I've looked in my animal nutrition book, and I can't find anything on the green stalk bits, only about rapeseed meal its self. If yours is the high glucosinolate variety then the cons seem to out way the pros, but if its the low variety then even though its not really recommened for just weaned pigs and sows. Boars, growers and finishers seem ok
to have it though. There is a paragraph which says: " some authorities, consider rapeseed meals should not be used in starter or sow diets and that level in growers and finisher diets should not exceed 50 and 100 kg/ton respectively." taken from Animal nutrition P McDonald, RA Edwards etc. Its also a source of protein just to say.
