Agricultural factors affecting the radionuclide foodchain pathway: green forage consumption of dairy cows

Abstract

The fraction of feed obtained by dairy cows from green forage is important in calculating dose from /sup 131/I because of its short half-life (8 days). The U.S. Nuclear Regulatory Commission recommendations concerning feed consumption refer to experimental work done 15-20 years ago. The fact that the average milk production per cow has increased by 45% in the past 15 years suggested an accompanying increase in food intake and a need to reexamine the forage consumption parameters. In the present study records of the Dairy Herd Improvement Association were compared with experimental values and with recommendations by standard nutritional authorities. Results are presented in tables. As measurements of pasture consumption were not available an indirect estimate of green forage consumption was made using various assumptions which are discussed in detail.
