[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. [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.展开更多
