摘要
Abstract
This experiment was conducted to investigate the effects of dietary metabolisable energy level on laying performance of Cherry Valley breeding ducks. A total of 4 980 healthy Cherry Valley breeding ducks aged 29 weeks were randomly divided into 5 groups with 3 replicates in each group, and 332 ducks in each replicate. Each replicate contained 57 male ducks and 275 female ducks. The ducks in the 5 groups were fed experimental diets containing different levels of metabolisable energy, which were 11. 08, 11. 29, 11. 50, 11. 71 and 11.92 MJ/kg, respectively. The experiment lasted for 19 weeks (29 to 47 weeks of age). The results showed as follows: there were no significant differences in laying rate, egg number each and qualified egg number each among all groups (P >0. 05). When the metabolisable energy level was 11. 29 MJ/kg, the breeding ducks had the highest laying rate, egg number each and qualified egg number each.. Meanwhile, the dietary metabolisable energy level had significant effects on the qualified egg rate and malformed egg rate (P < 0.05). With increasing the dietary metabolisable energy level, the qualified egg rate was linearly decreased (P <0. 05) , while the malformed egg rate was linearly increased (P <0. 05). No significant differences in broken egg rate and double yolk egg rate were found among all groups (P > 0. 05) , while the lowest broken egg rate and double yolk egg rate were all found in the group with the diet containing 11.29 MJ/kg metabolisable energy. With increasing the dietary metabolisable energy level, the fertilization rate was decreased in a quadratic curve (P <0.05) , while the mortality rate was linearly increased (P <0. 05). In conclusion, when dietary metabolisable energy level is from 11. 08 to 11. 29 MJ/kg, the Cherry Valley breeding ducks have a better laying performance.
