Abstract: In order to study the effect of lactic acid bacterium on liver performance, fat deposition, slaughter performance, nutrient apparent digestibility and serum biochemical indices of Landes geese, a total of 108 12-week-age healthy Landes geese were selected and randomly divided into 3 groups with 6 replicates per group and 6 geese per replicate.The geese in control group were fed with the diets without lactic acid bacterium during the whole experiment, and the geese in groups A and B were fed with the diets supplemented with 2 000 and 3 000 g/t lactic acid bacterium during 1 to 5 d, respectively;With 3 000 and 5 000 g/t during 6 to 15 d, respectively;And with no lactic acid bacterium during 16 to 25 d.The results showed that compared with the control group, supplementation of lactic acid bacterium could prolong the mature period of liver (P<0.05) and decrease the elimination rate of Landes geese.Compared with the control group, supplementation of lactic acid bacterium could decrease the rate of fat on liver, the average weight of liver, liver weight/weight of bowel and abdominal fat and liver weight/weight gain in group B were significantly decreased (P<0.05).There were no significant differences in slaughter performance among all groups (P>0.05).Compared with the control group, the apparent digestibility of crude fat in group B was significantly increased (P<0.05), the apparent digestibility of calcium and phosphorus in groups A and B were significantly increased (P<0.05).Compared with the control group, the serum content of triglyceride, cholesterol and very low density lipoprotein in groups A and B were significantly decreased (P<0.05).In conclusion, diets with lactic acid bacterium were good to geese, but considering its prevention of fat deposition in liver, lactic acid bacterium was suggested not to be used in force-feeding process.
