Effects of dietary endrin on reproduction of mallard ducks (Anas platyrhynchos)

In mallard ducks, dietary endrin (0.5, 3.0 ppm) had no effect on egg production, fertility, hatchability, or hatching survival to 14 days, although a 9.6 per cent decrease in embryo survival was observed at the 3.0 ppm treatment level. At the end of the 12-week oviposition period, the body weight of...

Description
Summary:In mallard ducks, dietary endrin (0.5, 3.0 ppm) had no effect on egg production, fertility, hatchability, or hatching survival to 14 days, although a 9.6 per cent decrease in embryo survival was observed at the 3.0 ppm treatment level. At the end of the 12-week oviposition period, the body weight of male ducks receiving 3.0 ppm endrin was 4.5 per cent lower than that of controls. Percent body fat in males decreased with increasing endrin concentrations, whereas the reverse was true in females. Endrin residues in body fat were approximately 6 times higher (ppm basis) than the respective dietary concentration, with females accumulating higher levels than males. Eggs from females in the 0.5 and 3.0 ppm endrin treatment groups contained 0.43 and 2.75 ppm endrin respectively.
