About this Research Topic
The fat deposition is closely related to the efficiency of production, carcass/meat quality, reproductive performance, and health condition in poultry. Fat can be deposited at different sites of the body: around abdominal tissues (visceral fat or central fat), under the skin (subcutaneous fat), and in the muscle (intramuscular fat, IMF). IMF is known as popular fat because it is one of the determinants of meat quality, whereas extra abdominal fat is unpopular as it denotes high cost in production. The metabolism disorders of body fat usually relate to chronic diseases. Both genetic factors and nutritional strategies have been shown to influence body fat metabolism.
This Research Topic will focus on the physiological, biochemical and molecular regulatory mechanism of lipid metabolism (lipogenesis, lipolysis, fatty acid biosynthesis and oxidation), and the effects of lipid on growth and development, reproduction and health in poultry. Subject areas will include molecular biology, physiology, breeding, genetics, nutrition, and reproduction. Studies with high-throughput technologies are encouraged, including genome, metabolome, epigenome, metagenome, etc.
We welcome Mini-Reviews, full-length Reviews, and Original Research. Our Research Topic include, but is not necessarily limited to:
• The mechanism and regulation of poultry fat deposition at the adipocyte or adipose tissue level.
• The mechanism and regulation of lipid metabolism with diverse genetic resources.
• The mechanism and regulation of lipid metabolism with different nutritional strategies or environmental conditions.
• The mechanism and regulation of lipid metabolism with interdisciplinary strategies, eg. nutrigenetics, nutrigenomics, metagenomics, etc.
Keywords: poultry, lipid metabolism, biochemical mechanism, molecular regulation, genetic basis
