Productivity and Well-Being of Broiler Chickens Supplemented With Probiotic
Efficiency in poultry production is based on the balance between nutrition, intestinal health, and animal welfare. With increasing consumer demand for antibiotic suppression of animal feed for growth, the animal nutrition segment has sought new alternatives to optimize production rates and, based...

The Intestinal Cinnamaldehyde Release and Antioxidative Capacity of Broiler Chickens Fed Diets Supplemented with Coated Oleum Cinnamomi
Oleum cinnamomi (OCM, cinnamon oil), which is produced by aromatic cinnamon plants, is increasingly used as a feed additive to animal diets. OCM is a natural product rich in polyphenolic compounds that exhibit strong antioxidative property. However, the direct addition of OCM to the feed is... Continue reading...

Effect of Bacillus subtilis DSM 32315 on the intestinal structural integrity and growth performance of broiler chickens under necrotic enteritis challenge
The effect of dietary inclusion of Bacillus subtilis DSM 32315 on the intestinal health and growth performance of Cobb 500 male broilers subjected to a Clostridium perfringens- induced necrotic enteritis (NE) challenge was determined in 2 experiments. In experiment 1, chicks were randomly assigned... Continue reading...

Growth performance and gastrointestinal responses in heavy Tom turkeys fed antibiotic free corn−soybean meal diets supplemented with multiple doses of a single strain Bacillus subtilis probiotic (DSM29784)
Growth performance and gastrointestinal (GIT) responses to a single-strain of Bacillus subtilis (SSB) were investigated using 960 Hybrid Converter Toms. A total of 4 iso-caloric and iso-nitrogenous corn−soybean meal-based diets were allocated to 12 replicate cages/pens and fed (ad libitum) in a... Continue reading...

Effect of dietary supplementation of Bacillus subtilis DSM29784 on hen performance, egg quality indices, and apparent retention of dietary components in laying hens from 19 to 48 weeks of age
The aim of the current study was to evaluate egg production, quality, and apparent retention (AR) of components in response to a multi-dose application of a single strain Bacillus subtilis (SSB; DSM29784) in a corn-soybean meal basal diet fed to hens (19 to 48 wk of age). The treatments consisted... Continue reading...

Implication of the knowledge and perceptions of veterinary students of antimicrobial resistance for future prescription of antimicrobials in animal health, South Africa
Understanding the knowledge and perceptions of veterinary students of antimicrobial resistance (AMR) as potential future prescribers of antimicrobials may serve as an opportunity to improve stewardship of AMR. Pre-final (n = 42) and final (n = 29) year veterinary students of the University of... Continue reading...

Effects of probiotics Lactobacillus plantarum 16 and Paenibacillus polymyxa 10 on intestinal barrier function, antioxidative capacity, apoptosis, immune response, and biochemical parameters in broilers
This study aimed to investigate the effects of Lactobacillus plantarum 16 (Lac16) and Paenibacillus polymyxa 10 (BSC10) on intestinal barrier function, antioxidative capacity, apoptosis, immune response, and biochemical parameters in broilers. A total of 540 one-day-old broiler chicks (Cobb 500)... Continue reading...

Effect of prebiotic and synbiotic supplementation in diet on growth performance, small intestinal morphology, stress, and bacterial population under high stocking density condition of broiler chickens
The current study investigated the effect of prebiotic mannan-oligosaccharide (MOS) and synbiotic (MOS mixed with Bacillus subtilis and Bacillus licheniformis) on growth performance and bacterial population under high stocking density (HSD) conditions in broilers. A total of 605 one-day-old male... Continue reading...

Bacillus amyloliquefaciens CECT 5940 alone or in combination with antibiotic growth promoters improves performance in broilers under enteric pathogen challenge
A study was conducted to investigate the effects of Bacillus amyloliquefaciens CECT 5940 as a direct-fed microbial (DFM) alone or in association with bacitracin methylene disalicylate (BMD) in broilers under enteric pathogen challenge. A total of 1,530-day-old male Cobb500 chicks were randomly... Continue reading...

Nucleotide-rich yeast extract fed to broiler chickens challenged with Eimeria: impact on growth performance, jejunal histomorphology, immune system, and apparent retention of dietary components and caloric efficiency
Nucleotide-rich yeast extract (YN) was investigated for its effects on growth performance, jejunal histomorphology and mucosal immunoglobulin A (IgA), immune organs weight and apparent retention (AR) of components in broiler chickens challenged with Eimeria. A total of 336 day-old male chicks (Ross... Continue reading...
