A.S. Series 64-26
This trial was conducted at the Eureka Station which is an area of the state where barley is relatively more easily available as a swine feed than corn. Barley has been shown to have about 90 percent of the feeding value of corn when properly supplemented. Barley has higher protein content than corn but also has a higher fiber content. One means which has been used to make this otherwise excellent feed more useful is to pellet complete ground mixed barley rations. Results have been variable with respect to improve d pig gains and feed efficiency when bar ley rations were fed in both meal and pelleted form. Pasture-raised spring pigs which are provided with only minimum shelter and have access to feed and water free-choice usually appear to be uncomfortable on warm days. Eating and drinking is usually limited to the night or cooler periods of the daytime. It is known that excessive heat reduces feed consumption which in turn reduces gains. Shade over feeders and waterers might be a means of permitting pigs to eat any time during the day. Swine production facilities at the Eureka Station limit the production to pasture conditions which are typical of those found on many farms. The objectives of this trial were to: (1) Compare performance of pigs fed a complete ground mixed barley ration in both meal and pelleted form, (2) compare performance of pigs with and without shade for the feeder and waterer, and (3) determine, if any, the joint effects of these treatments.
