摘  要：
【目的】研究在日粮中使用10 kg饲用甜菜替代3 kg玉米青贮、在日粮中使用1/3开花期和现蕾期苜蓿干草对奶牛消化情况的影响。【方法】试验采用单因素设计。根据泌乳天数、胎次、年龄、产奶量相近的原则,选取荷斯坦奶牛51头,随机分为3组,分别饲喂对照组(甜菜粕+玉米青贮+1/3开花期苜蓿干草)、试验1组(饲用甜菜+玉米青贮+1/3开花期苜蓿干草)、试验2组(饲用甜菜+玉米青贮+现蕾期苜蓿干草)3种粗饲料组合的日粮,每组混合精料相同。试验预饲期7 d,正式期43 d。【结果】日粮中使用饲用甜菜和现蕾期苜蓿干草饲喂奶牛可以提高有机物、粗蛋白、粗脂肪和无氮浸出物的消化情况,但差异不显著(P>0.05)。【结论】现蕾期苜蓿干草的品质优于1/3开花期苜蓿干草,饲用甜菜是一种低纤维多汁饲料,日粮中使用饲用甜菜和现蕾期苜蓿干草可以提高奶牛的消化情况。

摘  要：
[Objective]The test focuses on the research on the effect of 10 kg fodder beet substituted for 3 kg corn silage,alfalfa hay of 1/3 the flowering period and from budding period in diets on digestion of dairy cows.[Method]One -Way ANOVA test design was used.The 51 cows with similar lactation day,parity, age,milk yield were divided into 3 groups randomly,the control group was fed coarse combinated fodder (sugar beet pulp + com silage + alfalfa hay of 1/3 the flowering period),Group 1 was fed coarse combinated fodder(fodder beet + com silage + alfalfa hay of 1/3 the flowering period),Group 2 was fed coarse combinated fodder(fodder beet + com silage + alfalfa hay of from budding period) respectively,and the mixed boars in each group of diets are the same.The experiment lasted for 50 days,including 7 days pre - experiment.[Result]The results showed that;Using fodder beet and alfalfa hay from budding period in the diet can improve digested condition of organic matter,crude protein,ether extract and nitrogen free extract. The differences were not significant(P > 0.05).[Conclusion]Nutritional quality of bud stage better than 1/ 3 bloom alfalfa hay,fodder beet is a kind of low fiber juicy feed.It can be concluded that using fodder and alfalfa hay from budding period in diets can improve digestion of dairy cows.
