Abstract
The objective of the study was to assess the potential benefits of using real-time ultrasound scanning in a hill sheep flock where the incidence of twinning is low. A high hill hirsel of some 320 Scottish Blackface ewes, typically lambing in the range 0.6-0.9 lambs per ewes mated, was divided across age into two groups. One group was scanned, colour marked and subsequently managed according to foetal number (the SCANNED flock). The other group was also scanned but not colour marked, and therefore managed irrespective of foetal number (the UNSCANNED flock).
