  1. Daytime summer access to pasture vs. free-stall barn in dairy cows with year-long outdoor experience: A case study

    Contributor(s):: Shepley, Elise, Bergeron, Reneé, Vasseur, Elsa

    With its documented health and behavioural benefits, one would expect dairy cows to have near unconditional preference for pasture. However, dairy cow preference is multifaceted with numerous factors contributing to the choices and or actions of the cow. Experience is one such factor that may...

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

    Contributor(s):: Idibu, Joachine, Kabi, Fred, Mpairwe, Denis

    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...

  3. 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...

  4. 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...

  5. Mother-young behaviours at lambing in grazing ewes: effects of lamb sex and food restriction in pregnancy

    Contributor(s):: Freitas-De-Melo, A., Ungerfeld, R., Hotzel, M. J., Abud, M. J., Alvarez-Oxiley, A., Orihuela, A., Damian, J. P., Perez-Clariget, R.

    This study investigated whether the level of pasture allowance from before conception until late pregnancy affects ewe-lamb behaviours at birth, and if those behaviours differ according to the sex of the lambs. We performed two experiments, in which 96 ewes were assigned to one of two nutritional...

  6. Daily grazing time of dairy cows is recorded accurately using the Lifecorder Plus device

    Contributor(s):: Delagarde, R., Lamberton, P.

    Accurate estimation of daily grazing time and nycthemeral grazing pattern in ruminant nutrition research may result in a better understanding of sward-animal interactions and of the behavioural constraints affecting daily intake at pasture. Portable devices which automatically record grazing...

  7. Oral behaviors of beef steers in pen and pasture environments

    Contributor(s):: Ishiwata, T., Uetake, K., Kilgour, R. J., Eguchi, Y., Tanaka, T.

    This study observed the behavioral characteristics of 122 steers in eight pens and 1,136 steers at six pastures. Nonhuman animals kept in pens performed less nutritive oral behaviors and more nonnutritive oral behaviors than animals kept at pasture. Although these could not be described as...

  8. Concepts of animal health and welfare in organic livestock systems

    Contributor(s):: Vaarst, M., Alroe, H. F.

  9. Global Animal Partnership's 5-Step<sup>TM</sup> Animal Welfare Rating Standards: a welfare-labelling scheme that allows for continuous improvement

    Contributor(s):: Duncan, I. J. H., Park, M., Malleau, A. E.

  10. 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...

  11. How do horses appraise humans' actions? A brief note over a practical way to assess stimulus perception

    Contributor(s):: Baragli, P., Gazzano, A., Martelli, F., Sighieri, C.

    Heart rate (HR) is considered to be an effective tool for assessing animals' emotional response to a stimulus. We investigated changes in HR during a series of handling procedures (grooming test) in horses that had different experiences of human interaction. We used four groups of horses: grazing...

  12. Animal agriculture: symbiosis, culture, or ethical conflict? (Animals and their welfare)

    Contributor(s):: Lund, V., Olsson, I. A. S.

    Several writers on animal ethics defend the abolition of most or all animal agriculture which they consider an unethical exploitation of sentient non-human animals. However, animal agriculture can also be seen as a co-evolution over thousands of years, that has affected biology and behaviour on...

  13. Least harm: a defense of vegetarianism from Steven Davis's omnivorous proposal

    Contributor(s):: Matheny, G.

    This paper analyses the article of Steven Davis entitled, "Least Harm," which argues that the number of animals killed in ruminant-pasture production is less than the number of animals killed in crop production. Davis concludes the adoption of an omnivorous diet would cause less harm than the...

  14. The design and implementation of sustainable plant diversity conservation program for alpine meadows and pastures

    Contributor(s):: Baumgartner, J., Hartmann, J.

    The paper describes the design and implementation of a plant biodiversity conservation programme that was developed under funding and time constraints for diverse ecological, social, and institutional environments. The biodiversity programme for alpine meadows and pastures in the Canton of the...

  15. Human behavior influences infectious disease emergence at the human-animal interface

    Contributor(s):: Alexander, K. A., McNutt, J. W.

    Although human behavior is frequently cited as a factor influencing the emergence of disease at the human-animal interface, few empirical studies have demonstrated this relationship. We compare humans and their domestic animals living in close proximity to populations of the endangered African...

  16. Activity bout criteria for grazing dairy cows

    Contributor(s):: Rook, A. J., Huckle, C. A.

    Data on the eating, ruminating and idling activity of grazing dairy cows recorded to a resolution of 1 min were used to study the choice of activity bout criteria and the implications of this choice. An inter-bout length of 5 min was found to be suitable for all 3 activity categories across a...

  17. An automatic system to record foraging behaviour in free-ranging ruminants

    Contributor(s):: Rutter, S. M., Champion, R. A., Penning, P. D.

    Precise measurements of grazing behaviour are required to develop an understanding of the factors affecting the foraging behaviour of free-ranging domestic ruminants. An automatic, microcomputer-based system for the digital recording of the jaw movements of free-ranging cattle and sheep is...

  18. Dietary preference of dairy heifers grazing ryegrass and white clover, with and without an anti-bloat treatment

    Contributor(s):: Rutter, S. M., Orr, R. J., Yarrow, N. H., Champion, R. A.

    The effect of an antibloat treatment on the dietary preference of nonpregnant Holstein x Friesian heifers for ryegrass and white clover was studied. Eight groups of two heifers grazed 0.51 ha plots containing adjacent monocultures of grass alongside clover with either 25 or 75% clover (by ground...

  19. Diurnal patterns of intake rate by sheep grazing monocultures of ryegrass or white clover

    Contributor(s):: Orr, R. J., Penning, P. D., Harvey, A., Champion, R. A.

    The effects of time of day on the ingestive behaviour of groups of 5 sheep grazing monocultures of ryegrass (Lolium perenne cv. Parcour) or white clover (Trifolium repens cv. Kent Wild White), were measured over periods of 1 h starting at 07.30, 11.30, 15.30 and 19.30 h in August 1993. Grazing...

  20. Effect of dairy cattle husbandry on behavioural patterns of red deer ( Cervus elaphus ) in the Italian Alps

    Contributor(s):: Mattiello, S., Redaelli, W., Carenzi, C., Crimella, C.

    The present study aimed to investigate in the field the effect of the presence of cattle on red deer behavioural patterns, in order to provide information that could be used to improve land management strategies. The research was carried out in a summer range at 1500 m a.s.l. in the Italian...
