Upon signing up to the LambPlus service you will have indicated your intention to record by web or a paper service. Where breeders indicate that they will record through the Sheep Ireland web service (electronically), all performance data will be entered on the Sheep Ireland website Sheep Ireland have very few paper breeders, we recommend all new entrants to record electronically.

Where breeders choose the paper & postal based service then Sheep Ireland will provide all necessary recording sheets by post.

LambPlus member must submit a sign-up form signed and dated for the relevant year they are signing up. Existing members renewing their membership also must sign a renewal form and date it for the relevant year. Due to General Data Protection Regulation (GDPR) legislation introduced in Ireland in May 2018, Sheep Ireland need consent from all members (new and existing) of LambPlus every year to abide with these policies. Sheep Ireland will have no choice but to disable any LambPlus accounts that do not send in their signed and dated application form.

Inventory Update

Once breeders sign up it is necessary to provide a full inventory of the ewes and rams currently in the flock. It will be a minimum requirement to provide each animals NSIS tag, and pedigree information. Sheep Ireland host breed society flockbooks which will have the full pedigree information of all sheep in the flockbook. These breeds are using the Sheep Ireland database and Flockbook management system to help in the administration of their society. The breed societies currently availing of these services are: Texel, Belclare, Beltex,  Blue Texel, Charollais, Galway, Vendeen, Rouge, Irish Suffolks.

Breeders of sheep other than the breeds mentioned above will be required to manually submit the details of ewes and rams to Sheep Ireland. Sheets for these details will be forwarded to breeders once sign-up forms are submitted. A copy of pedigree certs can also be sent to Sheep Ireland in these cases.
