Effects of milk from animals fed locoweed on kittens, calves, and lambs.

Calves, lambs, and kittens given milk from cows fed locoweeds developed microscopic lesions typical of locoweed poisoning. Serum aspartate aminotransferase activities increased markedly during the feeding period in both the cows given the locoweed and the animals receiving their milk. The results of this experiment indicate that the toxin in locoweed can be secreted in the milk.
