The goal of this study was to examine the seasonal variation in the body composition, carcass composition, and quality of edible internal organs from the fallow deer hunt-harvested in the summer ( = 9) and the winter ( = 10) seasons. The weight and proportion of the mesenteric and omental fat were greater for the animals harvested in the winter (1.12 kg and 2.75%) compared to those from the summer season (0.43 kg and 1.02%). The winter-harvested animals had more perinephric fat (0.75 kg and 1.84%) than those hunted in summer (0.26 kg and 1.84%). The gastrointestinal tract of the fallow deer hunted in summer was more filled with feed and therefore heavier (7.92 kg) compared to those from the winter season (5.16 kg). The proportion of fat was significantly greater in the carcasses obtained in winter compared to the summer season (6.55% vs. 3.79%). No seasonal variety was found in the physicochemical characteristics of the edible offal, but the content of extractable fat was significantly affected by the season. In conclusion, the effect of the season on the slaughter value of the hunt-harvested fallow deer was limited to a variation in the proportion of some of the internal organs and affected the fat deposition in the body of the examined animals. The season significantly affected the fat content in the carcass and the extractable fat content in the examined offal.
本研究的目的是检测夏季(n = 9)和冬季(n = 10)猎获的黇鹿的身体组成、胴体组成以及可食用内脏器官质量的季节性变化。与夏季猎获的动物(0.43千克和1.02%)相比,冬季猎获的动物肠系膜脂肪和网膜脂肪的重量及比例更大(1.12千克和2.75%)。冬季猎获的动物肾周脂肪更多(0.75千克和1.84%),而夏季猎获的动物肾周脂肪为(0.26千克和1.84%)。夏季猎获的黇鹿胃肠道内饲料填充更多,因此比冬季猎获的黇鹿更重(7.92千克 vs. 5.16千克)。与夏季相比,冬季获得的胴体脂肪比例显著更高(6.55% vs. 3.79%)。可食用内脏的理化特性未发现季节性差异,但可提取脂肪的含量受季节显著影响。总之,季节对猎获的黇鹿屠宰价值的影响仅限于部分内脏器官比例的变化,并影响了被检测动物体内的脂肪沉积。季节显著影响了胴体中的脂肪含量以及被检测内脏中的可提取脂肪含量。
