摘要: Abstract The work consisted of the evaluation photosensitization in sheep grazing signal grass (Brachiaria decumbens) a silvopastoral system or under full sunlight for 60 days summer. We hypothesized that shade provided by trees prevents alleviates classic symptoms and affects concentration saponin protodioscin grass. Twenty naive crossbred (Dorper x Santa Ines) were used randomized block design, with two blocks five animals per block. Animals both sun treatments grazed B. decumbens, presented clinical symptoms, alterations liver, increased serum levels gamma-glutamyltransferase (GGT), aspartate aminotransferase (AST), bilirubin over duration experiment. Although content decumbens was lower than treatment, it sufficient to cause secondary animals. natural shading does not prevent ameliorate young on decumbens.
