【摘要】：研究以乌梅为主的复方中草药对罗斯肉仔鸡生长性能、肌肉品质、免疫功能和肠道菌群的影响。将300只肉仔鸡随机分为5组,分别为空白对照组、金霉素对照组(50 mg/kg)、复方中草药低剂量组(5 m L/L)、复方中草药中剂量组(10 m L/L)、复方中草药高剂量组(20 m L/L),掺入饮水喂饲42 d。结果表明,与空白对照组相比,复方中草药各剂量组显著提高肉鸡全期日增重(p0.05),高剂量效果最明显;中、高剂量组的胸肉弹性显著提高(p0.05),高剂量组的胸肉咀嚼性和亮度显著提高(p0.05);高剂量组的胸腺指数显著提高(p0.05),中、高剂量组的法氏囊指数显著升高(p0.05);高剂量组的肠道内乳酸菌菌落数显著提高(p0.05)。结果表明,本研究设置的复方中草药剂量(5、10、20 m L/L)范围能不同程度改善肉仔鸡生长过程,其中以20 m L/L添加量促进效果最显著。
[Abstract]:The effects of compound Chinese herbal medicine mainly on the growth performance, muscle quality, immune function and intestinal flora of Roth broilers were studied. 300 broilers were randomly divided into 5 groups: blank control group, chlortetracycline control group (50 mg 路kg ~ (-1), low dose Chinese herbal medicine group (5 mL / L), compound Chinese herbal medicine medium dose group (10 mL / L), compound Chinese herbal medicine high dose group (20 mL L / L) and drinking water fed for 42 days. The results showed that, compared with the blank control group, each dose group of compound Chinese herbal medicine significantly increased the daily gain of broilers during the whole period, and the effect of high dose was the most obvious. The elasticity of breast meat in the high dose group was significantly increased, the mastication and brightness of the breast meat in the high dose group were significantly increased, and the thymus index in the high dose group was significantly higher than that in the high dose group, and the thymus index in the high dose group was significantly higher than that in the control group. The bursa index in the high dose group was significantly higher than that in the control group (P 0.05), and the number of lactic acid bacteria in the intestinal tract in the high dose group was significantly higher than that in the control group (P 0.05). The results showed that the range of compound Chinese herbal medicine in this study could improve the growth process of broilers in varying degrees, and the dosage of 20 mL / L was the most effective.
