Abstract:

The experiment aimed to compare the differences in egg production and stress resistance among four duck breeds: Shaoxing Duck, Youxian Ma Duck, Shan Ma Duck, and Jinyun Ma Duck. This study compared and analyzed the egg production performance of these four duck breeds in China. The results showed that Youxian Ma Duck started laying eggs earliest (116.71 days), and it was significantly earlier than Shaoxing Duck, which started laying eggs latest. Shan Ma Duck had the highest egg production at 43 weeks of age, significantly higher than the other three breeds. The order of egg production at 66 weeks of age, from highest to lowest, was Shan Ma Duck, Shaoxing Duck, Jinyun Ma Duck, and Youxian Ma Duck. At 24 weeks, the egg production rate of all ducks gradually entered the peak period. Starting from 49 weeks, the egg production rate of all four breeds might experience a concentrated decline due to weather changes and stress. By the 57th week, the egg production rate of Shaoxing Duck and Shan Ma Duck recoverd to 90.7% and 91.7%, respectively, indicating that they had better stress resistance. Jinyun Ma Duck had the poorest stress resistance. The average egg production rates of Jinyun Ma Duck, Shan Ma Duck, Shaoxing Duck, and Youxian Ma Duck from 16 to 69 weeks were 70.7%, 71.9%, 72.7%, and 69.0%, respectively. In conclusion, Shan Ma Duck performed excellently in terms of age at first egg, egg production quantity, and stress resistance. Shaoxing Duck started laying eggs at a later age but had a higher egg production rate in the later stage. Youxian Ma Duck started laying eggs earliest but had the poorest stress resistance. Jinyun Ma Duck had a moderate level of age at first egg and overall egg production quantity, with excellent stress resistance.
