Abstract
The effect of the insecticide Methomyl and the ethanolic extract of comphor leaves on egg production of poultry chickens Gal/us domesticus and its shell characters was studied. Results showed that LD50 was 3.98 and 2.44 mg/kg b.w. for Methomyl and comphor extract respectivly. When femals treated with '1~ LDso of both compounds during (Two weeks) immature stage, results indicated that, the two tested compounds delayed oviposition of the first egg. Weight of eggs laid by treated females significantly decreased, while non significant changes were induced in the external features of egg diameter and egg shell. The adverse effect of these treatments on yolk and albumin parameters was obviously noticed in case of methomyl treatment in comparison with camphor extract. In the same time levels of phosphorus, calcium and magnesium in egg shell did not significantly affected with treatment of both compounds, while albumin total protein and total lipid in yolk exhibited a rather response to these treatments.
