Limnology Of Three Farm Ponds In South-Central South Dakota, Larry Kim Graham Jan 1966

Limnology Of Three Farm Ponds In South-Central South Dakota, Larry Kim Graham

Electronic Theses and Dissertations

Physical, chemical, and biological aspects of three farm ponds in south-central South Dakota were studied from June 1964 until December 1965. Maximum water temperature at the surface reached 25.2 C, while water temperatures at the bottom of the ponds were about 2 to 4C lower than the surface. Light transmission was influenced by turbidity but generally penetrated to the bottom of the ponds except during periods of cloudy ice and snow cover. Dissolved oxygen was near saturation during periods of open water. Most chemical ions in the ponds increased annually from a winter minimum to a spring maximum. Total dissolved …

Lipid And Amino Acid Studies Of Selenium Toxicity With The Rat, Mary Jane Abraham Jan 1966

Lipid And Amino Acid Studies Of Selenium Toxicity With The Rat, Mary Jane Abraham

Electronic Theses and Dissertations

Selenium exhibits unusual biological properties in that it is a micro nutrient for animals (1) and some plants (2) and yet at slightly higher levels it may be very toxic (3,4). Neither the active forms of selenium nor the mechanisms by which its biological effects are produced are well understood. Thus, many aspects remain to the investigated in this area. Franke (9), while working with the affected grain at South Dakota State College, produced the toxic symptoms experimentally. Following the discovery by Robinson (10) of selenium in toxic forages and grains. Franke (12) further deduced that plants incorporate soil selenium …

Mobility And Behavior Of Raccoons In Eastern South Dakota, George L. Geis Jan 1966

Mobility And Behavior Of Raccoons In Eastern South Dakota, George L. Geis

Electronic Theses and Dissertations

Introduction: Increasing populations of raccoons (Procyon lotor) and reports of depredation on upland game, poultry, and garden crops indicated a need for research concerning behavior, mobility, and range of raccoons. The raccoon has seemingly adapted to the dry environment of the northern agricultural plains. According to records, the original range apparently did not extend into South Dakota. Lewis and Clark did not report raccoons when they traveled along the Missouri River in 1804 and 1806 (Coues, 1893). Although Visher (1918) noted that raccoons were not rare in wooded areas along streams in western South Dakota, he made no mention of …

Poultry Pest Control, Cooperative Extension South Dakota State University Dec 1965

Poultry Pest Control, Cooperative Extension South Dakota State University

SDSU Extension Fact Sheets

Lice and mites are the major external parasites of poultry in South Dakota. They cause immediate loss in the poultry flock by decreasing weight gains and egg production, and they are carriers of disease. Lice and mire infestations — if allowed to go untreated — eventually can cause deaths in birds. Flies have become an important secondary pest of poultry housing, especially in suburban communities. Build-up of large amounts of manure and refuse under the roosts serves as an ideal fly breeding area. Flies often migrate from the poultry house to nearby dwellings and become a severe nuisance.

A Study On Baby Pig Survival, R.D. Magstadt, R.W. Seerley Nov 1965

A Study On Baby Pig Survival, R.D. Magstadt, R.W. Seerley

South Dakota Swine Field Day Proceedings and Research Reports, 1965

Nearly everyone raising pigs is aware of the high mortality rate of baby pigs during the first few days of life. It is estimated that 25 to 30 percent of all live pigs die before reaching market weight. Most of these die in early life. Approximately 75 percent of all baby pig deaths were due to three general causes: (1) small and weak pigs, (2) chilling, and (3) overlaying by the sow. The economic loss due to the death of these pigs is overwhelming. If each good pig is worth five dollars and roughly 20 to 30 million newborn pigs …

Antibiotics For Growing-Finishing Swine, R.W. Seerley, M.E. Wastell Nov 1965

Antibiotics For Growing-Finishing Swine, R.W. Seerley, M.E. Wastell

South Dakota Swine Field Day Proceedings and Research Reports, 1965

The use of antibiotics in swine rations has be come a recognized practice to the point where most swine growing-finishing rations contain them . There is evidence that certain antibiotics added to rations improve the growth rate of pigs under most conditions but not always. The most commonly reported effect of antibiotics is a more uniform growth response of the pigs. Fewer unthrifty, slow-growing individuals occur in a group of pigs, and thus the average rate of gain is increased. There is usually little or no improvement in the performance of the more rapidly growing pigs. During the past few …

A New Method Of Feeding- The Nutritious Water Method, Robert W. Seerley Nov 1965

A New Method Of Feeding- The Nutritious Water Method, Robert W. Seerley

South Dakota Swine Field Day Proceedings and Research Reports, 1965

Traditionally, swine diets have been developed by including the essential nutrients (carbohydrates, fats, proteins, minerals and vitamins) and growth supporting additives in the dry diet. Completely mixed diets have been widely accepted by the modern swine producer because they support excellent gains and feed utilization by the animals. It has been convenient and advantageous to feed these completely mixed balanced diets; however, there are some disadvantages. Cost of the diets rises as more and more mixing of ingredients is required. The additional expense is due to the equipment and labor involved in mixing the nutrients used in small quantities, called …

Ventilation For Swine Buildings, H.G. Young Nov 1965

Ventilation For Swine Buildings, H.G. Young

South Dakota Swine Field Day Proceedings and Research Reports, 1965

The trend in swine housing toward multiple farrowing systems and confinement growing and finishing units has brought about a need for an increased amount of environmental control. Close control of temperature, relative humidity, fresh air and sanitation has become a matter of prime importance. Of these factors, the control of temperature, relative humidity and fresh air thro ugh proper insulation and ventilation require the most precise planning and design in swine housing systems. Ventilation is required to remove the moisture produced by the animals as well as to control temperature and odors. A properly planned ventilation system requires an adequately …

Supplemental Lysine In Rations Or Drinking Water For Growing-Finishing Swine, R.W. Seerley, J.W. Mccarty Nov 1965

Supplemental Lysine In Rations Or Drinking Water For Growing-Finishing Swine, R.W. Seerley, J.W. Mccarty

South Dakota Swine Field Day Proceedings and Research Reports, 1965

The lysine content of corn and barley is relatively low and pigs need a higher level in their ration to meet their daily requirements. Protein sources such as soybean meal are used to provide the necessary amino acids in the ration. Since the protein sources are expensive, the quantity added in a ration is generally just adequate to meet the animal' s requirement. Most amino acids are more than adequate in rations with soybean meal, but lysine is usually on the borderline or the most limiting amino acid. Consequently, there have been many experiments conducted to improve growth rate by …

Performance Of Growing-Finishing Swine Under Different Environmental Conditions, R.C. Wahlstrom, R.W. Seerley, H.G. Young, J.E. Fredrikson

South Dakota Swine Field Day Proceedings and Research Reports, 1965

The performance of growing-finishing pigs maintained in pens with different floor construction has been studied in two experiments (winter and summer). The four types of floor construction are: completely slotted, 5CY/o slotted, 25% slotted and a sloped concrete floor with a narrow gutter across the lower end of the pen. Pits under the slotted floors accumulate the manure. In addition to floor type, a comparison has been made of number of pigs per pen and controlled and uncontrolled house temperatures. Pen size was 5 x 15 feet when 8 or 9 pigs were used per pen and 10 x 15 …

Grain Banks In South Dakota, Harlan J. Dirks Jul 1965

Grain Banks In South Dakota, Harlan J. Dirks

Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)

Grain banking is a relatively new feed merchandising technique being used by country elevators in South Dakota. In simple terms, grain banking is any kind of an arrangement whereby farmers deposit feed grain at the elevator, and later withdraw it in one form or another, generally as mixed feed. Many country elevators have shown interest in grain banking as a means of utilizing surplus storage capacity and expanding services offered to farmers. Because of this interest, information is needed to guide elevator managers in developing more efficient and uniform methods of grain banking. This study obtained information about the operating …
