Broiler surface temperature distribution of 42 day old chickens
Broiler chickens in Brazil are generally reared from 1 to 42 days when they are exposed to procedures such as fasting, harvesting, crating and transport to slaughter. Maintaining homeostasis is of great importance for broiler survival under harsh environment especially prior to slaughter. Heat loss varies in the distinct parts of the body during the growth period, and it is related to the air t...
متن کاملHistopathological Study of A/chicken/iran/772/99 (h9n2) Influenza Virus in Commercial Broiler Chickens
Avian influenza outbreaks in 1998 due to H9N2 subtype of avian influenza virus (AIV) that occurred in poultry industry in Iran caused serious economic losses. The aim of this study was to investigate the pathogenesis, clinical signs, gross and histopathological findings of the chickens experimentally inoculated with A/Chicken/Iran/772/99(H9N2) influenza virus, isolated from the commercial broil...
متن کاملCaprylic acid supplemented in feed reduces enteric Campylobacter jejuni colonization in ten-day-old broiler chickens.
Campylobacter is one of the leading causes of human foodborne illness in the United States, and epidemiological evidence indicates that poultry and poultry products are a significant source of human Campylobacter infections. Reducing Campylobacter in the intestinal tract would reduce contamination of poultry products and eggs. Caprylic acid, an 8-carbon medium-chain fatty acid has been shown to...
متن کاملEffects of Zinc Oxide Nanoparticles Supplementation on Mortality due to Ascites and Performance Growth in Broiler Chickens
Six hundred 1-d old male broilers (Ross 308) were assigned into four experimental groups; each was composed of 5replications of 30 birds including control (0), 10, 20 and 40 mg/kg nano-ZnO in the basal diets. Birds were exposed to low ambient temperature (15 to 18 ˚C) to induce ascites. Blood parameters including; activity of aspartate transferase (AST), alanine transferase (ALT), lactate dehyd...
