The aim of this work is to study the influence of gender, age and hunting period on the fatty acid composition of the longissimus dorsi muscle excised from 42 wild boars hunted on a farm located in Tuscany.

Slaughtering age influenced more parameters, thus resulting in a higher content of C6:0, C18:2, C20:1 and n6/n3 ratio in meat from adults (p.05) and in a higher percentage of C16:0 (p.05) in meat from young animals. The hunting month greatly influenced the meat quality because, in addition to the single fatty acids, it significantly modified the MUFA, PUFA, PUFA/SFA and n6/n3 ratio, underlining the great difference between meat of wild boar shot in October – November vs December – January.

Abstract

The aim of this work is to study the influence of gender, age and hunting period on the fatty acid composition of the longissimus dorsi muscle excised from 42 wild boars hunted on a farm located in Tuscany. A sub-sample of 22 muscles was used for the study of the microbiological profile of wild boar meat. The results show that gender had an effect only on C16:1 n7, which was higher in females (p  .05). Slaughtering age influenced more parameters, thus resulting in a higher content of C6:0, C18:2, C20:1 and n6/n3 ratio in meat from adults (p.05) and in a higher percentage of C16:0 (p.05) in meat from young animals. The hunting month greatly influenced the meat quality because, in addition to the single fatty acids, it significantly modified the MUFA, PUFA, PUFA/SFA and n6/n3 ratio, underlining the great difference between meat of wild boar shot in October – November vs December – January. Ether extract was higher in sub- adults than in young animals (p.01) but was not influenced by gender and hunting month. Regarding the microbiological analyses, Salmonella spp. was only detected in one sample, while Yersinia enterocolitica was not detected at all. Data on the presence of pathogenic bacteria con- firmed health risk for the consumer comparable to that associated with meat obtained from farm animals, while data on microbial loads (total aerobic mesophilic and psychrotrophic counts, Enterobacteriaceae, Escherichia coli) did not highlight any specific criticality.
