Influence of fermented whey protein fractions on the growth performance, haematological traits, serum biochemistry, faecal and caeca microbiota of broiler chickens.

ABSTRACT: Nowadays researchers and consumers are concerned about antibiotic resistance in poultry products causing antibiotic-resistant pathogens. Here, we investigated the effects of fermented whey peptides (FWP) with Limosilactobacillus fermentum (M4) as a nutraceutical supplement on growth performance, blood parameters, relative organs, and metagenomic analysis of broiler chickens, aiming to develop substitute for antibiotics in poultry feeds. An active culture of Lactobacillus fermentum (M4, GenBank Accession Number: MF951096) was inoculated into sterilized cheese whey at a rate of 2% (v/v) (10⁷ CFU/ml) and incubated at 37 °C for 48 h. Ninety-six one-day-old mixed-sex commercial broiler chicks were randomly assigned in a Completely Randomized Design (CRD) experiment with four treatmen
