摘　　要：利用五个小型试验槽制作深层生物垫床(Deep litter system),研究了四种不同垫料(稻壳、锯末、花生壳、泥炭)按不同比例组合后垫床的综合特性,为深层生物垫床运用于肉牛饲养提供试验依据。结果表明,不同比例的四种垫料对垫床的温度、pH、霉菌和碳氮比都有不同程度的影响。添加泥炭比例过高(37.5%以上)会减小垫床孔隙度,造成了霉菌的大量繁殖,对动物和人造成潜在威胁;但泥炭又从一定程度上控制了氨的排放,因此,泥炭比例应在25%左右。从各组垫床的综合效果来看,第3组(各垫料等百分比)垫料适合制作肉牛用垫床。This study focused on comprehensive characteristics in five bench scale beds with four different bedding materials（rice hull,saw dust,peanut hull,peat）,so that we can learn practical experiences for beef cattle raising on large scale bed.The results indicated that different proportions in bedding materials affected temperatures,pH,mold counts and C/N ratio.High proportion of peat（above 37.5%） decreased the porosity,and increased the mold counts,which had a potential danger for animal and human;however,peat inhibited the emission of ammonia.The optimum proportion of peat was about 25%.For the comprehensive effects of five beds,we suggest group 3（with equal proportion of materials） to be a appropriate bedding system for beef cattle.
