Nutritional Management by Litter Size for Ewes

Nutritional management tailored to litter size significantly improves ewe productivity and lamb survival. Energy requirements rise by 40% for singles, 60% for twins, and 70% for triplets in the final six weeks of pregnancy. Concentrate feeding recommendations vary by litter size, with quads requiring up to 1.0 kg/ewe/day in the final week. Grouping ewes by litter size enables optimal supplementation, supporting adequate colostrum, higher birth weights, and reduced lamb mortality.
