SUMMARY:

Sheephaveparticularities in theiringestivebehavior and studieson its components, such as period and duration of grazing, food preference and the applicability of its effectsonproduction systems can help toavoidlosses. The use of precisiontechnologiessuch as the use of the Global Positioning System (GPS) seekstocontributeto the accuracy of informationaboutanimals and the environment, with the aim of reducingerrorsregarding the behavior of sheep. The objective of thisstudywastoevaluate the behavior of pasture-raisedsheepsubjectedto four integrated crop and livestock systems in the caatinga biome. The treatmentsconsisted of threeintegration systems: 1. beanscultivated in the Caatinga; 2. corngrown in the Caatinga; and 3. herbaceouscottongrown in the Caatinga, plus a controltreatment: 4. Caatinga only. Animal behaviorwasevaluatedusing the scanningmethod for a consecutiveperiod of 24 hours, in additiontomonitoringby the Global Positioning System (GPS). Therewassignifficanteffect (P<0.05) for the grazing time variable, where the animalsthatremained in the cornintegration system spent more time in grazingactivity, whencomparedto the othertreatments. For the variablesrumination time and idleness, no significantdifferences were observed. However, the animalspresented in alltreatmentsestablishedperiods of grazing, rumination and idlenessduring the 24-hour evaluation. No significantdifferences (P>0.05) were observedbetweentreatments for the followingvariables: walking, elevation, grazing time and grazingspeed. For Kernel density, a significanteffectwasobtained (P<0.05), obtaining a highervalue for the Caatinga treatment and a lowervalue for the animalsswitched off in the corntreatment. Thisfactmayhavebeenattributedto the factthatsheep show greaterresistancetograzing in areaswithdenser and tallervegetation, thuschoosinggrazing sites in the paddock thatonlyhad caatinga. Althoughthere are manyfactorsthatcanchange the ingestivebehavior of sheep, the integration systems presentedfavorableconditions for the production of sheep in the caatinga biome.
