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
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 …
