integer and stochastic model for evaluating production
alternatives
1983. vii + 95 pages. Paperback. 25.5 x 17.7 cm. ISBN 92-9053-016-
2 (E) and ISBN 92-9053-041-3 (F). Alsoavailableon microfiche: ISBN

Presents the rationale and formal specifications of a simulation
model used to evaluate cattle herd production dynamics. In the
model a herd is simultaneously represented as both a biological and
an economic unit. The analytical background and the model are
explained in detail and the simulation of feed intake, growth and milk
production, reproduction and mortality is discussed. The policy
options in herd management are also presented.
Available in English and French.
