effects of dietary N-3 and N-6 polyunsaturated fatty acids on fatty acid composition and fertility of spermatozoa in roosters

Effects of n-3 or n-6 polyunsaturated fatty acids alone or in combination with vitamin E on male breeders' fatty acid composition of spermatozoa, fertility and lipid peroxidation were studied. Fish oil increased C22:6 n-3 and decreased C22:4 n-6 in the spermatozoa [p < 0.05]. Susceptibility of spermatozoa to lipid peroxidation was higher in treatments containing either corn oil or fish oil [p < 0.05]. The fish oil treatments had higher fertility rate compared to the other treatments[p < 0.05].The results of this study suggest that changes in fatty acids profile of roosters's spermatozoa via manipulation of diet is possible and may have significant influence on fertility
