- Abstract
The purpose of this study was to evaluate the genetic express of select traits by investigating the relationship between the number of fertilized eggs (F) and it's breeding value (FEBV) of the Pekin ducks after 11 generations selection of F. At 29, 32 and 35 weeks of age, eggs were collected for a period of 14 days after Pekin ducks were single artificially inseminated with pooled Muscovy semen, and the F value was calculated for the number of fertile eggs at candling at the 7th day of incubation. The breeding value of the BLUP animal model for the number of fertile eggs was estimated. The results indicated that F EBv increased linearly with F value and followed with polynomial y = 0.0088x² + 0.072x + 2.1731 (y: FEBV, x: F), R² = 0.97, the correlation between F and FEBV was 0.55. The frequency ofF was more than or equal to 5 that was 87.5%, and FEBV of Gll selected ducks was 2.97. In summary, the higher FEBV ducks accompanied with higher F and more likely be selected as parent.
