摘要(Abstract):

[Objective] The study was carried out to investigate the effects of dietary crude fiber on growth performance and serum biochemical in-dex of Dingan geese aged from 35 to 70 days. [Method] A total of 120 Dingan geese on day 28 with the same genetic background and similar initial weight(1 384.83.73±0.76 g) were randomly assigned into 3 groups, with 4 replicates per group and 10 geese per replicate. Geese were fed the diets containing 4.29%, 5.29% and 6.29 % crude fiber, respectively. The experiment lasted 35 d. [Result] Final weight and daily gain of 5.29 %CF group were significantly higher than those of 6.29 % CF group(P<0.05); Feed intake was markedly higher than those of 4.29% and 6.29 % CF groups(P<0.05); Feed gain ratio was significantly lower than that of 6.29 % CF group(P<0.05). Compared with 4.29% and 6.29 % CF groups, serum albumin concentrations of 5.29 % CF group increased significantly(P<0.05), while serum total protein and globin contents were higher(P>0.05), but serum uric acid level was lower(P>0.05). [Conclusion] 5.29 % crude fiber could lead to higher growth performance of Dingan geese.
