为筛选适宜南方农区推广的非常规饲料资源,采用体外产气法测定从南京周边搜集到的32种非常规饲料2 h、4 h、6 h、8 h、10 h、12 h、17 h、24 h、48 h累积产气量( GP)、发酵参数( A、b、LAG)、干物质体外消化率( IVD-MD)和纤维体外消化率( IVNDFD、IVADFD),评定其对反刍动物的营养价值。结果表明：理论最大产气量大于200 ml的非常规饲料由高到低依次为大豆皮、玉米苞叶、喷浆玉米皮、桔子皮、蚕豆荚、苹果渣、高粱壳、米糠粕、京甜紫花糯2号秸秆,其中大豆皮、桔子皮、苹果渣、高粱壳的产气延滞时间较长(大于3 h),桔子皮、苹果渣产气速率较低(小于10 ml/h),IVDMD最高为大豆皮(85.41%),最低为京甜紫花糯2号秸秆(56.85%)；纤维消化率排名前5的依次为大豆皮、喷浆玉米皮、玉米苞叶、桔子皮和大蒜叶,IVNDFD均大于60%,最高为大豆皮(92.42%)；秸秆荚壳的NDF、ADF含量是影响其发酵产气特性的主要因素。米糠粕、大豆皮、喷浆玉米皮、桔子皮、苹果渣、玉米苞叶、蚕豆荚具有较高的营养价值,适合在南方农区推广。

To select unconventional feeds suitable in south China agriculture area, thirty-two unconventional feeds collected from Nanjing and its surrounding areas were evaluted for the nutritive values to ruminants by measuring cumulative gas productions in 2 h, 4 h, 6 h, 8 h, 10 h, 12 h, 17 h, 24 h, 48 h, fermentation parameters and in vitro digestibilities of dry matter ,acid detergent fiber and neutral detergent fiber. There were nine feeds showing maximum gas productions a-bove 200 ml, which were soybean hull, corn bract, corn bran, orange peel, broad bean pod, apple pomace, sorghum hull, rice bran meal, and corn stalk, from the highest th the lowest. Among them, four feeds took longer time to start gas produc-tion, which were soybean hull, orange peel, apple pomace, and sorghum hull and two feeds, orange peel and apple pom-ace, displayed lower gas production speeds. Soybean hull had the highest in vitro dry matter digestibility(85. 41%) and corn stalk had the lowest (56. 85%). The top five feeds with higher fiber digestibility were soybean hull, corn bran, con bract, orange peel and garlic leaves, with neutral detergent fiber digestibility all above 60%. For crop there are seven different kinds feeds including rice bran meal, hull, corn bran, orange peel, apple pomace, corn bract and broad bean pod owning high nutritional values suitable for ruminants in south China agriculture region.
