Aplicação dos sistemas de informação geográfica para definição de estratégias de manejo de bovinos nas pastagens

Abstract: RESUMO -O estudo de grandes áreas de pastejo, principalmente no que diz respeito ao seu uso pelos animais, é difícil, tanto na forma de amostragem, quanto na maneira de analisar os dados obtidos. Nesse contexto o Sistema de Informação Geográfica (SIG) surge como ferramenta útil, capaz de viabilizar estudos ecológicos e comportamentais associados ao uso do espaço e dos recursos nele alocados. Dentre as ferramentas principais de um SIG com importância para o estudo de ecologia de pastagens, podemos citar a deter… Show more

“…In #FDM lower than 1,823 kg/ha, the regions with the highest temporal concentration of animals and excessive trampling, known as resting place (where the cattle remain the longest) were observed, which in the study area comprised the drinking trough, tree shades and mineral supplementation trough (northeast region), and the vicinity of an old mineral supplementation trough (northwest region). Similar results were reported by Páscoa & Costa (2007), who were also using the kriging geostatistical technique. Conversely, the proximity to the handling corral (southeast region) and the tracks set up in parallel at the borders of the south and west regionslocations where there is normally a high traffic of people, which inhibits animal grazing -as well as superficial depositions of nutrients in the soil and the lower access of animals in lower regions (southwest and southeast), may all have contributed to the occurrence of higher #FDM values.…”

“…Thus, the action exerted by animal grazing represents a decisive fact in increasing its spatial heterogeneity (Bertol et al, 2006;Páscoa & Costa, 2007). Therefore, both for bulk density (BD) and mechanical resistance to penetration (RP), combined with the fact of possible superficial soil compaction by animal trampling, the higher coefficients of variation found at the depth of 0-0.10 m attest that over the years grazing increased soil surface heterogeneity.…”

“…Modificações do padrão de pastejo dos animais, induzidas por qualquer característica com dependência de distribuição espacial, podem interferir no desempenho dos animais e na otimização do uso da pastagem (Páscoa & Costa, 2007). A forma com que os animais exploram as estações alimentares determina seu nível de consumo, uma vez que as regras de escolha e de abandono das mesmas afetam a ingestão de forragem e a eficiência do processo de pastejo (Carvalho & Moraes, 2005).…”
