American Woodcock Population Status, 2000, James R. Kelley Jr.

United States Fish and Wildlife Service: Publications

Singing-ground and Wing-collection surveys were conducted to assess the population status of the American woodcock (Scolopax minor). Singing-ground Survey data indicated that the number of displaying woodcock in the Eastern Region decreased 11.0% (P<0.1) from 1999 levels. In the Central Region, there was a 10.4% increase in the number of woodcock heard displaying (P<0.1) compared to 1999 levels. Trends from the Singing-ground Survey during 1990-00 were negative (-3.5 and –3.1% per year for the Eastern and Central regions, respectively; P<0.01). There were long-term (1968-00) declines (P<0.01) of 2.3% per year in the Eastern Region and 1.6% per year in the Central Region. The 1999 recruitment index for the Eastern Region (1.1 immatures per adult female) was 35% below the long-term regional average; the recruitment index for the Central Region (1.2 immatures per adult female) was 29% below the long-term regional average. The index of daily hunting success in the Eastern Region increased from 1.9 woodcock per successful hunt in 1998 to 2.0 woodcock per successful hunt in 1999, and seasonal hunting success increased 3%, from 7.2 to 7.4 woodcock per successful hunter in 1998 and 1999, respectively. In the Central Region, the daily success index in 1999 was unchanged from the 1998 index (2.1 woodcock per successful hunt) but the seasonal success index decreased 11% from 11.3 to 10.0 woodcock per successful hunter.

Details Of Extensive Movements By Minnesota Wolves (Canis Lupus), Samuel Merrill, L. David Mech

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

We used VHF, GPS and satellite radiocollars to study details of long distance movements by four Minnesota wolves (Canis lupus). Number of locations during our tracking ranged from 14 to 274. Farthest distances reached ranged from 183–494 km, and minimum distances traveled (sums of line segments) ranged from 490–4251 km. Numbers of times wolves crossed state, provincial or interstate highways ranged from 1 to 215. All four of the wolves returned to or near their natal territories after up to 179 d and at least two left again.

Cytokines In Mycoplasma Hyorhinis-Induced Arthritis In Pigs Bred Selectively For High And Low Immune Responses, N. R. Jayagopala Reddy, Bruce N. Wilkie, Peter Borgs, Bonnie A. Mallard

School of Veterinary and Biomedical Sciences: Faculty Publications

Yorkshire pigs were bred selectively for high and low immune responses (H and L pigs, respectively) based on multiple antibody (Ab) and cell-mediated immune response traits. In a previous experiment, generation 4 (G4) pigs of each line were infected with Mycoplasma hyorhinis. High responders had a more rapid and higher Ab response and less polyserositis, but arthritis was more severe in H pigs than in L pigs. To test the hypothesis that line differences were attributable to differential expression of cytokines, M. hyorhinis infection was induced in pigs of G8. Arthritis was more severe clinically (P, ≤0.05) and postmortem …

Ecogeochemistry Of The Subsurface Food Web At Ph 0–2.5 In Iron Mountain, California, U.S.A., Eleanora I. Robbins, Teresa M. Rodgers, Charles N. Alpers, D. Kirk Nordstrom

United States Geological Survey: Staff Publications

Pyrite oxidation in the underground mining environment of Iron Mountain, California, has created the most acidic pH values ever reported in aquatic systems. Sulfate values as high as 120 000 mg 1^-1 and iron as high as 27600mg 1^-1 have been measured in the mine water, which also carries abundant other dissolved metals including Al, Zn, Cu, Cd, Mn, Sb and Pb. Extreme acidity and high metal concentrations apparently do not preclude the presence of an underground acidophilic food web, which has developed with bacterial biomass at the base and heliozoans as top predators. Slimes, oil-like films, flexible …

Escherichia Coli O157:H7 In Beef Cattle Presented For Slaughter In The U.S.: Higher Prevalence Rates Than Previously Estimated, Lisa J. Gansheroff, Alison D. O'Brien

Uniformed Services University of the Health Sciences

Before 1982, the Centers for Disease Control and Prevention (CDC) had identified only one Escherichia coli isolate of the O157:H7 serotype; it had been isolated from a patient with bloody diarrhea. Then, in 1982, two outbreaks of severe bloody diarrhea occurred among people who had eaten hamburgers at a fast food chain. The CDC isolated E. coli O157:H7 from people who had become ill as well as from a hamburger patty. In 1983, Karmali et al. discovered an association between infection with E. coli that produce Shiga toxin (then called Vero toxin), including O157:H7 strains, and another severe and sometimes …

Rocky Mountain Wolf Recovery 2000 Annual Report

Rocky Mountain Wolf Recovery: Annual Reports

Gray wolf populations (Canis lupus) were extirpated from the western U.S. by the 1930s. Subsequently, wolves from Canada occasionally dispersed south into Montana and Idaho but failed to survive long enough to reproduce. Public attitudes toward predators changed and wolves received legal protection with the passage of the Endangered Species Act (ESA) in 1973. Wolves began to successfully recolonize northwest Montana in the early 1980s. By 1995, 6 packs lived entirely in northwestern Montana. In 1995 and 1996, 66 wolves from southwestern Canada were reintroduced to Yellowstone National Park (YNP) (31 wolves) and central Idaho (35 wolves).

District Court Rules In Progress Pig Case, J. David Aiken

Nebraska Swine Reports

Article 8 §12 of the Nebraska Constitution (popularly referred to as Initiative 300) establishes several requirements for corporations to legally qualify as family farm or ranch corporations in Nebraska. Under one requirement, a majority of the family farm or ranch corporation’s shareholders must be family members, “at least one of whom is a person residing on or actively engaged in the day to day labor and management of the farm or ranch.” On Sept. 16, 1998, Otoe County District Court Judge Ronald Reagan ruled in Hall v. Progress Pig that where no family member resides on the farm or ranch, …

A Review Of The Ammonia Issue And Pork Production, Janeth Colina, Austin Lewis, Phillip S. Miller

Nebraska Swine Reports

During the last few decades, an increasing interest in, and respect for, the environment has arisen. This has consequences for livestock production. Air can become polluted by noxious odors from animal husbandry. A particular example is odor emission from pig buildings, because in several parts of the world pig production has become highly specialized, industrialized and concentrated geographically. Air quality in pig facilities, as it influences the well-being of animals and workers, has become a major concern for pork producers. Odors emanating from pig slurry are an increasing source of environmental pollution as well as a nuisance to the human …

Nitrogen Balance And Growth Trials With Pigs Fed Low-Crude Protein, Amino Acid-Supplemented Diets, Jose Figueroa, Austin Lewis, Phillip S. Miller

Nebraska Swine Reports

To find out why low-crude protein, amino acid-supplemented diets often reduce growing pig performance, we conducted two experiments. In the first experiment, a nitrogen balance trial, three standard corn-soybean meal diets and three corresponding low-crude protein, amino acid-supplemented diets were used. The diets were: 14% CP and 10% CP + AA, 16% CP and 12% CP + AA, and 18% CP and 14% CP + AA, fed to 12 (90 lb) gilts in three periods of 7 d each. The amino acids lysine, tryptophan, threonine and methionine were added to low-crude protein diets to reach the same total amount as …

The Effects Of Compensatory Growth And Form Of Amino Acid Supply On Plasma Urea Concentration, Organ Weights And Carcass Characteristics In Gilts, Robert Fischer, Phillip S. Miller, Austin Lewis

Nebraska Swine Reports

An experiment was conducted to examine the effects of compensatory growth and amino acid supply on plasma urea concentration, organ weights and carcass characteristics. Gilts were fed either a corn-soybean meal diet or a corn-soybean meal diet supplemented with crystalline lysine. Pigs were randomly allotted to either a 21-day ad libitum eating period or a 42-day restricted-realimentated feeding period. The restricted-realimentated feeding period consisted of a 21-day restriction period and a 21-day ad libitum eating period (realimentation). During the restriction period, pigs were fed to maintain body weight. During week one of the ad libitum period, gilts in the restricted-realimentated …

The Use Of Plasma Urea As An Indicator Of Protein Status In Growing-Finishing Pigs, Robert Fischer, Phillip S. Miller, Austin J. Lewis

Nebraska Swine Reports

An experiment is being conducted on commercial swine operations to determine if plasma urea concentration can be used as an indicator of protein status in growing-finishing pigs. Swine producers in Eastern Nebraska are being selected to participate in this on-farm study. The experiment includes the completion of a 30-question survey and an on-farm visit for the collection of blood and feed samples. The survey includes questions about genetics, nutrition, housing and health. Preliminary results suggest that crude protein is overfed in most finishing diets. Gilts consistently have lower plasma urea concentrations than barrows when gilts and barrows are fed the …

The Investigation Of Betaine As A Growth Promotor And/Or Carcass Modifier And The Efficacy Of Betaine To Replace Methionine In Finishing Diets, Steven J. Kitt, Phillip S. Miller, Austin J. Lewis, Robert Fischer

Nebraska Swine Reports

Dietary betaine’s effect on growth performance and carcass composition of finishing barrows was investigated. Two experiments were conducted to assess whether betaine improves growth and/or carcass characteristics. In the first experiment, barrows were fed either a control diet or a diet supplemented with betaine and were either crowded or not crowded. Shoulder weight was increased in pigs fed betaine. Generally, betaine had no effect on growth performance and carcass characteristics. The second experiment attempted to assess whether betaine can replace methionine in finishing diets. Betaine tended to be associated with increased fat-free lean gain. This experiment failed to show that …

The Effect Of Oxytocin At The Time Of Insemination On Reproductive Performance — A Review, Donald G. Levis

Nebraska Swine Reports

Oxytocin is released from the brain of the sow at the time of mating in response to stimulation by the boar. It is assumed that it enhances sperm transport to the oviduct. Several investigators have studied whether injecting oxytocin into semen before artificial insemination improves farrowing rate and litter size. The conclusions from review of these studies are: 1) Adding 4 to 5 IU’s of oxytocin to a dose of semen improves farrowing rate and litter size; 2) Use of oxytocin-treated semen is more effective in multiparous sows than gilts; 3) During the summer months, oxytocin-treated semen significantly increased farrowing …

Candidate Reproductive Genes Do Not Explain Responses In Lines Selected For Ovulation Rate And Litter Size, Regina Linville, Daniel Pomp, Rodger K. Johnson

Nebraska Swine Reports

Molecular technologies have developed rapidly and provide methods to select directly for genes controlling economic traits. The swine genetic linkage map is the most highly developed of all livestock species. Positions on the chromosomes of several genes are known. Some of these genes have been shown to have direct effects on economic traits. Selection lines that differ from the control line by as much as 50% in ovulation rate and litter size exist at Nebraska. This experiment evaluated whether six specific genes that produce important proteins in reproductive processes explained responses in ovulation rate and litter size in two of …

Acylation Stimulating Protein: A Potential Regulator Of Fat Synthesis, Jess L. Miner, Carin Ramsel, Sheila Jacobi

Nebraska Swine Reports

The long term goal of this project is to understand the molecular mechanisms controlling fat synthesis. These experiments indicate that acylation stimulating protein (ASP) can stimulate the incorporation of fatty acids into lipid in cultured adipose tissue. This finding justifies a future effort to determine if manipulation of ASP can modify fat deposition.

Extruded-Expelled Soybean Meal For Pigs, Duane Reese, Larry L. Bitney

Nebraska Swine Reports

A review of the value of extruded-expelled soybean meal (ESBM) for pigs was conducted. Results from two studies where the growth performance of weanling pig was evaluated suggested that the feeding value of ESBM relative to solvent-extracted soybean meal (SSBM) is not consistent. The economic value of ESBM relative to SSBM was estimated from pig performance data and the metabolizable energy content of corn, ESBM, and SSBM. When ESBM is used to replace 44% CP SSBM in growing-finishing pig diets, it is worth 0 to $36.29 per ton more than 44% CP SSBM, assuming 44% CP SSBM and corn cost …

The Effects Of Dietary Feather Meal Concentration And Space Allocation On Performance And Carcass Characteristics Of Barrows, Kuo-Wei Ssu, Mike Brumm, Phillip S. Miller, Robert L. Fischer

Nebraska Swine Reports

An experiment was conducted to determine the effect of dietary feather meal (FM, 0 and 20% ) and space allocation (8.3 [UC] and 6.2 [C] ft²/ pig) on growth and carcass characteristics of barrows. Control barrows (0% FM and UC) had 10% higher ADFI than gilts (0 % FM and UC), but only 2.6% greater ADG. Crowded barrows fed 20% FM diet from 165 lb to slaughter had decreased ADG and ADFI compared to control barrows. Crowded barrows fed a diet with no FM had a 4.9% reduction in ADFI compared to control barrows, and crowded barrows fed …

Duration Of Prrs Virus Infections And Proportion Of Persistently Infected Pigs, R. W. Wills, Alan R. Doster, J. Galeota, J.-H. Sur, Fernando A. Osorio

Nebraska Swine Reports

The objective of this study was to more fully characterize persistent PRRSV infections in swine. Twenty-eight 35-day-old segregated-early-weaned pigs were inoculated intranasally with PRRSV. Serum and tonsil biopsy samples were collected on days 0, 7, 14, 28, and then about monthly thereafter until day 251 post inoculation (PI). Virus was isolated from serum and tonsil biopsy samples through days 28 and 56 PI, respectively. Viral RNA was detected in serum and tonsil biopsy samples by RT-PCR through day 251 PI, although no positive serum samples were detected on days 84-196 PI. Greater proportions of day 28 and 56 PI serum …

Pubertal Response In Gilts To Type And Frequency Of Boar Exposure And As Influenced By Genetic Line And Age At Initiation Of Boar Contact, Dwane R. Zimmerman, Thomas Mcgargill, Dan Cheleen

Nebraska Swine Reports

The effectiveness of twice daily (2x) vs once daily (1x) boar exposure (BE) and the possible interaction of frequency of BE with type of BE (physical, PBE vs fence-line, FBE) was evaluated in two genetic lines of the Gene Pool population (AP, selected for early age at puberty and RLS, composite of genetic lines selected for ovulation rate or litter size) differing in average pubertal age and in RLS gilts at two different ages (130 and 154 d). Gilts from the RLS line (n=128) were allotted randomly, within litter, to once or twice daily BE, PBE or FBE and to …

Policarpio Valencia's Embroidered Poetry, Annin Barrett

Textile Society of America: Symposium Proceedings

Policarpio Valencia was an artist, a poet, a salt merchant, farmer, water ditch boss, miller, town philosopher, and justice of the peace in the town of Santa Cruz, New Mexico, 25 miles north of Santa Fe. He lived in a section of Santa Cruz named El Santo Nino his whole life, from 1854 until 1931, where he married and had two children. Residents there were known as "Canaderos" because they lived close to the old Santa Cruz Mission (built in the 1730s) which was called Santa Cruz de la Canada. To get an idea of how geographically isolated …

Symbolic Content In Textile Motifs: Using The Semiotic Approach, Patricia Williams

Textile Society of America: Symposium Proceedings

John Deely (1990) stated that "the whole of human experience .. .is an interpretive structure mediated and sustained by signs". The investigation of the role of signs in the sphere of textiles is, to use Deely's phrase, one of "semiotic consciousness" or the awareness of symbolic content in clothing, cloth and textile motifs.

Semiotics is the theoretical accounting for signs and what they do. It is the study of signs and sign-using behavior including semiosis or the action of signs. The action, which may be physical or psychological, takes place between two subjects that exist physically plus a third element …

He further described the situation as a "takeover" causing "economic harm" against which those in the U.S. should be "protect[ed]." Abeita's choice of vocabulary was not out of the ordinary.¹ As a number of authors have pointed out, Mexican workers are often described as an invasionary force.² megal and legal Mexican migration and work in the U.S. or in the maquiladora manufacturing plants that have sprung up along …

Nutrients In Groundwaters Of The Conterminous United States, 1992-1995, Bernard Nolan, Jeffrey Stoner

United States Geological Survey: Staff Publications

Results of a national water quality assessment indicate that nitrate is detected in 71% of groundwater samples, more than 13 times as often as ammonia, nitrite, organic nitrogen, and orthophosphate, based on a common detection threshold of 0.2 mg/L. Shallow groundwater (typically 5 m deep or less) beneath agricultural land has the highest median nitrate concentration (3.4 mg/L), followed by shallow groundwater beneath urban land (1.6 mg/L) and deeper groundwater in major aquifers (0.48 mg/L). Nitrate exceeds the maximum contaminant level, 10 mg/L as nitrogen, in more than 15% of groundwater samples from 4 of 33 major aquifers commonly used …
