The present investigation was planned to evaluate the effects of cinnamon oil as an alternative antibiotic growth promoter in broilers. A total 144 broiler chicks were randomly allocated six experimental groups, each consisted four replicates and replicate chicks. groups (I) basal diet; (II) diet + chlortetracycline @ 1 g/kg feed; (III) 400 mg/kg (IV) E. coli 1.0 mL (1.5×108 CFU/mL) orally on 1...

AIM This study was conducted with an aim of studying the efficacy of water supplements of Aloe vera and Azadirachta indica (neem) during pre-starter age (0-2 weeks) on gut health and histomorphometry in Vanaraja chicks. MATERIALS AND METHODS A total of 192 day old Vanaraja chicks were randomly assigned to one of four herbal water treatments throughout the experimental pre-starter stage (0-2 w...

The Fusarium mycotoxin enniatin B (ENN B) is a so-called emerging mycotoxin frequently contaminating poultry feed. To investigate the impact of chronic ENN B exposure on animal health, broiler chickens were fed either a diet naturally contaminated with ENN B (2352 µg/kg) or a control diet (135 µg/kg) for 2, 7, 14, or 21 days. ENN B concentrations were determined in plasma and liver using a vali...

The current study investigated the efficacy of a probiotic mixture on ameliorating heat stress-induced impairment of intestinal microflora, morphology, and barrier integrity in broilers. The probiotic mixture contained Bacillus licheniformis, Bacillus subtilis, and Lactobacillus plantarum. Three hundred sixty 21-d-old Ross 308 male broilers were allocated in 4 experimental treatments, each of w...

This study investigated the protective effect of β-1,3/1,6-glucan on gut morphology, intestinal epithelial tight junctions, and bacterial translocation of broiler chickens challenged with Salmonella enterica serovar Typhimurium. Ninety Salmonella-free Arbor Acre male broiler chickens were randomly divided into 3 groups: negative control group (NC), Salmonella Typhimurium-infected positive group...

This experiment investigated the effects of different doses of Bacillus subtilis spore as a probiotic on the immune response, intestinal morphology and ileal dry matter digestibility in broiler chicks exposed to stress induced by corticosterone (CORT). Two hundred and eighty-eight one-day-old Ross 308 male broiler chicks were randomly assigned to six treatments in a <e...

This meta-analysis aimed to evaluate the effects of dietary supplementation with essential oils (EOs) on egg production and quality, antioxidant status in blood serum, intestinal morphology laying hens. The data used were obtained from 38 peer-reviewed publications. effect size was evaluated by weighted mean differences (WMD) between experimental treatments (diets added EOs) control without EOs...

The present study was carried out to determine the effects of the inclusion of a spore-forming probiotic (Bacillus subtilis) in laying Japanese quail diets as an alternative to growth-promoting antibiotics to help produce healthy eggs and meat. This experiment was conducted as a completely randomized design with three treatments (control, 0.05% bacitracin methylene disalicylate (BMD), or 0.1% B...
