Determining cattle pasture utilization using GPS-collars
This study was conducted in Jaboticabal, Brazil, on Nelore cattle. Three heifers on the same pasture were equipped with GPS-collars registering position and activity, allowing us to calculate distance to the other collars and distance to the water source.

| description | This study was conducted in Jaboticabal, Brazil, on Nelore cattle. Three heifers on the same pasture were equipped with GPS-collars registering position and activity, allowing us to calculate distance to the other collars and distance to the water source. After one week the GPS-collars were taken of and put on three heifers on another pasture. This was repeated on seven different pastures on total 21 heifers. The results indicate that the cattle are more active during the afternoons than in the mornings and have a shorter avtiviyu period during the night. In conjunction with the results of Einemo (2008) it is concluded that the high activity during the afternoon means the animals are mainly grazing during that period. Results show the cattle spread out when active but like to huddle up together while resting. Compared to when active, the animals also seem to prefer to rest at a distance from the water. |

Three heifers on the same pasture were equipped with GPS-collars registering position and activity, allowing us to calculate distance to the other collars and distance to the water source. After one week the GPS-collars were taken of and put on three heifers on another pasture. This was repeated on seven different pastures on total 21 heifers.

Denna studie skedde i Jaboticabal, Brasilien på boskap av rasen Nelore. Tre kvigor på samma bete blev utrustade med GPS-halsband som registrerade djurens position och aktivitet så att vi kunde beräkna avståndet mellan de andra halsbanden och till djurens vattenbehållare. Efter en vecka togs halsbanden av och sattes på tre andra kvigor på ett nytt bete. Totalt användes sju betesmarker och 21 kvigor. Resultaten visar att djuren är mer aktiva under eftermiddagarna än under morgon och förmiddag samt under en kortare perido på natten. Kombinerat med resultaten av Einemo (2008) drar jag slutsatsen att den höga aktiviteten under eftermiddagen betyder att djuren främst spenderar den tiden med att beta. Resultaten visar att djuren är utspridda medan de betar men vilar tillsammans i grupp. Jämfört med deras aktiva tid verkar djuren föredra att vila på avstånd från vattenkällan.
