2. a term used to denote a group of dairy cattle housed together in a free stall system based on stage of lactation and production with string 1 being the most recently calved and the highest producing cows, usually containing cows to the time of peak lactation after which they would move to string 2 and subsequently later strings. This allows groups of cattle to be fed separately on the basis of production.
