Lamb Vigor Improves Lamb Survival

SheepNet Solution Turkey

Country: Turkey

Dairy or/and meat sheep: Dairy-Meat

Source of information: Scientific knowledge

Level of solution: Knowledge

Aim: To increase lamb survival by lamb vigor knowledge


  • Key note on lamb vigor scoring -colostrum intake efficiency, factors influence lamb vigor
  • It is highly correlated with the nutrition in the trimester of gestation, efficient nutrition for the ewe is very influential
  • PDF for stressors, Stress factors for the ewe has to be avoided during gestation for a better nutrition
  • Improved lamb vigor will increase survival


Expected benefits: less lamb loses in the neonatal period and attendance at birth

Prerequisites and/or limits (knowledge, training, capabilities, cost, management, facilities, equipment, etc.)

  • Farmers need to be aware for the gestation nutrition
  • Some ewes may need to treated differently during gestation
  • Poor BCS ewes produce lambs with less vigor at birth
  • Special time for gestation has to be allocated by farmer
