Effect of dietary pyrimethamine on hatchability and a recommendation on a procedure to check teratogenicity by hatchability.

open access: yesJapanese poultry science, 1987
Teratogenic effect of pyrimethamine at dietary levels of 0, 5, 10, and 20ppm was examined. Fertile eggs obtained by feeding the experimental diets to laying White Leghorn hens, were set in an incubator. Fertility, early and late mortality of the embryos, hatchability and incidence of the deformed chicks were tested. Pyrimethamine up to 20ppm had little
