Abstract: The problems of defining and measuring the productivity of grazing and foraging livestock are reviewed. It is proposed that the economic margin per unit of forage is an appropriate index of productivity for many livestock production systems, allowing comparison of the efficiency with which different types of livestock in different management systems produce economic margins from a forage resource. A method of estimating this index from a set of production parameter estimates is described. Applications of the index to evaluate changes in the management of livestock production systems and to compare the efficiency of alternative production systems are discussed. |
