Incubation Temperature Affects Body Size, Energy Reserves, and Sex of Hatchling Alligators
<p>I investigated the effects of incubation temperature, clutch, and sex on the morphometries, mass, and energy reserves of hatchling alligators. The effect of incubation temperature on hatchling genitalia was also studied. I evaluated and tested a method for determining the sex of hatchling …

Effect of incubation temperature and composition of brucella agar on growth of Campylobacter jejuni
Aerotolerance of Campylobacter jejuni ATCC 29428 and one of its aerotolerant mutants (strain MC711-01) was measured at 37°C and 42°C. The aerotolerance of C. jejuni was higher at 42°C than at 37°C. Three different lots of Gibco dehydrated Brucella broth were used to prepare Brucella agar. The agar …

INFLUENCE OF EMBRYONIC METABOLIC RATE AND INCUBATION TEMPERATURE ON INCUBATION LENGTH VARIATION IN NEOTROPICAL PASSERINES
… for example, does not explain variation in incubation periods among neotropical passerines. Incubation temperature can explain some variation in developmental periods, but substantial variation remains unexplained. Here we examine two previously untested alternatives. Adult metabolic rates …

Incubation temperature impacts growth, physiology and survival in nestlings of an open-cup nesting passerine
… Much less is known, however, about the role of incubation temperature in shaping the phenotype. Among species in which one or both parents incubate, there is the possibility that changes in incubation behavior on the part of the parent(s) can impact the developing offspring. The vast majority of …

Consequences of avian parental incubation behavior for within-clutch variance in incubation temperature and offspring behavioral phenotypes
… early developmental environment is through egg incubation. Not only is incubation necessary for hatching success, but small changes of <1C in average incubation temperature have large effects on post-hatch offspring morphology and physiology. However, incubation is energetically costly and …

Incubation temperature and post-hatch stress effects on immune parameters, immune system development, and performance in commercial broilers
… ability to respond to environmental challenges. Incubation temperature, post-hatch transportation, and vaccination may impose stress upon the embryo and post-hatch chick and impact immune system development and lifetime performance of the bird. The objective of the first study was to evaluate …

The role of incubation temperature in determining avian phenotype: implications for avian ecology, life history evolution, and conservation
… the wealth of research demonstrating that incubation temperature affects a suite of traits important to fitness in reptiles, we are only now discovering that nest temperatures are a defining component of the avian developmental environment. Aspects of the nest environment may be an …

The influence of embryo incubation temperature on later life aerobic performance of Lake Whitefish (Coregonus clupeaformis) and Yellow Perch (Perca flavescens)
Temperature represents one of the most influential abiotic factors affecting all living organisms. Ectotherms, including fish, can be affected by temperature at the cellular, individual, population, and community levels. In modern times, climate change and thermal pollution pose major threats as …

Effect of probiotics or high incubation temperature on gene expression and cell organization of the small intestine and yolk sac of chicks
… in young healthy chicks. Heat stress during incubation was shown to increase mortality and decrease hatchability of chicks, while no studies have investigated the effect of heat stress on the integrity of the YS, which might be related to hatching performance. There were four studies …

Effects of Incubation Temperature and Transportation Stress on Yolk Utilization, Small Intestine Development, and Post-Hatch Performance of High-Yield Broiler Chicks
… Stressors such as elevated or decreased temperatures during incubation and post-hatch transportation may have an effect on the gastrointestinal development of the broiler chick. The objective of the first study was to investigate the effects of elevated embryonic incubation temperature …

Effects of high incubation temperature on the developing small intestine and yolk sac of broiler chicks with insight into goblet cell development in the small intestine early posthatch
The incubation period is crucial for development and overall quality of a chick. The selection for fast growing broilers has allowed the birds to reach market weight at a faster rate making the incubation period a larger portion of a broiler's life. A faster growth rate can lead to the release of …

Influence of Incubation Conditions on Turkey Poult Intestinal Development and Susceptibility to Poult Enteritis
… susceptibility to poult enteritis complex (PEC). Temperature and hypoxic stress during embryonic incubation may impact organ growth and development, development of immunocompetency, post-hatch performance and may predispose poults to enteric disease. The objective of the first study was to provide …
