Cover for Metabolic control: improvement of a dynamic model of lactational metabolism in early lactation.

A mechanistic, dynamic model of metabolism exists to allow testing of complex hypotheses on nutrient metabolism of the dairy cow. The model describes protein synthesis and degradation in the viscera and muscle, lipogenesis and lipolysis in the adipose tissue, and milk synthesis. It is dynamic,...

Cover for Modelling fluxes of volatile fatty acids from rumen to portal blood.

A model was developed that describes the relationships between the production, the ruminal concentrations and the fluxes of volatile fatty acids (VFAs) across portal drained viscera (PDV). This study presents some preliminary results. Firstly, general steady state relationships between production...

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 The role of rumen fill in terminating grazing bouts of dairy cows under continuous stocking.

This experiment was aimed at studying the role of rumen fill in signalling the termination of grazing bouts of dairy cows using a combination of experimental and modelling approaches. The day was divided into three main periods (06:00-12:00 h, 12:00-18:00 h and 18:00-24:00 h) during which the three ...

Cover for Obtaining information on gastric emptying patterns in horses from appearance of an oral acetaminophen dose in blood plasma.

The rate of passage of nutrients from the stomach to the small intestine is a regulated process that can influence metabolic responses to a meal. Acetaminophen has been used as an indicator of gastric emptying because of its negligible absorption in the stomach and high coefficient of absorption in ...

Cover for Scientific progress and mathematical modelling: different approaches to modelling animal systems.

This chapter describes science and its progression, the role of and practice of mathematical modelling and the different approaches to modelling animal systems. This is done with particular reference to animal science, with examples from poultry and pigs. A key paradigm from each of the 3 branches...

Cover for Prediction of body weight and composition from body dimension measurements in lactating dairy cows.

Body composition data and live animal measurements were obtained from 146 Holstein × Friesian lactating cows. Live animal measurements were recorded 3 or 4 days prior to slaughter, including live weight (LW), body condition score (BCS), girth, belly girth, height and length. The objective was to...

Cover for Empirical model of dairy cow body composition.

The knowledge of body condition and dynamic body reserve changes in dairy cows is of major importance in the understanding of lactation processes. An empirical model of dairy cow chemical body composition was developed and fitted to literature data. This model was aimed at predicting the...

Cover for Simulating chemical and tissue composition of growing beef cattle: from the model to the tool.

This study deals with an improvement of a previously published mechanistic and dynamic model of beef cattle growth, the fitting and validation processes, and the inclusion of this model in a decision support (DS) tool. The improvement of the model consists in the modelling of body tissue...

Cover for Representation of fat and protein gain at low levels of growth and improved prediction of variable maintenance requirement in a ruminant growth and composition model.

We have refined a prediction system for ruminant animal growth and composition developed previously. The model represents body protein in two pools: viscera and non-viscera (muscle). Using sheep data-sets, we have simplified the adjustments in the model for protein gain and loss of body fat at near ...
