[Objective] The paper was to investigate the effects of adding Shuanghuanglian propolis oral liquid in drinking water on growth performance,slaughter performance and meat quality of broilers. [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 2. 63%( P 0. 05) and 1. 70%( P 0. 05) and 1. 15%( P > 0. 05),respectively; the semi-eviscerated rates were increased by 1. 51%( P 0. 05) and 4. 09%( P 0. 05) and 1. 47%( P > 0. 05),respectively; the redness( a*) were increased by 1. 24%( P 0. 05) and 1. 03%( P 0. 05) and 2. 89%( P < 0. 05),respectively. [Conclusion]Adding 0. 5 and 1. 0 mL / L Shuanghuanglian propolis oral liquid in drinking water could improve growth performance,slaughter performance,meat quality of broilers,and the dose of 1. 0 mL / L is recommended in clinical application.
