The project investigates the molecular causes of natural hornlessness in cattle. The mutation giving rise to polled cattle allows for homozygote polled animals to be determined with certainty and for genetically polled animals to be used efficiently in crossings.

Swiss Low Input Genetics (SLIG)
This project investigates the benefits of genome-wide sequencing data for the assessment of genomic breeding values in Swiss dairy cattle breeds. It is undertaken by HAFL in cooperation with partners in the industry and Iowa State University. In addition, a tool by which to monitor rates of inbreeding increase is being developed in order to safeguard genetic diversity in the long term.

Estimated breeding values for Swiss sheep
In the past, sheep were selected for breeding on the basis of appearance and performance. Nowadays, this system has been replaced with estimated breeding values. These values are being compiled for Swiss sheep by HAFL in collaboration with the Schweizerischer Schafzuchtverband (Swiss Sheep Breeders’ Association). So far, the following breeds have been considered: White Alp Sheep, Brown Headed Meat Sheep, Black Brown Mountain Sheep, Valais Blacknose Sheep and Engadine Sheep. Since 2009, the breeding values for the ‘daily growth rate to 45th day’ characteristic have been estimated, differentiating between the genetic growth potential of the lamb and the genetic potential for milk performance of the mother. On the basis of these two characteristics, animals can be bred to achieve both high daily growth and high milk performance. In 2012, the sheep breeders’ association decided to extend the existing estimated breeding values to include the ‘age at first lambing’, ‘between-lambing period’, ‘litter size 1’ and ‘litter size 2’ fertility characteristics.
