the main objective of this study was to elucidate the effect of short- term exposure of japanese quail eggs to acute high incubation temperature on embryonic development and on the ability of post- hatched chicks to cope with subsequent heat stress conditions during the growing period. a total of 998 japanese quail eggs were divided into two groups, the first group (470 eggs) was maintained at ...

there are little information about growth properties of low pathogenic (lp) avian influenza virus (aiv) in embryonated chicken eggs (eces) at different incubation temperatures. knowledge of this information increases the quantity and quality of antigen in vaccine production process. for this purpose, 10-5 dilution of aiv (a/chicken/iran/99/h9n2) was inoculated (intra-allantoic) into 400, 11-day...

The study of warming impact on soils requires a realistic and accurate representation temperature. In laboratory incubation studies, widely adopted method has been to render constant temperatures in multiple chambers, via comparisons soil responses between low- high-temperature derive the changes. However, this commonly used failed imitate both magnitude amplitude actual as observed field condi...
