Abstract: 【Objective】 This study was aimed to provide a scientific basis for the germplasm characteristics of Xupu geese and their hybrid utilization by comparing the liver tissue,intestinal morphology and intestinal flora in different breeds of goslings. 【Method】 A total of 60 healthy goslings each of Xupu geese,Landes geese and hybrid geese (Xupu geese ♂ × Landes geese ♀) without feeding after hatching were selected,half male and half female,with 6 replicates in each breed and 10 per replicate.After slaughter,the basic indicators were measured,liver and intestinal samples were taken to determine the tissue morphology,and intestinal floras were determined. 【Result】 The intestinal lengths of Landes geese and hybrid geese were significantly higher than those of Xupu geese (P<0.05).The numbers of fat droplets and vacuoles in liver sections of Xupu geese were lower than those of Landes geese and hybrid geese,the crypt depths of duodenum and ileum were significantly higher than those in Landes geese and hybrid geese (P<0.05),and the villus height/crypt depth ratios of duodenum and ileum were significantly lower than those in Landes geese and hybrid geese (P<0.05).The ACE index and Chao index of hybrid geese were significantly higher than those of Xupu geese and Landes geese (P<0.05),and the cecal intestinal flora was richer than that of the other two breeds at the phylum and genus levels. 【Conclusion】 The breed factor had significant effects on liver tissue,intestinal morphology and intestinal flora of goslings,among which the hybrid goslings showed significant hybridization advantages.The results provided a reference basis for germplasm characteristics,intestinal flora regulation and subsequent production of goose fatty liver in Xupu geese.
