title: Effect of toxaphene on the performance of White Leghorn layers and their progeny.
abstract: An experiment involving 48 white leghorn layers fed 0, 10 and 100 p.p.m. of toxaphene has been conducted. Except for a slight decrease in egg production, no adverse effects on various performance parameters including fertility, hatchability and survival of progeny were observed. A significant increase (P less than .05) in average 7-day weights of progeny was noted.
