WITH normal late spring-early summer matings (October-December) teaser rams, correctly used, will give a more concentrated lambing.
This has been shown under Western Australian conditions in trials conducted at the Wongan Hills Research Station.
In one experiment a group of 100 ewes which had one per cent, of teasers for 14 days before the fertile rams went in, dropped 42 lambs in the first two weeks of lambing, compared with 17 lambs from 100 ewes that were not teased.
The use of teasers in all Research Station flocks is now routine practice.
