摘要
通过皮下注射和饲料添加不同剂量dbcAMP制剂进行饲养试验,研究其对猪生长和胴体组成的调控效果。结果表明:皮下注射1.0mg/kg和饲料添加20mg/kg为最佳调控剂量,在生长猪阶段,日增重分别提高13.61%和15.41%(P<0.05);料重比分别降低18.81%和19.10%(P<0.05);在肥育猪阶段日增重和料重比差异不显著(P>0.05)。dbcAMP可提高猪血液T3、GH、IGF-I和cAMP的浓度(P<0.05),使血脂、TG、HDL和VLDL含量以及TP、ALB和GLOB含量增加(P<0.05),脂肪酶、ALT、AST和ALP活性提高(P<0.05)。证明dbcAMP制剂明显提高猪的生长性能,改善胴体组成。
This experiment was done to evaluate the effects of dbcAMP on the growth and carcass composition in pig by subcutaneous injection and basic diets supplementation with different dosages. The results showed that 1.0 mg/kg by subcutaneous injection and 20 mg/kg by basic diets supplementation was the most suitable dosage. In the growing period, daily gain was increased by 13.61%and 15.41%(P<0.05),feed/gain was decreased by 18.81%and 19.10%(P<0.05)differently. In finishing period, daily gain and feed/gain were not influenced.and contents of T3, GH, IGF-I, cAMP, TG, HDL, VLDL, TP, ALB and GLOB in blood was increased(P<0.05)and activity of lipase, ALT, AST and ALP in serum was improved remarkably(P<0.05)by using dbcAMP. The results indicate that dbcAMP can promote pig growth and improve its carcass composition.
