BOZEMAN—Northern Great Plains cattlemen, in general, can expect breeding cattle to run on the range without protein, vitamin, or mineral supplements and still show good performance without developing a shortage of nutrients.
This is one of several experimental results published in a new Montana Agricultural Experiment Station Bulletin, "Nutrition of Cattle on Eastern Montana Range."
The bulletin reports the results of a 5-year study of the relation of soil nutrients, forage nutrients, and nutrition of Hereford cows at the U. S. Livestock Experiment Station near Miles City.
Cattle tested were grazed or pastured on three grazing intensities—heavy, moderate, and light. Several analyses were taken of soils for nitrogen and phosphorus; of forage plants for protein, phosphorus, and carotene; and of cow's blood plasma for phosphorus, calcium, magnesium, carotene, and vitamin A. General condition, weight, and reproduction of cows was also recorded, as well as weather conditions.
Copies of the bulletin are now available at county extension offices.

Story Details
A 5-year study at the U.S. Livestock Experiment Station near Miles City examined soil nutrients, forage nutrients, and nutrition of Hereford cows under heavy, moderate, and light grazing intensities. Analyses included soils for nitrogen and phosphorus, forage for protein, phosphorus, and carotene, and cow blood plasma for phosphorus, calcium, magnesium, carotene, and vitamin A. Cow condition, weight, reproduction, and weather were recorded, concluding that cattle can perform well without protein, vitamin, or mineral supplements.
