Abstract

A feeding experiment with dairy cows was conducted in an attempt to define a level of DDT in feeds that would be un-detectable in the milk. For six weeks pairs of animals—including producers of both high- and low-fat milks—were fed daily rations containing 0-5 ppm—parts per million—of DDT, based on their feed intake.
