不同饲料添加剂对肉牛生长发育与产肉性能影响的研究

试验旨在研究两种添加剂在相同配方下对肉牛各组织器官生长发育的影响。选择健康的新疆周岁褐牛公牛30头,随机分为3组,试验组与对照组日粮相同,试验Ⅰ组精料中添加1%的肉牛育肥饲料复合添加剂,试验Ⅱ组精料中添加0.2%的巴尔吡尔。对肉牛骨骼与脏器组织生长发育、产肉性能进行测定与分析。结果表明,与对照组相比,试验Ⅰ、Ⅱ组在腰角宽、髋宽上差异显著(P<0.05),另外,能显著增加试验Ⅱ和试验Ⅰ组的血液与复胃的重量(P<0.05);具有增加胴体重与高档、优质肉产量,提高屠宰率,调控不同部位肌肉组织生长的效果。与对照组相比,试验Ⅰ、Ⅱ组在育肥增重、胴体、净肉、高档优质肉销售收益上获利增加额分别为42.7、130.6、142.22、141.6和-15.8、38.2、76.1、149.7元。因此,两种添加剂对动物的生长发育、肌肉、骨骼、脂肪组织具有一定的调控作用,巴尔吡尔添加剂具有增加肉牛脂肪代谢,降低体脂的功效,可作为安全、高效饲料添加剂应用于肉牛育肥生产中。

Preliminary Study of Different Additives on Beef Cattle Growth and Meat Performance

The aim of the experiment is to study two kinds of additives in the same formula,on the growth and development of beef cattle tissues and organs of influence.Thirty heads Xinjiang brown were randomly divided into three groups,patients with the control group has the same food.TestⅠboars group adding 1% compound additive of beef cattle fattening feed.Test Ⅱ boars group adding 0.2% powerfeel.The experiment for beef bones and organs organization of growth,production method and meat performance make analysis.The results showed that test Ⅰ group,the test Ⅱ group compared with the control,at the waist,hip wide wide angle,blood weight were significant difference(P<0.05).In addition,in the fattening increase heavy,trunks,puremeat,superior quality meat sales gains profit the revaluation were 42.7,130.6,142.22,141.6 and-15.8,38.2,76.1,149.7 yuan.Therefore,two kinds of additives on the growth and development of the animal,muscle,bone and adipose tissue had certain regulation function.Powerfeel had increased beef fat metabolism,reduced body fat effect.It could be used as a safe,efficient feed additives used in the production of beef cattle fattening.
