Abstract:

为探究饲粮添加纳米氧化锌对瘤胃发酵的影响,本试验通过体外发酵法研究了纳米氧化锌不同添加水平(0、50、100、200、400mg/kg,干物质基础)对瘤胃培养液pH、氨态氮(NH3-N)、微生物蛋白(MCP)、挥发性脂肪酸(VFA)以及底物有机物发酵率(FOM)的影响。研究结果发现,在体外培养条件下,纳米氧化锌的添加对培养液pH无显著影响(P>0.05);与对照组相比,添加100和200mg/kgDM的纳米氧化锌在6和12h显著提高了FOM和MCP及VFA浓度(P<0.05),降低了NH3-N浓度和乙酸/丙酸的比例(P<0.05)。上述结果表明,纳米氧化锌的添加在体外培养前期(6~12h)能够有效地促进瘤胃微生物对饲粮有机物的发酵,增加MCP产量,提高瘤胃发酵的能量利用效率。
