摘要
本文用１５ 个精、粗饲料日粮配合比例组合进行饲喂奶牛试验，并根据最小成本原理对试验所得数据进行了分析，结果表明：在日产奶量２０ ｋｇ 左右时，每天／ 头喂给５ ．８ ｋｇ 混合精料（ 干物质） 和９ ．６ ｋｇ 粗饲料，即精粗料比为３８ ：６２ 时成本最低。
rations of mixed cocentrate and forage feed on milk production of dairy cow were conducted in the feeding experiments.Trial figures were computed by smallest cost principle.The result indicated that cost of feeding 5.8 kg/d mixed cocentrate and 9.6 kg/d forage feed were lowest in the 20 kg/d milk production.
