Improved solution to increase fertility in high-yielding cows

Through decades, researchers have been able to increase milk production in cows by intense genetic selection. However, this has resulted in a reversal of the fertility of the cows. This has led the researchers to find an optimum solution.


Chromosomal deletion catalogue in dairy cattle facilitates the identification of lethal mutations

Genetic mutations are responsible for a substantial yearly-economic loss in the dairy industry. Mapping of such variants is essential for effective breeding planning and performance improvement.


The genes of the cow determine the health of the milk

Research from Aarhus University and SEGES shows that the genealogical tree has great impact on the quality of the cow's milk. This provides new opportunities for producing milk with specific properties.

Improved breeding value assessment for reproductive performance in dairy cows

The routine breeding value assessment for reproductive performance in Denmark and Sweden may be improved by means of activity-based fertility traits. This is demonstrated by results from a recently finished PhD project. In addition, it has been demonstrated that the genetic variation in reproductive performance changes in relation to calving season and production environment.

Breeding confident mink has side benefits

When you select for confident mink in the breeding programme, you also get a better fur quality according to a study from Aarhus University. The study also shows that behaviour has a higher heritability than previously though.

Important mutation discovered in dairy cattle

Scientists have discovered a mutation with a built-in dilemma for dairy cattle breeders. The deleted gene sequence has a positive effect on milk yield but causes embryonic death in dairy cattle.

Renaissance of the Danish "bacon pig"

The Danish Landrace 1970 – also known as the ‘Bacon Pig’ – has received a genetic boost. By using frozen semen, “old” genes have successfully been re-introduced to the breed. This has huge impact on the preservation of the breed.

Food shortage can be averted

We must use our planet’s resources better if we are to provide food enough for everyone in the future. One of the options is to use plant breeding to achieve higher crop yields. We must also reduce food waste and apply brakes to population growth if we are to ensure sustainable food security. AU scientists are ready to supply much of the knowledge that is needed.

Towards low-impact high-yielding cows

Burps, behaviour, blood and milk are some of the traits that can give us an indication of how efficient and eco-friendly a cow is. Scientists at Aarhus University are developing tools that can identify the most cost-effective cows. This will benefit the farmer’s economy and the environment.
