Haematology and behaviour of pullets transported by road and administered with ascorbic acid during the hot-dry season.

Abstract

The effects of ascorbic acid (AA) on pullets transported by road for 6h during the hot-dry season were investigated. Forty Shika Brown pullets administered orally with AA just before transportation served as experimental, while another 40 pullets given sterile water only served as control. Blood samples analyzed before and after transportation in control pullets showed a decrease (P<0.05) in packed cell volume and haemoglobin values, and a significant (P<0.05) increase in the values of heterophil/lymphocyte ratio, total protein and basophil counts post-transportation. In experimental pullets, the post-transportation values were not different (P>0.05) from those obtained pre-transportation. The result showed that the transportation was stressful in control pullets. The behavioural activities of the pullets' post-transportation period indicated that AA facilitated the transition of the state of depression that followed excitation back to excitation immediately after transportation. In conclusion, AA administration ameliorated the adverse effect of road transportation stress during the hot-dry season.
