The aim of the present study was to investigate distribution of (137)Cs in leg and breast meat of broilers and pheasants following single alimentary contamination and administration of two protectors (AFCF and clinoptilolite). The birds were administered a single dose of (137)CsCl, with an activity of 750 Bq. Protectors were given via gastric tube or mixed in the forage pellets. AFCF given via gastric tube decreased the (137)Cs concentration by a factor of 7.8 in broilers leg meat and 7.4 in broilers breast meat. When AFCF was mixed in pellets, the (137)Cs concentration was 19.5 times lower in broilers leg meat and 22.1 times lower in broilers breast meat, than in the control group. In pheasants, AFCF administered via gastric tube decreased the (137)Cs concentration by a factor of 12.4 in leg meat and by a factor of 13.7 in breast meat, respectively. In group 4, where pheasants were administered AFCF mixed in pellets, the (137)Cs concentration was 3.7 times lower in leg and breast meat, than in the control group. For comparison, clinoptilolite administered via gastric tube decreased the (137)Cs concentration 1.8 times in broilers leg meat and 2.0 times in breast meat, compared to the control group. In pheasants, (137)Cs concentration was 2.9 times lower in leg meat and 2.6 times lower in breast meat. Clinoptilolite mixed in the feed had relatively low efficiency of protection in broilers ((137)Cs concentration was 1.4 times lower in leg meat and 1.6 lower in breast meat). A similar trend was observed in pheasants ((137)Cs concentration was 1.6 lower in leg and breast meat).
本研究的目的是调查单次经口污染并给予两种保护剂（AFCF和斜发沸石）后，(137)Cs在肉鸡和雉鸡腿部及胸肉中的分布情况。给这些鸟类单次投喂750 Bq活度的(137)CsCl。保护剂通过胃管给药或混入饲料颗粒中。通过胃管给予AFCF后，肉鸡腿部肌肉中(137)Cs浓度降低了7.8倍，胸肉中降低了7.4倍。当AFCF混入颗粒饲料中时，肉鸡腿部肌肉中(137)Cs浓度比对照组低19.5倍，胸肉中低22.1倍。在雉鸡中，通过胃管给予AFCF后，腿部肌肉中(137)Cs浓度分别降低了12.4倍，胸肉中降低了13.7倍。在第4组中，给雉鸡投喂混入颗粒饲料的AFCF，腿部和胸肉中(137)Cs浓度比对照组低3.7倍。作为比较，与对照组相比，通过胃管给予斜发沸石后，肉鸡腿部肌肉中(137)Cs浓度降低了1.8倍，胸肉中降低了2.0倍。在雉鸡中，腿部肌肉中(137)Cs浓度低2.9倍，胸肉中低2.6倍。饲料中混入斜发沸石对肉鸡的保护效率相对较低（腿部肌肉中(137)Cs浓度低1.4倍，胸肉中低1.6倍）。在雉鸡中也观察到类似趋势（腿部和胸肉中(137)Cs浓度低1.6倍）。
