Measures Of Weight Distribution Of Dairy Cows To Detect Lameness And The Presence Of Hoof Lesions, M. Pastell, L. Hänninen, A. M. De Passillé, J. Rushen

Farm Animal Welfare Collection

There is increasing interest in automated methods of detecting lame cows. Hoof lesion data and measures of weight distribution from 61 lactating cows were examined in this study. Lame cows were identified with different numerical rating scores (NRS) used as thresholds (NRS >3 and NRS ≥3.5) for lameness. The ratio of weight applied to a pair of legs (LWR) when the cow was standing was calculated using a special weigh scale, and the cows were gait scored using a 1 to 5 NRS. Hoof lesions were scored and the cows placed into 1 of 4 mutually exclusive categories of hoof …

Assessment Of Lameness Prevalence And Associated Risk Factors In Dairy Herds In England And Wales, Z. E. Barker, K. A. Leach, H. R. Whay, N. J. Bell, D. C. J. Main

Farm Animal Welfare Collection

Visits were made to 205 dairy farms in England and Wales between October 2006 and May 2007 by 1 or more of 4 researchers. At each visit, all milking cows were locomotion scored (lameness scored) using a 4-point scale (0 = sound locomotion, 1 = imperfect locomotion, 2 = lame, 3 = severely lame). The mean prevalence of lameness (scores 2 and 3) across the study farms was 36.8% (range = 0–79.2%). On each farm, the presence within the housing and grazing environments of commonly reported risks for increased lameness was recorded. Each farmer was interviewed to gauge the ability …

A Survey Of The Management And Development Of Captive African Elephant (Loxodonta Africana) Calves: Birth To Three Months Of Age, Nicole L. Kowalski, Robert H.I. Dale, Christa L. H. Mazur

Scholarship and Professional Work - LAS

We used four surveys to collect information about the birth, physical growth, and behavioral development of 12 African elephant calves born in captivity. The management of the birth process and neonatal care involved a variety of standard procedures. All of the calves were born at night, between 7PM and 7AM. The calves showed a systematic progression in behavioral and physical development, attaining developmental milestones at least a quickly as calves in situ. This study emphasized birth-related events, changes in the ways that calves used their trunks, first instances of behaviors, and interactions of the calves with other, usually adult, elephants. …

Identifying Alternative Waste Conversion Technologies For Use At California Polytechnic State University San Luis Obispo, Matthew R. Bono

BioResource and Agricultural Engineering

This project was undertaken to identify and study alternative technologies for converting waste streams available on the Cal Poly San Luis Obispo campus into energy. As a large campus on the Central Coast of California Cal Poly not only produces lots of waste, but has limited options for its disposal. Furthermore, the campus is in the midst of an on-going green initiative, and more efficient use of its waste products would be a welcome development for the entire campus community. This report gathers information on waste streams originating at Cal Poly and information about waste to energy conversion technologies. The …

Winter Field Report, December 2009 To February 2010, W. Ross Silcock

Nebraska Bird Review

This was a long, cold winter, but effects on birds were not particularly noticeable. Perhaps the relative blandness of the reports reflected the "normal" behavior of most birds when confronted with a cold winter and the seriousness of survival: birds were in places they should have been. Carolina Wrens may have been hit (more on that in the Spring Report), but a few species were present in higher numbers than might have been expected. Rusty and Red-winged Blackbirds and Brown-headed Cowbird were notable for higher winter numbers, as were Snow Buntings. Even more so, there were lots of Fox Sparrows, …

Observations Of Piping Plovers (Charadrius Melodus) Color Banded In Nebraska And Re-Sighted On The United States Gulf Coast, Mary Bomberger Brown, Joel G. Jorgensen

Nebraska Bird Review

Threatened and endangered migratory birds present a challenge to conservation efforts because they use different habitats during different times of the year. As a result, successful efforts in one part of their range may be nullified by negative events taking place in other parts of their range. In many cases, information that links individual birds or populations to specific breeding, non-breeding, and migratory areas across the species' range is not available. Without these links, it can be difficult to coordinate conservation efforts across the species' range, and species recovery efforts may be less effective. The observation of uniquely marked individuals …

2009–2010 Christmas Bird Counts

Nebraska Bird Review

Fourteen Christmas Bird Counts were held in Nebraska in the 2009–2010 season. The Ames count was cancelled due to weather, the Beaver Valley count returned after a year's absence, and the North Platte count was reinstated after not being officially run since the 1985–86 season. Although the average high and low temperatures were not exceptional, heavy snow cover affected most, if not all, of the counts. Roads were closed due to snow drifts, open water was limited, and at least three counts had to be rescheduled. The total number of species (116) was the lowest since 103 in 1997.

Conserving Migratory Land Birds In The New World: Do We Know Enough?, John Faaborg, Richard T. Holmes, Angela D. Anders, Keith L. Bildstein

Dartmouth Scholarship

Migratory bird needs must be met during four phases of the year: breeding season, fall migration, wintering, and spring migration; thus, management may be needed during all four phases. The bulk of research and management has focused on the breeding season, although several issues remain unsettled, including the spatial extent of habitat influences on fitness and the importance of habitat on the breeding grounds used after breeding. Although detailed investigations have shed light on the ecology and population dynamics of a few avian species, knowledge is sketchy for most species. Replication of comprehensive studies is needed for multiple species across …

Foraging-Related Activity Of Bald Eagles At A Washington Seabird Colony And Seal Rookery, James L. Hayward, Joseph G. Galusha, Shandelle M. Henson

Faculty Publications

From 1980 to 1998, Washington's Bald Eagle (Haliaeetus leucocephalus) population increased at an annual rate of 10. Over the same time period, foraging activity of Bald Eagles at marine bird breeding colonies also increased. From 1993 to 2008, we observed foraging-related behavior of Bald Eagles on Violet Point, Protection Island. This island hosts more than 70 of the breeding seabirds in Washington's inner seaways and serves as an important rookery for harbor seals (Phoca vitulina). We found that (1) eagles landed more frequently in seal haul-out (beach) areas than in gull-nesting (non-beach) areas of Violet Point, and that subadult eagles …

Biogeography Of The American Pika (Ochotona Princeps) In Oregon And Southern Washington: Illuminating Genetic Relationships Among Disjunct Populations, George Washington Batten Iii

Dissertations and Theses

The American pika (Ochotona princeps) finds moderately warm temperatures (>25°C) lethally stressful, and at the end of the last Ice Age 10,000 years ago was forced to disperse to cooler, "sky island" mountaintops where they are almost exclusively found today. Thirty six subspecies are recognized, all established using morphological characters, and it is uncertain whether these subspecies' designations are corroborated by genetic analyses. This study elucidates three hypotheses regarding populations in Oregon and southern Washington: 1) O. p. fumosa constitutes a subspecies distinct form O. p. brunnescens, 2) the Columbia River constitutes a barrier to gene …

Age, Growth And Maturation Of Swordtip Squid (Photololigo Edulis) In The Southern East China Sea, Kae-Yih Wang, Kuo-Tien Lee, Cheng-Hsin Liao

Journal of Marine Science and Technology–Taiwan

The reproductive biology, and age and growth of the swordtip squid (Photololigo edulis) in the East China Sea were examined based on the growth ring of statoliths from 1797 specimens during the period of November 2002 to November 2004. The maximum age observed was 261 days in female and 253 days in male, an evidence showing that swordtip squid has a longevity of about 9 months in both sexes. Growth in mantle length (ML) and body weight (BW) in both sexes was best described by the exponential model. There was significantly difference in somatic or statolith growth between the sexes. …

Passive Immunity To White Spot Syndrome Virus (Wssv) In Penaeus Monodon Treated With Monoclonal Antibodies Of The Heterologously Produced Vp28 Viral Envelope Protein, Jyh-Yih Chen, Kumarasamy Anbarasu, Chin-Yu Chen, Ying-Chuan Lee, Fan-Hua Nan, Ching-Ming Kuo

Journal of Marine Science and Technology–Taiwan

White spot syndrome virus (WSSV) is a highly pathogenic and prevalent virus affecting shrimp culture worldwide including Taiwan. In the present study, the viral envelope protein, VP28, gene of the WSSV was cloned into a pET28a expression vector. VP28 was expressed as a protein with a 6-histidine tag in Escherichia coli and purified by a Ni-NTA column. Antiserum was raised against this recombinant VP28 protein in BALB/C mice, and it recognized the VP28 protein in purified virions and recombinant proteins. The antiserum was mixed with arginine (100 ppm), lysine (168 ppm), and phenylalanine (88 ppm), and the titer of the …

Antioxidant And Immune-Stimulating Activities Of Hot-Water Extract From Seaweed Sargassum Hemiphyllum, Pai-An Hwang, Chwen-Herng Wu, Shu-Yun Gau, Shih-Yung Chien, Deng-Fwu Hwang

Journal of Marine Science and Technology–Taiwan

The hot-water extract of seaweed Sargassum hemiphyllum was evaluated antioxidant activity by using four different methods, including DPPH free radicals scavenging activity, Fe+2 chelating activity, superoxide anion radical scavenging activity and reducing power, and the immune-stimulating activity by using HB4C5 cells and J774.1 cells. It was found that the antioxidant activity was increasing in correlating with the concentration below 3.5 mg/ml. The HB4C5 cells showed the maximum relative activities of cell proliferation (174%) and IgM secretion (132%) at 120 µg/ml of hot-water extract. Overheating slightly reduced the immune-stimulating activity of hot-water extract. At 80 µg/ml, J774.1 cells showed the maximum …

Initial Findings On Visual Acuity Thresholds In An African Elephant (Loxodonta Africana), Melissa R. Shyan-Norwalt, Jeff Peterson, Barbara Milankow King, Timothy E. Staggs, Robert H.I. Dale

Scholarship and Professional Work - LAS

There are only a few published examinations of elephant visual acuity. All involved Asian elephants (Elephas maximus) and found visual acuity to be between 8′ and 11′ of arc for a stimulus near the tip of the trunk, equivalent to a 0.50 cm gap, at a distance of about 2 m from the eyes. We predicted that African elephants (Loxodonta africana) would have similarly high visual acuity, necessary to facilitate eye-trunk coordination for feeding, drinking and social interactions. When tested on a discrimination task using Landolt-C stimuli, one African elephant cow demonstrated a visual acuity of …

Trait Selection And Welfare Of Genetically Engineered Animals In Agriculture, Michael Greger

Genetics Collection

The release of the Final Guidance from the US Food and Drug Administration on the commercialization of genetically engineered animals has sparked renewed discussion over the ethical, consumer, and regulatory implications of transgenesis in animal agriculture. Animal welfare critiques have focused on unexpected phenotypic effects in animals used in transgenic research, rather than on the health and welfare implications of the intended productivity enhancement. Unless breeding goals are redefined to reflect social concerns, the occurrence and magnitude of undesirable side effects may increase and consumer confidence in the nascent technology may be undermined.
