Factors Affecting The B-Vitamin Content Of Cottage Cheese, Gary Dean Reif

Open Access Master's Theses (through 2010)

The purpose of this study was to investigate the vitamin content of Cottage cheese and to study the factors which may alter the content of certain B-vitamins. The specific objectives were as follows:

1. To determine the niacin, B₆, B₁₂ and folic acid content of skimmilk and Cottage cheese and the retention of those vitamins in the curd from the milk.
2. To study the synthesis of niacin, B₆, B₁₂ and folic acid during the 16-hr setting period used in making Cottage cheese, and to determine whether the vitamin synthesis by the starter was partly responsible …

Heritability In Relation To Selection Differential In Cattle, G. E. Bradford, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

The concept of heritability as generally used, involves the assumption that additive genetic variance is a constant proportion of total variance over the entire range of phenotypes. If this assumption holds, selection response will be linearly related to selection differential. If not, prediction of selection response will not be possible from a knowledge of the phenotypic selection differential and the average proportion of additive genetic variance. Thus the validity of this assumption has a bearing on the design of efficient selection schemes for many situations. In the field of applied animal breeding, for example, this will affect such important questions …

Comparative Behavior And Relationships Of The Eiders, Paul A. Johnsgard

Papers in Ornithology

Pair-forming and copulatory displays of the four species of eiders are described and illustrated, based on observations of captive and wild specimens. Behavioral differences indicate that two genera (Polysticta and Somateria) of eiders should be recognized, and that Lamponetta should be considered a synonym of Somateria. Racial differences in the displays of Somateria mollissima mollissima and S. m. v. nigra are explained on the basis of sympatry between the latter and S. fischeri, producing selection for display divergence that has not affected S. m. mollissima. Similarities in the behavior patterns of the eiders and the …

Species Composition Within States For The 1962-63 And 1963-64 Hunting Seasons, Glen Smart

United States Fish and Wildlife Service: Publications

This paper considers the species composition of the duck kill in each State as determined by the Duck Wing Collection Surveys during 1962-63 and 1963-64 hunting seasons. Two-thirds of the annual kill was made up of mallards, black ducks, pintails, wood ducks, and green-winged teal. Mallards were the most common species taken in all Flyways except the Atlantic where the black duck was most abundant.

The American Eagles And Their Economic Status, E. R. Kalmbach, Ralph H. Imler, Lee W. Arnold

United States Fish and Wildlife Service: Publications

For centuries eagles have captured the fancy of man the world over. Because of its extensive range in the northern hemisphere, the golden eagle is the most widely known of this group of birds. Its use in falconry was the sport of kings. The frequency of its appearance in royal coats of arms indicated its importance. It is the national emblem of Germany and Mexico.

In North America the bald eagle as well as the golden eagle represents this group of powerful birds of prey. The bald eagle is strictly an American species, and the founders of the United States …

Comparative Behavior And Relationships Of The Eiders, Paul A. Johnsgard

Papers in Ornithology

One of the more controversial systematic problems existing in the family Anatidae concerns the taxonomic rank and evolutionary relationships of the four species of eiders, which are currently considered by the American Ornithologists’ Union (1957) to comprise three genera (Somateria, Lampronetta, and Polysticta) in the diving duck subfamily Aythyinae. In 1945, however, Delacour and Mayr included the eiders in a single genus (Somateria) within the sea duck tribe Mergini. At present, Delacour (1959) considers the eiders a separate tribe, Somateriini, distinct from the other sea ducks, and placed near the dabbling duck tribe Anatini. The erection …

Beef Cattle Progress Report, E. F. Frolik, H. H. Kramer

Nebraska Beef Cattle Reports

Efficiency of sugar beet farming can be improved by feeding beet top silage to livestock.

In two recent trials at the Scotts Bluff Experiment Station lambs fed unwilted beet top silage as the only roughage gained significantly faster than lambs fed corn silage.

Amounts of concentrates were comparable (Nebraska Experiment Station Quarterly, Fall, 1962).

This experiment compared the feeding value of a complete mixture of unwilted beet tops and concentrate added at the time of ensiling, with beet top silage and concentrate handled separately. A conventional corn silage and concentrate ration was used as a control.

Results showed that a …

Effect Of Amino Acid Supplementation Of Rations Containing Meat And Bone Scraps On Rate Of Gain, Feed Conversion And Digestibility Of Certain Ration Components For Growing-Finishing Swine, W. G. Luce, E. R. Peo, Jr., D. B. Hudman

Department of Animal Science: Faculty Publications

Previous work at this station (Peo and Hudman, 1962) has shown that meat and bone scraps, when fed at levels from 5 to 10% of the total ration, significantly depress rate of gain of growing-finishing swine. Similar results have been reported by Bloss et al. (1953), Terrill et al. (1954), Meade and Teter (1957), and Becker and Jensen (1961).

Predator And Rodent Control In The United States, A. S. Leopold, S. A. Cain, C. M. Cottam, I. N. Gabrielson, T. L. Kimball

United States Fish and Wildlife Service: Publications

In a frontier community, animal life is cheap and held in low esteem. Thus it was that a frontiersman would shoot a bison for its tongue or an eagle for amusement. In America we inherited a particularly prejudiced and unsympathetic view of animals that may at times be dangerous or troublesome. From the days of the mountain men through the period of conquest and settlement of the West, incessant war was waged against the wolf, grizzly, cougar, and the lowly coyote, and even today in the remaining backwoods the maxim persists that the only good varmint is a dead one. …

Geographic Distribution Of Some Species Of Trichodinids (Ciliata: Peritricha) Parasitic On Fishes, Glenn L. Hoffman, Jiří Lom

United States Fish and Wildlife Service: Publications

North American Trichodina from Carassius auratus, Lepomis cyanellus, L. macrochirus, Micropterus salmoides, and Rhinichthys atratulus have been studied by the silver-impregnation method and compared with European species. T. reticulata Hirschmann and Partsch, 1955, and T. (Foliella) subtilis Lorn, 1959, originally described from European goldfish, are herein recorded from North America also. T. fultoni Davis, 1947, from Lepomis cyanellus, Micropterus salmoides, and Rhinichthys atratulus is redescribed, and T. domerguei f. magna Lorn, 1961, described from European tench and gudgeon, is considered a synonym. A Trichodina sp. from the gills of Lepomis macrochirus is described; it is almost identical with …

Genotype And Variability In Dairy Lactation Records, L. Dale Van Vleck, G. R. Barr

Department of Animal Science: Faculty Publications

In quantitative genetics, the variation of individuals within genetic groups is commonly attributed to environment. The assumption is then made that the environmental variances are similar from one group to another. Complications arise in the application of selection index theory when this assumption is not made. The results reported here indicate that in a population of dairy records, the environmental variance is not similar from one genetic group to another. Johnson (1945) and Wadell, Van Vleck and Henderson (1960) found similar results with fewer data.

Beef Cattle Progress Report, E. F. Frolik, H. H. Kramer

Nebraska Beef Cattle Reports

Shipping fever is a respiratory disease "complex" of cattle. The disease causes extensive economic losses from death, loss of physical condition, inefficient feed utilization and treatment expense. The annual loss from this disease in the United States has been estimated to be $25,000,000.

In many respects shipping fever is similar to respiratory diseases of humans. It may occur in any season of the year, but is most common in the fall and early winter. Although any age animal may be infected recently weaned calves and feeder cattle which have just been moved from the range to feedlot are most susceptible.

Effects Of Management, Strain And Truck Shipment On Albumen Quality Of Eggs, J.L. Adams, J.L. Skinner

Department of Animal Science: Faculty Publications

Very little has been reported on changes in quality of eggs during shipment. Gwin (1952) reported a study involving more than a billion eggs purchased by the Armed Forces of the United States. U.S. Grades were determined by candling and inspection by trained inspectors from the Army Veterinary Corps and the U.S. Department of Agriculture. Quality loss was shown to be related to time in transit, distance or miles in transit and seasonal influences. No data were reported as to the relation of varying physical conditions during transit or position effects within the rail cars. Adams and Milam (1960) studied …

Studies On Neogogatea Kentuckiensis (Cable, 1935) N. Comb. (Trematoda: Strigeoidea: Cyathocotylidae), Glenn L. Hoffman, Clarence E. Dunbar

United States Fish and Wildlife Service: Publications

The cercaria of N. kentuckiensis was found in Anaplocamus dilatatus (Nitrocris d.) and Mudalia carinata. The metacercaria was found in all fishes examined from Opequon River, West Virginia, except Cottus bairdi which was also refractory to experimental infection. Two species of Centrarchidae, four of Cyprinidae, three of Salmonidae, Etheostoma flabellare, Platypoecilus maculatus, and Trichogaster trichopterus were experimentally infected. The development of the metacercari and cyst and effect on the fish are described. The histopathology initially consists of hemorrhage and muscle necrosis about the metacercaria, followed by reorganization and formation of a loose connective tissue cyst. The controversial adult names …

Index Catalogue To Russian, Central And Eastern European, And Chinese Literature In Medical Entomology, Volume 1: Diptera, George Anastes

United States Naval Medical Research Unit 3: Publications

Over the past several years a large number of references from the USSR, Eastern Europe, and China have been collected dealing with arthropods of medical importance. These references were coded on keysort cards which made it possible to index as many as fifteen subject areas on one card. The usefulness of this indexing system was evident by the number of medical entomologists who used it in searching for references in their specialty. In response to requests from workers in the United States and other countries who did not have ready access to the index. it was decided to publish these …

Behavioral Isolating Mechanisms In The Family Anatidae, Paul A. Johnsgard

Paul Johnsgard Collection

The ducks, geese, and swans present a host of species-recognition and isolating-mechanism problems that are equaled by few other groups of birds. As a family, the Anatidae have provided the greatest number of interspecific hybridization records of any avian family (see Gray, 1958, and Johnsgard, 1960a) both in captivity and under natural conditions. A surprising number of these hybrids have proved to be fertile, even when obtained between what appear to be well-marked genera. This remarkable capacity for hybridization indicates that isolating mechanisms must be operating effectively if species are to retain their integrity under natural conditions. Since genetic isolation …
