We examined the effect of intake of total mixed ration (TMR) containing dried soybean curd residue on conjugated linoleic acid (CLA) content in milk fat. Holstein cows (n=6) were randomly divided into either a control group or a subject group. Cows in the control group received diets containing 45% forage and 55% grain on a dry matter basis. In the subject group, the grain was partly replaced with dried soybean residue, which comprised 13.7% of the total diet. The experimental diets were fed for 12 weeks. Fatty acid profiles of fat in feed and also milk were obtained by way of gas chromatograph analyses. It was observed that the cows fed with TMR containing dried soybean curd residue produced milk with higher CLA content during the initial period.
