摘要
用8只绿头野鸭公鸭与50只天府肉鸭母鸭自然交配生产F1代，测定父母本和F1代的生长速度和9周龄屠体性状。结果发现，种蛋受精率为80.5％，F1代成活率100％，6～7周龄体重1242.0～1362.0 g，比绿头野鸭提前5～6周上市。F1代各项屠体指标比绿头野鸭高1倍以上，尤其是胸肌重比绿头野鸭高178.3％，而且腹脂率显著低于天府肉鸭。
：Eight male wild mallards cross to 50 meat breed of Tianfu ducks by natural service to produce F1.Growth rate and meat performance of the two breeds and their F1 are determined in the study.The result shows that F1 have a rapid growth rate compared to wild mallards,i.e.the liveweight of F1 at age 6～7 weeks is 1242.0～1362.0 g,and this marketing age is 5～6 weeks earlier than wild mallards.Meat performance of F1 in termed of liveweight,dressed weight,eviscerated weight,breast muscle and leg muscle yield at age of 9 weeks has increased at least 1－fold,and especially breast muscle yield of F1 has increased by 178.3％compared to the wild mallards.Fat content of F1 meat is much lower than that of Tianfu ducks.
