Product Description

Regulin; improves the reproductive performance of pure bred and crossbred lowland sheep which are to be mated early in the season before the usual peak of reproductive activity.

When used as directed, it stimulates the early onset of natural reproductive activity, giving improved reproductive performance of flocks mated early in the season.

Regulin; is recommended for use in Suffolk and Suffolk cross type flocks intended to start lambing between early December and mid January and in Mule and halfbred flocks starting lambing between late December and mid February.

Pack includes 3 needles

Dosage & Administration

One implant per ewe by subcutaneous administration at the base of the ear.

Use the implanter to administer one implant near the base of the ear.

In Suffolk and Suffolk-cross types, the implant should be used from mid-May to late June for ram introduction in late June and July.  In Mule and half-bred flocks it should be administered from early June to July for ram introduction from mid-July to late August.

Do not use at times other than those recommended. Do not administer if sheep are wet or dirty.

Treatment regime:
Day 1 (30 weeks before intended start of lambing).

As the presence of any ram (and also male goats) will interfere with the ovulatory process, isolate ewes from all males.  The ewes should be out of sight, sound and smell.  Separating males into the next field from females is not adequate.

Day 7:
Implant ewes at the base of the ear. Do not administer if sheep are wet or dirty. Ewes must remain isolated from male sheep and goats.

Day 42 (35 days after implantation):
The period between implanting and introduction of the males must be not less than 30 days and no more than 40 days.  Introduce rams, but expect a delay of 14-21 days before mating activity commences.  Vasectomised rams may be used for the first 14 days to ensure a more compact lambing period.  The peak of mating activity will occur 25-35 days after introduction of the rams.
