Prebiotics and the poultry gastrointestinal tract microbiome
Feed additives that can modulate the poultry gastrointestinal tract and provide benefit to bird performance and health have recently received more interest for commercial applications. Such feed supplements offer an economic advantage because they may directly benefit poultry producers by either... Continue reading...

Effects of encapsulated essential oils and organic acids on laying performance, egg quality, intestinal morphology, barrier function, and microflora count of hens during the early laying period
The objective of this study was to investigate the effect of encapsulated essential oils and organic acids (EOA) on the growth performance, egg quality, intestinal morphology and functions, and microbial count of laying hens from week 21 to 30. A total of five hundred and four 21-wk-old layers were... Continue reading...

Withdrawal of antibiotic growth promoters from broiler diets: performance indexes and economic impact
This study aimed to estimate the productive and economic impacts caused by the withdrawal of antibiotic growth promoters (AGP) from broilers diet. Indexed publications that compared diets with or without AGP (AGP+/AGP−) for broilers (from initial to final phase) were collected and the results of... Continue reading...

Administration of dietary prebiotics improves growth performance and reduces pathogen colonization in broiler chickens
Dietary prebiotics are thought to be potentially important alternatives to antibiotic growth promoters in poultry production because of their beneficial performance and health effects. The administration of dietary prebiotics has been demonstrated to improve animal health, growth performance, and... Continue reading...

The effects of feeding yeast bioactives to broiler breeders and/or their offspring on growth performance, gut development, and immune function in broiler chickens challenged with Eimeria
Yeast bioactives (YB) may stimulate broiler breeders (BB) to increase deposition of immunoglobulins (Ig) in eggs. We investigated the effects of feeding YB (mixture of derivatives from whole yeast subjected to enzymatic hydrolysis) to BB and/or their offspring on growth performance, gut development...

Effect of Lemongrass (Cymbopogon citratus) Essential Oil on the Survival of Multidrug-Resistant Salmonella enterica serovar Heidelberg in Contaminated Poultry Drinking Water
Drinking water contaminated with Salmonella could serve as a source for cecal colonization of the pathogen in birds. In this study, we investigated the efficacy of a generally recognized as safe—status essential oil (lemongrass essential oil, LGEO) against multidrug-resistant Salmonella enterica...

Effects of Diutina rugosa SD-17 on growth performance, intestine morphology, and immune status of chickens
Probiotics are considered the preferred alternatives to antibiotics for growth promotion and disease prevention. Previous studies have confirmed that Diutina rugosa SD-17 has the potential as a probiotic. We evaluated the probiotic effect of D. rugosa SD-17 on 360 one-day-old Hy-line brown chickens...

Efficacy of Bacillus subtilis administered as a direct-fed microorganism in comparison to an antibiotic growth promoter and in diets with low and high DDGS inclusion levels in broiler chickens
Direct-Fed Microorganisms (DFM) are potentially important alternatives to antibiotic growth promoters (AGP). We investigated the administration of Bacillus subtilis administration as a DFM in broiler chickens. Comparison of DFM and AGP administration determined the DFM improved BW, BWG, ADFI, and...

Organic Acids and Nature Identical Compounds Can Increase the Activity of Conventional Antibiotics Against Clostridium Perfringens and Enterococcus Cecorum In Vitro
In a global context of increased antibiotic resistance, feed additives with enhanced antimicrobial properties are a useful and increasingly needed strategy. Organic acids (OA) and botanical molecules such as nature identical compounds (NIC) have been shown to be effective against bacterial... Continue reading...

Effects of Direct Fed-Microorganisms and Enzyme Blend Co-Administration on Growth Performance in Broilers Fed Diets With or Without Antibiotics
Direct-Fed Microorganisms (DFM) and exogenous enzymes have been demonstrated to improve growth performance in poultry and are potentially important components of management programs for antibiotic-free (ABF) poultry production. In this study, we evaluated the effect of a feed additive composed of a... Continue reading...
