The effects of organic and inorganic sources and concentration (0 and 0.3 mg per kg of diet) of Selenium (Se) on growth performance, blood biochemical and immune system were evaluated in broiler chickens. Chickens were fed corn-soy-based diets formulated to 8 dietary treatments containing no added Se (negative control), negative control plus yeast (positive control), and 6 diets had 0.3 mg/kg o...

BACKGROUND: Salmonella Enteritidis (SE) infection in poultry is one of the most important concerns in poultry. Virulence and pathogenicity of the SE isolates from Iran have not been well studied so far. OBJECTIVES: In the present study, three Salmonella Enteritidis (SE) isolates were compared with a standard SE strain (PT21) for virulenc...

the safe and effective management of radioactive waste has been given utmost importance from the very inception of nuclear industry in india and it covers the entire range of activities from handling, treatment, conditioning, transport, storage and finally disposal. radioactive waste is generated at various stages of the nuclear fuel cycle, which includes the mining and milling of uranium ore, ...

the study of tectonic evolution of the tethyan and se asian regions indicates that these tworegions have each passed through southwardly progressing sequences of similar tectonic events. both regionshave experienced a southward island-arc subduction and back-arc spreading leading to continentaldetachment from gondwanaland, with an earlier southward island arc subduction of palaeotethys (tethyan...

an experiment was carried out to evaluate and compare the effects of organic and inorganic selenium (se) sources on broiler male birds (ross 308). uniform broiler male chicks divided in to five groups with six replicates were fed with either normal feed (without supplemental se, negative control), 0.25 ppm of inorganic se, 0.5 ppm of inorganic se, 0.25 ppm of inorganic se + 0.25 ppm of organic ...

In the southeast of bam, there is a collection of volcanic rocks with andesite, basalt and trachy andesite composition. The texture of these rocks are often porphyritic with microlithic, porphyric cavity, and sometimes glomerulophorphuri, sore throat trachytic. Main minerals include Olivine, Clinopyroxene, Plagioclase and secondary minerals including opaque minerals, Iodenzyte, secondary Biotit...
