The objects of this experiment were to determine the comparative value and efficiency of meat meal tankage, dried buttermilk and various combinations of these feeds on health, gains, feed requirements, water consumption, time required to reach 225 pounds average weight and other factors, when these protein feeds were self-fed along with shelled corn to growing and fattening pigs in dry lots.

The pigs used in this test were very uniform in age, weight and breeding. They were all sired by the same purebred Hampshire boar and were out of either related purebred or very high grade Hampshire sows. The pigs were selected from four litters.
