	abstract = {Milk responses to selenium supplementation were measured in 12 dairy herds of low selenium status as indicated by blood selenium concentrations of less than 150 nmol/l (<12 ug/l). In 4 of the herds milk responses were measured for 2 successive seasons. Milk volume responses to selenium varied from -2.6\% to +10.4\% (mean +4.6\%) and milk fat responses from -4.0\% to +10.2\% (mean +3.7\%). Significant (P<0.05) milk volume responses occurred on 2 farms in the first season and milk fat responses on 2 farms in the second season. A negative relationship (P<0.01) was found between milk fat response (\%) to selenium (FatSe) and blood selenium concentration (nmol/l) (BSe) for herds in their first season of supplementation of:- FatSe) = 9.6 - 0.059 BSe. There was no relation between these parameters in the second season of supplementation.},
