Dietary Lactobacillus plantarum improves the growth performance and intestinal health of Pekin ducks.

ABSTRACT: Lactobacillus plantarum (LP) contributes to the intestinal health, whereas the study about the effects of LP on Pekin ducks is lacking. This study aimed to investigate the effects of LP on growth performance and intestinal health of Pekin ducks. A total of 180 one-day-old birds were randomly allotted to 3 treatments, and ducks were fed with a basal diet (Control) or basal diet supplemented with 400 (LP1) and 800 (LP2) mg/kg LP (5 × 10⁹ CFU/g). The animal trial lasted for 42 d. Results showed that the LP1 and LP2 treatments improved growth performance (feed conversion) of ducks during the period of 1 to 42 d. At the end of 21 d, the decreased serum levels of interleukin (IL)-1β, interferon (IFN)-γ as well as downregulated ileal mRNA expression of IL-1β were observed in 2 doses of
