Effects of Colombian oregano essential oil (Lippia origanoides Kunth) and Eimeria species on broiler production and cecal microbiota
The gut microbiota has an important effect on poultry health and production. The aim of this study was to evaluate the effect of Colombian oregano (COO), Lippia origanoides Kunth, essential oil supplementation on broiler chicken performance and their cecal bacterial microbiome by 16S-based...

The Growth Performance, Meat Quality, and Gut Bacteria of Broilers Raised with or without Antibiotics and Green Tea Powder
This study was to investigate whether green tea powder can be directly used as a feed additive for broiler production. Arbor Acres male broilers (n = 288) were randomly allocated to 4 dietary treatments consisting of 6 replicates with 12 broilers each in a completely randomized design. The 4... Continue reading...

Effects of wild blueberry (Vaccinium angustifolium) pomace feeding on gut microbiota and blood metabolites in free-range pastured broiler chickens
There is a need to develop cost-effective approaches to modulate gut microbiota, promote bird health, and prevent infections in pasture-raised broiler chickens. The present study evaluated the efficacy of organic wild blueberry (Vaccinium angustifolium) also called low-bush blueberry pomace (LBBP)-... Continue reading...

The impact of Bacillus subtilis DSM 32315 on the pathology, performance, and intestinal microbiome of broiler chickens in a necrotic enteritis challenge
It was hypothesized that dietary inclusion of Bacillus subtilis DSM 32315 could inhibit Clostridium perfringens induced necrotic enteritis (NE), thereby improving broiler performance. Male, d 0 chicks were randomly assigned 14 birds/pen, 11 pens/treatment in 3 treatments: a basal diet (control), a... Continue reading...

Effects of Yucca schidigera-derived saponin supplementation during a mixed Eimeria challenge in broilers
An experiment was conducted to determine if dietary Yucca-derived saponin supplementation could ameliorate the immune and growth responses of broilers during a mixed coccidian challenge. A total of 576 two-day-old male Ross 308 broiler chicks were housed in galvanized starter batteries and randomly... Continue reading...

Effect of the flavonoid baicalein as a feed additive on the growth performance, immunity, and antioxidant capacity of broiler chickens
Baicalein, the main flavonoid extracted from the root of Scutellaria baicalensis Georgi, has been demonstrated to exert multiple pharmacological effects, and thus could be utilized as a potential feed additive in broiler chickens. This study evaluated the effects of broiler chicken diet... Continue reading...

Effects of dietary supplementation of microencapsulated Enterococcus fecalis and the extract of Camellia oleifera seed on laying performance, egg quality, serum biochemical parameters, and cecal microflora diversity in laying hens
The aim of this study was to investigate the effects of microencapsulted Enterococcus faecalis (MEF) and the extract of Camellia oleifera seed (ECOS) on laying performance, serum biochemical parameters, and cecal microflora diversity in laying hens. A total of 180 Hy-Line Brown laying hens, 26-wk-... Continue reading...

Effect of a Competitive Exclusion Culture in a Necrotic Enteritis Challenge Model in Broilers
Restrictions on the use of antibiotics in broiler chicken production have led to a resurgence in necrotic enteritis (NE) and heightened interest in non-antibiotic alternatives to control the problem. Probiotics, which are beneficial bacteria that improve the enteric microbial balance, and which... Continue reading...

Bacillus subtilis 29784 induces a shift in broiler gut microbiome toward butyrate-producing bacteria and improves intestinal histomorphology and animal performance
The study reports the effects of Bacillus subtilis 29784 on broiler performance. A total of 1,600 one-day-old Cobb 500 male broiler chicks received either a control diet or the same diet to which B. subtilis 29784 spores were added (1E8 CFU/kg of feed). The birds were slaughtered at 42 D of age.... Continue reading...
