The ultrasonic scanning technology has provided farmers with a
useful tool to determine potential lambing percentages well in advance
of lambing. This paper outlines ways in which this information can be
used to effectively target groups of ewes to maximise feeding
efficiency. Underfeeding of the ewe flock can be partly alleviated by
the early sales of non-pregnant ewes. Understanding the interactions
between body condition and feeding in conjunction with scanning can
lessen birthing problems through appropriate feeding regimes. Targeted
feeding plans can ensure that both protein and energy needs are met for
single, twin and triplet bearing ewes. Feed types such as brassicas,
silage and grain can be targeted to specific periods throughout the
pregnancy for optimal feed use once parity is known.
