摘要
Pannon White rabbits of average ± 1 S.D. live weight at 10 weeks and of average
± 1 S.D. daily weight gain between 6 and 10 weeks of age were chosen from the experimental stock of our university, and their fat content was determined with an EM-SCAN SA-3152 type small animal body composition analyser (by means of TOBEC method) at 10 weeks of age. Based on the fat content determined, the best and worst 16% of the does and the best and worst 8% of the bucks were chosen and mated with each other (fatty doe with fatty buck and lean doe with lean buck). Their offspring were examined by computer tomography (CT) weekly between 6 and 11 weeks of age. Cross-sectional images (scans) were taken from the scapular arch to the end of the femur on each animal. From this scans the amount of fat was determined and its ratio to the total amount of body was calculated in the scapular, perirenal and pelvic region. In the most cases it was established that the total body fat content and also fat content in the scapular, perirenal and pelvic regions are significantly higher in the offspring of fatty rabbits as in the offspring of non-fatty ones. In the group of non-fatty rabbits the scapular fat increased intensively from the age of 7 weeks. The perirenal fat content began to grow rapidly at 8 weeks in fatty group and at 10 weeks of age in the non-fatty rabbits. Based on the results of this experiment TOBEC method seems to be a useful thing for selecting rabbits based on their body fat content.

平均±1标准误差的PANNON白兔在平均±1标准误差为10周和生活质量日增重周龄6至10名来自我校的实验股票被选中，和它们的脂肪含量与该EM-SCAN的SA-3152型小型动物体成分分析仪（由TOBEC法的装置），在10周龄确定。基于所确定的脂肪含量，一年中最好的和最差的16％的功能以及雄鹿队的最佳和最差的8％被选中，并相互配合（DOE脂肪脂肪降压和精益母鹿与精益降压）。他们的后代在6和11周龄之间检查计算机断层扫描（CT），每周一次。横截面图像（扫描）取自肩胛拱在每个动物股骨的末端。从该扫描的脂肪的量来确定，其比例以体的总量，计算在肩胛，肾周和骨盆区。在大多数情况下，它建立的总身体脂肪含量和还脂肪含量在肩胛，肾周和骨盆区是显著高于脂肪酸兔的后代中的非脂肪的人的后代。在该组非脂肪兔肩胛脂肪从7周龄集中增加。肾周脂肪含量就开始在非脂肪兔迅速8周在脂肪酸基团和10周龄生长。基于该实验的结果TOBEC法似乎是用于选择基于其体内脂肪含量兔一个有用的东西。
