High Pre-Mating Liveweights Improve The Lambing Performance Of Merino Ewes, R J. Suiter
High Pre-Mating Liveweights Improve The Lambing Performance Of Merino Ewes, R J. Suiter
Journal of the Department of Agriculture, Western Australia, Series 4
Analysis of lambing trials with Merino ewes has shown a highly significant association between pre-mating liveweight and lambing performance.
With May-June lambing ewes there was a 2.9 per cent, lambing increase for every extra 10 lb. liveweight; for July-August- September lambing ewes there was a 6.9 per cent, increase for every 10 lb. liveweight increase.
With the May-June lambing there was a critical weight below which twinning was negligible.

Lambing percentages depend partly on the condition of ewes at mating. If it is practicable, ewes should be allowed to gain condition in the months before mating.
Where this is not practical and ewes are in a store or backward-store condition at mating, flushing should improve their fertility.
