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

A resume of the First Half-Century of Research 1888 - 1938 at the Utah Agricultural Experiment Station including the Biennial Report 1936 - 1938.
The Utah Agricultural Experiment Station in reaching the fiftieth year of its history can look back upon a brilliant record of achievement covering the practical as well as the more fundamental problems of agriculture in this arid state. The difficulties encountered in conquering deserts down through human history have demonstrated the mastery of man's spirit over his physical environment. Man's destiny to multiply, subdue, and replenish the earth cannot be accomplished by enjoying the fruits of …
A Manual For Hog Raisers, W. J. Loeffel
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 …

Bulletin No. 280 - Sinusitis Of Turkeys And Its Treatment, D. E. Madsen
UAES Bulletins
Sinusitis has long been recognized as one of the barriers to profitable production of chicken products; and with the growth of commercial turkey production in the west its existence in this bird has become increasingly significant. In Utah areas considerable loss is encountered yearly from this disease in turkeys. This loss has prompted some investigations as to what measures may be adopted for its control.

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

The Vitamin A Content Of Soybean Silage And Of A.I.V., Molasses, And Common Corn Silages, And The Effect Of Feeding These Materials Upon The Vitamin A Content Of Milk, I. L. Hathaway, H. P. Davis, J. C. Brauer
Nebraska Agricultural Experiment Station: Historical Research Bulletins
A study was made of the vitamin A content of soybean silage, and of A.l.V., molasses, and common corn silage. The silages were fed to groups of cows and the vitamin A content of their milk determined. The vitamin A determinations were made by feeding the silage or the milk to groups of rats whose body stores of this vitamin had been depleted by being fed a vitamin-A-deficient ration. Approximately 780 rats were used in these experiments. There were no apparent ill effects of feeding as much as 3.2 grams of the A.l.V. silage per rat per day for eight …

Nebraska Agricultural Experiment Station: Historical Research Bulletins
1. Two lots of newly hatched chicks were fed rations differing only in five per cent of their make-up. In the ration of one lot five parts of linseed oil meal were added to 95 parts of the base, and in the other ration a mixture of 4.5 parts of cottonseed meal and 0.5 part of starch was added, to keep the protein level the same. The remaining portions of the two concentrates were made up of five parts each of meat scraps and fish meal. 2. The amounts of feed consumed by all chicks of both lots were kept …
The Lungs And Respiration In The Frog, Peter P. Strassburg
The Lungs And Respiration In The Frog, Peter P. Strassburg
Bachelors’ Theses
In a wide sense, respiration is sometimes defined as the gaseous exchange constantly taking place between an organism and its environment. Essentially it is concerned with the intake of oxygen and the output of carbon dioxide but it also includes any other gas exchange that might occur. Small organisms take oxygen directly from the air or from the watery medium surrounding them into all parts of their structures. They also give off carbon dioxide from all their parts directly into the surrounding medium. They can do this successfully because they are small enough to have every cell in direct or …

Bachelors’ Theses
The circulatory system of the vertebrates is one of the most important found in the animal kingdom. The reason being that it carries food, oxygen, and hormones to all parts of the body and also removes all types of waste materials. this system involves a pump-like apparatus, called the heart, to which are attached tube-like vessels called arteries and veins. A liquid called a fluid-tissue circulates in this closed transportation system which is said to be closed in order to distinguish it from a semi-closed or open system in which a sinus or tissue cavity separates certain arteries and veins. …

Root Development Of Young Delicious Apple Trees As Affected By Soils And By Cultural Treatments, W. W. Yocum
University of Nebraska-Lincoln Extension: Historical Materials
Young Delicious apple trees were grown in two soil types, clay loam and loess, in eastern Nebraska, under a variety of cultural conditions. The development of roots and tops was studied for the first three years after transplanting in the orchards. In all, 73 trees were excavated.
The first two years were about normal in precipitation at Lincoln (locale of the clay loam) while at Union (locale of the loess) there was a deficit of over 9 inches each year. The third year, 1934, was one of severe drought and heat at both stations. The total rainfall deficiency for the …

1. The effect of adding to a basal ration a protein concentrate consisting of meat scraps alone was compared with one made up of a mixture of meat scraps, fish meal, and dried buttermilk by means of growth and body-analysis experiments. 2. The percentages of nitrogen, calcium, and phosphorus contained in the chicks of the lot fed the mixture of three proteins were slightly higher than those found in the lot fed meat scraps as the concentrate. 3. The percentage rate of gain and the gain per gram of nitrogen fed were greater in the lot fed the mixture of …
Comparative Physiology Of Actinomyces In Relation To Potato Scab, Mitrofan M. Afanasiev
Comparative Physiology Of Actinomyces In Relation To Potato Scab, Mitrofan M. Afanasiev
Nebraska Agricultural Experiment Station: Historical Research Bulletins
The present work was undertaken with the purpose of investigating the physiology of different strains of A. scabies as compared with saprophytic Actinomyces. By a comparative study of these groups, it was thought that differences in the physiology of the two might be found which would give a better understanding of the nature of this parasitism and also of the metabolism of Actinomyces in general. In addition, it was hoped that the determination of the factors influencing the parasitism of Actinomyces might establish a basis for the development of more efficient methods of controlling scab diseases. The present investigation …

Bulletin No. 281 - Sorghums Varietal Tests In Utah, R. W. Woodward, D. C. Tingey, R. J. Evans
UAES Bulletins
Sorghums are not grown to any appreciable extent in Utah except in the Virgin River valley in the southwestern portion of the State. No experimental work on sorghum culture had been done prior to 1931 except on the dry land of Juab County near Nephi. Those early tests, discontinued after 1917, indicated that sorghums were poorly adapted to such conditions.
Numerous improved varieties have been produced since that time, some of which are adapted to relatively short growing seasons.
This bulletin will discuss the practicability of growing some of these varieties of sorghum in Utah and their economic value compared …

Relation Of Height At Withers And Chest Girth To Live Weight Of Dairy Cattle Of Different Breeds And Ages, H. P. Davis, R. F. Morgan, Samuel Brody, A. C. Ragsdale
Nebraska Agricultural Experiment Station: Historical Research Bulletins
The size of a dairy cow is important from the standpoint of feed consumption and economy of production and also as an indication of the expected size of offspring. The ultimate disposal of dairy cattle is for beef, and the measure of returns is based upon size and condition. A method for the determination of the approximate weights of dairy females, where scales are not available, is needed. Measurements of dairy cattle which show development and skeletal growth by ages in relationship to weight are presented here for four different dairy breeds.

Bulletin No. 277 - A Study Of Utah's Winter Range: Composition Of Forage Plants And Use Of Supplements, A. C. Esplin, J. E. Greaves, L. A. Stoddart
UAES Bulletins
Range forage provides the foundation for the maintenance ration available for most sheep wintered in Utah. The nature and amount of supplemental concentrate or roughage needed with this forage to provide an adequate and efficient ration for sheep naturally depends on the nature and amount of range forage available. Present uncertainty as to the relative merits of the various available supplements originates largely through a lack of definite knowledge as to the composition and feeding value of the various range plants that go to make up the range-forage supply on the particular range in question.
