CABI Book Chapter Info
Cover for Modelling production and portal appearance of volatile fatty acids in dairy cows.

Values of stoichiometric coefficients were estimated to describe the production of volatile fatty acids (VFA) from fermented substrate in the rumen of lactating cows. Coefficient estimates were derived by regression of in vivo data of rumen digestion to a stoichiometric model with non-linear...

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...

Cover for Advantages of a dynamical approach to rumen function to help to resolve environmental issues.

Simulation studies demonstrated the difference between current practice (static representation) and a dynamic representation of rumen function. Where current feed evaluation indicated absent or linear responses to changes in dry matter intake (DMI) and exchange of grass and maize silage, simulated...

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...

CABI Book Chapter Info
Cover for Modelling protozoal metabolism and volatile fatty acid production in the rumen.

The aim of this chapter is to describe two key aspects in the supply of absorbed nutrients, i.e. the quantitative representation of protozoal metabolism, and the quantitative representation of volatile fatty acid production in the rumen.

Cover for Production efficiency of ruminants: feed, nitrogen and methane.

This chapter discusses the production efficiency of ruminants, particularly cattle, in relation to feeds, nitrogen excretion and methane emission. Focus is given on the production efficiency of cattle, primarily that of dairy cattle, at the animal level. Improvements in production efficiency are...

Cover for Evaluation of models to predict methane emissions from enteric fermentation in North American dairy cattle.

The increasing focus on the environmental impact of agriculture means that there is a need for an accurate inventory of greenhouse gases (GHGs) to identify main sources of pollution and evaluate effects of potential mitigating options. A number of models have been developed to predict methane...

Cover for Integrated approaches to evaluate nutritional strategies for dairy cows.

This chapter discusses the possibility of applying more integrated approaches when evaluating nutritional strategies for dairy cows, simultaneously in detail and from several aspects. The different levels of aggregation that may be covered by models are shown. Primarily, the chapter handles the...
