Dairy Farming

Morrison says, "Among all the animals of the farm, dairy cows of good productive capacity are unequaled as producers of human food." The cow produces more human food from a given quantity of feed than is produced by any other farm animal. As producers of protein, hens are the nearest competitors of dairy cows, while as producers of energy the pig ranks second. However, both the hen and the hog require more concentrated food in proportion to the roughage or hay than the cow, and in this way, except as consumers of waste products, they are hardly as efficient.
