feet in diameter and 3 feet high in the center. It is evident that such a quantity of herbage can be gathered by a cow in 8 hours only when the sward is dense and at a height that permits rapid collection. Observations made of grazing cattle indicate that a height of about 4 inches closely approaches the ideal.
Since cattle spend as much time in grazing during the night as during the day, equally good pasture should be provided for each period. As an aid to good grazing management, the pasture area should be divided into from three to eight enclosures, each with independent access to drinking water. These enclosures should be grazed alternately. The cost of fencing may be reduced to a minimum by the use of a safe type of electric fence.
FIGURE 28. SELECTIVE GRAZING
Cattle refuse to graze luxuriant herbage growing where droppings
have fallen, but they will eat the herbage If it Is handed to
them or placed on the ground a short distance from the place on
which it grew. The odor associated with the droppings appears to
be the cause for this. Horses will graze much of the herbage left
by the cattle under a system of alternate grazing
