Parasitangrepp I Ögon Hos Fisk, Som Lever I Kylvatten Från Kärnkraftsreaktorer, Johan Höglund, Jan Thulin

Harold W. Manter Laboratory of Parasitology: Library Materials

Sammanfattning

Under åren 1983 t.o.m. 1987 undersöktes förekomst, intensitet och skadeverkan av ögonsugmaskar hos fisk, som påverkats av en förhöjd vattentemperatur. Undersökningarna utfördes huvudsakligen i Biotestsjön, som är ett 1 km² stort invallat havsområde (S ^o/_oo salthalt), som mottager uppvärmt (ca. 8 °C) kylvatten (ca. 90 m³ / s) från Forsmarks kärnkraftverk. Både de morfologiska och experimentella undersökningarna med metacerkarier tyder på att det förekommer fyra olika arter av släktet Diplostomum i Biotestsjön, två i abborre och två i mört. Då taxonomiska revisioner pågår utomlands föredrogs att kalla dessa arter Diplostomum sp1-4. Metacerkarier av D. …

Estimates Of Genetic And Environmental (Co)Variances For First Lactation Milk Yield, Survival, And Calving Interval, M. C. Dong, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Variance and covariance components for milk yield, survival to second freshening, and calving interval in first lactation were estimated by REML with the expectation and maximization algorithm for an animal model which included herd-year- season effects. Cows without calving interval but with milk yield were included. Each of the four data sets of 15 herds included about 3000 Holstein cows. Relationships across herds were ignored to enable inversion of the coefficient matrix of mixed model equations. Quadratics and their expectations were accumulated herd by herd. Heritability of milk yield (.32) agrees with reports by same methods. Heritabilities of survival (.11) …

Heritabilities Of And Genetic Correlations Among Six Health Problems In Holstein Cows, H. K. Lin, P. A. Oltenacu, L. Dale Van Vleck, H. N. Erb, R. D. Smith

Department of Animal Science: Faculty Publications

Information from 7712 lactations of Holstein dairy cows was collected from 33 commercial herds around Ithaca, NY in the 3 yr from 1981 to 1983. The data were divided into subsets corresponding to lactation 1, lactation 2, and lactation 3 or greater. To estimate heritabilities of dystocia, retained placenta, metritis, ovarian cysts, milk fever, and mastitis, a mixed linear model (herd-year fixed and sire random effects) with 0 or 1 as the observed response was used. Variance components were estimated using Henderson's Method 3. The results show moderate heritabilities (.15 to .40) for dystocia, metritis, milk fever, and mastiffs and …

On The Status Of Eimeria Nieschulzi Oocysts Embedded In Resin Eleven Years Ago: A Permanent Method For Preserving Coccidian Oocysts, Alan A. Marchiondo, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Sporulated oocysts of Eimeria nieschulzi that were fixed and mounted on glass slides in polymerized resin in 1976 are examined. Size, shape, and integrity of oocysts and sporocysts are compared to similar observations we made in 1977 and reported in 1978 (Journal of Parasitology 64: 163-164). Our conclusion is that the methods we reported on in 1978 provide one opportunity to produce permanent specimens of sporulated oocysts that could be made available for deposit in nationally accredited museums.

A Plea For Improved Presentation Of Type Material For Coccidia, Susan M. Bandioni, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The "true" coccidia (phylum Apicomplexa, suborder Eimeriina) constitute a large and heterogeneous group of parasitic protozoa. Despite the large number of described species (ca. 1,650) and the medical and veterinary importance of some (e.g., Toxoplasma), 2 facts are clear: (1) the majority of coccidia species are probably yet undescribed, and (2) the phylogenetic relationships of those described species are poorly known. Contributing to the latter dilemma is the lack of a tradition to provide type specimens by those who describe new species, even though the International Code of Zoological Nomenclature specifically recommends the designation of a type …

Predicting Milk Yield Of Holstein Cows From 306 To 395 Days In Milk, T. L. Stanton, R. W. Blake, M. A. Tomaszewski, P. F. Dahm, L. Dale Van Vleck, K. E. Olson, R. E. Goodwill, K. R. Butcher

Department of Animal Science: Faculty Publications

Prediction equations were determined to estimate daily milk yield from 306 to 395 d in milk for forecasting herd milk sales from Holstein cows in lactation > 305 d. Data were test day milk weights for 65,322 primiparous and 119,220 pluriparous lactations of > 305 d from the Southern US. A forecast model was developed using same lactation 305 d milk yield (in classes of 500 kg increments) that gave similar predicted daily yields as models utilizing last sample milk weight information. This model has the advantage of early forecasting of later milk using projected 305-d yields. Reduced forecast models ignoring days …

Potential Of Cytoplasmic Effects For Selection In Dairy Cattle, K. O'Neill, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Maternal cytoplasmic inheritance may cause an upward bias in heritability estimates from daughter on dam regression. Inaccurate evaluations of bulls or dams of future sires would result if such estimates were used in genetic evaluation. Expected genetic selection differential for bulls would be overestimated, but genetic gain would be little affected by incorrect heritability estimates. Genetic evaluations of dams of sires would be less accurate when incorrect heritability estimates are used, but actual selection differentials would be only slightly less than optimum. If cytoplasmic effects were ignored during selection, less genetic improvement would seem to be the result. However, expected …

Effect Of Relationships On Estimation Of Variance Components With An Animal Model And Restricted Maximum Likelihood, M. C. Dong, L. Dale Van Vleck, G. R. Wiggans

Department of Animal Science: Faculty Publications

Milk, fat, and protein yields in first lactation of two samples of 12 herds consisting of 4020 and 4024 Holstein cows in New York were used to estimate genetic and phenotypic covariances with an animal model by REML. Relationships were calculated within herd in three ways to provide inverses of relationship matrices. Full relationships consisted of tracing relationships to parents (base animals) of animals with milk and fat records between 1970 and 1980. Full relationships less base animals consisted of tracing relationships only one generation back from when protein records became available in 1981. Sire-only relationships were compiled using only …

Focality And Mobility Of Some Peridomestic Cockroaches In Florida (Dictyoptera: Blattaria), Richard J. Brenner

Entomology Papers from Other Sources

The microhabitat distribution and activities of peridomestic cockroaches were examined (August to October 1985) at three sites in northcentral Florida to assess concentration, immobility, and accessibility of populations. Smokybrown cockroaches, Periplaneta fuliginosa (Serville), and Eurycotis floridana (Walker) accounted for at least 67% of cumulative recaptures at each site. Populations were strongly concentrated in palms, trees with treeholes, woodpiles, and (to a lesser extent) various mulches; salient differences were observed for each species, indicating a partitioning of resources. Recapture rates were high, averaging >62% over all three sites for females of both species; rates were significantly lower for males (P < 0.05), but still averaged >40%. …

Common Goldeneye: Notes On Nebraska Fauna, Paul A. Johnsgard

Papers in Ornithology

0NE OF THE rewards for braving the remnants of a Nebraska winter by venturing out to newly thawed reservoirs, lakes and sandpits is the prospect of seeing a flock of common goldeneyes. Hard on the heels of winter, goldeneyes begin moving out of their wintering areas in the central and southern Great Plains and testing the waters to the north as as they become partially ice-free. Fair numbers of birds, sometimes in the thousands, often winter in western Nebraska, especially along the North and South Platte rivers, and in adjoining areas of eastern Wyoming and Colorado, but very few winter …

Genetic (Co)Variances For Milk And Fat Yield In California, New York, And Wisconsin For An Animal Model By Restricted Maximum Likelihood, L. Dale Van Vleck, M. C. Dong, G. R. Wiggans

Department of Animal Science: Faculty Publications

Two samples of data from approximately 4000 Holstein cows were analyzed by REML with a multivariate (milk and fat yields) animal model for first lactations started in 1970 through 1977 and in 1978 through 1985 and also for first lactation records started in low, middle, and high production herds in 1978 through 1985 separately for California, New York, and Wisconsin herds. Heritability estimates for milk yield (similar for fat yield) ignoring category of herd production were .29 for 1978 and later and .34 for 1977 and earlier. Estimates for low, middle, and high production herds were .23, .29, and .36. …

Genetic (Co)Variances For Milk, Fat, And Protein Yield In Holsteins Using An Animal Model, L. Dale Van Vleck, M. C. Dong

Department of Animal Science: Faculty Publications

First lactation milk, fat, and protein yields for first lactations of 8044 Holstein cows in New York from 24 herds were used to estimate genetic and phenotypic covariances with an animal model by restricted maximum likelihood. Numerator relationships within herd, including those from sires, were utilized, although relationships across herds were ignored. Each analysis was terminated after 300 rounds of iteration. Average milk production (twice daily milking, 305-d lactation, mature equivalent) was 8630 kg. Estimates were obtained for each individual herd and groups of 3, 6, and 12 herds. Average estimates from separate analyses of the 24 herds were nearly …

A Second Bald Eagle Nest In Nebraska, Greg Wingfield

Nebraska Bird Review

The Bald Eagle (Haliaeetus leucocephalus) in Nebraska is considered an uncommon migrant and locally common winter resident. Formerly, the species was a common breeder in eastern Nebraska (Johnsgard, 1986). The only previously known modern (1900s) nesting attempt took place in 1973 in Cedar Co., northeast of Crofton, Nebraska (Lock and Shuckman, 1973). This nest occurred along the Missouri River, downstream of Lewis and Clark Reservoir. Between the latter part of January and 25 March 1973, a pair of Eagles was observed while building a nest, copulating, perching near the nest, and sitting on the completed nest. Eventually, the …

Nebraska Bird Review

YOUNG GREAT HORNED OWLS On 5 April 1988 we banded two young Great Horned Owls that were in a nest near Laurel, in Cedar Co., Neb. An adult Owl was first seen on this nest 3 March. The nest was approximately 31 feet above the ground in a dead Siberian elm tree. One adult Owl was in the nest as we approached it at about 7:00 PM. The adult bird flew of the nest and remained about 200 meters away, in a small grove of trees. It took us about 35 minutes to set up our ladder, retrieve and band …

Occurrence Of Ross Geese (Chen Rossii) Detected From Avian Cholera Losses, Randy G. Stutheit

Nebraska Bird Review

During the annual spring waterfowl migration, an estimated 5-7 million ducks and geese pass through the Nebraska Rainwater Basins area. The Rainwater Basins area covers all or parts of 17 counties in south-central Nebraska, encompassing some 4,200 square miles. Wetlands of various size, depth, and water permanency are scattered throughout this area. These wetlands are important resting and feeding areas for ducks and geese on their migration north to the breeding grounds. Avian cholera, a highly infectious bacterial disease of waterfowl, has also been an annual visitor to the Rainwater Basins since 1975, killing from as many as an estimated …

Two Species Of Marsh Wren (Cistothorus Palustris) In Nebraska, Donald E. Kroodsma

Nebraska Bird Review

The consequences of a grand evolutionary experiment are evident throughout Nebraska. During the Pleistocene, many taxa were apparently separated into eastern and western populations. Today many of these eastern and western counterparts meet in the Great Plains, especially in Nebraska. Some pairs now hybridize freely (towhees. orioles. flickers), while others do not (buntings, grosbeaks, meadowlarks) (see Rising 1983).

The Marsh Wren is still another, previously unrecognized, taxon that consists of an eastern and western counterpart. Data from Nebraska and elsewhere in North America suggest that there are two forms of the Marsh Wren, perhaps as vocally different from each other …

Tundra Swans In Lincoln County, Nebraska, Greg Windfield

Nebraska Bird Review

On 16 March 1988 Ron Hoffman and I observed nine Tundra Swans (Cygnus columbianus) on a sandpit lake approximately 4 miles east of the I-80 interchange at North Platte. The lake's legal description is Tl3N, R29W, SW¼ of Section 8. The Swans were reported to the Nebraska Game and Parks Commission's North Platte office at 10:30 that morning by a former resident of Nebraska's Sandhills region. He thought the Swans looked identical to Trumpeter Swans (Cygnus buccinator) he had observed while living on a ranch near Hyannis. While leading us to the lake he mentioned that …

Echinococcus Vogeli Rausch And Bernstein, 1972, From The Paca, Cuniculus Paca L. (Rodentia: Dayproctidae), In The Departamento De Santa Cruz, Bolivia, Scott Lyell Gardner, Robert L. Rausch, Otto Carlos Jordan Camacho

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Among approximately 2,000 mammals examined for helminths in various regions of Bolivia during 1983-1987, cysts of Echinococcus vogeli Rausch and Bernstein, 1972, were found in a single paca, Cuniculus paca L., collected at La Laguna, Departamento de Santa Cruz (lat. 16° 36' W; long. 62° 42' S). This record, the first from Bolivia, represents a considerable extension of the known geographic range of this species in South America. Upon analysis of the morphologic characteristics of the protoscoleces derived from the cysts, the sizes of rostellar hooks from the material from the paca were found to be well within the ranges …
