The aim of this study was to determine the influence of dietary supplementation with propolis and bee pollen on the intestinal morphology and absorptive surface areas of chickens. Two hundred day-old Ross 308 chickens (100 male and 100 female) were equally allocated into five groups. Throughout the whole study, the control group of chickens was fed with a basal diet, while the experimental groups of chickens were fed with the same diet supplemented with propolis and bee pollen: P1 = 0.25 g of propolis/kg + 20 g of bee pollen/kg; P2 = 0.5 g of propolis/kg; P3 = 1.0 g of propolis/kg; P4 = 20 g of bee pollen/kg. The duodenal villi of chickens from all experimental groups were significantly higher and wider ( < 0.001), while their duodenal villi crypts were significantly deeper ( < 0.001) in comparison with these parameters in chickens from the control group. The villus height to crypt depth ratio, as well as the absorptive surface areas of broiler chickens, were significantly increased ( < 0.001) in experimental groups of chickens in comparison with the control group. These findings suggest that dietary supplementation with propolis and bee pollen has a beneficial effect on broilers chickens' intestinal morphophysiology.
本研究的目的是确定日粮中添加蜂胶和蜂花粉对鸡肠道形态和吸收表面积的影响。200只1日龄的罗斯308肉鸡（100只雄性和100只雌性）被平均分为五组。在整个研究过程中，对照组的鸡饲喂基础日粮，而实验组的鸡饲喂添加了蜂胶和蜂花粉的相同日粮：P1 = 0.25克蜂胶/千克 + 20克蜂花粉/千克；P2 = 0.5克蜂胶/千克；P3 = 1.0克蜂胶/千克；P4 = 20克蜂花粉/千克。与对照组鸡的这些参数相比，所有实验组鸡的十二指肠绒毛显著更高、更宽（<0.001），而它们的十二指肠绒毛隐窝显著更深（<0.001）。与对照组相比，实验组肉鸡的绒毛高度与隐窝深度比值以及吸收表面积显著增加（<0.001）。这些发现表明，日粮中添加蜂胶和蜂花粉对肉鸡的肠道形态生理学有有益影响。
