• Abstract

  In cattle, needed increases in the reproductive efficiency depend on a greater understanding of the endocrine, cellular and molecular mechanisms that result in higher conception rates. The central thesis of this project is that there is a "molecular signature" associated with optimal conditions of maternal receptivity to the embryo. Such signature is defined by a hallmark profile of abund…

• Abstract

  Supplementing with progesterone (P4) at the beginning of diestrus increases pregnancy rates, but also anticipates the functional and structural regression of the corpus luteum (CL) which may impair the success of the strategy. We speculate that this anticipation (early luteolysis) can be prevented by the presence of the conceptus (embryo + attached membranes), which is the main agent resp…

  Effect of embryo on the early luteolitic process in beef cows supplemented with P4, BP.DR

• Abstract

  During bovine pregnancy, preimplantation period is critical, since the development of conceptus is fully dependent on the intrauterine environment. Proteins, carbohydrates, lipids, growth factors and ions, which are synthesized and secreted by endometrial glands and that compose the histotrophic, have influence in maintaining conceptus until the time of implantation. It indicates that ute…

• Abstract

  Long-acting injectable progesterone (P4) supplementation at the onset of diestrous increases the conception rate of beef cows. However, the anticipation of functional and structural regression of the corpus luteum (CL; i.e. anticipated luteolysis) has been observed, resulting in subsequent pregnancy loss in 30-50% of animals subjected to this treatment, reducing the efficacy of P4-supplem…

• Abstract

  The embryotrophic effects of supplementary progesterone (P4) are associated with changes in endometrial function that causes changes in the uterine luminal fluid (ULF). However, nature of components ULF associated with conceptus growth are largely unknown. Thus, this study aims to: (1) characterize the composition of the ULF (amino acids, proteins, carbohydrates and other) recovered on Da…

• Abstract

  There is increasing need of nonhuman primates (NHPs) for biomedical research, which generates the need of efficient methods to ensure adequate supply. The use of ARTs have overcome many of the problems encountered. The rhesus monkey (Macaca mulatta) is one of the most commonly used NHP in research. Although, there have been many advances in the application of ARTs in this species, cryopre…

• Abstract

  Development and implementation of genetic selection of dairy cattle has been the major method to improve productivity per animal; however, selection has been focused on production traits and only more recently reproduction and health traits. Moreover genetic selection for fertility traits has been slow because of use of indirect methods that are influenced more by the environment than con…
