Tropical Legumes in Animal Nutrition Book

I started reading the book five times before I finally decided to just sit down and finish it in one setting. The field of animal driving themselves is obviously new and facing obstacles in finding funding and locating clear evidences, as the author clearly acknowledged. However, as a scientist, it is appalling to see a book throwing out folk stories as scientific evidence without citing many known collaborators. There are also formatting errors in the book. It's a good introduction to a new vote to this major drug problem our culture imposes on us, but I would really like to see more than anecdotes in a book.
