Reevaluation Of Common Wheats From The Usda World Wheat Collection For Protein And Lysine Content, K. P. Vogel, V. A. Johnson, P. J. Mattern
Reevaluation Of Common Wheats From The Usda World Wheat Collection For Protein And Lysine Content, K. P. Vogel, V. A. Johnson, P. J. Mattern
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The protein and lysine content of wheat can be altered by breeding only if genetic variability exists for these traits. Lysine is a nutritionally limiting amino acid in wheat protein. Protein and lysine analyses of the common wheats of the USDA World Wheat Collection indicated that variability does exist for these traits. Some of the variability for protein and lysine among wheats of the World Collection may not be genetic in origin, because all the 12,000 wheats analyzed were not grown in the same environment. The purpose of this study was to reevaluate selected lines from the World Wheat Collection …

Results Of Systematic Analyses For Protein And Lysine Composition Of Common Wheats (Triticum Aestivum L.) In The Usda World Collection, K. P. Vogel, V. A. Johnson, P. J. Mattern
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Protein and lysine contents of 12,613 common wheats of the USDA World Wheat Collection were determined in order to identify wheats that may be sources of genes for high protein and high lysine. Results indicate that significant genetic differences in protein and lysine content probably exist among world collection common wheats. Selection criteria have been developed for further evaluation of World Collection lines high in protein and lysine content.

In order to elaborate all aspects of the sulfur problem in alfalfa production, a series of field, greenhouse and laboratory experiments was initiated to determine: 1. The influence of sulfur fertilization on the yield of alfalfa in Nebraska. 2. The influence of sulfur fertilization on the protein, vitamin A, and sulfur contents of alfalfa. 3. The sulfur supplying capacities of various soils under field and greenhouse conditions. 4. The sulfur content of precipitation at widely scattered points in Nebraska. 5. Soil properties associated with sulfur deficiency. 6. Optimum methods for estimating the sulfur status of soils by soil testing. The …

Historical Research Bulletins of the Nebraska Agricultural Experiment Station
1. The effect of replacing one-third of the concentrate of a ration for growing chicks with a mixture of starch and urea that contained an amount of nitrogen equal to that contained in the concentrate withdrawn from the ration was studied with two lots of chicks. 2. All chicks of both lots consumed equal amounts of nitrogen during the experiment. 3. Conclusions were based on increases in body weight and content of nitrogen, calcium and phosphorus at slaughter.

1. The effect of replacing the ten parts of alfalfa meal in a ration with artificially dried Sudan-grass meal on an equivalent protein basis was studied in a growth and body-analysis experiment with two lots of day-old chicks. 2. The chicks of both lots consumed equal amounts of dry matter during the feeding trial. 3. There were no significant differences in the growth rate or composition of the chicks at the end of a six weeks' feeding trial.

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 …

Studies Of Prairie Hay In North Central Nebraska, F. D. Keim, A. L. Frolik, G. W. Beadle
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
During five years, 1924-1928, Nebraska ranked first among the states in the production of prairie hay. Approximately 2,500,000 tons were grown annually during this period. In acreage utilized, wild hay ranked third among the field crops of Nebraska. As a forage crop in the state, prairie hay ranked first in acreage, but second to alfalfa in production. The purpose of this bulletin is to report studies made of the botanical structure and yields of the native hay meadows during a period of four years, 1926-1929, in the most prominent prairie hay producing section of the state. Four counties in this …

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 …
