The main toxic compound
in the rapeseed meal is Gls. Glucosinolates and
its degradation products impair palatability, affect liver
and kidney functions, and interfere with iodine availability
[3]. The feed ratio of rapeseed meal as protein source
remains at lower percentages than that of soybean meal
since, most likely, its high content of other anti-nutritional
components, such as phenols, phytate and fiber, as well as
its lower lysine bioavailability [4]. Moreover, rapeseed proteins
are not easily digested compared to other protein
rich materials such as fishmeal or soybean meal rendering
them less valuable [5].
