Applied Animal Nutrition-I

NUTRIENT REQUIREMENTS FOR WORKING BULLOCKS

• Work production normally does not involve extra protein over the maintenance. The requirement of nutrients for bullocks for work production is comparatively lower than for fast moving horses.
• For bullocks, the work has been categorized into 2 types
  • Normal work – working for 4 h of ploughing or 6 h of carting
  • Heavy work - working for 6 h of ploughing or 8 h of carting

• Nutrient requirements for working animals / head / day
• The nutrient requirements of bullocks for different types of work proposed by Sen (1978) and Ranjhan (1980, 1991) have been adopted by ICAR (1998).
