Nestas
fotografias podemos observar caprinos consumindo frutos e folhas do imbuzeiro. As fotografias foram obtidas no município
de&nbsp;Petrolina,&nbsp;PE.















































Os fatos



Na região semiárida do Nordeste
brasileiro a agricultura convive com uma série de adversidades, tendo na
escassez dos recursos hídricos, sua principal restrição. Por outro lado, fator
de natureza, física, biológica e socioeconômica tem contribuído para que a
produção agrícola não atinja os objetivos desejados. Todavia, algumas plantas
nativas da região semiárida, de modo especial, o imbuzeiro ou umbuzeiro (Spondias
tuberosa Arruda) adaptando-se as intempéries climáticas que assolam a
região e apresenta&nbsp; boa produção,&nbsp; possibilitando&nbsp; o extrativismo do seu fruto pelos pequenos
agricultores, constituindo-se como fonte complementar de sua renda e muitas
vezes, como a única fonte de renda para algumas famílias rurais. Quanto aos
animais, um estudo realizado na &nbsp;comunidade de Alta do Angico no município de
Petrolina, PE, demonstrou que, em média, são consumidos 26,47 kg de folhas verdes
por planta pelos animais na estação chuvosa. Esse volume de folhas consumidas
demonstra a palatabilidade desta planta, visto que, no período de consumo, a
vegetação da caatinga é muito variada em função das chuvas. No período de queda
das folhas do imbuzeiro, foram consumidos, em média, 39,52 kg de folhas maduras
e secas caídas ao solo embaixo das plantas. Já com relação aos frutos, os
animais consumiram, em média, 9.172 frutos num período de safra. O maior número
de frutos consumidos por um animal foi de 11.760 frutos. Esse volume
correspondeu a um consumo médio de 10,92% do peso vivo do animal. O peso
estimado dos frutos consumidos por animal foi de 162,91 kg. A quantidade
média de frutos consumida por dia foi de 157,42 frutos com peso estimado de 2,80 kg por animal.
