Hi Ghislain and all

Heather Matilla did work on feeding pollen and substitutes while at U  
of Guelph.  We had her speak, to the joint meeting of the Wellington  
and Dufferin Beekeeping groups, about her work.  She is now in the US  
and no doubt has continued her work on pollen needs of honeybees.   
Peter can likely find more info.
