Abstract:The purpose of this study is to explore the effects of different levels of compound Chinese herbal medicine additives on the performance, blood biochemical indicators and carcass quality of white-feathered king pigeons, and to evaluate the effect and optimal dosage of self-made compound Chinese herbal medicine additives. In this study, 400 pairs of close-weight, healthy parent pigeons and 800 pigeons were randomly divided into 4 groups, with 4 repetitions in each group, and 25 pairs of breeding pigeons and 50 pigeons in each repetition. Each group added 0 (control group), 0.05%, 0.1%, and 0.15% compound Chinese herbal medicine additives to the basal diet respectively. The experimental period of this study was 28 days. The results showed that: ①Compared with the control group, the fertilization rate of pigeons in groups Ⅰ, Ⅱ, and Ⅲ was significantly increased by 0.88%, 1.82%, and 0.97% (P < 0.05), and the egg-laying interval of group Ⅱ was significantly reduced by 17.41% (P < 0.05) ②Compared with the control group, the body weight of pigeons in groups Ⅰ, Ⅱ, and Ⅲ increased significantly by 7.87%, 13.24%, and 6.58% (P< 0.05), and the average daily weight gain of pigeons in groups Ⅰ, Ⅱ, and Ⅲ increased significantly by 8.24%, 13.51%. %, 6.72% (P< 0.05). ③Compared with the control group, the serum TP level of pigeons in group II was significantly increased by 10.20% (P< 0.05), the serum level of GLO in group II was significantly increased by 7.49% (P<0.05), and the serum AST in group III was significantly increased by 22% (P<0.05), the serum LDL of pigeons in groups Ⅰ and Ⅱ significantly increased by 8.22% and 21.38% (P< 0.05).④Compared with the control group, the water loss rate of pigeon breast muscle in group Ⅱ was significantly reduced by 9.47% (P< 0.05), and the shear force of pigeon breast muscle in group Ⅱ was significantly reduced by 9.37% (P< 0.05). In conclusion, the compound Chinese herbal medicine additive can improve the production performance of the white-feathered king pigeon, improve the breast muscle quality and blood biochemical indicators of the pigeon, and the optimum addition ratio of the compound Chinese herbal medicine additive is 0.1%.
