Diet composition, dry matter intake (DMI) and digestibility (DMD) were estimated on three occasions using the alkane technique, and all animals were periodically weighed to calculate bodyweight (BW) changes per livestock unit (LU). Goats selected higher proportions of shrubs than the other herbivore species (P &amp;lt; 0.001). Overall, daily DMI was higher (P &amp;lt; 0.001) in equines (218 g\/kg BW0.75) than in ruminants (174, 121 and 80 g\/kg BW0.75 for cattle, goats and sheep, respectively), whereas DMD was lower (P &amp;lt; 0.001) in equines (569 g\/kg DM) compared with ruminants (733\u2013791 g\/kg DM). During the first half of the grazing season (from late April to mid-July), dams\u2019 BW changes per LU did not differ between species. However, during late summer\u2013autumn lower (P &amp;lt; 0.001) BW losses per LU were observed in sheep and goats (\u201389 g\/day) than in cattle (\u2013534 g\/day), being intermediate in horses (\u2013254 g\/day). For the overall grazing season, ewes and goats showed greater (P = 0.056) BW gains per LU (338 g\/day) than cows and mares (178 g\/day). Regarding the offspring, BW gains per LU were greater (P &amp;lt; 0.001) in lambs (3612 g\/day) than in other species. Calves presented greater gains than kids (2647 vs 1909 g\/day.LU), whereas foals showed intermediate gains (2385 g\/day.LU). Therefore, under these conditions of partially improved heathlands, sheep was the most productive species. However, looking at the diet selection and digestibility, goats could complement sheep or cattle herds by achieving a more efficient utilisation of heathland vegetation, and increasing overall productivity per hectare. By contrast, horses, having high levels of grass intake, compete with cattle and sheep for pasture utilisation.<\/jats:p>","DOI":"10.1071\/an15153","type":"journal-article","created":{"date-parts":[[2015,9,22]],"date-time":"2015-09-22T01:13:24Z","timestamp":1442884404000},"page":"102-109","source":"Crossref","is-referenced-by-count":29,"title":["Forage intake, digestibility and performance of cattle, horses, sheep and goats grazing together on an improved heathland"],"prefix":"10.1071","volume":"57","author":[{"given":"K.","family":"Osoro","sequence":"first","affiliation":[{"name":"AServicio Regional de Investigaci\u00f3n y Desarrollo Agroalimentario (SERIDA), 33300 Villaviciosa, Asturias, Spain."}]},{"given":"L.
