Population Change In South Dakota Small Towns And Cities, D. R. Field, R. M. Dimit Mar 1970

Population Change In South Dakota Small Towns And Cities, D. R. Field, R. M. Dimit

Research Bulletins of the South Dakota Agricultural Experiment Station (1887-2011)

The purpose of this study was to identify factors associated with growth and decline of incorporated places (i.e. small towns and cities) in South Dakota. This purpose or objective is part of a broader focus concerning the growth and decline of incorporated places in South Dakota. The Department of Rural Sociology currently has three objectives in its communities research program: 1) to identify factors associated with population change in communities, 2) to determine the results of such change, and 3) to identify the kinds of adjustments needed to build communities which can grow and prosper in a constantly changing society.

Effect Of Flushing And Gonadotropin On Ovulation Rate Of Yearling Ewes On Range, James K. Lewis, Leon F. Bush, Marshall Haferkamp, W. R. Trevillyan Jan 1970

Effect Of Flushing And Gonadotropin On Ovulation Rate Of Yearling Ewes On Range, James K. Lewis, Leon F. Bush, Marshall Haferkamp, W. R. Trevillyan

South Dakota Sheep Field Day Research Reports, 1970

Improvement of the reproduction rate of range ewes is of the utmost importance to the range sheep producer. Good grazing management and proper supplementation have been shown to be important. Flushing range ewes has given conflicting results. Gonadotrophic hormones have been used to increase ovulation rates but have been less successful with yearlings than with older ewes.


Performance Of Lambs Fed Rations With Oyster Shells Or Various Levels Of Hay, W. M. Larson, L. B. Embry, R. M. Luther Jan 1970

Performance Of Lambs Fed Rations With Oyster Shells Or Various Levels Of Hay, W. M. Larson, L. B. Embry, R. M. Luther

South Dakota Sheep Field Day Research Reports, 1970

High-concentrate rations have been shown to have several advantages in large cattle feeding operations because they produce high rates of gain with low feed requirements. It has been a common practice to feed lamb rations with relatively high levels of roughage. However, lamb feeders might also benefit under many conditions if results similar to those with cattle fed high-concentrate rations could be obtained with lambs. Little research has been reported on the relative value for lambs of all-concentrate rations and those with low levels of roughage or roughage replacers such as oyster shells. Two experiments were conducted to study feedlot …


Phosphatic Urinary Calculi, Royce J. Emerick, Lawrence B. Embry Jan 1970

Phosphatic Urinary Calculi, Royce J. Emerick, Lawrence B. Embry

South Dakota Sheep Field Day Research Reports, 1970

Many questions as to the cause, prevention and treatment of urinary calculi remain yet unanswered. However, many experiments the past several years provide a basis for a greater understanding of this problem and its control.


The Effect Of Ral Implants On Lamb Performance, Leon F. Bush, Frank Whetzal Jan 1970

The Effect Of Ral Implants On Lamb Performance, Leon F. Bush, Frank Whetzal

South Dakota Sheep Field Day Research Reports, 1970

One way to improve rate and efficiency of lamb production is by the use of growth stimulating compounds. Resorcylic Acid Lactone (RAL) is a relatively new growth stimulating compound that has been shown to improve weight gains and feed efficiency of growing and finishing beef cattle. South Dakota researchers have reported 13% faster gains on 9.7% less feed for yearling steers implanted with 36 mg. RAL when compared to control steers. Two trials were conducted to determine if a 12 mg. implant of RAL would be effective in improving performance of young growing lambs.


The Influence Of Feedlot Weight On Market Lamb Peformance And Body Composition, Wallace Koester, Leon F. Bush Jan 1970

The Influence Of Feedlot Weight On Market Lamb Peformance And Body Composition, Wallace Koester, Leon F. Bush

South Dakota Sheep Field Day Research Reports, 1970

In the last five to ten years, trimness has become very important in all species of livestock. During this time the size and scale of the market lamb has increased with a trimmer market lamb being produced. Light weight lambs tend to gain more rapidly and produce a leaner, trimmer carcass which may sell at a premium. The packer's slaughtering and processing costs are prorated on a per head basis, therefore, it costs the packer the same amount to slaughter and process a 90 pound lamb as it does a larger one. With new techniques for processing, such as prepackaging, …


Effects Of Confinement On Ewes And Lamb Performance, Roger Lind, Leon F. Bush Jan 1970

Effects Of Confinement On Ewes And Lamb Performance, Roger Lind, Leon F. Bush

South Dakota Sheep Field Day Research Reports, 1970

Mechanization in the sheep industry has been slow, while the use of confinement or semi-confinement management systems, labor saving equipment and special constructed housing has increased rapidly in the production of cattle, poultry and swine. Confinement rearing of sheep presents the opportunity to use labor saving equipment and to intensify production. By increasing the overall efficiency and stepping up the lambing percentage, we will be able to help meet the increasing operating costs.

Economics Of Sheep Production, Wallace G. Aanderud Jan 1970

Economics Of Sheep Production, Wallace G. Aanderud

South Dakota Sheep Field Day Research Reports, 1970

In December of 1968, a Sheep Symposium on Production and Management was held at Wooster, Ohio. This symposium was one of a series of symposia held throughout the country to look at problems of the sheep industry. At the meeting at Wooster, we used a standard format to look at the economics of sheep enterprises. The format that we are using today is one developed for that meeting based on sheep budgets in South Dakota Extension Circular 633, "Guidebook for Planning a Farm or Ranch Business".


Urea-Nitrate Interrelations In Sheep Under Feedlot Conditions, D. W. Hoar, L. B. Embry, H. R. King, R. J. Emerick Jan 1970

Urea-Nitrate Interrelations In Sheep Under Feedlot Conditions, D. W. Hoar, L. B. Embry, H. R. King, R. J. Emerick

South Dakota Sheep Field Day Research Reports, 1970

Three experiments were conducted to determine if measurable urea-nitrate interrelationships exist in sheep under feedlot conditions, and the extent of nitrogen utilization from urea and nitrate by sheep fed rations containing suboptimum quantities of protein. Dietary conditions imposed provided for the simultaneous adaptation of lambs to urea and sodium nitrate (experiment 1); an exposure to sodium nitrate without prior adaptation after lambs has been brought to a full feed on a ration containing urea (experiment 2); and the use of soybean meal, urea and sodium nitrate independently as protein supplements to rations providing suboptimum levels of crude protein (experiment 3).


Nitrate And Vitamin A Interrelationship In Sheep, D. W. Hoar, L. B. Embry, R. J. Emerick Jan 1970

Nitrate And Vitamin A Interrelationship In Sheep, D. W. Hoar, L. B. Embry, R. J. Emerick

South Dakota Sheep Field Day Research Reports, 1970

Several researchers have demonstrated that dietary nitrate reduced liver stores of vitamin A in ruminants. However, it has not been shown whether the effect is due to a more rapid depletion of existing vitamin A stores or to a lowered depatic deposition of the vitamin.
Two experiments were conducted to determine the effect of nitrate on plasma vitamin A, hepatic vitamin A and performance of lambs during a growing period (experiment 1) and vitamin A depletion and repletion periods (experiment 2).


Response Of Feedlot Lambs To Chlortetracycline And Sulfamethazine, L. B. Embry, R. M. Luther, C. R. Graber Jan 1970

Response Of Feedlot Lambs To Chlortetracycline And Sulfamethazine, L. B. Embry, R. M. Luther, C. R. Graber

South Dakota Sheep Field Day Research Reports, 1970

The objective of this experiment was to test the effects of chlortetracycline and sulfamethazine alone and in combination on feedlot performance and incidence of diseases of lambs weaned at an early age, shipped and finished in drylot with a high-concentrate ration.

Grazing Studies At Antelope Range A Progress Report 1964-69, James K. Lewis, W. R. Trevillyan, Marshall Haferkamp

South Dakota Sheep Field Day Research Reports, 1970

Long term grazing management studies must cover both wet and dry phases of the climatic cycle in order to provide reliable estimates of the effects of various grazing management practices on livestock production and on the range resource. Intensity of grazing studies with sheep have been conducted at the Antelope Range since 1950. A progress report of this work was published by Gartner, Lewis and Trevillyan (1965). The first phase of this study was concluded in 1962.

Flavor Preference And Stability Of A Low-Fat Dairy Spread, James Robert Miller Jan 1970

Flavor Preference And Stability Of A Low-Fat Dairy Spread, James Robert Miller

Electronic Theses and Dissertations

Low-fat dairy spread has been defined as a product which contains only dairy ingredients and has a lower fat content than the commonly used spreads, butter and margarine (5). Although some low-fat spreads have contained very little fat, most of those which have been developed during the past 30 years have contained about one-third to two-thirds as much fat as the commonly used spreads and have had a higher protein content. ·The low-fat dairy spread studied in this project contained about ten times more protein and only one-half as much fat as butter and margarine. The present day justification of …


Abnormal Milk Evaluations In Eastern South Dakota Milk Plants And Dairy Herds, Edwin J. Kleen Jan 1970

Abnormal Milk Evaluations In Eastern South Dakota Milk Plants And Dairy Herds, Edwin J. Kleen

Electronic Theses and Dissertations

For many years bovine mastitis has been a major problem for dairy producers, the seriousness of which can be measured by the volumes of literature which have been written about it as well as the economic losses incurred by the dairy industry because of it. The fact that mastitis is still a virulent disease in spite of the vast amount of research conducted on it would suggest either that the underlying causes of mastitis still are not completely understood or that the knowledge gained through research has not been presented effectively to those who need it most—namely the dairy farmer. …


Characteristics And Distribution Of Staphylococci And Micrococci Isolated From Bovine Udders, Clyde Arnold Kirkbride Jan 1970

Characteristics And Distribution Of Staphylococci And Micrococci Isolated From Bovine Udders, Clyde Arnold Kirkbride

Electronic Theses and Dissertations

Mastitis remains the most costly disease of dairy cattle. The annual loss to the dairy industry in the United States from this disease has been estimated between $225 and $500 million per year. Ninety to 95% of infectious mastitis is reported to be associated with Streptococcus agalactiae or Staphylococcus spp. Staphylococcus aureus and others of the family Micrococcaceae are reported to be the second most commonly found udder pathogens. The pathogenesis of staphylococcic mastitis remains poorly understood. Some research data have indicated that the disease is essentially contagious, and that the source of the organism is an infected udder, and …


The Effect Of Sodium Hexametaphosphate On The Palatability Of The Freeze-Dried Chicken, Ngoc Hoa Giang Jan 1970

The Effect Of Sodium Hexametaphosphate On The Palatability Of The Freeze-Dried Chicken, Ngoc Hoa Giang

Electronic Theses and Dissertations

Freeze-drying has been generally regarded as the mildest method known for drying meats, but even this process has caused undesirable changes in meat quality. The texture of rehydrated freeze-dried meat has been found to be tougher and drier than untreated meats. In addition, the meat may have a "woody" texture. Apparently something has occurred during the freeze-dry process that reduced the water-holding capacity of the meat. This has been reflected in the meat's inability to become fully rehydrated. Sodium hexametaphosphate (SHNP) has been used successfully to increase the water-holding capacity of meat and fowl. No study has been conducted to …


The Influence Of Sodium Phenobarbital On The Hepatic Adenosine Triphosphatase Activity And The Development Of This Enzyme In The Rat, Gerald H. Mettler Jan 1970

The Influence Of Sodium Phenobarbital On The Hepatic Adenosine Triphosphatase Activity And The Development Of This Enzyme In The Rat, Gerald H. Mettler

Electronic Theses and Dissertations

The purpose of this study was two-fold: {A) To obtain information concerning the influence of sodium phenobarbital on the hepatic microsomal enzyme system which reduces adenosine triphosphate in adult male and female rats; (B) To measure the development of hepatic adenosine triphosphatase activity of newborn and infant rats. Intraperitoneal administration of 30 to 150 mgm./Kq. of sodium phenobarbital for three to five days to adult male and female rats did not increase adenosine triphosphatase activity. These findings are rather pertinent since many enzyme systems are stimulated by much lower dosage levels of enzyme inducers, such as sodium Phenobarbital, over a …
