Intravaginal injection of Lactobacillus johnsonii may modulates oviductal microbiota and mucosal barrier function of laying hens.

ABSTRACT: The avian oviduct connects to the gastrointestinal tract through cloaca, where it is exposed to pathogenic bacteria from intestinal contents. Therefore, improvement of mucosal barrier function in the oviduct is important for safe poultry production. Lactic acid bacteria are known to contribute to strengthening the mucosal barrier function in the intestinal tract, and a similar effect is expected in the oviduct mucosa of chickens. This study aimed to clarify the effects of vaginal administration of lactic acid bacteria on the mucosal barrier function of the oviduct. White Leghorn laying hens (500-days old) were intravaginally administered 1 mL of Lactobacillus johnsonii suspension (1 × 10⁵ and 1 × 10⁸ cfu/mL: low concentration of Lactobacillus (LL) and high concentrati
