Study on the Draughtability of Crossbred Bullocks and Their Physiological, Haematological Changes during Work Performance

The study was conducted for evaluation of draughtability of crossbred bullocks. A total of 4 crossbred bullocks, aged between 5 to 8 years were evaluated for draught performance. The draughtability of the bullocks was measured by estimating Overall Draught Ability (ODA) as per the method described by Thomas (1996) using modified single animal pneumatic-tyred cart (for carting ability) and single animal plough (for ploughing ability). The ODA value of 4 crossbred bullocks ranged from 55.13 to 61.04 with an average of 57.54 ±1.36. There was a significant (P< 0.01) increase in all the three physiological parameter as compared to their pre-work values. The findings indicate that after the completion of work, PCV, Hb and TEC decreased significantly (P<0.05) and TLC increased significantly (P<0.01).
