The effect of feeding an odd‐numbered carbon triglyceride, triundecanoin, upon lactation in the cow was studied. This fat appeared to be subject to considerable degradation in the rumen. There was no indication, however, that it yielded any increase in relative propionate concentration. A large amount of the odd‐numbered carbon triglyceride was rejected by the animals, with a general decrease in feed consumption and consequent reduced milk yield. Fat production was unchanged. Some undecanoate passed into the milk but only at a low rate. There was a large difference in animal response. Feeding triundecanoin protected from rumen degradation led to a much greater transfer of undecanoate to the milk, prevented a significant decline in feed consumption and milk yield, but did not affect the milk composition appreciably. Smaller increases were observed in the amounts of other odd‐numbered carbon fatty acids in the milk.
