Abstract
Blood parameters are an important index to assess the body homeostasis in mammals. Here, the effect of pesticide (imidacloprid) contaminated feed exposure on the haematological parameters of adult rabbits (n=15) was studied. Pesticides (Imidacloprid, Bildor® 0.5ml (100mg)/L water spray on vegetables and green grass) exposed feed fed to rabbits with wash (washed feed rabbit) or without a wash (not washed feed rabbit) in the once-daily morning for every alternative day up to 15 days. Control rabbits have received a standard diet (fresh vegetables and green grass). The blood cell analysis showed that the total erythrocyte count, packed cell volume, and haemoglobin values were not changed significantly in pesticide exposed rabbit. For differential leukocyte count, the percentage of neutrophil and eosinophil was significantly decreased in the pesticide-exposed rabbit as compared to the control rabbit. The lymphocyte percentage was increased significantly in pesticide-exposed rabbits compared to control rabbits. Interestingly, the number of lymphocytes was significantly increased in not washed feed rabbits compared to wash feed rabbits. The results of the present study suggest that residue of agriculturally used pesticides may affect the body homeostasis of animals.

Highlights
Blood is both a tissue and a fluid
Pesticide-exposed rabbits were again divided into two groups designated as not washed feed rabbit and washed feed rabbit
In the case of the differential leukocyte count (DLC), the percentage of neutrophil and eosinophil significantly decreased in pesticide-exposed rabbits compared to control rabbit (Table 2)
Summary
Blood is both a tissue and a fluid. It is composed of cells suspended in a fluid matrix (plasma) with the major function of maintaining homeostasis (Isaac et al, 2013). Blood parameters are good indicators of the physiological status of animals (Khan and Zafar, 2005). Blood parameters provide an opportunity to determine the presence of toxic metabolites and their constituents in the body, which plays a vital role in determining the body status of mammals (Etim et al, 2014). There is widespread evidence that most of the crop, vegetables, and fruit farmers in Bangladesh use pesticides (Miah et al, 2014; Kobir et al, 2020). The unregulated use and its aerial application over large agricultural and urban areas have caused severe threats to public health and animal health (Al‐Saleh, 1994)
