1080 : A Selective Poison For Pests, D R. King

Journal of the Department of Agriculture, Western Australia, Series 4

Since the 1960s, the control programmes for rabbits and dingoes in Western Australia have relied heavily on the use of sodium monofluoroacetate, more commonly known as compound 1080. Large quantaties are used each year as it is a valuable substance for the control of vertebrate pests.

Once in the animal's body 1080 is converted to fluorocitrate, a poison which is highly toxic to most mammals. Fluorocitrate blocks the Krebs cycle, a fundamental pathway of energy exchange in animals and plants. The animal dies as a result of damage to the heart, or to the brain and central nervous system, or …

Effect Of Suckling And Ovariectomy On The Control Of Luteinizing Hormone Secretion During The Postpartum Period In Beef Cows, M. Garcia-Winder, K. Imakawa, M. L. Day, D. D. Zalesky, Roger J. Kittok, J. E. Kinder

Department of Animal Science: Faculty Publications

Twenty-two mature pluriparous beef cows were randomly assigned to one of six treatments in a 2 x 3 factorial experiment in order to study the role of suckling and ovarian factors on control of the tonic and episodic release of luteinizing hormone (LH). Twelve cows remained intact (INT) and 10 were ovariectomized (OVX) within 4 days following the day of parturition (Day 0). The suckling intensities were nonsuckled (0), suckled once daily for 30 mm (1) and suckled ad libitum by two calves (2). Blood samples were collected at 1 5-mm intervals for 6 h weekly, from Days 6 to …

The Nutritional Value Of High Moisture And Reconstituted Sorghum Grain For Swine, J. D. Crenshaw, E. R. Peo, Jr., A. J. Lewis, B. D. Moser, T. D. Crenshaw

Department of Animal Science: Faculty Publications

A growing-finishing experiment involving 150 crossbred swine (replicated by time) and two metabolism experiments involving 36 crossbred barrows were conducted to determine the nutritional value of harvested high moisture (HMSG), reconstituted (RCSG) and dry sorghum grain (DSG) for swine. In Exp. 1, pigs fed HMSG diets gained the same, consumed similar amounts of feed, but less (P<.05) crude protein (equivalent dry matter basis) and had better (P<.05) feed conversion than pigs fed DSG diets.

Effects Of Inbreeding On Milk And Fat Production, Stayability, And Calving Interval Of Registered Ayrshire Cattle In The Northeastern United States, G. F. S. Hudson, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Inbreeding coefficients of 30,794 registered Ayrshire cows were calculated from relationships between sire and maternal male ancestors. Average inbreeding coefficient of all cows was less than 1% and of the 5,202 inbred cows was 5.4%. Fewer than 2% of inbred cows had coefficients greater than 15%. Percent of inbred cows increased from 23% of cows born in 1972 to 43% in 1980. Over the same period average inbreeding coefficient of all cows increased from 1.2 to 2.0%, but average coefficient of inbred cows decreased from 5.6 to 4.7%.

River Otter In Arkansas Iii. Characteristics Of Otter Latrines And Their Distribution Along Beaver-Inhabited Watercourses In Southwest Arkansas, Mark R. Karnes, C. Renn Tumlison

Journal of the Arkansas Academy of Science

Forty-one river otter (Lutra canadensis) fecal deposit (latrine) sites were located during April 1983 through March 1984 along beaver (Castor canadensis) inhabited watercourses in Clark, Nevada, and Ouachita counties, Arkansas. Latrine sizes ranged from 64 cm² to 5.01 m² (x-bar=0.30 m²; S.D. =0.88), and contained 2 to 78 scats per latrine (x-bar=9.2; S.D. = 13.8). The most common sites for latrines included elevated leaf or moss covered banks (51.2%), beaver lodges or bank dens (17.1 %), and beaver scent mounds (12.2%). Other latrine sites included felled logs over open water, bare soil along elevated banks, and exposed sandbars. Otter presence …

The Manufacture Of Cheddar Cheese Using Vacuum Concentrated Milks, Charles A. Bemis

Electronic Theses and Dissertations

The United States (US) cheese industry has grown rapidly in the past decade. From 1971 to 1981, milk fat utilization for cheese manufacture increased from 17.7 to 27.6% of the total US milk fat supply, accompanied by a 49% increase in sales of cheese per capita (34). Offsetting substantial increases in sales and prices for cheeses, there have been marked increases in the cost of labor, energy, waste treatment, raw materials, and equipment. Hence, the manufacturers are realizing narrower profit margins. As a survival mechanism, cheesemakers have sought to maximize cheese yields per unit of milk, since increases in cheese …

Environmental, Nutritional, And Physiological Factors Associated With Hoof Growth And Wear In Holstein Cows, Lisa Hartson Bemis

Electronic Theses and Dissertations

Environmental, nutritional, and physiological parameters associated with hoof growth and wear were evaluated using data from 140 Holstein cows in five herds. Growth and wear of the dorsal and lateral regions of the front and rear outside claws were measured at approximately 2 mo intervals over a 14 mo period. Housing facilities varied from continuous confinement on concrete to confinement in dirt lots and included loafing sheds, free stall barns, and one comfort stall facility with rubber mats. Lateral hoof regions grew 24% faster than dorsal regions in the front and 20% faster in the rear hooves. Rear hooves grew …

Temperature Preference And Tolerance Of Grass Carp (Ctenopharyngodon Idella), Marvin L. Galloway, Raj V. Kilambi

Journal of the Arkansas Academy of Science

Grass carp, acclimated at 24 °C, were tested for temperature preference in a laboratory, horizontal gradient tank. After a 6-day period of exploration the grass carp gravitated to a final thermal preferendum of 35 °C. In the temperature tolerance test the ultimate upper incipient lethal temperature (TL50), was estimated as 41.5°C. The results are compared to those of a similar study with hybrid carp (female grass carp x male bighead carp).

Avoidance Learning And Memory In Largemouth Bass (Micropterus Salmoides) Fed Bufo Tadpoles, Randy John Gawlik

Masters Theses

Tadpoles of the American toad (Bufo americanus) have been shown to be distasteful to largemouth bass (Micropterus salmoides) predators who learn, on the short term, to avoid them. How long bass retain this learned avoidance of Bufo larvae is unknown so an experimental design was constructed in an attempt to answer this question.

Largemouth bass were divided into four treatment groups. Two groups were initially fed exclusively larvae of Bufo americanus (one group was fed large tadpoles, the other group fed small larvae). Similarily, the other two groups were initially fed spring peeper (Hyla crucifer …

Seasonal Lekking Behavior Of The Greater Prairie-Chicken In Illinois, Scott A. Simpson

Masters Theses

Spring behavior of prairie-chickens (Tympanuchus cupido) has been studied extensively, however there is little information on fall-winter lekking activity. Greater prairie-chickens were observed weekly on a lek from 25 September 1982 to 23 June 1983 during morning and evening hours in Jasper County, Illinois. The peak number of prairie-chicken males on the lek occurred in February although hen attendance did not occur until 10 March 1983. All spring lekking activities were higher compared to that of the fall-winter period. Fall-winter lek activity was aggression which centered on probably brief, less intense male aggression which probably establishes or maintains …

Observations On Relationships Between Limb Measurements And Mode Of Locomotion In Malaysian Turtles, Duayne Nyckel

Masters Theses

Twelve Genera (spanning three Families) of Malaysian Turtles were studied to determine whether bone lengths could be correlated to mode of locomotion. Ulna, humerus, tibia, femur, coracoid (among others) were measured and results were presented graphically. Five of the genera were observed singly in a large aquarium. Data were recorded on the amount of time each spent in different locomotor modes. Both limb length data and aquarium observations suggest that turtles can be grouped into three main locomotor habits (i.e. terrestrial walking, bottomwalking, and swimming). The terrestrial group includes the genera, Geochelone, Kinixys, and Gopherus. Bottomwalkers include …

Factors Affecting Reproductive Success Of Bonytail Chubs And Razorback Suckers In Lake Mohave, Michael A. Bozek, Larry J. Paulson, James E. Deacon, U.S. Department Of Interior, Fish And Wildlife Service

Publications (WR)

Razorback suckers (Xyrauchen texanus) and bonytail chubs (Gila elegans) were once widespread throughout the Colorado River system. The ranges and populations of these native species and others have declined in the past 50 years. Bonytail chubs appear to be extremely rare and possibly nearing extinction in the Upper Colorado River Basin. The razorback sucker is widely distributed in the upper river but is considered rare throughout most of that range and is also rare in the Grand Canyon. Razorback suckers are abundant only in a few habitats in the upper river. They congregate and spawn over …

Factors In Ultrafiltration And Thermal Concentration Of Whey Affecting Commercial Lactose Crystallization, Howard Henry Bonnemann

Electronic Theses and Dissertations

The source for lactose production in the United States is almost exclusively sweet (low acid) whey which is the byproduct of cheese manufacture. Its extraction from the whey is motivated largely by pressures to utilize whey components to advantage. The ability to recover lactose efficiently is important to the manufacturers because they are in business ·to make a profit. At current market prices this profit margin will be difficult to realize unless an operation is fairly large a11d quite efficient. However, when considering the alternative of disposing of whey or its components, including lactose, as waste instead of attempting to …

Enteric Redmouth Disease Of Salmonids, G. L. Bullock

United States Fish and Wildlife Service: Publications

Enteric redmouth disease (ERM) is a systemic bacterial infection of fishes, but is principally known for its occurrence in rainbow trout, Salmo gairdneri. The disease was first reported in the 1950's by Rucker (1966), and in recognition of that fact, the causal organism was named Yersinia ruckeri by Ewing et al. (1978). Although Wagner and Perkins (1952) described a bacterial disease that produced a red-mouth condition in rainbow trout in California and Colorado, it was caused by a different bacterium; they isolated Pseudomonas hydrophila rather than Y. ruckeri.

The Effects Of Calcium Hydroxide Treatment Of Sunflower Seeds On Ration Digestibility And Rumen Parameters In Holstein Steers, Ann C. Spearow

Electronic Theses and Dissertations

Digestibilities of rations containing 10% (dry matter basis) oil-type, rolled sunflower seeds treated with three levels- of calcium hydroxide were compared using .a randomized complete block design. Forty-eight Holstein steers were fed one of six completely mixed rations consisting of (DM basis) 44% corn silage, 10% chopped alfalfa hay, and 46% concentrate mix. Concentrate mixes contained: CSM = control; SCS =control+ 22% sunflower seeds; SCL = SCS + 3.5% additional limestone; SCH2, SCH4, and SCH8 = SCS + 2, 4, and 8% calcium hydroxide (% sunflower seed DM), respectively. Total rations were isonitrogeneous at approximately 16% crude protein and isocaloric …

Survival Strategies Of Invertebrates In Disturbed Aquatic Habitats, Rosemary J. Mackay

Journal of the Minnesota Academy of Science

Disturbance in aquatic habitats may be caused by drought, flood , changes in temperature, and unusual or unnatural introductions of particulate or dissolved substances from the surrounding land. Aquatic invertebrates survive disturbance by moving to a refuge or alternative habitat or by having resistant or specially protected stages in the life cycle. Some invertebrates are able to exploit the richer and more available food materials that may result from the disturbance. Most species in disturbed aquatic habitats are efficient colonizers; they combine one or more survival strategies with high powers of dispersal, rapid growth rates, and characteristics of ecological generalists.

The Response Of Invertebrates In Temporary Vernal Wetlands To Altosid Sr-10 As Used In Mosquito Abatement Programs, Ronald W. Lawrenz

Journal of the Minnesota Academy of Science

Three temporary vernal wetlands on the Bayport Wildlife Management Area in eastern Washington County, Minnesota, were divided by sandbag barrier into treatment and control areas. Designated areas were treated with Altosid® SR-10 briquets at standard mosquito control rates. Invertebrate populations were monitored weekly using net sweeps, column samples, and ocular estimates.

The development of Eubranchtpus bundyi, Lyncerus sp, and Daphnia sp., the three major components of the invertebrate fauna, was delayed by as much as one week in site 47. Similar developmental lags were noted for E. bundyi populations in the treated portions of sites 6 and 32. Delay of …

Mosquito Control And Minnesota Amphibians, Tom R. Johnson

Journal of the Minnesota Academy of Science

Minnesota has 19 species of amphibians. Most of these animals have habitat requirements that include natural marshes, woodland ponds, and temporary pools. Amphibians need a stable and unpolluted environment. Changes in the pH of marshes or other aquatic habitats can be detrimental to Minnesota's amphibians. Habitat loss through the draining of marshes will be especially damaging. Several questions concerning mosquito control and its effects on amphibians need to be addressed.

An Analysis Of The Representation Of Memorial Events In Pigeon Short-Term Memory, Sharon Musgrave

Theses and Dissertations (Comprehensive)

There is evidence to suggest that pigeons will actively encode information on delayed matching-to-sample (DMTS) tasks either by maintaining a representation of the sample stimulus during the retention interval (retrospective processing) or by maintaining a representation of the response decision in anticipation of the upcoming comparison stimuli (prospective processing). The following experiments were conducted to determine whether processing in DMTS is retrospective or prospective in nature. Using a paradigm developed by Stonebraker (1981), pigeons were simultaneously trained on two types of tasks: identity and symbolic matching. Only one set of sample stimuli was used and followed by either the symbolic …

Dingoes And Sheep In Pastoral Areas, P C. Thomson

Journal of the Department of Agriculture, Western Australia, Series 4

Since 1975, a long-term study of dingoes in the Fortescue River area of northern Western Australia has sought to provide the detailed information necessary to devise efficient dingo management strategies.

Dingoes have been fitted with radio-transmitter collars, then tracked and observed from a specially equipped aircraft. Their movements, breeding, hunting and social behaviour have been monitered in the rugged, spinifex-covered ironstone terrain which represents typicaldingo refuge country, and in neighbouring sheep country.

Although the pastoral and agricultural industry have long recognised the need to control dingoes to protect livestock, particularily sheep, there is little published evidence about the type of …

Postnatal Osteology Of The Northern Grasshopper Mouse, Onychomys Leucogaster, Joe W. Bailey, Gary A. Heidt

Journal of the Arkansas Academy of Science

Two hundred forty-two specimens of Onychomys leucogaster, ranging in age from day of birth to the twenty-eighth day were cleared and stained using both Alizarin KOH and Alcian Blue/Alizarin-Trypsin staining methods. Thirty centers of ossification were studied. The data demonstrate the following: 1) skeletal centers of the appendicular skeleton ossify and mature earliest; 2) a new sesamoid bone lateral to the distal condyles of the femur was discovered; 3) the skeletal ossification of the baculum is present at one day of age; 4) a high degree of individual variation precludes aging of this species by skeletal maturation.

Effect Of Edwardsiella Ictaluri Infection On Plasma Corticosterone Levels In Channel Catfish (Ictalurus Punctatus), Janice L. Cooper, Stanley N. David, John K. Beadles

Journal of the Arkansas Academy of Science

Channel catfish (Ictalurus punctatus) were innoculated with a new host specific bacterium, Edwardsiella ictaluri, to observe the influence of bacterial infection on plasma corticosterone levels at various temperatures. The fish were innoculated intraperitoneally. The infected fish were separated from the controls. Plasma corticosterone concentrations were determined by radioimmunoassay. The plasma corticosterone concentrations in non-innoculated catfish were about 6.15 ng/ml and nearly 5.63 ng/ml in the infected fish. The lower level of the hormone in the infected catfish was not significantly different from the control level. High temperature was a stress factor which increased plasma corticosterone levels whereas E. ictaluri retarded …

Analysis Of Gray Fox (Urocyon Cinereoargenteus) Fur Harvests In Arkansas, Gary A. Heidt, James H. Peck, Lew Johnston

Journal of the Arkansas Academy of Science

An investigation was conducted on gray fox (Urocyon cinereoargenteus) fur harvest in Arkansas. Data were gathered from a mail survey of Arkansas trappers and from Arkansas Game and Fish Commission fur harvest records from 1939 to 1983. Analyses of these data demonstrated: 1) gray fox were abundant statewide with lower levels in the Delta region; 2) there was a need for fox trappers to keep better records on their trapping efforts, success and composition of catch, including sex and age data; 3) market price: harvest correlation was high (r = 0.956, p < .001); 4) over the past 10 years, the Ozark Mountain region provided the greatest contribution to annual fox harvests, the Ouachita Mountain and Gulf Coastal Plain regions were similar to each other, but lower than the Ozarks, and the Delta region contributed the least, but with a generally stable harvest.

The Use Of Buffer Zones In Dingo Control, P C. Thomson

Journal of the Department of Agriculture, Western Australia, Series 4

The aim of dingo control is to protect livestock, not to eliminate dingos from Australia's vast ininhabited areas. However, with labour costs rising, dingo control must become more cost effective.

In this article, P.C. Thomson discusses the "buffer zone" control strategy which involves removing dingos from a strip of country adjacent to stocked land.

Although variations of this strategy have existed for some time, detailed knowledge of dingo behaviour and movement patterns was required to ensure that the concept was soundly based. Much of this information came from a long-term study of dingos carried out in unstocked country and adjacent …

Trematode Parasites Of Marine Birds In Antarctica: The Distribution Of Gymnophallus Deliciosus (Olsson 1893), Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

During continuing studies of avian helminths at Palmer Station, Antarctica (Hoberg 1983) trematodes were found as parasites only of charadriiform birds. Digeneans were not represented in extensive collections (including several thousand specimens of helminths) from spheniscids, procellariids, and phalacrocoracids.

The pattern of distribution of trematodes in marine birds in Antarctica is influenced by the availability of suitable intermediate hosts (mollusca) and the foraging behavior of potential final hosts. Littoral environments near Palmer are structurally simple and of low diversity due to ice scouring. The limpet, Nacella polaris, is the dominant intertidal invertebrate and one of the few molluscs that …

Breeding Birds In Cedar Stands In The Great Dismal Swamp, Karen A. Terwilliger, Robert K. Rose

Biological Sciences Faculty Publications

The Great Dismal Swamp located in the coastal plain on the Virginia- North Carolina border, has long been recognized as a vegetationally distinctive region with many unusual geological and biological features. Formerly at least twice the currently estimated size of 85,000 hectares (Carter 1979), the Great Dismal Swamp is still shrinking because of a dropping water table caused by more than 200 years of logging, ditching, and other human activities. In 1973, the Union Camp Corporation donated a 19,871-hectare tract located near Suffolk, Virginia. to The Nature Conservancy, which transferred the land to the U.S. Fish and Wildlife Service. This …
