The effect of pre-dosing Homeria pallida Bak. to cattle to prevent tulp poisoning.
Newly weaned calves with no previous exposure to Homeria pallida were dosed with H. pallida material prepared as a broth, a suspension of charred leaves of leaves chopped into small shreds. Three hours later they were put into a camp where H. pallida constituted 50% of the grazing. Equal numbers of animals in each of the treated groups and in the untreated group subsequently developed H. pallida poisoning. By about the 4th day, both the treated and untreated animals appeared to have adapted to H. pallida and to avoid it while grazing.
