This study aimed to compare the effects of dietary supplementation of bacteriophage (BP) and acidifiers on performance, meat quality, morphology, and intestinal microbiota in chickens challenged and unchallenged with Salmonella enteritidis (SE) and also to investigate the possibility of replacing them in the diet with antibiotics. A total of 1760 male Ross (308) chicks were randomly assigned to 11 dietary treatments (8 pens/with 20 male chickens in each). Dietary treatments were as follows: SE-uninfected (negative control (NC), a basal diet without supplemention; NC+ 500 g/t BP (NBP1); NC+ 1000 g/t BP (NBP2); NC+ 300 mg/kg acidifier A (NAA); NC+ 300 mg/kg acidifier B (NAB)) and SE-infected (positive control (PC), a basal diet without supplemention; PC+ 40 mg/kg Antibiotic enrofloxacin (PA); PC+ 500 g/t BP (PBP1); PC+ 1000 g/t BP (PBP2); PC+ 3000 mg/kg acidifier A (PAA); PC+ 3000 mg/kg acidifier B (PAB)).

Porcine epidemic diarrhoea virus (PEDV) is a porcine enteric coronavirus, outbreaks and epidemics of which have caused huge economic losses to the livestock industry. The disadvantage of existing PEDV vaccines is that the unstable efficacy and high cost limit their widespread use. Therefore, there is an urgent need to develop a recombinant transgenic vaccine candidate for PEDV.

Interactions between bacteriophages with mammalian immune cells are of great interest and most phages possess at least one molecular pattern (nucleic acid, sugar residue, or protein structure) that is recognizable to the immune system through pathogen associated molecular pattern (PAMP) receptors (i.e., TLRs).
