【摘要】 选用新扬州鸡成年公鸡，应用排空强饲法研究了对不同单宁含量高粱营养价值的影响。结果表明，高粱单宁含量高，对其营养物质利用影响很大，低单宁（０．０５８５％）的ｋｓ－３０４杂交高粱和高单宁（１．３４２５％）的褐高粱中干物质利用率、表观代谢能、真代谢能、总氨基酸及各种氨基酸的表观消化率均存在极显著差异（Ｐ＜０．０１），特别是氨基酸的消化率，低单宁的杂交高粱总氨基酸及各种氨基酸的真消化率为６３．０３％～９５．３４％，而高单宁的褐高粱仅为－８．３８％～２７．９６％。更多还原

【Abstract】 New Yangzhou roosters were used to investigate the effect of tannin contents on nutritive value in sorghum The results showed: utilization of nutrients were affected greatly by high level tannin There were significant differences ( P <0 01) in utilization of dry matter (DM); apparent metabolizable energy (TAA), true metabolizable energy (TME); apparent digestibility (AD) and true digestibility (TD) of total amino acid (TAA) and all kinds of amino acid (AA) between ks 304 crossing sorghum (low tannin, 0 0585%) and Brown Sorghum (high tannin, 1 3425%), especially in the digestibility of AA The true digestibility of TAA and each AA in low tannin crossing sorghum and high tannin Brown sorghum were 63 03%￣95 34% and -8 38%￣27 96%, respectively更多还原
