Abstract
Extract
The present trtal was designed to find the effects of feeding chickens low levels of lindane from hatching for the relatively short period of one month. A case involving 100 per cent, mortality of chickens and turkey poults within three weeksof hatching was reported to this laboratory. The birds had been fed mash reputedly contaminated with 4 parts per million (p.p.m.) of lindane. No published data were found on the toxicity of lindane to young birds, although studies with this insecticide on mature birds have been made. Ware and Naber (Citation1961) fed laying hens for 60 days on diets containing up to 10 p.p.m. of lindane with no effect on health and egg production. Teh-Neng and Chung-Jen Citation(1956) fed laying hens for three months on lindane at levels of 2, 4, and 10 p.p.m. with no toxic symptoms or histological changes in viscera. Black et al. Citation(1950) reported no ill-effects in poultry from continuous ingestion of up to 84 p.p.m. benzenehexachloride in the food. Ivey et al. Citation(1961) determined lindane residues in fowls and eggs, and Ware Citation(1961) benzenehexachloride residues in eggs following the spraying of poultry house litter with these insecticides.
