The Vitamin A And The Vitamin E Content Of Field-Cured And Artificially Cured Alfalfa Hay, I. L. Hathaway, H. P. Davis, R. R. Graves Oct 1932

The Vitamin A And The Vitamin E Content Of Field-Cured And Artificially Cured Alfalfa Hay, I. L. Hathaway, H. P. Davis, R. R. Graves

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

A comparative study of the vitamin A content of field-cured and artificially cured alfalfa was made by comparing the growth produced by 124 rats receiving alfalfa hay as their source of vitamin A. From the results of this study, in which the experiments were duplicated, it is concluded that under the conditions of these experiments the artificially cured alfalfa was twice as potent in vitamin A as was the field-cured alfalfa. The comparative study of the vitamin E content of these hays was made by comparing the number of litters produced by groups of female rats which received graded quantities …

Utilization Of Proteins By The Growing Chick, F. E. Mussehl, C. W. Ackerson May 1931

Utilization Of Proteins By The Growing Chick, F. E. Mussehl, C. W. Ackerson

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

1. There is a marked difference in the nutritive value of the various protein-contributing concentrates when used to supplement a corn-wheat basal ration which has been made complete for known vitamin and mineral essentials. 2. There is a great difference in the biological value even of animal protein concentrates. 3. Soybean meal produced a better growth rate than any of the other plant concentrates used. Cottonseed meal proved to have a greater growth-promoting value than did linseed oil meal. 4. The supplementing values of protein concentrates, one to another, is not quite as evident as one would expect if the …

The Vitamin A Content Of The Milk Of Holstein, Ayrshire, Jersey, And Guernsey Cows, H. P. Davis, I. L. Hathaway Feb 1931

The Vitamin A Content Of The Milk Of Holstein, Ayrshire, Jersey, And Guernsey Cows, H. P. Davis, I. L. Hathaway

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

A comparative study of the vitamin A content of milk produced by Holstein, Ayrshire, Jersey, and Guernsey cows was made by comparing the growth produced by 560 rats receiving milk from these breeds as their only source of vitamin A. The results showed some slight irregular differences in the gains produced by the milk from the different breeds. When these differences were considered in view of the individual variation of the experimental animals, they appeared negligible. This conclusion was substantiated by a statistical examination of the data. From the results of this study in which the experiments were duplicated, it …

Nutrient Requirements Of Growing Chicks, F. E. Mussehl Dec 1926

Nutrient Requirements Of Growing Chicks, F. E. Mussehl

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The object of our experimental work was to establish if possible certain principles of poultry nutrition, permitting later a better combination of natural feedstuffs with the highest growth efficiency.
