Effects of Bacillus amyloliquefaciens F1 postbiotics on growth performance, serum biochemistry, intestinal morphology and intestinal microbiota of yellow-feathered broilers.

ABSTRACT: The extensive use of antibiotics in poultry production has contributed to antimicrobial resistance, creating a need for safe and stable alternatives. This study evaluated the effects of Bacillus amyloliquefaciens F1 postbiotics (BAP) on growth performance, antioxidant status, intestinal morphology, and cecal microbiota in yellow-feathered broilers. A total of 360 one-day-old male broilers were randomly and evenly assigned to three dietary treatments for 63 days: a basal diet (control, CON), the basal diet separately supplemented with 100 g/t (BAP100) and 150 g/t (BAP150) of BAP. At 21 days, broilers in BAP-supplemented groups exhibited significantly higher body weight (approximately 7.5 % increase, P < 0.01) and average daily gain (approximately 8 % increase, P < 0.01), with a 9 % reductio
