Pigs were allotted to 1 of 6 treatments in a completely randomized design with 5 pigs per pen and 12 pens per treatment. Treatment diets were fed in two phases (d 0 to 7 and 7 to 21) followed by a common diet fed d 21 to 45. Treatments included a positive control diet with ZnO, negative control without ZnO, and negative control with 4% wheat bran and formulated to contain 21, 19.5, 18, or 16.5% CP. All diets contained 1.35% SID lysine except the 18 and 16.5% (1.25 and 1.20% lysine) CP diets. Data were analyzed using the lmer function from the lme4 package in R. During the experimental period, decreasing CP decreased (linear, P< 0.05) ADG, G:F, and d 21 BW, but increased (linear, P=0.005) fecal DM%. Pigs fed the diet containing ZnO had increased (P< 0.050) ADG, ADFI, and G:F compared to the negative control and diet with 21% CP and wheat bran. From d 21 to 45, pigs previously fed the 21% CP diet with wheat bran had increased (P< 0.05) ADG compared to the positive control. Fecal DM on d 45 and G:F increased (P< 0.05) for pigs fed the 21% CP, wheat bran diet and negative control compared to those fed the positive control. Overall, pigs fed low CP diets had decreased (P< 0.05) ADG while pigs fed the positive control had greater (P< 0.05) ADG compared to the negative control. Additional research is needed to determine if modifying low CP, wheat bran diets will elicit benefits of increased fecal DM% while maintaining growth performance.
