.
