In recent research it has been demonstrated that the presence of the legume Teramnus labialis , in citric covering, can reduce the brousing of sheeps to this plantation. However, this result could be deterrninated by the animal previous adaptation to the consumption of this plant. On the other hand, previous research has not been able to deterrnine...

The presence of the legume Teramnus labialis SW cv. dark seed in the soil cover of citric plantations seems to reduce ovine browsing to the branches of the fruit-bearing significantly. However, this behavior could have been determined by previous adaptation of the animals to the consumption of this species, and palatability of the legume. In the pr...
