  1. Equine ingestion of haylage harvested at different plant maturity stages

    Contributor(s):: Müller, Cecilia E.

    The influence of plant maturity at harvest of haylage on equine ingestion times and ingestive behaviour was studied. Haylage was harvested at three different occasions: June, July and August, from the primary growth of the same grass-dominated sward. Twelve adult horses of European warmblood type...

  2. Human-Managed vs. Natural Grazing Systems: Exploring Effects of Livestock and Wildlife Grazing at Multiple Scales

    Contributor(s):: Megan Esther McSherry

    Grazing by large herbivores is the most prevalent land use on grassland ecosystems, which cover greater than 40% of the earth's land surface and provide critical ecological and economic benefits. As such, understanding how grazing impacts different aspects of the ecosystem is of especially...

  3. Grass management regimes affect grasshopper availability and subsequently American crow activity at airports

    Contributor(s):: Kennedy, Laura A., Otter, Ken A.

  4. Modeling waterfowl damage to crops surrounding the Quill lakes in Saskatchewan

    Contributor(s):: Callaghan, Carolyn J., Daneshfar, Bahram, Thompson, Donald J.

  5. Response of a small population of greater sage-grouse to tree removal: implications of limiting factors

    Contributor(s):: Frey, S. Nicole, Curtis, Rachel, Heaton, Kevin

  6. Effects of site characteristics, pinyon-juniper management, and precipitation on habitat quality for mule deer in New Mexico

    Contributor(s):: Bender, Louis C., Boren, Jon C., Halbritter, Heather, Cox, Shad

  7. Rodent population management at Kansas City International Airport

    Contributor(s):: Witmer, G. W.

  8. Preference of white-tailed deer for corn hybrids and agricultural husbandry practices during the growing season

    Contributor(s):: Delger, J. A., Monteith, K. L., Schmitz, L. E., Jenks, J. A.

  9. Behavioural response of pure Ankole and crossbred (Ankole * Holstein) cows to seasonal pasture variations in south-western Uganda

    Contributor(s):: Idibu, J., Kabi, F., Mpairwe, D.

    This study evaluated the effects of season and pasture species on variations in sward composition, pasture quantity (plant-height and biomass) and quality [crude protein (CP), neutral detergent fibre (NDF) and in vitro organic matter digestibility (IVOMD)]. Behavioural responses of a group of 10...

  10. Degree of synchrony based on individual observations underlines the importance of concurrent access to enrichment materials in finishing pigs

    Contributor(s):: Zwicker, B., Weber, R., Wechsler, B., Gygax, L.

    Pigs are sociable animals with a strong motivation to explore and forage, and it has been stated that they have a strong motivation to do so synchronously. We examined the synchrony of exploration in groups of finishing pigs when enrichment materials were offered. We used a novel measure of...

  11. Dustbathing, pecking and scratching behaviours of laying hens in furnished cages are enhanced by the presence of rubber mats and litter distribution

    Contributor(s):: Guinebretiere, M., Michel, V., Arnould, C.

    Furnished cages for laying hens exist in a wide variety of sizes and designs and should be equipped to allow hens to express some of their behavioural priorities. European Council Directive 1999/74/EC stipulates that litter must be provided for pecking and scratching but the type of litter and...

  12. Condensed tannins reduce browsing and increase grazing time of free-ranging goats in semi-arid savannas

    Contributor(s):: Mkhize, N. R., Heitkonig, I. M. A., Scogings, P. F., Dziba, L. E., Prins, H. H. T., Boer, W. F. de

    Tannin concentrations fluctuate spatially and temporally within and among plant species, with consequences for forage quality of herbivores. The extent to which these fluctuations influence foraging activities of goats is not fully understood. While accounting for the effects of the time of the...

  13. Retracting inconclusive research: lessons from the Seralini GM maize feeding study

    Contributor(s):: Resnik, D. B.

    In September 2012, Gilles-Eric Seralini and seven coauthors published an article in Food and Chemical Toxicology claiming that rats fed Roundup-resistant genetically modified maize alone, genetically modified maize with Roundup, or Roundup for 2 years had a higher percentage of tumors and kidney...

  14. Effects of stage of gestation at mixing on aggression, injuries and stress in sows

    Contributor(s):: Stevens, B., Karlen, G. M., Morrison, R., Gonyou, H. W., Butler, K. L., Kerswell, K. J., Hemsworth, P. H.

    Confinement of breeding sows to stalls is a controversial welfare issue, and there is a worldwide move to house gestating sows in groups. We examined the effects of day of mixing following insemination on aggression, injuries and stress in sows. A total of 800 sows were used in this experiment...

  15. Density-dependent diet selection and body condition of cattle and horses in heterogeneous landscapes

    Contributor(s):: Cornelissen, P., Vulink, J. T.

    For some decades, grazing by cattle and horses is used as a management tool to achieve different nature management goals. For managers there are still questions to be answered about the effects of herbivore densities on their performance, vegetation development and biodiversity. This study...

  16. Behavioural assessment of dental pain in captive Malayan sun bears ( Helarctos malayanus)

    Contributor(s):: Fleming, M., Burn, C. C.

    Captive bears are prone to developing dental pathology for reasons including longevity in captivity, inappropriate diet, trauma, and stereotypical bar biting. If not detected, this can cause pain and suffering, with negative welfare consequences. As animals cannot verbally express feelings,...

  17. Behaviour and welfare of veal calves fed different amounts of solid feed supplemented to a milk replacer ration adjusted for similar growth

    Contributor(s):: Webb, L. E., Bokkers, E. A. M., Engel, B., Gerrits, W. J. J., Berends, H., Reenen, C. G. van

  18. Effects of grassland alteration from mowing and fire on bird activity at a Colorado airfield

    Contributor(s):: Carragher, K. A., Clawges, R. M., Bunn, R. L., Pigage, H. K., Pigage, J. C.

  19. A framework for the ethical analysis of novel foods: the ethical matrix

    Contributor(s):: Mepham, B.

    The paper addresses the issue of how in democratic societies a procedure might be formulated to facilitate ethical judgements on modern biotechnologies used in food production. A framework for rational ethical analysis, the Ethical Matrix, is proposed. The Matrix adapts the principles described...

  20. Coexistence of plants and coexistence of farmers: is an individual choice possible?

    Contributor(s):: Binimelis, R.

    The introduction of genetically modified organisms (GMOs) in Europe has been characterized by controversy. In 2002, the European Union introduced the concept of "coexistence" as a compromise solution that, through the establishment of science-based technical measures, should allow the market to...
