Harnessing functional feed additives for sustainable production: the role of <i>Bacillus coagulans</i> and <i>Paenibacillus polymyxa</i> mixture in improving production and health of meat-type quails.

ABSTRACT:

Introduction

Despite the widespread interest in using Bacillus spp. as a probiotic in poultry diets, no evidence has been found to support the use of Paenibacillus polymyxa in the diet of Japanese quails. This study examined the effects of supplementing growing Japanese quail with a mixture of Bacillus coagulans and P. polymyxa (Bc+Pp) on their growth performance, antioxidative activity, immunological status, digestive enzymes, caecal microbiota, and blood chemistry.

Methods

Two hundred 1-week-old meat-type quail chicks were divided into four groups at random; five pens, each containing ten birds. These birds were provided with a basic feed as a control group, or a feed diet treated with 0.5, 1.0, and 1.5 mg kg^-1 of Bc+Pp mixture (1:1).
