摘　　要：为研究壳聚糖对肉鹅生产性能及养分代谢的影响,选28日龄健康肉鹅120只,随机分成4组,每组5个重复,每个重复6只。对照组饲喂基础日粮,试验组分别饲喂基础日粮中添加0.05%、0.10%、0.15%壳聚糖的试验组日粮,试验期42 d。结果表明：肉仔鹅日粮中添加0.05%～0.15%的壳聚糖对其生长和饲料利用没有明显的影响;可明显抑制脂肪的消化吸收,纤维的消化不受影响,但有益于蛋白的消化利用,干物质消化率有所降低。添加0.10%的壳聚糖明显降低血清甘油三酯和胆固醇含量。The experiment was aimed to study the effects of chitosan on performance and nutrient utilization in goose. 120 twenty-eight-day-old geese were randomly divided into 4 groups with 5 replicates, each replicate with 6 birds. Control group was fed with the basal diets, while the experimental groups were fed with the basal diet added with 0.05, 0.10, and 0.15% of chitosan for 42 days. Results showed that the addition of 0.05 % ～0.15 % chitosan had no influence on goose growth and feed utilization （P〈0. 05）, but the fat utilization was significantly （P〈0.05） impaired. The digestion of fibre was not affected （P〉0. 05）, while dry matter digestibility decreased （P〈0. 05） by chitosan supplementation. Addition of chitosan showed the positive effect on nitrogen utilization. The addition of 0. 10% chitosan significantly lessened the contents of serum cholesterol and triglyceride.
