Haemotoxicity to chicken (Gallus gallus domesticus) by technical and formulation grades of some phosphoric and synthetic pyrethroid esters.

Acute toxicity was studied by administering an encapsulated single dose to chickens (G.g. domesticus) and observing them for 21 days. Azodrin-71 (Tech.) was found to be extremely toxic, whereas Cypermethrin-92 (Tech.), Cypermethrin-25 EC and Permasect-25 EC (Form.) were practically non-toxic based on LD50 value determinations. Sub-acute oral haemotoxicity of technical and formulation grades of these insecticides was also studied by administering encapsulated low, medium and high daily doses for 21 days to chickens and recording clinical symptoms, mortality and haematological parameters pre and post-dosing. Clinically high doses of Azodrin-71 (Tech.) caused tremors and ataxia among chicks on the 10th day after dosing. Synthetic pyrethroids caused slight tremours in the whole body accompanied by salivation. In general, hyperactivity to external stimuli and loss of appetite and body weight were also observed. With sub-acute oral doses, Permasect-25 EC (Form.) more potently affected haemoglobin (Hb), red cell (RBC) counts and chloride level. Cypermethrin-92 (Tech.) was most potent towards thrombocytes and clotting time. Azodrin-71 (Tech.) was more potent to white cell (WBC) counts and serum protein level. The present Haematological studies have disclosed the possible reaction of blood and blood forming organs to these insecticides.[1]
