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
The basis of the modern poultry meat industry dates back to the late 1950s and nowadays, poultry meat is one of the most important protein sources in human diet. Global poultry meat production in 2000 was 69 million tons and this has been increased to over 97 million tons in 2010 (Windhorst, 2011): an annual production of approximately 70 billion broilers originating from approximately 600 million broiler breeders. These data underline how a relatively...

Introduction The neonatal period is a time when the chick requires special management and nutrition Provide good environmental and nutritional conditions for day-old chicks are crucial for obtaining the full performance potential of the chicks later in life and maintaining profitable business for producers. The neonatal chicks remain approximately 24-48 h without feed and water after removal from the hatchery until placement in the farm. This gap between...

Bacillus subtilis C-3102 spores are receiving increased attention as dietary direct-fed microbial (probiotic) performance enhancers for laying hens and breeders because as a feed supplement they typically are effective for improving egg shell thickness and brown egg shell color (in brown-egg strains), have high survivability through steam pelleting, and are economical (B.s. C-3102; CALSPORIN®, Calpis Co. Ltd, Tokyo, Japan). This specific strain of beneficial microorganism was...

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...

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,...
