摘要:
为评价不同饲用燕麦营养品质及瘤胃降解特性,本试验选取了在青海省海南藏族自治州贵南县种植的17个燕麦品种,于乳熟期收获,测定其常规营养成分、体外发酵参数和体外产气量,计算饲草品质评定指数,利用主成分分析和隶属函数对不同品种燕麦的营养品质进行综合评价。结果表明:各品种燕麦干物质含量为24.44%~32.91% FW,莫妮卡最高;粗脂肪含量为1.60%~4.03%DM,青海444最高;粗蛋白含量为4.35%~6.23%DM,青海444最高;粗灰分含量为4.58%~6.51%DM,青海444最高;可溶性糖含量为3.49%~12.61%DM,青甜2号最高;中性洗涤纤维含量和酸性洗涤纤维的含量分别为45.56%~62.31%DM和23.75%~32.38%DM,均为坝燕6号最高。饲草品质评定指数方面,相对饲喂价值和相对饲草品质分别是95.06~143.74和118.32~213.25,均为甜燕1号最高。饲草分级指数为6.34~11.91 MJ·d-1,青海444最高。瘤胃发酵参数方面,pH为6.58~7.07,悍马最高;氨态氮含量为9.65~15.87 mg·dL-1,青海444最高;干物质降解率为63.01%~76.47%,牧王最高。体外产气量方面,不同品种燕麦不同时间点的累计产气量存在差异。72 h累计产气量为56.59~105.28 mL,产气最多的为牧王。综合以上结果,进行主成分分析和隶属函数综合评价,17个燕麦品种的综合得分排序如下:青海444>甜燕1号>青甜1号>甜燕3号>青甜2号>甜燕麦>贝勒>莫妮卡>牧王>白燕7号>悍马>优牧1号>梦龙>福瑞至>太阳神>爱沃126>坝燕6号。因此,青海444是适合在高寒地区种植的营养品质及潜在饲用价值最优的燕麦品种。
