The 15 Luong Phuong roosters were collected semen every 3 days in the morning. The semen of Luong Phuong roosters, after being collected, was diluted with a preservation solution in Ringer's environment, stored at 4˚C, and the quality of the semen was checked at the Veterinary Diagnostic Laboratory of Tay Do University. The results showed that the semen quality of Luong Phuong roosters had a semen volume of 0.34ml, motility and sperm concentration of 86.52 x 109/ml and 3.59%, respectively and the abnormality rate was 3.66%. The difference in semen quality between the 6-month-old and 8-month-old Luong Phuong roosters was statistically significant with P<
0.05. The semen quality of 8-month-old Luong Phuong roosters shows higher sperm motility and a lower rate of abnormal sperm compared to the 6 month old group. The positive correlation between rooster weight and sperm motility (0.046), and between sperm motility and sperm concentration (0.531). The negative correlation between rooster weight and sperm concentration (-0.153), and between the rate of abnormal sperm and motility (-0.279).
