不同β-受体激动剂添加模式对肉牛血液生化指标和激素水平的影响
Different Feeding Mode of β-agonists Treatments on Plasma Biochemical Parameters and Internal Hormone Levels in Cattle
摘要
Abstract
The experiment was aimed to study different feeding mode of β-agonists treatments on plasma parameters and internal hormone levels in cattle.15 healthy Simontal cattle with similar body weight (257.9 kg±33.3 kg) were randomly divided into three groups.The cattle were fed with the same basal diet,and the test group Ⅰ were daily treated with 670.0μg/(kg · BW) ractopamine while the test group Ⅱ were daily treated with a mixture of ractopamine,salbutamol and clenbuterol (223.3,50.0 and 5.3 μg/(kg · BW),respectively) for 28 consecutive days,and the period of withdrawal was 28 days.The results showed that at the 28th day of the treatment,plasma free fatty acid (FFA) concentrations in test groups Ⅰ were significantly lower than that in control group (P＜0.05),plasma glucose (GLU) and FFA concentrations in test groups Ⅱ were significantly lower than that in control group (P＜0.05);The levels of hormone in plasma were not significantly affected by β-agonists during the whole test period (P＞0.05) except that the INS level in test groups Ⅰ was significantly lower than that in control group (P＜0.05) at the 28th day of the withdrawal.These results demonstrated that plasma FFA in cattle could be used as potential biomarkers to supervise the illegal use of β-agonists.关键词
