Nutritional Modelling for Pigs and Poultry

Modelling is a useful tool for decision making in complex agro-industrial scenarios. 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.

5. Statistical issues in nutritional modeling

6. Basics and applications of an exponential N-utilization model (‘Goettingen approach’) for assessing amino acid requirements in growing pigs and meat type chickens based on dietary amino acid efficiency

7. Artificial neural networks

8. Challenges associated with the application of poultry models: the case of turkeys
