Title: | Factors affecting energy metabolism and evaluating net energy of poultry feed | Contributor(s): | Barzegar, Shahram (author); Wu, Shu-Biao (author) ; Choct, Mingan (author); Swick, Robert A (author) | Publication Date: | 2020-01 | Early Online Version: | 2019-12-30 | Open Access: | Yes | DOI: | 10.3382/ps/pez554 | Handle Link: | https://hdl.handle.net/1959.11/29312 | Abstract: | Different energy evaluating systems have been used to formulate poultry diets including digestible energy, total digestible nutrients, true metabolizable energy, apparent metabolizable energy (AME), and effective energy. The AME values of raw materials are most commonly used to formulate poultry diets. The net energy (NE) system is currently used for pig and cattle diet formulation and there is interest for its application in poultry formulation. Each energy evaluating system has some limitations. The AME system, for example, is dependent on age, species, and feed intake level. The NE system takes AME a step further and incorporates the energy lost as heat when calculating the available energy for the production of meat and eggs. The NE system is, therefore, the most accurate representation of energy available for productive purposes. The NE prediction requires the accurate measurement of the AME value of feed and also an accurate measurement of total and fasting heat production using nutritionally balanced diets. At present, there is limited information on NE values of various ingredients for poultry feed formulation. The aim of this review is to examine poultry feed energy systems with the focus on the NE system and its development for chickens. | Publication Type: | Journal Article | Source of Publication: | Poultry Science, 99(1), p. 487-498 | Publisher: | Elsevier BV | Place of Publication: | Netherlands | ISSN: | 1525-3171 0032-5791 |
