The Finnish Landrace breed
and their crosses has been the most studied sheep breed in the world over the
last quarter century. Here is a list showing a sample of the studies which have
been conducted and published. The Maijala article quoted on the Home page
summarises 120 such papers from 10 countries.The conclusion of all this
research is that 1/2 Finnish Landrace crosses will increase the following
traits as compared with the breed being crossed with by the following amounts:
percentage of multiple births +328%, Litter weight weaned/ewe weight +125%,
lambs born/ewe/year +141%, Lambs slaughtered/ewe/year +139%, lambing difficulty
score -87%.
