通过本研究得出：1，脂肪酸钙、植物脂肪粉以及硬脂肪对瘤胃PH、氨浓度、乙丙酸产量、干物质采食量、营养物质瘤胃降解率、血钙、TCH、TG等方面影响并不显著，但硬脂肪对丁酸以及乙丙酸摩尔比有显著影响(P.05)，植物脂肪粉对血镁浓度也有显著影响(P.05)2，过瘤胃脂肪对营养物质全消化道消化率影响较大，其中脂肪酸钙组与植物脂肪粉显著降低了蛋白消化率，植物脂肪粉能显著降低ADF和NDF消化率(P.05)，但处理组之间差异不显著。

Results The main biochemic al items such as pH,osmole,electrode slope and linear scope between our develope d internal standard A and the primary internal standard A in NOVA 16 analyzer re agent pack were in good accordance.

结果：自配内标准A液与原装内标准A液的主要理化指标：pH 、渗透压、电极斜率、线性范围均一致，自配内标准A液的精密度与原装内标准A液所测结果之间的相关性(r＝0.950～1.000)及自配A液的批内(P＞0.05)、批间(P＞0 。05)稳定性较好，长期使用对电极无损害。
