    abstract = {The purpose of this study was to evaluate tshe optimum number of spermatozoa for highest fertility in Ross-308 broiler breeder chicken. About 24 Ross hens in 4 treatment groups were used. Semen was collected from 8 Ross roosters by abdominal massage and pooled in glass tube. After initially dilution with modified Ringer&#146;s solution and determination the spermatozoa concentration by hemocytometer, the semen was diluted further. About 50, 75, 100 and 150 million spermatozoa in 0.1 mL were inseminated to treatment groups for 4 weeks (4 times repeating). Eggs were collected daily from the 2nd day post insemination and incubated. After 7 days of incubation, the eggs were candled for fertility rate. In treatment groups that were inseminated with 50, 75, 100 and 150 million spermatozoa, fertility rates were 52.85&plusmn;4.15, 72.37&plusmn;5.28, 87.64&plusmn;4.81 and 89.12&plusmn;3.74%, respectively. As shown to this results, fertility rate in treatment group that was inseminated with 50 million spermatozoa was lowest (52.85&plusmn;4.15%) and then increased significantly (p&lt;0.05) with increasing the sperm number and reached to maximum in treatment group that was inseminated with 100 million spermatozoa (87.64&plusmn;4.81%). Difference of fertility rate between treatment groups that were inseminated with 100 and 150 million spermatozoa (87.64&plusmn;4.81 and 89.12&plusmn;3.74%, respectively) was not significant (p&gt;0.05). It is concluded that optimum dose of spermatozoa for artificial insemination in Ross-308 chicken was 100 million sperm.}
