| ABSTRACT Salmonella enterica is responsible for alimentary toxic infections associated with the consumption of contaminated poultry products and the antimicrobial resistant patterns of Salmonella circulating in the Tolima region are currently unknown. To address this issue, both the phenotype and genotype antibiotic resistance patterns of 47 Salmonella isolated from raw chicken carcasses sold at the Ibague city were analyzed by the disc diffusion, microdilution and PCR assays. All 47 Salmonella isolates showed resistance to five or more antimicrobial agents. Resistance to Ampicillin (AMP), Amikacin (AMK), Gentamicin (GEN), Tobramycin (TOB), Cefazoline (CFZ), Cefoxitin (FOX), Nitrofurantoin (NIT), Trimethoprim-Sulfamethoxazole (SXT), Tetracycline (TET),... |

| ABSTRACT Feed costs are the main limiting factors in poultry industry and alternative sources of food and/or feed supplements to optimize the bird´s life cycle and to extend their production period need to be explored. This study evaluated morphometric parameters of the small intestine and gonadotropin transcript levels in Isa Brown laying hens supplemented with glutamine + glutamic acid (Aminogut®) during a second production cycle. Molting was induced and groups of 100 hens each, were supplemented with 0, 0.8, 1.6 or 2.4% Aminogut® in their diet. At the end of the experimental period, tissue sections from duodenum, jejunum and ileum were processed by the Hematoxylin-Eosin technique and samples from hypothalamus and hypophysis were collected for RT-PCR... |
