Mallard egg quality: enhancement by low levels of petroleum and chlorinated hydrocarbons [Anas platyrhynchos]

Four groups of 20 mallard hens each were randomly assigned to receive a diet containing 0.5% South Louisiana crude oil, one containing 5 ppm DDE, one containing 0.5% crude oil and 5 ppm DDE, or a diet of control, untreated food. The study was designed to examine the effects and interactions of pollu...

Description
Summary:Four groups of 20 mallard hens each were randomly assigned to receive a diet containing 0.5% South Louisiana crude oil, one containing 5 ppm DDE, one containing 0.5% crude oil and 5 ppm DDE, or a diet of control, untreated food. The study was designed to examine the effects and interactions of pollutants on egg Quality. Egg fertility did not differ among the groups. The increased mass of eggs laid by hens fed the oil-polluted diet was accompanied by disproportionate changes in the weight of each egg component. Hatchability of these eggs was significantly less than that of eggs laid by hens fed the other diets.
