Study of Early Pregnancy Diagnostic Proteins in Dairy Cows
Pregnancy failure caused by early embryonic death in dairy cows can result in significant economic losses to the dairy farm.Early and accurate pregnancy diagnosis in non-pregnant cows will improve the efficiency of pregnancy and shorten the number of days to nulliparity.This pa-per reviews recent domestic and international studies on pregnancy-associated proteins,body fluid proteins such as blood,urine,and milk of cows in early pregnancy stages,and proteomics to identify potential proteins in early non-pregnancy for accurate pregnancy diagnosis in early preg-nancy and to improve dairy production efficiency.
