Sizing Of Liquid Manure Tank Wagons And The Economic Evaluation Of Liquid Manure Injection, J.N. Scarborough, Elbert C. Dickey, D. H. Vanderholm

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Liquid manure tank wagons were evaluated on a cost basis to determine the optimum size for a given livestock operation. Also the economics of adding a liquid injector to the tank wagon was studied for profitability.

INTRODUCTION

The proper selection of a liquid manure tank wagon is a problem faced by many progressive livestock producers with liquid manure systems. Selection of a manure tank wagon is usually based on the farmer's or dealer's opinion of what size is right rather than on a logical analysis including an economic analysis of the costs involved. This paper provides guidelines for selecting the …

Adult Cestodes From The Coelomic Cavity Of The Teid Lizard, Cnemidophorus Sexlineatus, Wesley L. Shoop, John J. Janovy Jr.

John J. Janovy, Jr. Publications

In a survey of 64 Cnemidophorus sexlineatus, adult cestodes identified as Oochoristica bivitellobata with gravid proglottids were found in the coelomic cavity of two hand caught specimens at Cedar Point Biological Station, Ogallala, Nebraska, during June and July 1977. Two O. bivitellobata were found free in the coelom of a male lizard, whereas four were found in the coelom and one in the intestine of a female. No ruptures were found in the walls of the intestines of all lizards examined. In addition, 61 O. bivitellobata were found in the intestine of nine (14%) of the C. sexlineatus with …

Distribution Of Two Species Of Long-Eared Bats Of The Genus Myotis On The Northern Great Plains, J. Knox Jones Jr., Jerry R. Choate

University of Nebraska State Museum: Mammalogy Papers

Two long-eared species of the cosmopolitan bat genus Myotis, the long-eared myotis (Myotis evotis) and the fringe-tailed myotis (Myotis thysanodes), have been known for many years from the Northern Great Plains. Material acquired in the last decade or so, however, reveals a somewhat different distributional pattern for the two species than had been supposed on the basis of specimens obtained earlier, some of which have been misidentified in the published literature.

Calculated Yields And Slowing-Down Spectra For Electrons In Liquid Water: Implications For Electron And Photon Rbe, R. N. Hamm, H. A. Wright, Robert Katz, J. E. Turner, R. H. Ritchie

Robert Katz Publications

Detailed Monte Carlo calculations have been carried out of slowing-down spectra and yields for a number of end-points for electrons in liquid water. These investigations were made to study differences in physical effects of different low-LET radiations and implications for RBE. Initial electron energies from 1 keV to 1 MeV were used, and all secondary electrons were followed in the computations until their energies fell below 10 eV. Though there are substantial differences in the slowing-down spectra at energies near and above the K-shell ionization potential of oxygen, the energy spectrum of electrons at lower energies is found to be …

Bats Of Guadeloupe, Robert J. Baker, Hugh H. Genoways, John C. Patton

University of Nebraska State Museum: Mammalogy Papers

The bat fauna of the Lesser Antillean chain is of considerable interest because it is composed of a depauperate extension of the South American fauna, species that have a widespread distribution in the Antilles, and a few species that are endemic to the Lesser Antilles (Baker and Genoways, 1978). Relative to bat speciation and diversity, Guadeloupe is probably the most important island of the Antillean chain.

This report is concerned with the natural history and systematics of the 11 chiropteran species known from Guadeloupe, three of which are endemic. Comments concerning systematic relationships are based on specimens that we collected …

Residues Of Carbofuran Applied As A Systemic Insecticide In Irrigated Wetland Rice: Implications For Insect Control, J. N. Seiber, Elvis A. Heinrichs, G. B. Aquino, S. L. Valencia, P. Andrade, A. M. Argente

Department of Entomology: Faculty Publications

The behavior of carbofuran residues in rice plants treated by broadcast, soil incorporation, and root-zone application,and by seedling root-soak and root-coat technique was studied. Placement of insecticide in gelatin capsules in the root zone gave good persistence (about 60 days) and leaf residue (as much as 45 ppm at 10 days after treatment). Among the methods tested it also controlled early season pests best and gave the highest grain yields. Soil incorporation and root-zone placement with a liquid-band applicator was also more efficient than paddy-water broadcast in getting insecticide to the plant; soil incorporation provided slightly longer persistence (60 days) …

Microhabitat Selection In Two Species Of Heteromyid Rodents, Cliff A. Lemen, Michael L. Rosenzweig

School of Natural Resources: Faculty Publications

An experiment was conducted to determine the microhabitat preferences of two heteromyid rodents, Dipodomys ordi and Perognathus flavus. This experiment used marked seeds and the atomic absorption spectrophotometer in order to study the environment as a mosaic of microhabitats. The results of our analysis indicate that these two heteromyids are microhabitat selectors. The preferences of the rodents are, D. ordi: grass habitat 0.0%, near grass habitat 22.5%, open habitat 77.4%, and P. flavus: grass habitat 46.2%, near grass habitat 32.2%, open habitat 21.4%. The overlap between the two species is only 0.43.

Spirocamallanus Cricotus Sp. N. And S. Halitrophus Sp. N. (Nematoda: Camallanidea) From Fishes In The Northern Gulf Of Mexico, Alan C. Fusco, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Spirocamallanus cricotus sp. n. (= S. pereirai, in part) and S. halitrophus sp. n. are described from marine fishes of the northern Gull of Mexico. Spirocamallanus cricotus has a ledge anterior to the basal ring in the buccal capsule, similar spicules with a ratio of 1:1.4 to 2.1, 3 pre- and 5 postcloacal papillae, and 8 rectal glands in the female; S. halitrophus lacks the ledge and possesses dissimilar spicules with a ratio of 1:1.3 to 1.8, 3 pre- and 6 postcloacal papillae, and 4 rectal glands in the female.

The Opossum (Didelphis Virginiana) As A Host For Sarcocystis Debonei From Cowbirds (Molothrus Ater) And Grackles (Cassidix Mexicanus, Quiscalus Quiscula), Donald Duszynski, Edith D. Box

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Sarcocystis-infected muscles from ducks, cowbirds, and grackles were fed to cats, opossums, rats, and a dog. Only the opossum (Didelphis virginiana) was a suitable definitive host. All opossums that were fed Sarcocystis-infected cowbirds (Molothrus ater) and grackles (Cassidix mexicanus and Quiscalus quiscula) passed sporocysts in their feces. Opossums that ate the cowbirds had prepatent periods of 5 and 10 days and remained patent for at least 105 days. Opossums that ate the grackles became patent on day 10 after the infective meal and remained patent for over 90 (Quiscalus) and …

Bats From Southern Haiti, David Klingener, Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

A collection of 450 specimens of bats from the Departement du Sud, Haiti, is described. Fifteen of the 17 species previously recorded from Hispaniola are represented, and Noctilio leporinus is reported from Haiti for the first time. Reproductive information for the months of January, May, June, August, and December is presented. Macrotus waterhousii is seasonally monoestrous, as on the mainland. The two species of stenodennines, Artibeus jamaicensis and Phyllops hailiensis, do not show bimodal seasonal polyestry as do stenodermines in Central America. Monophyllus redmani and the phyllonycterines may be seasonally monoestrous. Differences in reproductive biology between Haitian bats and …

Reclassification Of The Gray Wolf In The United States And Mexico, With Determination Of Critical Habitat In Michigan And Minnesota

Rocky Mountain Wolf Recovery: Annual Reports

The Service issues a final rulemaking which provides for the reclassification of the gray wolf in the United States and Mexico, and for the determination of critical habitat for species of gray wolf in Michigan and Minnesota. The reclassification is considered to accurately express the current status of the gray wolf, based solely on an evaluation of the best available biological data. The special regulations being established in Minnesota are deemed necessary and advisable to provide for the future well-being of the species. Although an increased legal take of wolves committing depredations on domestic animals will be authorized, this take …

Some Problems Concerning The Control Of Bird Damage In Southwestern Nigeria , M. Akande

Vertebrate Pest Conference Proceedings: 8th (1978)

The problems of controlling bird damage, especially to crops, may be both social and practical. The practical problems are subject to environmental and ecological factors. The social problems relate to lack of adequate biological knowledge of the pest species, lack of confidence between farmers and researchers, persistent government red tapes, and human feelings. Damage is often as a result of feeding and nesting activities. Control measures include both prevention of contact between birds and crops by erection of barriers, use of chemical repellents and scaring devices, and attempted reduction in numbers of pest species, by shooting and trapping. None of …

Control Of The House Mouse (Mus Musculus L.) In The Netherlands, B.T. Bosman

Vertebrate Pest Conference Proceedings: 8th (1978)

Rodent control is carried out by local authorities, extermination companies or the owners of infested premises. The control of the house mouse, especially in food-handling establishments, is a problem that has existed for some years. Testing in the laboratory indicates a warfarin resistance although the application of new rodenticides like bromadiolone, calciferol and difenacoum has given good results. A "manual" for the control of suspected warfarin resistant house mice is given.

Establishing Native Forbs To Reduce Black-Tailed Deer Browsing Damage To Douglas-Fir, Dan L. Campbell, James Evans

Vertebrate Pest Conference Proceedings: 8th (1978)

Principal methods being used to alleviate browsing damage to Douglas-fir (Pseudotsuga menziesii) seedlings by black-tailed deer (Odocoileus hemionus columbianus) in the Pacific Northwest are animal repellents applied to foliage and plastic mesh cylinders around individual seedlings. As an alternate method, we demonstrated that prompt establishment of highly palatable native forbs reduced summer browsing on planted seedlings to the point that black-tailed deer were no longer a factor limiting Douglas-fir regeneration. We believe that establishing native forbs is a sound ecological approach to deer-reforestation problems; furthermore, it should have wide utility because it integrates forest- and wildlife-management …

Control Of Ground Squirrels In California Using Anticoagulant Treated Baits, Dell O. Clark

Vertebrate Pest Conference Proceedings: 8th (1978)

Anticoagulant treated grain baits have been used to control vertebrate pest depredations in California for over 30 years. The use of anticoagulant treated baits has increased seven (7) times in the past seven (7) years; the majority for the use of ground squirrel, Spermophilus spp., control. Since 1968-69, an average of 1,747,828 net over 5,700,919 gross acres per year has been treated for ground squirrel control.

Current use patterns for ground squirrel control with anticoagulant treated baits include: (1) Repeated spot baitings, and (2) exposure of bait in bait boxes.

Experimental work and many years of operational field use have …

A Public Information Program On Predator Damage Control, David S. Decalesta

Vertebrate Pest Conference Proceedings: 8th (1978)

A public information and education program was developed in Oregon to defuse a controversy between environmentalists and livestock growers over management of predator damage control. Emphasis was placed on involving special interest and leadership/influential groups in the program and participa-tion was high. Attempts were made to involve the "general public" but response to solicitation and participation were low. Participating groups thought the program was of high value and expressed the need for additional information. Attitudes and beliefs of the special interest groups were changed little by the program, but constructive communications between the groups increased and the controversy dwindled. A …

Brodifacoum (Talon™ Rodenticide), A Novel Concept, A.C. Dubock, D.E. Kaukeinen

Vertebrate Pest Conference Proceedings: 8th (1978)

Brodifacoum, a new rodenticide, is described. This anticoagulant is shown to be of exceptional potency and capable of controlling resistant rodents as well as several non-commensal species. Results demonstrate that, in contrast to first generation anticoagulants, a bait concentration of only 50 ppm is adequate to give control and in only a single feeding for most species. In common with other anticoagulants, vitamin K₁ is an effective antidote. In contrast with other acute rodenticides, symptoms are delayed and no bait shyness is observed. The results of laboratory and field trials from many parts of the world are summarized and …

Electromagnetic Repellers—Fact Or Fiction?, William D. Fitzwater

Vertebrate Pest Conference Proceedings: 8th (1978)

The effectiveness of devices that supposedly repel a large number of invertebrate and vertebrate animals by emitting oscillating electromagnetic impulses is investigated. While scientific support that electromagnetic forces affect biological systems exists, these data are based on animals confined under higher intensity fields than are seemingly produced by commercial units. A number of instances of field use of the devices is discussed. These indicate little objective support for the units.

Management Of Blackbird And Starling Winter Roost Problems In Kentucky And Tennessee, Kenneth M. Garner

Vertebrate Pest Conference Proceedings: 8th (1978)

Blackbirds and starlings in winter roosts create conflict problems in five major categories: 1) Public Health, 2) Agricultural Crop, 3) Wildlife Competition, 4) Structural, 5) Safety. After identification of problems created by an individual roost and roost site, problems are solved by one or a combination of seven methods: 1) No Action, 2) Move the Roost, 3) Alteration of Agricultural Practices, 4) Bird Proofing, 5) Move Birds from Feeding or Loafing Site, 6) Population Reduction at Feedlots, 7) Population Reduction of Roosts.
