The utilization of pasture by the dairy goat was studied between May and July with "Alpine" goats from the 90th to 200th day of lactation. The animals, after fifteen days of transition with the winter feeding, grazed progressively first only in the day, then the day and the night. Every group of twelve goats grazed on plots of 50 m in length and 2-4 m in width according to the season. Every day the goats received 700 to 900 g of concentrate (barley and oats). The voluntary intake on pasture was estimated by the method of differences, the milk production was noted at every milking and the alimentary behaviour was registered by the technique of registering clocks. After three years concluded that the dry matter voluntary intake changed in important proportions from 20 DMg/W0.75 to 100 DMg/W0.75. The legumes were more ingested than the grass; among the legumes, the red clover was more ingested than the alfalfa, and among the grass the Italian rye grass preferred to the orchard-grass. The percentage of refused pasture was between 10 and 70 percent DM. The daily milk production was between 2-4 kg. The climatic factors (temperature and rain) were the more important factors of variation. In our experimental conditions, the ingestion time was diurnal after the milking (morning and evening); the rumination time was especially nightly
