Evaluation of semen quality in Luong Phuong roosters at 6 and 8 months of age

Abstract

The study was conducted on 15 Luong Phuong roosters aged 6 - 8 months, raised at the experimental chicken farm of Tay Do University, to evaluate the semen quality of Luong Phuong roosters from March to May 2024. 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).
