Alternatives to Antibiotics

Avian coccidiosis and anticoccidial potential of garlic (Allium sativum L.) in broiler production: a review

Evaluation of probiotic and glutamine in ovo on broilers challenged with Salmonella Heidelberg

Raising broiler chickens without ionophore anticoccidials

Effects of synbiotic supplementation as an antibiotic growth promoter replacement on cecal Campylobacter jejuni load in broilers challenged with C. jejuni

Differential effects of Bacillus subtilis– and Bacillus licheniformis–fermented products on growth performance, intestinal morphology, intestinal antioxidant and barrier function gene expression, cecal microbiota community, and microbial carbohydrate-acti

This study investigated the differential effects of Bacillus subtilis–fermented products (SFPs) and Bacillus licheniformis–fermented products (LFPs) on the growth performance, intestinal morphology, intestinal gene expression, cecal microbiota community, and microbial carbohydrate-active enzyme...

Effects of a postbiotic, with and without a saponin-based product, on turkey performance

Modern poultry production relies on an ability to prevent and mitigate challenges to bird health, while maintaining a productive bird. A number of different classes of biologics-based feed additives exist, and many have been tested individually for their impacts on poultry health and performance.... Continue reading...

Orally delivered Bacillus subtilis expressing chicken NK-2 peptide stabilizes gut microbiota and enhances intestinal health and local immunity in coccidiosis-infected broiler chickens

We recently reported a stable Bacillus subtilis-carrying chicken NK-lysin peptide (B. subtilis-cNK-2) as an effective oral delivery system of an antimicrobial peptide to the gut with therapeutic effect against Eimeria parasites in broiler chickens. To further investigate the effects of a higher... Continue reading...

Impacts of supplemental Ginkgo biloba oil on broilers’ growth, blood indices, intestinal and hepatic morphology and expression of growth-related genes

The current work examined the impact of Ginkgo biloba oil (GBO) on growth performance, some biochemical parameters, intestinal and hepatic morphology, economic efficiency and expression of some growth-related genes in broiler chickens. A total of 135 chicks (Cobb 500) were allotted into three... Continue reading...

The effect of Bacillus subtilis and its delivery route on hatch and growth performance, blood biochemistry, immune status, gut morphology, and microbiota of broiler chickens

This study evaluated the effect of probiotics (Bacillus subtilis fermentation extract) and its delivery route (in-feed or in ovo) on hatch and growth performance, blood biochemistry, immune status, gut morphology, and microbiota of broiler chickens. Hatching eggs were incubated for 21 d. On d 12,... Continue reading...

Β-glucans and MOS, essential oil, and probiotics in diets of broilers challenged with Eimeria spp. and Clostridium perfringens

The aim of this study was to evaluate the effectiveness of β-glucans and MOS, essential oil (mixture of carvacrol and thymol), and the probiotic based on Saccharomyces boulardi, as an alternative to anticoccidial agents. In this experiment, six hundred seventy-two 1-day-old male broiler chicks were... Continue reading...
