About this Research Topic
New studies focused on defining nutritional requirements of food producing animals are essential to assist with updating nutrient requirement publications, such as the NRC, CSIRO, AFRC, BR-CORTE, INRA. Although these publications are extremely useful in formulation diets that meet the nutrient requirements of livestock used for food production, they can become outdated. With current animal feeding technologies (growth implants, beta agonists, etc.) and improved genetic selection technologies, food producing animals have become more efficient (e.g. increased growth rate, decreased fat deposition, improved milk production, etc.). Thus, updating nutrient requirements for a changing livestock population is extremely important. Our goal is to publish outstanding research on nutrient requirements for dairy and beef cattle, sheep, swine, and poultry to assist with updating nutritional requirements. Moreover, investigating the nutritional needs of local breeds is crucial for all those areas of the world based on a rural economy and on the development of typical products that can guarantee their subsistence.
Our goal is to encourage the publication of articles related to energy, protein, macro-mineral and trace-mineral requirements for farm animals, mainly local breeds. Moreover, it is important to highlight that articles focusing on environmental impact of new nutritional programs in line with new global political strategies are also of our interesting. These articles may be used by nutritional systems as a basis for updating nutrient requirement recommendations for livestock. These studies will be important to help nutritional systems (NRC, BR—Corte, CSIRO, etc.) clarify and update information on nutrient requirements. This will be useful for nutritionists and farmers to formulate more precise diets that would help to decrease costs and reduce nutrient excretion which would improve production efficiency while reducing the impact of nutrient excretion on the environment (e.g. nitrogen and phosphorus).
This Research Topic welcomes, but is not limited to, papers on the following themes:
• The energy, protein, and mineral requirements for dairy and beef cattle, poultry, pigs and sheep.
• The environmental impact of new nutritional programs in line with new global political strategies.
• The nutritional requirements of local breeds.
