北京填鸭含脂肪量约占体重的40%,而辐照分解产物的含量与脂肪含量的多少有关。为了确保食用安全,我们用经~(60)钴γ-射线2500戈瑞辐照的冻(?)肉和油,以刚离乳的 Wistar 大鼠进行了90天喂养试验和大、小鼠的染色体畸变分析。结果表明喂饲辐照冻鸭肉和油的大鼠外表和行为与对照组没有任何区别,在生长发育,食物利用系数,血液的常规指标和生化指标,以及脏体比、脏器的病理检查等与对照组比较均无统计学上的显著性差异。大鼠骨髓染色体及小鼠睾丸染色体畸变分析,在实验组与对照组之间亦无统计学上的显著性差异。本研究表明该辐照冻鸭对实验动物无不良影响。
Beijing ducks contain approximately 40% of body weight, and the amount of irradiated decomposition products is related to the amount of fat. To ensure food safety, we carried out 90-day feeding trials and large- and young-born mice with fresh-frozen Wistar rats irradiated with ~60 gamma-ray 2500 Gy of irradiated meat and oil. Chromosome aberration analysis. The results showed that the appearance and behavior of rats fed with irradiated frozen duck meat and oil were no different from those of the control group. The growth and development, food utilization coefficient, blood routine and biochemical indicators, and the pathological examination of the body and body ratio and organ There were no statistically significant differences between the controls and the control group. There was also no statistically significant difference between the experimental group and the control group in the chromosome aberrations of rat bone marrow chromosomes and mouse testis. This study showed that the frozen duck had no adverse effects on experimental animals.
