Five lots of pigs were self-fed free-choice in dry-lot. All lots received
a mixed animal and plant protein supplement of 4 parts tankage, 4 parts
soybean meal, 1 part linseed meal, and 1 part alfalfa meal. The open-pollinated
sorghum was the Plainsman variety, of excellent quality, -being
especially high in protein. The hybrid sorghum was Farmer's Union
222 and was somewhat high in moisture.
