Abstract
A basal ration containing ground yellow corn, tankage, soybean oil meal, alfalfa meal, and minerals was supplemented with 12 percent or 9 percent of dried molasses, corn, or potato distillers' solubles and fed to purebred Duroc Jersey and Berkshire pigs for 82 days.
Supplementing the basal ration with 9 percent of the distillers' solubles gave an average daily gain of 1.45 to 1.48 pounds, compared to 1.39 to 1.42 pounds for the 12 percent groups.
The feed consumption for each 100 pounds of gain was less for both the 12 percent dried molasses and potato distillers' solubles groups than for the 9 percent groups. The 9 percent dried corn soluble group required less feed than its corresponding 12 percent group.
The higher average gains at the 9 percent levels, even though more feed is required, may be due to a more palatable ration. Substantiating the probable unpalatability of the 12 percent levels of distillers' solubles is the fact that one group fed a basal ration and dried molasses solubles free-choice consumed no more than 5 pounds of solubles during the entire trial.
