چکیده انگلیسی
The aim of the present experiment was to study the effect of fish oil and Vitamin E rich diets on semen production, sperm functions and composition in broiler breeders. The following parameters were measured: semen volume and concentration, sperm motility and viability, sperm susceptibility to induced peroxidation, sperm lipid and α-tocopherol contents. Dietary n â 3 PUFA were successfully transferred into spermatozoan phospholipid by fish oil feeding according to the following main features: (a) the C22:6n â 3 and C22:5n â 3 contents were increased, but C22:4n â 6 remained the peculiar and major polyunsaturate; (b) the content and proportion of total PUFA did not change; (c) the proportional increase of n â 3 PUFA was compensated by the decrease of n â 6 PUFA, an increase in the proportion of n â 9 fatty acids was also found. The sperm content of α-tocopherol was doubled increasing the dietary availability of the vitamin to 300 mg/kg of feed. The specific n â 3 PUFA and Vitamin E enrichment of chicken sperm affected cell functions. Significant interactions between the two treatments were also found for some parameters. The best sperm quality condition in control sperm (rich mainly in n â 6 PUFA) was found supplying 200 mg Vitamin E/kg of feed to the male breeders, and in contrast in n â 3 rich sperm supplying 300 mg Vitamin E/kg.
