Effect Of Different Levels Of Vitamin E In Diet On Perinatal Cows

This paper studies the diet with different among the level of cows healthy, vitamin E and reproductive performance of production performance, aims to further research about perinatal cows physiological characteristics, and explores the dairy diet among appropriate vitamin E, and additives for further research of metabolic barrier cow perinatal disease prevention and treatment of mechanism and provide theoretical guidance.This experiment selection perinatal China holstein cows rank 32 head randomly divided into 4 groups, according to the requirements of vitamin E NRC for standard, design for 1 times NRC NRC 1.5 times, twice, NRC vitamin E additives, along with control group of vitamin E for adding 0IU/d?head(â… ), 800IU/d?head(â…¡), 1200IU/d?head(â…¢), and 1600IU/d?head(â…£). According to the research on the group after the fed cows in blood routine examination, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), production and milk in each component and somatic number (SCC) type, clinical mastitis incidence, each time, calves born from heavy, and select the diets perinatal suitable amount of vitamin E.Test results show that adding vitamin E, grain production and cows healthy for perinatal aspects of performance, reproductive performance has positive function of each index data and process analysis, theâ…¡,â…¢, various testing indexâ…£housed on the wholeâ… than in control group were extremely significant group,â…¡group andâ…¢,â…£group, on the whole, that there were significant differences 800IU/d?head of vitamin E additives and cannot be completely meet the physiological needs, perinatal cows,â…¢group compared withâ…£between groups, on the whole, but the difference was not significant differences exist, and some items that can be obtained with the data of the increase of adding amount of vitamin E, the indexes have advantages to the cow change trend. But since vitamin E cost more, considering the actual situation and dairy produce economic benefits, so choose 1200IU/d?head for the proper recommendation quantity.
