| 1 | Understanding sheep baa-haviour: Investigating the relationship between pasture and animal grazing patterns显示文摘Background:Grasslands are the primary source of feed for grazing livestock,and as such,knowledge on how to best manage livestock and grasslands,through the use of spatiotemporal modelling,will assist in the long-term management of a valuable ecosystem resource.Methods:This study was conducted over 14 months between March and April 2017 in Orange,NSW,Australia.The study evaluated sheep behaviour in relation to the presence of pasture species,environment and paddock structures,using random forest modelling,to predict sheep location under continuous high(HSR,13 DSE ha−1)and low(LSR,7DSE ha−1)stocking rates.Results:In the LSR,significant drivers included water,shade and fence lines(p<0.01).In the HSR,only fence lines and available biomass were found to be significant(p<0.01).The presence of green legumes in both stocking rates often increased residency by sheep.Animals spent more time together in the LSR,suggesting that social behaviour played a larger role than pasture quantity and quality in driving grazing behaviours.Conclusions:Understanding how pasture type can influence grazing behaviours and also how animal behaviour affects pasture performance and utilisation is important in developing long-term sustainable management strategies on a paddock scale. | Danica Parnell Igor Kardailsky Jacob Parnell Warwick Brabazon Badgery Lachlan Ingram | 2022 | Grassland Research2022，1，3： | 0 |
