Coffe y 2At times stale bread may be available as a feed ingre-A comparison of the value of bread versus corn (/lb), dient for swine. When cheap enough, bread is an effectivebased on the price of corn for a range of corn prices, is substitute for grains in the ration. The composition ofgiven in Table 2. white enriched bread is shown in Table 1. On a weight-for-weight basis, the water content of bread (36%) is 3 times that of corn (10%). We should realize that water in feed ingredients is of no greater value to the animal than water from any other source. Compared to corn, the extra water in bread dilutes concentration of energy and other nutrients. Here are some guidelines for utilizing bread in swine feeding: 1)Bread is approximately 75 to 80% as valuable as corn for swine feeding. Therefore, if bread can be purchased for 75 to 80% of the price of corn, it may be economical. 2)Feeding bread may cause constipation due to its low fiber content (<1%). This is particularly a problem in confinement operations where pigs do not have access to other sources of fiber. 3)Higher moisture coupled with lower fat content makes bread less valuable for swine feeding than certain other bakery wastes (such as doughnuts or cake) due to lower concentration of energy in bread. 4)Rations that contain bread should be adequately fortified by vitamin and mineral supplementation in a manner similar to supplementation of rations that contain grains.Table 1.

This does not account for increased handlin g costs associated with the use of bread; e. g ., factors such as removal of bread from wrappers and disposal of these wrappers.
