This spring has been a blessing when you consider the weather experienced 12 months ago. Ewes are reported as being in pretty good condition and carrying a favourable crop of lambs. The success of getting live lambs on the ground and keeping mortality below 8% in lower litter size flocks and under 10% in higher prolificacy flocks will be influenced by preparation in advance of lambing. Ewes lambing down with lots of colostrum and vigorous lambs that are up quick to suckle is the ideal scenario. The chances of this occurring are influenced by late-pregnancy feeding and this is emphasised across a number of articles.
In this Focus, we the importance of good-quality colostrum, highlighting target intakes and differences in production across and within breeds. We also touch on the importance of feeding in ensuring favourable lamb liveweights and colostrum production for multiple litters.
