[Method]Ninety one-day-old broilers were randomly divided into three groups（ group Ⅰ,group Ⅱ and group Ⅲ） ： group Ⅰ was the control group,and groups Ⅱ and Ⅲ were added 0. 5 and 1. 0 mL / L Shuanghuanglian propolis oral liquid in drinking water,respectively.[Result] Compared with broilers in group I,the average daily feed intakes of broilers in group Ⅱ and group Ⅲ were increased by 0. 86%（ P 〉 0. 05） and 1. 10%（ P 〉 0. 05）,respectively; the average daily gains were increased by 2. 33%（ P 〈 0. 05） and 4. 43%（ P 〈 0. 05）,respectively; the feed gain ratios were decreased by 1. 05%（ P 〉0. 05） and 2. 63%（ P 〈0. 05）,respectively; the slaughter rates were increased by 0. 94%（ P 〉0. 05） and 1. 70%（ P 〈0. 05）,respectively; the eviscerated rates were increased by 0. 52%（ P 〉 0. 05） and 1. 15%（ P 〉 0. 05）,respectively; the semi-eviscerated rates were increased by 1. 51%（ P 〈 0. 05） and 2.23%（ P 〈 0. 05）,respectively; the breast muscle rates were increased by 3. 77%（ P 〈 0. 05） and 5. 51%（ P 〈 0. 05）,respectively; the leg muscle rates were increased by 1. 96%（ P 〉 0. 05） and 4. 09%（ P 〈 0. 05）,respectively; the lightness（ L＊） were decreased by 0. 96%（ P 〉 0. 05） and 1. 47%（ P 〉 0. 05）,respectively; the redness（ a＊） were increased by 1. 24%（ P 〈 0. 05） and 1. 86%（ P 〈 0. 05）,respectively; the yellowness（ b＊） were decreased by 0. 44%（ P 〉0. 05） and 1. 03%（ P 〈0. 05）,respectively; the drip losses were decreased by 1. 22%（ P 〈0. 05） and 1. 56%（ P 〈0. 05）,respectively; the cooking losses were decreased by 1. 76%（ P 〉 0. 05） and 2. 89%（ P 〈 0. 05）,respectively.
