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.
