Comments And Conclusions Concerning Studies On Estrous Control In Domestic Animals, H. H. Cole

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

Let me allay at once any apprehension you may have that I am about to recapitulate all that has been said during the past two days. Redundancy at this time would merely accentuate your current soporific state. Thus I shall take advantage of the prerogative of seniority to modify the title of my talk to "Comments and conclusions concerning studies on estrous control in domestic animals."

Evaluation Of Methods For Controlling The Estrous Cycle, William Hansel

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

Truly effective estrous cycle synchronization techniques are of great potential value to commercial producers of beef and dairy cattle, sheep, and swine. Many commercial beef cattlemen recognize the merits of using outstanding sires through artificial insemination (AI) to produce greater numbers of faster gaining cattle having the most desirable carcass characteristics. The relatively high heritability of feedlot gains makes this idea particularly attractive. Nevertheless, progress in attaining this goal has been rather slow, mainly because of the practical problems involved in breeding range cattle artificially and the low conception rates frequently obtained. Methods for cycle regulation compatible with the most …

Review Of Echinococcus Species In South Africa, Anna Johanna Maria Verster

Harold W. Manter Laboratory of Parasitology: Faculty Publications

1. The nominate subspecies of E. granulosus (Batsch, 1786) is redesignated from the type locality, Europe.

2. Five subspecies of E. granulosus are described from South African carnivores: E. g. granulosus, E. g. africanus, E. g. felidis, E. g. lycaontis and E. g. ortleppi.

3. E. g. granulosus has so far only been recovered from the Transvaal; E. g. ortleppi appears to be restricted to the Transvaal; E. g. africanus occurs in the Orange Free State and the Transvaal; E. g. lycaontis and E. g. felidis like their definitive hosts are restricted to the Transvaal.

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 …

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 …

Limnology Of Carbonate – Bicarbonate Lakes In Nebraska, D. B. Mccarraher

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The relation between chemical, physical and biological indices was examined in 1,640 sandhill lakes during the years of 1954 to 1963. Sandhill lakes are formed by either (1) wind deflation basins and closed drainages or (2) exposed ground water table basins. Topography of the 20,000 square mile sandhill region is primarily stabilized dune sand interspersed with wet meadows and pine - cedar - oak river drainage systems. Two-thirds of the area is dune sandhills and one-third occupied by basins, valleys and lakes.

All of the lakes are comparatively shallow, the deepest lake being Blue Lake with 13.8 feet. The average …

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.

These questions raise a larger, overarching question predictability:Would knowledge of ingenuity, visualization ability, and reasoning ability aid in predicting achievement in science and related fields in high school and college? …

The Specific Status Of The Narrow-Skulled Vole (Subgenus Stenocranius Kashchenko) In North America, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

On morphological and zoogeographical grounds, discussed in the present paper, it is concluded that the narrow-skulled vole in North America, previously designated Microtus (Stenocranius) miurus Osgood, is conspecific with the Eurasian M. (Stenocranius) gregalis Pallas. Fourteen subspecies in Eurasia and 5 in North America are now recognized, but it is probable that the number in Eurasia will be reduced through future investigation. The Eurasian subspecies of this vole comprise two major groups, of which one occupies the tundra zone and the other occurs across central Asia below latitude 60° N; their geographic ranges are largely separate …

Seasonal Population Fluctuations And Natural Control Of The Sweetclover Aphid, G. R. Manglitz, R. E. Hill

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Because the potential of the sweetclover aphid for damaging sweetclover is well documented, yet damage occurs only occasionally under field conditions, it would appear that natural factors which depress midsummer populations are important in preventing greater damage and worthy of detailed study. Thus, this study was begun early in 1959 to investigate the natural factors which generally keep populations of this aphid below levels causing economic damage.

Phytotoxic Substances From Soil Microorganisms And Crop Residues, T.M. Mccalla, F.A. Haskins

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

The role of organic matter in the growth of plants has been a subject of much investigation and controversy since the sixteenth century. During the early era, decomposition of plant residues and green and animal manures provided a primary source of minerals for plant growth. In addition, beneficial effects on soil structure and water-holding capacity were attribute to the presence of organic matter. With the development of agricultural chemistry culminating in the work of Liebig in the nineteenth century, it was discovered that plants could make satisfactory growth in the absence of added organic matter if suitable kinds and amounts …

Culture And O-Hydroxycinnamic Acid Content Of Excised Melilotus Roots, Larry G. Williams, Francis A. Haskins, Herman J. Gorz

Department of Agronomy and Horticulture: Faculty Publications

Excised roots of biennial sweetclover were successfully cultured through repeated transfers on a modified White's medium solidified with agar. Roots also grew well in shaker-agitated liquid cultures over the pH range 4.5 to 7.0. Exposure of the cultures to bright illumination resulted in submaximal growth. No net synthesis of o-hydroxycinnamic acid was observed in the cultured roots.

Arctic Health Research Center, U.S. Public Health Service, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A program of research in Alaska was initiated by the United States Public Health Service in 1948, with the establishment of a field station in temporary facilities located at Anchorage. This station, officially designated the Arctic Health Research Center in May 1950, was founded largely as the result of surveys of health conditions in Alaska conducted during 1946 and 1947 by two committees representing the American Medical Association. The reports of these committees led Congress to pass a special appropriation bill to support the investigation of health problems in Alaska.

Six research sections were set up within the first year. …

Closing Remarks: Second Vertebrate Pest Control Conference, Maynard W. Cummings

Vertebrate Pest Conference Proceedings: 2nd (1964)

The Second Vertebrate Pest Control Conference is concluded. We hope it has been, in some measure, educational and worthwhile to each one of you. Many of you who are here attended the first conference, which was held in Sacramento two years ago. The obvious spirit displayed at that meeting, a genuine intense interest in absorbing new knowledge presented by the speakers, the warmth of making and renewing acquaintances among fellow workers and the enjoyment of the truly rare opportunity to exchange information in this special field, vertebrate pest control, has, I feel, been reenacted here. For these reasons this second …

The Evolution Of Plague Control In California, Keith F. Murray

Vertebrate Pest Conference Proceedings: 2nd (1964)

Bubonic plague no longer is regarded as the dreaded black death of the middle ages. The last great plague pandemic has come to an end. In California, human cases have averaged no more than one every two years for several decades. With modern antibiotics properly administered, recovery is assured. At the same time, there is no doubt that plague is firmly entrenched in the rodent fauna and we should not be lulled even by years of quiescence into assuming that massive epizootics will not break out in the future. There is the un-measurable risk of a quick pneumonic outbreak with …

Highlights Of Bird Control Research In England, France, Holland, And Germany, John L. Seubert

Vertebrate Pest Conference Proceedings: 2nd (1964)

The purpose of this paper is to present a brief review of the research being conducted in England, France, Germany, and The Netherlands on problems caused by nuisance and depredating birds. Much of the information presented has been obtained through correspondence with collaborators. In the fall of 1962, I discussed depredating bird and bird-airport problems with research workers in these countries, and also attended the meeting of the International Union of Applied Ornithology held in Frankfurt/Main. In November 1963, I attended an international symposium about the bird-airport problem, held in Nice, France. This paper will draw attention to the current …

Pest Control Methods And People, John E. Swift

Vertebrate Pest Conference Proceedings: 2nd (1964)

Frankly I am not sure what "Pest Control Methods and People" really means. When I asked what I should cover, I was told to give a general discussion on pesticides. I am not sure this is appropriate even though the laws and regulations that pertain to other pesticides apply equally to those materials used in vertebrate pest control; the conditions of use, the types of chemicals used, their effect upon various animal species, and the number of chemicals available are so different from the pesticides used in controlling invertebrate pests that generalizations may not cover the topic. There are, however, …

Methods Of Controlling Blackbird Damage To Field Corn In South Dakota, John W. De Grazio

Vertebrate Pest Conference Proceedings: 2nd (1964)

One of the most widespread bird problems in the Western United States is damage to ripening cereal grain crops. Crops such as corn, rice, and sorghum, when grown close to favored roosting areas are often subject to serious damage from large flocks of feeding blackbirds. The redwinged blackbird is the most numerous species and causes most of the damage, but other blackbird species, including the yellow-headed blackbird, the common grackle, the brown-headed cowbird, and Brewer's blackbird, also contribute to damage problems. The Denver Wildlife Research Center is actively investigating methods to combat blackbird depredations to field corn in the vicinity …

Bats: Their Public Health Importance And Control With Special Reference To Trinidad, Arthur M. Greenhall

Vertebrate Pest Conference Proceedings: 2nd (1964)

This brief review of the public health importance and control of bats is oriented to Trinidad, where, during the past ten years I investigated their zoomedical importance (1). Trinidad is noted for Pawan's classic epidemiological studies of bat rabies (2,3) as well as its bat control program with which I have been associated since its inception in 1934 (4). Further, Trinidad has bat problems, in addition to rabies, which occur in other countries of the world. Although various methods of bat control have been developed in Trinidad, the field is virtually unexplored. Increasingly, bat control is a matter of paramount …
