Probiotic <i>Lactocaseibacillus casei</i> NK1 Enhances Growth and Gut Microbiota in Avian Pathogenic <i>Escherichia coli</i> Challenged Broilers.

ABSTRACT: The present study was conducted to assess the efficacy of Laboratory-Isolated Lactocaseibacillus casei NK1 (Lc. NK1) in broilers hypothesizing that, Lc. NK1 supplementation will enhance growth performance, modulate the gut microbiome, and reduce fecal pathogenic Escherichia coli in broilers. The experiment spanned 35 days where 60 one-day-old broiler chicks were randomly assigned to four treatment groups (n = 15); control-group with no treatment (NC), APEC (challenged with E. coli only), CProb (received commercial probiotics), and LNK1 (treated with Lc. NK1). The APEC, CProb, and LNK1 groups were infected with E. coli O78 strain at 11 days of age. Growth performance analysis revealed that the LNK1 group by day 35 gained body weight similar to the CProb gr
