Containing a selection of the papers presented at the International Symposium of Modelling in Pig and Poultry Production 2013, this book brings together the best and most recent academic work on modelling in the pig and poultry industry, with a particular emphasis on nutrition. It reviews basic modelling concepts, descriptions and applications of production models and new methods and approaches in modelling. 606 $aPoultry$xPhysiology 606 $aAnimal culture 615 0$aPoultry$xPhysiology. 615 0$aAnimal culture. 676 $a636.4085 676 $a636.5089239 702 $aSakomura$b N.
