SPERM QUALITY, TESTOSTERONE LEVEL, TESTES AND UROPYGIUM SIZE OF QUAIL (COTURNIX JAPONICA) BY SAME FEED INGREDIENTS FED BASED ON AGE AND BODY WEIGHTA. FITRIYAH, SUPRIYONO AND ISYATURRIYADHAH
The highest sperm quality was observed at forty 10-week old quails with the average of sperm motility (78.30%), sperm morphology (76.70% of sperm normal), sperm viability (73.19% of sperm life) and sperm concentration (250 x 109/ mL). Sperm quality of forty 4, 6 and 8-week old quails, show there is no significant difference. The average of hormone testosterone level of forty 6, 8 and 10-week old quails are (1.68 ng/mL), (3.08 ng/mL) and (4.92 ng/mL), and the lowest hormone testosterone level showed at 4-week old quails.

The lowest testes and uropygium size showed at forty 4-week old quails. The quality of sperm, the level of hormone testosterone, testes and uropygium size of forty 6 to 10- week old male quails have higher quality than forty 4-week old male quails, and the highest quality was observed at forty 10-week old male quails.
