Poultry genetics and reproduction
Poultry breeding has been one of the most impactful advances in the last 100 years. The role that improved global production of eggs and poultry meat have in reducing global hunger and food insecurity is difficult to overstate. The vast majority of these improvements have come from genetic selection for improved feed efficiency, along with streamlining of the overall production system, and better understanding of poultry nutrition. While the industrial approach to poultry production has created a highly consistent and dependable food source the world over, several problems threaten the long term sustainability of this model - including musculoskeletal and metabolic disorders, welfare concerns, and the need to adapt to a changing climate. Researchers in poultry breeding and genetics utilize quantitative, population, and molecular genetic techniques to help understand the effects of selection for economically important traits and enhance genetic performance through changes in environment and management strategies.
In all avian species, as well as in other animals in the animal kingdom, increasing age has an adverse effect on reproductive success. The age related decrease in reproduction in the commercial fowl is due, in part, to a decline in egg production, fertility and hatch of fertile. This decline in egg production begins to occur once hens reach their peak in egg production. However, the precise factors that influence and cause the age related decline in reproduction are poorly...

Chickens, like most animals, typically produce equal numbers of males and females. But this natural sex ratio doesn't always work in the poultry industry's economic favor. A University of Georgia researcher is working on ways to skew the chicken's sex ratio to help the industry streamline production and make more money.
Chickens are big business in Georgia, worth $4.9 bln in 2008, or 41% of the state's total agricultural value. For the...

There are many breeds of chickens, all developed for various purposes. The reason a person wishes to have chickens will determine the breed and/or type of chicken to select. Chickens predominantly used for the production of meat and/or eggs comprise the majority of all chickens raised. However, some breeds are bred specifically for ornamental and/or show purposes. The breeds used for production purposes can be classified into three basic types of chickens;...

Detailed information describing the categorization and incidence of embryo malpositions and deformities in commercial poultry is not readily available. Additionally, there is often little consistency in these data among hatcheries. Any decrease in the number of usable chicks may result in substantial economic loss to poultry integrations. In a typical hatch, it is common to lose about 1-2% of the chicks due to deformities and malpositions. Deformities manifest...

The vast majority of poultry growers use unvented heating units, i.e. brooders or space furnaces, to heat their poultry houses, using propane or natural gas as fuel sources. Record high propane/natural gas prices over the last two years have led a number of producers to explore the possibility of using biomass furnaces to provide heat in their poultry houses. A number of alternative heating systems exist with a price range of less than $10,000 to over $60,000 (Czarick, et al., 2008)....

Fertilization in commercial chickens is usually the result of natural mating. However, in some cases, artificial insemination is commonly practiced. The turkey industry especially depends on artificial insemination since natural mating is virtually impossible as a result of intense genetic selection for conformation and body weight.
The completed mating in chickens is the culmination of a sequence of behaviors. The rooster will initiate mating by exhibiting courtship behavior:...

Chick quality is still a term than many breeder, hatchery and broiler people still have a hard time defining. Most everyone can identify poor quality chicks from good quality chicks. However, when three people are asked to define chick quality, three different descriptions would be received. Currently chick quality is mainly based on observations such as whether or not the chick is alert, dry or wet, whether the navel is completed sealed, and deformities. While these are a good start, there...

What are the important factors in rearing productive broiler breeders? The time spent preparing for the new flock and the first seven to ten days after placement are the most critical time to promote the success of the flock. It is difficult with the lag in time between the rearing phase and the end of lay to pinpoint problems in rearing management that affected flock performance, but there is a direct relationship between the start the chicks get and how they perform during the lay cycle....

The main purpose of the avian egg is to produce a viable, healthy chick. Embryogenesis is dependent on several factors that are referred to as the four basic principles of incubation. These include temperature, humidity, ventilation and mechanical agitation (egg turning). Light and sound have been implicated as environmental elements that affect embryo development, but do not have enough influence to be incorporated as major components of a commercial hatching program. Both of these factors...

Flock fertility is dependent on the reproductive status of the birds (level of egg and semen production) combine with the bird’s interest and capability of mating. Fertility usually increases from a low of 65-75% at the start of lay (23-24 weeks of age) and peaks at 95-98% at 35-37 weeks of age. Between 40-45 weeks of age fertility declines and the older the birds get the faster the decline in fertility. What are the reasons for this decline? After 40 weeks of age the breeder hen needs more...

Geese are raised in small flocks in all parts of Georgia as a hobby, for pleasure, for exhibition and sometimes for profit. They are a popular bird for many small flock owners as they are very hardy and not susceptible to many of the common poultry diseases. They are excellent foragers and can be raised on good pastures or lawns as early as the first week. Reproducing geese is not difficult, but requires some attention to management to get the most success from flocks. Geese generally...
