Relevance. Currently, the pathology of joints in broiler chickens remains relevant, especially when bird is actively growing and gaining weight. Despite many antibacterial drugs, results treatment do not always give a positive effect. This may be due to properties pathogens themselves, which have adapted resist antibiotics, including formation biofilms, limited penetration drug into site infect...

Grape seeds (GS) and grape skins (GK) are natural sources of polyphenols with featured antioxidant capacity. An experiment was conducted to investigate the effect these polyphenol in diets formulated contain same total extractable content on growth performance, protein digestibility, plasma meat ?- ?-tocopherol thigh oxidation broiler chickens. Five experimental were formulated: control, contro...

The uncontrolled use of antibacterial drugs resulted in a wide spread forms microorganisms resistant to them. resistance most bacteria one degree or another is observed relation almost all existing antibiotics, which led significant decrease the effectiveness their not only veterinary medicine but also medicine. Therefore, an important task service faces alternative drugs. Thus, development and...

1. St. Louis virus has been successfully transmitted in the laboratory by the following 9 species of mosquitoes from 3 genera: Culex tarsalis, Culex pipiens, Culex coronator, Aedes lateralis, Aedes taeniorhynchus, Aedes vexans, Aedes nigromaculis, Theobaldia incidens, and Theobaldia inornata. 2. Though transmission has not been demonstrated, survival of the virus for more than a few days was sh...

Chicken Egg Yolk antibodies (IgY) were raised in 24 week old white leg horn chickens against Streptococcus mitis (MTCC 2696). The chickens received Booster injections of increasing concentrations of antigen to raise the antibody level in egg yolk. The antibodies were purified from immunized chicken egg yolk by Poly ethylene Glycol (PEG) and Ammonium sulphate precipitation method and further pur...

A NAD-dependent isolate 46 (C-3) of Haemophilus paragallinarum, which was previously demonstrated to be of high virulence, was transformed to NAD independence using a plasmid isolated from a naturally occurring NAD-independent isolate of H. paragallinarum. The transformation was performed by two different methods and the identity of all of the isolates, before and after transformation was confi...

this experiment was conducted to evaluate the effects of supplemental l-arginine (arg) in reduced-protein diets on cardiopulmonary performance and intestinal morphology in the broilers reared at high altitude. a total of 156 day-old male broilers were randomly assigned to 3 treatments and 4 replicates of 13 chicks and reared up to 42 days of age. treatment groups were designed as a normal-prote...
