Negative effects of ergot alkaloids have been observed in sows fed sorghum grain infected with sorghum ergot (17% C. ![]() Moreover, reduced prolactin secretion and consequently agalactia are major adverse effects in animals.

Consequently, it is practically impossible to determine the exposure to individual toxins.ĭue to the fact that animals are exposed to a multiplicity of alkaloids when consuming endophyte-infected tall fescue, a combined alkaloid effect has been suggested. This mixture results from the fact that the kinds of alkaloids present in grains and their levels can vary widely.
