The aim of this study was to evaluate the Enhanced Vegetation Index (EVI) variation between crop-livestock integration (iLP) and extensive (EXT) systems, as well as between crop-forest-livestock integration systems (iLPF) with 14 and 22 m of trees spacing. For EVI values extraction from each production system, 33 images were used between April 2013 and October 2016, 24 in dry periods, between April and September, and 9 in rainy periods, between October and March. For iLP x EXT, in the rainy periods a difference between 8 of the 9 evaluated dates (88.9%) was observed. In 7 of these 8 dates, the iLP presented higher EVI values than the EXT (87.5%). In the dry periods, the difference occurred in 18 of the 24 dates (75%). In 10 of the 18 dates, the iLP presented mean values of EVI greater than the EXT (55.6%). For ILP14 x iLPF22, rainfall periods differed in 7 of the 9 dates (77.8%). Of the 7 dates, in 4 of them, the iLPF14 had EVI values higher than the iLPF22 (57.1%). In dry periods, the difference occurred in 22 of the 24 dates (91.6%). Of the 22 dates, in 19 of them, the iLPF14 had EVI values higher than the iLPF22 (86.4%). In the whole period, discrimination between the iLP x EXT and iLPF14 x iLPF22 systems was observed in 78.8% and 87.9% of the analyzed dates, respectively. |

The goal of this study was to describe the sexual behavior in female and male collared peccary. Twenty females and twelve males were monitored in familiar and non-familiar units for two 60 days periods. During both phases, we recorded 2747 sexual interactions initiated by 20 different females toward males and 4461 sexual interactions initiated by 12 males toward females. The frequency of sexual interactions initiated per female significantly increased from proestrus to estrus, and they were significantly more frequently courted. Females initiated olfactory inspections 15.42 times more and were mounted 22.6 times more during estrus than during proestrus. Nulliparous and primiparous females copulated only when exposed to non-parental males. After estrus, the frequency of sexual interactions received by females sharply decreased. One mating event was recorded during the first gestation week and 31 mountings were observed after the second week. In conclusion, the behavioral monitoring is a useful procedure for the recognition of estrus. Our results suggest that ovulation may be associated with the end of the estrus, which will support future work in assisted reproduction in this species. To promote good handling practices, females of reproductive age should be removed from their family unit of origin. |
