Abstract:
The purpose of this study was to examine the impact of phyto-protease produced from ginger on blood biochemical indicators, gastrointestinal health, litter quality, and nutrient retention. A total of 250-day-old broiler chicks (ROSS 308) were obtained from a hatchery, with similar weight, age, breed, and sex. These chicks were divided into five treatment groups: T1, T2, T3, T4, and T5. Each group consisted of five replicates (10 chicks per replicate). T1 served as the control group, while T2 and T3 had diets with 4% and 6% animal protein concentrate (APC), respectively. T4 had the same diet as T2 but included ginger-derived protease (GPZ) at 0.02%, and T5 had the same diet as T3 with GPZ at 0.02%. During the starter phase (days 1-21), the supplementation of phyto-protease improved body weight gain (BWG) and feed conversion ratio (FCR). The inclusion of APC in the broiler diet adversely affected BWG and FCR. However, the addition of phyto-protease enzyme to diets containing 4%and 6% APC resulted in better BWG and FCR. In the finisher phase, supplementation with phyto-protease continued to improve BWG and FCR. The inclusion of phyto-protease resulted in a significant (p<0.05) improvement in the weight of lymphoid organs and carcass yield. Salmonella and Escherichia coli(E. coli) counts were lowest in groups supplemented with phyto-protease and highest in groups fed APC. Conversely, Lactobacillus counts increased with the supplementation of phyto-protease compared to other groups. Supplementation with phyto-protease significantly affected nutrient digestibility (ND) and apparent metaboliz able energy (AME) in broilers fed with APC. The digestibility of dry matter (DM), crude protein (CP), and ether extract (EE) was lower in the group fed with APC alone. Phyto-protease supplementation significantly increased ND and AME. Dietary supplementation with ginger derived phyto-protease enzyme could be a viable approach to enhance production performance and nutrient digestibility in broiler diets that use higher levels of animal protein sources with deficient protein and amino acid levels.
