早稻谷及全早稻日粮主要营养物质表观消化率测定研究

A Study on Testing the Apparent Digestabilities of Main Nutrients in Paddy and Wholly Paddy-typed Ration

添加玉米型预混料配方的早稻谷（ 早稻谷Ⅰ） 及全早稻日粮（ 全早稻日粮Ⅰ） 和添加全早稻型预混料配方的早稻谷（ 早稻谷Ⅱ） 及全早稻日粮（ 全早稻日粮Ⅱ） ，全粪法猪体消化试验测定他们的主要营养物质消化率。试验结果表明：早稻谷单一饲料和全早稻日粮，早稻型预混料处理较普通玉米型预混料处理，能量、粗纤维消化率都有显著提高（ Ｐ＜ ０ ．０５） ，同时全早稻日粮粗蛋白和无氮浸出物的消化率也显著提高（ Ｐ＜ ０ ．０５） 。

Four treatment groups were arranged to test the digestabilities of the main nutrients in paddy and wholly paddy-typed rations treated with corn-typed premix (paddy Ⅰ group and wholly paddy-typed ration Ⅰ group) and wholly paddy-typed premix (paddy Ⅱ group and wholly paddy-typed ration Ⅱ group) by means of pig digestive trials with a method of fecus-collected wholly. The results indicated that: compared with corn-typed premix treatment groups, the digestabilities of total energy and CF in single paddy feed group or in wholly paddy-typed ration group treated with wholly paddy-typed premix had a significant improvement (P<0.05), meanwhile the digestabilities of CP and NF in wholly paddy-typed ration group had a significant improvement, too (P< 0.05).
