Abstract

<p>Mangalica pig is a Hungarian breed which was introduced to Tokachi in Hokkaido. However, there are few reports on related to the growth information of Mangalica in the world. Thus, we studied the growth information and carcass performance between Mangalica and commercial breed (Camborogh and LWD). The weight of Mangalica was 1.2±0.0 kg at birth, 63.8±1.2 kg at 6 months which was considered as a commercial shipping period, and the growth was more slowly than commercial pig and did not gain much weight after 15 months of age. In the carcass performance, the carcass weight of Mangalica did not increase after 18 months and this study was revealed that the back-fat thickness of Mangalica was equal to or larger than twice as thick as that of commercial pig. There was no difference in the melting point of lipid between both breeds although the differences were observed in fatty acid components, linoleic acid was low (P < 0.05) and oleic acid was high tendency (P < 0.10) compared to commercial pig. In conclusion, Mangalica was able to fatten in the grazing environment at Tokachi and we determined the appropriate shipping period of Mangalica was between 15 to 18 months.</p>
