  1. Targeted grazing of milk thistle (Silybum marianum) and Syrian thistle (Notobasis syriaca) by goats: Preference following preconditioning, generational transfer, and toxicity

    Contributor(s):: Arviv, A., Muklada, H., Kigel, J., Voet, H., Glasser, T., Dvash, L., Ungar, E. D., Landau, S. Y.

    Nitrophilic thistles such as milk thistle (Sylibum marianum) and Syrian thistle (Notobasis syriaca) encroach rangeland areas where animals gather and defecate, in particular around watering and feeding points. High densities of milk and Syrian thistles (MST) diminish forage yields and detract...

  2. An evaluation of two traps and sets for trapping the plains pocket gopher

    Contributor(s):: Vantassel, Stephen M., Tyre, Andrew J., Hygnstrom, Scott E.

  4. Straying Wild Horses and the Range Landowner: The Search for Peaceful Coexistence

    Contributor(s):: Alfred W. Buckley, William W. Buckley

    In 1971 Congress passed Public Law 92-195, the Wild Free-Roaming Horses and -Burros Act,' to preserve a vanishing symbol of American pioneer heritage.' Before this statute was enacted, wild horses and burros were in danger of extinction. Today the success of the Act has...

  5. Revisiting distinctions between ranching and pastoralism a matter of interspecies relations between livestock, people, and predators

    Contributor(s):: LaRocque, Olivier

  6. Environmental duty of care: from ethical principle towards a code of practice for the grazing industry in Queensland (Australia)

    Contributor(s):: Greiner, R.

    Among the options of government for reducing negative environmental externalities from agriculture is the institution of a polluter statutory liability. An environmental duty of care imposes a statutory liability on agents who interact with the environment to avoid causing environmental harm....

  7. Management, health, and abnormal behaviors of horses: a survey in small equestrian centers in Brazil

    Contributor(s):: Leme, D. P., Parsekian, A. B. H., Kanaan, V., Hotzel, M. J.

    Care conditions of horses housed in small equestrian establishments and the occurrence of health and behavioral problems were assessed in 197 animals. Based on questionnaires and direct observations of the animals, it was noted that 8% of all animals were fed exclusively on pasture, whereas 92%...

  8. The human-animal interface of domestic livestock management and production and its relationship to brucellosis in the country of Georgia 2010: a rapid assessment analysis

    Contributor(s):: Havas, K. A., Ramishvili, M., Navdarashvili, A., Imnadze, P., Salman, M.

  9. Behavioural responses of cattle to shared foraging with wild herbivores in an East African rangeland

    Contributor(s):: Odadi, W. O., Okeyo-Owuor, J. B., Young, T. P.

    We assessed whether prior foraging by wild herbivores affected foraging behaviour of cattle in Laikipia rangeland, Kenya, during February 2001, August 2001 and February 2002. The study compared cattle bite rate, step rate and bites per step in plots exclusively accessible to cattle and those...

  10. Feeding behaviour of sheep on shrubs in response to contrasting herbaceous cover in rangelands dominated by Cytisus scoparius L

    Contributor(s):: Pontes, L. da S., Agreil, C., Magda, D., Gleizes, B., Fritz, H.

    The foraging responses of ewes faced with a diversity of feed items and their effects on broom (Cytisus scoparius L.) consumption were examined. The experiment was conducted on a farm in the autumn with ewes (n=33) grazing three small paddocks (0.44 ha on average, for at least 10 days each)...

  11. Cattle grazing behavior with season-long free-choice access to four forage types

    Contributor(s):: Fehmi, J. S., Karn, J. F., Ries, R. E., Hendrickson, J. R., Hanson, J. D.

    This experiment investigated how season-long, free-choice grazing affected weekly cattle grazing behaviour and resource use. Our objectives were to determine if known forage preferences change through the season, if feedbacks from previous grazing intensity affect current use, and if resources...

  12. Landscape nutritional patterns and cattle distribution in rangeland pastures

    Contributor(s):: Ganskopp, D. C., Bohnert, D. W.

    On rangelands, uneven or unmanaged livestock distribution can adversely affect plant community composition, riparian function, or displace wildlife. These issues have historic precedents and are still a challenge for those managing rangelands. A thorough understanding of the mechanisms governing...

  13. Least-effort pathways: a GIS analysis of livestock trails in rugged terrain

    Contributor(s):: Ganskopp, D., Cruz, R., Johnson, D. E.

    Cattle trails were mapped in three 800+ ha pastures with global positioning units. A geographic information system (GIS) helped quantify characteristics of trails and the landscape and was used to plot least-effort pathways between water sources and distant points on selected trails in the...

  14. Winter range use by cattle of different ages in southwestern Montana

    Contributor(s):: Beaver, J. M., Olson, B. E.

    During two winters (1993/94 and 1994/95), the use of winter range by young (3-year-old) cattle that had no experience on winter range was compared with mature (7- to 8-year-old) cattle that had experience on winter range. Ten 3-year-old cows were alternated weekly with ten 7- to 8-year-old cows...

  15. A note on diet selection by goats on a semi-arid temperate rangeland throughout the year

    Contributor(s):: Ricardi, C., Shimada, A.

    A descriptive study and an experiment assessed the selectivity of goats on restricted grazing on a semi-arid temperate rangeland. In 1987 a mixed-breed herd was monitored once a week for 16 consecutive weeks from April to July. In April, July and October of 1989, and January of 1990, the same...

  16. Conditioning ewes and lambs to increase consumption of spotted knapweed

    Contributor(s):: Whitney, T. R., Olson, B. E.

    Spotted knapweed (Centaurea maculosa Lam.) is an invasive plant that alters species composition and grazing value of rangelands in the northwestern United States. The spread of invasive plants may be reduced by using livestock as a biological control. We determined if mature ewes and their lambs...

  17. Differences among beef sire breeds and relationships between terrain use and performance when daughters graze foothill rangelands as cows

    Contributor(s):: VanWagoner, H. C., Bailey, D. W., Kress, D. D., Anderson, D. C., Davis, K. C.

    A study was conducted on foothill rangeland to determine if breed of sire affected grazing distribution patterns and to evaluate relationships between individual grazing patterns and performance of beef cows. Angus (AN), Charolais (CH), Piedmontese (PI), and Salers (SA) sires were mated to dams...

  18. Evaluation of a positive conditioning technique for influencing big sagebrush ( Artemisia tridentata subspp. wyomingensis ) consumption by goats

    Contributor(s):: Richman, L. M., Johnson, D. E., Angell, R. F.

    Diets of Angora goats positively conditioned to eat big sagebrush (Artemisia tridentata subspp. wyomingensis) were compared with controls to assess the effects of positive conditioning. Goats were conditioned by including increasing amounts of sagebrush in the daily diet, to a maximum of 25% by...

  19. Extensive ranging by sheep released onto an unfamiliar range

    Contributor(s):: Warren, J. T., Mysterud, I.

    During radio telemetry studies of domestic sheep on open forested ranges in Hedmark County in southeastern Norway, several examples of extremely extensive ranging, either by individual sheep introduced into established flocks or by flocks turned onto unfamiliar ranges, have been recorded. In one...

  20. Free-ranging cattle water consumption in southcentral New Mexico

    Contributor(s):: Rouda, R. R., Anderson, D. M., Wallace, J. D., Murray, L. W.

    Water-drinking behaviour of 67 beef cattle grazing on rangelands (vegetation included Hilaria mutica, Scleropogon brevifolius, Sporobolus airoides, Sporobolus contractus, Sporobolus flexuosus, Prosopis juliflora var. glandulosa, Psorothamnus scoparius and Yucca elata) without or with a protein...
