Experimental procedure has already been outlined [see preceding 2 abstr.]. In this study, the supplement contained 60% soya bean meal and 40% tallow. 28 cows were used. Compared with the unsupplemented control diet, milk fat yield was increased by 17, 23 and 5% on the low, medium and high levels of supplement resp., and there was a decrease in proportion of C4-C16 and an increase in C18:0 and C18:1 fatty acids in the milk fat.
