The Utilization Of Food Elements By Growing Chicks. Viii. A Comparison Of Alfalfa Meal And Artificially Dried Sudan Grass Meal In Rations For Growing Chicks, C. W. Ackerson, M. J. Blish, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Research Bulletins

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.

Amount Of Underground Plant Materials In Different Grassland Climates, S. B. Shively, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

From the highlands of central Mexico entirely across the United States and northward into Canada extends the great midcontinental area of grassland. From this central mass, prairie extends westward across Wyoming into eastern Utah, and southwestward through northern New Mexico into northern Arizona. Other grasslands in the northwest cover most of southern Idaho, a part of northern Utah, large areas in eastern Oregon and Washington, and recur in British Columbia. The Pacific prairie occupies the Great Valley of California, and the Desert Plains grassland much of southern Arizona and New Mexico and southwestern Texas. Together they constitute the Grassland or …

The Effects Of Stinking Smut (Bunt) And Seed Treatment Upon The Yield Of Winter Wheat, T. A. Kiesselbach, W. E. Lyness

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The depreciating effects of bunt or stinking smut (Tilletia levis Kuhn and tritici [Bjerk.] Wint.) upon the yield and quality of winter wheat in Nebraska and many other states are well known. The practical control of this disease through seed treatment has also been established and is being extensively practiced by growers. At the time these experiments were initiated in 1923, formaldehyde was the most commonly used disinfectant, while copper carbonate was just gaining recognition following its introduction by Darnell-Smith in 1915. It has been the chief purpose of the investigations herein reported to study the relative merits of …

Effects Of Frequent Clipping On The Underground Food Reserves Of Certain Prairie Grasses, F. S. Bukey, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

A series of experiments in which true-prairie grasses were clipped at frequent intervals afforded excellent materials for a study of the effects of such treatment upon the food reserves. Two species of Andropogon, at present the most important dominants of true prairie, were employed. A series of quadrats on a north-facing slope in the Blemont prairie in Lincoln, Nebraska, in which little bluestem Andropogon scoparius, grew in about 70 of big bluestem, A. furcatus, were obtained about a mile distant from virgin lowland prairie near the flood plain of salt creek.

Fifty Years Of Achievement In Agricultural Investigation, R. T. Prescott

Nebraska Agricultural Experiment Station: Historical Circulars

In Nebraska, a hustling frontier state in 1887, the legislature hesitated not at all in taking advantage of the provisions of the Hatch Act, and now that fifty years have elapsed since the Station was founded, seventy-five years since the Land Grant College Act was passed and the U. S. Department of Agriculture established, and almost twenty-five years since the Agricultural Extension Service was added, it seems worth while to present a general summary of achievement within the state. The main object will be to show some of the important things that have been learned through the investigations of the …

The Utilization Of Food Elements By Growing Chicks. Vii. A Comparison Of Corn And Kalo In A Ration For Growing Chicks, C. W. Ackerson, M. J. Blish, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Research Bulletins

1. The effect of replacing 31 per cent of ground corn in a ration by 31 per cent of ground kalo was studied in a growth and body-analysis experiment with two lots of newly hatched chicks. 2. The amounts of feed consumed by all chicks of both lots were kept identical by hand-feeding equal amounts of the pelleted rations daily. 3. There were no significant differences in the growth rate or composition of the chicks at the end of a six weeks' feeding trial.

Major Changes In Grassland As A Result Of Continued Drought, J. E. Weaver, F. W. Albertson

Department of Agronomy and Horticulture: Faculty Publications

A comprehensive research on 135 large tracts of prairie was completed in 1933 after five years of study. These tracts were distributed over an area of 60,000 square miles, including the eastern one-third of Nebraska, the western one-third of Iowa, and adjacent areas in the four neighboring states (2). This investigation furnished the background for an understanding of the profound changes which have occurred during the several years of the great drought, which first became pronounced in 1934. The response of prairie to the drought of that year has been discussed (3). Likewise, a detailed account of the destruction caused …

Effect Of Frequent Clipping On Plant Production In Prairie And Pastur, J. E. Weaver, V. H. Hougen

Department of Agronomy and Horticulture: Faculty Publications

The degeneration of native bluestem prairies of eastern Nebraska occurs slowly under moderate grazing or slight overgrazing but within two to five years where overgrazing is pronounced. Although the changes in the plant populations are continuous until the soil is finally almost bare, for convenience of study they have been grouped into several more or less distinct stages (Weaver and Harmon, 1935). An intermediate stage in deterioration is indicated by a great increase in the abundance of bluegrass (Poa pratensis), blue grama grass (Bouteloua gracilis), or buffalo grass (Buchloe dactyloides), the latter especially on …

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

Nebraska Agricultural Experiment Station: Historical Research Bulletins

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 …

Anatomy And Histology Of The Digestive Tract Of A Deep-Sea Fish Coelorhynchus Carminatus, Elly M. Jacobsen

University Studies (University of Nebraska) (1888–1984)

This paper deals with the anatomy and histology of the digestive tube of one of the grenadiers or rat-tails, Coelorhynchus carminatus (Goode), as classified by Jordan & Evermann (1896).1 Many studies on the structure of the digestive tracts of fishes have been made in the past, and pioneer work in the teleost group was done by Valatour in 1861, Pillet in 1894 on the Pleuronectidae, and Gulland in 1898 on the salmon. More recent studies have been made by Greene (1912) on the king salmon, Blake 2 (1930) on the sea bass, and Rogick (1931) on the minnow.

Ecological Study Of The Weed Population Of Eastern Nebraska, Elva L. Norris

University Studies (University of Nebraska) (1888–1984)

EXACT knowledge of the relations existing between weeds and cultivated crops is very limited. This is true also of the amount of viable weed seed present in arable soil. Impressions and observations have been recorded, but very few quantitative investigations have been made. The numerous circulars and bulletins about weeds, issued by many experiment stations, deal mostly with descriptions of species and methods of weed control. The present research was undertaken primarily to determine the relationship which exists between weeds and cultivated crops, but also to obtain an estimation of the number of viable weed seeds present in the soil. …

The White River Oligocene Rodent Diplolophus, Erwin Hinckley Barbour, Thompson M. Stout

Bulletin of the University of Nebraska State Museum (1924–2023)

The rich and varied nature of the mammalian faunas of the White River Oligocene has been recognized for many years, but the exact geologic succession is only now becoming known. In these faunal assemblages the rodents and lagomorphs appear to have been important elements, perhaps numerically as abundant in the Oligocene as are these same groups at present.

Increase Of Sporobolus Cryptandrus In Pastures Of Eastern Nebraska, J. E. Weaver, Walter W. Hansen

Papers of John E. Weaver (1884–1956)

The severe drought of 1934 to 1938 has resulted in great losses in the plant
populations of native pastures. In Nebraska, little bluestem, Andropogon scoparius, and Kentucky bluegrass, Poa pratensis, have almost disappeared, while big bluestem, Andropogon furcatus, and numerous other important pasture grasses have suffered heavy losses. In addition to shiftings within the plant populations to compensate these losses, such as an enormous increase in side-oats grama, Bouteloua curtipendula, notable and widely spread local extensions have occurred. Over thousands of pastures western wheat grass, Agropyron smithii, has spread widely, and in similar numbers sand …

Birdbanding, Frederick C. Lincoln

United States Fish and Wildlife Service: Publications

Birdbanding, by means of numbered bands, provides a method of studying living birds of all kinds. Scientific banding dates back to 1899, when a Danish schoolmaster, H. Chr. C. Mortensen, commenced systematically to band storks, teals, starlings, and two or three species of birds of prey. His success at once attracted the attention of European ornithologists, and it was not long before the birdbanding work came into prominence. At the present time banding is being actively conducted in North America as well as in England, Finland, Norway, Sweden, Denmark, Russia, Iceland, Germany, Holland, Belgium, France, Switzerland, Hungary, Bulgaria, India, Morocco, …

Common Native Grasses Of Nebraska, A. L. Frolik, F. D. Keim

Nebraska Agricultural Experiment Station: Historical Circulars

Twenty-four native grasses that are the most important and most generally distributed in Nebraska are described and illustrated in this circular. Information concerning their distribution and economic value is given. Anyone interested in learning to identify the common native grasses should be able to do so by comparing plant specimens with the illustrations and descriptions herein presented. The work of identifying grasses may seem technical and limited only to botanists or those with similar training. Nearly anyone, however, can learn to identify many of the native grasses if willing to spend a little time and effort.

Land Transfers In Twelve Counties In Nebraska, 1928-1933, L. F. Garey

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The land transfers in twelve counties in Nebraska for the period 1928 to 1933 have been studied and the findings are submitted in this bulletin. The data on which the study is based were obtained from records in the office of the Register of Deeds in each county and from other sources and include transfers which occurred during the period indicated. The counties included in the study are Boone, Cass, Cuming, Dakota, Dawes, Frontier, Gage, Hamilton, Harlan, Lancaster, Nuckolls, and Valley.

A Manual For Hog Raisers, W. J. Loeffel

Nebraska Agricultural Experiment Station: Historical Circulars

Hogs are one of Nebraska's principal sources of agricultural income. The popularity of the pig is doubtless due largely to his efficiency as a meat producer. He uses less feed to make a given gain than either the steer or the sheep. On being slaughtered, the pig dresses out a higher percentage of meat than either of the other two meat animals. Since pork is generally fatter than beef or lamb, it has a higher energy value. Pork lends itself to curing processes and, as cured meat and lard, occupies an important place in the world's commerce. Processing aids in …

The Tax System Of Nebraska With Special Reference To Its Relation To Agriculture, L. B. Snyder

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Progress in governmental affairs calls for constant study of matters pertaining to government. The recent agitation for moratoria on debts and taxes and the many tax reforms suggested are evidence of the need for such study. Before satisfactory reforms can be made, information on receipts and expenditures by governmental agencies must be secured. The expense connected with collecting, tabulating, and analyzing such data has prevented private agencies of the state from doing this. Because it was felt that such information would be useful and could be obtained by the College of Agriculture, this study was undertaken.

Influence Of Age Of Dairy Cattle And Season Of The Year On The Sex Ratio Of Calves And Services Required For Conception, R. F. Morgan, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The present study was based on records of the dairy herd of the University of Nebraska for the period 1896 to 1934, and covers five breeds, Holsteins, Jerseys, Guernseys, Ayrshires, and milking Shorthorns. In all, 2,090 cows have been included. The purpose was to determine the influence of the age of the bull, the age of the cow, and the season of the year upon the number of services required for conception, and to determine also the influence of these factors upon the sex ratio of calves born, number of twins born, and the percentage of abortion.

Feeding And Care Of Calves, R. R. Thalman

Nebraska Agricultural Experiment Station: Historical Circulars

It is not infrequent that considerable difficulty is encountered in raising calves with limited amounts of milk or none at all. Requests for information on calf gruels, mixed grain feeds, and commercial supplements are frequent enough to make a short circular upon this subject seem desirable. Furthermore, as the more diversified agricultural program gets under way these requests are increasmg.

Wound Healing In Potatoes (Triumph Variety) As Influenced By Type Of Injury, Nature Of Initial Exposure, And Storage Conditions, H. O. Werner

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Tubers of the Triumph variety of potatoes, the one most extensively grown in western Nebraska, are more susceptible than those of other varieties to the various types of injury that occur at harvest time. This greater susceptibility is chiefly the result of long stolons, unusual tenderness of skin, and ease with which the tubers crack. The two latter characteristics have been accentuated by the custom of late planting adopted generally throughout the region in recent years. Many of the difficulties could be avoided by growing another variety. However, as there now seems to be no other variety as well adapted …

Studies On The Vitamin A Content Of Cheese, I. L. Hathaway, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The vitamin-A contents of twenty-two kinds of cheeses were studied by feeding these cheeses to rats whose body stores of vitamin A had been exhausted by being fed a vitamin-A-deficient diet. Twelve experiments were made in which approximately 1100 rats were used. There was considerable variation in the vitamin-A content of the samples studied. The samples of cottage, Neufchatel, and Limburger cheeses had the lowest vitamin-A potency.
