摘 要 选用9 只装有瘤胃和十二指肠近端瘘管的内蒙古白绒山羊羯羊(2 周岁左右) , 随机分成3 组, 分别饲喂氮硫比相同而硫源不同(分别为硫磺、硫化钠和硫酸钠) 的3 种日粮, 进行消化代谢试验和测定食糜流通量, 以探讨不同无机硫对氮和硫的沉积量以及硫的流通规律。试验结果表明: 硫酸钠组氮的进食量和沉积量均显著高于硫磺组和硫化钠组(P < 0. 05) , 但各组间氮的表观消化率差异不显著(P > 0. 05)。硫化钠组和硫酸钠组硫的沉积量以及表观消化率均显著高于硫磺组(P < 0. 05)。硫酸盐在瘤胃吸收量很少, 主要在肠道被吸收; 硫化物在瘤胃和小肠均可被吸收利用; 元素硫(硫磺) 主要在瘤胃和小肠前段被分解利用, 元素硫的生物学效价显著低于硫酸钠和硫化钠(P < 0. 05)。总之, 添加硫酸钠对内蒙古白绒山羊的效果好于硫磺和硫化钠。

ABSTRACT nine fitted with rumen fistula proximal duodenum and the Inner Mongolia Cashmere Goats Jieyang (about 2 years old) were randomly divided into 3 groups, respectively fed nitrogen and sulfur than the same sulfur different sources (for sulfur, sulfide sodium and sodium sulfate), three kinds of diet, digestion and metabolism test and determination of chyme liquidity to explore different inorganic sulfur and nitrogen and sulfur deposition of sulfur circulation. The results show that: the consumption of sodium sulfate group of nitrogen deposition and both groups were significantly higher than those of sulfur and sodium sulfide group (P <0.05), but each group N digestibility not significantly different (P> 0. 05). Sodium sulfate and sodium sulfide Group Group sulfur deposition, as well as the apparent digestibility were significantly higher than that of sulfur group (P <0.05). Kraft absorption in the rumen and mainly absorbed in the intestine; sulfide in the rumen and can
