The Relative Efficiency Of Artificially Stack-Dried Alfalfa Hay Versus Field-Cured Alfalfa Hay In Promoting Growth Of Dairy Heifers At Huntley, Montana, John A. Stocking

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Roughage is the cheapest source of nutrients for herbivorous animals, and alfalfa is the best of the roughages because animals consuming alfalfa as a major part of their diet have an adequate supply of protein, energy, and a considerable proportion of needed vitamins.


Age And Growth Of The Green Sunfish Lepomis Cyanellus Rafinesque In Northern Utah, Young E. Wright May 1951

Age And Growth Of The Green Sunfish Lepomis Cyanellus Rafinesque In Northern Utah, Young E. Wright

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The green sunfish Lepomis cyanellus Rafinesque is a member of the sunfish family Centrarchidae. Curtis (1949) states that all members of the sunfish family are native only to North America, and are primarily warm-water fish. According to Jordan and Evermann (1934) the green sun-fish is generally abundant in all suitable waters from central Ohio and Indiana to the Rio Grande. Forbes and Richardson (1920) give the general distribution of the green sunfish to be from the Great Lakes to Mexico, the Mississippi Valley, and everywhere in small sluggish streams except east of the Alleghanies and in Canada. The green sunfish …

The Utilization Of Food Elements By Growing Chicks. Xiii. The Effect Of Additions Of Dehydrated Alfalfa Meal To High Corn Chick Rations, C. W. Ackerson, R. L. Borchers, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Feeding trials were conducted on three groups of chicks in eight lots receiving a growing mash containing dehydrated alfalfa meal at levels of 2, 3, 4, 5, 6, 9, 10, 12, and 15 per cent. Comparisons were not made simultaneously but no general trend toward growth depression was evident in comparable lots. In addition duplicate trials of four lots of newly hatched New Hampshire chicks were made on pelleted rations carrying 0, 2, 4, and 6 per cent of a good quality dehydrated alfalfa meal. The chicks were all fed accurately known amounts of the pelleted rations for six weeks. …

A Study Of Bovine Noseprints, Morris W. Hirsch Jan 1951

A Study Of Bovine Noseprints, Morris W. Hirsch

Electronic Theses and Dissertations

The breed association are continuously confronted with the problem of properly identifying animals for registration. The method of identifying the broken color breeds, such as Guernseys, Holsteins, and Ayrshires, is by a sketch of the color patterns which accompanies the application for registration. This has been fairly successful, but due to the poor drawing ability of the applicant approximately twenty percent of animal markings and sketch do not resemble each other to establish identity. The solid colored breeds use brands or tattoo marks in the ear which are not entirely satisfactory since these are artificial and can be applied in …


The Status Of Beavers In The Delta Area Of The San Joaquin River, San Joaquin County, California, 1950-1951, Delbert David Cram Jan 1951

The Status Of Beavers In The Delta Area Of The San Joaquin River, San Joaquin County, California, 1950-1951, Delbert David Cram

University of the Pacific Theses and Dissertations

The term “delta area” refers to a region roughly 40 miles long and 15 miles wide situated 65 miles east of San Francisco Bay where the San Joaquin and Sacramento Rivers join and enter Suisun Bay. The waterways in this area are fresh water from these rivers, but they are affected by the ocean tides and to some extent by the salinity of the ocean water. The rgeion ecompasses about 507,000 acres, most of which has been reclaimed for agricultural purposes by the construction of levees to contain the tides and high waters. The word “islands” is used locally to …

Bear River: A National Wildlife Refuge, Vanez T. Wilson, Rachel Carson Jun 1950

Bear River: A National Wildlife Refuge, Vanez T. Wilson, Rachel Carson

United States Fish and Wildlife Service: Publications

In the autumn of 1824 a buffalo-hide canoe drifted down the Bear River to its mouth in the Great Salt Lake of Utah. Within sight of that vast inland sea, Jim Bridger must have paused in amazement. Everywhere he looked-in the sky, on the open water, over the marshy borders of the lake-there were birds. It is said that the famous explorer of the western wilderness brought back reports that he had that day seen "millions of ducks and geese."

The Bear River marshes were soon to know years when their waterfowl were numbered, not by millions, but by thousands; …

Some Observations On The Embryology And The Weberian Apparatus Of Catostomus Ardens (Jordan And Gilbert), H. Ronald Frogley May 1950

Some Observations On The Embryology And The Weberian Apparatus Of Catostomus Ardens (Jordan And Gilbert), H. Ronald Frogley

Theses and Dissertations

The purpose of this study is to add to our knowledge of the embryology and osteology of the Weberian apparatus as found in the sucker, Catostamus ardens J. & G. ot Utah Lake. Observations were made on the embryological development for twenty one days. This information has been discussed and pictures showing the development included. The literature on the osteology ot the Weberian apparatus was reviewed and it is believed that this study presents the first descriptions of the bones of this species. The ossicles were found to be comparatively stable within species indicating some taxonomic value. More study is …


Peromyscus Populations As Related To Seasons And Vegetative Types At The Hardware Ranch, Cache County, Utah, George Cleveland Turner Jr. May 1950

Peromyscus Populations As Related To Seasons And Vegetative Types At The Hardware Ranch, Cache County, Utah, George Cleveland Turner Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Members of the genus Peromyscus, White-footed Mice, are known to occur in nearly all habitats of North America. Because of their numerical abundance and widespread distribution, these mice are extensively used in the study of the dynamics of animal populations. Thus, information perteining to the local distruibution and activities of these mice is of value to the more comprehensive studies that are being carried out in the field of zoological research.


A Survey Of Plant Parasitic And Associated Species Of Nematodes In The Carrot Producing Area Of Cedar Valley, Iron County, Utah, Paul R. Fitzgerald May 1950

A Survey Of Plant Parasitic And Associated Species Of Nematodes In The Carrot Producing Area Of Cedar Valley, Iron County, Utah, Paul R. Fitzgerald

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plant parasitic nematodes have long been known to cause extensive crop losses through reduced yields, shortened productive life, or lowered value of produce. The rood knot nematode, Heterodera marioni, is cosmopolitan. It destroys crops and causes economic losses equal to those of any other plant parasitic species. in 1948 this nematode caused an estimated loss to the carrot raising industry in Iron County, Utah of approximately $15,000. No estimates for the years prior to 1948 are available; however, reports of the county agent (14) for Iron County show that carrot production in the Cedar Valley is decreasing, and is …


Hive And Field Mortality Of Honey Bees In Northern Utah Due To Effects Of Certain Ecological And Chemical Factors, Shih Chun Ma May 1950

Hive And Field Mortality Of Honey Bees In Northern Utah Due To Effects Of Certain Ecological And Chemical Factors, Shih Chun Ma

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The honey bee is the most important pollinating insect in Utah, because various important crops such as fruits, legumes, and vegetable seed crops depend chiefly on it for pollination. In the past, honey bees have suffered repeated severe death losses through contact with arsenic and other agricultural chemicals. Recently the newer insecticides, such as DDT, chlordane, parathion, benzene hexachloride, lindane, toxaphene, and several kinds of miticides have further complicated the problem of bee survival. In addition, natural enemies such as predators and parasites and some unfavorable environmental conditions, including unfavorable temperature and humidity, wind, storm, and other changeable weather conditions, …


A Comparative Histological Study Of The Adrenal Gland Of Native Rabbits, Ernest I. Gonzalez May 1950

A Comparative Histological Study Of The Adrenal Gland Of Native Rabbits, Ernest I. Gonzalez

Theses and Dissertations

A review of the literature shows that extensive work has been done on the morphology and histology of the adrenal gland of the domesticated rabbit, but it appears that little or no work has been done on other members of the order Lagomorpha. Approximately one hundred specimens of rabbits of various ages and sizes, and of both sexes, were collected over a period of nine months. All adrenal glands were fixed by immersion and were embedded in paraffin. The majority or the glands were sectioned at eight or twelve miora, and were stained with Mallory's triple stain. This investigation shows …

Harvest Of Wild And Stocked Fish From The Logan River Drainage, Louis S. Pechacek

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Logan River heads in the southeastern corner of Franklin County, Idaho, and runs in a south and westerly direction. It enters the state of Utah through the northern boundary in the northeast corner of Cache County. The main stream is fed by two tributary streams which head in separate directions a few miles apart. The Franklin Basin branch is the main contributing tributary while the Beaver Creek branch is nearly as large.

A Comparative Anatomical Study Of The Digestive Systems Of The Desert Jack Rabbit And The Pika, Dale Stanley Rupert Feb 1950

A Comparative Anatomical Study Of The Digestive Systems Of The Desert Jack Rabbit And The Pika, Dale Stanley Rupert

Theses and Dissertations

It is the purpose of this study to make gross and histological comparisons of the various segments of the intestinal tracts of the jack rabbit and the pika. The two animals used for this study were the desert jack rabbit (Lepus Californicus deserticola Mearns), and the pika (Ochotona princepts uinta Hollister). The jack rabbits were found only in the desert valleys and low foothills in the areas studied. These areas are typically open bush or sage brush types of communities. The pikas were restricted to certain high rockslides in this region. These areas are described more completely in the section …
