The Level of Hormone Testosterone, Sperm quality, Testes and Uropygium size of Male Quails (Coturnix coturnix japonica) Based On Differences Age

Abstract

The research was conducted to know The level of hormone testosterone, sperm quality, testes and uropygium size of
male quails (coturnix coturnix japonica) based on differences in age. The research used each forty 4-w old male
quails, 6-w old male quails, 8-w old male quails and 10-w old male quails. The quails were given feed with the same
composition of diets are crude protein (20.51%), fat (4.46%), crude fiber (4.38%), calcium (1.54%), phosphor (0.77%)
and energy metabolism (2602.01 Kcal/kg). The quality of the quail feed material, it is analyzed the proximate of the
ration (corn, rice bran, soya bean meal, meat bone meal, CaCO3, DL-metionin, L-lysine, NaCl and premix). Variables
observed: hormone testosterone level, body weight, sperm quality (motility, morphology, viability and concentration),
testes size (weight, length, circulation and volume), and uropygium size. The sperm quality data (sperm motility, sperm
morphology, sperm viability and sperm concentration) were analyzed by Duncan Multiple Range Test (DMRT). The
other data were analyzed descriptively. The output of this research showed that: The average of hormone testosterone
level of forty 6, 8 and 10-w 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-w old quails. The average body weight of forty 4-w old quails (55.8 g), forty 6-w old
quails (103.0 g), forty 8-w old quails (135.0 g) and forty 10-w old quails (152.0 g). The highest sperm quality showed at
forty 10-w 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-w old
quails not significance difference. The highest testes size and uropygium size showed at forty 10-w old quails with the
average of testes weight (2.64 g); uropygium (2.90 g), testes length (2.0 cm), testes circle (4.7 cm), testes volume (2.0
ml) and uropygium diameter (5.70 cm). The lowest testes and uropygium size showed at forty 4-w old quails. Testes
and uropygium size of forty 6 and 8-w old quails not significance difference. The conclusion of this research: the level
of hormone testosterone, sperm quality, testes and uropygium size of forty 6 to 10-w old male quails have higher quality
rather than forty 4-w old male quails and the highest quality showed at forty 10-w old male quails.

Key words: Hormone testosterone, sperm quality, testes, uropygium, male quails
