摘要 为探明回 直肠吻合荷术猪日粮中补加可溶性糖的得失利弊 ,本文采用 4头术后 14周的回 直肠吻合猪 ,研究了在日粮中补加可溶性糖对养分消化率测值的影响。结果为 :( 1)在试验日粮中添加可溶性糖对干物质的表观消化率有提高的趋势 ,但本试验条件差异不显著 (P >0 0 5) ;( 2 )日粮中添加可溶性糖对氮的消化率和代谢率没有影响 (P >0 0 5) ;( 3)在日粮中添加可溶性糖对氨基酸的表观消化率测值没有影响 (P >0 0 5)。本研究表明在回 直肠吻合猪日粮中添加 10 %的可溶性糖不仅可以在一定程度上弥补回 直肠吻合荷术猪在能量代谢上的亏损 ,而且对氨基酸消化率的测值没有影响。 Four 14 week aged post sugery ileo rectal anastomosis pigs were used to explore the effects of supplementing soluble sugar (100 g corn starch +sucrose(1∶1)/kg diet) on the digestibility of dietary nutrients.The results indicated that supplementing soluble sugar didn’t affect the digestibility of dry matter,the digestibility and metabilizability of nitrogen,the apparent digestibility of all amino acids(P>0.05).
