  1. Effect of breed and lithium chloride dose on the conditioned aversion to olive tree leaves (Olea europaea L.) of sheep

    Contributor(s):: Manuelian, Carmen L., Albanell, Elena, Rovai, Maristela, Salama, Ahmed A. K., Caja, Gerardo

    Grazing maybe an efficient tool for controlling weed cover in olive groves. However, olive leaves are very palatable for sheep, which damages the trees and compromised the later olive production. Lithium chloride (LiCl) is an effective agent for creating food aversion in ruminants through the...

  2. A modeling approach for estimating seasonal dietary preferences of goats in a Mediterranean Quercus frainetto–Juniperus oxycedrus woodland

    | Contributor(s):: Manousidis, T., Malesios, C., Kyriazopoulos, A. P., Parissi, Z. M., Abraham, E. M., Abas, Z.

    Goats are characterized as selective feeders due to their specific feeding behavior, thus the study of their seasonal preferences in a Mediterranean oak-juniper ecosystem is of great interest. The current research was conducted in an open oak forest in Megalo Dereio region, northeastern Greece...

  3. The use of a shaded area during farrowing and lactation in sows kept outdoors

    | Contributor(s):: Schild, Sarah-Lina A., Rangstrup-Christensen, Lena, Bonde, Marianne, Pedersen, Lene J.

    The hut temperature in outdoor pig production during summer can exceed the upper critical temperature of lactating sows. Therefore, sows may experience hyperthermia, a condition which has several adverse consequences for the welfare of both sow and piglets. Thus, the aim of the current study was...

  4. Avian reactions towards human approaches in different urban greenery structures in Nanaimo

    | Contributor(s):: Campbell, M.

    Urban green spaces are vital for human quality of life and urban avian ecology. In consequence, these areas attract cutting edge research on human/animal relations and the human roles in avian foraging grounds. However, few studies of bird reactions to human presence have included bird adaptation...

  5. Silvopastoral systems for sustainable animal production and the role of animal welfare

    | Contributor(s):: Broom, D.

  6. Methodology for estimating deer browsing impact

    | Contributor(s):: Pierson, Timothy G., deCalesta, David S.

  7. Regulation of tree squirrel populations with immunocontraception: a fox squirrel example

    | Contributor(s):: Krause, Sara K., Kelt, Douglas A., Van Vuren, Dirk H., Gionfriddo, James P.

  8. 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

  9. 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...

  10. Reaching new heights: the effect of an environmentally enhanced outdoor enclosure on Gibbons in a zoo setting

    | Contributor(s):: Anderson, M. R.

    Gibbons have adapted to live in the canopy layer of the rainforest. Gibbons in the wild predominantly spend their time high in the trees resting, traveling, and foraging for food. Comparatively, gibbons in the zoo often rest and search for their food terrestrially. The purpose of this study was...

  11. Urban gray squirrel damage and population management: A case history

    | Contributor(s):: J. Hadidian, D. Manski, V. Flyger, C. Cox, G. Hodge

    Lafayette Park, a 3.0 hectare national park located across the street from the White House in Washington D.C., has had a gray squirrel (Sciurus carolinensis) density as high as 50 animals/hectare. In recent years this large population caused significant damage to mature trees and other...

  12. Effects of grackle damage control techniques in citrus on nesting success of non-target species

    | Contributor(s):: John H. Rappole, Wan R. Tipton, Arlo H. Kane, Rafael H. Flores

    Several techniques were tested to reduce the damage caused by great-tailed grackles to citrus in the lower Rio Grande Valley of southern Texas: monofilament line, eyespot balloons, pyrotechnics, and grackle nest removal. Ten species were found nesting in the treated groves, but only the mourning...

  13. Bird consumption of sweet and tart cherries

    | Contributor(s):: Lindell, C. A., Eaton, R. A., Lizotte, E. M., Rothwell, N. L.

  14. EU DAISIE research project: wanted - death penalty to keep native species competitive?

    | Contributor(s):: Zisenis, M.

  15. Group sizes and resting locations of free range pigs when grazing in a natural environment

    | Contributor(s):: Rodriguez-Estevez, V., Sanchez-Rodriguez, M., Gomez-Castro, A. G., Edwards, S. A.

    A herd of 86 Iberian pigs aged 13+or-0.5 months and with an average live weight of 110+or-1.3 kg at the start of the study was followed to monitor their social organisation (spontaneous group size: GS) and resting preferences when free ranging on natural pastures in a dehesa of evergreen oaks...

  16. Preferences of Orange-winged Amazon parrots ( Amazona amazonica ) for cage enrichment devices

    | Contributor(s):: Kim, L. C., Garner, J. P., Millam, J. R.

    Cage enrichment devices (ED), frequently termed cage "toys", are often provided to captive parrots as a means of promoting a behaviorally stimulating environment, but it is not clear whether particular properties of EDs are more effective than others in eliciting engagement with them. We tested...

  17. Fear assessment in pigs exposed to a novel object test

    | Contributor(s):: Dalmau, A., Fabrega, E., Velarde, A.

    The experiment aimed to study approach and locomotive behaviour as indicators of fear in a novel object test carried out in pigs. Thirty post-weaning (30 kg) and 30 finishing (90 kg) pigs were exposed to visual, auditory and olfactory novel stimuli during 2 different experiments. The facilities...

  18. Grazing distribution of sheep and kangaroos in a semi-arid woodland

    | Contributor(s):: Terpstra, J. W., Wilson, A. D.

    The grazing distribution of sheep and kangaroos was studied within a semi-arid mulga [Acacia aneura] woodland in the rangelands of Australia. Observations were made on 3 occasions over 6 months on 6 plots of a grazing trial. Three of the plots were grazed by sheep and kangaroos, and 3 by sheep...

  19. Influence of secondary compound complementarity and species diversity on consumption of Mediterranean shrubs by sheep

    | Contributor(s):: Rogosic, J., Estell, R. E., Skobic, D., Stanic, S.

    Generalist herbivores foraging in chemically diverse grazing ecosystems like the Mediterranean maquis increase intake on mixed diets, suggesting they are more able to meet nutritional needs and avoid toxicosis. Thus, our objectives were to determine how shrub species diversity and complementary...

  20. Diet selection in dairy goats grazing woody Mediterranean rangeland

    | Contributor(s):: Perevolotsky, A., Landau, S., Kababia, D., Ungar, E. D.

    Species selection, diet quality and voluntary intake were studied in Anglo-Nubian x Damascus dairy goats grazing woody Mediterranean rangeland in the Jerusalem Hills, Israel. Measurements comprised direct observation of grazing behaviour, with the recording of all species encountered along the...
