Selection of dairy cattle for higher milk yield, without considering important nonproductiontraits, has decreased reproductive efficiency. Thus, low reproductiveperformance is a major problem in high yielding dairy cattle. Previous studies showedthat dietary manipulation to improve fertility holds much promise and dietary fats havepositive effects on reproductive functions in high yielding dairy cattle. Positive effects offats on reproductive performance due to the fatty acids, which are the precursors ofprogesterone and prostaglandins. Progesterone and prostaglandins hormones are mostimportant factors that play a role on the control of reproductive functions. The amount oflinoleic, linolenic and arachidonic fattty acids in ration can be increase or decreaseprogesterone and prostaglandins synthesis especially PGF2α from ovary and uterus,respectively. Also fatty acids can be influence follicular development, ovulation,embryonic implantation and maternal recognition of pregnancy. This review focuses onthe relationships between dietary fatty acids and reproductive functions such as hormoneprofiles, ovarian function and follicular development, oocyte quality, embryodevelopment, embryonic implantation and maternal recognition of pregnancy in dairycattle
