The pods of Enterolobium spp (Leg.Mimosoideae) are said to cause photsensitivity and abortion in cattle. The pods of E. contortisiliquum and E. timbouva ("tamboril" or "timbaúba"), collected at various localities, in two occasions during outbreaks of photosensitization and abortions, were fed in single and repeated doses to young bovines and to cows in calf. In ali experiments the animals showed only diarrhoea and loss of apetite, as it had been already seen in previous experiments with E. contortisiliquum performed in Fortaleza, northeastern Brazil. Also it was seen again that the animals become tolerant to the toxicity of the pods if they get successive doses. The experiments did not reveal possible conditions necessary for the pods of Enterolobium contortisiliquum and E. timbouva to cause photosensitization and/or abortion. |
