Summary
Previous research at the Southeast South Dakota Experiment Farm has shown that the main economical advantage of controlled environment housing for swine is an improved feed efficiency during the winter months. Some research workers have reported that gilts require a ration of higher protein content than do barrows. If this observation is true, barrows and gilts should be fed separately for maximum performance and efficiency. The purpose of the experiment reported herein was to study the performance of barrows and gilts fed separately rations containing either 17 or 15% protein to about 110 lb. and 14 or 12% protein from 110 lb. to market when housed in a controlled environment building or an open front building with feeders and waterers outside.
