摘　　要：用 1日龄艾维因 (Avian)公雏 16 8只进行试验 ,研究日粮添加壳聚糖对肉仔鸡生长性能、脂肪代谢的影响。试鸡按体重随机分为 4组 ,每组设 2个重复 ,分别饲以含壳聚糖 0、 1%、 2 %、 3%的日粮 ,试鸡自由采食和饮水。试验分 0～ 2 1d、 2 2～ 4 2 d、 4 3～ 5 6 d 3个阶段共 5 6 d,在第 2 1d、 4 2 d、 5 6 d对试鸡称重 ,每组选取 3只体重接近平均体重的鸡进行心脏采血 ,然后屠宰。试验结果表明 ,添加壳聚糖能促进肉仔鸡的生长 ,能显著降低腹脂 (P<0 .0 1)、皮下脂肪 (P<0 .0 5 )、肌间脂肪 (P<0 .0 5 )的沉积 ;能显著减少血清甘油三酯 (P<0 .0 5 )、总胆红素的含量 (P<0 .0 5 ) ,减少脂肪的吸收。试验结果表明 ,壳聚糖能降低肉仔鸡的脂肪沉积量 ,对改善胴体品质有益。One hundred and sixty\|eight 1\|day\|old Avian broiler chickens were randomly allocated into four groups with two replicates for a three\|phase trial(0-3 week,4-6 week,7-8 week).The experiment involved four dietary levels of chitosan supplement(control:0;Treat 1:1%,Treeat 2:2% ,Treat 3:3%).All birds received feed and water freely.On the last day of every phase, 3 broilers from each replicate were selected for determining lipometabolism.The results showed that chitosan had a significant effect on the improvement of ADGW(average daily gain weight)( P <0 01),the decrease of PDAF(percentage of dissected abdominal fat )( P <0 01),SFD(subcutaneos fat depth)( P <0 05),IMFD(intermuscular fat depth) ( P <0 05),TG(triacylglycerol),TBIL(total bilirubin)( P <0 05).The results implied that chitosan could effectively decrease fat deposition and improve carcass trait.
