Effects of Different Proportions of Silage Ramie Instead of Basal Diet on Growth Performance, Intestinal Development, Nutrient Apparent Metabolic Rate and Serum Biochemical Indices of Landes Geese
摘要
Abstract
This experiment was conducted to study the effects of different proportions of silage ramie instead of basal diet on growth performance,intestinal development,nutrient apparent metabolic rate and serum biochem-ical indices of Landes geese. A total of 360 healthy 21-day-old Landes geese with similar body weight were randomly selected and allocated to 5 groups with 9 replicates per group and 8 geese per replicate. Geese in the group Ⅰ(control group)were fed a basal diet, and the others in the test groups(groups Ⅱ to Ⅴ)were fed with the experimental diets which made silage ramie replacing the basal diet according to the proportions of 20%,30%,40% and 50%, respectively. The results showed as follows:1)the average daily feed intake of geese of groups ⅡtoⅤwas significantly higher than that of groupⅠ(P<0.05),and the ratio of feed to gain of geese of groups Ⅲ, Ⅳ and Ⅴ was significantly higher than that of group Ⅰ(P<0.05). In addition, the highest average daily gain of geese was obtained in the groupⅡ,but there was no significant difference in av-erage daily gain of geese among all groups(P>0.05). 2)There were no significant differences in total intesti-nal length, duodenal length,jejunum+ileum length,cecum length and intestinal weight of geese among all the groups(P>0.05). In addition, the villus height and villus height/crypt depth in ileum of geese of group Ⅱwere significantly higher than those of group Ⅰ(P<0.05). 3)The apparent metabolic rates of gross energy and crude protein of geese of groupⅠwere significantly higher than those of other groups(P<0.05),the ap-parent metabolic rate of ether extract of geese of groups Ⅰ and Ⅲ was significantly higher than that of other groups(P<0.05), the apparent metabolic rate of crude fiber of geese of groups Ⅲ and Ⅴ was significantly higher than that of other groups(P<0.05). 4)There were no significant differences in the contents of total protein, albumin, globulin, glucose, total cholesterol and urea of geese among all groups(P>0.05). To sum up, under these experimental conditions, based on the evaluation of growth performance, nutrient apparent metabolic rate,intestinal development and serum biochemical indices of Landes geese,the results show that si-lage ramie replacing the basal diet according to the proportion of 20% is appropriate.关键词
