Antibacterial and antibiofilm activity of Lagotis brachystachya extract against extended-spectrum β-lactamases-producing Escherichia coli from broiler chickens
Lagotis brachystachya Maxim (L. brachystachya) is an herb widely used in traditional Tibetan medicine. In the present study, the antibacterial activity of L. brachystachya extract to extended-spectrum-lactamases (ESBLs)-producing E. coli was determined by Kirby-Bauer disc diffusion, minimum...

Effects of Bacillus subtilis, butyrate, mannan-oligosaccharide, and naked oat (ß-glucans) on growth performance, serum parameters, and gut health of broiler chickens
Four nonantibiotic alternative growth promoters for broiler chickens were evaluated. Ross 308 chicks were fed a control diet (mainly corn and soybean meal) or a diet supplemented with a probiotic (Bacillus subtilis Gallipro DSM 17299), encapsulated butyric acid (Novyrate C), mannan-oligosaccharide...

Antimicrobial resistance and genetic diversity of Enterococcus faecalis from yolk sac infections in broiler chicks
Despite restrictions on the use of antibiotics in poultry, the percentage of multidrug resistant bacteria, isolated from both adult birds and chicks, remains high. These bacteria can spread between countries via hatching eggs or chicks. Antibiotic resistant bacteria can also pose a threat to... Continue reading...

Knowledge on diseases, practices, and threats of drugs residues in chicken food chains in selected districts of Dodoma region, Tanzania
Raising chickens is a rapidly growing subsector in the livestock industry. However, low biosecurity results in increased disease spread and the use of drugs in chicken flocks. Increased use of drugs threatens public health, as it poses risks of drug residues and resistant pathogens escaping into... Continue reading...

Effects of direct-fed microbial (Bacillus subtilis C-3102) inclusion on tom turkey production efficiency and intestinal microbial populations
Dietary inclusions of direct-fed microbials (DFM) are becoming more common as antimicrobial use for growth promotion is no longer approved. Effects of various DFM on poultry performance have been studied; however, limited research has been conducted on the use of Bacillus subtilis C-3102 (Calsporin... Continue reading...

Xylanase impact beyond performance: a prebiotic approach in broiler chickens
Microbiome plasticity in chickens provides an attractive target for future potential therapeutic platforms. However, a better understanding of the chicken microbial ecology and how interventions such as xylanase addition can modulate this is needed. Interest in xylanase as an essential additive for...

Progress on Gut Health Maintenance and Antibiotic Alternatives in Broiler Chicken Production
The perturbation of gut health is a common yet unresolved problem in broiler chicken production. Antibiotics used as growth promoters have remarkably improved the broiler production industry with high feed conversion efficiency and reduced intestinal problems. However, the misuse of antibiotics has... Continue reading...

Antimicrobial Resistance and Poultry Production in Developing Countries (P3728)
Antibiotics are natural, synthetic, or semi-synthetic substances that kill or interfere with the growth of microorganisms, specifically bacteria. They are used to treat or prevent infections in humans and animals. Antimicrobial drugs, such as antibiotics, are essential to protecting animal health... Continue reading...

Impacts of tea tree or lemongrass essential oils supplementation on growth, immunity, carcass traits, and blood biochemical parameters of broilers reared under different stocking densities
The effects of tea tree essential oil (TTEO) and lemongrass essential oil (LGEO) with different stocking densities on the growth performance, biochemical markers, antioxidants, and immunity state of broiler chickens were studied. Birds were housed at stocking densities of 25, 30, 35, and 40 kg/m2... Continue reading...

The effects of a quillaja and yucca combination on performance and carcass traits of coccidia-vaccinated broilers exposed to an enteric disease challenge
A series of 6 floor pen trials was conducted to determine the effects of a quillaja and yucca combination product on the performance and carcass traits of growing broiler chickens vaccinated for coccidiosis at the hatchery. In each of the trials graded levels (0, 250, and 500 ppm) of a quillaja and... Continue reading...
