The livestock sector is one of the fastest growing subsectors of the agricultural economy and,
while it makes a major contribution to global food supply and economic development, it also …

Genetic selection that has been carried out for several dozen years has led to significant
progress in poultry production by improving productive traits and increasing the profitability …

The aim of this study was to apply a life cycle assessment (LCA) method, from cradle to gate,
to quantify the environmental burdens per 1,000 kg of eggs produced in the 4 major hen-egg …

Different energy evaluating systems have been used to formulate poultry diets including
digestible energy, total digestible nutrients, true metabolizable energy, apparent …

Using accurate nutrient values for ingredients is of vital importance for efficient diet
formulation. The net energy (NE) system accounts for the real available amount of feedstuff …

Different energy systems have been proposed for energy evaluation of feeds for domestic
animals. The oldest and most commonly used systems take into account the fecal energy …

Feed incurs most of the cost of aquaculture production, so feed efficiency (FE) improvement
is of great importance. Our aim is to use work done in pigs to formulate a logical framework …

Feed energy is an important production factor in poultry, representing 75% of the total cost of
feed. Therefore, maximising energy digestion and utilisation is essential for cost …

Climate change has numerous effects on poultry that result in welfare concerns and
economic losses in agricultural industries. However, the mechanisms underlying the …

Precision livestock feeding aims to match nutrient supply precisely with the nutrient
requirements of individual animals, based on real-time feedback from sensors. The benefits …
