The Utilization Of Nitrogen, Calcium, And Phosphorus By The Growing Chick, C. W. Ackerson, M. J. Blish, F. E. Mussehl

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

1. The nitrogen, calcium, and phosphorus content of 127 newly hatched chicks was determined. 2. Thirty newly hatched chicks were fed accurately known amounts of a good chick mash for 60 days. At the end of the period nitrogen, calcium, phosphorus, and fat were determined for each chick. 3. By means of the comparative slaughter test the retention of nitrogen was found to be 37.8 per cent, calcium 43.4 per cent, and phosphorus 27.3 per cent of the respective elements fed. 4. The average gain in live weight per gram of nitrogen fed was 12.0 grams. 5. The rate of …


The Vitamin A Content Of Sour Cream Butter, Sweet Cream Butter, And Margarines, I. L. Hathaway, H. P. Davis Aug 1935

The Vitamin A Content Of Sour Cream Butter, Sweet Cream Butter, And Margarines, I. L. Hathaway, H. P. Davis

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Nineteen samples of margarine were obtained from Illinois, Ohio and Nebraska. They were analyzed chemically and the vitamin A content of each one was compared with that of either sour-cream or sweet-cream butter. The fat content of the butter samples varied from 80.2 to 81.5 per cent, while the fat content of the margarine samples varied from 78 .3 to 89.2 per cent. From the results it was evident that these samples of margarine were very poor sources of vitamin A when compared with butter. One of the margarine samples caused an average gain of 10 grams per rat and …


Sales Value And Assessed Value Of Nebraska Farm Land: 1921-1934, Eleanor H. Hinman Jul 1935

Sales Value And Assessed Value Of Nebraska Farm Land: 1921-1934, Eleanor H. Hinman

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

How to secure just and equitable estimates of the value of farm land as a basis for taxation has always been a vexatious problem. The existing assessment law in Nebraska went into effect April 1, 1921. The present study attempts to show how the assessed valuations of farm real estate made under that law compare with the actual sales value of the farms sold during the 13 years ending March 31, 1934. The data used in this study include records of 35,753 tracts of farm land in 93 Nebraska counties sold during the 13 years ending March 31, 1934.


A Study Of Farm Families And Their Standards Of Living In Selected Districts Of Nebraska 1931-1933, Margaret Fedde, Ruth Lindquist Jul 1935

A Study Of Farm Families And Their Standards Of Living In Selected Districts Of Nebraska 1931-1933, Margaret Fedde, Ruth Lindquist

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This study of farm families in selected districts of Nebraska was undertaken in order to obtain information regarding the total money value of family living and the proportion of the total used for each of the principal groups of goods. A further purpose was to measure the adequacy of the living provided. The study was begun in January, 1931, and continued through the year 1933. The districts selected included Cass and Fillmore counties throughout the three-year period, and to these Buffalo county was added at the beginning of 1932.


A Key To The Nebraska Cutworms And Armyworms That Attack Corn, Don B. Whelan Jun 1935

A Key To The Nebraska Cutworms And Armyworms That Attack Corn, Don B. Whelan

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The following key to the Nebraska cutworms and armyworms injurious to corn is based upon structural characters supplemented in some instances by color. Not all of the species in this key have been found in Nebraska; some are included because they are to be found in near-by states to such an extent that they probably are present in this state.
