uPIGLETS suffer just as much stress from being given iron orally as by injection, with most stress coming simply from being handled. Work at ADAS Terrington, Norfolk, shows that handling piglets increased stress levels, masking the impact of the chosen method of giving iron to prevent anaemia, explained researcher Richard Wynn.

Treatment, given during the seasonal infertility period, needs more research, but potentially has a role in controlling the problem, said Royal Vet College PhD student Mandy Dawson. &#42
