Circular No. 69 - Clean Milk And Its Production, E. G. Carter Feb 1928

Circular No. 69 - Clean Milk And Its Production, E. G. Carter

UAES Circulars

Successful dairy farming is fast growing into an exacting profession, and in order to be successful the dairy farmer must not only recognize the value of good clean milk but must know how to produce it as well. Good milk, good butter, and good cheese are acknowledged to be in great demand, and each brings fair financial returns.

Since the beginning of the dairy industry one of the big difficulties has been that of obtaining clean milk and cream. By applying the best scientific methods in the manufacture of dairy products the ill effect of impure milk can be partly …


Circular No. 70 - The Agricultural Outlook For Utah, P. V. Cardon, W. P. Thomas Feb 1928

Circular No. 70 - The Agricultural Outlook For Utah, P. V. Cardon, W. P. Thomas

UAES Circulars

In preparing the following statement of Utah's relation to the national agricultural outlook for 1928, the writers have been guided by three fundamental considerations : (a) Utah is a livestock state; (b) feed production is the basis of Utah agriculture; and (c) definite physical, geographic, and economic limitations govern Utah's production of crops other than feed crops.

Trends And Silvicultural Significance Of Upland Forest Successions In Southern New England, Harold J. Lutz Jan 1928

Trends And Silvicultural Significance Of Upland Forest Successions In Southern New England, Harold J. Lutz

Yale School of the Environment Bulletin Series

The problems encountered in the silvicultural treatment of southern New England forests are many. They result largely from the extremely diverse and complex conditions under which the forest is developed. Due to the glaciated nature of the region the soil character changes radically within relatively short distances. With changes in soil from place to place come minor changes of forest composition. One of the chief reasons for the problems which the silviculturalist encounters in this region is the large number of species which make up the stands. There are approximately thirty commercially important forest trees in southern New England. The …

Ec28-234 Nebraska System For Tattooing Hogs For Identification After Slaughter, G.R. Boomer, O.O. Waggener Jan 1928

Ec28-234 Nebraska System For Tattooing Hogs For Identification After Slaughter, G.R. Boomer, O.O. Waggener

University of Nebraska-Lincoln Extension: Historical Materials

A plan to identify the individual farm upon which hogs reaching markets are produced has been developed in connection with the efforts toward eradicating tuberculosis among farm animals. While primarily intended as a means of tracing back to determine sources of disease infection, the system of tattooing which is being developed has other significant possibilities. With the growing emphasis on quality products in the market, it is only fair that the producers of high quality commodities receive the premiums paid by processors and consumers. Health of farm animals is a quality factor. The producer of healthy hogs should be rewarded. …


Ec28-36 Spraying Tree Fruits (Revised March 1932), C.C. Wiggans, E.H. Hoppert Jan 1928

Ec28-36 Spraying Tree Fruits (Revised March 1932), C.C. Wiggans, E.H. Hoppert

University of Nebraska-Lincoln Extension: Historical Materials

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.

Spray materials, equipment, management, schedules, insect pests and orchard diseases are discussed in this 1928 extension circular.


Rb28-229 Fattening Steers Of Various Ages, H.J. Gramlich Jan 1928

Rb28-229 Fattening Steers Of Various Ages, H.J. Gramlich

University of Nebraska-Lincoln Extension: Historical Materials

During recent years the beef industry has undergone vast changes. These have been made necessary in part by economic conditions and in part by changes in the demands of the American people. The tendency has been toward earlier marketing of steers, so that instead of going to the block as mature individuals at from 3 to 5 years of age, they are now reaching the market at a much younger age. In consuming centers where only heavy carcasses of beef were demanded formerly there is a call today for carcasses of the yearling and long yearling class.

The experiments reported …


A Research Delusion, George L. Peltier Jan 1928

A Research Delusion, George L. Peltier

Department of Plant Pathology: Faculty Publications

With the administrative heads of many of our educational institutions demanding a doctorate of every member of the permanent staff, as it is supposed to be a prerogative for research, and the issuing of a list of titles published each year by their staff, the urge for so-called research, namely, a list of titles, goes madly on. In fact publication sometimes becomes a sort of self-defense, for the absence of any titles over a brief period of years stamps one either as lacking the ability of doing research or inefficient. Likewise, such a policy has permeated the staff, so that …


Wild Birds Introduced Or Transplanted In North America, John C. Phillips Jan 1928

Wild Birds Introduced Or Transplanted In North America, John C. Phillips

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

The early history of the introduction of foreign birds into this country is mostly clothed in darkness. The records of many attempts, if such there were, have long since been buried in back numbers of local newspapers, and if any experiment was unsuccessful it was soon forgotten. Hence, one trying to get an accurate idea of what has happened soon realizes that he is following a hopeless quest. It is much the same with the transplanting of native birds, especially game birds, which have been carried about all over the country from west to east and from east to west …


The Structure And Development Of Corallobothrium With Descriptions Of Two New Fish Tapeworms (With Five Plates), Hiram Eli Essex Jan 1928

The Structure And Development Of Corallobothrium With Descriptions Of Two New Fish Tapeworms (With Five Plates), Hiram Eli Essex

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Introduction

Representatives of the genus Corallobothrium from American fish have never been described. Marshall and Gilbert (1905) report two members of this genus taken from Ameiurus melas (black bullhead) caught in the lakes at Madison, Wisconsin. La Rue (1914) refers to an undescribed species of Corallobothrium encysted in the livers of A. melas and A. nebulosus (common bullhead) from the Illinois River. Ward (1918) noted the presence of a species of Corallobothrium in lctalurus punctatus (channel-cat) at Milford, Nebraska. Aside from these incidental references, the American literature contains no information on this interesting group of fish tapeworms.

Biological And Psychological Study Of Twenty Pairs Of Twins Ranging From Seven To Eighteen Years Of Age, Albert C. Worden Jan 1928

Biological And Psychological Study Of Twenty Pairs Of Twins Ranging From Seven To Eighteen Years Of Age, Albert C. Worden

University of the Pacific Theses and Dissertations

Although twins have always been of great Interest the only early data available are upon conjoined twins. The first record of such twins, which 18 known, 1s of the Bid-dendent Maids in the year 1100 A. D. From that date to the year 1824 when the Siamese Twins were born and later made famous by Barnum and Bailey's Circus, there have been many Interesting accounts of conjoined twins, but the nature of the present work and the probable unreliability of these accounts would make any discussion on the subject of these early conjoined twins not worth while.

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."

Structure Of Texas Vegetation, J. E. Weaver Oct 1927

Structure Of Texas Vegetation, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

In his studies on the structure of the vegetation of eastern Texas, Tharp has recently made a notable contribution to plant ecology. That unexplored vegetation has always had an irresistible attraction for botanists is well ex-emplified in the resume of studies of Texas vegetation. An adequate review of the earlier work is given. This work began even before the colonists declared their independence from Mexico. It includes the studies of Lindheimer, who was both a geographer and collector; deals with the numerous papers along broad ecological lines by Bray; and traces the studies to the recent analysis of the vegetation …


A Critical Study Of Blood Sugar Determination, Myrtle L. Sand Aug 1927

A Critical Study Of Blood Sugar Determination, Myrtle L. Sand

Bachelors’ Theses

There are many methods, for the determination of this sugar, in use now, some used widely others not so widely. Methods vary as to accuracy and there has been many comparisons made between various methods. There is a recognized clinical need of a method for a quantitative sugar determination which will be quick, accurate, and adapted for use with small blood samples. As a result of this last, namely adaptation for use with small blood samples, several micro chemical methods have been published. One of these is the Epstein method. It is simple and supposed to make the estimation of …

Stem Rust In Nebraska. Part I. General Survey Of Sources. Part Ii. Identification Of The Physiologic Forms Of Puccinia Graminis From Various Sources, George L. Peltier, A. F. Thiel Jul 1927

Stem Rust In Nebraska. Part I. General Survey Of Sources. Part Ii. Identification Of The Physiologic Forms Of Puccinia Graminis From Various Sources, George L. Peltier, A. F. Thiel

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Part I: Since the inception of the barberry eradication campaign in 1918 in Nebraska, the question has continually been asked, "Will the eradication of the barberry in the state eliminate or materially reduce stem rust?" In order that an answer might be obtained, an investigation to determine the sources of primary infection of stem rust on cereals was inaugurated in the spring of 1921. Although these studies have been carried on for 6 years, no definite statement regarding the relative importance of the primary sources and the amount of stem rust prevalent in the state from season to season originating …

Circular No. 66 - Physical Curd Character Of Milk And Its Probably Relation To Infant Nutrition, R. L. Hill Jun 1927

Circular No. 66 - Physical Curd Character Of Milk And Its Probably Relation To Infant Nutrition, R. L. Hill

UAES Circulars

A problem which must be met by many mothers is that of obtaining for their infants an adequate substitute for breast milk. The weaning period is a very critical time in the life of every infant. Its ability to properly digest and assimilate the food supplied will largely determine its state of health, provided it is kept free from infection.

Milk formulas for the feeding of infants are often made up to conform to certain fat requirements. Some infants apparently have difficulty in properly assimilating a milk with a high fat content. This may be due to a low fat …

UAES Circulars

This contest is conducted on a part of the Utah Agricultural College Farm near the experimental poultry yards. It is managed by the Poultry Department with an experienced poultry raiser in direct charge of the feeding and care of the hens in the contest. The buildings, grounds, and fences were built and furnished by the Experiment Station.


Bulletin No. 202 - Some Observations On Winter Injury In Utah Peach Orchards, T. H. Abell Jun 1927

Bulletin No. 202 - Some Observations On Winter Injury In Utah Peach Orchards, T. H. Abell

UAES Bulletins

During the winter following the freeze, fruit growers in Utah were deeply concerned over the effects of the cold on their orchards, since it was observed that not only were fruit buds killed, but the tissues of the trunks, limbs, and twigs were turning brown. The question at once arose as to whether or not this browning indicated the approaching death of the trees. It was, therefore, considered important to determine, if possible, the nature and extent of the damage, to discover any factor which might have favored or lessened the injury, and finally to offer suggestions to the orchardist …

The Development Of The Gametophyte And Apogamous Sporophyte In Cheilanthes Feei, Moore, Florence Madeline Steil Jun 1927

The Development Of The Gametophyte And Apogamous Sporophyte In Cheilanthes Feei, Moore, Florence Madeline Steil

Bachelors’ Theses

Since Leszeye-Suminski's (1848) discovery of tracheids near the apical notch of the prothallium of Pteris sulcata, problems pertaining to apogamy or related phenomena have offered a wide field for botanists. Nearly all workers interested in the study of apogamous ferns, have contributed something of physiological or cytological interest
