Shortcomings of the Energy Evaluation Systems in Pigs: a Review
2013, 78 (3) p. 153-158
Abstract
The aim of that review is to present the principles of energy evaluation systems used in pig feeding and to stress out some key consideration when introducing Net Energy (NE) systems and some areas of future research. Based on the relevant literature data it can be stated that despite the mentioned shortcomings of the currently used energy systems, we have to admit that NE and/or Potential Physiological Energy (PPE) are the least inaccurate feed evaluation, therefore they are recommended to use in practical pig production. There is not enough evidence to favor any of these systems. According to our opinion some kind of harmonization would be beneficial, since the European feed market would need a common understanding of energy (feeding) value of compound feeds and feedstuffs. However, according to our view it could be achieved only by the lobby and cooperative action of the European feed manufacturers.
