The Enzymes That Affect the Reproduction in Certain Farm Animals

Abstract

The study was carried out to determine the enzymes that affect the reproduction in certain farm animals. Studies of cattle, sheep, chicken and fish as animal species were examined. Researches of holstein, simmental and montofon from different cattle breeds, in addition, as fish specie sea bream (Sparus aurata L.) were mentioned. The levels of Glutathione S-transferase and uterine arginase in cattle, sorbitol dehydrogenase and aldose reductase in sheep, Glutathione peroxidase in chicken and aromatase in sea bream effect on reproduction and reproductive performance were researched.
