The present study investigated the possible differences in carcass composition as well as texture, structure and percentage of different muscle types of the most valuable muscles (BF – biceps femoris, SM – semimembranosus, and L – longissimus) from fallow deer (Dama dama L.) bucks shot in the forest farm in north-western Poland at four different ages: 18, 30, 42 and 54 months. It was found that carcasses of young fallow deer (18–30 months), compared to older animals, were characterised by a higher dressing proportion, a higher percentage of the most valuable commercial cuts (the saddle, haunch and shoulder), high meat yield with the lowest percentage of bones and a lower percentage of skin and head. Their muscles, compared with older animals, were characterised by a lower percentage of red fibres, lower muscle fibre area, thinner perimysium and endomysium, lower amount of intramuscular fat and as a consequence lower hardness, springiness, cohesiveness, as well as a higher pH and lower thermal drip.

小鹿the体组成和肉质与年龄相关的变化(DAMA DAMA L.

本研究调查了fall鹿(Dama dama)在最有价值的肌肉(BF –股二头肌,SM –半膜肌和L – longissimus)的car体组成以及质地,结构和不同肌肉类型的百分比上可能存在的差异。(L.)雄鹿在波兰西北部的森林农场里以四个不同的年龄射击:18、30、42和54个月。研究发现,与较大动物相比,幼小鹿(18–30个月)的ses体具有更高的敷料比例,最有价值的商业割肉(马鞍,臀部和肩部)的比例更高,肉产量高的特点。骨骼的百分比最低,皮肤和头部的百分比较低。与年长的动物相比,它们的肌肉的特征是红色纤维的百分比较低,肌纤维区域较小,肌膜和内膜更薄,肌肉内脂肪的含量较低,因此硬度,弹性,内聚性较低,pH值较高。并降低热滴。
