SUMMARY Sumac (Rhus coriaria) is a potential feed supplement, which contains highly bioactive compounds with strong antimicrobial, antioxidant, antifungal and anti-inflammatory properties. Sumac fruits have a wide range of beneficial effects on the productive performance of poultry. At approximately 0.2% inclusion level, sumac improved broiler growth and feed efficiency by 3% and 4%, respectively. Sumac has been shown to improve gut morphology, decrease Escherichia coli population and increase Lactobacillus spp. microbial populations in the digestive tract, and enhance digestibility of nutrients by 6%. The antioxidant activity in sumac has beneficial effects on broilers reared under stressful conditions, where it can prevent deterioration of meat characteristics during storage. However, a lack of research with laying hens means that no conclusions to be drawn about potential beneficial effects on egg production criteria (e.g. egg weight, egg mass) or quality parameters (e.g. shell, Haugh units, yolk index or yolk colour), although cholesterol level of eggs was reduced when sumac was used in layer feed.

在家禽日粮中添加漆树（Rhus coriaria）

总结漆树（Rhus coriaria）是一种潜在的饲料添加剂，它含有高度生物活性的化合物，具有很强的抗菌、抗氧化、抗真菌和抗炎特性。漆树果实对家禽的生产性能具有广泛的有益影响。在大约 0.2% 的添加水平下，漆树分别使肉鸡生长和饲料效率提高了 3% 和 4%。漆树已被证明可以改善肠道形态，减少大肠杆菌数量并增加乳杆菌属。消化道中的微生物种群，并将营养物质的消化率提高 6%。漆树中的抗氧化活性对在压力条件下饲养的肉鸡有好处，它可以防止肉在储存过程中的特性变质。然而，
