Reproductive Biology Of Black Bears In The Smoky Mountains Of Tennessee, John Heinrich Eiler Jun 1981

Reproductive Biology Of Black Bears In The Smoky Mountains Of Tennessee, John Heinrich Eiler

Masters Theses

Information related to the reproductive biology of female black bears (Ursus americanus) was collected in the Smoky Mountains of Tennessee. Denning and weight information were also collected.

The majority of females utilized tree dens. The denning period averaged 114 days, with most females entering dens during the first 3 weeks of December and emerging from dens between the first and last week of April. Females with newborn cubs denned longer and emerged from dens later than females without offspring. The date of den emergence for females for females was used to effectively predict reproductive condition (with newborn cubs or without …

The Psychology Of Euthanizing Animals – The Emotional Components, Charles E. Owens, Ricky Davis, Bill Smith Jan 1981

The Psychology Of Euthanizing Animals – The Emotional Components, Charles E. Owens, Ricky Davis, Bill Smith

International Journal for the Study of Animal Problems

The emotional effects of euthanizing unwanted animals on professional animal control personnel are examined using written statements and oral discussions of twenty-six euthanasia technicians at a workshop during a national session

of the Animal Control Academy (Tuscaloosa, AL]. Emotional conflicts arise in significant part from the dilemma that the same public responsible for the problem of unwanted animals also has a markedly negative perception of euthanasia,

and by extension, of those who perform euthanasia. During discussions, the euthanasia technicians revealed various strategies for coping with feelings of isolation, alienation, and sorrow. These included intellectualization, avoidance of unnecessary contact with the …


Breeding And Use Of Nonhuman Primates In The Usa, Joe R. Held Jan 1981

Breeding And Use Of Nonhuman Primates In The Usa, Joe R. Held

International Journal for the Study of Animal Problems

Several species of nonhuman primates, each possessing specific characteristics of particular value, are used by the United States biomedical community in various health-related activities. These animals are man's closest relatives and are indispensable in understanding and controlling human health problems. The destruction of primate habitats and embargoes on the export of primates from source countries have decreased the supply of these animals. The inadequate and erratic supply of these resources threatens the continuation of many ongoing and new activities contributing to improving human health. In the U.S., a program has been developed to meet the health needs of primates:

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Mit zwei großen komplexen biologischen Sammelexpeditionen 1962 und 1964 der Akademien der Wissenschaften der DDR und MVR in die Süd- und Westmongolei wurde der Grundstein für die kontinuierliche Entwicklung der Wissenschaftskooperation auf biologischem Gebiet zwischen beiden Staaten gelegt. Die Kollektionen wurden zum Grundstock eines aufzubauenden botanischen und zoologischen Sammlungsfundus in Ulan-Bator. Durch den Freundschaftsvertrag zwischen den Universitäiten Halle und Ulan-Bator im Jahre 1967 wurden die Kontakte neu aktiviert. Nach anfänglich sporadischen Studienaufenthalten und Expeditionsreisen von Einzelwissenschaftlern wurde das Forschungsprogramm auf biologischem Gebiet im Rahmen dieses Freundschaftsvertrages recht bald auf Schwerpunktaufgaben ausgerichtet, die sich lückenlos in das Forschungsprofil des mongolischen Vertragspartners …


Der Stand Der Hydrobiologischen Forschungen In Der Mongolischen Volksrepublik, Ayuur Dulmaa Jan 1981

Der Stand Der Hydrobiologischen Forschungen In Der Mongolischen Volksrepublik, Ayuur Dulmaa

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Die Entwicklung der Hydrobiologie in der MVR vollzog sich unter ständiger Orientierung an den volkswirtschaftlichen Interessen des Landes. Deshalb wurde neben grundlegenden Forschungen zu Fauna und Ökologie der Gewässer besonderes Gewicht auf die Akklimutisierung von Nutzfischen gelegt. Die dazu notwendigen Kenntnisse der hydrobiologisch bisher weitgehend unerforschten Seen der Mongolei erbrachten mehrjährige Expeditionen in verschiedenen Gebieten des Landes. Den gemeinsamen Biologischen Chövsgöl-Expeditionen der Universitäten Irkutsk und Ulan-Balor kommt dabei eine besondere Rolle zu. Am See Chövsgöl entstand auch die erste hydrobiologische Station der MVR. Die rasche Entfaltung der Hydrobiologie in den letzten zwanzig Jahren dokumentiert eine Reihe bedeutender wissenschaftlicher Publikationen ebenso …

First paragraph:

Wenn die Mongolische Staatliche Universität Ulan-Bator ihrem 40. Gründungstag entgegengeht, der folgerichtig in dem revolutionären Aufbruch aus einer alten Geschichte des mongolischen Volkes in eine sozialistische Gessellschaft begründet liegt, so treffen sich seit über einem Jahrzehnt in diesem wissenschaftshistorischen Zeitraum auch Wissenschaftler und Studenten der Martin-Luther-Universität Halle-Wittenberg mit ihren mongolischen Kollegen und Freunden der Mongolischen Staatlichen Universität Ulan-Bator zu geistiger Begegnung und gemeinsamer wissenschaftlicher Arbeit. Sie entspringt den gleichen Zielen einer sozialistischen Gesellschaft, Bildung, Kultur und Wissenschaft zur allseitigen Entwicklung der Persönlichkeit, zur stetigen Verbesserung des Volkswohlstandes, für Völkerverständigung und sozial-historischen Fortschritt zu entfalten.

Die Erforschung Der Herpetofauna Der Mongolischen Volksrepublik: Situation Und Perspektiven, Günther Peters

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

First paragraph:

Die Landschaften der Mongolei sind arm an Reptilien- und Amphibienarten. Dieser Umstand mag die Frage aufwerfen, ob herpetologische Untersuchungen in Beschränkung auf das Territorium der MVR eine nennenswerte Perspektive haben könnten, nachdem Artenspektrum und Verbteitung der Species annähernd vollständig erkundet sind. Ein Herpetologe wird zweifellos für seine Arbeit auch in diesem Land eine Zukunft sehen, doch muß wohl von vornherein eingestanden werden, daß das Volumen der Probleme dieses Faches hinter denen der übrigen Disziplinen der Vertebratenzoologie und der Entomologie in einem bescheidenerem Rahmen verbleibt. Dies gilt sowohl im rein wissenschaftlichen als erst recht auch im angewandten Bereich ihrer …


Social And Cognitive Capabilities Of Nonhuman Primates: Lessons From The Wild To Captivity, William C. Mcgrew Jan 1981

Social And Cognitive Capabilities Of Nonhuman Primates: Lessons From The Wild To Captivity, William C. Mcgrew

Sentience Collection

All anthropoid primates in nature lead highly sociable lives. In infancy and childhood this is characterized by stability and familiarity for both sexes; in adulthood either one or the other sex changes groups. The natal group provides a social network of matrilineal kinship; after sexual maturity incest avoidance and exogamy are the rule. Important differences exist across species and between the sexes in mating strategies. In most species, males emigrate, but in others females do so. Male sexual behavior is based on competition between peers; females exercise choice in selecting sexual partners. Normal development of sexual behavior and maternal caretaking …


Use Of Kamar® Heatmount Detectors In Beef Cattle Synchronized With Lutalyse®, G.H. Kiracofe, M. Heekin, Kenneth G. Odde, M. King Jan 1981

Use Of Kamar® Heatmount Detectors In Beef Cattle Synchronized With Lutalyse®, G.H. Kiracofe, M. Heekin, Kenneth G. Odde, M. King

Kansas Agricultural Experiment Station Research Reports

The ability of the Kamar Heatmount Detector to identify cows ready for insemination 80 hours after two Lutalyse injections was tested with 439 beef cows and heifers. The detector was placed on the rump at the second injection and was "read" at insemination. Conception rate from the 80-hour timed insemination for cows with red (activated) and lost detectors was 56.5% compared with 7.6% of the cows with white detectors.


Alfalfa Haylage For Sows During Gestation (1981), G L. Allee Jan 1981

Alfalfa Haylage For Sows During Gestation (1981), G L. Allee

Kansas Agricultural Experiment Station Research Reports

Digestion and nitrogen retention studies suggest that three pounds of good quality alfalfa haylage dry matter and two pounds of a grain, mineral, and vitamin premix will meet the nutritional requirements of sows during gestation. Quality of the haylage is extremely important for sows. Third-cutting alfalfa had a higher digestible energy and digestible protein than did the more mature first-cutting haylage. The digestible energy of alfalfa haylage for sows was 954 to 1,096 Kcal/pound. Sows fed alfalfa haylage and ONLY ONE pound of a grain vitamin and mineral premix farrowed pigs that were lighter at birth than pigs farrowed from …


The Toxicity Of Liquid Supplements Containing Urea, E.E. Bartley Jan 1981

The Toxicity Of Liquid Supplements Containing Urea, E.E. Bartley

Kansas Agricultural Experiment Station Research Reports

Liquid supplement manufacturers must provide a product that is effectively utilized and is nontoxic. Toxicity can be reduced if the supplement's pH is below 3.8, but low pH alone does not improve nutritive value. A good fermentable source of carbohydrate, like molasses or cooked starch, should be provided in adequate amount. When water or lignin sulfonates are substituted for good carbohydrate, urea utilization is reduced and the risk of toxicity is increased. Cattle that are hungry or starved from blizzard conditions or feed restriction are much more susceptible to ammonia toxicity than cattle kept full, so limit the availability of …


Effect Of Limited Suckling On Reproductive Performance And Milk Production Of Cows And Weight Gains And Suckling Behavior Of Calves, Kenneth G. Odde, G.H. Kiracofe, R.R. Schalles Jan 1981

Effect Of Limited Suckling On Reproductive Performance And Milk Production Of Cows And Weight Gains And Suckling Behavior Of Calves, Kenneth G. Odde, G.H. Kiracofe, R.R. Schalles

Kansas Agricultural Experiment Station Research Reports

We used 109 Polled Hereford and percentage Simmental cows to evaluate limited suckling as an aid to induce cows to cycle after calving. Cows were allotted to: 1. once daily suckle; 2. twice daily suckle; 3. 48 hr calf removal (just before breeding season); and 4. controls (suckle ad libitum). Half of each group was implanted with Norgestomet 9 days before the breeding season. Limited suckling increased the number of cows showing estrus and conceiving early in the breeding season, and Norgestomet increased the percentage pregnant the first 21 days of the breeding season.


Effects Of Weaning Weight On Reproductive Performance In Beef Heifers, L.R. Sprott, L.R. Corah, G.H. Kiracofe Jan 1981

Effects Of Weaning Weight On Reproductive Performance In Beef Heifers, L.R. Sprott, L.R. Corah, G.H. Kiracofe

Kansas Agricultural Experiment Station Research Reports

Fertility during the first two breeding seasons was not affected by the dam's weaning weight, but lightest heifers at weaning reached puberty later, had smaller pelvic areas at calving, more difficult deliveries, had more calves die, and weaned a smaller percentage of their calves.

Commercial Silage Additive Trials, K. Bolsen Jan 1981

Commercial Silage Additive Trials, K. Bolsen

Kansas Agricultural Experiment Station Research Reports

Most Kansas grown crops can be harvested, stored, and fed as silage. A good silage fermentation should produce a well-preserved, palatable feed with minimum nutrient loss, but making a good silage requires good management. The crop must be harvested at the proper maturity and moisture, be finely chopped, and be tightly packed in the silo. Numerous commercial silage additives, whose manufacturers make various claims for improving silage quality, are available. Last year, we reported on 5 trials involving six commercial additives (Report of Progress 377). Each additive improved the silage in at least one of the four criteria we evaluate.

Steer Gains On Burned And Nonburned Bluestem Pasture And Reimplanting With Ralgro At Mid-Summer, E.F. Smith, R. Behnke, Clenton E. Owensby Jan 1981

Steer Gains On Burned And Nonburned Bluestem Pasture And Reimplanting With Ralgro At Mid-Summer, E.F. Smith, R. Behnke, Clenton E. Owensby

Kansas Agricultural Experiment Station Research Reports

Steers on a late spring burned bluestem pasture gained 1.4 lbs daily during the summer compared with 1.0 lb. by steers on a nonburned pasture. All steers were implanted with Ralgro at the start of the grazing season (May 1) and half in each pasture were reimplanted July 15. Reimplanting did not affect weight gain.


Intermittant Antibiotics Vs. Continuous Antibiotics For The Finishing Pig (1981), Robert H. Hines Jan 1981

Intermittant Antibiotics Vs. Continuous Antibiotics For The Finishing Pig (1981), Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

The use of low or high level antibiotics fed continuously or intermittantly (2 week rotation) to 310 finishing pigs was evaluated in two trials. No significant improvements were noted for rate of gain or feed per lb. of gain in pigs fed antibiotics either continuously or intermittantly, as compared with pigs fed no antibiotics. No difference in performance was observed in pigs fed antibiotics intermittantly or continuously. The rotation of two high level antibiotics in Trial II did not significantly improve the performance of pigs over that of pigs fed no antibiotics.; Swine Day, Manhattan, KS, November 12, 1981


Effect Of Diet Complexity And Physical Form On Performance Of Starter Pigs And On Efficiency Of Feed Processing (1981), S Pollmann, Keith C. Behnke, G Allee Jan 1981

Effect Of Diet Complexity And Physical Form On Performance Of Starter Pigs And On Efficiency Of Feed Processing (1981), S Pollmann, Keith C. Behnke, G Allee

Kansas Agricultural Experiment Station Research Reports

In two trials 330 crossbred pigs averaging 12 pounds were used to evaluate the effect of starter diet complexity and physical form on average daily gain, feed efficiency, and cost of gain. In a processing efficiency trial, pellet durability, amount fines returned, and power consumption were determined. A diet with milo-soybean meal as a basis (simple) was compared with one containing 3% tallow and 5% dried whey in milo-soybean meal (complex). Each was processed into three physical forms: meal, pellet, and crumble. Adding 3% tallow and 5% whey to milo-soybean meal diet did not improve performance of the starter pigs …


Collastoma-Kozloffi Sp-N, A Neorhabdocoel Turbellarian From The Intestine Of The Sipunculan Themiste-Dyscrita, Clinton A. Westervelt Jan 1981

Collastoma-Kozloffi Sp-N, A Neorhabdocoel Turbellarian From The Intestine Of The Sipunculan Themiste-Dyscrita, Clinton A. Westervelt

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Collastoma kozloffi sp. n. is described from the intestine of the sipunculan, Themiste dyscrita, collected at three localities on the Oregon coast. This species is particularly distinctive because of its large egg capsule (length about 400-500 ,m). The relationships of the five known species of Collastoma are discussed.


Estrous Synchronization And Fertility In Allyl Trenbolone-Treated Gilts (1981), Jeffrey S. Stevenson, W E. Schmidt, Duane L. Davis Jan 1981

Estrous Synchronization And Fertility In Allyl Trenbolone-Treated Gilts (1981), Jeffrey S. Stevenson, W E. Schmidt, Duane L. Davis

Kansas Agricultural Experiment Station Research Reports

Onset of estrus in gilts fed allyl-trenbolone for either 14 or 18 days was controlled effectively. The stage of the cycle at the beginning of treatment had little effect on the synchronization response. More than 97% of the treated gilts showed estrus within 3 to 8 days after the last progestagen feeding. Treatment did not affect gestation length, farrowing rate, or litter size.; Swine Day, Manhattan, KS, November 12, 1981


Prostaglandin F2Α To Induce Farrowing In Sows (1981), Duane L. Davis Jan 1981

Prostaglandin F2Α To Induce Farrowing In Sows (1981), Duane L. Davis

Kansas Agricultural Experiment Station Research Reports

Alternate groups of sows were synchronized, with prostaglandin, to farrow within a certain time or to serve as controls. The objective was to determine if baby-pig survival or litter-weaning weight would be improved by such group farrowing. Results indicated no improvement in those traits; therefore, if prostaglandin is used under the conditions of this experiment, its cost will have to be justified by other considerations.; Swine Day, Manhattan, KS, November 12, 1981
