Query: Rational vs Rotational - This concept could change your farming life forever...

Challenge your thinking and change your ways. Your pastures will thrive, your animals will be healthier and you'll have more time to lay in the hammock instead of throwing hay bales around. Andre Voisin, a French farmer, biologist and chemist--as well as a teacher at the Institute of Veterinary Medicine in Paris, designed a system that he calls "rational grazing" (as opposed to the generic term "rotational grazing"). Rational grazing takes into account the needs of the animal and plant, rather than the animal alone. The term "rational grazing" can mean two things: the thinking way of grazing management, or a system for rationing out the forage. Interested? Then read the book!
