This experiment investigated the influence of different synbiotic processing methods on the intestinal bacterial count, morphology and histological status of developed male Mandarah chicks. Two hundred and ten male Mandarah line chicks aged 1 d were randomized to receive one of 7 chicks. The method and dose for 1-time synbiotics administration to the day-old chicks were as follows: G1: chicks on basal diet received no treatment (control); G2: 0.25 mL synbiotics sprayed; G3: 0.50 mL synbiotics sprayed; G4: 0.25 mL of synbiotics are added to drinking water; G5: 0.50 mL of synbiotics are added to drinking water; G6: 0.25 mL of synbiotics dripped into the mouth; and G7: 0.50 mL of synbiotics dripped into mouth drops. Lactic acid bacteria(LAB) were significantly increased (P<0.0001) compared to the control group and other treated groups and had the maximum values after the use of synbiotics via drinking water (0.25 or 0.50 mL). Furthermore, when comparing the treated birds (G4, G5) with the control birds, the Escherichia coli concentration in the drinking water containing synbiotics was significantly lower. In addition, treated chickens at (G7) showed a higher duodenum, ileum villus height (VH), and VH. - Ileum crypt depth (CD) ratio compared to other groups. In addition, birds treated with 0.50 mL of synbiotics in drinking water (G5) performed better in duodenum, ileum, CD and VH. - CD ratio than the other groups. Meanwhile, intestinal tract length and visceral pH did not differ significantly between groups. It can be concluded that the use of 0.25 mL of synbiotics in drinking water can improve the overall health of birds.
本实验研究了不同共生加工方法对发育雄性曼达拉鸡肠道细菌计数、形态和组织学状态的影响。将 210 只 1 日龄雄性曼达拉鸡随机分为 7 组，每只鸡接受以下 1 次共生处理方法和剂量：G1：基础日粮组不接受处理（对照）；G2：喷 0.25 mL 共生；G3：喷 0.50 mL 共生；G4：在饮水中添加 0.25 mL 共生；G5：在饮水中添加 0.50 mL 共生；G6：将 0.25 mL 共生滴入口腔；G7：将 0.50 mL 共生滴入口服滴剂。与对照组和其他处理组相比，乳酸菌（LAB）显著增加（P<0.0001），且使用饮水（0.25 或 0.50 mL）共生后达到最大值。此外，与对照组相比，含共生的饮水组（G4、G5）大肠杆菌浓度显著降低。此外，与其他组相比，（G7）处理鸡的十二指肠、回肠绒毛高度（VH）和 VH。-回肠隐窝深度（CD）比值更高。此外，用饮水（G5）添加 0.50 mL 共生的鸡在十二指肠、回肠、CD 和 VH 方面表现更好。-CD 比值优于其他组。同时，各组肠道长度和内脏 pH 无显著差异。可以得出结论，在饮水中使用 0.25 mL 共生可以改善鸡的整体健康状况。
