Abstract: Infertility is regarded as one of the major reasons for reduced life-time milk production in dairy animals. The causes of infertility in dairy animals are many and are complex, among which post-partum uterine infection alone accounts to around 25-30 per cent. A healthy uterine environment is supposed to be the main determinant for good fertility as any sort of damage to endometrium can disturb the normal reproductive functions leading to infertility. The development of uterine infection is determined by the immune status and execution of the same against the infectious agent, number/load of bacteria and its virulence. Uterine infection may prolong the time of uterine involution, resumption of first postpartum estrus, increases the number of services per conception, number of days open and incurs a huge economic drainage to the dairy industry. From the current literature it is quite evident that the uterine infections not only affect the milk production but also have negative impact on the ovarian follicular development and steroid production, expression of estrus and ultimately the conception thereby prolonging the intercalving interval. Keeping in view all the above facts, the following review provides a better understanding of uterine infections and developing effective preventive measures for minimizing the incidence of uterine infections in dairy animals.
