The efficiency of the radiocesium binders-AFCF and clinoptilolite in broiler chickens exposed to alimentary contamination with 137Cs

Abstract

Various radioprotective agents are used with the aim of protecting animal and food of animal origin from radioactive contamination. The most efficient radiocaesium binder in animals is ammonium ferric hexacyanoferrate (AFCF). Based on the results obtained so far it can be concluded that the protection efficiency of AFCF in broiler meat and liver was 88%, after a single 137Cs contamination, followed by immediate AFCF administration via gastric tube while when mixed in the feed pellets this rate increased to 95%. In broiler chickens given clinoptilolite via gastric tube, the protection efficiency for meat and liver was 50%, while clinoptilolite mixed in the feed pellets showed the lowest protection efficiency in meat and liver of only 28%.

U cilju zaštite životinja i namirnica animalnog porekla od radioaktivne kontaminacije koriste se različita radioprotekciona sredstva. Kao najefikasniji radioprotektor kod životinja se pokazao amonijum-gvožđe (III) heksacijanoferat (II) ili AFCF. Na osnovu dobijenih rezultata se uočava da je u mesu i jetri brojlera posle jednokratne kontaminacije 137Cs i istovremenog davanja AFCF putem sonde efikasnost zaštite iznosila 88,0%, dok je AFCF umešan u hranu pokazao veću efikasnost zaštite od 95,0 %. Kod brojlera koji su dobijali klinoptilolit putem sonde efikasnost zaštite je bila preko 50,0 % u mesu i jetri, dok je klinoptilolit umešan u hranu pokazao najmanju efikasnost zaštite koja je iznosila 28,0 % u mesu i jetri brojlera.
