Description
Key-points
-
Models predicting intake and performance of grazing ruminants from animal, sward, grazing and supplements characteristics are rare, but they are now included in several decision support systems (DSS).
-
An evaluation of the performance and accuracy of published models are rarely undertaken by their authors, but this is proposed in this paper.
-
There is still a need for experimental research but also for the development of generic and dynamic models to predict intake and performance over a wide range of grazing conditions.
