Responses of growing chickens to high dietary contents of rapeseed meal

The feeding of diets high in rapeseed meal to broiler chicks caused enlargement of the liver and may have caused some mortality. 2. High‐glucosinolate Brassica napus rapeseed meal caused a higher incidence of haemorrhagic livers among broiler chicks than did B. campestris meal and a low‐glucosinoate B. napus meal was without effect. 3. White Leghorn cockerels were of little use in studying the aetiology of haemorrhagic liver after feeding rapeseed meal if mortality was used as a criterion. They may be of value in studies of liver function.
