| 摘 要： | 取来自于３头装有永久性瘤胃瘘管山羊的瘤胃液，在体外厌氧条件下以干草粉（占７５％）和混合精料粉（占２５％）为底物进行培养。在培养液中加入离子载体Ｎ９５，培养液中Ｎ９５质量浓度分别为０．２５、０．５０、１．００、２．５０和５．００ｍｇ·Ｌ－１。试验表明：Ｎ９５对培养液中ＴＶＦＡ（ｔｏｔｌｅｖｏｌａｔｉｌｅｆａｔｙａｃｉｄ）无明显影响，但显著降低了乙酸与丙酸的比例（从２．７０５降到１．５９４）以及培养液中氨氮（ＮＨ３－Ｎ）的质量浓度（从６９．０９下降到６１．０３ｍｇ·Ｌ－１，Ｎ９５使培养液中ＭＣＰ（Ｍｉｃｒｏｂｉａｌｃｒｕｄｅｐｒｏｔｅｉｎ）质量浓度从５５．６９上升到６５．６８ｍｇ·Ｌ－１（Ｐ＜０．０５），而使ＴＤＴＡ（ｔｏｔｌｅｄｅｈｙｄｒｏｇｅｎａｓｅ）质量浓度从３３６．５降至１５０．４μｇ·Ｌ－１（Ｐ＜０．０５）。结果显示了离子载体Ｎ９５改善了瘤胃发酵类型

| Abstract: | Rumen fluid from 3 goats were incubated in anaerobic midia with hay(75%),concentrate(25%)as the substrate for 8 h in vitro.The polyethers ionophore N95 were added to the incubation bottles at concentrations ranging form 25,50,100,250,to 500mg·L -1 .N95 decreased the ratio of acetate to propionate from 2 705 to 1.549 and decreased the NH 3-N from 69.09 to 61.03mg·L -1 (P<0.05),increased MCP(microbial crude protein)production from 55.69 to 65 68mg·L -1 (P<0.05)and decreased the activity of TDHA (total dehydrogenase)from 336.5 to 150.4μg·L -1 (P<0 05).The results suggest that ionophore N95 improves rumen fermentation. |
