CABI Book Info
Cover for Mathematical modelling in animal nutrition.

The primary purpose of each of the subsequent chapters of this book is to promulgate quantitative approaches concerned with elucidating mechanisms in a particular area of the nutrition of ruminants, pigs, poultry, fish or pets. Given the diverse scientific backgrounds of the contributors of each...

Cover for Supporting measurements required for evaluation of greenhouse gas emission models for enteric fermentation and stored animal manure.

This chapter briefly reviews processes and controlling factors involved in greenhouse gases (GHG) production and emission associated with animal production as well as the currently used models that describe GHG emissions for animal production. Supporting measurements and reporting standards for GHG ...

Cover for Data capture: development of a mobile open-circuit ventilated hood system for measuring real-time gaseous emissions in cattle.

This chapter describes a mobile, open-circuit ventilated hood system for measuring real-time gaseous exchange in large ruminants at the farm level. It uses improvements in technology for the determination of O2, CO2 and CH4 contents, measurements of air flow, absolute pressure, temperature and...

Cover for Compartmental models of protein turnover to resolve isotope dilution data.

In this chapter, the applications in the animal sciences of dynamic modelling, based on the rate:state formalism, with Type I solutions are illustrated. This chapter deals with modelling animal processes, i.e. specific components or functions of an individual organ or tissue (or whole organism)....

Cover for Mathematical representation of the partitioning of retained energy in the growing pig.

The focus of this review is the assessment of calculation rules to represent the partitioning of retained energy between body protein deposition (Pd) and lipid deposition (Ld) when Pd is driven by energy intake. During this energy-dependent phase, Pd is not limited by the animals' upper limit to Pd ...

Cover for Modelling phosphorus metabolism.

In this chapter, examples of empirical, kinetic and mechanistic models of phosphorus (P) metabolism in ruminants and monogastric animals, viz. cattle, goats, sheep, horses, pigs and poultry, are discussed. The mechanistic models of P flow in ruminants and monogastric animals described in this...

Cover for A model to simulate the effects of different dietary strategies on the sustainability of a dairy farm system.

A new model is being developed to study the main elements that affect sustainability within a dairy farm by using multiple goal programming. In this work, we describe the main characteristics of this modelling approach and we evaluate, via optimization, the effect of different dietary strategies...
