Biochemical investigation of blood plasma during estrus and diestrus in repeat breeder cows

Abstract

Repeat breeder syndrome is considered as one of the most important causes of infertility in dairy cattle. Deficiencies of various blood biochemical constituents are the major causes for repeat breeder syndrome (Dutta et al., 1991). This study was carried out to examine some plasma biochemical constituents on day 0 (estrus) and 10 (diestrus) of the estrous cycle in repeat breeder cows.
