CABI Book Chapter Info
Cover for Animal organs.

This chapter considers compartmental models which simulate whole organ function, with reference to ruminants. The organs considered in some detail are the mammary gland and the rumen. Essentially, the models are expressions of rate:state formalism, but here they are non-linear and must be...

CABI Book Chapter Info
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 Animal husbandry.

This chapter considers simple models for use in animal husbandry. Problems considered are ration formulation, allocation to feeding groups, effects of feeding on milk production and liveweight, pattern of calving and replacement. The chapter focuses on mathematical programming applications, thus...

Cover for Simulation of rumen particle dynamics using a non-steady state model of rumen digestion and nutrient availability in dairy cows fed sugarcane.

An extant dynamic model of digestion and absorption of nutrients in cattle fed sugarcane was adapted for non-steady state feeding conditions. This modified model includes mechanisms of particle size reduction and delay in availability of particles and intracellular contents for microbial...

Cover for The diary of Molly.

A discussion on the development and creation of a predictive model for lactation potential (Molly) which is able to describe the effects of nutrition and animal factors on milk yield and dairy performance in general, is presented.

Cover for A composite model of growth, pregnancy and lactation.

Mathematical models of pre- and postnatal growth, pregnancy and lactation were combined and implemented using object-orientated computer code to form an energy-based model of a dairy cow. Each simulated cow 'grows', can have a computer pregnancy with multiple offspring, growing its fetuses to term, ...

Cover for Modelling interactions between cow milk yield and growth of its suckling calf.

A simple mechanistic model of the relationship between cow milk production and suckling calf growth is described. In this model, milk secretion of the mammary gland is regulated through the amount of milk currently present in the udder (short-term regulation) and through the amount of the...

Cover for The Nordic dairy cow model, Karoline - evaluation.

This study presents evaluation results of the model Karoline, which is described in another study (see Danfær et al., Chapter 32, this volume). The validations comprise behavioural analyses, testing against experimental data and comparison of Karoline with the Cornell Net Carbohydrate and Protein...

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...
