inclusion level- уровень включения??*

[en_route]

как будет правильно перевести "inclusion level" в след. контексте:

Because of its glucosinolate content, the use of rapeseed meal is often associated with a reduction in growth rate and poor palatability of feed. If the level of inclusion is higher than 5% in layer feed, a fishy taint or off flavor in the yolk of eggs from heavy strain brown egg layers will occur....
...Above the 10% inclusion level, hemorrhagic fatty liver is often observed with associated higher levels of mortality.

меня смущает "уровень включения", может кто знает?....

пасиб заранее!
