Cholinetrase concentration in the blood of three types of cattle raised on land exposed to Organophosphates

Abstract

Organophosphate pesticides are one of the causes of contamination in animal feed. The cholinesterase enzyme test is used to diagnose toxic exposure due to organophosphate pesticides. Quantitative research with cross sectional survey design used 35 samples of cattle. The study was conducted in March -September 2020. Concentration measurement on cholinesterase enzyme concentrations of blood plasma used the biosystem A15 DGKC-Colorimetric Kinetic method. This study aims to evaluate the concentration of the enzyme cholinesterase as a marker of organophosphate poisoning in cattle. Blood samples were collected from the ventrolateral neck veins of bulls and cows aged 1-7 years which collected from local breeders in the Ogan Ilir area. The results showed that the cattle raised on exposed land by organophosphate pesticides as concentration decreasing indication of cholinesterase enzyme in cows plasma. Cholinestrase enzyme levels in cows were 0.20 ± 0.067 U / ml and bulls were 0.27 ± 0.183 U / ml. The highest concentration of cholinesterase enzyme levels were occurred in cattle aged 2 years, 0.25 ± 0.34 U/ ml and the lowest was in cattle aged 7 years, 0.12 ± 0.04 U / ml.
