Sexual difference in chicken blood parameters during high ambient temperature

The present study was carried out to record the status of different blood and serum biochemical parameters of White Leghorn chicken at high ambient temperature. A total of 18 birds (9 birds of each sex) of 20 weeks age were used in the study. The heterophil: lymphocyte (H:L) ratio indicated that the birds were experiencing heat stress due to high ambient temperature. Significant difference was observed between the sexes in haemoglobin, total erythrocyte count, heterophils, H:L ratio, calcium and lipid peroxidation levels. Results of this study revealed that high ambient temperature induces stress that affects the sexes differently in chicken as evident from their blood profile.
