Using Net Energy for Diet Formulation: Potential for the Canadian Pig Industry
نویسندگان
چکیده
Feed is the greatest single cost factor in pig production. In pig diets, energy accounts for the largest proportion of the cost. Therefore, it is critically important that the energy content of a diet is characterized in the best possible way. There are several systems available for the characterization of dietary energy. The most common ones digestible and metabolizable energy describe the energy a pig can potentially derive from the feed. Net energy has been proposed as a superior system that describes the feed energy a pig actually does use. The following will describe these energy systems and make the case why net energy should be adopted by the Canadian pig industry.

Both plant and animal ingredients are used commonly to formulate balanced diets for poultry. Although many changes have been occurred in the genetics, nutrition and feeding of modern meat chickens, free selection and indiscriminate uses of feedstuffs for the non-ruminant animal diets can be hazardous due to the emerging threat of diseases outbreak via animal by-products. Besides this, many othe...

Demand for nonsolar energy and concern about the implications of fossil fuel combustion have encouraged examination of energy use associated with agriculture. The United States is a global leader in pig production, and the United States swine industry is centered in Iowa. Feed is the largest individual input in pig production, but the energy consumption of the Iowa swine feed production chain h...
متن کاملEnergy Evaluation of Feeds for Pigs: Consequences on Diet Formulation and Environment Protection1
The cost of feed is the most important cost in pig meat production (about 60%), and the energy component represents the greatest proportion. Therefore, it is important to estimate precisely the energy value of feeds, either for least-cost formulation purposes or for adapting feed supply to energy requirements of animals. Evaluation of energy content of pig feeds is usually based on their digest...
