The Herdbook

The Herdbook is there for you

The Swifter sheep herdbook was instituated in 1982, and it has grown rapidly since then. There still is much demand for good breeding material.

The aim of the Swifter sheep herdbook is to control the quality of its members’ breeding animals. Thus, there is a thorough breeding register by means of, among others, pedigree certificates, lists of all rams used in that year, who have an own breeding value for fertility and ewes with a high breeding value for fertility, tupping lists and offspring registers. Furthermore, estmated breeding values are determined according to the Best Linear Unbiased Prediction method (BLUP).

All production and breeding data are processed by computer.
