Abstract

This experiment was conducted to study the effects of fermented feed on growth performance, fatty liver performance, intestinal mucosa structure and organ tissue ATPase activity of Landaise geese. A total of 240 seventy-day-old healthy Landaise geese (male) were randomly assigned to 3 groups with 10 replicates per group and 8 geese per replicate. The control group was fed a corn-soybean based diet added 35% water and the experimental groups were fed the basal diets supplemented 1‰ fermentation agent and 35% water to seal fermentation (trial group 1 was fermented for 24 hours and trial group 2 was fermented for 48 hours). One goose of each replicate was selected to slaughter after two weeks, and the other geese were force-feed to produce fatty liver. The results showed as follows: 1) the average daily feed intake in trial group 1 was significantly higher than that in control group (P<0.05). 2) The villus height and villus height/crypt depth (V/C) of duodenum in trial groups 1 and 2 were significantly higher than those in control group (P<0.05); the villus height and crypt depth of cecum in trial group 2 were significantly lower those that in control group (P<0.05), and the V/C of cecum in trial groups 1 was significantly lower than that in control group (P<0.05). 3) The heart Mg2+-ATPase activity in trial groups 1 and 2 was significantly higher than that in control group (P<0.05); the liver Na+,K+-ATPase activity in trial groups 1 and 2 was significantly higher than that in control group (P<0.05), and the liver Mg2+-ATP activity was significantly higher than that in control group (P<0.05). 4) The liver weight and live/carcass in trial group 2 were significantly higher than those in control group in fattening trial period (P<0.05); the live/carcass in trial group 2 was significantly higher than that in control group in force-feeding trial period (P<0.05). In conclusion, the fermented feed can improve the growth performance and the growth and development of villus in duodenum of Landaise geese, also improve the activities of Na+, K+-ATPase and Mg2+-ATPase in heart, fatty liver weight and liver/carcass in the force-feeding trial period of Landaise geese.
