Exercise yards for dairy cows
The required area per cow depends on the use of the exercise yard. If all the cows are forced to go out at a certain time and if they are fed in there, an area between 5 and 10 m² per cow is needed. But if there is no feeding and the cows have free access to the yard only 4-5 m² per cow is needed. It is recommended to design the yard so that the area covered with soft material can be blockaded when ever it gets too wet. The design of sloping has to be very careful. The laboratory tests have shown that with filters consisting of straw, peat or woodchips it is possible to significantly lower the nutrient content of runoff waters
Exercise yards in Finland - structures and environmental impact
Two exercise yards have been designed, constructed and monitored. Samples from the runoff water have been taken regularly, and their nutrient concentrations(nitrogen, phosphor), total solids, pH, total chemical oxygen demand and hygienic quality have been analysed. The behaviour of animals has been observed

Pidä silmällä pihattojen ritiläpalkkeja
Suomessa vanhimmat pihatot ovat runsaat 20 vuotta vanhoja. Niiden ritiläpalkit alkavat vaurioitua jo 10 käyttövuoden jälkeen. Vuosina 1989-1999 maassamme sattui noin 60 tapaturmaa, jotka johtuivat ritiläpalkkien rikkoontumisesta. Ne pitäisi tutkia säännöllisesti, jotta vältytään ikäviltä onnettomuuksilta.vo
