Show grass and hay grass and hay produce such beef and brawn as horses and bullocks possess and yet are unsuitable for humans because the digestive apparatus of the herbivorous animals has become specially adjusted to deal with the coarse fibers of grass and specially enlarged to cope with the great bulk that must be taken daily in order to secure adequate nourishment humans can eat young tender shoots of some kinds of grass without ill effects but the hard stalks that cause no inconvenience to a horse would be as damaging to us as the grit a chicken swallows many grass eating animals like cows and camels have multiple stomachs to help them |
