| Sumario: | Reproduction is the basis of bovine meat and milk production: As a direct result of reproduction, the cycles of calf and milk production are renewed. However, there are many limiting steps in this process as: low pregnancy rates and long open days that result in increasing parturition intervals. Reproductive efficiency in dairy and beef cattle is multifactorial. Nutrition is one of the most important factors affecting this efficiency, and some results have shown that feeding diverse sources of lipids and specifically, fatty acids (FA) can result in a better reproductive efficiency. As a nutrition strategy to improve reproductive efficiency, FA of the omega 3 (n-3) and omega 6 (n-6) families have been studied, and it has been shown that these FA can control follicular development, production of progesterone in the corpus luteum, and secretion of PGF2α from the endometrium, increasing embryonic survival and pregnancy rates. The purpose of this revision is to analyze the possible mechanisms by which FA in the diet improve reproductive efficiency of cows, with especial emphasis on FA n-3 and n-6. |
