This study was conducted to investigate the effects of bedding thickness of sawdust on feed intake, blood metabolites concentration and environmental condition of cowshed floor for Hanwoo. Feed intake was increased at thicker bedding groups (15 or 20cm), compared with thinner bedding group (10cm). The thicker bedding had a positive effect on concentration of serum total protein, high density lipoprotein (HDL)-cholesterol, low density lipoprotein (LDL)-cholesterol and γ-glutamyltransferase (GGT). Moisture content and the number of E. Coli in the bedding material were remarkably lower in 15 and 20 cm groups, compared with 10 cm group. Based on the data obtained in this study, approximately 20 cm bedding thickness or at least over 15 cm would be maintained to improve the health condition of Hanwoo and hence to enhance the productivity.
