Abstract

Massive ingestion in two 3 h meals within a Quercus pubescens Wild coppice at daily intervals of 10 h, supplemented by 450 g of barley and minerals, allowed a milk production of 2.5 lid 6 months after kidding (Meuret, 1989). Mapping at 1 :2 000 of the 11 0 ha of grazing land identified 605 homogeneous land units, according to 5 criteria organised into (n) classes: nature and structure of the vegetation (n = 7); penetrability (4); shrub cover (4); forage abundanoe (4); and forage consumption rate (4). A k-means clustering by Leas grouped the units into 5 synthetic classes. After 4 days' acclimatisation, a sample goat was continuously monitored by 2 observers during 1 0 consecutive meals. The grazing location, movements and ingestion (divided into intake units) were recorded continuously by direct observation (Meuret, 1989) and the data was grouped for each minute. Visible and audible interactions with the shepherd were noted. A 3rd observer recorded the activity pattern of the herd at 20min intervals by scanning all the 41 animals.
