Landraces sheep are native to Finland and are classified under the Finnish Northern Short Fat Sheep breed. These animals are known for their hardiness, adaptability, and high reproductive performance, making them a popular choice in various farming systems.
First, let's look at their physical characteristics. Rams typically have horns, while most ewes are hornless. They have a strong, well-proportioned body that is long and deep, though not very wide. Their bones are fine, and they have relatively poor belly hair coverage. However, what truly sets them apart is their exceptional reproductive ability. Ewes usually give birth to 2 to 4 lambs per litter, which makes them highly valuable for breeding purposes.
In terms of production performance, adult rams can weigh between 80 to 90 kilograms, while ewes range from 60 to 70 kilograms. The wool yield is impressive, with rams producing 2.5 to 4 kilograms of wool and ewes producing 2 to 3 kilograms. The fleece length ranges from 14 to 19 centimeters, with wool fineness measuring between 46 to 56 microns for rams and 44 to 58 microns for ewes. The wool is generally of good quality, with good luster, softness, and elasticity. The clean wool rate is between 64% and 75%.
The lambing rate of this breed is above 300%, meaning that on average, each ewe gives birth to more than three lambs per year. Under normal feeding and management conditions, lambs can reach weights of 32 to 35 kilograms by the age of five months. Due to their high fertility, Landraces sheep have been widely used in crossbreeding programs across more than 20 countries. Over 40 different breeds have been crossed with them, significantly improving the fertility of the resulting hybrids—from an average of 1.3 lambs per ewe to 1.9, representing a 40.7% increase. This makes the Landraces sheep an essential component in many livestock improvement initiatives worldwide.
