During the first 3 tests there were no other sheep in sight and animals were alone with concentrate or with a human. During the last 2 tests some penmates were in sight and the experimental animal was alone or with a human. Romanov animals were much more reactive than the Merinos. They eliminated more ate less and avoided the human more. For most of the criteria crossbreds were closer to the Romanov than to the Merinos purebreds. This seemed to be due to genetic differences and not to direct maternal influence. sheep breed reactivity to man Merinos Romanov Resume Influence de la race sur le comportement d ovins vis-à-vis de la presence humaine. Des agnelles de deux races Merinos d Arles et Romanov et des croisées issues de mères Merinos saillies par des males Romanov ont été obervées dans cinq épreuves individuelles. Pendant les trois premieres épreuves il n y avail pas de congénères en vue et les animaux étaient seuls avec de I aliment concentre OU avec un homme. Pendant les deux demières épreuves des congénères étaient visibles dans un pare contigu et les animaux étaient seuls OU avec un homme. Les agnelles de race Romanov ont été beaucoup plus réactives que celles de race Mérinos d Arles. Elies defequaient et urinaient plus frequemment mangeaient moins et évitaient plus I homme. Pour la plupart des critères les croisées avaient des performances plus proches de celles des Romanov gue
