Dose-dependent positive effects on hatchability and hatchling weight have been attributed to ascorbic acid (AA) when eggs were submitted or not to intermittent heat stress during incubation. Fertile breeder (Cobb (R)) eggs ...

Skin and feather characteristics, which play a critical role in body temperature maintenance, can be affected by incubation circumstances, such as incubation temperature. However, no study to date has assessed the influence ...

In a thermal gradient the preferred ambient temperature (T (a) pref) of chicken hatchlings is a few degrees lower than thermoneutrality. To investigate whether a correlation may exist between T (a) pref and the autonomic ...

Broilers are known as an efficient source of lean meat. Genetic selection resulted in broiler strains with large body size and fast growth, but a concomitant increase in fat deposition also occurred. Other than reducing ...

Studies describing and identifying mycobiota affecting the eggs of wild reptiles are rare, despite the potential importance of mycoses for the survival and performance of individuals and populations. The aim of this study ...

Captive crocodilians reduce their intake of food during cold periods, even when kept under controlled conditions and fed ad libitum. These manifestations may be due to photoperiod length which is known to influence circadian ...
