This study aimed to investigate the effects of dietary supplementation of mixed probiotics on growth performance and fatty acid profiles of Korean native chicken and to provide information regarding producers. Ninety six Korean native chicken (48 males and 48 females, Hanhyup-3-ho) were allocated to 16 wire cages with 4 treatments, 4 replicates and 6 chicks (3 males and 3 females) per wire cage and fed one of four diets containing 0, 0.5, 1 and 1.5% mixed probiotics for 6 weeks. There were no differences among treatments in growth performance of Korean native chicken. For fatty acid profiles, no statistically differences in each fatty acid, total saturated fatty acid and unsaturated fatty acids were observed in all treatments. In the present study, irrespective of statistically differences, inclusion of mixed probiotics tended to improve growth performance, reduce saturated fatty acid and increase unsaturated fatty acids in breast muscles from Korean native chicken compared to controls.
