Abstract
Chicks were able to tolerate large dietary doses of the herbicides 2,4-dichlorophenoxyacetic acid (2,4-D) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), the only adverse effects being a reduction in food consumption and growth rate. A level of 5000 mg 2,4,5-T/kg proved fatal to chicks; a similar level of 2,4-D, while not resulting in death, did cause histological changes. Chicks were able to tolerate this level of either herbicides for up to 1 wk, however, and resume a normal growth rate when returned to uncontaminated food. No specific effect of high dietary levels of these herbicides was noted on plasma calcium or magnesium concentrations. The birds were able to discriminate between contaminated and uncontaminated food; when given a choice they rejected contaminated food and grew at a normal rate.
