Metabolizable energy is a key indicator of feed nutritional value, reflecting the amount of energy that livestock animals and poultry can absorb to maintain vital functions, growth, and productivity. Understanding the energy value of a ration is the foundation of modern animal husbandry. For agronomists and farm specialists, accurate calculation of metabolizable energy allows for the optimization of compound feed costs, improvement in the efficiency of rearing young stock, and an increase in dairy and meat productivity indicators, while avoiding unjustified overconsumption of feed resources.
This collection gathers expert materials covering both the fundamental principles of nutritional requirements and the applied aspects of working with various species of livestock animals and poultry. Readers will find science-based methods for ration formulation, examples of standardized feeding for lactating cows and sheep, as well as recommendations on the use of starter compound feeds. In addition to feeding issues, the articles cover technologies for keeping breeding poultry, methods for analyzing milk productivity, and key processes for processing livestock products, which ensures a comprehensive approach to managing an efficient farm.
