Herbage of Mediterranean pastures in the last decade weakened the production with a consequence on livestock and on nvironmental landscape. Fertilizer application was used to improve soil fertility located in two pasturelands [Environment I (Gioi) and Environment II (Monterotondo)] of Mediterranean environment belonging to Campania and Latium districts, respectively. The effect of fertilizer applications on herbage was evaluated by grazing with buffalo heifers and tested with a similar folk bred in cattleshed. The effect of pastures improvement was assessed on undisturbed areas of sward herbage growth in protected cages. No variation in biochemical characteristics of topsoil was made by fertilizer application. The grass of sward was browsed by a group of 18 heifers during the period September 2005 to November 2006. The effect of treatment increased, in the period of pasture utilization March-June, the content of native pasture parameter: dry matter (53% at Environment I and 27% at Environment II), nutritive value of herbage (0.016 Milk Forage Unit at both environments), flora composition (mean over locations, Graminaceae, was higher 22.4 and Leguminosae and miscellaneous group both lower 15 point of percentage than the content of the flora of the native pasture) and weight body gain of buffalo heifers which browsed sward the improved pasture was higher 27.6% in Environment I and 26.8% Environment II than in native. The weight body gain of animal at grazing in comparison to those bred in cattleshed was lower 40% and 19.4% in native and 25.7% and 1.4% in improved of E I and E II pastures, respectively.
