I. Basic Steps
A. Managing Ewe’s Health & Nutrition prior to and during pregnancy (gestation)
• Flushing used before breeding• Nutrition affects both the ewe and lamb
during pregnancy

I. Basic Steps continued
B. Identifying When Ewes Are Bred• Ram harness
• Chest paint
• Watch ewes for signs of heat (estrus)
• Check ewe’s udder for development late in gestation.
• Normal gestation length – 5 months minus 5 days, or 145 days

II. MethodsA. Pasture Lambing
– Ewe lambs in the field and does not come into the barn.
– Western Oregon– Cuts down on labor needed for
operation– Reduces chances of scours and
other bacteria infections– Increased chance of hypothermia
(cold lambs) & starvation.

II. MethodsB. Barn Lambing
• Intensive/High labor operation• Drop pens• Post lambing every ewe enters a small pen
(jug) for observation. • Higher incidence of scours & navel infection

II. Methods
C. Pasture to Barn Lambing• Moving ewe and lambs from pasture into barn
directly after lambing.
• Somewhat intensive management system
• Allows for a period of observation
• It’s a mix of the two other methods
