Feeding Late Gestation Ewes

     Feeding and feeding management of late gestation and lactating ewes is vital to the survival and rapid growth of lambs.  the last four to six weeks of gestation are critical in the ewe's production cycle .  The fetus gains about two thirds of its weight in the last 6 weeks of gestation.  Ewes that carry multiple fetuses have particularly high nutrient requirements.  To ensure that ewes maintain a body condition score (BCS) of 3 to 3 1/2 and gain weight during late gestation, supplemental protein and energy must be fed.  This grain feeding is also importat to help prevent vaginal prolapse and pregnancy toxemia.

     The time to start feeding late gestation ewes additional grain and protein depends on the body condition of the ewes, the anticipated lambing rate and past experience.  As a general rule, flocks with lambing rates of 130% to 175%, should start 3-4 weeks prior to the start of lambing.  Flocks with lambing rates of 180% to 225% must feed grain 4-6 weeks prior to the start of lambing.  Flocks with lambing rates of 180% to 225% must feed grain 4-6 weeks prior to the onset of lambing.  Feed ewes with multiples separate from those with singles.

  1. late gestation ewe lambs - 0.5 to 0.8 kg / ewe/ day
  2. late gestation ewes - 0.25 to 1 kg / ewe / day

     Over conditioned ewes (body condition score 4 and greater) can be fed 10% less grain per body condition score.  Under condition ewes (body condition score less than 3) can be fed 10% more grain per body condition score.
