  1. The effect of a view to the surroundings and microclimate variables on use of a loafing area in housed dairy cattle

    Contributor(s):: Haskell, Marie J., Masłowska, Katarzyna, Bell, David J., Roberts, David J., Langford, Fritha M.

    There is concern that cows that are continuously housed year-round may lack the opportunity to express a full range of natural behaviour. Providing these cows with a loafing or exercise area may allow them the space to express a greater behavioural repertoire. Little is known about the factors...

  2. Cattle habitat selection and associated habitat characteristics under free-range grazing within heterogeneous Montane rangelands of Alberta

    Contributor(s):: Kaufmann, Jillian, Bork, Edward W., Blenis, Peter V., Alexander, Michael J.

    The integration of multiple uses on public rangeland requires reliable information on patterns of livestock use. We used GPS data and field plot utilization indices to examine cattle selection at the landscape and patch levels, respectively, within a heterogeneous Montane environment of SW...

  3. Can the location of cattle be managed using broadcast audio cues?

    Contributor(s):: Umstatter, Christina, Brocklehurst, Sarah, Ross, David W., Haskell, Marie J.

    Fences are crucial for successful grazing management of livestock. However, conventional fencing is expensive and lacks spatial flexibility. To date, this flexibility has been provided by electric fences, but these are not always efficient to erect and move and are not suitable for all locations....

  4. Behavioural mechanisms of intake rate by heifers grazing swards of contrasting structures

    Contributor(s):: Mezzalira, Jean Carlos, De Faccio Carvalho, Paulo César, Fonseca, Lidiane, Bremm, Carolina, Cangiano, Carlos, Gonda, Horacio Leandro, Laca, Emilio Andrés

    The relationship between herbage intake by herbivores and herbage available depends on the interaction between sward structure and animal behaviour. This relationship is a crucial component determining the stability, function and productivity of grazing systems. The present study aims at...

  5. Automatic registration of grazing behaviour in dairy cows using 3D activity loggers

    Contributor(s):: Nielsen, Per Peetz

    Automated systems for monitoring behaviour of cows within dairy production are increasing and developments in technology provide new opportunities in this area. This study aimed to validate the use of a 3D activity logger (HOBO® Pendant G Data Logger), that registers the cow's head positions...

  6. Training methods for introducing cows to a pasture-based automatic milking system

    Contributor(s):: Jago, J., Kerrisk, K.

    Training cows to use an automatic milking system (AMS) is an important process as this method of milking depends on cows voluntarily using the AMS. This study examined two levels of training before calving on the behaviour of cows and heifers in an extensive pasture-based AMS. Animals received...

  7. Grazing behavior of sheep at different stocking rates in the Inner Mongolian steppe, China

    Contributor(s):: Lin, Lijun, Dickhoefer, Uta, Müller, Katrin, Wurina,, Susenbeth, Andreas

    In free-ranging or grazing animals, physical activity can account for a substantial proportion of their total energy requirement with considerable consequences for animals at low production level. This study evaluated the effect of grazing intensity (GI) on behavior and walking distance of sheep...

  8. Foraging behaviour of beef heifers and ewes in natural grasslands with distinct proportions of tussocks

    Contributor(s):: Bremm, Carolina, Laca, Emilio Andrés, Fonseca, Lidiane, Mezzalira, Jean Carlos, Elejalde, Denise Adelaide Gomes, Gonda, Horacio Leandro, Carvalho, Paulo César de Faccio

    In natural grasslands, plant species preferred by grazing animals are intermixed with less preferred species. We hypothesise that increasing proportion of Eragrostis plana Nees tussocks, a non-preferred diet item in natural grassland, will constrain the accessibility of the preferred diet item...

  9. Eliminative behaviour of dairy cows at pasture

    Contributor(s):: Whistance, Lindsay Kay, Sinclair, Liam A., Arney, David Richard, Phillips, Clive Julian Christie

    Despite a strong avoidance of grazing near dung patches, cattle have traditionally been considered not to avoid bodily contact with faeces, regardless of any risk of disease. Little is understood of the behaviour of pasture-kept dairy cows at the time of defaecation and therefore, the eliminative...

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

    Contributor(s):: Orr, Robert J., Griffith, Bruce A., Champion, Robert A., Cook, James E.

    There is increasing global interest in the extent to which multi-species grasslands containing increased plant diversity compared with improved grasslands can also deliver higher resource protection. The objective of this experiment was to examine nutrient returns via faeces and urine by...

  11. Microhabitat selection of free-ranging beef cattle in south-boreal forest

    Contributor(s):: Spedener, Mélanie, Tofastrud, Morten, Devineau, Olivier, Zimmermann, Barbara

    Cattle released for summer grazing in south-boreal forest are free to select among a broad range of habitats. The goal of this study was to identify the factors influencing the microhabitat selection of such free-ranging beef cattle, for grazing and resting. We equipped sixteen female adult cows...

  12. Associations between precision sensor data with productivity, health and welfare indicator traits in native black and white dual-purpose cattle under grazing conditions

    Contributor(s):: Jaeger, Maria, Brügemann, Kerstin, Brandt, Horst, König, Sven

    The aim of the study was to analyse the relationships between conventional production as well as subjectively scored welfare assessment traits with longitudinal sensor measurements (i.e., behavioural activity traits) of dual-purpose cattle kept in grazing systems. Such aim implies getting...

  13. Behaviour of White Fulani calves grazing panicum/stylo pasture in Southwest Nigeria

    Contributor(s):: Jimoh, Saheed Olaide, Adeleye, Oluwagbemiga Olanrewaju, Dele, Peter Aniwe, Amisu, Ahmed Adeyemi, Olalekan, Qayyum Olawunmi, Jolaosho, Oluwafunmilayo Alaba, Olanite, Jimoh Alao

    The objective of this study was to investigate the behaviour of White Fulani (WF) yearling calves grazing a Panicum maximum/Stylosanthes guianensis mixture under traditional management system in south western Nigeria. The effects of two biomass spatial distribution (dense and sparse) were...

  14. Behavioral patterns of (co-)grazing cattle and sheep on swards differing in plant diversity

    Contributor(s):: Cuchillo Hilario, Mario, Wrage-Mönnig, Nicole, Isselstein, Johannes

    Both botanical composition and the presence of additional grazer species may modify the grazing efficiency and ingestive behavior of ruminants. However, at present, potential effects of interactions between sward diversity and presence of multiple animal species on the grazing behavior of cattle...

  15. Effects of early experience and alternative feeds on medusahead (Taeniatherum caput-medusae ssp. asperum) intake by sheep

    Contributor(s):: Montes-Sánchez, Juan J., Villalba, Juan J.

    The goals of this study were to test the effects of early experience at grazing medusahead – an invasive unpalatable weed – and the availability of forage alternatives on intake of medusahead later in life by sheep. The study involved two experiments of 10 days each. During Experiment 1, 29...

  16. Spatial and temporal activity of cattle grazing in Mediterranean oak woodland

    Contributor(s):: Schoenbaum, Iris, Kigel, Jaime, Ungar, Eugene D., Dolev, Amit, Henkin, Zalmen

    We examined the temporal and spatial variation patterns of the grazing activity of free-ranging cattle in Mediterranean oak woodland in the Western Galilee, Israel, as affected by seasonal and management factors. The vegetation is dominated by scrub-oak woodland (Quercus calliprinos Webb.),...

  17. 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...

  18. Using a three-axis accelerometer to identify and classify sheep behaviour at pasture

    Contributor(s):: Alvarenga, F. A. P., Borges, I., Palkovič, L., Rodina, J., Oddy, V. H., Dobos, R. C.

    Identifying and classifying feeding behaviour in free-ranging ruminants will help improve efficiency of animal production. Another potential benefit would be in understanding the role behaviour has in determining heritability of methane measurement. The aim of this study was to determine the...

  19. 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...

  20. 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...
