| 摘 要： | 试验在低和高水平纤维的基础饲粮中添加不同化合锌(1.基础对照;2.氧化锌;3.硫酸锌;4.氯化锌;5.硝酸锌;6.乙酸锌;7.葡萄糖酸锌),结果表明,1.高纤维使采食量(P<0.01),体增重(P<0.01)和饲料效率(P<0.05)显著提高;体增重在不同锌源之间比较有显著差异(P<0.05),低纤维时硫酸锌组最高,高纤维时乙酸锌组最高。2.高纤维使血清总蛋白和白蛋白含量降低(P<0.01),不同锌源对血清碱性磷酸酶活性有显著影响(P<0.01),但在低纤维时葡萄糖酸锌影响最大,在高纤维时硫酸锌影响最大(互作显著,P<0.05)。添加锌使血清球蛋白含量显著低于未加锌对照(P<0.05)。3.高纤维使加锌鸡肝脏、胰脏和胫骨中锌浓度明显降低(P<0.01)。加锌使组织中锌浓度显著提高,但在低纤维时,乙酸锌提高得最明显,在高纤维时硝酸锌(肝脏和胰脏)和氯化锌(腔骨)提高得最明显。

| Abstract: | Performance, blood biochemical parameters and zinc concentrations in the tissues were determined in chicks fed with low and high fiber basal diets supplemented with various zinc compounds (1. Control without supplementation of zinc; 2. Zinc oxide; 3. Zinc sulphate; 4. Zinc chloride; 5. Zinc nitrate; 6. Zinc acetate; 7. Zinc glucon-ate). The results showed that: 1. Feed intake (P<0.01), weight gain (P<0.0l) and feed efficiency (P<0.05) were significantly increased with high fiber diet. Zinc compounds had significant effect on weight gain (P<0.05). 2. High fiber decreased serum total protein and albumin contents (P<0.01). Serum alkaline phosphatase activity was higher in zinc-supplemented chicks than that in the control. Interaction between fiber level and zinc source was also significant (P<0.05). 3. Zinc concentrations in the tissues were significantly increased in zinc supplemented chicks, especially in zinc acetate-supplemented chicks when the diet contained low fiber and in zinc nitrate (liver and pancreas) and zinc chloride (tibia) -supplemented chicks when the diet contained high fiber. |
