Effects of crude fiber levels on production performance, organ index and serum biochemical parameters of Dingan geese aged from 1 to 28 days.

[Objective] The paper was to investigate the effects of dietary crude fiber level on production performance, organ index and serum bio-chemical parameters of Dingan geese aged from 1 to 28 days. [Method] A total of 144 1-day-old Dingan geese with the same genetic background and similar initial weight(88.75±0.21 g) were randomly assigned into 3 groups with 4 replicates per group and 12 geese per replicate, and fed with the diets containing 2.56%, 3.52% and 4.48% crude fiber, respectively. The trial lasted 28 d. [Result] 1) The final weight and daily gain of 3.52%CF group were significantly higher than those of 2.56% CF group(P 0.05). 3) As the dietary crude fiber levels rose, the abdominal fat rate showed a downward trend( P>0.05). 4) The liver index of 3.52%CF group was significantly higher than that of 2.56% CF group(P 0.05), but the serum uric acid level was lower(P>0.05). [Conclusion] When the crude fiber level was 3.52 %, the production performances of Dingan geese aged from 1 to 28 days were better, and the liver index and serum albumin level could be obviously improved.
