Later Mating Improves Lambing Results, R J. Suiter
Later Mating Improves Lambing Results, R J. Suiter
Journal of the Department of Agriculture, Western Australia, Series 4
Ovulation studies in Western Australia have indicated that increased lambing percentages in crossbred and Merino ewes could be expected from mating in February-April rather than December- January.
Such increases have been demonstrated in time of lambing trials with crossbred ewes, but had not been seen in Merino flocks until recently.
This report summarises the results of time of lambing trials with Merinos carried out at the Merredin and Wongan Hills Research Stations between 1963 and 1969.
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.
