Reviews Of Glenn L. Hoffman (1967). Parasites Of North American Freshwater Fishes., John Paling Jan 1968

Reviews Of Glenn L. Hoffman (1967). Parasites Of North American Freshwater Fishes., John Paling

United States Fish and Wildlife Service: Publications

'This manual', the author explains, 'is intended to be an aid to the identification of the freshwater fish parasites of North America'. Judged by this objective, the book will be an invaluable source of reference for workers in this field. However as it does not set out to cover the ecology of fish parasites and furthermore as it concerns itself mainly with the American fauna, this book will probably have only a limited appeal to readers of this Journal.


Review Of Parasitology: Parasites Of North American Freshwater Fishes, Brother George Paul Jan 1968

Review Of Parasitology: Parasites Of North American Freshwater Fishes, Brother George Paul

United States Fish and Wildlife Service: Publications

This book is intended to serve as a manual for aiding in the identification of the freshwater fish parasites of North America. To this end an extensive key is given for each of the biological groups that have a notable number of fish parasites. In addition to this, there are sections devoted to such topics as: procedures for examining fish for parasites, methods of preserving and preparing parasites for analysis, a check list of parasites of each species of fish, and an extensive bibliographical list of references.

Harold W. Manter Laboratory of Parasitology: Library Materials

English summary

Wieczorowski S. - The alimentary tract and the lungs parasites in hares in Białystok voivodship

87 parasitic sections were made of hares coming from Białystok voivodship territory. The investigations lead to the conclusion that the hares are 100 percent invaded by parasites. Among the roundworms of the alimentary tract, the most frequent are the following: Trichostrongylus retortaeformis (78.1 percent) and Trichocephalus sylvilagi (43 percent). Coccidiosis is also widespread; it was found in 77 percent of the investigated animals.


A New Species Of Shrew (Genus Cryptotis) From Jalisco, Mexico (Mammalia: Insectivora), Hugh H. Genoways, Jerry R. Choate Dec 1967

A New Species Of Shrew (Genus Cryptotis) From Jalisco, Mexico (Mammalia: Insectivora), Hugh H. Genoways, Jerry R. Choate

University of Nebraska State Museum: Mammalogy Papers

From July 6 to 11, 1966, vertebrates were collected on Volcan de Fuego, Jalisco, for the Museum of Natural History,the University of Kansas, by Hugh H. Genoways and Percy L. Clifton. On July 10, a shrew of the genus Cryptotis was obtained on a steep slope across the valley to the north of the active cone of the volcano. The specimen was caught in a steel trap placed in the tunnel of a pocket gopher; because the opening had not been covered after the trap was set, it could not be determined whether the shrew was using the tunnel as …

Annotated Checklist Of Bats From South Dakota, J. Knox Jones Jr., Hugh H. Genoways Sep 1967

Annotated Checklist Of Bats From South Dakota, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Excepting the generalized accounts of Over and Churchill (1945), no attempt has been made previously to summarize the distribution of bats in South Dakota. In 1960, 1961, and again in 1965, field parties from the Museum of Natural History of The University of Kansas collected mammals in that state. Bats obtained by these parties, together with those on deposit in other institutions and the few specimens earlier reported from South Dakota by other workers (see cited literature), form the basis of the present report. Eleven species are here treated; two of these are represented in the state by two subspecies. …


Effects Of Dietary Safflower Oil Or Hydrogenated Coconut Oil On Growth Rate And On Some Blood And Tissue Components Of Pigs Fed A Fat-Free Diet, G. M. Babatunde, W. G. Pond, L. Krook, L. Dale Van Vleck, E. F. Walker Jr., P. Chapman Jul 1967

Effects Of Dietary Safflower Oil Or Hydrogenated Coconut Oil On Growth Rate And On Some Blood And Tissue Components Of Pigs Fed A Fat-Free Diet, G. M. Babatunde, W. G. Pond, L. Krook, L. Dale Van Vleck, E. F. Walker Jr., P. Chapman

Department of Animal Science: Faculty Publications

The effects of feeding diets containing no fat, 3% hydrogenated coconut oil (HCO) or graded levels (0.1, 0.5, 1.0 or 3%) of safflower oil (SO) on serum cholesterol, lipids and protein level; on total heart and liver cholesterol and lipid level and on growth rate and skin condition were studied in weanling Yorkshire and Yorkshire x Hampshire pigs. Pigs fed the fat-free diet for 21 weeks developed severe skin lesions not observed in pigs fed HCO diets. Highly significant elevation of serum, liver and heart lipid and liver cholesterol, and a highly significant depression of total serum protein were observed …

Notes On The Oaxacan Vole, Microtus Oaxacensis Goodwin, 1966, J. Knox Jones Jr., Hugh H. Genoways May 1967

Notes On The Oaxacan Vole, Microtus Oaxacensis Goodwin, 1966, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Goodwin (American Museum Novitates, 2243: 1-4, 1966) named Microtus oaxacensis on the basis of a single male taken in "evergreen rain forest at Tarahundi, a ranch near the village of Vista Hermosa," at an altitude of "about 5,000 feet" in the Mexican state of Oaxaca. On June 25, 1964, members of a field party from the Museum of Natural History, The University of Kansas, obtained two adult voles referable to oaxacensis in "dense cloud forest" southwest of Vista Hermosa (approximately 25 kilometers to the south of the type locality) as follows: male (KU 100046) from 6% miles SSW Vista Hermosa, …


A New Subspecies Of The Fringe-Tailed Bat, Myotis Thysanodes, From The Black Hills Of South Dakota And Wyoming, J. Knox Jones Jr., Hugh H. Genoways May 1967

A New Subspecies Of The Fringe-Tailed Bat, Myotis Thysanodes, From The Black Hills Of South Dakota And Wyoming, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

A new subspecies of Myotis thysanodes, possibly representing a disjunct population, is described from the Black Hills of South Dakota and Wyoming. The new race is compared with M. t. thysanodes and also with Myotis evotis evotis, which it superficially resembles.

Notes On Some Mammals From Nebraska, Jerry R. Choate, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

In the course of field studies in Nebraska, several noteworthy records of mammals have been obtained that add significantly to their known distribution, as shown by Jones (1964) in his "Distribution and taxonomy of mammals of Nebraska." In the following accounts all catalogue numbers refer to specimens deposited in The University of Kansas Museum of Natural History. Parenthetical page references refer to Jones (1964) unless otherwise indicated.

Taxonomic Status Of The Brush Mouse, Peromyscus Boylii Cansensis Long, 1961, Jerry R. Choate, Carleton J. Phillips, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

In the course of a study of mammals from southeastern Kansas and northeastern Oklahoma, the authors have collected specimens of the brush mouse, Peromyscus boylii cansensis Long, from its type locality and also from a place about 16 miles southwest of the type locality. The results of studies of these specimens, and of the holotype and paratypes of the subspecies, are presented and discussed herein.


Second Record Of Myotis Volans From North Dakota, Hugh H. Genoways Apr 1967

Second Record Of Myotis Volans From North Dakota, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The first record of the long-legged myotis, Myotis volans interior, in North Dakota was reported by Jones and Genoways (Trans. Kansas Acad. Sci., 69:89, 1966) on the basis of a single male from 1 mi. S and 1 mi. W Medora, Billings County. On 25 May 1966, nine adult females (KU 106932-40) of this bat were obtained by Donald R. Johnson in Granville, McHenry County. These specimens extend the known geographic distribution of M. v. interior approximately 160 miles to the northeast from the previously reported North Dakotan locality and represent the northeastern most locality of record for the …


First Classification Score And Length Of Herd Life, L. W. Specht, H. W. Carter, L. Dale Van Vleck Apr 1967

First Classification Score And Length Of Herd Life, L. W. Specht, H. W. Carter, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

The relationship of first score and length of life in the herd was measured in Holstein females two or three years of age at first classification. The regression of herd life (number of times classified) on the first over-all type score (nearly all values were between 65 and 90 points) was 1.7 months. Correlation between first classification score and herd life was approximately 0.2, indicating that less than 5% of the variation in herd life could be attributed to the relationship between first score and herd life.

Differences among herds accounted for about 10% of the total variance in overall …

Relationships Among Herd Life, Milk Production, And Calving Interval, Paul Miller, L. Dale Van Vleck, C. R. Henderson Mar 1967

Relationships Among Herd Life, Milk Production, And Calving Interval, Paul Miller, L. Dale Van Vleck, C. R. Henderson

Department of Animal Science: Faculty Publications

Whether to select for longer life in the herd or shorter calving interval depends on the genetic and phenotypic relationships among herd life, amount of milk in first lactation, and calving interval. Herd life and average calving interval are essentially phenotypically uncorrelated. The phenotypic and genetic correlations of herd life and milk in first lactation ranged from .19 to .25 and from .54 to .77, respectively. The phenotypic correlation of average calving interval and milk in first lactation ranged from .19 to .21. Estimates of the heritability of herd life ranged from .05 to .14. This heritability was reduced by …


Plant Vs. Animal Protein As A Source Of Supplemental Protein For The Gilt, Dwane R. Zimmerman, E. R. Peo, Jr., D. B. Hudman Jan 1967

Plant Vs. Animal Protein As A Source Of Supplemental Protein For The Gilt, Dwane R. Zimmerman, E. R. Peo, Jr., D. B. Hudman

Department of Animal Science: Faculty Publications

Protein of animal origin has frequently been suggested to have greater nutritional value for swine reproduction than protein of plant origin. Moustgaard (1952) reported that gilts fed a diet in which the supplemental protein was of animal origin (soured separated milk) reached puberty earlier and had a greater ovulation rate and greater embryo survival and litter size at 26 to 29 days of gestation than gilts fed a diet in which the supplemental animal protein was replaced with protein of plant origin. Most of the advantage of the animal protein diet was eliminated when the all-plant diet was supplemented with …


Sympatry Changes And Hybridization Incidence In Mallards And Black Ducks, Paul A. Johnsgard Jan 1967

Sympatry Changes And Hybridization Incidence In Mallards And Black Ducks, Paul A. Johnsgard

Papers in Ornithology

Changes in general fall and winter distributions of Mallards and Black Ducks over the past century have resulted in markedly increased sympatric contact during pair formation between these two forms, and have been responsible for increased opportunities for hybridization. Bureau of Sport Fisheries and Wildlife records of hybrids from 34 states indicate a minimal current hybridization rate that is about 4% of the frequency expected on the basis of mating according to mathematical probabilities of chance contact. Thus, hybridization is most frequent where both forms are almost equally abundant, indicating that no reinforcement of differences reducing hybridization in the primary …


1967 Beef Cattle Progress Report Of Research Activities, E. F. Frolik, H. W. Ottoson, J. L. Adams Jan 1967

1967 Beef Cattle Progress Report Of Research Activities, E. F. Frolik, H. W. Ottoson, J. L. Adams

Nebraska Beef Cattle Reports

Oral feeding of stilbestrol or implanting with stilbestrol or Synovex has resulted in increased weight gain and efficiency of gain for cattle fed finishing rations.

Combining oral feeding or stilbestrol with implanting did not give increased performance above that obtained from oral stilbestrol alone in two tests. Implanting cattle fed oral stilbestrol at the start of the feeding program with either stilbestrol or Synovex gave a similar pattern of performance to that obtained from oral stilbestrol alone.


Effect Of Plane Of Nutrition, Sex And Bodyweight On The Chemical Composition Of Yorkshire Pigs, G. M. Babatunde, W. G. Pond, L. Dale Van Vleck, G. H. Kroening, J. T. Reid Jan 1967

Effect Of Plane Of Nutrition, Sex And Bodyweight On The Chemical Composition Of Yorkshire Pigs, G. M. Babatunde, W. G. Pond, L. Dale Van Vleck, G. H. Kroening, J. T. Reid

Department of Animal Science: Faculty Publications

An experiment was carried out involving the full- vs. limited-feeding of 9 pairs of gilts and 6 of barrows from a population of closely related Yorkshire pigs from approximately 45 kg. live weight up to each of three predetermined slaughter weight groups (79, 90 and 102 kg.). The objective was to determine the effects of level of feed intake, sex and weight on the chemical composition of the empty body, edible carcass and inedible parts (offal) and the fatty acid composition of the mid-back fat. As the slaughter weight increased, the percentages of empty body, carcass and offal protein and …


Availability Of Niacin In Corn And Milo For Swine, W. G. Luce, E. R. Peo, Jr., D. B. Hudman Jan 1967

Availability Of Niacin In Corn And Milo For Swine, W. G. Luce, E. R. Peo, Jr., D. B. Hudman

Department of Animal Science: Faculty Publications

Niacin has been recognized for several years as a dietary essential for swine. Its presence in feedstuffs is well known, but the biological availability of niacin in certain cereal grains commonly fed to swine has not been clearly established. Research has been reported indicating the niacin of white corn and wheat is largely unavailable to the pig (Kodieek et al., 1956; Kodicek et al., 1959 and Luce et al., 1966). Several workers have also obtained evidence that the niacin of corn is in a bound form and largely unavailable to the rat. (Laguna and Carpenter, 1951; Pearson …


Influence Of A Dietary Supplement Of Lysine Feed At Two Levels Of Protein On Growth, Feed Efficiency And Carcass Characteristics Of Swine, M. H. Jurgens, D. B. Hudman, C. H. Adams, E. R. Peo, Jr. Jan 1967

Influence Of A Dietary Supplement Of Lysine Feed At Two Levels Of Protein On Growth, Feed Efficiency And Carcass Characteristics Of Swine, M. H. Jurgens, D. B. Hudman, C. H. Adams, E. R. Peo, Jr.

Department of Animal Science: Faculty Publications

Mertz et al. (1949) demonstrated that lysine is essential in the nutrition of swine. Since then considerable research has been conducted to determine the level of lysine needed to promote optimum growth and feed conversion in swine. Recent investigations (Crum et al., 1964; Wallace et al., 1964; Jensen et al., 1965) have been designed to measure the physical and chemical changes in the animal body which may accompany observed differences in performance due to varying lysine and protein levels.

Effect Of Artificial Insemination On Frequency Of Undesirable Recessive Genes, L. Dale Van Vleck Aug 1966

Effect Of Artificial Insemination On Frequency Of Undesirable Recessive Genes, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Reduction in the frequency of' undesirable recessive genes is examined for several combinations of initial gene frequencies and number of offspring obtained by random mating of young sires to the population. Only sires not having affected offspring are then returned to heavy use. Such selection can very rapidly reduce the number of affected offspring, if the initial gene frequency is high or if the number of tested offspring is 200-500 for lower gene frequencies. For some combinations, frequency of affected offspring in the population is higher after two or three generations of selection than in the first generation of selection. …

Records Of Bats From Western North Dakota, J. Knox Jones Jr., Hugh H. Genoways Jun 1966

Records Of Bats From Western North Dakota, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

From June 16 to 19 and again from June 24 to 29, 1965, a field party from the Museum of Natural History of The University of Kansas collected mammals along the Little Missouri River at a place 1 mi. S and 1 mi. W Medora, Billings Co., North Dakota. Among the specimens collected were representatives of five kinds of bats, including one species unreported from North Dakota, a subspecies unrecorded from there, and two species known previously from the state by a single specimen each.

Northward Dispersal Of The Hispid Cotton Rat In Nebraska And Missouri, Hugh H. Genoways, Duane A. Schlitter

University of Nebraska State Museum: Mammalogy Papers

Cockrum (1948 : 306-312 and 1952 : 184-187) summarized the northward movement of the hispid cotton rat, Sigmodon hispidus texianus, in Kansas. He showed that between 1933 and 1947 the cotton rat extended its distribution northward approximately 100 miles-from Greenwood and Allen counties north to Brown County, an average distance of seven miles per year. As of 1952, the northernmost record for the species was 5 mi. S Hiawatha, Brown County (obtained 29 November 1947), in northeastern Kansas. Trapping between 1945 and 1947 in Mitchell, Norton, and Thomas counties, in the central and western parts of northern Kansas, and …
