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.
Each year many people enjoy ordering chicks from a hatchery or purchasing young chicks from a feed store. These chicks are raised primarily for home laying flocks. Some of these chickens are raised for the family table, while others are kept mainly as pets. Whatever purpose the adult chickens serve, special care must be given to young chicks in order for them to survive and grow into healthy adults. Care of Chicks Chicks, or...

Introduction Achieving the best fertility is the only goal for successful running of any breeder operation. Advanced genetic selection in broiler breeding has led to tremendous improvements in progeny performance. Body weight gain achievement in modern broiler breeders is swifter than the past hence male management is a crucial aspect to obtain good quality and quantity of semen. Due to some unforeseen events if there is heavy mortality in males, maintaining the fertility...

The poultry industry, as a whole, is comprised of many segments, each with varied levels of importance. Each of these segments must be closely managed and controlled in order to maintain any gains and improvements made in other areas of the entire poultry operation. For example, it is well known that most hatchability problems are a result of poor fertility. However, when egg production is attained and the flock maintains high levels of fertility, how we care for...

INTRODUCTION Cool temperature storage of eggs prior to incubation is a frequent practice of commercial broiler hatcheries. However, continued storage beyond 7 d leads to an increase in early embryonic mortality. The cellular and molecular mechanisms responsible for early embryonic mortality associated with egg storage and means to reduce such mortality has been addressed by several investigators (Fasenko, 2007; Hamidu et al., 2011; Dymond et al., 2013)....

In some companies, fertility and hatchability start to decrease during the last weeks of production, for example after 50 weeks, at the same time there is a loss of feathers in the back or there is an overweight of the egg. How can we improve fertility and hatchability in the last phase of production of broiler breeders? To improve fertility and hatchability we must evaluate three important points: (a) management of the roosters, (b) hen feather cover and (c) egg size. ...

A patented split-feeding program for broiler breeders is disrupting conventional approaches to poultry nutrition. Developed by Trouw Nutrition, a Nutreco company, the split-feeding innovation has demonstrated improved hatching rates and lower feed costs in research centre trials and commercial farm studies.
The system delivers nutrients that support the birds’ requirements for egg formation at different times of day, as research conducted with laying hens shows birds’...

INTRODUCTION Broiler hatching eggs can be stored at temperatures lower than ambient temperature before incubation, which is a common practice in commercial breeding farms and hatcheries. As per the variable market demand for 1-day-old parent stock chicks and the hatchery capacity, the duration of egg storage varies. Normally, commercial hatcheries set their eggs after 3 to 5 d of storage to minimize the negative effects of...

INTRODUCTION There has always been a natural biological variation in the time that commercial broiler chicks emerged from their egg shells (hatch time) even under optimum conditions of artificial incubation. Thus, early hatching chicks have generally remained in the hatcher longer while awaiting removal of later hatching chicks from the machine (pull time) (Elibol et al., 2011; Powell et al., 2016). It has been reported that performance after placement was negatively associated...

Introduction To achieve good hatchability and chick quality, fertile eggs need careful management from the time they are laid. Environmental conditions during egg collection, egg shell disinfection, transport, pre-storage incubation, storage, pre-warming or during incubation are all important. Inappropriate treatment can result in depressed hatchability, change the pattern of embryo mortality and may also affect post-hatching performance. The investigative procedures can be used...

1. INTRODUCTION The increasing demand for poultry products and the associated cost of feed and energy along with the economic downturn has encouraged the commercial poultry industry to become more efficient and economical. Currently hatching eggs (HE) are stored between 1-3 days prior to setting, which ensures that the incubator will be filled to capacity. This procedure produces a large hatch quantity in a shorter time with decreased associated costs. There had been several...

Due to dynamic market demands for day old chicks and the large scale of commercial hatcheries, the storage of hatching eggs is often unavoidable. Although the detrimental effects on hatchability and chick quality have been known for a long time, hatchery managers aim for an optimal utilisation of the considerable capacity of modern incubators and to minimise transports from farm to hatchery. In this way, efficiency is optimised and costs are reduced. Even though...

Brooding is the most crucial, critical and decisive period in a breeder chick’s life. Especially the first two weeks. This period has a great impact on future performance of the flock. More than 50% is decided in this period as to how a flock performs for the rest of its life. Mistakes made during this period cannot be corrected later on. If this period is managed correctly, the genetic potential of the bird, in terms of hatching eggs, fertility, hatchability and maximum saleable day old chicks...
