摘　　要：本试验旨在运用粗饲料分级指数（GI）和饲料相对值（RFV）评定黑龙江省反刍动物常用粗饲料的营养价值,并就粗饲料的GI和RFV进行比较研究.结果表明：对羊（标准体重为40 kg）而言,苜蓿的GIN和GIA为2.66～4.00 MJ/d和4.02～5.51 MJ/d,玉米青贮为0.82～0.98 MJ/d和1.34～1.64 MJ/d,羊草为0.47～0.67 MJ/d和0.86 ～1.17 MJ/d,玉米秸秆为0.24～0.31 MJ/d和0.49 ～0.54 MJ/d;对奶牛（标准体重为600 kg）而言,苜蓿的GI为18.47～26.00 MJ/d,玉米青贮为8.65～11.30 MJ/d,羊草为3.36～5.06 MJ/d,玉米秸秆为3.34～4.10 MJ/d;4类粗饲料中,苜蓿的RFV为1 04.50～112.82,玉米青贮为92.84～109.54,羊草为66.35～75.11,玉米秸秆为74.13～78.31.同类不同地区粗饲料的品质根据GI由高到低排序为,齐齐哈尔苜蓿＞8511农场苜蓿＞肇东苜蓿;肇东玉米青贮＞尖山玉米青贮＞齐齐哈尔玉米青贮;齐齐哈尔羊草＞肇东羊草＞尖山羊草;对羊而言,8510农场玉米秸秆＞8511农场玉米秸秆＞宁安玉米秸秆;对奶牛而言,8510农场玉米秸秆＞宁安玉米秸秆＞8511农场玉米秸秆.This study was designed to use Grading Index （GI） and Relative Feed Value （RFV） to assess the nutritional value of common ruminant forage in Heilongjiang province.And compared the GI and RFV of forage.The result showed that for sheep （standard weight of 40 kg）,the alfalfa＇s GIN and GIA were 2.66～4.00 MJ/d and 4.02～5.51 M J/d,the corn silage＇s GIN and GIA were 0.82～0.98 MJ/d and 1.34～1.64 MJ/d,the Chinese wildrye＇s GIN and GIA were 0.47～0.67 MJ/d and 0.86 ～1.17 MJ/d,the corn stalk＇s GIN and GIA were 0.24～0.31 MJ/d and 0.49 ～0.54 MJ/d; For dairy cattle （standard weight of 600 kg）,the alfalfa＇ s GI was 18.47～26.00 MJ/d,the corn silage＇ s GI is 8.65～11.30 MJ/d,the Chinese wildrye＇s GI was 3.36～5.06 MJ/d,the corn stalk＇ s GI was 3.34～4.10 MJ/d; In the four species of forage,the alfalfa＇s RFV was 104.50～112.82,the corn silage＇s RFV was 92.84～109.54,the Chinese wildrye＇s RFV was 66.35～75.11,the corn stalk＇ s RFV was 4.13～78.31.According GI the order from high to low of forage which is from different regions of the same species forage was Qiqihaer alfalfa〉8511 farm alfalfa〉Zhaodong alfalfa; Zhaodong corn silage 〉Jianshan corn silage 〉Qiqihaer corn silage; Qiqihaer Chinese wildrye 〉Zhaodong Chinese wildrye〉Jianshan Chinese wildrye; for sheep,8510 farm corn stalk〉8511 farm corn stalk〉Ning＇ an corn stalk; for dairy cattle,8510 farm dairy cattle〉Ning＇an dairy cattle〉8511 farm dairy cattle.
