The influence of alkaline earth metals on the distribution and excretion of strostium was studied in rats, sheep, and dairy cattle. The effects of dietary phosphorus and high levels of vitamin D on strontium distribution was observed. The influence of diuretics on potussium and cesium excretion was studied in sheep. Conventional and radiochemical procedures were used in studies of mineral metabolism in farm animals. Tracer studies are reported on copper- magnesium interrelationships in sheep; the calcium balance in sheep, swine, and steers as affected by stilbestrol, magnesium, ether extract, and zinc; and the relation of ccrtain blood plasma constituents to milk in the dairy cow. Studies of the effects of radiation on reproduction were continued in cattle, swine, and rats. Standard psychological tests were applied to pre- and post-natally irradiated rats in an effort to assess the effects of radiation on various behavior characteristics. An effort is being made to develop similar techniques applicable to farm animals. Clinical, hematologic, and opthalmologic examinations were continued on burros exposed to fission weapon neutron-gamma irradiation. One burro was exposed to gamma-neutron radiation from a critical assembly in order to provide blood fur sodium activation analysis. Levels were compared wath human vaiues due to accidental exposure. Preliminary studies were initiated to study the role of water in the radiosensitivity of dormant seeds. The program of seed and plant irradiation was continued with the irradiation of 25 samples.
