The development of modern technologies now allows thousands of genetic markers in an animal’s genome to be revealed by means of DNA genotyping. This information can be used to deduce genomic inbreeding. This is valuable for populations that have no, or only incomplete, pedigree information. Furthermore, differences in the inbreeding of full siblings can be demonstrated and it is possible to identify where in the genome the inbreeding has had an effect. In this way it provides clues to genetic diversity within a breed. In this study, genomic inbreeding was investigated for 1,120 sheep from eleven breeds and for 332 goats from ten breeds. An average genomic inbreeding > 6.25 % between individual animals was observed in the goat breeds Saanen (SA), Toggenburg (TO), Grisons Striped (BS), Valais goat (WZ), Appenzell (AP) and Stiefelgeiss (ST), as well as for the sheep breeds Valais Blacknose (SN), Spiegel (SPS), Roux du Valais (WLS) and Ouessant (OUE). In general, the consideration of genomic data allows a better understanding of kinship and inbreeding conditions in Swiss breeds and therefore enables better decision-making in relation to breeding and possible conservation activities.
Which stakeholders in the dairy sector have an influence on the productive life of dairy cows? Research results from FiBL and Agroscope suggest that broad-based cooperation is needed to create structures for a longer productive life.
Agriculture is aiming to reduce greenhouse gas and ammonia emissions. Agroscope showed that for dairy cattle housing, feed composition plays a role in these emissions as well as wind and temperature.

Tannin-containing feedstuffs like Acacia mearnsii and sainfoin (Onobrychis viciifolia) have a measurable impact in reducing methane emissions from dairy cows. However, since these feedstuffs in some cases lead to productivity losses, careful consideration must be given to their use.
