A Genetic Analysis Of Economic Characteristics Of Range Beef Heifers, Keith O. Zoellner

Electronic Theses and Dissertations

The beef cattle industry is one og the major sources of rural income in South Dakota. According to the South Dakota Crop and Livestock Reporting Services (1956), there were 1,492,000 beef cows and yearling beef heifers on the farms and ranches in South Dakota as of January 1, 1957. They also reported that sales from cattle and calves amounted to approximately 34.6 percent of the gross farm and ranch income in the state. Since the beef cattle industry is a major source of the farm and ranch income in South Dakota, any improvement in the performance of beef cattle will …

Nebraska Deer, William Bailey Jr., George Schildman, Phillip Agee, C. G. Pritchard

Nebraska Game and Parks Commission: Publications

IN COMMON with the experience of most states, Nebraska's deer herds were reduced to a very low level by excessive harvests in our early history. Most American big-game animals were overharvested in the early history of this nation because of commercialization. Buffalo were killed for their hides, deer for their meat. This slaughter continued as long as the hunter (or poacher) could sell his take at a profit. Modem game management and public opinion reversed this trend. Deer are on the way back all over America, and in some states the protection-complex was so strong that deer were restored to …

The Effects Of Low Temperature On Survival Of Rabbit Ova, Mansur Ferdows

Electronic Theses and Dissertations

In the field of animal production, genetic characteristics determine to a large extent the quality and the economy of the cattle. To hasten the wide spread dissemination of germ plasm, many commercial farmers have resorted to artificial insemination. Artificial insemination has however, only allowed for the wide spread dissemination of germ plasm from the male. If the female germ plasm could also be more easily disseminated through the highly experimental process of ova transfer, then more than the average number of offspring could be expected from a female in her life time. Because ova transplantation is in its infancy, many …

Gyrodactylus Eucaliae N. Sp. (Trematoda: Monogenea) From The Brook Stickleback, Eucalia Inconstans*, Glenn L. Hoffman, Francis M. Ikezaki

United States Fish and Wildlife Service: Publications

A new species of Gyrodactylus was observed on the skin, gills, and fins of the brook stickleback from the English Coulee, Grand Forks, North Dakota during the summers of 1953-1955. Host-specificity is usually striking in the monogenetic trematodes and since this parasite was not observed on any other species of fish from this body of water or the nearby Turtle River, it was studied in detail and is here described as a new species, G. eucaliae.

The Rabbit : An Illustrated Anatomical Guide, Edwin Chin Jr.

University of the Pacific Theses and Dissertations

This study on the anatomy of the rabbit was based on dissected material from the biological laboratories of the College of the Pacific. Because of existing errors in many of the present references to rabbit anatomy, the guide was prepared to meet the expressed need for a concise, illustrated outline of basic anatomy of the rabbit which might be used by students in an introductory course in mammalian or human anatomy. Since it is assumed that the guide would be supplemented by a dissection manual, syllabus, or textbook, textural material of such an outline is presented here in outline form.

The Relation Of Spring Bird Distribution To A Vegetation Mosaic In Southeastern Washington, Paul A. Johnsgard, W. H. Rickard

Paul Johnsgard Collection

Climax vegetation is of particular interest for study since it is the oldest and most stable vegetation of a region and should be expected to have a distinctive complement of animals. The purpose of this investigation was to observe the predilection of birds for stands representing climax plant associations in a remnant of native grassland in southeastern Washington.

The grasslands of this region were rapidly converted from grazing use to wheat production beginning about 65 years ago (Daubenmire 1942) and as a result only a few scattered remnants of native vegetation remain today. Associated with changes in vegetation there have …

Range Liverstock Nutrition And Its Importance In The Intermountain Region, C. Wayne Cook

Faculty Honor Lectures

It has been estimated that about 728 million acres or about 76 percent of the entire land area in the West is used for grazing (Stoddard and Smith 1956). In Utah about 93 percent of the land area or 48,900,000 acres is considered range land (Reuss and Blanch 1951). Although some of this range land is forested, a large area of it can be used only for grazing. Therefore, range livestock production is an important segment of western agriculture.

Before 19'00 most of the animals in the West grazed on the range all year. However, irrigation crop production has expanded …

Effects Of Water Fluctuation And Vegetation Change On Bird Populations, Particularly Waterfowl, Paul A. Johnsgard

Paul Johnsgard Collection

In recent years reclamation activities in the Columbia Basin of Washington have resulted in profound changes in the character of the entire landscape throughout this region. The present study is an attempt to clarify some of the biological effects of impoundment behind O'Sullivan Dam in the Potholes area, Grant County (Johnsgard 1955b). In this area, a large expanse of moving sand dunes and a high water table are responsible for causing the formation of numerous small water areas, or "potholes," between the dunes. The physical nature of the area and its limited potentialities have made it of little value to …
