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

Nebraska Agricultural Experiment Station: Historical Research Bulletins

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

Nebraska Agricultural Experiment Station: Historical Research Bulletins

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

Nebraska Agricultural Experiment Station: Historical Research Bulletins

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.
