摘要: 为了对内蒙古巴彦淖尔市绵羊常用粗饲料营养价值和粗饲料质量等级进行科学评价,采用我国反刍动物营养学家卢德勋提出的粗饲料分级指数(GI值)评定指数,对该地区的粗饲料营养成分进行了分析,并对饲草质量进行了评价。结果表明,巴彦淖尔市绵羊粗饲料GI值分级结果为:禾本科牧草中,披碱草3级、燕麦3级、赖草4级、无芒隐子草4级、狗尾草4级、高丹草4级、黑麦草4级、湖南稷子5级、甜高粱5级、戈壁针茅4级、稗草5级、冰草5级、画眉草5级、羊草5级、大麦5级、谷草5级;秸秆饲料中,葵花秸秆5级、葵花盘2级、高粱秆5级、玉米秸秆5级、麦秸5级、玉米芯5级;青贮饲料中,玉米全株青贮5级、葵花秸玉米秸混合青贮5级、番茄渣麦秸混合青贮4级。

Abstract: The present study was designed to scientifically evaluate the nutritional value and quality grade of the commonly used sheep roughage in Bayannur City of Inner Mongolia.Some roughage varieties frequently employed in sheep breeding in this region were chosen as materials to assess their GI value by using the parameters of dry matter intake,energy and crude protein content.The results showed that Elymus dahuricus was 3rdgrade,Avena sativa was 3rdgrade,Leymus secalinus was 4thgrade,Cleistogenes songorica was 4thgrade,Setaria viridis was 4thgrade,sorghum hybrid sudangrass was 4thgrade,Lolium perenne was 4thgrade,Echinochloa frumentacea 5thgrade,sweet sorghum was 5thgrade,Stipa tianschanica var.gobiea was 4thgrade,Echinochloa crusgalli was 5thgrade,Agropyron cristatum was 5thgrade,Eragrostis pilosa was 5thgrade,Leymus chinensis was 5thgrade,Hordeum vulgare was 5thgrade,millet straw was 5thgrade;among the frequently used crop straw,sunflower straw was 5thgrade,sunflower calathide was 2ndgrade,sorghum straw was 5thgrade,corn straw was 5thgrade,wheat straw was 5thgrade,corn cob was 5thgrade;among the frequently used silage,whole plant corn silage was 5thgrade,sunflower straw+corn straw silage was 5thgrade,tomato pomace+wheat straw silage was 4thgrade.
