Using combined Lactobacillus and quorum quenching enzyme supplementation as an antibiotic alternative to improve broiler growth performance, antioxidative status, immune response, and gut microbiota
To seek viable alternatives to antibiotics, we determined the combinatorial effects of Lactobacillus and a quorum quenching enzyme (QQE) on broiler growth performance, antioxidant capacity, immune responses, and cecal microbial populations. In total, 360 one-day-old male broilers (Ross 308) were... Continue reading...

Perception of poultry veterinarians on the use of antimicrobials and antimicrobial resistance in egg production
This study aimed to describe the perception of veterinarians who work with commercial laying hens in the state of Rio Grande do Sul, Brazil, regarding the use of antibiotics and their possible impacts on animal, human, and environmental health. A descriptive epidemiological study was carried out... Continue reading...

The combined impact of xylo-oligosaccharides and gamma-irradiated astragalus polysaccharides on the immune response, antioxidant capacity, and intestinal microbiota composition of broilers
The present study investigated the individual and combined effects of xylo-oligosaccharides (XOS) and gamma-irradiated astragalus polysaccharides (IAPS) on the immune response, antioxidant capacity and intestinal microbiota composition of broiler chickens. A total of 240 newly hatched Ross 308... Continue reading...

Bacillus licheniformis–fermented products and enramycin differentially modulate microbiota and antibiotic resistome in the cecal digesta of broilers
Since antibiotic resistance is a global health issues, the use of antibiotics in animal feed for growth promotion has been restricted in many countries. Bacillus licheniformis probiotic is a potential alternative to antibiotics for increasing poultry performance. Through metagenomic sequencing,... Continue reading...

Comparative impact of conventional and alternative gut health management programs on gastrointestinal responses in broiler chickens raised in commercial and research settings
Gut health management programs are developed to support growth performance and livability of broiler chickens reared in the absence of antibiotics. Identifying the impact of gut health management programs on gastrointestinal responses would improve the understanding of how the gastrointestinal... Continue reading...

Effects of feeding a probiotic blend on live performance of broiler chickens from 0 to 49 days of age
Probiotic use has increased as the use of antibiotics in broiler feeds has decreased. This has largely occurred due to a desire to maintain improvements in growth and feed conversion which had typically been observed from subtherapeutic use of antibiotics. As such, two (2) commercially applicable... Continue reading...

Comparative effects of feeding single- and multi-strain probiotics to commercial layers on the productive performance and egg quality indices
This experiment investigated the effects of dietary supplementation of single-strain probiotic (SSP) containing Bacillus subtilis 2 × 109 cfu/g and multi-strain probiotic (MSP) containing Lactobacillus acidophilus 3 × 107–108 cfu/g, Bacillus subtilis 3 × 107-108 cfu/g, and Saccharomyces cerevisiae...
