• Abstract

  Oocyte maturation is regulated by several mechanisms that act together in the cumulus-oocyte complex (CCO) included in the ovarian follicle. However, the in vitro culture of oocytes causes an imbalance of regulatory agents, resulting in lower efficiency and quality of the oocytes. Methods that temporarily block meiotic maturation in vitro may mimic some of the follicular signals that occu…

• Abstract

  Feed efficiency is very important for breeding programs. The residual feed intake (RFI) is an indicator that has a correction of dietary intake for animal weight and weight gain. In addition, puberty is important for the improvement of breeding cattle. The production and semen quality are influenced by several factors, especially nutrition. Polyunsaturated fatty acids (PUFA) have effects …

• Abstract

  Once bovine in vitro produced (IVP) embryos are more susceptible to oxidative damage, the supplementation with antioxidants to in vitro maturation media has shown satisfactory results on embryonic development. Besides the use of antioxidants, the addition of lipogenesis inhibitors and/or lipolysis stimulators also reflects positively on the development, quality and embryonic cryotolerance…

• Abstract

  Since bovine embryos in vitro produced are more susceptible to oxidative damage, antioxidant supplementation has been shown effective to improve embryo quality. In addition, other factors have been shown to play an important role in embryonic development in adverse conditions, such as growth factors. To improve the quality, development potential and the success of cryopreservation of bovi…

• Abstract

  Aiming to reduce the impact of heat stress on the oocyte quality, this study will be conducted with the overall goal to evaluate the effectiveness of melatonin supplementation on bovine oocytes exposed to high temperatures on in vitro maturation. For this purpose, cumulus-oocytes complexes (COCs) will be assigned in a 2 x 6 factorial arrangement experiment with two maturation temperatures…
