Field and laboratory methods for grassland and animal production research.

Book cover for Field and laboratory methods for grassland and animal production research.

Description

This book brings together a range of methods used to study grasslands (both temperate and tropical) and ruminant performance, including: grassland vegetation and its measurement; pattern analysis in grassland and animal production systems; modelling pasture and animal production; measuring botanical composition of grasslands; measuring sward structure; plant population dynamics in grasslands; meas...

Modelling pasture and animal production.

The prediction of pasture and animal production using a series of mathematical equations based on various biophysical inputs which influence or control production is outlined. These equations are arranged in a computer program and know as a model. The terminology and concepts used in models are discussed. Types of models and the user groups to which they apply are described. Getting started as a model user and as a model builder are outlined. Full details are given of a basic soil-plant-animal model with pasture, animal and economic submodels.
