متن کاملFatty Acid Prof iles of Ram's Sperm after Removing Some Fatty Acid Sources from the Diets and Persistency of Fatty Acids in Sperm
BACKGROUND Mammalian spermatozoa are characterized by a high proportion of polyunsaturated fatty acids (PUFAs), but reliable data concerning dietary effects on fatty acid (FA) profile in ram's sperm and the persistency of FA in the ration to the FA in sperm has not been reported. Therefore, the aim of this study was to determine the stability of saturated and unsaturated FAs in ram's sperm desp...
متن کاملO-16: Metabolism of Exogenous Fatty Acids, Fatty Acid-Mediated Cholesterol Efflux, PKA and PKC Pathways in Boar Sperm Acrosome Reaction
Background: For understanding the roles of fatty acids on the induction of acrosome reaction which occurs under association of cholesterol efflux and PKA or PKC pathways in boar spermatozoa, metabolic fate of alone and combined radiolabeled 14C-oleic acid and 3H-linoleic acid incorporated in the sperm was compared, and behavior of cholesterol and effects of PKA and PKC inhibitors upon fatty aci...
متن کاملEffects of diets enriched in different sources of fatty acids on reproductive performance of Zel sheep
The present study evaluated the effects of diets enriched in saturated and polyunsaturated fatty acids (n-3and n-6) on reproductive indices, metabolic hormones and metabolites prior to ram introduction in oestrussynchronized ewes. Zel ewes (n=188) were assigned to 4 groups. Ewes in the control group (CON) did notreceive fat. Ewes in the 3 other groups received 3% oil/DM/day of palmolein oil (PL...
متن کاملSperm quality parameters and fatty acid composition in Farahani rams fed pistachio by-products
Fifteen fertile rams (live weight 55.9 ± 1.21 kg, and 2.5-3 years old) were randomly allotted to three diets consisting of 0 (Control), 12.5 (PBP-12.5), and 25 % (PBP-25.5) pistachio by-products (PBP) in dry matter. Sperm motility parameters were detrimentally affected in animals feeding on PBP-25% diet (P<0.05). Sperm concentration of C17-1, C22-6-n-3, C18-2-Cis and C22-6 n-3 fatty acids decre...
متن کاملSupplementing Fatty Acids to Improve Sperm Characteristics
Artificial insemination via cooled or frozen-shipped semen allows more mares to be bred to a single stallion, but not all stallions produce semen capable of withstanding the cooling and freezing procedures. Aurich et al. (1996) estimated that cooled or frozen-shipped semen achieves < 75% of the pregnancy rates achieved with fresh semen. Some factors affecting the fertility rates of thawed semen...
