A quelle vitesse les modèles d'élevage de demain peuvent-ils se généraliser et modifier la localisation des productions de viande bovine ?

Little research in France is directly concerned with the estimation of the rate of diffusion of technical progress and the speed with which animal produce markets, especially beef-production, are set up. The paper presented here is, thus, exploratory. It does not dwell on the question of localization. After having shown the ambiguity of what is known as a cattle-breeding model, we intend to examine the manner in which diffusion of specialised types of activities depends on the degree of control attained on the technical and economic levels. Taking examples from the activities of a dairy-herd, it can be shown how each of them has developed over the last few years. Going on to deal with the activities of a meat producing herd, we try to pick out the factors which may be favourable to their rapid diffusion.
