Reduced Ascorbic Acid Content Of Potatoes Grown With And Without Straw Mulching And Irrigation In Eastern Nebraska, H. O. Werner, Ruth M. Leverton, Mary R. Gram
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Potatoes harvested from home gardens and in commercial early-producing fields in the Midwest are an important low-cost source of ascorbic acid from late June into September. The major portion of the early commercial crop in Nebraska (harvested mostly in August) is produced with irrigation. Straw or litter mulching is a well established practice in the nonirrigated garden and farm potato patches. The value of these cultural methods for increasing yield is well known, but prior to this study little was known about their influence on the ascorbic acid content of the tubers, or about the persistence of any such influence …

The marked improvement in the apparent nutritive value of soybean protein after heating has long been recognized. The fundamental cause of this improvement has never been fully understood. Furthermore, commercial soybean oil meal varies considerably in nutritive value although heat treatment is common in most processing plants. Since heating is generally regarded as deleterious to the nutritive quality of protein, the following investigations of various treatments of soybean oil meal are of particular importance in developing a soybean or soybean oil meal of maximum and uniform nutritive value.

The Vitamin A And Carotene Content Of Nebraska Butter, I. L. Hathaway, H. P. Davis
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The vitamin-A, carotene, fat and moisture concentrations of Nebraska creamery butter were determined at monthly intervals for 25 months. Samples were obtained from 14 creameries located throughout the state. Their vitamin-A and carotene determinations were made with the aid of a spectrophotometer, and their fat and moisture analyses were determined by the A.O.A.C. methods. From a comparison of these data with the results of investigations in other states it was concluded that Nebraska butter was at least equal in vitamin-A value to average United States butter.

The Use Of Dried Whey And Blood Meal In The Raising Of Calves On Limited Amounts Of Milk, I. L. Hathaway, G. W. Trimberger, H. P. Davis
The Use Of Dried Whey And Blood Meal In The Raising Of Calves On Limited Amounts Of Milk, I. L. Hathaway, G. W. Trimberger, H. P. Davis
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The use of substitutes for milk in the raising of calves is always of interest to the progressive dairyman, since there are a number of circumstances in which it is advantageous to reduce the milk feeding period. Producers of market milk often desire to raise their calves on as little milk as possible in order to have more milk available for market. When the demand for milk is good, dairymen who usually market cream only may prefer to sell milk and raise their calves on starters or other milk substitutes. Dairy farmers may wish to use the skim milk generally …
The Vitamin A Content Of Soybean Silage And Of A.I.V., Molasses, And Common Corn Silages, And The Effect Of Feeding These Materials Upon The Vitamin A Content Of Milk, I. L. Hathaway, H. P. Davis, J. C. Brauer
The Vitamin A Content Of Soybean Silage And Of A.I.V., Molasses, And Common Corn Silages, And The Effect Of Feeding These Materials Upon The Vitamin A Content Of Milk, I. L. Hathaway, H. P. Davis, J. C. Brauer
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
A study was made of the vitamin A content of soybean silage, and of A.l.V., molasses, and common corn silage. The silages were fed to groups of cows and the vitamin A content of their milk determined. The vitamin A determinations were made by feeding the silage or the milk to groups of rats whose body stores of this vitamin had been depleted by being fed a vitamin-A-deficient ration. Approximately 780 rats were used in these experiments. There were no apparent ill effects of feeding as much as 3.2 grams of the A.l.V. silage per rat per day for eight …

The Vitamin A Content Of Skimmilk, Standardized Milk, And Cream From Different Breeds Of Cows, I. L. Hathaway, H. P. Davis
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
A study was made of the vitamin A content of skimmilk, of milk standardized by the addition of separated milk, and of cream. Rats whose body stores of vitamin A had been depleted by being fed a vitamin A deficient ration were fed either skimmilk, standardized milk, or cream as a source of vitamin A. Approximately 750 rats were used in nine experiments. From the results of these experiments the following conclusions were drawn: (1) that the vitamin A content of milk is associated largely with the butterfat and that separated milk containing a small quantity of fat contains only …

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
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 …
