The objective of this study was to verify if grazing goats were capable of choosing the concentrate grains that better interact with the quality of herbage intake in a free-choice feeding system. A native pasture in a Basilicata valley (Italy) was used for this experiment. Thirteen Maltese goats grazed for eight hours/day an area of 1.2 ha from 24 April to 7 July. Goats received barley and maize grain, beet-pulps, chick-peas and broad beans grain (hydrated in water), in unlimited amount and simultaneously. Each feed was offered in a single pail. For the first four weeks goats received the feeds only in the goat house, for the following seven weeks, apart from in the goat house, also on pasture. The herbage intake was estimated by four oesophageal-fistulated goats. The double concentrate distribution, in goat-house and on the pasture, did not modify the total concentrate intake (TCI): only less than 4 per cent was eaten on the pasture (0.038 kg vs 1.05 kg indoor).
