The study was conducted to determine the semen characteristics of three genotypes of Nigerian Indigenous cocks. Thirty Six (60) local breeding cocks comprising of 20 frizzle, 20 normal and 20 naked neck selected randomly from the poultry breeding unit of the Ambrose Alli University Teaching and Research farm was used for this study. Semen were collected from them by abdominal massage and analyzed for semen characteristics. Semen concentration were significantly higher in normal 21.18±0.03mL (p<0.05) than in frizzle feathered 20.19+0.093. and normal and naked neck feathered genotype 18.07±0.163. Sperm motility was significantly better (p<0.05) in naked neck feather than in frizzle feather. Semen volume of the frizzle and normal feathered, were significantly higher (p<0.05) than naked neck. Variations on semen characteristics abound in the three Nigerian indigenous cocks compared. Key words: Indigenous cocks, morphological defects, semen characteristics
