Dear Colleagues,

Poultry species are very important for providing meat and eggs to human and their productions have been dramatically increased worldwide. Since the poultry species were domesticated, humans give lots of efforts for selection and breeding of the poultry species, mostly for the production traits, such as body weight and egg production. Recently, there are still lots of traits, which need to be improved including biochemical compounds and egg/meat quality traits. Also, new investigation is ultimately needed for the native poultry breeds, indicating their use of further breeding program including disease resistance traits. Therefore, the performance traits covering in the special issue are very diverse from the conventional productions traits to new traits affecting the poultry production.

Since the publication of the chicken genome in 2004, Researches, using the developed technology, of the Poultry Genetics and Genomics have been also dramatically improved. However, there are numerous poultry production traits with an unknown genetic background. With the high-throughput genetic and genomic techniques available today, the research community has the possibility to also unravel the complex production traits for the poultry. Therefore, This Special Issue in “Animals” will highlight the improvements of performance traits in poultry using cutting-edge of genetics and genomics technology. This Issue also will provide an overview of recent developments in this field of research, including perspectives on current and upcoming challenges. In this Special Issue, original research articles and reviews are welcome.

I look forward to receiving your contributions.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Animals is an international peer-reviewed open access semimonthly journal published by MDPI.
