CABI Book Chapter Info
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 Animal products.

In this chapter, equations for milk yield from dairy cows are discussed, followed by energy utilization efficiency for milk production. The next two sections focus on meat production, body composition and allometry, leading to considerations of growth efficiency. Egg production and the amino acid...

Cover for Methodological considerations for measuring phosphorus utilization in pigs.

This chapter reviews the major processes of digestive and post-absorptive utilization of dietary P in pigs, examines the methodology for measuring wholebody P utilization and discusses the criteria developed for assessing P bioavailability in feed ingredients for formulating pig diets and...

Cover for Development of a dynamic model of calcium and phosphorus flows in layers.

Phosphorus (P) is involved in most metabolic activities of the body as well as in bone formation. P and calcium (Ca) are closely related so that a deficiency in one can interfere with proper utilization of the other. In layers, requirement for dietary P is mainly due to the need to store Ca in...

Cover for A kinetic model of phosphorus metabolism in growing sheep.

Research in Brazil has been carried out to study phosphorus (P) metabolism in ruminants, by using the isotope dilution technique. The purpose of this study was to use data from balance and kinetic experiments to solve a kinetic model of P metabolism in growing sheep fed with different diets. During ...

Cover for Dynamic simulation of phosphorus utilization in salmonid fish.

Minimizing phosphorus (P) wastes is a key factor for environmental sustainability of freshwater aquaculture operations. A dynamic model was constructed to simulate P utilization in salmonid fish through digestion, body deposition and excretion into urine and faeces. Dietary P was classified into...

Cover for A simple nutrient-based production model for the growing pig.

The basic principles for a simple nutrient partitioning model for the growing pig are outlined. The proposed model is meant for practical feed evaluation and is based on input data for the actual feed, the actual pig and the actual feeding situation. The system is composed of four steps, including: ...

Cover for An integrated cattle and crop production model to develop whole-farm nutrient management plans.

An integrated modelling approach is needed to efficiently utilize nutrients within the farm boundary to control the risk of non-point-source pollution while maintaining farm profitability. The Cornell University Nutrient Management Planning System (CuNMPS) is being developed for that purpose. The...
