(Method)1920 only randomly divided into four groups of white wing Pigeon, each group of four groups in the diet, respectively, and add 0.01%, 0.02%, 0.03% xylooligosaccharides, the group and blank. (Result)Results showed that 0.02% and 0.03% xylooligosaccharides laying rate group were significantly(P0.05)higher than the average daily control and egg are significantly(P0.01) higher than the total weight of each other in the total weight of eggs and feed/egg ratio were significantly(P0.01)higher than the average daily control. Egg quality comparison analysis results show that:the eggs yolk and eggshell percentage, eggshell thickness, the Hamiltonian units, the difference was not significant(P0.05), shell strength has obvious increases(P0.05). (Conclusion)0.02% and 0.03% of xylooligosaccharides were supplemented in the pigeon egg based diet, they were increased 8.73% and 4.99% raise benefit than the blank control group, respectively.
