| Cattle predation by jaguars in the north of the state of Goi s | |
| 2004 Full Book | |
Data on cattle predation by pumas (_Puma concolor_) and jaguars (_Panthera onca_) has been recorded for six years in a farm in Northern Goi s, Mid-Western Brazil. This research's main objectives were to determine: (1) the actual proportion of cattle killed by big cats; (2) whether there was a certain age class targeted by those predators; (3) whether the predation fluctuated along the year and (4) the spatial distribution of cattle predation. Data were recorded by employees and cattle managers using forms with the following information (observer's name, date, id numbers, cause of mortality, age and sex). Predation represented 21,7% (n=309) of the overall cattle mortality. In biomass, kills represented 0,4 % of the farm' annual stock with 63,8 kg/kmę. Predation was strongly correlated with cattle's age with most attacks occurring on calves younger than 2 months old then gradually decreasing the animals get older. Predation was mainly associated with cattle's age class and location along with the time of the births it occurred. It clearly appeared that cattle predation varied spatially and temporally. We recommended several preventive techniques to be used in order to limit cattle predation in rural farming contexts so as to reduce the conflict between villagers and large felids and thus enhance the last big cats' conservation. |
