Effect Of Ferrous Fumarate In The Lactation Diet On Sow Milk Iron, Pig Hemoglobin And Weight Gain, T. L. Veum, J. T. Gallo, L. Dale Van Vleck, J. K. Loosli

Department of Animal Science: Faculty Publications

Two experiments involving 22 litters were conducted to study the effects of adding ferrous fumarate to the lactation diet on iron level of sow’s milk and on weight gains and hemoglobin levels of suckling pigs. Ferrous fumarate was not effective in increasing iron content of milk, when added to the lactation diet at a level of 1984 mg. of iron per kg. The increase in hemoglobin level observed at 24 days in Experiment I and at 21 days in Experiment II, in litters nursing sows fed ferrous fumarate, was due to the pigs’ obtaining a source of iron from the …

Comparison Of Heritability Estimates From Daughter-Dam Regression And Paternal Half-Sib Correlation, L. Dale Van Vleck, G. E. Bradford

Department of Animal Science: Faculty Publications

Analysis of 60,000 pairs of daughter and dam first-lactation records expressed as deviations from herd-mate averages for five breeds yielded markedly different heritability estimates from daughter-dam regression than from paternal half-sib correlation. These results suggest that 18% of the within-herd variation is due to genetic maternal effects. The same records analyzed as mature equivalent records and not as deviations but by a sire by herd model did not show this difference. Confounding between year and sire effects probably biased the intraclass correlation estimates upward in the latter analysis, since year effects were not included in the statistical model.

Heritability Estimates When Dams And Daughters Are In The Same And Different Herds, L. Dale Van Vleck, C. L. Hart

Department of Animal Science: Faculty Publications

The regression of daughter on dam deviations of Holstein first-lactation milk production from herd-mate averages was computed for 38,440 pairs of records made in the same herd and for 10,256 pairs of records where the daughter was in one herd and the dam in another. The corresponding heritability estimates were .42 and .40, respectively, which suggest an environmental covariance of .01 between records of daughters and dams in the same herd. Other analyses were conducted for dams with two daughters with records where 1) both had records in the same herd as the dam, 2) only one had a record …

Differences Among Appraisers In The New York Type Appraisal Program, L. Dale Van Vleck, R. Albrectsen

Department of Animal Science: Faculty Publications

The purpose of the New York type appraisal program is to attempt to rate type traits objectively. Approximately 34 traits are included, of which 25 are rated by the appraiser and 9 by the herd manager. This paper reports differences among 18 appraisers, including S professional judges, 7 New York Artificial Breeders' Cooperative fieldmen, and 3 other sire selection personnel all of whom rated 38 cows in a single herd. There were statistically significant differences (P ≤ .05) among appraisers for all traits. Average scores of the professionals were different from those of the fieldmen for all except six traits. …

Factors Influencing The Regression Of Corpora Lutea In The Ewe, Rabbit And Rat, H. G. Spies

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Stages in the life of corpora lutea may be divided logically into formation, function and regression. Mechanisms controlling each stage may be independent or overlapping depending on the species. Anderson et al.,(4) have pointed to lack of current evidence to allow a clear distinction between luteinizing hormone (LH) and luteotropic hormone (LTH) in farm animals. Initial LTH release is probably sufficient to form and maintain the corpora lutea for the normal estrous cycle (Aldred et al., 1). Maintenance of corpora lutea for the normal duration of an estrous cycle in hypophysectomized ewes (Denamur and Mauleon, 6) and sows (du Mesnil …

Rural Zoning In Nebraska, Donald R. Witt

Nebraska Law Review

The purpose of this comment is to examine the rural problems in Nebraska and the possible solutions available through zoning. Zoning has evolved from the police power reserved to the individual states by the United States Constitution, subject to certain constitutional limitations and safeguards. Thus, to determine the absolute limits of valid zoning legislation, an examination must be made of the United States Supreme Court's interpretation of the police power. Since zoning is a power exercised by the individual states, however, the absolute limits allowed by the federal constitution may be further narrowed and constricted by state law, as interpreted …

Mechanisms Controlling The Formation And Persistence Of The Corpus Luteum, L. L. Anderson, R. M. Melampy

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Mechanisms which control formation of corpora lutea during the estrous cycle, and particularly factors affecting their persistence and regression in various reproductive stages, have been of considerable interest to physiologists concerned with developing methods for control of the estrous cycle in domestic animals. Some recent reviews on control of ovarian function are those by Chester Jones and Ball (30), Anderson et al. (9) and Short (121).

The Lifespan Of Corpora Lutea Induced During The Luteal Phase Of The Estrous Cycle In Swine., B. N. Day

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

A more complete understanding of the mechanisms involved in the function and maintenance of the corpus luteum would be very useful in developing more effective methods of controlling the estrous cycle in farm animals. Various types and classes of experimental animals have been utilized in an effort to define the factors causing the persistence of the corpus luteum. In swine, several different experimental approaches have been made in an attempt to extend, experimentally, the functional lifespan of the corpus luteum in non-pregnant animals. Less frequently, attempts have been made to induce premature regression. In general, the procedures used to induce …

Harold W. Manter Laboratory of Parasitology: Library Materials

Summary

The development of Nuttallia tadzhikistanica in the larvae and nymphs of Hyalomma anatolicum was followed. In the first hours after the larvae had begun blood sucking on infected specimens of Meriones erythrourus, Nuttallia which had got into the intestire of the tick, leave erythrocytes and multiply by division into two or four individuals. Two or four hours later, mono-nuclear trophozoites occur in the haemocoel of the tick. Here their multiple division occurs. Multinucleated developmental stages of Nuttallia occur in the haemocoel during 24 hours after the larvae become detached from the host. The multinucleated stages break down into …

Density-Gradient Centrifugation: Non-Ideal Sedimentation And The Interaction Of Major And Minor Components, Myron K. Brakke, J. M. Daly

Department of Plant Pathology: Faculty Publications

A small amount of southern bean mosaic virus was contained in a narrow zone after density-gradient centrifugation, but in a much wider zone after centrifugation with a large amount of a second virus. Zone-spreading of a major component by non-ideal sedimentation in density-gradient centrifugation can cause zone spreading of a minor component that the major component overlaps.

Two New Species Of Plistophora (Microsporidea) From North American Fish With A Synopsis Of Microsporidea Of Freshwater And Euryhaline Fishes, Robert E. Putz, Glenn L. Hoffman, Clarence E. Dunbar

United States Fish and Wildlife Service: Publications

Two new species of Microsporidea, Plistophora salmonae from steelhead and rainbow trout (Salmo gairdneri) and Plistophora cepedianae from gizzard shad (Dorosoma cepedianum) are described. Schizonts to spores of P. cepedianae were found at one time within the same cyst, while only sporonts and spores of P. salmonae were found within the cyst. An illustrated synopsis of the known Microsporidea of freshwater and euryhaline fishes is given.

Eimeria Aurati N. Sp. (Protozoa:Eimeriidae) From Goldfish (Carassius Auratus) In North America, Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

In March, 1962 this laboratory received some goldfish for disease diagnosis from Mr. Richard Rice, Mercersburg, Pennsylvania. Seven of 29 fish examined were infected with Eimeria. These fish had long, whitish, opaque fecal casts hanging from the anus. The casts were composed almost entirely of oocysts. When shed, they sank to the bottom and looked somewhat like "spent" tapeworms (Figs. 1, 2). The infected fish were very lethargic and their intestines were swollen with contained fluid. Although I believe that the Eimeria is pathogenic, a heavy infection of other parasites made this difficult to determine. These fish had apparently …

Roles Of Hypothalamus And Hypophysis In The Control Of The Estrous Cycle, A. V. Nalbandov

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The interrelation between the hypothalamus and the anterior pituitary gland has been firmly established. It is not the intention of this report to review the literature on this extensive subject. Such reviews are available in "Advances in Neuroendocrinology" (Nalbandov, 2), and since the time of this publication many papers on this subject have appeared in current journals. For the purposes of the present discussion a few fundamental facts will be restated, but the major part of my presentation will deal with my own views of the research areas which should be of special interest to animal scientists concerned with phenomena …

Hormonal Control Of Reproductive Activity In The Ewe, J. F. Wagner

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

There are many advantages which result from synchronizing the estrous period in a ewe flock. In situations where the ewes are not hand bred to the ram, the synchronization of estrus makes the application of artificial insemination (AI) techniques more efficient. Detection of estrus usually is more reliable in a synchronized flock. Only 3 to 4 days are needed to detect estrus in 90 percent of a synchronized flock, whereas 16 to 18 days are normally required. This allows the AI technician to plan the number of breedings and have semen available. When hormones are given in the feed, an …

A Legal-Economic Critique Of Nebraska Watercourse Law, Clayton K. Yeutter

Nebraska Law Review

Nothing is more emotion packed than a discussion of ways and means to allocate a resource that is essential to the maintenance of human life. Yet the scarcity of water in many parts of our nation makes such a discussion imperative. Although Nebraska's landscape is dotted with innumerable creeks and streams, the state's tremendous irrigation developments have long since created water disputes and a legal system for adjudicating them. This article will attempt to show that from a legal-economic viewpoint at least some changes are long overdue.

"The Battle Of The Experts": A New Approach To An Old Problem In Medical Testimony, Larry W. Myers

Nebraska Law Review

The testimony of medical experts is essential in establishing the extent of a plaintiff's injuries in personal injury litigation. When conflicting or contradictory medical testimony is presented, a phenomenon arises which often attains such noticeable proportions that it has been dramatically labeled "the battle of the experts." In several jurisdictions, judicial, legal, and medical groups have collaborated to create programs aimed at resolving or minimizing these courtroom conflicts. This study seeks to ascertain whether such a program would promote the administration of justice in Nebraska.

Peroxidase And Polyphenoloxidase Activities And Free Ninhydrin-Positive Substances In Underground Buds Of Ironweed And Leafy Spurge, W. G. Monson, Francis A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

Peroxidase activity in extracts of underground buds of ironweed and leafy spurge was at the lowest level during the period of dormancy in both species, and increased when dormancy was broken. Polyphenoloxidase activity of bud extracts was high for ironweed and very low for leafy spurge, and showed no relationship with dormancy in either species. Ninhydrin-positive substances generally and sulfur-containing amino acids in particular increased during the dormant period.

Life Cycle And Development Of Prosthorhynchus Formosus (Van Cleave, 1918) Travassos, 1926, An Acanthocephalan Parasite Of Birds, Gerald D. Schmidt, O. Wilford Olsen

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The life cycle of Prosthorhynchus formosus (Van Cleave, 1918) Travassos, 1926 is presented. The terrestrial isopods Armadillidium vulgare, Porcellio laevis, and P. scaber served as experimental intermediate hosts, and chickens and turkeys as experimental definitive hosts. After ingestion of the eggs by the isopod, the acanthor emerges from its shells within 15 minutes to 2 hours, enters the gut wall of its host, and remains there 15 to 25 days. It then migrates to the hemocoel and develops through the acanthella stage to the infective cystacanth by the 60th to 65th day of infection.

The Variance Of Intraclass Correlation Involving Groups With One Observation, L.A. Swiger, W.R. Harvey, D.E. Everson, K.E. Gregory

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

An approximate formula is derived for the variance of intraclass correlation when unequal numbers of observations per group occur. The effect on the variance of t of adding groups with single observations is examined using the formula and results obtained by empirically generating data on a computer. The empirical results indicate that the approximate formula is satisfactory over the range of numbers used.

Adding a group with fewer than the average number of observations per group tends to reduce Vt by increasing the degrees of freedom for groups by one, but tends to increase Vt by decreasing the average precision …

Studies On The Helminth Fauna Of Alaska. Xli. Observations On Cestodes Of The Genus Diplogonoporus Lönnberg, 1892 (Diphyllobothriidae), Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The study of a collection of cestodes assigned to the genus Diplogonoporus Lönnberg, 1892 disclosed but two species, D. balaenopterae Lönnberg, 1892, and D. tetrapterus (von Siebold, 1848) (provis.). These cestodes occur characteristically in marine mammals but occasionally are found in terrestrial hosts; D. balaenopterae is recorded for the first time from the domestic dog, and it is concluded that D. grandis (Blanchard, 1894), from man, is conspecific with D. balaenopterae. The latter species is recorded for the first time from the humpback whale, Megaptera novaeangliae (Borowski). The relatively small D. tetrapterus, a common parasite of the Steller …

Calcium Ion Requirement For Proliferation Of Bacteriophage Φμ-4, Fred Shafia, T.L. Thompson

Papers in Microbiology

SHAFIA, FRED (University of Nebraska, Lincoln), AND T. L. THOMPSON. Calcium ion requirement for proliferation of bacteriophage Φμ-4. J. Bacteriol. 88:293-296. 1964.-Divalent ions are essential for proliferation of phage Φμ-4. Small amounts of citrate interfere with efficient adsorption of phage to the host cells. Penetration of phage material into the cell is strictly dependent on divalent ions and is inhibited by low levels of citrate. Inhibition of infection can be partially reversed, in early latent period, by calcium ions. Synthesis of new phage particles is also dependent on divalent ions. Addition of citrate to infected cell suspensions significantly reduced the …

Biochemical Changes During The Growth Of Fungi: I. Nitrogen Compounds And Carbohydrate Changes In Penicillium Atrovenetum, David Gottlieb, James L. Van Etten

Department of Plant Pathology: Faculty Publications

Changes in the biochemical constituents of cells were studied during the growth and development of Penicillium atrovenetum. Growth of the fungus, as measured by the dry weight, could be divided into four phases: lag, log, stationary, and death. The percentages of total nitrogen, cold trichloroacetic acid-soluble nitrogen, ribonucleic acid (RNA), and protein increased to a maximum during the lag phase, and subsequently decreased as the fungus aged. The percentage of deoxyribonucleic acid (DNA) was always slightly higher in the spores than in the mycelium. The DNA in the mycelium decreased in the lag phase, and then increased slightly to …
