Resveratrol, a potent antioxidant, can be an alternative semen extender constituent to protect spermatozoa against reactive oxygen species (ROS); however, effects on sperm quality postthawing and sperm function is not well understood. This study, therefore, was conducted to investigate effects of resveratrol supplementation to semen extender on sperm quality postthawing. Bull semen was cryopreserved using extenders not supplemented or supplemented with 0.05, 0.1, or 1 mM resveratrol. Supplementation of extender with resveratrol at 0.05 mM resulted in greater (P < 0.05) sperm progressive motility, average path velocity, straight linear velocity, linearity and straightness when compared with no or 1 mM supplementations. Furthermore, effects of 0.05 mM resveratrol supplementations on plasma membrane and acrosome integrity and sperm fertilization capacity using in vitro procedures were investigated. Supplementation of semen extender with resveratrol resulted in a greater (P < 0.05) proportion of frozen-thawed spermatozoa with an intact acrosome and plasma membrane. Results from in vitro fertilization studies indicated there were no differences (P> 0.05) when there was no supplementation or supplementation with 0.05 mM resveratrol on embryo development to the cleavage and blastocyst stages. In conclusion, addition of resveratrol to bull semen extender resulted in greater sperm quality post-thawing in a dose-dependent manner, with values for variables related to sperm quality being greater when there was resveratrol supplementation at the 0.05 mM concentration. Proportion of embryo developing to the cleavage and blastocyst stages after in vitro fertilization was not affected by resveratrol supplementation to semen extenders.

The timing of puberty and subsequent fertility in female mammals are dependent on the inte-gration of metabolic signals by the hypothalamus. Pro-opiomelanocortin (POMC) neurones inthe arcuate nucleus (ARC) comprise a critical metabolic-sensing pathway controlling the reproductive neuroendocrine axis. a-Melanocyte-stimulating hormone (aMSH), a product of thePOMC gene, has excitatory effects on gonadotrophin-releasing hormone (GnRH) neurones andfibres containing aMSH project to GnRH and kisspeptin neurones. Because kisspeptin is a potentstimulator of GnRH release, aMSH may also stimulate GnRH secretion indirectly via kisspeptinneurones. In the present work, we report studies conducted in young female cattle (heifers) aiming to determine whether increased nutrient intake during the juvenile period (4-8 months ofage), a strategy previously shown to advance puberty, alters POMC and KISS1 mRNA expression, as well as aMSH close contacts on GnRH and kisspeptin neurones. In Experiment 1, POMCmRNA expression, detected by in situ hybridisation, was greater (P < 0.05) in the ARC in heifersthat gained 1 kg/day of body weight (high-gain, HG; n = 6) compared to heifers that gained0.5 kg/day (low-gain, LG; n = 5). The number of KISS1-expressing cells in the middle ARC was reduced (P < 0.05) in HG compared to LG heifers. In Experiment 2, double-immunofluorescence showed limited aMSH-positive close contacts on GnRH neurones, and the magnitude of these inputs was not influenced by nutritional status. Conversely, a large number of kisspeptin-immu-noreactive cells in the ARC were observed in close proximity to aMSH-containing varicosities. Furthermore, HG heifers (n = 5) exhibited a greater (P < 0.05) percentage of kisspeptin neuronesin direct apposition to aMSH fibres and an increased (P < 0.05) number of aMSH close contactsper kisspeptin cell compared to LG heifers (n = 6). These results indicate that the POMC-kisspeptin pathway may be important in mediating the nutritional acceleration of puberty inheifers.
