[ 2 ] - P-1: Addition of Omega-3 Unsaturated Fatty Acids in Sperm Extender Does Not Improve The Quality of Chilled Bovine Sperm
Background: The importance of polyunsaturated fatty acids (PUFAs) on chilled sperm quality is under investigation. Addition of fatty acids to the diet can influence sperm quality and male fertilizing capacity. The aim of this study was to investigate if the addition of n-3 PUFAs improves quality of bovine chilled sperm. Materials and Methods: In order to do experiment, 5 proven bulls were rando...
[ 3 ] - P-110: Effect of Increasing Amount of Oocyte Secreted Factors on Cumulus Expansion of Bovine Cumulus-Oocyte Complexes
Background: In vitro maturation is a good method to decrease cancer risk of superovulation by gonadotropin hormones. A paracrine effect of oocyte secretions on oocyte developmental competence is under investigation. Apart from oocyte maturation, ovulation in vivo requires a precise control of extracellular matrix modification. Cumulus cells secrete hyaluronan to form a muco-elastic extracellula...
[ 4 ] - P-138: The Effects of Omega-3, 6, 9 Fatty Acids on The Quality of Bovine Chilled Semen
Background: Many studies are being conducted to improve the quality of bull sperm in storage conditions. It seems that increasing sperm membrane unsaturated fatty acids can enhance sperm quality. This study was aimed to investigate the effects of combination of omega- 3, 6, 9 fatty acids on characteristics of bovine chilled semen. Materials and Methods: Different levels of oil containing omega-...
[ 5 ] - P-1: Leptin mRNA Is Present in Bovine EpididymalSpermatozoa
Background: The present study aimed to investigate the presence of leptin mRNA transcript in epididymal spermatozoa of Holstein cattle by RT-PCR analysis. Materials and Methods: To collect sperm from epididymis, the whole testes of three adult Holstein bulls were quickly removed after slaughtering. Samples were transferred to the laboratory on ice and subsequently the epididymal contents were c...
