Mediterranean pastures management by local cattle breeds for the valorization of typical products and for the development of nature tourism

Staglianò N., Argenti G., Albertosi A., Bianchetto E., Pardini A.

A trial was established in a private farm of Tuscan Maremma, that had recently set up an organic meat production system. The farm was grazed by Chianina cattle from the end of winter to autumn, and the animals were supplemented with alfalfa hay during summer, and maize silage during winter. Grazing impact on pastures was assessed from botanical composition and specific contribution, herbaceous species biodiversity, herbage height, seasonal and total annual forage production. The pastures distant from the stable and farm buildings were under-grazed, and consequently, their botanical composition became worse due to the overspreading of tall grasses and shrub encroachment. Until now pasture productivity remained almost unchanged, however the few animals used were not sufficient to maintain the current pasture resources. Consequently, the present number of reared animals (59 Livestock Units) is not enough in comparison with the calculated pasture carrying capacity (1.13 LU in the year average) and suggests the reduction of pasture area, at the same time managing forest reintroduction. Forage productivity was good (7.6 t DM/ha in native pastures, 8.1 in sown firebreaks and 10.0 in sown pastures) and this suggests concentrating management efforts in the most productive areas. Land care will contribute to developing naturalistic activities, especially by equipping resting areas and trekking paths and organization of tourist services. In some farms of the region this is already used to generate incomes.

L'expérimentation a été conduite dans une exploitation agricole de la Maremma toscane qui a récemment mis en oeuvre un système de production biologique de viande. Les animaux, de race Chianina, séjournaient au pâturage pendant toute la période fin hiver - automne. Le complément était assuré par du foin de Medicago sativa et de l'ensilage de maïs, respectivement en été et en hiver. Le nombre des animaux (59 UGB) était inférieur à la charge potentielle. La productivité était élevée (7,6 t MS/ha dans la pâture, 8,1 dans les coupures de combustible améliorées et 10,0 dans les pâtures semés avec des espèces fourragères). Les observations conduites suggèrent la réduction de la surface pâturée, la réintroduction de la forêt et la concentration des efforts sur les surfaces les plus productives. L'entretien du paysage peut contribuer au développement des activités naturalistes.
