摘要
试验探究不同酶制剂及其组合对育成期水貂生长性能及免疫性能的影响。选取75日龄金州黑雄性水貂80只,随机分为4组,每组20个重复,每个重复1只。试验Ⅰ组为对照组,水貂饲喂基础日粮;试验Ⅱ组在基础日粮中添加200 g/t葡萄糖氧化酶,试验Ⅲ组在基础日粮中添加200 g/t过氧化氢酶;试验Ⅳ组在基础日粮中添加200 g/t葡萄糖氧化酶+200 g/t过氧化氢酶。试验期60 d。结果显示:与对照组相比,试验组育成期水貂的平均日增重均显著提高(P<0.05),试验Ⅳ组水貂的料重比显著降低(P<0.05)。与对照组相比,试验组育成期水貂腹泻率、死亡率显著降低(P<0.05)。水貂血清总超氧化物歧化酶(T-SOD)和谷胱甘肽过氧化物酶(GSH-Px)活性显著升高(P<0.05)。试验Ⅳ组水貂血清免疫球蛋白G (IgG)、白细胞介素-2 (IL-2)和干扰素-γ (IFN-γ)含量显著提高(P<0.05)。研究表明,酶制剂可以提高育成期水貂的生长性能、抗氧化能力和免疫性能,降低腹泻率和病死率,且葡萄糖氧化酶和过氧化氢酶的混合添加对育成期水貂生长发育的效果最好。
The experiment was to investigate the effect of different enzyme preparations and their combinations on growth performance and immune performance of growing minks. A total of eighty 75-day-old Jinzhou black male minks were randomly divided into four groups, with 20 replicates in each group and one mink in each replicate. Minks in experimental group Ⅰ(control group) were fed with a basal diet. The basal diet was supplemented with 200 g/t glucose oxidase in experimental group Ⅱ and 200 g/t catalase in experimental group Ⅲ. Experimental group Ⅳ was fed with a basal diet supplemented with 200 g/t glucose oxidase +200 g/t catalase. The experiment lasted for 60 d. The results showed that compared with control group, the average daily gain of minks in test group was significantly increased(P<0.05), the feed to gain ratio in test group Ⅳ was significantly decreased(P<0.05). Compared with control group, diarrhea rate and mortality rate of minks in test group were significantly decreased(P<0.05). The activities in serum of minks of T-SOD and GSH-Px were significantly increased(P<0.05). Serum IgG, IL-2 and IFN-γ content in test group Ⅳ were significantly increased(P<0.05). The experiment indicates that the enzyme preparation can greatly improve the growth performance, antioxidant capacity and immune performance of minks during growing period, and reduce the diarrhea rate and mortality rate. The mixed addition of glucose oxidase and catalase had the best effect on growth and development of minks during the growing period.
