PGGRC approves the paper - I wonder if yopu need to be a little more clear with the use of RP as your abbreviation for Forage Rape with respect to the % of diet contained in the treatments, I found it a bit confusing.  - I suggest that you reference it as Forage rape percentage (RP %) in the tables and beginning so that its clear what you mean. R could be ryegrass and P could be "pasture"
