Alternate Day Protein Supplementation Of Corn Stalk Based Diets With High And Low Ruminal Escape Protein Sources, R. M. Collins, R. H. Pritchard

South Dakota Beef Report, 1991

Twenty-four crossbred wethers (88 ± .44 Ib) were utilized to determine optimal level of dietary CP when corn gluten meal (CGM) and soybean meal (SBM) based supplements were fed alternate days. Diets were arranged in a 2 x 3 factorial design with SBM and CGM fed at 8, 9 or 10% dietary CP. Supplements were top dressed on ground corn stalks at a rate of two times the daily required amount (19.78% DM basis). The collection term consisted of an 8-day total feces and urine collection. DM1 and DDMl were improved (P<.01) when CGM was fed and as dietary CP was increased by either supplement. Dry matter digestibility (DMD) decreased (P<.05) as dietary CP level increased. Neutral detergent fiber digestibility (NDFD) did not differ (P>.05) for protein source or dietary CP level. …

Total Body Water And Body Composition In Phalaropes And Other Birds, Hugh I. Ellis, Joseph R. Jehl Jr

Biology: Faculty Scholarship

Contrary to some reviews, total body water (TBW) may fall below the expected value of about 65% in birds if measured as a percentage of total body mass. However, water constitutes a relatively stable proportion (659%-70%) of body composition when measured as a percentage of lean body mass (LBM). We demonstrate this by using data from two migratory phalaropes (Phalaropus tricolor and Phalaropus lobatus), which exhibit inverse relationships between TBW and body mass and between TBW and fat content. As the phalaropes fatten before migration, lipids increase but not at the expense of water, which also increases with gains in …

Ecology Of The Green Salamander : Aneides Aeneus (Cope And Packard), In West Virginia, Ronald A. Canterbury

Theses, Dissertations and Capstones

Much has been written about the ecology of the green salamander, Aneides aeneus (Cope and Packard). The life history and ecology of southern populations of this species have been studied intensively by Gordon (1952), Woods (1968), and Snyder (1971). Gordon collected data in Highlands, North Carolina on distribution, habitat selection, population dynamics, and the ability of aeneus to withstand water loss as compared to Plethodon jordani melaventris. Woods conducted a similar study in Mississippi, and Snyder examined the adaptive brooding behavior of aeneus. In addition to these studies, further research has been conducted by Dr. Paul V. Cupp, Jr. of …

Mariculture Management For Pohnpei State, Federated States Of Micronesia, Kevin Brooks Foster

Marine Affairs Theses and Major Papers

The Marine Resources Division of Pohnpei State, Federated States of Micronesia is currently engaged in development activities that include the establishment of family scale mariculture projects for community members of remote villages and outer islands. The goal of this undertaking is to supplement subsistence and income generation ventures for community members through the wise use and exploitation of the marine environment. These aims may be jeopardized unless a management plan is devised that reflects the customary marine resource practices as embraced by islanders from each community. The intent of this thesis projects is to devise a mariculture management model that …

The Gulf Of California As A Large Marine Ecosystem, Patricia A. Morrissey

Marine Affairs Theses and Major Papers

Large marine regions characterized by unique bathymetry, hydrography and productivity, within which marine populations have adapted reproductive, growth, and feeding strategies constitute large marine ecosystems (LME) (Sherman and Alexander, 1986). The Gulf of California a semi-enclosed sea off the western coast of Mexico qualifies as a LME as it presents physical and biological characteristics not found in the adjoining Pacific. This area sustains the largest commercial fishery in the country which is the sardine fishery. the sardine population resident in the Gulf of California has coupled its reproductive and migration strategies to the environment of this region. Fluctuations of the …

Possibilities For A Common Fisheries Development And Management Policy For The Organization Of Eastern Caribbean States (O.E.C.S.), Daven C. Joseph

Marine Affairs Theses and Major Papers

The fisheries resources within the EEZs of countries in the Organization of Eastern Caribbean States is not being exploited at their maximum sustainable yield. Fisheries development has however been hampered by a history of these states, little or no sectoral development planning. If member states are to realize any increased socio-economic growth in the fisheries sector, it is imperative that a common fisheries management and development strategy be implemented by these states, in an effort to rationalize the use of scarce financial and technical resources. Such a strategy would involve the pursuance of common goals and objectives and the provision …

Striped Bass Management In Rhode Island, Thomas N. Fetherston Ii

Marine Affairs Theses and Major Papers

The management of highly migratory marine species is a difficult and complex task. No creature better represents the myriad problems faced by those attempting interstate fisheries management than the striped bass of the Atlantic coast. Their high stock levels in the late 1960s attracted unprecedented attention from commercial and sport fishermen alike. The dramatic crash of these stocks in the late 1970s, subsequent attempts at coastwide management, eventual Federal intervention and finally the rebound of the Atlantic striped bass population is an interesting case study. This paper will focus on what transpired in the State of Rhode Island during this …

Life History, Ecology, And Morphology Of The Ravine Salamander, Plethodon Richmondi, Ronnie D. Jewell

Theses, Dissertations and Capstones

The distribution of P. richmondi and P. cinereus has been of interest to herpetologist for many years. Plethodon cinereus is found throughout the state except for part of the Allegheny Plateau Province where P. richmondi occurs. There is a somewhat abrupt end to their ranges where they overlap which does not appear to be influenced by elevational differences, vegetation patterns, or general climatic changes. The propose of this study was to determine if temperature and/or moisture are limiting the distribution of P. richmondi and P. cinereus in West Virginia. The natural history of P. richmondi has not in West Virginia …

Use Of A Simulation Model To Evaluate The Influence Of Reproductive Performance And Management Decisions On Net Income In Beef Production, L. A. Werth, S. M. Azzam, Merlyn K. Nielsen, J. E. Kinder

Department of Animal Science: Faculty Publications

A stochastic dynamic model of reproduction and a deterministic cow-herd economic simulation model were used to evaluate how management decisions and reproductive performance interact to influence net income in a cow-calf operation (1,000 cows) for 1 yr of production. The stochastic model was used to determine herd performance when length of breeding season (45, 70, or 120 d) interacted with three postpartum intervals of an estrus (48, 65, or 90 d) and three conception rates at first service (60, 70, or 80%). Short, moderate, and long postpartum intervals were used to reflect differences in reproductive performance. In addition, replacement heifers …

Predation Risk And The Importance Of Cover For Juvenile Rainbow Trout In Lentic Systems, R. A. Tabor, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

Juvenile rainbow trout Oncorhynchus mykiss stocked in midelevation reservoirs in Utah inhabit shallow nearshore areas and are vulnerable to predation from piscivorous fish and birds. We determined the use and importance of nearshore habitats by (1) measuring habitat selection by, prey availability to, and feeding of juvenile rainbow trout in two reservoirs with populations of predators, and (2) measuring survival and growth rates in the presence and absence of cover in a pond experiment where adult brown trout Salmo trutta were predators. In the reservoirs juvenile rainbow trout (60–120 mm standard length) were abundant in complex inshore habitats but avoided …

The Wokalup Beef Cattle Selection Experiment, Alan Lymbery, Mick Carrick, Patrick Donnelly

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

The aim of the Department of Agriculture's long-term beef cattle selection experiment at Wokalup is to examine the effects of selection for faster-growing cattle on biological traits that may influence the productivity of a commercial beef herd. Selection lines were established from Hereford and multibreed cattle in 1977. Twelve years of selection have produced an increase in growth rate to weaning of about 120 g per day in both lines. About 40 per cent of this increase is the result of permanent genetic improvement.

We plan to compare these characteristics in cattle from the selection lines with cattle that have …

Ovulation Rate And Twinning Rate In Cattle: Heritabilities And Genetic Correlation, L. Dale Van Vleck, K. E. Gregory, S. E. Echternkamp

Department of Animal Science: Faculty Publications

Repeated measures of ovulation rate on puberal heifers should be an effective way to select for increased twinning rate. A reliable estimate of the genetic correlation between ovulation and twinning rates is needed to implement such selection and to predict its efficiency. Restricted maximum likelihood was used to estimate genetic correlations from subsets of data collected from the twinning project at the Roman L. Hruska U.S. Meat Animal Research Center. The animal model included numerator relationships among the animals and 6x4 effects of year-season of measurement, age at measurement, and birth group. Genetic correlations between averages of ovulation rates for …

Feeding Value Of Grain Sorghum For The Lactating Sow, G. F. Louis, A. J. Lewis, E. R. Peo, Jr.

Department of Animal Science: Faculty Publications

Two experiments were conducted to investigate the effects of a corn-soybean meal (CSBM) and a sorghum-soybean meal (S-SBM) diet on reproductive performance and nutrient utilization by sows. In Exp. 1,75 sows (39 gilts; 36 primiparous) were fed either a C-SBM or a S-SBM gestation diet from breeding to d 109, On d 110, sows were assigned to lactation diets; half of the sows from each dietary treatment were assigned to a lactation diet based on the opposite grain. Sow weight change from d 54 to farrowing was greater (P < .06) for sows fed S-SBM than for sows fed C-SBM. There was no difference (P > SO) in weight change of sows during lactation. Feed consumption during …

Influence Of Growth Rate And Exposure To Bulls On Age At Puberty In Beef Heifers, M. S. Roberson, M. W. Wolfe, T. T. Stumpf, L. A. Werth, Andrea S. Cupp, N. Kojima, P. L. Wolfe, Roger J. Kittok, J. E. Kinder

Department of Animal Science: Faculty Publications

Two experiments were conducted to test the following hypotheses: 1) exposure of beef heifers to sterile bulls increases the proportion of heifers attaining puberty by 14 mo of age and 2) rate of growth interacts with bull exposure to influence age at puberty in beef heifers. In Exp. I, heifers were assigned to one of two treatments: 1) heifers were exposed to bulls (BE approximately 70-d period of exposure) or 2) heifers were isolated from bulls (NE) and served as controls. In Exp. 11, heifers were assigned to either BE or NE treatments (175-d period of exposure to bulls) and …

Observations On The Natural History Of The Mediterranean Gecko, Hemidactylus Turcicus (Sauria: Gekkonidae) In Northwest Arkansas, Mark A. Paulissen, Thomas M. Buchanan

Journal of the Arkansas Academy of Science

The Mediterranean gecko, Hemidactylus turcicus, is a small nocturnal lizard introduced into the U.S. A stable population on the campus of Westark Community College in Fort Smith, Sebastian County, Arkansas represents the northernmost U.S. population presently known. We report data on microhabitat usage, feeding behavior, reproduction, and activity patterns. This gecko is active on the outside of buildings during warm months of the year and occasionally inside buildings during the winter. It is most abundant on buildings with many crevices that are used as daytime retreats. It avoids direct illumination of artificial light and usually perches at heights greater than …

Metals And Organic Compounds In Missouri River Fish In 1988 Boyd County, Nebraska To Kansas City, Missouri, George T. Allen, R. Mark Wilson

United States Fish and Wildlife Service: Publications

We conducted this project to assess the concentrations of natural and anthropogenic contaminants in fish of the Missouri River from the Nebraska/South Dakota border to Kansas City, Missouri. We collected 45 composite samples of eight fish species from nine locations on the river. We were unable to collect all species at all locations, but the collections allowed us to compare concentrations within trophic levels and at different locations. Comparisons in this project are based on concentrations in composites of fish that may have been of different ages. Also, the comparisons of different species should be treated with caution because' different …

Using Goats To Control Weeds, John Peirce

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

Feral goats are common in the woodland and tall shrubland areas of arid Australia. They survive and reproduce despite regular shooting, capture and droughts. These goats are considered vermin in Western Australia because of their competition with sheep for forage and their reputation as destroyers of vegetation. Research elsewhere, however, has indicated that it is only the uncontrolled grazing by large numbers of goats that causes degradation, in the same way that uncontrolled grazing by sheep can cause erosion. To some people, however, feral goats are a valuable source of income. They have the potential for meat sales, and they …

Reproductive Performance Of Female White-Tailed Deer On Holla Bend National Wildlife Refuge, Thomas A. Nelson

Journal of the Arkansas Academy of Science

Aspects of the reproductive biology of female white-tailed deer (Odocoileus virginianus) on Holla Bend National Wildlife Refuge were investigated by examining the reproductive tracts of 121 deer harvested during the 1985-90 archery seasons. The presence of corpora albicantia in yearlings suggested that 27% of female fawns conceived, producing a mean of 1.0 ova/breeding fawn. Pregnancy rates among yearlings and adults averaged 94% and 97%, respectively. Ovulation rates averaged 1.4 and 2.0 ova/female among yearlings and adults. Some females were ovulating in early-October, but the earliest conceptions occurred during the last week of October. The peak breeding period for yearlings and …

Human Anisakis Transmitted By Marine Food Products: Raw Facts On Sushi And Sashimi, Thomas L. Deardorff, Stephen G. Kayes, Takakazu Fukumura

Harold W. Manter Laboratory of Parasitology: Library Materials

A seafood connection with parasitic diseases in Hawaii clearly has been established and clinicians and physicians need to become more aware of this association. The risk of people in Hawaii becoming infected with these parasites from seafood products are extremely low; however, this risk increases slightly if imported fresh fishes raw or partially cooked are eaten. Prevention of these diseases, therefore, is probably best accomplished by providing continuous, accurate, and responsible information to the public concerning the health risks of eating raw fishery products; by advising the seafood industry of potential problems and methods of addressing them properly; and by …

Introgression Of Coyote Mitochondrial Dna Into Sympatric North American Gray Wolf Populations, Niles Lehman, Andrew Eisenhawer, Kimberly Hansen, L. David Mech, Rolf O. Peterson, Peter J. P. Gogan, Robert K. Wayne

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Mitochondrial DNA (mtDNA) genotypes of gray wolves and coyotes from localities throughout North America were determined using restriction fragment length polymorphisms. Of the 13 genotypes found among the wolves, 7 are clearly of coyote origin, indicating that genetic transfer of coyote mtDNA into wolf populations has occurred through hybridization. The transfer of mtDNA appears unidirectional from coyotes into wolves because no coyotes sampled have a wolf-derived mtDNA genotype. Wolves possessing coyote-derived genotypes are confined to a contiguous geographic region in Minnesota, Ontario, and Quebec, and the frequency of coyote- type mtDNA in these wolf populations is high (> 500%). The …

Eumeces Septentrionalis (Prairie Skink): Piscivory., Louis A. Somma

Papers in Herpetology

The prairie skink is a North American lizard characterized by a diet that is primarily insectivorous (Breckenridge 1943. Amer. MidI. Nat. 29:591-606). Fish have not been previously recorded as a food item (reviewed in Somma and Cochran 1989. Great Basin Nat. 49:525-534). On 3 June 1990 between 0930 and 1030 h, six Eumeces septentrionalis (three gravid females, one male, and two juveniles) were captured from amongst riprap and beneath stone slabs on the earthen dam forming the windward shoreline of Burchard lake, Pawnee Co., Nebraska (T.12N., R.10E., Sec. 4). The three females and one juvenile were placed in the …

Sterol Composition Of The Corn Root Lesion Nematode, Pratylenchus Agilis, And Corn Root Cultures, David J. Chitwood, William R. Lusby

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Sterols from mixed stages of the com root lesion nematode, Pratylenchus agilis, and uninfected corn root cultures were analyzed by gas chromatography-mass spectrometry. Twenty-eight sterols were identified in P. agilis, including nine not previously detected in nematodes. The major sterols were 24-ethylcholest-22-enol, 24-ethylcholesta-5,22-dienol, 24-methy1cholestanol, 24-ethylcholestanol, isofucostanol, and 24-ethylcholesterol. The principal corn root sterols were 24-ethylcholesta-5,22-dienol, 24-methylcholesterol, 24-ethylcholesterol, isofucosterol, and cycloartenol. Therefore, the major metabolic transformation of sterols by P. agilis was saturation of the sterol nucleus. In addition, very small amounts of 4α-methylsterols were biosynthesized by P. agilis. The 4-methylation pathway is unique to nematodes and was …
