<p>18 ANIMAL FEEDER The device disclosed includes an outer cage of bars through which cows may pass their heads and necks, but not their shoulders. The device includes an inner cage, which holds a cylindrical hay-bale. The arrangement is such that the cows must reach through the bars of the outer cage in order to reach the hay in the inner cage. The device includes a trough which extends between the two cages, so that any hay that falls from the cow's mouth while the cow has its head between the bars is caught in the trough. The feeder practically eliminates hay wastage.</p> |
