Abstract
[Objective]The aim of this study was to investigate the effects of rumen passing glucose on milk yield and milk indexes of Holstein dairy cows in early lactation.[Method]28 healthy Holstein cows with postpartum weight greater than 7 DIM and less than 70 DIM were selected and paired according to the principle of similar weight,parity,body condition score,lactation age,and milk production.They were randomly divided into two groups(experimental group and control group),with 14 cows in each group(7 cows with postpartum weight ranging from 7 to 35 DIM and 7 cows with postpartum weight ranging from 35 to 70 DIM).The experiment started at the current lactation age of the experimental cattle and ended at 35 or 70 days.The control group of cows were fed with a conventional feed from the cattle farm,while the experimental group of cows were fed with a"conventional feed+200 g/head·d Aniyou-G".The conventional diet is the TMR diet for existing lactating cows in the pasture.The individual milk production of experimental cows is measured every 7 days.Milk composition analysis(DHI data):milk samples were collected at the beginning of the test and on the 30th day of the test,and milk protein,milk fat,lactose,non fat milk solids,blood urea nitrogen and somatic cells were measured by the milk composition analyzer.[Result](1)adding 200 g/head·d Aniyou-G to the diet of Holstein cows during early lactation can significantly increase milk production,and can significantly increase the content of milk fat,milk protein and non fat solids,and reduce the content of milk blood urea nitrogen and somatic cells.关键词
