Modeling incubation temperature: the effects of incubator design, embryonic development, and egg size.
A simple model to describe the relationship between the temperature of the developing embryo, incubator temperature, embryo heat production, and thermal conductivity of the egg and surrounding air is presented. During early incubation, embryo temperature is slightly lower than incubator temperature because of evaporative cooling. However, from midincubation onwards, metabolic heat production fr...
متن کاملEffects of Divergent Selection and Egg Status in Artificial Incubator on Reproductive Trait in Japanese Quail
Submitted: Jan 2, 2013; Accepted: Feb 6, 2013; Published: Aug 18, 2013 Abstract: This study was undertaken to determine the effects of divergent selection and different positions of Japanese quail eggs in artificial incubation on hatchability, egg weight loss, chick weight. 300 Japanese quail (100 birds in each line) were used for egg collection. These lines have been selected for high (HW) and...
متن کاملEffect of egg weight and position relative to incubator fan on broiler hatchability and chick quality.
Two experiments, which included 3 incubators, were carried out to investigate the effects of egg weight and position relative to incubator (setter) fan on embryonic mortality, second quality chicks, and fertile hatchability of broiler eggs. Three egg weight groups termed small (approximately 62.4 g), average (approximately 65.4 g), and large (approximately 68.9 g) were set in either the incubat...
متن کاملPorto Digital Incubator
The Brazilian incubation movement, despite having grown 25 percent in the last ten years, is going through a phase of stagnation due to lack of harmony between their structures and services to the new demands of society and the economic moment. Due to this fact, the Porto Digital Management Unit (NGPD), the institution responsible for the Porto Digital Technology Park governance in Recife – Bra...
متن کاملIncubator firm failure or graduation ?
9 One of the theoretically important factors for incubator firm performance is the strength of their linkages to the research university sponsoring the technology incubator. Herein, we focus on two types of university linkages to the sponsoring institution: a license obtained from the university and a link to university faculty, while controlling for incubator firm linkages to nonsponsoring res...
