北苍术秸秆颗粒饲料对肉牛血液生理生化指标及增重效果的影响
The Effect of Atractylodes macrocephala Straw Pellet Feed on Blood Physiological and Biochemical Indicators and Weight Gain of Beef Cattle
摘要
Abstract
Forty second-generation crossbred bulls of Simmental and Chengde local yellow cattle,weighing around 500 kg and around one year old,were randomly divided into a control group(Group A),a B group,a C group,and a D group.They were fed with Atractylodes macrocephala pellet feed instead of 0,5%,10%,and 15%of corn stover in their diet,respectively.A 120 day feeding experiment was conducted,and the weight of the cattle was measured and blood physiological and biochemical indicators were measured by neck vein blood sampling every month.The effects of Atractylodes macrocephala pellet feed on beef cattle fattening and physiological and biochemical indicators were analyzed;The research results show that Atractylodes macrocephala pellet feed can increase the total cholesterol and calcium levels in the blood of beef cattle.Long term feeding has no adverse effects on the immune function and blood physiological and biochemical indicators of beef cattle,and can increase the daily weight gain of beef cattle by 3.73%to 10.45%;The feeding experiment showed that using 10%Atractylodes macrocephala straw pellet feed instead of corn straw to feed beef cattle had the best fattening effect and could be used as coarse feed for beef cattle.关键词
