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.
INTRODUCTION If we consider that the most research studies and debates are directed to big exploitations and producers in poultry industry (both eggs and meat production), who have the financial possibilities to employ specialists and who have a wide variety of poultry tools and equipments, then we may say that the middle and small producers are kind of deprived of accessing high technologies in this field. Lack of money, the...

Introduction
Lately, quail growing has awaken a great interest amongst producers, companies and researchers, due to the fact that it requires less labor and investment than other livestock activities, as well as because of the productive qualities of quails. During the last decade, the nutritional habits of the population have changed. Restaurants and " churrasquerias" (Brazilian typical...

"New developments in genomics have provided opportunities to enhance breeding programs in poultry by being able to genotype large numbers of individuals for tens of thousands of genetic markers across the genome at a reasonable cost," remarked Dr. Jack Dekkers of Iowa State University. He presented to breeder specialists and geneticists at the recent 2011 National Breeders Roundtable, sponsored by the Poultry Breeders of America and U.S. Poultry & Egg...

I have noticed continuous prolapse in a flock of broiler breeders aged 12th wk now.It is happening since lat 8 weeks and so for more than 1% mortality has occured. We checked the dietary salt level and it is ok.We have ruled out chronic coccidiosis.The flock is on natural light only. Please help. ...

Many broiler breeders have been reared since we first began to explore the idea that something other than just body weight (BW) and uniformity, both important longstanding management paradigms, was involved in proper rearing of broiler parent stock. Our original work was released in 1995 under the umbrella that we called the ‘concept of minimum cumulative nutrition’ that emphasized the form of the feeding program, long-term relative consistency of feeding, and coordination of age at...

Effect of yeast extract on early intestinal tract development of broilers

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:...
