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 …

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 …

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

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 …

Teenagers Teaching Nutrition: Effects On Their Own Dietary Habits, Marlys Hauck-Fenner

Electronic Theses and Dissertations

This researcher first felt the need for teenage nutrition education beyond the traditional in-class activities after teaching several years of home economics at the high school level. During discussions, students revealed that they daily consumed only small quantities of food in order to lose weight or remain slim. Diets leaned heavily towards meats and carbohydrate foods, and included very few fruits and minute quantities of vegetables other than potatoes. Students also showed a great reluctance to prepare or sample unfamiliar foods in the laboratory, especially vegetables and milk products. Discussions with other teachers showed those to be common problems in …

A Plant Growth Study Of 18 Flax (Linum Usitatissimum, L.) Genotypes, Mick Sikaenyi Mwala

Electronic Theses and Dissertations

Flax is an important oilseed cop in the United States. Limitations on seed yield have been a major concern of researchers trying to develop high yielding flax cultivators. Dybing stated that comparative studies of physiological and biochemical factors could provide necessary insight into the cause of these limitations. Comstock concluded that there was sufficient genetic variability in the Flax World Collection to meet any breeding objective. Lay et al. considered the question of what physiological parameters could be measured to identify high yielding genotypes, and when in the life cycle of a plant those parameters could be influencing seed yield …

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 …

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 …

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

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

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 …

Fat Added To Sow Gestation Diets, L. J. Kortan

South Dakota Swine Field Day Proceedings and Research Reports, 1979

Baby pigs are born with a minimal store of usable energy, primarily in the form of fat and glycogen. These stores are rapidly depleted after birth. It is generally thought that less than 15% of liver glycogen, which is the mostly is the most important store for usable energy, is present 24 hours after birth.

Beef Cattle Performance Testing, Cooperative Extension South Dakota State University

SDSU Extension Fact Sheets

Performance testing offers beef cattle breeders a way of measuring differences among animals for traits that have economic significance. The economic traits are those that contribute to production efficiency, carcass desirability, rapid growth rate, efficient use of food, regularity of reproduction, and carcass quality desired by the packer and consumer. The differences measured in these traits are inherited differently. The systematic measurement of these differences, the recording of the measurements, and the use of the records in a selection program will increase the rate of genetic improvement in a herd.

Endangered And Threatened Species In South Dakota, Alan W. Wentz, Cooperative Extension Service

SDSU Extension Special Series

"Rare" end "unusual" plants and animals have always fascinated people. Humans usually assign high values to things that are rare as opposed to things that are common. Consider. for example, the present values we assign to gold end diamonds in relation to the value we give to gravel. For the same reasons rare animals and plants have been sought after by humans. Early explorers often returned to their native lands with live or dead specimens of exotic animals. Not many years ago women in the eastern United States sought to adorn their clothing with the unusual feathers of plumed birds, …
