The Vitamin A Content Of The Milk Of Holstein, Ayrshire, Jersey, And Guernsey Cows, H. P. Davis, I. L. Hathaway

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A comparative study of the vitamin A content of milk produced by Holstein, Ayrshire, Jersey, and Guernsey cows was made by comparing the growth produced by 560 rats receiving milk from these breeds as their only source of vitamin A. The results showed some slight irregular differences in the gains produced by the milk from the different breeds. When these differences were considered in view of the individual variation of the experimental animals, they appeared negligible. This conclusion was substantiated by a statistical examination of the data. From the results of this study in which the experiments were duplicated, it …

Circular No. 92 - Torrential Floods In Northern Utah

UAES Circulars

On account of the recurring nature and the destructive character of the floods which have devastated property in Davis County and elsewhere in recent years, it appeared advisable to make a special study of the situation, I, therefore, in 1930, appointed a commission of citizens whom I deemed especially qualified, including practical engineers, geologists, foresters, and stockmen, asking them "to study the origin and cause of floods in Davis County and other parts of the state, and to ascertain whether any flood prevention measures are feasible".

Circular No. 91 - Establishing Snow Courses And Making Snow Surveys, George D. Clyde

UAES Circulars

The major portion of the annual precipitation in the semi-arid west falls as snow. It piles up in the mountains and forms the main source of the water in the creeks and rivers draining the mountainous areas. Some of these streams flow the year around while others and intermittent, flowing only as long as the snow in the mountains lasts. The water-supply for irrigation, power development, and municipal purposes is derived largely from winter snows. A knowledge of the extent of the snow cover and its water content is, therefore, necessary for the proper utilization of this great natural resource. …

Bulletin No. 223 - Feeding Value Of Alfalfa Hay Treated With Calcium Arsenate, H. J. Frederick

UAES Bulletins

For a number of years many tons of sprayed or dusted hay have been fed successfully to livestock by stockmen interested in controlling the alfalfa weevil; nevertheless. the supposed cases of poisoning that have been reported naturally have caused concern among feeders.

Further confusion on this question has resulted from reports on studies designed to determine the effect of lead arsenate instead of calcium arsenate.

Whether the lead in lead arsenate has been a more injurious agent than the arsenic, of course, is difficult to state. Most of the experiments performed in the feeding of sprayed or dusted hay have …

The Use Of A Small Electric Motor In Silo Filling, E. E. Brackett, E. B. Lewis

Nebraska Agricultural Experiment Station: Historical Circulars

Filling a silo 30 feet or more in height with a motor as small as five horsepower has been looked upon in general by Nebraska farmers as an impractical, if not impossible, procedure. The practice is not unheard of in other states, and certainly the possibility of avoiding the large tractor-driven cutters and the large crews will be welcomed by those who have available service from power lines.

A Study Of Preprations From Buckwheat Hulls, Rudolf A. Zivnuska

Bachelors’ Theses

Industry is trying to make use of all possible material. In an age of great manufacturing plants, efficiency Is decreased and costs mount rapidly whenever a waste product tends to be formed in a process. The problem resolves itself into selling someone else the waste products in a modified form, if necessary. At the present time, waste products support industries to which they were formerly a liability. In the Ford wood waste distillation plant in 1929, over $2,100,000 worth of benzol was sold. This is in addition to gas, charcoal, methanol and power gotten from the exothermic action from the …

Principles Of Irrigation Farming As Developed By American Field Experiments, Prabh Dyall Sikka

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Irrigation is "the artificial application of water to the soil for the purpose of getting large and steady crop yields". It is supplementary to rainfall and the quantity of water applied and the time of application, therefore, must be determined by the character of the rainfall. Irrigation is usually practiced in those regions which have low rainfall as natural precipitation at such places is insufficient to meet the full water requirements of crops.

Rb30-245 Water Supply And Sewage Disposal Systems For Farm Homes, Ivan D. Wood, E.B. Lewis

University of Nebraska-Lincoln Extension: Historical Materials

When the well "goes dry" or when the windmill or pump breaks down, every one in the household immediately appreciates the value fo plenty of water. In other words, "You never miss the water until the well runs dry." Fortunately, in most sections of this state, plenty of pure water may be obtained by sinking wells of moderate depth, yet surprisingly few farm homes are supplied with running water in the kitchen even though the barn yards are equipped with hydrants and tanks.

It is the purpose of this bulletin to present a number of water supply and sewage disposal …

Homes For Birds, E. R. Kalmbach, W. L. Mcatee

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Birds appeal strongly to the interest and affection of mankind. Not only do they charm by their graceful forms, harmonious colors, sprightly actions, and usually pleasing notes, but they have an even more important claim upon our esteem because of their great economic value.

Birds feed upon practically all insect pests. They are voracious, able to move freely from place to place, and exert a steady influence in keeping down the swelling tide of insect life.

For economic as well as for esthetic reasons, therefore, an effort should be made to attract and protect birds and to increase their numbers. …

Circular No. 82 - Lamb Slaughtering And Cutting, Harry H. Smith

UAES Circulars

The old saying that "the shoemaker's wife goes without shoes" might be changed to read "the lamb raiser and feeder of the west does not eat lamb." About three-fourths of the population of the United states is east of the Mississippi River, and about 90 per cent of all the lamb and mutton produced in the United states is consumed east of the Mississippi. It has been observed, both on the farms and in towns, that a large percentage of people in the sheep sections of the west have tasted neither lamb nor mutton.

Circular No. 80 - Domestic Slaughtering, Cutting, And Curing Of Pork, Harry H. Smith

UAES Circulars

The practice of slaughtering hogs on the farm is being followed rather extensively by the farmers of this state. It is an economic practice and should be more generally followed because by this practice a supply of meat is available throughout the year. In all ages meat has been the principal article of diet of the ruling races. It is a natural and necessary part of man's diet. The races of people who have not included meat in their diet are today numbered among the weaker and more backward nations.

Bulletin No. 212 - Studies On The Morphology Of The Beet Leafhopper, G. F. Knowlton

UAES Bulletins

The beet leafhopper, Eutettix tenellus (Baker), is one of the most serious insect pests of western North America. Its chief importance is as a vector of the plant disease curly-top, which it transmits to beets, tomatoes, beans, melons, and many other agricultural plants. The virus apparently is introduced into the plant during the process of feeding, and is responsible for the frequent and often enormous losses to the sugar-beet growers and sugar manufacturers of the west. Apparently, the virus multiplies and remains active in the body of a leafhopper for some time, making it possible for the insect, after once …

Bulletin No. 213 - Food Habits Of Utah Farm Families, Almeda Perry Brown

UAES Bulletins

This report is merely an attempt to set forth the findings of the investigation without making claim to their being conclusive except for the families included in the study. While the study was carried into a relatively large portion of the state, the records are too few in number for any claim to be made that they represent community food conditions. It is believed, however, that the records which form the basis of this report are representative of the food situation in the homes from which they come.

Circular No. 77 - Measurement Of Irrigation Water, George D. Clyde

UAES Circulars

Water is the limiting factor in Utah's agricultural development. In spite of its admitted value the farmer knows less about the measurement of water than about any of the other commodities which he handles. He knows how to measure his land, his crops and his cattle, but he has little conception of how to measure his most valuable asset, viz., irrigation water. The importance of water measurement is not appreciated until the water-supply becomes over-appropriated and users begin interfering with each other's rights. Expensive litigation, which always follow controversies over water, is gradually convincing the farmer that water should be …

Bulletin No. 210 - The Mineral Content Of Grains, J. E. Greaves, C. T. Hirst

UAES Bulletins

It is generally recognized that shrunken, frosted, or smutty grain is inferior to sound, clean, plump grain. Much has been done on the protein content of grain, and the best millers today purchase grain for its protein content. Few give any consideration to its minerals. Yet do two bushels of sound, plump, clean grain of known protein content grown under the same or different conditions, have the same mineral content? If not, it is of importance to both the producer and consumer: to the consumer because it governs the nutritive value of the product; to the producer because it represents …

Bulletin No. 207 - The Physical Cure Character Of Milk And Its Relationship To The Digestability And Food Value Of Milk For Infants, R. L. Hill

UAES Bulletins

In the feeding of infants,' cows' milk is the best and most common substitute for human milk. In the feeding of delicate infants, however, considerable difficulty is often experienced from its use. The ideal substitute for mothers' milk has not been found, and most of the clinical effort has been directed towards the modification of cows' milk for infants.

Comparatively little research has been done on the difference in the digestibility and food value of milks from different cows for the infant. It is a well-known fact that the curd of cows' milk forms in a tough mass which varies …

Bulletin No. 206 - Treehopper Injury In Utah Orchards, Charles J. Sorenson

UAES Bulletins

Treehopper injury is a problem that has given many fruit growers in Utah some concern during recent years. These people have observed that their young fruit trees and the twigs and smaller branches of older trees have been attacked during the autumn of each year in a manner that produced numerous cuts which later formed scars. The trees frequently became unthrifty, and more or less deformed and stunted, as a result of these annual attacks.

The investigation reported in this publication was made for the purpose of ascertaining the present status of the treehopper situation in Utah orchards.

Bulletin No. 205 - The Beet Leafhopper In Utah: A Study Of Its Distribution And The Occurrence Of Curly-Top, George F. Knowlton

UAES Bulletins

The sugar-beet industry of Utah, and many other western states, has suffered enormous losses from curly-top. Under natural conditions this disease is transmitted, so far as known, solely through the feeding of the beet leafhopper, Eutettix tenellus (Baker), the so-called "white fly." The serious damage of 1924 and 1926 has especially emphasized the necessity for more knowledge concerning the problem.

Spraying Tree Fruits, C. C. Wiggans, E. H. Hoppert

Nebraska Agricultural Experiment Station: Historical Circulars

The production of sound, clean fruit is unquestionably one of the major problems facing the modern fruit grower. Culture may be neglected and pruning delayed for a time but the omission of sprays for even a single season demonstrates their absolute necessity. This applies equally to the commercial grower and to the farmer or gardener who has only a few trees.

Bulletin No. 203 - Cattle Ranching In Utah: Report Of A Preliminary Economic Survey Of The Ranch Situations As Of 1925, William Peterson, P. V. Cardon, K. C. Ikeler, Geroge Stewart, A. C. Esplin

UAES Bulletins

The Mexican War ended in 1846, but the treaty of Guadalupe Hidalgo was not signed until 1848. Meantime, Utah was occupied by the Mormon pioneers, who having no land laws to guide them took land according to a plan furnished by Brigham Young. In Salt Lake City 10-acre blocks were divided into 8 building lots of 1 1/4 acres each. Just at the edge of the city were "five acre lots to accommodate mechanics and artisans; next beyond were 10-acre lots, followed by forty and eighty acres, where farmers could build and reside."

Bulletin No. 199 - Mutual Irrigation Companies In Utah, Wells A. Hutchins

UAES Bulletins

Cooperation has been an important factor in the development of agriculture under irrigation in Utah. The Mormon pioneers in the Great Basin were the first Anglo-Saxons to practice irrigation on an extensive scale in the United States; hence, it is significant that from the first their irrigation work was accomplished largely as a result of community effort. Private diversions of water there were, of course, even in the earliest times, but for years they were quite out of place in an environment that took quick toll of those individualists who scorned the protection of numbers and refused to cooperate. The …
