摘　　要：The effect of supplementation of conjugated linoleic acid （CLA） in diets on growth performance and total lactic bacteria （LAB） in small intestine of broiler. One hundred sixty eight broilers （Arbor Acres; 1 wk old） were randomly assigned to 8 groups. Each group （male 21 and female 21 broiler chickens） was further randomly divided into 3 replicates of 7 chickens were assigned to 4 dietary treatments （0%, 0.5%, 1.0%, and 1.5% CLA）. Feed consumption and BW were recorded at every 7-day period. On day 56, and each week were collected at ileal content in small intestine for the total count of lactic acid bacteria （LAB）. There were highly significant differences in body weight gain, average dairy feed intake, average dairy gain and feed conversion ratio among the treatments （P 〈 0.01）. Moreover, our results revealed that the highest detection trend from the ileal occurred during the period in the supplementation of CLA.
