ABSTRACT The objective of this experiment was to evaluate the effect of molasses as a substitute for corn in diet on growth performance, nutrient digestibility, blood characteristics, fecal noxious gas emission, and meat quality in finishing pigs. A total of 120 [(Landrace × Yorkshire) × Duroc] pigs with an average initial body weight (BW) of 54.21±2.62 kg were used in this experiment. Pigs were randomly assigned to 1 of the 3 dietary treatments on the basis of BW and sex (10 replicate pens per treatment with four pigs per pen: two gilts and two barrows in each pen). The experiment was divided into two phases: 0-5 weeks and 6-10 weeks. Dietary treatments were as follows: control, basal diet; control + 2.5% cane molasses; and control + 5% cane molasses. No significant differences were observed in terms of growth performance, nutrient digestibility, red blood cells, and white blood cells in blood characteristics, fecal noxious gas emission, and meat quality in this study. However, blood lymphocytes were higher with control + 2.5% cane molasses than with control at the end of the 10th week. Molasses can be considered an alternative for corn at the level of 2.5% without any negative influence in finishing pigs.
