Nutrient requirements for maintenance of adult sheep

NUTRIENT REQUIREMENTS FOR MAINTENANCE OF ADULT SHEEP

Maintenance

  • Many experiments have shown that in sheep, consumption of 31 – 35 g of DCP / 30 kg body weight would show a positive balance and this comes to an intake of 2.73 g DCP / kg W

0.75. This figure has been taken for calculation of requirements for maintenance. In calculating the energy requirements for maintenance, 350 g of TDN for 30 kg b.wt has been taken as adequate. This comes to 27.3 g / kg W0.75 or 98 kcal ME / kg W0.75 (ICAR, 1998).
