Effects Of Genetic Type And Protein Levels On Growth Of Swine, O.W. Robison, L. L. Christian, R. Goodwin, R. K. Johnson, J. W. Mabry, R. K. Miller, M. D. Tokach

Department of Animal Science: Faculty Publications

A total of 1,588 pigs representing six genetic lines were included in this study. These lines were selected to represent a wide range of biological types for appetite, rate and composition of gain, and meat quality traits. Each line was fed four different diets differing in lysine content. Barrows and gilts were used in the experiment, and pigs were randomly assigned to come off test at one of three weights (113.6, 131.8, or 150 kg). Rates of increase in weight, backfat thickness, and longissimus muscle area were essentially linear. Genetic type and diet influenced (P < .05) rates of change in weight, backfat thickness, and longissimus muscle area and 10th rib fat depth, carcass longissimus muscle area, and dressing percentage. Genetic type × diet interactions were significant for weight change and 10th rib fat. As off-test-weight class increased fat and longissimus muscle area increased in linear fashion. In general, interactions associated with diet resulted from feeding the diet lowest in lysine. There was little evidence of genetic type × diet interactions. If those interactions that tested significant are real, they are a result of extremes in both genetic type (high fatness) and lysine level (low). Slaughtering pigs at heavier weights results in no change in rate of gain over the feeding period and linear increases in longissimus muscle area and backfat thickness.

Strategy For The Conservation Of Non-Game Birds In The State Of Nebraska, Jacqueline Lee Canterbury

Department of Animal Science: Dissertations, Theses, and Student Research

Non-game birds comprise 93% of the 831 species recorded in the U.S; of these, forest birds and neotropical migrants have received considerable attention. To develop a management plan for non-game birds in Nebraska, historically a predominately grassland ecosystem, it was necessary to determine species in need of conservation and assess their respective habitat status. Using BBS and PIF databases, we developed a prioritization scheme that identified 44 breeding species in need of conservation in Nebraska; 20 of the 44 are grassland birds. Because several species in need of conservation known to occur in the state were missing from these databases, …

Burrow Morphology And Behavior Of The Mud Shrimp Upogebia Omissa (Decapoda: Thalassinidea: Upogebiidae), Vania Rodrigues Coelho, Roland Arthur Cooper, Sergio De Almeida Rodrigues

Collected Faculty Scholarship

The burrow morphology, burrowing behavior and feeding mechanisms of the thalassinidean shrimp Upogebia omissa were studied. Twenty burrow casts were made in situ with epoxy resin, and an overall 'Y' shape was most frequently observed. Several burrows consisted of a single, oblique tunnel; burrow diameter was positively correlated with burrow length, maximum depth and distance between openings. Additionally, burrow length was positively associated with maximum depth, indicating that as burrow length increased burrow depth increased; i.e. burrows spread vertically rather than horizontally. Total sediment displacement by the burrows accounted for 2.6 % of sediment to a depth of 30 cm. …

Swine Nutrition Guide, Duane E. Reese, Robert C. Thaler, Michael C. Brumm, Austin J. Lewis, Phillip S. Miller, George W. Libal

Department of Animal Science: Faculty Publications

This publication is a revision of the previous swine nutrition publication prepared by the University of Nebraska and South Dakota State University. The focus of the publication continues to be on nutrient recommendations for swine. Specific factors (nutritional, environmental and managerial) that affect nutrient recommendations (Figure 1) have been considered and discussed. We believe that the identification and description of the factors in Figure 1 provide the framework for the nutrient recommendations presented in Tables 11 to 16. Industry advisors representing various facets of the pork industry were recruited to review and challenge the concepts incorporated in this publication. Also, …

Comparative Systematics Of Subterranean Amphipod Crustaceans In The Families Crangonyctidae And Bogidiellidae, Stefan Koenemann

Biological Sciences Theses & Dissertations

The research project presented in this doctoral dissertation deals with the systematics of two different taxonomic groups of subterranean amphipods (Crustacea). Therefore, rather than being a single project, this study is divided into several sub-projects. Altogether, the chapters for the sub-projects are composed of five publications. An introductory chapter and a summarizing discussion are added to provide a structural unit for the collection of papers and to compare the results of the individual projects.

The thesis investigates the systematics of the amphipod families Bogidiellidae Hertzog, 1936, and Crangonyctidae Bousfield, 1973. Based on descriptive taxonomy according to modern standards, revisions are …

An Ultrastructural Survey Of The Nuchal Glands Of Rhabdophis Tigrinus (Serpentes: Colubridae), Kathleen A. Roberts

Biological Sciences Theses & Dissertations

Rhabdophis tigrinus, an Asian natricine snake, possesses a series of integumentary glands located in the nuchal skin. Previous studies indicated that the nuchal glands are of mesodermal origin, contain cardiac steroids analogous to bufotoxins found in the parotoid glands of toads, which are included in the snake's diet. The nuchal glands are defensive in function. Preliminary histological studies revealed differences in quality of the gland tissue compared to previous studies, and difference in fixation techniques were suspected. Seven specimens of R. tigrinus were fixed by perfusion using a conservative fixation process standard for electron microscopy. The nuchal gland series …

The Effects Of Silviculture And Prescribed Burning On Herpetofauna In Florida Sand-Pine Scrub, Stig Ravdal

USF Tampa Graduate Theses and Dissertations

Florida sand pine scrub is among the most endangered habitats in the United States and much of the remaining scrub is heavily influenced by management for timber production. In this study the effects of timber management practices on herpetofaunal community diversity and composition were investigated on experimentally manipulated plots near Orlando, Florida. Plots at three sites were either harvested, burned, or treated as a control (unmanipulated). Herpetofauna were trapped using pit-fall drift-fence trapping arrays. Animals were counted, measured, marked and released from March 1996 to June 1998. During this time period 1489 reptiles and amphibians were caught from 31 different …

A Quality Future For Recreational Fishing On The West Coast., West Coast Recreational Fishing Working Group

Fisheries Management Papers

The West Coast Region between Kalbarri and Augusta offers a wide range of recreational fishing opportunities.The West Coast Region also receives more fishing pressure than any other, with an estimated 380 000 anglers fishing each year. Already, the signs of a fishery under pressure are showing. Catch rates of dhufish around inshore reef systems such as the Three-mile are a far cry from the 1950s and 60s when people beachlaunched wooden dinghies to fish the inshore waters for these highly prized fish. Increasing pressure on stocks has led to growing community concerns that the future quality of recreational fishing is …

Aquaculture Plan For The Recherche Archipelago, Fisheries Western Australia.

Fisheries Management Papers

Land supply and land cost for aquaculture may become a limiting factor in the foreseeable future. At present, adequate appropriately zoned land is available at reasonable cost. The most prospective land for aquaculture in or near Esperance is where suitable zoned land occurs over saline ground water aquifers or adjacent to the coast. Careful site selection would be necessary to ensure water supply, waste water disposal, services and operational space can be achieved at reasonable cost.

Fisheries Research Report No. 122 - Western Rock Lobster Mail Surveys Of Licensed Recreational Fishers 1986/87 To 1998/99, Roy Melville-Smith, Sonia M. Anderton

Fisheries Research Reports

Information on the catch, effort and fishing characteristics of recreational rock lobster fishers has been collected in Western Australia (WA) since 1986, by an annual mail survey of a randomly selected sample of rock lobster licence holders. Over the period 1986-1999, the number of licensed recreational rock lobster fishers in WA has approximately doubled, from 15,249 (1987/88) to 32,768 (1998/99), and the estimated catch has nearly tripled, from 219 tonnes (1987/88) to 626 tonnes (1998/99). These estimates have not attempted to take into account illegal catches.

Of those who do fish, approximately 65% of recreational rock lobster licence holders exclusively …

Macroevolution In Microchiroptera: Recoupling Morphology And Ecology With Phylogeny, Patricia W. Freeman

University of Nebraska State Museum: Mammalogy Papers

No family of mammals has undergone a greater adaptive radiation than phyllostomid bats. Phylogeny combined with eco-morphological considerations of trophic structures can help understand this adaptive radiation and the evolution of Microchiroptera. Microchiropteran bats are overwhelmingly insectivorous, and constraints within the morphospace of insectivory have produced a dynamic equilibrium in bat morphologies that has persisted for 60 million years. The ability to eat fruit may be the key synapomorphy that allowed phyllostomids to escape insectivore morphospace and diversify. Although many phyllostomids have changed greatly, others that have maintained insectivory have changed little, which is equally remarkable.

South Dakota Fisheries: An Evaluation Of A Chemical Immersion Marking Technique For Juvenile Yellow Perch And Application To A Stocking Assessment Of Marsh-Reared Yellow Perch Into Eastern South Dakota Lakes, Michael L. Brown, Todd St. Sauver, David O. Lucchesi, Jennifer L. Glib, M. Elizabeth Reinhart

Natural Resource Management Faculty Publications

Currently, yellow perch Perca flavescens stocking needs in South Dakota are met by intensive trap and transfer of juvenile and adult perch. The success of these stocking efforts is largely undocumented, primarily due to problems in distinguishing yellow perch produced within the recipient water body and stocked perch. We first developed a transfer-tank marking protocol to determine immersion duration and optimal concentration of oxytetracycline (OTC) hydrochloride needed to produce an effective mark. Then we validated the protocol for adult yellow perch and determined the persistence of OTC in edible muscle tissue. Marking results indicated that satisfactory OTC marks may be …

A Century Of Breeding Birds In Nebraska, Jackie Canterbury, Paul A. Johnsgard

Papers in Ornithology

With the imminent publication of the Nebraska Breeding Bird Atlas and the turning of a new millennium, it is perhaps an appropriate time to survey the state of breeding birds in Nebraska. Wayne Mollhoff’s summary of the N.O.U.’s Nebraska Breeding Birds Aliasing Project (Mollhoff, 2000) provides important databases for the latter part of the past century, and the historic overview by James Ducey (1988) offers a useful basis for judging the breeding avifauna of Nebraska from about the beginning of the century. The Biological Resources Division of the U. S. Geological Survey’s (WSGS-BRD) annual Breeding Bird Survey data currently extends …

Comparison Of Plasma Fsh Concentration In Boars And Gilts From Lines Selected For Ovulation Rate And Embryonal Survival, And Litter Size And Estimation Of (Co)Variance Components For Fsh And Ovulation Rate, R. K. Johnson, J. J. Ford

Department of Animal Science: Faculty Publications

The objective of this research was to determine whether plasma concentration of FSH was genetically correlated with ovulation rate and thus was a useful trait for indirect selection. Blood samples were collected from 619 animals from five lines of pigs. Line I was selected for increased index of ovulation rate and embryonal survival, and Line C was its randomly selected control. Pigs sampled from Lines I and C were from generations 12 and 13. Pigs from three additional lines that were derived from eighth-generation pigs of Lines I and C also were used. These lines were Line C2, a randomly …

Extralimital Records Of The Mexican Free-Tailed Bat (Tadarida Brasilensis Mexicana) In The Central United States And Their Biological Significance, Hugh H. Genoways, Patricia W. Freeman, Cary Grell

School of Natural Resources: Faculty Publications

Two new records of Tadarida brasiliensis mexicana are reported from Nebraska. The literature records of this taxon from the central United States are summarized. In this region of North America, these bats occupy a “natal range” where the species carries on regular reproductive activities and the populations are relatively stable, including California, Arizona, New Mexico, Texas, and Oklahoma. To the north of the natal range of T. b. mexicana is a “pioneering zone” where, under favorable conditions, the species is capable of reproducing and conducting its normal activities. The pioneering zone of the Mexican free-tailed bat includes Barber and Comanche …

Shifting Distributional Patterns Of Mammals In Nebraska, Russell A. Benedict, Hugh H. Genoways, Patricia W. Freeman

School of Natural Resources: Faculty Publications

New distributional records are presented for 20 species of mammals in Nebraska. The majority of these records appear to represent changes in geographic distribution rather than just better sampling in poorly known areas. One group of mammals, including the opossum, northern myotis, evening bat, red bat, woodchuck, white-footed mouse, and gray fox, is expanding westward, probably in response to increasing woodlands along river systems. Another group, including the meadow vole, masked shrew, and least weasel, is expanding southward, possibly in response to new prey species and changing microclimates. The eastern woodrat appears to be expanding northward in eastern Nebraska. The …

Fisheries Research Report No. 119 - Final Report, Frdc Project 95/037: The Biology And Stock Assessment Of The Tropical Sardine, Sardinella Lemuru, Off The Mid-West Coast Of Western Australia, Daniel J. Gaughan, Ronald W. Mitchell

Fisheries Research Reports

Exploratory fishing for the tropical sardine, Sardinella lemuru, offshore of Geraldton on the midwest coast of Western Australia in the early 1990s, led to the establishment of a developmental purse seine fishery in this region. This fishery showed potential for substantial expansion, but as there was no information on S. lemuru in WA there was a need to undertake research during the developmental period. The biology and fishery for S. lemuru in WA were therefore investigated over a three year period between July 1995 and June 1998 with the aim of providing stock assessment advice.

The biology of S. lemuru …

Fisheries Research Report No. 121 - Synopsis Of The Biology And Exploitation Of The Blue Swimmer Crab, Portunus Pelagicus Linnaeus, In Western Australia, Mervi I. Kangas

Fisheries Research Reports

This report summarises the existing studies which have provided information on the biology, population characteristics and exploitation of the blue swimmer crab, Portunus pelagicus, in Western Australia. Gaps in the existing knowledge are also highlighted to assist in targeting new research initiatives. Portunus pelagicus matures at about one year and in temperate regions females mate only once a year. This is because mature crabs moult only once a year. It appears from studies to date that Western Australian crabs are one genetic population. This is being further investigated. Migration of the blue swimmer crab occurs between estuaries and the ocean …
