About this Research Topic
Nutrigenomics is one of the most rapidly developing scientific fields that holds great promise for improving the health and performance of food-producing animals. Nutrigenomics begins a new era of working with nutrition and genetics, and gives us an insight into how nutrients interfere with an organism’s genetics and the resulting phentotypic response. It focuses on elucidating the effect of dietary nutrients on expression patterns of different genes and epigenetic modifications, such as DNA methylation and histone modifications. Nutritional programming during prenatal and postnatal life may have long-lasting consequences on the growth and health of birds and animals. Particularly during prenatal life, nutrients not only influence the developing embryo, but also affect the primary germ cells responsible for the next generation. Therefore, exploring the effect of nutrients on genomic functions holds great promise to enhance the production performance and health of food animals.
Elucidation of epigenetic modifications controlled by nutrients is required to better understand the diet-gene interactions in avian species. Therefore, comprehensive studies are required to provide mechanistic insights into the nutritional regulation of gene expression through DNA methylation, histone modifications, and noncoding RNA interactions. Recent advances in high throughput techniques, such as whole-genome bisulfite sequencing, chromatin immunoprecipitation sequencing, and global RNA-Sequencing, must be utilized for nutrigenomic studies in avian species.
In this Research Topic, we aim to highlight recent advances in nutritional and nutrigenomic interventions focused on improving health and performance, including the development of new methods/protocols and studies which focus on the discovery of diet-gene interactions in avian species.
We particulary welcome Reviews and Original Research articles on the following aspects:
1. Scope of nutrigenomics for enhancing the production and reproduction performances in different avian species
2. Novel interventions involving nutrigenomics and nutrigenetics in poultry nutrition
3. Nutritional interventions to improve gut physiology to enhance nutrient efficiency, performance, and health of birds
4. Phytogenic feed additives having nutraceutical potential to reduce the use of infeed antibiotics in birds
5. Potential modulation of the gut microbiome and immunity-related factors in birds to address health challenges and product quality and safety
6. Interplay of nutrition and genomics to mediate the climatic stress under the climate change scenario
