Hatching - Incubation

Hatching of eggs refers to the production of baby chicks. In early days eggs were hatched by placing them under broody hens. Desi hens proved to be ideal for this purpose. Only 10 to 12 eggs can be put under 1 hen. This method of hatching is highly unsatisfactory for large-scale production of baby chicks. Incubators, which provide similar environment as that of broody hens, but more efficiently, are used at present for hatching of eggs. The incubation period for chicken eggs is 20 to 21 days, and increases up to 30 days for other poultry. After sitting for some days, a broody hen can be given some newly hatched chicks and, if they are accepted, the original eggs can be removed and replaced with more chicks. Thus hens with a better record of mothering can be better utilised for their abilities. Eggs initially need a very controlled heat input to maintain the optimum temperature of 38°C, because the embryo is microscopic in size.

Introduction Given the fact that the poultry industry has been a main contributor to the U.S. food supply over the past two decades, with an increase from $44.4 billion in value of production in 2013 to $48.3 billion in 2014, the necessity of capitalizing on the production of poultry is evident (1, 2). With the increasing trend to systematically remove sub-therapeutic levels of antibiotics from poultry feed due to public demand, poultry producers have been facing new challenges...

Introduction Environmental conditions influence metabolic and developmental processes during the perinatal period of mammals and avian species [1,2,3]. Changes in metabolism and development in this period can have long-term effects in later life [2,4]. Particularly glucose metabolism seems to play a crucial role in survival and early development of animals [1,5,6]. In...

INTRODUCTION In Egyptian governorates, the poor storage conditions of market-egg at room temperature especially in summer leads to higher economic losses for producers. Therefore, it is very important to evaluate the egg quality characteristics as well as factors affecting them up to arrive to the consumer in the best condition. The park yard system of the egg production sustains the small families’ economics and...

The greatest challenge for modern hatchery is to achieve uniform, high vitality flocks of day old chicks. Next to incubation technology, good hatchery management can greatly influence this. Uniformity is an important issue for a hatchery, and the use of good hatchery management practices can make a valuable and lasting contribution, from the hatchery right through to farm level . ...

A common management tool in the handling of hatching eggs is treatment of the eggs with a fumigant or other type of disinfectant to reduce the number of microorganisms on the shell surface. In addition, sanitation of the hatchery building, hatchery equipment, egg transportation equipment, etc., is critical to good hatchability and high quality hatchlings. Penetration of the hatching egg shell by microorganisms results in embryonic mortality, weak chicks, high chick mortality, and poor...

Multi stage and single stage incubation systems use similar equipment but are operated quite differently except that they both turn the embryos much the same.  Multi-stage incubation systems must provide for the average needs of all embryos within the incubator, thus it may not meet the specific needs of the youngest and oldest embryos at the same time in the incubator.    Single stage incubation systems...

1. Introduction Growth rates of broiler chickens have increased and production cycle times have decreased by 60% in the last 40 years. This is widely agreed to be the direct result of genetic selection and improvements in poultry nutrition (Havenstein et al., 2003a). The incubation and brooding period has become a larger part of the total life span of the broiler chicken. This is expected to increase even more...

When a problem occurs in hatchability, usually it can be categorized as a hatchery, egg handling, or breeder flock problem. If the problem has originated within the breeder flock, it is probable that it happened at least 4 weeks earlier, assuming 3 weeks of incubation and 1 week of egg storage. This delay in identifying a problem is costly and may even make it impossible to determine the cause if the effect is of short duration. It is necessary to identify the problem as early as possible,...

I was told that the hatchability for the first 7 days may remain the same as of day one but would decrease @ 1% per day after that. I am of the opinion that it may drop by 1% per week of holding. Has some one done study on this and can you enlighten me. What i am looking for is an answer to say if I hold for 7 days what is the hatch % loss, for 14 days what is the loss and 21 days what is the loss etc. ...
