Gastroenterology, nutrition and metabolism

Section edited by Dr. Hayley Henderson

The 'Gastroenterology, nutrition and metabolism' section encompasses the broader aspects of animal nutrition, including the processes of digestion, absorption, and metabolism of nutrients at all biological levels, ranging from the molecular, cellular, tissue and organ level to clinical studies. The section welcomes submissions discussing the provision and ingestion of food vital to development, growth and overall health. As the digestive tract is considered to be one of the most important immune organs and adipose tissue is the biggest endocrine organ, manuscripts that focus on the relationship between immunology and endocrinology are especially welcome. Studies that advance our understanding of the nutritional status of animals and the role of nutrition in the onset of disease are also encouraged. Comparative nutrition and nutritional studies relevant to all domestic and nondomestic species will be considered, including ruminants, equids, companion animals, and laboratory animals. 

This section also encourages submissions describing emerging research areas, such as the effects of foods and food constituents on gene expression, nutrigenomics, and the effects of genetic variation on the absorption, metabolism, elimination, and biological outcomes of nutrients. Other specific topics of interest include food, malnutrition, vitamin deficiency, rumen fermentation, restricted feeding, inflammation, metabolic disorders, lifestyle-related illnesses (obesity, metabolic syndrome, diabetes, and hypertension), neoplasia, genetic diagnosis, and the development of supplements and drugs in animals.

COVID-19 Announcement

As a result of the significant disruption that is being caused by the COVID-19 pandemic we are very aware that many researchers will have difficulty in meeting the timelines associated with our peer review process during normal times.  Please do let us know if you need additional time. Our systems will continue to remind you of the original timelines but we intend to be highly flexible at this time. Thank you.
