Effects of DDT, Toxaphene, and Dieldrin on Pheasant Reproduction

Effect of Dieldrin and Calcium on the Performance of Adult Japanese Quail (Coturnix coturnix japonica)

“…Several investigators have noted that egg production was affected when dieldrin was administered in the feed to pheasants, Bobwhite quail and Japanese quail (Genelly and Rudd, 1956b;DeWitt, 1955;Walker et al, 1969). Feed consumption data showed all groups consumed between 19 and 22 g. per hen per day, regardless of the dieldrin or calcium level employed.…”

“…Egg production decreased with dieldrin contamination (Genelly and Rudd, 1956b;Walker et al, 1969;Baxter etal., 1969;Atkins and Linder, 1967;Linder and Lamb, 1967). Others have noted no effect (DeWitt, 1955;Graves et al, 1969).…”

“…were administered for periods up to 18 weeks. Genelly and Rudd (1956b) working with pheasants noted that the first two weeks after hatch were perhaps the most critical in chick survival. and above.…”

Reproduction in a Population of Herring Gulls (Larus argentatus) Contaminated by DDT

“…Pheasants fed a diet of 90 ppm approximately dry weight for 3 months laid two eggs that averaged 162 ppm of DDT plus metabolites, wet or dry weight not specified (Genelly & Rudd 1956). Pheasants fed a diet of 90 ppm approximately dry weight for 3 months laid two eggs that averaged 162 ppm of DDT plus metabolites, wet or dry weight not specified (Genelly & Rudd 1956).…”

Toxaphene (Camphethlor). A Special Report

“…In other reproduction studies, also adverse effects on the offspring were always related to maternal toxicity (USDA, 1977). In pheasants, egg-laying and hatchability were significantly depressed at 300ppm toxaphene in the diet; already at 100 ppm, the mortality of the young pheasants was significantly greater than that of controls (Genelly and Rudd, 1956).…”
