| 摘 要： | 旨在观察外源性cAMP对秦川犊牛生长性能及部分血液指标的影响。选取体质量相近的秦川犊牛公、母各6头(2月龄±10 d)。公母犊牛均分成试验组和对照组,进行120 d的饲养试验,试验组每隔10 d皮下注射cAMP标准注射液10 mL(0.6 mg/kg);对照组注射等量生理盐水。结果表明,和对照组相比,公犊牛末体质量、日增体质量分别提高8.99%、20.00%(P0.01),血清总胆固醇浓度在240 h内降低26.10%(P0.05),血糖浓度、生长激素质量浓度在72 h内分别提高6.50%、8.24%(P0.05),胰岛素质量浓度在48 h内提高7.43%(P0.05)。母犊牛末体质量、日增体质量分别提高7.94%、19.18%(P0.01),血清总胆固醇浓度在240 h内降低12.18%(P0.05),血糖浓度、生长激素质量浓度在72 h内分别提高8.30%、6.72%(P0.05),胰岛素质量浓度在48 h内提高6.15%(P0.05)。由此可知,注射外源性cAMP可显著提高犊牛的生长性能,并影响部分血液生化指标。

| Abstract: | In order to explore the effects of exogenous cAMP on the growth ability and blood parameters of Qinchuan calves,12 healthy Qinchuan calves(6 males and 6 females) at similar physical conditions were selected for a 120-d raising experiment.Calves were grouped randomly and equally into the experimental group and control group which had both genders(3 males and 3 females each group).Ten milliliters of 0.6 mg/kg exogenous cAMP(cyclic adenosine monophosphate) were injected subcutaneously into each subject of expe... |
