The feasibility of the castration of piglets under local anaesthesia was investigated in a breeding herd during one year. None of the roughly 700 one to two weeks old piglets showed signs of side effects after the injection of 0.5 ml 2% lidocaine into each testicle. The extra time needed for handling the piglets and injecting the local anaesthetic amounted to about the time used for castration without local anaesthesia. In order to test the efficacy of local anaesthesia, one testicle only was injected in 156 piglets, and the intensity of vocalization was recorded when the two spermatic cords were severed about ten minutes after the injection. No vocalization, cries indistinguishable from cries of anxiety and shrill cries indicative of acute pain were recorded in 66, 24 and 10 per cent respectively when the testicle with the injected anaesthetic was removed and in 14, 50 and 36 per cent when the testicle without anaesthesia was removed. The study shows that local anaesthesia as described above is easy to perform and in general reduces the pain experienced during castration, although in at least ten per cent of the cases pain reduction is insufficient.
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.
