A female mallard duck incubates her eggs. Egg incubation is the process by which an egg, of oviparous (egg-laying) animals, develops an embryo within the egg, after the egg's formation and ovipositional release. Egg incubation is done under favorable environmental conditions, possibly by brooding and hatching the egg.
An incubator is a device simulating avian incubation by keeping eggs warm at a particular temperature range and in the correct humidity with a turning mechanism to hatch them. The common names of the incubator in other terms include breeding / hatching machines or hatchers , setters , and egg breeding / equipment .
By January 2020, In Ovo was capable of sexing 1,500 eggs an hour (0.42 per second), but the Dutch poultry sector required 40,000 eggs an hour, so further innovation was necessary. [36] In Ovo received millions of euros in research investments, mostly from German chemicals company Evonik, Singaporese venture capital company Visvires New Protein ...
However, the rate of development can be affected by a range of factors; including the specific breed, the temperature of incubation, the delay between laying and incubation, and the time of year, raising the need to create a standardised system based on morphology rather than chronological age.
Several technologies may obviate chick culling by determining the sex of a chick before hatching. Some of these technologies rely on measuring eggs (through spectroscopy, chemical assays, or imaging); they can determine a chick's sex within 3-13 days of incubation. [52] [53] Some methods require genetic engineering to make male eggs fluorescent ...
From aiding in hatching chicken eggs to enabling scientists to understand and develop vaccines for deadly viruses, the laboratory incubator has seen numerous applications over the years it has been in use. The incubator has also provided a foundation for medical advances and experimental work in cellular and molecular biology.
Broodiness is the action or behavioral tendency to sit on a clutch of eggs to incubate them, often requiring the non-expression of many other behaviors including feeding and drinking. [1] Being broody has been defined as "Being in a state of readiness to brood eggs that is characterized by cessation of laying and by marked changes in behavior ...
The chicken embryo is a unique model that overcomes many limitations to studying the biology of cancer in vivo. The chorioallantoic membrane (CAM), a well-vascularized extra-embryonic tissue located underneath the eggshell, has a successful history as a biological platform for the molecular analysis of cancer including viral oncogenesis, [8] carcinogenesis, [9] tumor xenografting, [1] [10] [11 ...
