The traditional weaning age of lambs is which of the following?

Weaning age is about when the lamb’s digestive system and feeding behavior are ready to switch from milk to solid feed without compromising growth. As lambs grow, their rumen develops enough to ferment forages and concentrates, and they need to eat enough non-milk feed to meet their energy and protein needs. Around twelve weeks (three months) many lambs are already consuming substantial solid feed and can sustain growth on forage and grain after separation from the ewe, so weaning at this time minimizes weight loss and supports continued growth. Weaning earlier, around two months, often means the lamb hasn’t yet built enough solid-feed intake and rumen capacity, leading to slower post-weaning growth or a temporary dip in performance. Weaning later, at four or five months, delays adaptation to solid feed, increases feeding costs, and can keep lambs dependent on milk longer than necessary. Traditional practice in many systems uses about three months because it balances readiness with practical management.
