  • Patent number: 5091195
    Abstract: A feed for hens which serves to reduce the cholesterol content of eggs laid by the hens, the feed being made up of laying mash and dehydrated cabbage in a ratio of about three parts of laying mash to two parts of cabbage by weight. The cabbage has been dehydrated by a process which does not raise its temperature to the point where enzymes therein are inactivated. It is believed that the enzymes in the dehydrated cabbage serve to induce cytochrome P-450 in the hen to break down the cholesterol in the body of the hen and, so, reduce the amount going into the eggs.
