Abstract :This study aimed to investigate the effect of gender on growth performance, live weight gain, and survival rate in Pekin ducks raised in a family-type farm in Kars province. A total of 150 ducklings insert ignore into journalissuearticles values(62 males, 88 females); were observed from day one. Weight measurements were recorded regularly, and mortalities were noted for survival rate analysis. No significant gender differences were observed in live weight up to 10 weeks of age, indicating comparable growth rates initially. However, at 10, 13, and 16 weeks, male ducks had higher live weights compared to females. Daily live weight gains were significantly higher during the first two weeks, with a decreasing trend as the ducks grew older. Gender significantly affected daily weight gains during the initial two weeks. The influence of gender on weekly live weight gains was not statistically significant. Live weight gains decreased over time, while overall live weight increased. Regression models indicated higher growth rates in males. Survival rates remained high throughout the 16-week period, with no significant difference between genders. The hazard ratio analysis suggested no substantial difference in mortality risk between male and female ducks. In conclusion, gender influenced live weight and daily weight gains in Pekin ducks, with males generally exhibiting higher weights. However, gender did not significantly affect average live weight gain and survival rates.
