  3. 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...

  4. 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...

    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...

  6. 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...

  7. 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...

  8. 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...

  9. 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...

  10. 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...

  11. 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...

  12. 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.),...

  13. 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...

  14. Behavioural response of pure Ankole and crossbred (Ankole×Holstein) 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...

  15. Location of supplementary feed and water troughs on the sward affects movement and spatial distribution of Brahman cattle (Bos indicus)

    Contributor(s):: Solano, Jaime, Averós, Xavier, Clemente, Neftalí, Aguirre, Virginio, Estevez, Inma, Orihuela, Agustín

    The grazing dynamics of animals differ depending on whether they are raised on rangeland or sward areas. Grazing patterns of cattle raised on rangeland can be modified by the location of supplement feed and water troughs. However, no information about the use of this strategy is available for...

  16. Influence of off-stream watering systems on cattle behaviour adjacent to Lower Little Bow River in Southern Alberta

    Contributor(s):: Miller, J. J., Curtis, T., Rogness, D., Willms, W. D., Chanasyk, D. S.

    Off-stream waterers (OSWs) located in upland pastures may be effective in reducing livestock impacts on riparian areas and rivers, but little research has been conducted on the impact of OSWs located closer to rivers. We studied cattle behaviour over four years (2012-2015) for a portable OSW at...
