The use of different oils in diets for broilers (A review)
The research in poultry nutrition is targeted at the adequate supply of protein and energy via the enhancement of the production and efficiency of the traditional sources and via the intense search for new sources and additives. The use of different dietary vegetable oils as energy sources for poultry also gains the increasing interest of scientists and practitioners. General aspects of this problem and different oils which are presently used in diets for broilers are reviewed. The oils and their combinations were found to beneficially affect muscle growth rates, feed efficiency, livability, and economic efficiency of broiler production since the oils are the promising sources of easily available energy and certain bioactive substances, e.g. essential fatty acids (linolic, linoleic, etc.). The effectiveness of different oils in broiler diets will depend on type and quality of the oil and inclusion rate; dietary contents of protein, energy, vitamins, and minerals; production system; cross and sex of the birds.
