To investigate the feeding value of the concentrated feedstuff including the Korean ginseng meal instead of wheat bran, Holstein milk cows were fed by this feedstuff (10kg/day) for 80 days, and the amounts of milk production and quality of milk were checked. The results are as follows: 1. Milk production of cows fed by the concentrated feedstuff including the ginseng meal was increased as averaged as 1.25kg/day compared with those of controlled cows during same period(SA) and before feeding treatment (SB). Significant different of milk production was found between cows treated and cows of SB plot, but there was no significant difference of milk production between cows treated and cows of SA plot. 2. Milk fat content was significantly increased as moth as 0.22%, 0.69% and 0.455% by the feeding of ginseng meal compared with that of SB Plat and that of SA Plot, and as average value, respectively. 3. Solid not fat (SNF) of milk from cows fed by the ginseng meal was also significantly increased as much as 0.845%, 1.339% and 1.0925 tempered with these of cows before treatment (SB) and cows controlled (SA), and as average value, respectively. 4. Specific gravity of milk produced from cows treated was higher as average as 0.0055 than those of controlled plots (SA and SB). Significant difference of specific gravity was found between cows treated and cows of SA plot, but there was no significant difference between tows treated and cods of SB plot. 5. Acidity of milk produced from cows treated was lower as averaged as 0.0045 than those of controlled plots (SA and SB). Significant difference between cows treated and cows of SA plot was found, but there was no significant difference between cows treated and cows treated and cows of SB plot.
