Abstract

The veining defect is usually localized under the skin on the medial side of the thigh. The defect appears some hours after pig death, becomes particularly visible during ham’s trimming and is still evident after the end of the dry-curing process. The assessment of the veining defect is made by a photographic scale which leads to a more precise and constant evaluation at trimming. Results of this study show an increase of veining incidence with the carcass leanness. Moreover, the frequency of veining defect is affected by the stunning method of pigs and by time that the thighs are not refrigerated after being separated from the carcass (pre-chilling time). The frequency of defect has increased by CO2 respect electronarcosis stunning and by prolonging the pre-chilling time.
