Technical Abstract: Two assays were conducted to determine the effects of dietary electrolyte balance dEB) and molasses in diets with corn-based distiller’s dried grains with solubles (DDGS, Sioux River Ethanol, Hudson, SD) on growth performance of nursery and finishing pigs. For the first experiment, 126 nursery pigs (35 days old and avg BW of 10.2 kg) were assigned with six pigs/pen and seven pens/treatment. Treatments were a corn-soybean meal-based control and diets with DDGS as 30% of the formula without and with 0.93% sodium bicarbonate to bring dEB to 64 meq/kg [(n=Na + K) x (Cl + S)] as in the control. Diets were formulated to 1.4% Lys, 0.75% Ca, and 0.35% available P. Pigs fed the control diet had greater ADG (P < 0.03) and ADRI (P < 0.08) but did not differ in G:F (P > 0.6) compared to those fed diets with DDGS. Addition of sodium bicarbonate did not improve growth performance (P > 0.3). For the second experiment, a total of 70 gilts (avg BW of 60.5 kg) were assigned with two pigs/pen and five pens/treatment. The pigs were fed the experimental diets for 26 days, fed a common diet for 6 days, and then reassigned to a different treatment for an additional 26-day assay. The end result was 10 pens per treatment. Treatments were a corn-soybean meal-based control and diets with DDGS as 40% of the formula without and with 5% molasses and sodium bicarbonate (none, 1, and 2%) arranged as a 2 x 3 factorial plus control. Diets were formulated to 0.9% Lys, 0.6% Ca, and 0.22% available P. Pigs fed the control diet had greater ADG and ADFI (P <0.001) but did not differ in G:F (P >0.4) compared to those fed diets with DDGS. Adding molasses and(or) sodium bicarbonate did not affect ADG (P > 0.5) or ADFI (P > 0.14) and adding molasses actually decreased (P < 0.03) G:F. In conclusion, adding sodium bicarbonate and(or) molasses to diets with DDGS did not improve growth performance in nursery or finishing pigs.
