Consumption quality of cold smoked meat of male hybrids from Lithuanian indigenous wattle pig with wild boar intercross
The aim of the study was to compare the quality of salted cold smoked meat of 1/4 WB and 1/2 WB (wild boar) genotype hybrid entire and castrated males from Lithuanian indigenous wattle pig with wild boar intercross. There was no significant effect of the genotype on back fat thickness at the lumbar region, but entire boars had 7.3-11.1 mm smaller (P < 0.001) lumbar back fat thickness at three points above m. gluteus medius. There were no statistically significant effects of genotype and gender on thawing loss and production yield of m. semimembranosus (SM). The panel study indicated no statistically significant effects of the genotype on cold smoked SM smell, tenderness, flavor and juiciness, but samples from 1/2 WB genotype had higher salinity (P < 0.001). Samples of salted cold smoked from castrates had higher scores in smell and flavor (P < 0.01) but lower in tenderness (P < 0.01) and juiciness (P < 0.001). A significant negative correlation was found between the age of entire boars and smell (P < 0.05) and weight of animal and product salinity (P < 0.001). The concentration of testosterone in plasma was negatively correlated with salinity (P < 0.001). In the consumer panel study joints from castrated males had higher scores for smell (P < 0.001) and flavor (P < 0.05), but the lean/fat ratio (P < 0.001) and the visual appearance (P < 0.05) were judged to be poorer than those of entire boars. Consumers have found pork from hybrid entire boars to be acceptable.
