Impact of early postbiotic supplementation on broilers’ responses to subclinical necrotic enteritis

Year: 2024

Type: article

Abstract: CFU/mL/bird of C. perfringens on d 19 and d 20. Hatchability, weekly performance, intestinal lesion scores, and mRNA abundance of nutrient transporters in the jejunum and ileum were assessed. Data were analyzed by 2-way ANOVA in JMP and significance between treatments identified by LSD test (P ≤ 0.05). A significant postbiotic treatment and NE challenge interaction was observed in performance during d 21-28 with a greater ADG in PIW compared to NC and PIW+. Lesion scores in the jejunum and ileum were significantly reduced in PIW+ compared to NC+. On d 7, mRNA abundance of SGLT1 was significantly greater in PIW compared to the NC group. On d 14, birds in PIW had greater levels of GLUT2 and EAAT3 than NC group. No significant interaction effects were observed on d 21. PIW+ had significantly greater EAAT3 mRNA levels compared to PIW in jejunum and PIW and NC+ in ileum on d 28. In conclusion, in ovo and water supplementation of this postbiotic presents a potential to improve the performance, ameliorate pathology detriments associated with NE, and positively regulate the mRNA levels of key nutrient transporters during NE challenge.
