The aim of this study, carried out in the Tuscany Region (Italy), was to compare the animal welfare in conventional and organic dairy sheep farms. Recordings were performed on 4 farms (2 conventional and 2 organic) selected for large flock size (average: 725,00±64,55 heads) and 4 farms (2 conventional and 2 organic) selected for small flock size (average: 145,00±52,60 heads). A single trained observer performed the evaluation, using a derived protocol by Animal Needs Index (ANI 35 L), which relies on 7 assessment sheets. Only one visit was carried out in each farm. Modifications of ANI 35 L protocol were referred to animal based indicators: skin lesions and integument alterations, cleanliness, hooves conditions, lameness, evaluated on the basis of theirs prevalence (number of affected animals/number of observed animals). Longevity and mutilations, scored in terms presence/absence, were also included. The total derived ANI 35 L score (average: 48,37±7,53; min 36,00; max 58,50) for the different farming method (organic vs conventional) and flock size (large vs small) was analysed by non-parametric Kruskal Wallis test. No significant differences were observed between organic/conventional farms and large/small herds. The obtained results might be explained by the negligible difference in dairy sheep production: despite of farming methods and flock size, all rearing systems were extensive. Further investigations are required to improve the derived ANI 35 L protocol on dairy sheep farm; in particular, animal based indicators should be tested on farm to evaluate their validity in relation to specific variables (e.g. season, shearing) possibly affected the welfare assessment.
