Feeding Performance and Carcass Characteristics of Growing-Finishing Swine Fed "C" Grade Sugar¹

Florida Agricultural Experiment Station,² Gainesville

Abstract

Six groups of weanling pigs were fed rations containing various levels of "C" sugar. One group was given sugar free-choice with a protein supplement and the remaining groups were fed sugar at levels of 0, 10, 20, 30 and 40% of the ration.

The pigs fed sugar free-choice gained significantly slower than pigs on any of the other ration treatments and were less efficient in feed conversion. Feed consumption was similar for pigs on all treatments.

The dressing percent of pigs fed the 20% and 40% sugar-containing rations was significantly higher than that of the control pigs. Carcass grade was not significantly affected by ration treatment. Livers from pigs fed sugar free-choice or as 40% of the ration had the most desirable flavor.

The pigs fed sugar free-choice had significantly heavier livers, softer carcasses and a higher percent of lean cuts than pigs fed the other rations.
