-
It is the only method at present of utilising frozen semen with good
conception rates.
-
Results in a shorter, more concentrated lambing time, which enables
breeders to be more accurate with feeding and management of ewes.
-
Allows access to genetics of animals that are no longer alive.
-
Allows breeders to access genetics of superior rams that are not
on the physical ram market.
-
By using frozen semen this reduces the risk of transferring diseases.
-
Offers ability to source genetic material on an international basis.
-
Offers extensive use of a superior ram which can be joined to 450
ewes on a single day.
-
Facilitates progeny testing of outside rams with minimal cost.
-
Facilitates progeny testing of homebred young rams.
-
Sheep on a rising plane of nutrition. Optimum body score of
2 - 3.
-
Sheep husbandry procedures should be performed at least 2
weeks before sponge insertion i.e. shearing, drenching, back lining
etc.
-
It is essential to keep the ewes isolated from the sight and
smell of rams until sponges are removed and the teasers are released
with the ewes.
-
Quiet, gentle handling of the ewes at all times. Dogs MUST be kept
to an absolute minimum.
-
The use of teasers at the ratio 1:10 has been shown to decrease the
period over which a group of ewes may ovulate.
-
Ewes should be weaned at least 6 weeks prior to AI
-
Maiden ewes should all have cycled naturally more than once before
being synchronised (maiden ewes have variable ovulation times hence
have varied conception rates)
-
Check body condition of ewes 6 weeks before AI. Ewes of score 2.5
to 3 are ideal. Ewes greater than this should be run tight to ensure
they are not over fat at the time of insemination.
-
Make sure AI area is clean and is protected from direct sunlight
and drafts.
-
For fresh laparoscopic AI, rams should be rested for at least 4 days
before AI.
-
Ewes should not be overfed following AI. Any change in diet or management
systems following AI should be avoided.
