Abstract

The importance of the buffalo species is linked to its production abilities (meat, milk, leather, horn and etc.) and its traction force, leading to notoriety in the world economic scenario and investments in technological programs similar to those applied to cattle. Thus, the search for better reproductive indexes is leading to the selection of genetically superior animals by application of reproductive biotechniques, one of the main being artificial insemination and embryo transfer. In buffaloes, many factors affect reproductive performance, one of which is the long breeding interval in the species, as well as failures in the detection of estrus due to absence of estrus signs. Early diagnosis of gestation is an important tool to increase reproductive rates in cattle and buffalo, since it allows shorter intervals between calving due to the detection of non-pregnant animals or possible early embryonic losses, allowing the resynchronization of estrus and use in artificial insemination and embryo transfer programs. Due to the approach on the early diagnosis of gestation, numerous studies have been developed with the purpose of finding markers that can predict gestation early, in order to advance a new resynchronization of estrus, reducing the interval between deliveries and guaranteeing increased productivity . The objective of this study is the identification of serum, urinary, uterine and embryonic fluid markers and their correlation to the early diagnosis of gestation, as well as the identification and characterization of the follicular fluid protein profile and buffalo oocytes.
