Sažetak
Due to quality and relatively low price as a result of a simple and short production cycle, poultry meat occupies a very high position in the consumption of foodstuffs of animal origin. It is just because of such simple and rapid production that, under the circumstances of larger-scale radioactive contamination, poltry meat might become the main source of protein of animal origin. This fact, as well as the fact that no investigation into the effects of radioactive phosphorus on fattening chickens has been conducted so far, induced us to investigate the impact of lethal quantity of thic isotope an chickens at slaughter age. The investigation was performed on chickens, hybrids of the Jata haevy breeds of both sexes, aged 50 days and with a mass ranging from 1500 to 2000 g. The experiment was based on the application of radioactive phosphorus 32P at 333MBq/kg of body mass. Test animals were clinically examined, blood samples were taken for haematological analysis and, immediately after death, dissection and pathohistological examination were performed. Based on the obtained results it was concluded taht radioactive phosphorus, when applied to 50-day-old chicken causes: 1)anaemia, manifested by a decrease in erythrocyte count on the5th day and decreased haematocrite values 7 days post-contamination ; 2) leukopenia, decreased lymphocyte count ot the 1st day ; decreased eosinophil count on the 3th day, and decreased heterophil count 5 days post-contamination ; 3) thrombocytopenia, on the 5th day post-contamination ; 4) onset of clinical signs of radiation sickness on the 6th day and death of all contaminated animals on the 9th and 10th days post-contamination. Pathoanatomic examination of dead animals revealed dotted bleeding sites on heart and mucous membranes of digestive tract, as well as changes in parenchymal organs. Pathohistological changes confirmed the findings of pathoanatomic examination, which indicated the changes cased by radioactive radiation.
