Pesticides in Animal Feeds, Effects of Feeding Dieldrin- and Heptachlor-Treated Alfalfa Hay to Dairy Cows

“…A 40-acre field of first crop alfalfa was divided into 20 plots (1.6 acres each), which were separated from each other bybuffer strips 33 feet wide in one direction and 50 feet wide transversely. The five treatments were as follows: (1) no treatment; (2) 1 ounce of dieldrin per acre; (3) 4 ounces of dieldrin per acre; (4) 1 ounce of heptachlor per acre; and (5) 4 ounces of heptachlor per acre. The five treatments were distributed at random within each field replication.…”

“…THE AMOUNT AND DISTRIBUTION of chlorinated insecticides in the tissues and organs of the animal body have been studied in an attempt to determine their harmful effects. The majority of these studies have been concerned with 1 Present address, Hanford Atomic Energy Project, Richland, Wash. histological observations and accumulation rates (7, 3, 6, 7 7, 12). The reports indicate that other ways of studying the effects of the insecticides on animal tissues might supplement histological and accumulation data.…”

Toxaphene (Camphethlor). A Special Report

“…In a study of toxaphene storage in animals, Bateman et al (1953) found that sheep and steers fed 10 ppm daily in the diet showed no accumulation in the fat after 30 days exposure. However, with repeated dosage, storage in the fat of these animals and also dairy cows was reported by Conley (1952) and Diephuis and Dunn (1949).…”
