In a herd of 250 cattle, death rates as high as 44 percent were recorded from heifer groups; 27 of 30 parturient deaths were due to maternal dystocia. Significantly more male than female calves died of this cause. A trial using parenteral iodine established that goitre was not a contributing factor. The use of a Jersey bull for heifer matings eliminated the dystocia problem.
