This study was conducted to evaluate the effects of chelated Cu and Zn on growth performance, nutrient digestibility, blood profiles, and fecal noxious gas emission in weanling pigs. A total of 90 weanling pigs with an initial body weight (BW) of $5.27{\pm}0.04kg$ were randomly allotted to two dietary treatments for 42 d. Pigs were then fed a control diet (CON) or a Zinpro diet (CON + 0.1% chelate copper and zinc). There were nine replicate-pens with five pigs in each pen. During d 0 to 14 and d 14 to 28, the ADFI decreased (p<0.05) and the G/F increased (p<0.05) in pigs fed the Zinpro diet compared with those that received the CON diet. During d 28 to 42, the ADFI increased (p<0.05) in pigs fed the Zinpro diet relative to those fed the CON diet. Additionally, the apparent total tract digestibility of DM, N, and energy increased (p<0.05) in the Zinpro group when compared to the CON group on d 14 and 28. The lymphocyte percentage was also greater (p<0.05) in the Zinpro group than in the CON group. Overall, dietary supplementation with 0.1% chelate copper and zinc improved the growth performance and nutrient digestibility in weanling pigs.
