Progress is reported in the following studies: factors affecting dwarfism and the inheritance of this trait in beef cattle; the effects of magnesium deficiency on Mg/sup 28/ metabolism in sheep; the effect of excessive dietary calcium on the uptake of Se/sup 75/, Mo/sup 99/, Cu/sup 64/, and Fe/sup 59/ in swin e; tracer studies on the binding sites of calcium and strontium in swine; tracer studies on cesium and potassium metabolism in lactating dairy cows; an ultrafiltration study on stable and radioactive calcium and phosphorus levels in milk and blood plasma in lactating cows; the influence of dietary calcium, phosphorus, and magnesium on the body weight and uptake of Ca/sup 45/, P/sup 32/, and Sr/sup 89/ by the tibiae o f chicks; the distribution of Ca/sup 45/, Sr/sup 89/, and Ba/sup 133/ in the eggs and various protein fractions of hens; the binding of Mo/sup 99/ by proteins in plasma, liver, and kidney of chicks; the effects of radiation on the reproductive physiology in rats, observations on the physical state of burros exposed to combined neutron and gamma irradiation or to gamma radiation or neutron irradiation alone; the status of swine surviving combined gamma -neutron irradiation from atomic detonations; the physical condition and determination of LD/sub 50///sub 3/0>svalues>i for irradiated adult female Hereford cattle; the physical condition of cattle exposed to radioactive fall-out from the first atomic test at Alamogordo, New Mexico, July 16, 1945; the survival and physical condition of calves exposed to 550 r total-body Co/sup 60/ gamma radiation with supportive therapy; investigations of the physiological effects of radiation in domestic animals; the radiosensitivity of seeds; the effects of pre and postradiation humidity and species on the radio sensitivity of seeds; the transmission of radiation-induced mutations in plants; factors affecting the diffusion of P/sup 42/ Ca/sup 47/, and Sr/sup 85/ in soils; and the development of a procedure for bone-density measurements.
