This study was conducted to investigate the effect of different feeding regimes on the quality of deer meat (venison) following storage at 4°C for various durations. Twelve 5-year-old elk stags about 350 kg were stratified by weight and randomly assigned to one of four dietary treatments (three elk stags per treatment). The dietary treatments consisted of a feeding concentrate of 1.5% of body weight (T1), feeding concentrate of 1.8% of body weight (T2), feeding concentrate (T3), or a home-mixed ration (T4). The pH values of deer meat were not significantly different among treatment groups but were affected by duration of storage. Cooking loss increased under T4 treatment with increasing storage time at 4°C (<0.05). Increased storage time also resulted in significant decreases in shear force under T2 and T3 treatment compared to that under other dietary treatments (<0.05). Lightness (L*), redness (a*), and yellowness (b*) parameters were not significantly different among treatment groups, but lower values of a* and b* were observed under T1 and T4 treatment with increasing durations of storage (<0.05). The chemical and fatty acid composition had no significantly different among treatments. Therefore, meat quality was most affected by increased storage time at 4°C. These results may serve as the basis for further study of deer meat (venison) from Korea.
本研究旨在调查不同饲养方式对鹿肉(鹿科动物肉)在4°C下储存不同时长后的品质影响。选取12头体重约350千克的5岁雄性麋鹿,按体重分层后随机分配到四种日粮处理组之一(每组三头麋鹿)。日粮处理包括:投喂占体重1.5%的浓缩饲料(T1)、投喂占体重1.8%的浓缩饲料(T2)、投喂浓缩饲料(T3)或自配日粮(T4)。各处理组鹿肉的pH值无显著差异,但受储存时长影响。在T4处理下,随着在4°C下储存时间的增加,蒸煮损失增加(<0.05)。与其他日粮处理相比,在T2和T3处理下,储存时间延长也导致剪切力显著降低(<0.05)。各处理组之间的亮度(L*)、红度(a*)和黄度(b*)参数无显著差异,但在T1和T4处理下,随着储存时间延长,观察到a和b值较低(<0.05)。各处理之间的化学组成和脂肪酸组成无显著差异。因此,肉品质受4°C下储存时间延长的影响最大。这些结果可为进一步研究韩国鹿肉(鹿科动物肉)提供依据。
