“…Sauter and Steelo (1972) have suggested pesticide residues as a major cause of declining population of several wild species of birds. Poultry may be exposed to pesticides either by ingestion of contaminated feed or through use of pesticides in poultry house (Foster, 1974). This study evaluates the effect of dichorvos on the reproductive performance of egg laying hens.…”

The effect of dichlorvos on reproductive performance of laying hens was studied. Seven weeks old pullets with an average weight of 557.5 ± 9.5 g were divided into four groups and fed ad libitum with commercial poultry feeds contaminated with 0.01, 0.02 and 0.04% dichlorvos (w/v). The group without dichlorvos served as the control. Exposure to dichlorvos was continued until nine weeks after the hens started laying eggs. There was a significant reduction (p<0.05) in feed intake between the control group and those exposed to dichlorvos. Egg laying was delayed in the hens exposed to the pesticide by as much as eighteen weeks. The ages of the hens at first egg lay were 18 weeks for the control, 23 weeks for hens fed on 0.01 and 0.02% contaminated diet and 36 weeks for those fed on 0.04% contaminated diet. The average daily egg production was reduced from 5 eggs in the control group to 1 egg in 0.04% contaminated group. The protein contents of the egg (yolk and egg-white) and cholesterol level of the egg yolk were lowered in birds exposed to dichlorvos. There was no significant difference in the weight of eggs between the control and those exposed to pesticide. Results of this study suggest that exposure of laying hens to dichlorvos could affect their reproductive success.

“…Despite the higher lethal action of organophosphates, these are being used increasingly in place of chlorinated hydrocarbons ( 6 ) . The latter pesticides persist longer in the body and lead to the development of resistance in insects (9). Poultry may be predisposed to organophosphate toxicity by ingestion of contaminated feeds or insects exposed to pesticides or by exposure to pesticides for the control of ectoparasites (9).…”

“…The latter pesticides persist longer in the body and lead to the development of resistance in insects (9). Poultry may be predisposed to organophosphate toxicity by ingestion of contaminated feeds or insects exposed to pesticides or by exposure to pesticides for the control of ectoparasites (9). Poultry can also be used as test animals because the neurotoxic effects of organophosphates in poultry are similar to those in man (9).…”

Summary The lipid metabolism changes due to acute and chronic toxicity of Metasystox‐R (0,0‐dimethyl‐S‐2(ethyl sulphinyl ethylthiophosphonate) and Lebaycid (dimethyl‐3‐methyl‐4‐methyl thiosphenyl phosphorothionate) have not been previously studied. The histopathological and lipid metabolism changes in brain, spinal cord, sciatic nerves, liver, kidney and thigh muscles of white Leghorn, male chicks caused by chronic toxicity due to Metasystox‐R and Lebaycid were, therefore, studied. Lebaycid and Metasystox‐R produced degenerative changes in the nerve fibres of the sciatic nerve and spinal cord, respectively. Conspicuous changes in muscles, characterized by hyalinization of myofibrils were observed. Degenerative changes in other tissues were also noted. Changes in levels of phospholipids, cholesterol and various classes of phospholipids occurred, including decreased levels of phospholipids in various tissues during both acute and chronic toxicity. During chronic toxicity there was a decrease in the ratio of phospholipids to cholesterol. The increased levels of cholesterol in the biomembranes predispose them to degeneration and confirmed the degenerative changes in liver, muscles and kidneys. The mode of action of these organophosphates on lipid metabolism is discussed. Zusammenfassung Histologische Veränderungen und Störungen des Lipidmetabolismus in Organen von Kücken (Gallus domesticus) bei akuter und chronischer Metasystox‐R‐ und Lebaycid‐Vergiftung Die Veränderungen des Lipidstoffwechsels bei akuter und chronischer Vergiftung mit Metasystox‐R (0,0‐Dimethyl‐S‐2(äthyl sulphinly äthylthiophosphonat) und Lebaycid (dimethyl‐3‐methyl thiosphenyl phosphorothionat) wurden bisher nicht untersucht. Bei weißen, männlichen Leghornküken wurden die histologischen Veränderungen und die Störungen des Lipidstoffwechsels bei chronischer Metasystox‐R‐ und Lebaycid‐Vergiftung studiert, und zwar an folgenden Organen: Gehirn, Rückenmark, Nervus ischiadicus, Leber, Niere und Schenkelmuskulatur. Die Gifte erzeugten degenerative Veränderungen an den Ischiadicusnerven sowie am Rückenmark. Die Myofibrillen zeigten eine Hyalinisation. Auch in den anderen Geweben waren degenerative Veränderungen festzustellen. Sowohl bei der akuten als auch chronischen Vergiftung kam es zu Veränderungen des Gehaltes an Cholesterin und Phospholipiden. Bei der chronischen Vergiftung verkleinerte sich der Phospholipid‐Cholesterin‐Quotient. Die Cholesterinvermehrung in den Biomembranen schaffen eine Prädisposition für Degenerationen, was in dei degenerativen Prozessen in Leber, Muskeln und Nieren zum Ausdruck kam. Der Wirkungsmechanismus der untersuchten Organophosphate auf den Lipidmetabolismus wird besprochen.
