Cím:	Detailed analysis of cattle behavour on rangeland under free range grazing system / Halasz A., Nagy G., Tasi J., Bajnok M.
Dátum:	2016
Megjegyzések:	Behaviour of Hungarian grey cattle was observed under range grazing conditions during four grazing seasons. The actual behaviour of cattle was recorded 3 times an hour, during investigated grazing days. Selected animals were tagged with GPS recorders which made it possible to detect their position on the pasture and to calculate the daily covered distance. Detected behavioural traits were recorded in behavioural journals (ethograms). These records allowed us to describe the animals' detailed daily routine.The daily behavioural pattern built up from feed intake-metabolic (47.7%), social (25.9%), move (23.1%) and sexual (3.3%) behaviour traits. New traits (watch, sentinel, threefold division) were revealed and redefined (for this breed only), contrasting with previously published papers. The daily travelled distance covered by cattle, ranged between 1-5 kilometres. It was mostly influenced by the weather-front changes throughout barometric pressure dynamics. Grazing preference showed remarkable differences. Sward quality and the proximity of water had the greatest influence on the intensity of pasture use.
