摘　　要：采用 2个 3× 3拉丁方设计 ,选用 6头杜×长×大阉公猪测定了仔猪对纤维来源和水平不同的日粮的消化率。日粮处理依次为对照组 (不含纤维性饲料 ) ,小麦麸组 (含 5 %小麦麸 )和甜菜渣组 (含 5 %甜菜渣 )。试验结果表明 ,小麦麸组仔猪对干物质、有机物和 ADF的回肠表观消化率显著高于 (P<0 .0 5 )对照组 ,但处理对干物质、有机物的粪消化率没有显著影响。对照组和小麦麸组仔猪纤维素回肠消化率显著高于 (P<0 .0 5 )甜菜渣组 ,半纤维素粪消化率显著低于 (P<0 .0 5 )甜菜渣组。小麦麸组仔猪的回肠总能消化率显著高于(P<0 .0 5 )甜菜渣组 ,但不同处理的总能粪消化率没有显著差异 (P>0 .0 5 )。小麦麸组回肠蛋白质消化率显著高于 (P<0 .0 5 )对照组。甜菜渣组的粪氮消化率显著高于 (P<0 .0 5 )对照组。日粮处理对能量和氮的代谢率、15种氨基酸回肠表观消化率没有显著影响 (P>0 .0 5 )In an experiment with two 3×3 Latin square design, six Duroc×Langdrance×Largewhite castrates were used to investigate the effects of dietary fiber sources and level on nutrient digestibility and utilization in piglets. The treatment was CONTROL (no fibrous feedstuff), WB (contain 5% wheat bran) and SBP (contain 5% sugar beet pulp). The results showed that WB piglets had higher ileal digestibility of dry matter, organic matter and ADF than that of CONTROL piglets ( P <0.05), but treatment did not significantly influence the fecal digestibility of dry matter and organic matter ( P >0.05). Piglets of WB and CONTROL had greater ileal digestibility of cellulose and lower fecal digestibility of hemicellulose than that of SBP piglets ( P <0.05). WB piglets had greater ileal nitrogen digestibility than CONTROL piglets ( P <0.05) and greater ileal energy digestibility than SBP piglets ( P <0.05). SBP Piglets had greater fecal nitrogen digestibility ( P <0.05) than CONTROL pigs. Treatment did not significantly influence metabolizability of gross energy, nitrogen or ileal apparent digestibility of 15 amino acids ( P >0.05).
