【摘要】：为探讨凤头性状对凤头白鸭生产性能的影响,本研究比较不同凤头大小的凤头白鸭体重、体尺等生长性能,以及产蛋数、受精率、入孵蛋孵化率、健雏率等繁殖性能,并对其后代生长发育性能进行了跟踪。结果显示:凤头大小对凤头白鸭体重、体尺无显著影响(P0.05),但凤头大小对总产蛋数、受精率以及入孵蛋孵化率的影响均较大,且凤头越大产蛋数越高,但大型凤头组的受精率和入孵蛋孵化率均显著低于中、小型凤头组(P0.05),而凤头大小对后代的健雏率影响不大;不同凤头大小的凤头白鸭群体的后代体重在4周龄前差异较大,三组后代的体重在2~4周龄增长最快,8~10周龄最慢,但6、8、10周龄体重均差异不显著(P0.05)。
[Abstract]:In order to study the effect of the traits of the female head on the production performance of the white duck, the reproductive performance of the white duck with different sizes, such as body weight, body size, egg number, fertilization rate, hatching rate and brooding rate, was compared. The growth and development performance of its offspring was followed up. The results showed that the size of chicken head had no significant effect on the body weight and body size of the white duck, but the size of the head had a great effect on the total egg number, fertilization rate and hatching rate, and the larger the number of eggs was, the higher the egg number was. However, the fertilization rate and hatching rate of hatched eggs were significantly lower in the large Fengtou group than those in the middle one. The litter size of the small Fengtou group had little effect on the healthy brooding rate of the offspring, and the weight of the offspring of the white duck population with different size had a significant difference before 4 weeks of age. The body weight of the offspring of the three groups increased most slowly at the age of 2 ~ 4 weeks, but there was no significant difference in the body weight of all the three groups at the age of 8 ~ 10 weeks (P < 0.05).
