Modelling nutrient utilization in farm animals.

Book cover for Modelling nutrient utilization in farm animals.

Description

This book presents edited and revised versions of papers presented at the Fifth International Workshop on Modelling Nutrient Utilization in Farm Animals, held at the University of Cape Town, Cape Town, South Africa, 25-28 October 1999. There are 31 chapters and 6 sections entitled ruminal metabolism, absorption and metabolism, growth and development, ruminant production in various situations, nutr...

Chapter 24 (Page no: 317)

Modelling relationships between homoeorhetic and homoeostatic control of metabolism: application to growing pigs.

Diet formulation has to consider the multiple responses of animals to the diet. Their responses are assessed and expressed in terms of feed efficiency, quality of the food product, environmental impact and animal behaviour, welfare and health. To achieve this new purpose the first step is to apply a systemic approach to the organism acknowledging the major driving forces of nutrient fluxes and the second step is to model these forces. This chapter deals with these aspects in the case of the growing animal. Although the model presented only includes the minimum of information necessary to simulate growth and influences of diet, it was capable of realistic simulations of the metabolic flow during growth and during a shortage of amino acids.
