Animal feeding study demonstrates solvent extraction removes trimethylamine-inducing taint factors in brown-egg laying hens, suggesting viable methods to improve feed safety.
Certain rapeseed meals in the diet of hens laying brown eggs result in the production, from some birds, of eggs which have a “ fishy ” or “ crabby ” odour because of the presence of trimethylamine. 2. Such susceptible birds have been used to demonstrate that the activity can be extracted from rapeseed meal with appropriate solvents.
