Feeding trials were conducted on three groups of chicks in eight lots receiving a growing mash containing dehydrated alfalfa meal at levels of 2, 3, 4, 5, 6, 9, 10, 12, and 15 per cent. Comparisons were not made simultaneously but no general trend toward growth depression was evident in comparable lots. In addition duplicate trials of four lots of newly hatched New Hampshire chicks were made on pelleted rations carrying 0, 2, 4, and 6 per cent of a good quality dehydrated alfalfa meal. The chicks were all fed accurately known amounts of the pelleted rations for six weeks. …

I. The trypsin inhibitor contained in one-half of a lot of soybean meal was destroyed by autoclaving at 15 pounds for 20 minutes. 2. This portion of the meal when fed at a level of 24 per cent to newly hatched poults gave a significantly greater gain in five weeks than did an equal amount of meal in which the inhibitor had not been destroyed. 3. The difference in growth is attributed to the destruction of the trypsin inhibitor.
Trypsin Inhibitor. V. Nutritive Value Of Treated Soybean Oil Meal And Some Characteristics Of The Trypsin Inhibitor In Soybeans, Raymond Borchers, W. E. Ham, R. M. Sandstedt, C. W. Ackerson, R. H. Thayer, F. E. Mussehl

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 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 Influence Of Whole Wheat, Bran And Shorts On Body Weight And Feather Growth In Chicks, F. E. Mussehl, C. W. Ackerson, M. J. Blish
The Influence Of Whole Wheat, Bran And Shorts On Body Weight And Feather Growth In Chicks, F. E. Mussehl, C. W. Ackerson, M. J. Blish
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The proteins of the entire wheat kernel and of the bran and shorts are apparently utilized with equal efficiency by growing chicks when used with a base of corn, barley, oats, meat scraps, fish meal, and soybean meal. The relatively higher protein levels of bran and shorts, as compared to ground wheat, should be considered by the poultry producer in deciding which product or products can be used with greatest economy. A good concentration of a feather-growth factor is found in wheat bran. Other common feedstuffs carry the same essential, and the amount of bran which should be used in …

The Utilization Of Food Elements By Growing Chicks. Vi. The Influence Of The Protein Level Of The Ration On The Growth Of Chicks, C. W. Ackerson, M. J. Blish, F. E. Mussehl
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
1. Two rations containing 16 and 22 per cent of protein respectively were fed to newly hatched chicks in two series of feeding trials. In one series the lower protein level was secured by diluting the higher with 30 parts of starch so that the amount but not the quality of the protein was changed. In the other series the amount and quality of the protein both varied since the two rations were mixed by using different proportions of the base and concentrate to yield the 16 and 22 per cent levels in the finished rations. 2. Comparisons were made …
