“…Our previous studies, using the same incubation temperature treatments as this study, have found that ducklings incubated at the lowest temperature have reduced physiological performance relative to ducklings incubated at the higher temperatures (Hepp et al 2006;DuRant et al 2010DuRant et al , 2011Hopkins et al 2011;S.

The University of Chicago Press ABSTRACTRecent research in birds has demonstrated that incubation temperature influences a suite of traits important for hatchling development and survival. We explored a possible mechanism for the effects on hatchling quality by determining whether incubation temperature influences embryonic energy expenditure of wood ducks (Aix sponsa). Because avian embryos are ectothermic, we hypothesized that eggs incubated at higher temperatures would have greater energy expenditure at any given day of incubation. However, because eggs incubated at lower temperatures take longer to hatch than embryos incubated at higher temperatures, we hypothesized that the former would expend more energy during incubation. We incubated eggs at three temperatures (35.0Њ, 35.9Њ, and 37.0ЊC) that fall within the range of temperatures of naturally incubated wood duck nests. We then measured the respiration of embryos every 3 d during incubation, immediately after ducks externally pipped, and immediately after hatching. As predicted, embryos incubated at the highest temperature had the highest metabolic rates on most days of incubation, and they exhibited faster rates of development. Yet, because of greater energy expended during the hatching process, embryos incubated at the lowest temperature expended 20%-37% more energy during incubation than did embryos incubated at the higher temperatures. Slower developmental rates and greater embryonic energy expenditure of embryos incubated at the lowest temperature could contribute to their poor physiological performance as ducklings compared with ducklings that hatch from eggs incubated at higher temperatures.

“…Therefore, slight deviations above the recommended incubation temperatures are more detrimental to inovo development than similar deviations below those temperatures. High incubation temperatures have negative impacts on chick heart weight (Wineland et al, 2000;Leksrisompong et al, 2007;Lourens et al, 2007), on bone development (Oviedo-Rondon et al, 2009a, b;van der Pool et al, 2014), and on the immune system (DuRant et al, 2012), predisposing chicks to ascites, leg problems, and immune deficiencies, respectively.…”

Due to its central position in the production chain, in-ovo development is influenced by pre-incubation factors that affect the quality of embryonated eggs and incubation conditions themselves, and both may influence egg hatchability and chick quality, as well as bird survival, growth performance, and phenotype in the field. The evolution of the incubation process over the years is characterized by significant scientific and technological development. Presently, the main current focuses of research are the manipulation of thermal incubation conditions, eggshell temperature, and the integrated effects of factors that influence incubation. In this context, one of the questions that needs to be asked is how effective are the current physical conditions of incubation to promote greater hatchability and better quality chicks, and higher survival and better performance in the field under adverse conditions or not. What are the new and future prospects for incubation? The purpose of this paper was to review the role of the physical agents of incubation, such as temperature, relative humidity, O 2 and CO 2 concentration, and egg turning and position from an integrated perspective, considering egg incubation as the transitional link between egg and poultry production.

“…For example, in captive mice, several studies have shown wound healing to be a highly heritable trait (McBrearty et al, 1998;Li et al, 2001). Alternatively, DuRant et al (DuRant et al, 2012) demonstrated that the environment can also contribute to immunity independent of genetic contributions: ducklings incubated at sub-optimal temperatures showed a 19-21% decreased swelling response after injection with phytohaemagglutinin. Therefore, we recommend future studies be directed at understanding the relative contribution of parental and environmental factors on offspring immunity.…”

SUMMARYImmune function early in life can be influenced by parental effects and the environment, but it remains unclear how these two factors may interact to influence immunocompetence. We evaluated maternal and environmental contributions to offspring healing ability in a viviparous reptile, the northern watersnake (Nerodia sipedon). We measured wound healing rates, a highly integrative and biologically relevant measure of innate immunity, of females and their offspring collected from sites contaminated with a toxic heavy metal and compared them with those of individuals from reference sites. We found that female watersnakes that healed the fastest produced offspring that also exhibited faster healing rates. However, we detected no influence of environmental pollution on maternal or offspring healing rates. To our knowledge, our study is the first to correlate maternal and offspring wound healing ability in a wild vertebrate.
