摘要

This experiment was carried out to investigate the effects of proportion of concentrates and roughages on growth and carcass traits of Hanwoo steers. Concentrates and roughages were allotted three levels of 35 to 11%, 44 to 12% and 53 to 13%, respectively from the growing period to finishing period. Concentrate and roughage intake of Hanwoo steers were increased progressively until body weight reached 450kg and 300kg, respectively and reached 1.8 to 1.9% and 1.04 to 1.44% to body weight, respectively but thereafter were decreased gradually. Marbling score and beef grade were tended to be increased when steers were fed 44% roughage compared with the steers fed 35% or 53% at the growing period. Therefore, it can be concluded that feeding 44% of roughage is desirable rather than feeding 35% or 53% of roughage when steers are fattening.

本实验旨在研究浓缩物和粗饲料比例对Hanwoo阉牛生长和胴体性状的影响。从生长期到结束期，浓缩物和粗饲料分别分为35％至11％，44％至12％和53％至13％三个等级。 Hanwoo阉牛的浓缩和粗饲料摄入量逐渐增加，直至体重分别达到450kg和300kg，分别达到体重的1.8-1.9％和1.04-1.44％，之后逐渐下降。当饲喂44％粗饲料时，大麻树的评分和牛肉等级往往会增加，而生长期饲喂35％或53％的阉牛。因此，可以得出结论，饲喂44％的粗饲料是理想的，而不是在饲料增肥时饲喂35％或53％的粗饲料。
