The objective of the following research was to determine the effect of LGB genotypes on subclinical mastitis in Valle del Belice dairy sheep. Ewes were classified as affected or not by subclinical mastitis within a lactation based on i) a positive culture in one of the test-days and ii) more than 750,000 somatic cells. Generalized linear mixed models were fitted to assess the significance of LGB genotypes on MTB and MTC. The LGB genotypes significantly affected MTB (p=0.0387), and showed a tendency on MTC (p=0.1104). Least square means showed that in the analysis for MTB, individuals with genotypes BB and AB had a higher frequency of subclinical mastitis. Moreover, the least square differences showed that the incidence was significantly higher in BB ewes than in AA ewes (p<0.001), and a tendency of a higher incidence among AB ewes than in AA ewes (p=0.0630). In conclusion, the results of this work show that LGB genotype BB seems to be less favourable in terms of mastitis resistance in Valle del Belice sheep breed.
