摘要
为研究富维生素C中药负离子复合制剂对断奶仔猪生长性能的影响,从仔猪增重、生长激素、表观消化率、腹泻率及死亡率和肠道菌群等方面进行了相关研究。试验随机选取60头健康无病、日龄相近,血缘关系一致,体重为(8±0.77)kg的杜×长×大三元杂交断奶仔猪,按公母各半随机分为对照组和试验组,每组30头,设3个重复,每个重复10头。对照组饲喂基础日粮,试验组饲喂基础日粮+0.5%富维生素C中药负离子复合制剂,试验期49d,预饲期7d。结果表明:试验组的日增重差异极显著(P<0.01);饲料养分表观消化率、生长激素GH、皮质醇COR均差异显著(P<0.05);断奶仔猪腹泻率显著降低(P<0.05),具有促进乳酸菌增殖,抑制大肠杆菌繁殖的作用。此项研究为无抗饲料添加剂在断奶仔猪生产中的推广应用提供了可靠依据。
In order to study the effect of vitamin C rich traditional Chinese medicine anion compound preparation on growth performance in weaned piglets, weight gain, growth hormone, apparent digestibility, diarrhea rate, mortality, and intestinal flora of piglets were studied. In this study, 60 healthy, disease-free, closely related, 8+0.77 kg weight Duroc × Landrace × Large ternary hybrid weaning piglets at similar age were randomly selected, and divided into 2 groups with 3 replicates in each group, and 10 piglets in each replicate. The control group was fed basic diet, and the experimental group was fed basic diet+0.5% vitamin C-rich Chinese medicine anion compound preparation. The trial period was 49 days an the pre-feeding period was 7 days. The results showed that the daily weight gain of the experimental group was extremely significant difference ( P <0.01);apparent digestibility, GH and COR were significant difference ( P <0.05);diarrhea rate of weaned piglets significantly decreased ( P <0.05), the growth of Lactic acid bacteria was effectively promoted and the growth of Escherichia coli was inhibited. This study provides a reliable basis for the promotion and application of non-resistant feed additives in weaning piglets.
