Bylaw Amendments

July 17, 2017

We are pleased to report that Jersey Canada has received Ministerial approval for the April 2017 bylaw amendments! The changes to Article 19 (Rules of Eligibility for Registration) and Article 20 (Registration) are now in effect. 

The bylaw amendments address three key areas:

  1. How we determine the eligibility of an imported animal;
  2. Updating Jersey Canada’s definition of a base animal;
  3. How we determine the purity level for progeny of ineligible sires and/or percentage dams. 

Imported Animals

Jersey Canada has an international reputation for high standards for purity levels in the bulls registered in our herdbook. These standards have not changed. The Jersey Canada constitution still requires that every registered male must be purebred. Our definition of purebred is a minimum 31/32 or 96.87% registered Jersey. With the amended bylaw, we have simply improved how we figure out if an imported animal is purebred by asking the question: “Are there no fewer than 31 of 32 registered Jerseys in the fifth generation of the pedigree?” 

Jersey Canada’s Rules of Eligibility for Registration are completely independent of all other national Jersey societies. Our rules do not consider an animal’s purity status in another country, and therefore we cannot guarantee that there is a direct link between the purity status of an animal in another country and their status in Canada. When a Jersey is imported into Canada, Jersey Canada staff will research the animal’s five-generation pedigree to determine its purity level in the Canadian herdbook. 

Base Animals & Percentage Animals

The amended Article 20 (Registration) now directly addresses the purity level of Jersey heifers sired by bulls which are not eligible for the Canadian herdbook, and defines the percentage purity assigned to Jersey females in Canada. The amendment to this bylaw now considers the purities of both parents. If a female is sired by a purebred Jersey sire and is out of a percent dam, then the calf’s percentage would be the simple average of the two parents. Similarly, if a heifer calf is sired by an unknown or otherwise ineligible bull, then her percentage would be the average of her dam’s percentage and 0% for the sire’s percentage. Daughters of ineligible bulls are no longer considered base animals, but instead “one step down from the dam. Base animals are those with both an unknown sire and unknown dam.
