Comparison Of Estimated Daughter Superiority From Pedigree Records With Daughter Evaluation, L. Dale Van Vleck, H. W. Carter

Department of Animal Science: Faculty Publications

Daughter superiorities of 240 Holstein bulls of the American Breeders Service and Eastern Artificial Insemination Cooperative (EAIC) were estimated from records of paternal sisters of the sire, dam's records, and records of daughters of the maternal grandsire. Estimated daughter superiority (EDS) was then compared with the U.S. Department of Agriculture's predicted difference for American Breeders Service bulls and with the Northeast Sire Comparison for EAIC bulls. The regression equation on estimated daughter superiority was [-84 + .561(EDS)] kg for American Breeders Service bulls and [-227 + .654(EDS)] kg for EAIC bulls. The response is not as large as theoretically predicted …

Estimation Of Heritability Of Threshold Characters, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Many traits of dairy cattle such as disease resistance and type breakdown scores may have an underlying distribution of values which are approximately normal but must be measured on a yes or no basis. Theory from literature suggests that heritability estimated from such binomial data is only z²/p(1-p) as large as heritability if it could be measured on the normal scale where z is the ordinate on the normal distribution at the threshold point corresponding to a fraction p of the population having the character. Data were generated from a pseudo-normal distribution to test this theory for estimates …

Notes On The Biology Of The Central American Squirrel, Sciurus Richmondi, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Additional specimens of Sciurus richmondi are reported, along with comments on variation, distribution, reproduction and molt in this little known squirrel. As presently understood, S. richmondi occurs only in the Caribbean rain forests of Nicaragua. Significant secondary sexual variation in adults was found only in zygomatic breadth, in which females are the larger. Available evidence reveals that the breeding season extends at least from February to September, and suggests two seasonal molts annually.

On The Ecology And Distribution Of Echinococcus Spp. (Cestoda: Taeniidae), And Characteristics Of Their Development In The Intermediate Host. Ii. Comparative Studies On The Development Of Larval E. Multilocularis Leuckart, 1863, In The Intermediate Host, Masashi Ohbayashi, Robert L. Rausch, Francis H. Fay

Harold W. Manter Laboratory of Parasitology: Faculty Publications

This paper reports the results of a comparative study of the development of the larval Echinococcus multilocularis Leuckart, 1863), and associated tissue reaction in naturally and experimentally infected mammals representing 31 species. The histogenesis of the larval cestode was traced in detail in arvicoline rodents of several species, and interspecific differences were defined.

In arvicoline rodents, the developing larva exhibited host-specific characteristics within about a month after infection was established. The tissue reaction in Microtus oeconomus was characterized by the production of a large quantity of detritus around the larva, and by the formation of a thick epithelioid zone. In …

A New Species Of Spiny Pocket Mouse (Genus Liomys) From Jalisco, Mexico, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

In the course of a systematic revision of the spiny pocket mice of the genus Liomys, a series of large, brightly colored mice from several localities in southeastern Jalisco was studied. Individuals in this series appeared to be morphologically distinct from mice typical of Liomys pictus plantinarensis Merriam. 1902, taken in the same traplines at several localities, and from specimens of Liomys irroratus jaliscensis (J. A. Allen, 1906), a taxon that also occurs in southeastern Jalisco. The current studies now have progressed to the point where the large and distinctively colored mice from Jalisco can be defined as a …

Systematics Of Southern Banner-Tailed Kangaroo Rats Of The Dipodomys Phillipsii Group, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Both nongeographic and geographic variation was assessed in southern banner-tailed kangaroo rats of the nominal species Dipodomys phillipsii and D. ornatus . Univariate and multivariate analyses were employed in consideration of geographic variation. D. ornatus is arranged as a subspecies of D. phillipsii, in which four races (phillipsii, ornatus, perotensis, and oaxacae) are recognized. Some observations on natural history also are included.

The Gonads Of The South American Dolphins, Inia Geoffrensis, Pontoporia Blainvillei, And Sotalia Fluviatilis, Richard J. Harrison, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

The appearances of the gonads are described in males and females of 18 Inia geoffrensis, 11 Pontoporia blainvillei, and eight Sotalia fluviatilis from South America. Males of I. geoffrensis become sexually active at a length of about 228 centimeters, females at 175 to 180 centimeters. Length at birth is 76 to 80 centimeters; parturition occurs from about July to September in the upper Amazon. Males of P. blainvillei are still sexually immature at a length of 128.5 centimeters, females become sexually active at a length of 137 centimeters. Off Uruguay, pregnant females have fetuses 6 centimeters in length …

Type Appraisal: Ii. Variation In Type Traits Due To Sires, Herds, And Years, H. D. Norman, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Variance components were estimated from type appraisal data to determine the importance of year, herd, sire, and herd x sire effects upon 49 body, udder, and management traits. Estimates were based on over 16,000 appraisals on daughters of Holstein artificial insemination sires. The variation explained by these effects never exceeded 34% of the total variance. Year effects were almost nonexistent (-2 to 3%). Herd effects were small for all traits except feeding speed, body weight, intensity and persistency of edema, and ketosis, and never exceeded 25%.

Most appraisal traits had low heritabilities. The estimate for milking speed was .23 while …

Type Appraisal: I. Effects Of Age And Stage-Of-Lactation On Type Ratings, H. D. Norman

Department of Animal Science: Faculty Publications

Dairy cattle type appraisal data were examined to determine whether body and udder conformation and management ratings were affected by age and period of lactation at appraisal. Data were collected from 1961 to 1968 from 188 herds having over 23,000 Holstein type appraisals. The body and udder traits were scored by scheduled appraisers, and the management traits were coded by each dairyman. Some of the 35 original traits were composed of more than one descriptive characteristic and, as a result, 49 renamed traits were derived from these.

A model was selected that considered years and herds as well as cow …

Type Appraisal: Iii. Relationships Of First Lactation Production And Type Traits With Lifetime Performance, H. D. Norman, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Phenotypic and genetic correlations were estimated between 48 type appraisal traits and first lactation milk production to determine the importance of appraisal traits in a breeding program from 5,024 records from the New York type appraisal program. Most phenotypic correlations among the type traits were near zero. Depth of udder was the appraisal trait having the highest correlation with first lactation milk (.27) and fat (.23). Multiple correlations of all appraisal traits with first lactation milk and fat were .44 and .40.

Correlations with lifetime variables were calculated from 2,068 records meeting time qualifications. Of the first lactation variables, milk …

The Somatic Chromosomes Of Some North American Marmots (Sciuridae), With Remarks On The Relationships Of Marmota Browerii Hall And Gilmore, Robert L. Rausch, Virginia R. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Karyotypes are defined for two nearctic species of marmots, Marmota olympus (2n = 40) and M. vancouverensis (2n = 42), and supplemental information is included on the karyotypes of M. flaviventris, M. monax ochracea, and M. marmota. The six North American species of Marmota (NF = 66) comprise a distinct group as compared with the middle Asian species (NF = 70) for which the karyotypes are known. Karyologic findings and zoogeographic evidence based upon the distribution of two nearctic species of host-specific cestodes indicate that M. broweri, in northern Alaska, is a pre-Würm relict. Its affinities …

Morphological Variation In Stenoderma Rufum, J, Knox Jones Jr., Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

For more than 100 years, the red fruit-eating bat, Stenoderma rufum Desmarest, 1820, was known only by a specimen of unknown geographic provenience. Anthony ( 1918, 1925) rediscovered Stenoderma in Puerto Rican cave deposits, but the first living specimens to be reported since the original description were taken on St. John in the Virgin Islands (Hall and Bee, 1960). Subsequently, Tamsitt and Valdivieso (1966) recorded living representatives from Puerto Rico-from a population later named and described as a distinctive subspecies, Stenoderma rufum darioi, by Hall and Tamsitt (1968). The latter authors also reported a specimen of S. r. rufum …

Genetic And Environmental Aspects Of Udder Infections, J. W. Wilton, L. Dale Van Vleck, R. W. Everett, R. S. Guthrie, S. J. Roberts

Department of Animal Science: Faculty Publications

Information on the presence or absence of bacterial infections and abnormal secretions in each quarter of cows in their initial survey on the New York State Veterinary College Mastitis Program was used to obtain several criteria of udder infection. Year-season and stage of lactation effects were statistically significant for several criteria of infection in first, second, and later lactation groups but did not explain much of the variation in any infection criterion. Age within first and second lactation group also accounted for little of the variation in infection although age within later lactations accounted for up to 5% of the …

Wing Loading In Plecotus Rafinesquii, Clyde Jones, Royal D. Suttkus

United States Fish and Wildlife Service: Publications

Considerable interest has developed in recent years with regard to studies of wing areas and wing loadings of North American bats (Davis and Cockrum, 19645; Jones, 1967; Davis, 1969; Farney and Fleharty, 1969). To our knowledge, such data have not been presented for Plecotus rafinesquii, one of the least known of North American species (Barbour and Davis, 1969). The purpose of this report is to provide information on flight of P. rafinesquii species, as well as adults of two other species of Plecotus.

Seventy-one P. rafinesquii were studied: five were banded and released and 66 were preserved either as skins …

The Occurrence And Significance Of Polychlorinated Biphenyls In The Environment, E.H. Dustman, L.F. Stickel, L.J. Blus, W.L. Reichel, S.N. Wiemeyer

United States Fish and Wildlife Service: Publications

The natural world today contains a vast array of man-made chemicals, many of them with biological potency in quantities scarcely measurable tow decades ago. Wild animals encounter these chemicals in multifold combination, but man's knowledge of their effects on wild species progresses haltingly. While research focused on DDT, dieldrin, and related chemicals that were obvious suspects for cause of environmental problems, other compounds, some unidentified, spread and increased.

Polychlorinated biphenyls (PCB's) constitute one such group. PCB's are products of modern industrial chemistry that have escaped to the environment by routes still largely unknown. They have become ubiquitous in the world …
