摘要： 选用9只体况良好，体重25~30 kg的2周岁内蒙古白绒山羊半同胞羯羊，安装永久性十二指肠近端瘘管和两侧颈静脉血插管进行试验，试验采用随机区组试验设计，3个试验处理为在基础日粮条件下的3种十二指肠氨基酸灌注模式，分别为M、M90+C10和M80+C20。本试验采用稳定性同位素d₅-Phe大剂量一次灌注法，测定不同组织的蛋白质合成率（FSR）。结果表明，小肠可吸收氨基酸模式对皮肤蛋白质的FSR有显著影响。其中，M90+C10组和M80+C20组皮肤蛋白质的FSR极显著高于M组（P<0.01）。小肠可吸收氨基酸模式对空肠、肝脏和肌肉组织的FSR无显著影响（P>0.05）。同时表明小肠可吸收氨基酸模式对氨基酸在外周组织，尤其是皮肤和肌肉组织间的分配具有显著影响（P＜0.05）。

Abstract: Nine wethers of Inner Mongolian White Cashmere (IMWC) goats (25-30 kg) with the same father, fitted with permanent cannulas at the proximal duodenum, and with two sides temporary carotid venous catheters were used to investigate the effect of absorbable amino acid pattern in the small intestine, i.e. M, M90+C10 and M80+C20, on FSR of proteins in the jejunum, liver, muscle and skin tissues in IMWC goats. The results showed that absorbable amino acid pattern had significant effect on protein FSR in skin tissue, and M90+C10 and M80+C20 were significantly greater than M (P<0.01). There were no significant effect of amino acid pattern on the FSR in jejunum, liver and muscle (P>0.05). It also was showed that absorbable amino acid pattern had significant effect on distribution of amino acids between skin and muscle(P＜0.05).
