Abstract


Abstract

Background: Low reproductive efficiency is the most critical problem faced by the livestock industry across the globe. Early embryonic loss is one the major cause of poor reproductive efficiency resulting in delayed pregnancy, fewer calves born, reduced milk production, slower genetic progress and substantial financial loss to the beef or dairy industry. The establishment of pregnancy results from the interaction between the embryo and the dam and is the culmination of a series of events initiated with development of the follicle and gametes. Among numerous internal and external factors nutrition has the potency to alter the micro-environment of the oocyte and the embryo, making it more hostile to optimal fertilization and pre-implantation embryonic growth. Understanding the impact of nutritional stress on oocyte function, embryo development and reciprocal signaling networks between the embryo and uterus will lead to alleviation of the problems of early embryonic mortality. 

Keywords:  Early embryonic loss, establishment of pregnancy, maternal recognition of pregnancy, interferon-tau, progesterone, nutritional stress, oocyte function, embryo development
