The Effect Of Ferric-Nitrilotriacetic Acid On Selected Hemogram Parameters Of Gestating And Lactating Swine And Their Offspring, Thomas Allen Heirigs Jan 1980

The Effect Of Ferric-Nitrilotriacetic Acid On Selected Hemogram Parameters Of Gestating And Lactating Swine And Their Offspring, Thomas Allen Heirigs

Electronic Theses and Dissertations

Ever since man has moved to confinement farrowing of swine, the problem of iron-deficiency in baby pigs has increased. The problem can be partially alleviated by various treatments which can be employed by the swine producer. However, many of these treatments stress to the young piglet and involve much time and labor, which may not be available during parturition. A beneficial tool to the porcine producer would be the elimination of both the stress placed on the neonatal pig and of the extra labor providing a hematinic which would be administered prepartum to the dam. The hematinic employed must be …


Variability Of Factors Influencing Stand Establishment In Green Needlegrass Populations From Western South Dakota, Terril J. Heilman Jan 1980

Variability Of Factors Influencing Stand Establishment In Green Needlegrass Populations From Western South Dakota, Terril J. Heilman

Electronic Theses and Dissertations

In recent years, there has been an alarming conversion of rang-land to cropland in western South Dakota. More importantly, much of this increase in cropland has resulted in the plowing of large areas of land where the soils are unsuited or only marginally suited to continuous cultivation. During the period from 1967 to 1975, the extent of this trend represented a net increase of about 200,000 of class IV soils, which are used for the production of annual crops. Historically, such unwise expansions of cropland to land areas that are susceptable to severe wind and water erosion have resulted in …


Summer And Fall Ecology Of Gray Patridge In Eastern South Dakota, Jerry W. Hupp Jan 1980

Summer And Fall Ecology Of Gray Patridge In Eastern South Dakota, Jerry W. Hupp

Electronic Theses and Dissertations

Gray partridge (Perdix perdix) nesting biology, summer and fall habitat utilization, home range, and food habits were studied in Brookings County, South Dakota, during 1978-79. Data were collected on a 62 km² study area 16 km northeast of Brookings. Nesting habitats, success, and clutch size were determined from 44 randomly located nests. Most nests (91%) were in grassy roadsides and fencerows. Few birds nested in cover dominated by legume vegetation. Average clutch size of completed nests was 17.8 eggs and nest success was 37%. Mammalian predation was the major cause (50%) of nesting failure. Gray partridge habitat utilization was determined …

Electronic Theses and Dissertations

The food habits of bluegills (Lepomis macrochirus), black bullheads Ictalurus melas), and muskellunge (Esox masquinongv) in the Big Stone Power Plant cooling reservoir were studied from January through December 1979. The diet of 794 bluegills >50 mm TL was dominated by vegetation, planktonic crustaceans, dipteran larvae and pupae, and fishes: 214 bluegills < 50 mm TL fed primarily upon chironomid larvae and pupae and cladocerans. There was a significant difference (P50 mm. This was determined by Spearman rank correlation coefficients based upon percent number and percent volume of food items, and mean number of taxa per stomach. Both bluegill length-groups positively selected Chydorinae, ostracods, Caenis spp. larvae, chironomid pupae, and Physa spp., while they negatively selected cyclopoid copepods, Ceriodaphnia spp., and Tanypodinae larvae. Chironomid larvae were positively selected by bluegills mm, but were negatively selected by those >50 mm. Fishes and chironomid larvae were the major food items of 105 black bullheads >120 mm TL; fishes and filamentous algae were the dominant food items of 146 bullheads 5120 mm. Ostracods and dipteran pupae were positively selected, while Tanvpodinae and Chironominae larvae were negatively selected. Chydorinae, …

Feeding Value Of High Protein Oat Silage Versus Corn Silage For Dairy Cows, Tilahun Sahlu

Electronic Theses and Dissertations

Corn accounts for 80% of the total silage production in the United States while oats ranks second as a feed grain crop. Oats are a major crop in areas of the world where temperatures are cool and short growing seasons are not well suited for corn production. South Dakota is the leading oat producing state in the nation with 1. 68 million kilograms of oats produced annually. Oats play an important roll as animal feed because among common cereals in the United States it ranks highest in both protein and lysine content. Due to the wide genetic diversity of oat …


The Effect Of Prostaglandin F2-Alpha On Synchronizing Estrus In The Ewe, L Dean Churchill Jan 1980

The Effect Of Prostaglandin F2-Alpha On Synchronizing Estrus In The Ewe, L Dean Churchill

Electronic Theses and Dissertations

Synchronization of estrus has been attempted by using hormone or hormone-like substances to bring females into estrus simultaneously. The objective of a synchronization program is to manipulate the reproductive process so that all females may be bred during a short pre-defined interval with normal fertility at this breeding. The concept of estrus control and synchronization is intriguing, offering the possibility of more uniform offspring, better use of facilities and labor, concentration of parturition and, in particular, the better utilization of outstanding sires through artificial insemination. The breeding season is the period during which ewes come into heat and will receive …

Stand Densities Of Interseeded Alfalfa During The Initial Years Of Establishment And The Effect Of Applied Nitrogen And Phosphorous On Five Selected Grasses, Levi Mudogo Akundabweni

Electronic Theses and Dissertations

This study was conducted to test the feasibility of establishing alfalfa (Medicago sativa L.) in the semi-arid grasslands of north central and north western South Dakota, as a means of pasture renovation. The north central and northwestern South Dakota regions are, for the most part, native grasslands. The yield potential of these resources is primarily limited by lack of adequate precipitation. Not much research has been done in these regions to establish the magnitude of severity of factors such as nitrogen limitation and pasture and range diseases, which may, separately or in combination with soil moisture, be limiting yield potentials …


A Survey Evaluation Of South Dakota Beef Cattle Production, Vernon Dooley Jan 1980

A Survey Evaluation Of South Dakota Beef Cattle Production, Vernon Dooley

Electronic Theses and Dissertations

The beef industry is of paramount importance to the economic activity of South Dakota. Therefore, it is essential that information be made available which can serve as a guide to the development of increasingly more efficient beef production systems. Since total pounds of weaned calf represent the salable product of cow-calf operations, this is the characteristic of primary interest to producers and researchers. Fertility of the breeding herd, livability of calves and weaning weight of calves are all components of this profit-determining characteristic. Problems of low fertility are difficult to study, especially under range conditions were many of the nation’s …

Host Responses Of Calves To A Group 5 Bovine Herpesvirus, Linda A. Krogman Jan 1980

Host Responses Of Calves To A Group 5 Bovine Herpesvirus, Linda A. Krogman

Electronic Theses and Dissertations

Bovine respiratory disease (BRD) complex is of substantial economic importance to cattlemen in the United States. An estimated 40-80% of all cattle diseases involve the respiratory system. Although cattle may recover, cost of treatment and loss in production make respiratory disease an important factor to consider in the cattle industry. IN 1974, 407,000 yearling feedlot cattle in Colorado were surveyed for the causes of illness and death. The morbidity was 5.1% with a case mortality of 18.9%. Approximately 75% of the clinical diagnosis and 64% of the necropsy findings indicated respiratory tract diseases. Viruses are obligate intracellular parasites that must …


The Effectiveness Of Aeration And Potassium Permanganate Oxidation And Filtration On Removal Of Iron And Manganese From Ground Water, Steven J. Quail Jan 1980

The Effectiveness Of Aeration And Potassium Permanganate Oxidation And Filtration On Removal Of Iron And Manganese From Ground Water, Steven J. Quail

Electronic Theses and Dissertations

The United States Public Health Service (USPHS) established water quality standards in 1946 and revised them in 1956 and 1962. In these standards the maximum recommended concentrations of iron and manganese were 0.03 and 0.05 mg/l respectively. Because trace amounts of these elements are essential for proper nutrition of both plants and animals, the recommended limits are not based on any physiological or environmental considerations. Rather, the presence of iron and manganese in water is objectional because the precipitation of these metals alters the appearance of the water, turning it a turbid yellow brown to black. The Brookings, South Dakota …


Potential Industry Possibilities For South Dakota Indian Reservations, Yus Rusman Jan 1980

Potential Industry Possibilities For South Dakota Indian Reservations, Yus Rusman

Electronic Theses and Dissertations

Research studies covering manufacturing growth in more than 245 non-metropolitan communities (ones with less than 50.000 population) across the U.S. indicate that new industries may generate employment and earnings in communities where the industries are located, but net fiscal gains to local governments and school districts may be more modest. And, in some cases, elements of the local public sector may incur cost increases exceeding tax and other revenue increases. Dobbs felt that communities should not be discouraged by these findings. Instead they should invest some time and effort in examining two questions. The first question pertains to the examination …

Nesting And Brood Rearing Ecology Of The Vancouver Canada Goose On Admiralty Island Southeast Of Alaska, Charles S. Lebeda Jan 1980

Nesting And Brood Rearing Ecology Of The Vancouver Canada Goose On Admiralty Island Southeast Of Alaska, Charles S. Lebeda

Electronic Theses and Dissertations

Nesting and brood rearing biology of Vancouver Canada geese (Branta canadensis fulva) was studied in 1978 (preliminary) and from April-August 1979 in Seymour Canal, Admiralty Island, Alaska. Geese used trees for perching during the incubation period (24 April-7 June) and use was significant (P < .0001) for early morning hours. This behavior is considered unique among all Canada goose subspecies. An average of 86.3 search hours were conducted for each of 19 active nests located in 1979. Seven additional nests from previous years were also located. Twenty-two nests were located in forest habitat •. All forest nests were in association with vegetation similar to vegetation described for U.S. Forest Service classification of F4 and F5 (poorly drained) soil types. Mean clutch size was 4.4 ± 1.3 eggs. Mean egg length and width were 86.1 mm± 3.14 and 56.4 mm± 2.76, respectively. Success of all nests hatching at least one egg was 55.6%. Egg hatching success of successful nests was 95.7%. Total hatching success of all eggs was 62.0%. Forest habitat was used extensively for brood rearing. Broods generally avoided large bodies of water. Single family broods were found most often in forest habitat while creches were more common in meadows and intertidal zones. Breeding adults and goslings were comparatively less vocal in the forest. Goslings less than 2 weeks of age used forest habitat extensively and shifted to forest edge and intertidal zones with age. Forest habitats, rather than open water, were used as escape cover by breeding adults and broods. Nesting and brood rearing habitat was similar, thus, nest site selection may be closely tied to requirements for brood rearing habitat. Molting, non-breeding or unsuccessful breeding geese also used forest habitat freely and avoided observers by fleeing into the forest. Use of habitat compared to tide stage was significant (P < .0001) and may be a function of availability. Habitat use compared to daily time periods appeared to reflect feeding activity peaks in early morning and late afternoon. Adult geese primarily used the intertidal zone during pre-incubation; the grassy intertidal zone was used more during incubation and post-incubation. Skunk cabbage (Lysichiton americanum) comprised 23.8% aggregate of foods utilized and appeared to be the most important food during brood rearing. Goslings and molting geese also utilized sea lettuce (Ulva spp.) and blueberry (Yaccinium spp.) berries. Plant matter comprised the bulk of food items.


Partitioning Energy Requirements Of Angus, Charolais And Reciprocal Cross Cows, Vernon L. Anderson Jan 1980

Partitioning Energy Requirements Of Angus, Charolais And Reciprocal Cross Cows, Vernon L. Anderson

Electronic Theses and Dissertations

Increasing energy costs have stimulated more interest in efficient use of our natural resources. Utilization of energy in agricultural enterprises needs to be critically evaluated for economic survival of the enterprise. Feed energy required for beef production comes largely from harvested and unharvested forage and grasses constitute a high proportion of the costs of maintaining a cow. These costs have increased along with other production inputs. Beef cattle producers need to know how total feed energy is utilized in order to increase their efficiency. Cow herd efficiency is extremely important, especially the energetic efficiency of various size groups. Knowing the …


Isolation And Identification Of Obligately Anaerobic Bacteria From Bovine Lung Abscesses, Steven Lee Daniel Jan 1980

Isolation And Identification Of Obligately Anaerobic Bacteria From Bovine Lung Abscesses, Steven Lee Daniel

Electronic Theses and Dissertations

For many years, the role of anerobic bacteria in human disease was considered important only in such clostridial diseases as gas gangrene, botulism and tetanus. In the last 10 years, however, the development of new methods to isolate and identify anaerobic bacteria has established the pathogenic role of non-sporeforming anerobic bacteria in a wide variety of clinical infections in humans. Bacteroides fragilis is now known to account for approximately one fourth of all anerobic bacteria isolated from human clinical specimens. Recent advances in anaerobic bacteriology likewise have established that anaerobic bacteria are found as normal flora on the skin and …

The Use Of Remote Sensing Techniques To Predict Beef Carcass Cutability, William R. Lloyd

Electronic Theses and Dissertations

In the beef industry today, it is necessary for the beef packer to slaughter and sell his product, whether as boxed beef or carcass beef, as quickly as possible. Costs of labor, equipment, land, etc., as well as perishability of the end product, demand quick movement of fresh beef from the packer to the consumer. The present USDA beef grades attempt to measure the expected palatability of the end product, demand for quick movement of fresh beef from the packer to the consumer. The present USDA beef grades attempt to measure the expected palatability and yield of boneless, closely trimmed …


The Effects Of Acute Ammonia Toxicity On Certain Blood Chemistries In Sheep, Gayleen Riedemann Jan 1980

The Effects Of Acute Ammonia Toxicity On Certain Blood Chemistries In Sheep, Gayleen Riedemann

Electronic Theses and Dissertations

Protein has always been in short supply in the world. This will be even more evident when the world’s population reaches the projected 5.8 billion by the year 2000. Rosenfeld noted that not only will there be more mouths to feed, but there is also a decrease in cropland due to increased housing and industry. For these reasons, along with the monetary benefits, urea has been added to feeds for ruminants to prevent the waste of valuable protein. The Board on Agriculture and Renewable Resources cited several factors which may cause urea toxicity to develop: (1) lack of an adequate …


The Effects Of Sex And Hormonal Implant On Carcass Characteristics And Palatability, J. David Stout Jan 1980

The Effects Of Sex And Hormonal Implant On Carcass Characteristics And Palatability, J. David Stout

Electronic Theses and Dissertations

Consumer demand for beef has undergone a number of dramatic changes during recent years. Consumers are expressing a preference for reasonably priced beef cuts with a high proportion of lean in relation to fat. Increasing demand for ground beef and steaks has prompted the meat industry to look at the use of a variety of production methods. The hotel, retail and industrial trades utilize large amounts of ground beef and restructured steaks. Future production may be geared toward making ground beef from chuck, foreshank, brisket, short plate, flank and round, with the desire to sell the rib meat and short …

The Influence Of Frame Size On Growth And Carcass Characteristics In Swine Taken To Heavy Weights, Wayne Vanderwert Jan 1980

The Influence Of Frame Size On Growth And Carcass Characteristics In Swine Taken To Heavy Weights, Wayne Vanderwert

Electronic Theses and Dissertations

The current and somewhat controversial trend in swine selection is in the direction of a larger framed, later maturing animal. One goal of producers in changing to this type of animal is to produce a hog with more marketing flexibility, that is, a hog that may be carried to heavier weights without becoming over fat or that could be marketed at lighter weights and produce a very lean, muscular carcass. Excess fat is an unnecessary product in the meat animal industry that is expensive to produce from a feed efficiency standpoint. Research discussed later clearly indicated that changes in feed …
