Nutrient requipments for growing lambs

NUTRIENT REQUIREMENTS FOR GROWING LAMBS

Growth

  • A growth rate up to 200 g/day has been obtained in some experiments. Hence, the data was tabulated up to growth rate of 200 g/day.
  • The weaning weight of lambs varies from 10 to 25 kg depending upon the breed and feeding regimen during pre-weaning period. Therefore, the growth requirements have been given for lambs ranging in body weight from 10 to 30 kg.
