摘要/Abstract

摘要： 选用3只安装永久瘤胃瘘管的甘肃高山细毛羯羊(1.5岁,平均体重22.5kg),采用3×3拉丁方设计,研究3种组合饲粮,即对照饲粮(Ⅰ)、含甜菜渣饲粮(Ⅱ)、含苹果渣饲粮(Ⅲ)对绵羊消化代谢的影响。试验分3期,每期预试期10d,正试期9d。结果表明,饲粮Ⅰ、Ⅱ的干物质(DM)和有机物质(OM)消化量与消化率均显著高于Ⅲ(P＜0.05);饲粮Ⅱ的中性洗涤纤维(NDF)和酸性洗涤纤维(ADF)消化量及消化率呈现出高于Ⅰ、Ⅲ的趋势(P＞0.05),饲粮Ⅲ的NDF和ADF消化率也呈现出低于Ⅰ的趋势;饲粮Ⅱ的氮消化量显著高于Ⅰ(P＜0.05),其消化率显著高于饲粮Ⅰ、Ⅲ(P＜0.05),呈现出其氮存留量高于Ⅰ及氮存留率高于Ⅰ、Ⅲ的趋势;饲粮Ⅱ钙的表观消化率显著高于Ⅰ(P＜0.01)、Ⅲ(P＜0.05),Ⅲ也显著高于Ⅰ(P＜0.05);饲粮Ⅲ的磷表观消化量显著高于Ⅰ、Ⅱ(P＜0.05),且呈现饲粮Ⅲ磷消化率高于Ⅱ,Ⅱ也高于Ⅰ的趋势。

Abstract: Three one and a half year old Gansu high mountain fine wool wethers (average live weight 22.5 kg) were fitted with permanent ruminal fistulas and a 3×3 Latin square design was used to study the effects of three combinations of diet (Ⅰ control, Ⅱ with 8% beet pulp, and Ⅲ with 8% apple pomace) on apparent digestion and retention of nitrogen. There were three 19 day periods (a 10-d adjustment followed by 9-d of collections) for each period. Apparent digested DM, OM and digestibility of DM and OM of wethers fed with diets Ⅰ andⅡ were significantly greater than those of Ⅲ (P＜0.05). The digested NDF, ADF and the digestibility of NDF and ADF in dietⅡ were greater than those of dietⅠ, while those of diet Ⅲ were lower by comparison with these of diet Ⅰ. The digested N of diet Ⅱ was significantly (P＜0.05)greater than that ofⅠ and N digestibility of Ⅱ was significantly (P＜0.05) greater than those of Ⅰ and Ⅲ. There was more retained N of Ⅱ than of Ⅰ and Ⅲ. The apparent digestibility of Ca for diet Ⅱ was significantly (P＜0.01) greater than those ofⅠand of Ⅲ(P＜0.05), and that of Ⅲ was significantly greater than that of Ⅰ. The digested P of diet Ⅲ was (P＜0.05)significantly greater than those of Ⅰand Ⅱ. The apparent digestibility of P in diet Ⅲ was greater compared with Ⅰ and Ⅱ.
