Effect of Pre-planting Seed Dressers on Serum Enzymes of Laying Chickens

The study was conducted to assess toxicity of synthetic insecticides in chickens. Twenty-five week old Nera black pullets (n=48) were fed with pre-planting insecticide-treated diets at recommended doses (T1=control, T2=2 g dressforce /Kg grains, T3=2.5 g apronstar /Kg grains, T4=2.5 g seedrex /Kg grains) for 14 days. Serum enzymes were assessed using standard procedures. Each treatment had 3 replicates. Data were analysed using analysis of variance at α0.05. Serum enzymes were significantly (P=0.05) elevated for aspartate aminotransferase (AST), alanine aminotransferase (ALT) alkaline phosphatase (ALP) for treatment diets. No mortality was recorded throughout the period of the experiment. Synthetic insecticides used resulted in liver dysfunction of chickens. Hence, alternative cheap bio-insecticides should be sourced.
