Effects of nanoencapsulated cumin essential oil as an alternative to the antibiotic growth promoter in broiler diets
The effects of nanoencapsulated cumin essential oil (EO) feeding broilers on growth performance, mucin 2 gene expression, blood parameters, and immune responses to phytohemagglutinin (PHA) and 2, 4-dinitrochlorobenzene (DNCB) were evaluated. In a completely randomized design, 1050 male day-old Ross... Continue reading...

Administration of Bacillus cultures as direct-fed microorganisms improves growth performance and reduces mortality of broilers raised under performance-reducing stress challenge
The use of direct-fed microorganisms (DFM) is an important alternative to antibiotic growth promoters (AGP) for improving growth and managing disease in poultry production. We investigated the administration of 2 multistrain Bacillus cultures administered as DFM on growth performance and mortality... Continue reading...

Administration of direct-fed Bacillus cultures and refined functional carbohydrates to broiler chickens improves growth performance and promotes positive shifts in gastrointestinal microbiota
Due to regulation and consumer-driven decreases in the use of antibiotics, there is a critical need for the development of alternatives to antibiotic growth promoters (AGP) for use in poultry production. Direct-fed microorganisms (DFM) and prebiotics, which have been demonstrated to improve growth... Continue reading...

Changes in antibiotic resistance of Escherichia coli during the broiler feeding cycle
The purpose of this study was to investigate the drug-resistant phenotypes and genes of Escherichia coli in animal, environmental, and human samples before and after antibiotic use at a large-scale broiler farm to understand the respective effects on E. coli resistance during the broiler feeding...

Effects of antibacterial peptide combinations on growth performance, intestinal health, and immune function of broiler chickens
To study the effects of antibacterial peptides (ABPs) on feeding broilers, this experiment compared the 2 combinations of ABP with antibiotics by separately adding the supplement to the diet of 818 broilers as follows—antibiotics, Pratt and Full-tide, and Pratt and plant essential oil—and then the...

Sustainable Antibiotic-Free Broiler Meat Production: Current Trends, Challenges, and Possibilities in a Developing Country Perspective
Antibiotic-free broiler meat production is becoming increasingly popular worldwide due to consumer perception that it is superior to conventional broiler meat. Globally, broiler farming impacts the income generation of low-income households, helping to alleviate poverty and secure food in the... Continue reading...

Sodium bisulfate feed additive aids broilers in growth and intestinal health during a coccidiosis challenge
Sodium bisulfate (SB) was evaluated on its ability to improve broiler growth and intestinal structure with(out) a coccidia challenge. One thousand two hundred Cobb500 day-old males were randomly assigned within 4 experimental groups with a 2 × 2 factorial design, with (out) SB in the diet and with(... Continue reading...

Dietary supplementation with fermented defatted “alperujo” induces modifications of the intestinal mucosa and cecal microbiota of broiler chickens
Nutraceuticals are not only nutritionally beneficial for animals but also their use as feed supplements may reduce environmental contamination. The effect of fermented defatted “alperujo,” an olive oil by-product, supplementation on the intestinal health of broiler chickens was assessed by... Continue reading...

Saccharomyces boulardii attenuates inflammatory response induced by Clostridium perfringens via TLR4/TLR15-MyD8 pathway in HD11 avian macrophages
Macrophages are professional phagocytic cells that play a critical role in initiating immune responses by presenting antigen and phagocytic clearance. The macrophages can be targeted for immunomodulation by beneficial microbes, such as probiotics. The aim of this study is to investigate the... Continue reading...
