How to use teaser rams
Natural breeding – introduce the teaser ram at a ratio of 1 ram : 100 ewes, replace the teaser after 14 days with fertile rams at ratio of 1 ram : 20 ewes. Most ewes will be served at either 18 or 25 days after the teaser is first introduced.
AI programmes – introduce the raddled teaser at sponge removal and leave with the ewes until they have all been inseminated.
Maiden ewes – maiden ewes that have been tupped by a teaser are easier to sponge. The teaser can be run with the ewes either during the previous autumn or three weeks prior to sponge insertion.
It is important that the maiden ewes are well away from the sight, smell and sound of any rams for at least 28 days prior to introducing the teaser. Remember to take the teaser out at sponge insertion. If the ewes are to be AI’d he can be re-introduced at sponge removal and left until all the ewes have been inseminated.
