Variation Of Milk Records Within Paternal-Sib Groups, L. Dale Van Vleck Mar 1968

Variation Of Milk Records Within Paternal-Sib Groups, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Differences between daughter-dam and paternal sib estimates of heritability of first lactation milk yield have not been explained for New York data. Deviations of first lactation records from herdmate means of 155,070 artificially sired Holsteins were analyzed to examine the effect of unequal within group variances on the paternal sib estimate of heritability. The statistical model used to describe the data was yy = μ + si + eiy with σ 2yi = σ 2s + = σ2ei. Estimates of the within sire-group variances, σ1 2ei, were heterogeneous (P …

Critical Analysis Of The Control Of Malignant Effusions With Radioisotopes, Robert M. O'Bryan, Robert W. Talley, Michael J. Brennan, Emiliana San Diego Mar 1968

Critical Analysis Of The Control Of Malignant Effusions With Radioisotopes, Robert M. O'Bryan, Robert W. Talley, Michael J. Brennan, Emiliana San Diego

Henry Ford Hospital Medical Journal

Experience with radioisotope therapy at Henry Ford Hospital is reviewed here through critical analysis of results with 105 patients having recurrent malignant effusions. It is concluded that intracavitary isotope administration is of significant benefit and adds to the ease of care and comfort of such patients

Influence Of Advance In Season On Nutritive Value Of Forage Consumed By Cattle Grazing Western Nebraska Native Range, C. L. Streeter, D. C. Clanton, O. E. Hoehne

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The purpose of this study was to determine the influence of the advance in season on the nutritive value of forage consumed by cattle grazing western Nebraska summer range. Eleven digestion trials were conducted during the summer grazing season of two consecutive years.


The Nature Of Bone Resorption And Formation In Normalcy And Disease, Bruce N. Epker, Harold M. Frost Mar 1968

The Nature Of Bone Resorption And Formation In Normalcy And Disease, Bruce N. Epker, Harold M. Frost

Henry Ford Hospital Medical Journal

Classically, Howship's lacunae and osteoid seams or tissue have been used for microscopic identification of sites of bone osteoclastic and osteoblastic cell activity respectively. Recent transmitted light and blue light fluorescence microscopic study of fresh, undemineralized, specially stained and tetracycline labeled bone specimens have supported this use of these parameters of bone resorption and formation. Reports that the osteoclast is not required for bone resorption are evaluated here; it is concluded that no evidence exsists for resorption of bone tissue without osteoclasts. This does not apply to the perilacunar phenomena observed in certain well-defined situations.

The Evolution Of Duck Courtship, Paul A. Johnsgard Feb 1968

The Evolution Of Duck Courtship, Paul A. Johnsgard

Papers in Ornithology

The courtship of ducks is unusual in several aspects. In temperate zones it generally begins very early, usually on the wintering grounds, so courtship is not a manifestation of territorial proclamation and defense as is the case with many songbirds. Nor, because of its early initiation, is courtship closely correlated with gonad growth and fertilization; rather, pair formation is normally completed prior to the period of maximum gonadal activity. Therefore, reproductive behavior in ducks may be conveniently divided into an early phase of conspicuous displays associated with actual pair formation, followed by the later and less elaborate behavior patterns concerned …

Studies In Locomotion And Anatomy Of Scombroid Fishes, Harry L. Fierstine, Vladimir Walters Jan 1968

Studies In Locomotion And Anatomy Of Scombroid Fishes, Harry L. Fierstine, Vladimir Walters

Biological Sciences

Acceleration rates, analyses of body movements, and pertinent anatomical features are given for various members of the Scombridae, Istiophoridae, and Xiphiidae and are discussed in light of the modern work on smaller freshwater teleosts and marine cetaceans.

Acceleration values up to 43.1 m/sec2 are given for Thunnus albacares and Acanthocybium solanderi. Nearly 100% of the propulsive thrust comes from the caudal fin. There are two main intervertebral joints which are concerned with locomotion, a pre-peduncular and a post-peduncular joint with the body and peduncle held almost stiff, a condition similar to that described for marine cetaceans. The caudal …


Range Nutrition In An Arid Region, Lorin E. Harris Jan 1968

Range Nutrition In An Arid Region, Lorin E. Harris

Faculty Honor Lectures

On the mountains, in the valleys, on the foothills and on the deserts of the Intermountain West grow millions of tons of vegetation. The chemical energy stored bv these plants is a potential source of useful energy for man. Some of the plant material has been used for fuel, other has been used as a source of lumber, chemicals, and paper, but the major part of this vast reservO'ir is useful to man because it is utilized by livestock. This native vegetation is grazed by livestock and they convert the plant energy to' high quality, desirable food energy for man.

Three Physical Measurements Of Male White-Tailed Deer In West Virginia Correlated With Soil Fertility And Population Density, Charles C. Coffman Jan 1968

Three Physical Measurements Of Male White-Tailed Deer In West Virginia Correlated With Soil Fertility And Population Density, Charles C. Coffman

Theses, Dissertations and Capstones

Differences in the physical size of male white-tailed deer from varying parts of West Virginia were known to exist a considerable number of years before any sophisticated attempts were made to explain them. Prior to 1940, the state's deer herd had been making a slow, but increasingly steady, comeback from a period of extreme scarcity around the turn of the century. To supplement the original remaining stock, shown in Figure 1, page 2, a deer restocking program was initiated in 1923. In 1937, federal legislation, in the form of the Federal Aid to Wildlife Restoration Act, gave added support to …


A Preliminary Study On Ensiling Aspen Bark, Charles Helleloid, John Klow, Gary Pullar, John Veranth Jan 1968

A Preliminary Study On Ensiling Aspen Bark, Charles Helleloid, John Klow, Gary Pullar, John Veranth

Journal of the Minnesota Academy of Science

A preliminary study was conducted on the ensiling of aspen bark in laboratory silos for the production of animal food. Several types of silo, both with and without an enzyme preparation, were tested. Results of physical and chemical tests on the contents indicate that definite changes occur when bark is ensiled, and that these changes differ with ensiling conditions. Several of these changes suggest possibilities for future research.


Biological Aspects Of Heat Pollution, Theodore Olson Jan 1968

Biological Aspects Of Heat Pollution, Theodore Olson

Journal of the Minnesota Academy of Science

The importance of temperature as an environmental factor has long been recognized by the ecologist, and its special impact upon the aquatic ecosystem has been of interest to aquatic biologists since they first began to observe interactions between living things and the physical environment. Interest in water temperatures as an environmental factor has recently become more widespread; and one aspect of the phenomenon, namely "thermal pollution," has attracted special attention.
