新型预混料对奶牛酒精阳性乳防治作用的研究
Effect of the New Premix on Prevention and Treatment of Alcohol Positive Milk in Dairy Cow
摘要
Abstract
Two experiments were designed to verify the effect of new premix on prevention and treatment of alcohol positive milk(APM)in dairy cow.In the experiment 1,according to lactation days and the occurrence degree of APM,100 late lactation Holstein cows were divided into four groups in the completely randomized block method.Treatments were:Control group,low dose group(LDG),medium dose group(MDG),and high dose group(HDG)with 0,50,100 and 150 g new premix per cow per day,respectively.Each group included 5 replicates with 5 cows in every replicate.The test period was 26 days and 3 days was one sampling period.In the experiment 2, according to the grouping method of experiment 1,370 late lactation Holstein cows were divided into control group(n=185)and the test group(n=185)with 0 and 100 g new premix per cow per day,respectively.The test period was 35 days and 5 days was one sampling period.Milk sam-ples were mixed with an equal amount of 75% neutral alcohol to detect agglutination reactions.The results of experiment 1 showed that cows fed 50 g new premix had a few effect to decrease the incidence of APM(P>0.05)compared with control group.However,cows fed 100 and 150 g new premix could significantly decrease the incidence of APM(P<0.05),especially the incidence of strong APM(P<0.01).There was no significant difference for incidence of APM between the cows fed 100 and 150 g new premix(P>0.05).The results of experiment 2 showed that the rate of the total APM and strong APM were decreased by 75.73% and 90.82% in cows fed 100 g new premix by the end of the experiment,respectively.In conclusion,the new premix could prevent and treat the APM effectively,and the effective addition of the new premix in the diet should be 100 g per cow per day.关键词
