	abstract = {Iodine (I) concentrations in New Zealand pastures are low and may be  inadequate to meet the I requirements of lactating dairy cows. A trial was  undertaken with 400 cows to determine the effects of a single intra-muscular  injection of 2000 mg I (in popyseed oil) given at the beginning of lactation  on cow performance. The pasture I concentration ranged between 0.17-0.26  mg I/kg DM during of the trial and the supplement increased serum  thyroxine (T4) and milk I concentrations for 76 (P<0.05) and 170 (P<0.01)  days respectively. Iodine supplementation did not affect milk yield milk  composition or number of services per conception. To increase I status and  maintain milk I concentrations at or above 40 },
