Tropical pasture utilization by L R Humphreys 205pp 1991 ISBN 052138030 8 published by Cambridge University Press Trumpington Street Cambridge CB2 1RP UK
Recent research suggests that the application of the old concepts of pasture management developed in Europe and the USA have been unsuccessful in the Tropics. In some areas under-utilization has resulted in poor animal output and low economic returns, whereas in other areas overgrazing has resulted in soil erosion and weeds. Tropical pasture utilization examines the problems involved and explains how pastures may be managed to meet the requirements of both plants and animals for growth and replacement. The author, Professor L R Humphreys, has been involved for many years in extensive research of Tropical and Subtropical pastures. Following an overview of the livestock systems of the Tropics, the effects of grazing animals on the edaphic, biotic and climatic environment of the pasture are described. The response of the animals to the available pasture are discussed in terms of pasture attributes of nutritive value and sward structure, selectivity and grazing behaviour. Methods for attaining continuity of forage supply are also described. The distinctive pasture characteristics of the Tropics, together with features of the climatic environment, lead to options for management whose emphases are different from those encountered in the management of temperate pasture and these are developed in this book.
