Abstract
In utero exposure of neonates to pesticide residues could be damaging to the reproductive tract. Hence, the present study assessed the circulating concentrations of pesticide residues in buffalo and their neonatal calves as well as in the reproductive tract tissue samples of same calves. Also, histopathological alterations were revealed in the reproductive tract of calves. Pesticide residues were high (P < 0.05) in the reproductive tract of calves (119.5 ± 20.2 ng/g, 35% positive) in comparison to their blood (32.1 ± 8.4 ng/ml, 15% positive) or blood of their dams (41.5 ± 8.3 ng/ml, 25% positive). The number of histopathological alterations were high (P < 0.05) in the reproductive tract of a calf contaminated with high concentrations of pesticide residues (3.43 ± 1.29) in comparison to a tract positive for low residue concentrations (1.57 ± 0.60) or pesticide negative tract (0.28 ± 0.10). In conclusion, in utero exposure of neonatal buffalo calves to pesticide residues may be associated with damaging alterations in their reproductive tract.
