Carotene Content Of Native Nebraska Grasses, I. L. Hathaway, H. P. Davis, F. D. Keim
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The carotene content of twenty-four grasses native to Nebraska were determined at approximately monthly intervals from June to November. While the carotene concentration of most of the grasses was moderately high during the growing season, it declined to a rather low point by late November. With the exception of Switchgrass, Hairy Grama, Little Bluestem and Prairie Dropseed, all of the grasses contained enough carotene to supply the needs of range cattle until late November. However, only eighteen of the grasses still contained enough carotene by the latter part of September to furnish the carotene required by dairy cows. Even as …
The Effects Of Penicillin On E. Rhusiopathiae Infected Pigeons, L. Van Es, J. F. Olney, I. C. Blore
The Effects Of Penicillin On E. Rhusiopathiae Infected Pigeons, L. Van Es, J. F. Olney, I. C. Blore
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Advantage was taken of an opportunity to study the effects of penicillin on Erysipelothrix rhusiopathiae, the causative organism of swine erysipelas. Owing to the fact that swine cannot readily be infected with erysipelas by artificial methods, pigeons which are highly susceptible to the disease, were selected to serve as experimental animals. It was the purpose of these studies to ascertain whether or not the swine erysipelas bacillus is sensitive to the drug and incidentally to determine the possibility of finding application of penicillin in the treatment of swine.
