Effects of Aldrin on Young Pen-Reared Pheasants

Three levels of encapsulated aldrin (.05, 1.0, and 1.5 mg) were administered weekly to young pen-reared pheasants from 5 to 11 weeks of age to determine effects on growth and residue levels in brain, feathers, and whole body during and after treatment. During treatment, birds were weighed weekly. After treatment ceased, birds were weighed every other week until 21 weeks of ---. Analysis of residues was by electron capture gas chromatography. Growth of pheasants --- 5 to 21 weeks of age was depressed (P 0.01) by administration of aldrin dosages of 1.0 to 1.5 mg. Aldrin values in the brain and whole body of birds sampled throughout the experiment varied little (0.02 ppm to 0.08 ppm) regardless of treatment level while dieldrin values increased proportionally with treatment levels during the period of administration. Then weeks after treatment was terminated brain and whole body levels of dieldrin from birds surviving the experiment were comparable to controls. Administration of 1.5 mg. of aldrin in a single dosage caused death of 11 of 22 five-week old pheasants within 48 hours. Aldrin plus dieldrin levels in these 11 birds were: brain, 2.29 ppm to 4.25 ppm and 2.72 ppm average; whole body, 1.45 ppm to 4.35 ppm and 2.38 ppm averages; feathers, o.50 ppm to 1.43 ppm and 0.81 ppm average.
