The inclusion of 10% of a high glucosinolate Brassica napus meal in the diet of three popular broiler strains for 3 weeks or 6 weeks from 1‐day‐old did not affect the flavour of the meat or exacerbate liver haemorrhage. In one strain the activity of hepatic trimethylamine oxidase fell by 50% but did not reach the levels present in hens laying tainted eggs. The body weight was reduced by about 7‐11% and the relative weight of the liver was increased by about 9‐14%.
