A Review of Antimicrobial Resistance in Poultry Farming within Low-Resource Settings
The emergence, spread, and persistence of antimicrobial resistance (AMR) remain a pressing global health issue. Animal husbandry, in particular poultry, makes up a substantial portion of the global antimicrobial use. Despite the growing body of research evaluating the AMR within industrial farming...

Feeding of yeast cell wall extracts during a necrotic enteritis challenge enhances cell growth, survival and immune signaling in the jejunum of broiler chickens
Necrotic enteritis (NE) is one of the most common and costly diseases in the modern broiler industry, having an estimated economic impact of $6 billion dollars annually. Increasing incidents of NE have resulted from restrictions on the use of antibiotic feed additives throughout the broiler... Continue reading...

Effects of star anise (Illicium verum Hook.f) oil on the nuclear factor E2–related factor 2 signaling pathway of chickens during subclinical Escherichia coli challenge
We characterized the mechanism underlying star anise (Illicium verum Hook.f) oil (SAO)–mediated antioxidant status during subclinical Escherichia coli (E. coli) challenge. A total of 512 male birds (White Leghorn) at 30 wk of age with similar body weight (2.14 ± 0.02 kg) were randomly divided into... Continue reading...

Effects of antibiotic-free diet and stocking density on male broilers reared to 35 days of age. Part 2: feeding and drinking behaviours of broilers
The U.S. broiler industry is trending toward antibiotic-free (ABF) production because of increasing concerns on antimicrobial resistance in human medicinal treatments. Given the differences in performance observed between ABF diets and conventional diets, changes in feeding and drinking behaviors... Continue reading...

An approach to alternative strategies to control avian coccidiosis and necrotic enteritis
Consumer demands for chickens raised without the use of antibiotics, legislative restrictions, and trade opportunities have encouraged many integrators within the poultry industry to raise poultry without antibiotic growth promoters (AGPs) and ionophores. However, with the removal of AGPs and... Continue reading...

Production performance, egg quality, and small intestine histomorphology of the laying hens supplemented with phytogenic feed additive
An experiment was conducted to determine the effect of a phytogenic compound (Alquernat Nebsui L [ANL]) applied through drinking water on hen day egg production (HDEP), egg quality, and small intestine histomorphology of Hy-Line W-36 laying hens from 65 to 73 wk of age. A total of 90 hens were... Continue reading...

Growth performance and carcass characteristics of broilers fed diets varying in supplemental copper concentrations from 29 to 53 days of age
High concentrations of dietary Cu have been shown to improve growth performance of broilers raised without antibiotics. A study was conducted to evaluate the effects of feeding high concentrations of dietary Cu to male broilers from 29 to 53 D of age. Broilers received common diets containing 135 ...
