The aim of the present study was to investigate the possibility of improvingproductive performance and immunity of growing Japanese quailreared during summer in Egypt by supplementing the diets with organic zinc (Bioplex zinc) and prebiotic (mannan oligosaccharides). Diets were a basal diet or the basal diet supplemented with 20 mg Bioplex zinc (3.0 mg Zn) (Zn1), 40 mg Bioplex zinc (6.0 mg Zn) ...
a total of 528 day-old ross 308 male broilers were used to study the effect of antibiotic, probiotic, prebiotic and organic acid on performance, cecal coliform load and internal organs’ weight. the chickens were placed into 6 groups with 4 replicates and 22 chickens per pen. six dietary treatments included: 1) negative control as basal diet without any antibiotic growth promoter and coccidiosta...
Dried distiller’s grains (DG) produced from ethanol fermentations dosed with 0 (control), 2, or 20 mg/kg virginiamycin-based product or spiked with virginiamycin (VM) postfermentation were fed to cattle and effects on antimicrobial susceptibility, and prevalence of antimicrobial resistance genes in commensal bacteria was examined. Biological activity assays of DG (from each fermentation) indica...
this experiment was carried out to investigate the effects of supplementing two macroalgae Sargassum cristaefolium and Gracilaria pygmaea extracts in feed on some growth indices, hematology and blood constituents of juvenile rainbow trout (Onchorhynchus mykiss). Rainbow trout were randomly divided into four groups: a control group was fed with basal diet, and three treated groups fed with basal...
Considering the role of arginine in the prevention of ascites and the possibility of replacing this amino acid with Guanidinoacetic acid (GAA), in present study, the effects of different levels of GAA (0.5 and 1 g/kg diet) supplementation in low-protein diets on growth performance and ascites incidence in broiler chickens were investigated. Therefore, a total of 208 male broilers (Ross 308...
A total of 360 1-day-old broiler chicks were randomly assigned to 4 treatments with 5 replicate cages and 18 birds per cage for a 35-day trial investigate the effects supplementing Achyranthes Japonica Nakai (AJN) root extract in low crude protein (CP) diet on growth performance carcass traits. Experimental diets divided as standard CP content diet, (LCP) LCP supplemented 0.025 or 0.050% AJN ex...
Vancomycin-resistant enterococci (VRE) are an important cause of hospital-acquired infections and an emerging infectious disease. VRE infections were resistant to standard antibiotics until quinupristin/dalfopristin (QD), a streptogramin antibiotic, was approved in 1999 for the treatment of vancomycin-resistant Enterococcus faecium infections in people. After that decision, the practice of usin...
