摘要: 采用8头初始体重平均为27.2 kg± 2.3 kg、在回肠末端装有简单T型瘘管的杜长大三元杂交公猪,手术康复后随机分成2组,每组4头,每组采用同一豆粕玉米淀粉基础日粮,按拉丁方设计,用于测定豆粕、棉粕、菜粕、稻谷、油糠、统糠和玉米7种饲料原料的回肠和粪氨基酸消化率。结果表明,所测氨基酸平均表观消化率回肠比粪低5%~8%(P<0.05);稻谷氨基酸表观消化率比玉米低5%;所测原料氨基酸表观消化率与中国饲料数据库和前人报道结果基本吻合。

Abstract: To determine the amino acid digestibility of oil-extracted soybean, cotton and rape seeds, as well as that of rice grain, corn, rough rice bran, and defatted rice bran fed to pigs, a total of eight crossbred boars with an average initial weight of 27.2 kg±2.3 kg were equipped with simple T-shape cannula in their ileum, randomly divided into two groups, and fed with the same basal diet of soybean corn starch. The results showed that the average apparent amino acid digestibility of tested feedstuffs was basically in accordance with that of recently published data and China Feed Database. The apparent ileal amino acid digestibility was lower than the apparent fecal amino acid digestibility by 5%-8%, and the apparent amino acid digestibility of rice grain was 5% lower than that of corn. In rice-producing region, it’s more benefit to replace rice grain with rough rice bran and defatted rice bran to feed pigs.
