Singh, R C | Singh, C D
The relationship among the draught capability, and work output in relation to the age and body weight was studied for the Malvi and crossbred (Jersey and Red Sindhi) oxen. A critical age group of 4.5 _ 12 years has been identified for the animals to derive the maximum work output. The draught ability of Malvi breed of bullock was higher as they produced maximum work output. The draught ability of Malvi breed of bullock is higher and produced maximum work output of 1.5_1.62 kWh at draught load equivalent to 12% of their body weight as compared to crossbred bullocks. The maximum work output of crossbreed oxen is 1.32 _1.44 kWh at draught load equivalent to 10% of their body weight without fatigue. The energy required for metabolism varied from 5933.98 to7104.22 kcal/day for both breeds of bullock whiles the endogenous nitrogen consumption was from 11 080 to 13 270 mg.
