Abstract

The purpose of this study was to investigate the effects of condensed molasses fermentation solubles (CMS) on the growth performance, nutrient digestibility, and backfat thickness of growing pigs. In an eight-week trial, a total of 120 cross-bred ([Landrace × Yorkshire]× Duroc) growing pigs with an average initial body weight (BW) of 25.84 ± 1.60 kg were used. The pigs were randomly assigned to one of two dietary treatments based on body weight and sex. The dietary treatments were as follows: CON - corn-soybean meal-based basal diet (CON) + 2% molasses; and TRT1 - CON + 2% CMS. Each treatment had 12 replicates with five pigs (three gilts and two castrated barrows) per pen. Though there were no significant differences observed in terms of the growth performance and nutrient digestibility (p < 0.05), the backfat thickness in pigs fed 2% CMS tended to increase in week 4 (p < 0.1). Thus, 2% CMS could be optimal to replace molasses given that it does not exert any adverse effects on the performance of growing pigs.
