We've never fed canola bales, but have fed canola silage. In 2002 we were very dry in the spring and the canola did not germinate. It did germinate in late July when the rain finally came. Our neighbors had so much late germinating canola that they gave it to us for free if we got if off their fields. It saved them the cost of spraying it. We silaged a lot of canola in September. We found that the calves took a little longer getting on to it than cereal silage, but once they got going they liked it and did just as good as cereal silage.
