[Cows with swollen anus and vulva as a husbandry problem].
An acute farming problem is described. The symptoms were poor intake of concentrates, swelling of the anus and vulva, and decreased milk production. Research results show that pig premix was incorporated into the concentrate for dairy cows. Which component of the concentrate was responsible for the symptoms remains to be established.
