The Effect Of Prostaglandin Inhibitor On Pregnancy Rates Of Heifer Embryo Transfer Recipients, Jared William Mcnaughtan

Theses and Dissertations

Manipulation of the reproductive tract results in increased levels of prostaglandin, which may, in turn, reduce pregnancy rates in embryo recipients. Administration of a prostaglandin inhibitor prior to embryo transfer improves pregnancy rates in cows. Embryo transfer into heifers is more difficult and often requires additional manipulation of the uterus. This study was designed to determine whether administration of the prostaglandin inhibitor, flunixin meglumine, immediately prior to embryo transfer increases pregnancy rates in heifers. Heifers (n=466) were divided into two equal groups based on BCS (range=6-7) and weight (range=256-455). Estrus was synchronized in heifers by giving two injections of prostaglandin …

Origin And Evolution Of Large Brains In Toothed Whales, Lori Marino, Daniel W. Mcshea, Mark D. Uhen

Veterinary Science and Medicine Collection

Toothed whales (order Cetacea: suborder Odontoceti) are highly encephalized, possessing brains that are significantly larger than expected for their body sizes. In particular, the odontocete superfamily Delphinoidea (dolphins, porpoises, belugas, and narwhals) comprises numerous species with encephalization levels second only to modern humans and greater than all other mammals. Odontocetes have also demonstrated behavioral faculties previously only ascribed to humans and, to some extent, other great apes. How did the large brains of odontocetes evolve? To begin to investigate this question, we quantified and averaged estimates of brain and body size for 36 fossil cetacean species using computed tomography and …

Size Matters: A Test Of Boldness In Eight Populations Of The Poeciliid Brachyraphis Episcopi, Culum Brown, Victoria Braithwaite

Sentience Collection

Individual variation in behaviour within populations may be explained in part by demographics and long-term, stable individual psychological differences. We examined the relation between boldness (taken as the time to emerge from a shelter and explore a novel environment) and body size in eight populations of the poeciliid Brachyraphis episcopi originating from sites upstream and downstream of waterfalls in four rivers that run into the Panama Canal. The relation between body size and time to emerge from a shelter was positive, with larger fish taking longer to emerge. This relation differed between downstream and upstream sites, being significant in the …

Fisheries Occasional Paper No. 14 - Department Of Fisheries Stakeholder Survey 2004, Tara Baharthah

Fisheries Occasional Publications

A telephone survey of Department of Fisheries' stakeholders was conducted in August 2004 in order to evaluate their perception of the Department's management of commercial and recreational fishing, pearling and aquaculture, and fish and fish habitat protection. The survey also assessed satisfaction with the level of service provided to stakeholders and their involvement in decision making processes.

The results of this survey were compared to a similar survey conducted during 2002 and a survey of the general public conducted during 2004.

The Ecology And Relationships Of Chiropteran Ectoparasitic Communities Of Indiana, Christopher Michael Ritzi

All-Inclusive List of Electronic Theses and Dissertations

The ectoparasites of bats are an important and largely unstudied area of mammalian ecology. The structure of ectoparasitic communities on bats, and their interactions with their hosts, may help in the understanding of roosting ecology, pa1iurition, and other aspects of host natural history. In this study, a vigorous survey of the ectoparasitic fauna of the bats ofindiana was undertaken, to determine if changes in species composition has occurred over the past 30 years. This survey resulted in the recovery of 51,980 parasites of 13 families from 2,816 host individuals of l O species, documenting 16 new host records and 14 …

The 2002 Nebraska Nest Report, Wayne Mollhoff

Nebraska Bird Review

In contrast to last year, with "the winter that wouldn't end," this breeding season began with a "spring that wouldn't begin." The winter was mild and uneventful, but although the spring was neither cold nor stormy, the usual warm-up did not come, and when the weather finally warmed in May, it brought no moisture. The resulting drought was worst in the west and southwest, areas that had already been abnormally dry for several years. In mid-June in the southern Panhandle, many ranchers were still feeding hay to the cattle because the grass simply did not grow. The dry conditions surely …

Use Of Cre Recombinase And Sb Transposase To Engineer Transgenic Zebrafish, Jie Dong

All-Inclusive List of Electronic Theses and Dissertations

Current transgenesis has become easier for certain species due to the recent development of exogenous non site-specific recombination systems such as Sleeping Beauty (SB) transposon, and site-specific recombination systems such as Cre-loxP. Such recombination systems overcame two major problems caused by conventional transgenesis, position effect and copy number effect. SB is a reconstructed fish transposon that has shown to efficiently insert transgenes into heterologous mammalian chromosomes. The Cre-loxP system is frequently used to delete a given sequence from the genome or to target the integration of foreign DNA. The use of both systems in combination, however, has not yet been …

Lake Mcconaughy And Nebraska Piping Plover Recovery Goals, Mark M. Peyton

Nebraska Bird Review

Since 1992 the Central Nebraska Public Power and Irrigation District (Central) has protected and monitored nesting Piping Plovers along the shore of Lake McConaughy (Keith County, Nebraska). Over those 13 seasons, Central monitored 849 Piping Plover nests and documented the successful fledging (successful fledging is defined as a chick at least 24 days old, or one observed flying) of 1,237 Piping Plover chicks (Table 1), making Lake McConaughy one of the most productive nesting areas for Piping Plovers in Nebraska. The following is a documentation of the contributions of Lake McConaughy to the recovery goals for Piping Plovers in Nebraska. …

Fall Field Report, August-November 2004, W. Ross Silcock

Nebraska Bird Review

The fall season is a mix of summer, fall migration, and winter. Thus there are breeding records of interest, such as Mississippi Kites nesting at Red Cloud, only the 2nd known location in Nebraska, and only the 3rd documented breeding record for Northern Parula, despite its common summer residency. Fall migration generates early arrival dates, high counts, and late departure dates, the last seemingly more numerous as our average temperatures increase. Included in the late departure category were several late shorebirds, Great Egret and White-faced Ibis, and even the latest ever Black-throated Blue Warbler.

Counts of interest were 3000 Double-crested …

Does Birding Have A Future?, Rick Wright

Nebraska Bird Review

Does birding have a future?

Now this might seem an odd question, even an absurd question, to pose to an audience like this, and the answer might seem obvious. How could birding not have a future when we, all of us, are birders who bird, and when survey after recent survey assures us that our numbers are growing, our diversity increasing, and our economic and ethical contributions to American society ever more conspicuous. Does birding have a future? The simple answer is yes.

That's the simple answer. The more interesting answer is yes-yes, but. Yes, birding has a future, but …

Biology Faculty Articles

Eight traditional subspecies of tiger (Panthera tigris), of which three recently became extinct, are commonly recognized on the basis of geographic isolation and morphological characteristics. To investigate the species' evolutionary history and to establish objective methods for subspecies recognition, voucher specimens of blood, skin, hair, and/or skin biopsies from 134 tigers with verified geographic origins or heritage across the whole distribution range were examined for three molecular markers: (1) 4.0 kb of mitochondrial DNA (mtDNA) sequence; (2) allele variation in the nuclear major histocompatibility complex class II DRB gene; and (3) composite nuclear microsatellite genotypes based on 30 loci. Relatively …

Follicular Development And Maturation In Gilts Selected For An Index Of High Ovulation Rate And High Prenatal Survival, H.-W. Yen, J. J. Ford, D. R. Zimmerman, R. K. Johnson

Department of Animal Science: Faculty Publications

Seventy-one 10th-generation gilts from White Line-1 (WL-1 = randomly selected control line) and White Line-2 (WL-2 = selected for an index of ovulation rate and prenatal survival rate) were used to compare the pattern of follicular development and atresia during the follicular phase of the estrous cycle. Gilts were treated with PGF_2α on d 13 of the estrous cycle (d 0 of induced follicular development) to induce luteolysis and assigned randomly within line and sire for ovary recovery on d 0, 2, 3, 4, 5, and the day after estrus. Ovaries were evaluated for numbers of corpora albicantia and …

Microarray Profiling For Differential Gene Expression In Ovaries And Ovarian, A. R. Caetano, R. K. Johnson, J. J. Ford, Daniel Pomp

Department of Animal Science: Faculty Publications

A unique index line of pigs created by long-term selection ovulates on average 6.7 more ova than its randomly selected control line. Expression profiling experiments were conducted to identify differentially expressed genes in ovarian tissues of the index and control lines during days 2–6 of the follicular phase of the estrous cycle. Fluorescently labeled cDNAs derived from ovary and follicle RNA were cohybridized on microarray slides (n = 90) containing 4608 follicle-derived probes printed in duplicate. Statistical analysis of the resulting ~1.6 million data points with a mixed-model approach identified 88 and 74 unique probes, representing 71 and 59 …

A Large-Sample Qtl Study In Mice: Iii. Reproduction, Joao L. Rocha, Eugene J. Eisen, Frank Siewerdt, L. Dale Van Vleck, Daniel Pomp

Department of Animal Science: Faculty Publications

Using lines of mice having undergone long-term selection for high and low growth, a large-sample (n ≈ 1000 F₂) experiment was conducted to gain further understanding of the genetic architecture of complex polygenic traits. Composite interval mapping on data from 10-week-old F2 females (n = 439) detected 15 quantitative trait loci (QTLs) on 5 chromosomes that influence reproduction traits characterized at day 16 of gestation. These QTL are broadly categorized into two groups: those where effects on the number of live fetuses (LF) were accompanied by parallel effects on the number of dead fetuses (DF), and those free …

Fisheries Research Contract Report No. 10 - Mother-Of-Pearl Shell (Pinctada Maxima): Stock Evaluation For Management And Future Harvesting In Western Australia, Anthony M. Hart, Kim J. Friedman

Fisheries Research Contract Reports

The West Australian Pearling industry is one of Australia's most valuable aquaculture industries, currently generating around $120 - $160 million annually. The majority of pearl shell used to culture pearls come from the pearling beds in the inshore waters near Broome. The fishery for pearl oysters preferentially targets smaller (120mm - 165mm DVM) shell (hereafter defined as 'culture' shell), that are more suitable for culturing of pearls, leaving larger MOP oysters (175mm+) on the pearling grounds. These larger pearl oysters, the majority of which are female (protandric hermaphrodites), form a major component of the broodstock for the

fishery. Although MOP …

Eradicating Footrot From Western Australia - A Farmer's Guide, Department Of Agriculture, Western Australia

Agriculture reports

Virulent footrot can occur on any farm in the medium to high rainfall zone. Persons who regularly buy and sell sheep take a greater risk, but even properties with a closed breeding flock are at risk from stray sheep. People often associate footrot with properties managed by inefficient farmers. This is a false belief. Many good farmers have found the disease in their sheep, including high profile studs. Footrot can strike anywhere and often without warning. It is important to remember that once it is found; getting to know and understand the disease will help you to beat it. A …

Apparent Sibling Rivalry In The Freshwater Clam Sphaerium Striatinum, Mark Beekey, Ronald H. Karlson

Biology Faculty Publications

In Sphaerium striatinum, a freshwater brooding bivalve, up to 97.5% of offspring that adults initially produce fail to reach independence. Marsupial sacs, specialized extensions of gill filaments that act as nurseries, initially contain multiple offspring in various sizes and stages of development. However, by the time offspring reach later stages of development, marsupial sacs typically contain only one offspring. Brood mortality is hypothesized to be the result of competition among embryos for nutrients and/or space. Sphaeriid eggs do not contain enough yolk for offspring to complete development. Adults supply additional nutrients required to reach independence. Brood capacity is limited by …
