  1. Soil quality manipulation to reduce bird presence at airports

    Contributor(s):: Johnston, Theresa K., Branham, Bruce, Brawn, Jeffrey

  2. Olfactory discrimination and generalization of ammonium nitrate and structurally related odorants in Labrador retrievers

    Contributor(s):: Lazarowski, L., Foster, M. L., Gruen, M. E., Sherman, B. L., Fish, R. E., Milgram, N. W., Dorman, D. C.

    A critical aspect of canine explosive detection involves the animal's ability respond to novel, untrained odors based on prior experience with training odors. In the current study, adult Labrador retrievers ( N=15) were initially trained to discriminate between a rewarded odor (vanillin) and an...

  3. Canine digging behavior and archaelogical implications

    Contributor(s):: Jeske, Robert J.

  4. Around cats

    Contributor(s):: Goldstein, E. J. C., Greene, C. E., Schlossberg, D.

    This chapter focuses on diseases transmitted from cats to humans. The diseases transmitted by inhalation (bordetellosis, plague and Q fever), vectors (ehrlichiosis, anaplasmosis, cat scratch disease, bacillary angiomatosis, flea-borne spotted fever, murine typhus and leishmaniasis), faecal-oral...

  6. Influence of environmental conditions and facility on faecal glucocorticoid concentrations in captive pygmy rabbits ( Brachylagus idahoensis)

    Contributor(s):: Scarlata, C. D., Elias, B. A., Godwin, J. R., Powell, R. A., Shepherdson, D., Shipley, L. A., Brown, J. L.

  7. Defaecation and urination behaviour in beef cattle grazing semi-natural grassland

    Contributor(s):: Orr, R. J., Griffith, B. A., Champion, R. A., Cook, J. E.

  8. Welfare outcomes assessment in laying hen farm assurance schemes

    Contributor(s):: Main, D. C. J., Mullan, S., Atkinson, C., Bond, A., Cooper, M., Fraser, A., Browne, W. J.

  9. Farmers' perceptions of livestock, agriculture, and natural resources in the rural Ethiopian highlands

    Contributor(s):: Tschopp, R., Aseffa, A., Schelling, E., Zinsstag, J.

    Increasing human and livestock populations in Ethiopia are leading to a growing demand for food and feed. Cereal cropping is highly prioritized at the cost of the livestock subsector and the environment. Grazing land is decreasing, leading to overstocking and overgrazing of pastures, thus fueling...

  10. Critical impact assessment of organic agriculture

    Contributor(s):: Xie, Biao, Wang, XiaoRong, Ding, ZhuHong, Yang, YaPing

    Based on its production guideline, organic agriculture has set for itself the goals of minimizing all forms of pollution and maintaining sustainability of the farming system. By striving for these goals, organic farming meets the demands of an increasing number of consumers who are critical of...

  11. Geophagia in horses: a short note on 13 cases

    Contributor(s):: McGreevy, P. D., Hawson, L. A., Habermann, T. C., Cattle, S. R.

    Recorded in several species including humans, geophagia or soil eating has been observed in both wild and domesticated horses and has generally been regarded as an indication of nutritional deficiency or "boredom". Studies of soils consumed by different species have led to several theories as to...

  12. The risk factors affecting the development of gentle and severe feather pecking in loose housed laying hens

    Contributor(s):: Lambton, S. L., Knowles, T. G., Yorke, C., Nicol, C. J.

    Injurious pecking remains one of the biggest problems challenging free range egg producers, with both economic implications for the farmer and welfare implications for the birds. The most widespread form of injurious pecking is feather pecking, the most damaging form of which is severe feather...

  13. Oral/nasal/facial and other behaviors of sows kept individually outdoors on pasture, soil or indoors in gestation crates

    Contributor(s):: Dailey, J. W., McGlone, J. J.

    PIC Camborough-15 sows were housed either on pasture (n=8), on soil (n=8) or in gestation crates (n=16). All were fed 2.0 kg of fortified sorghum-soybean diet each day in pellet form, except half of the crated sows which were fed meal. The occurrences of standing, lying, sitting, feeding,...

  14. Amounts of pesticides reaching target pests: environmental impacts and ethics

    Contributor(s):: Pimentel, D.

    An examination of published work on arthropod pests, pathogens and weeds of crops indicated that less than 0.1% of pesticides applied for pest control reach their target pests. Thus, more than 99.9% of pesticides used move into the environment where they adversely affect public health and...

  15. Are intensive agricultural practices environmentally and ethically sound?

    Contributor(s):: Lal, R., Miller, F. P., Logan, T. J.

    Improper soil management and indiscriminate use of chemicals have contributed to some severe global environmental issues, e.g., volatilization losses and contamination of natural waters by sediments and agricultural fertilizers and pesticides. The increasing substitution of energy for labour and...

  16. Biofuels: efficiency, ethics, and limits to human appropriation of ecosystem services

    Contributor(s):: Gomiero, T., Paoletti, M. G., Pimentel, D.

    Biofuels have lately been indicated as a promising source of cheap and sustainable energy. In this paper we argue that some important ethical and environmental issues have also to be addressed: (1) the conflict between biofuels production and global food security, particularly in developing...

  17. Locus of control and farmer orientation: effects on conservation adoption

    Contributor(s):: McNairn, H. E., Mitchell, B.

    Farmers in a southwestern Ontario watershed were surveyed to determine factors influencing their attitudes towards adoption of soil conservation practices. The majority of farmers in the watershed were internally motivated, which indicates that they believe that their own actions determine their...

  18. Nitrogen turnover on organic and conventional mixed farms

    Contributor(s):: Halberg, N., Kristensen, E. S., Kristensen, I. S.

    Separate assessment of crop fertilization or feeding practices inadequately describes nitrogen (N) loss from mixed dairy farms because of: (1) interaction between animal and crop production and between the production system and the manager; and (2) uncertainties of herd N production and crop N...

  19. To everything there is a season: Reinvest in Minnesota (RIM) and soil conservation

    Contributor(s):: Frey, R. M.

    The paper explores the severity of the problem of soil erosion and a variety of approaches to the problem. The typology of approaches includes doing nothing, individual party litigation, the state's invocation of public trust doctrine, and the state's exercise of its police power. The Reinvest in...
