| Résumé : |
Prickly pear or Barbary fig (Opuntia ficus indica L Mill) is a plant growing in arid and semiarid regions, besides its oil which is among the richest oils in the world, this plant is characterized by its many therapeutic virtues.
In our first study, the burn healing effect of the aqueous extract of the cladodes (pads) of Opuncia ficus indica as well as the effect of the mixture of this extract with the fruit seeds powder, was evaluated on experimental burns in a rabbit model. The results obtained confirm the positive effect of the plant in the healing process, by significantly reducing the wound area through accelerating wound contraction, which lead to a shorter healing time compared to the control and the cicatryl® groups. Histological study showed that wounds treated with presented a thinning of the epidermis and a neovascularization of the granulation tissue with a good distribution of sudoriparous and sebaceous structures and a formation of a surface keratin layer favourable for good tissue
regeneration. Several wounds treated with the cladodes’ aqueous extract presented a normal restitution
of the initial aspect of the skin (ad integrum).
Our second study conducted on broiler chicken aimed to test the effect of the incorporation of the seeds of the fruit of Opuntia ficus indica in the birds’ feed as well as the addition of the aqueous extract of the cladodes in their drinking water. Products were aded using different concentrations 1%, 2% and 5%. The results obtained in terms of weight, feed conversion ratio and carcass yield are better in the experimental group (5%). Blood biochemical parameters were not modified by this incorporation, and remained in the physiological norms.
An increase in liver and kidneys weights of the birds supplemented with 5% fruit seed was observed but has no impact on the functioning of these two organs. In fact, the majority of the histological sections showed a conserved overall morphology of the liver and the kidneys, which testifies the safety of our plant.
Thus, at the end of this study, we can say that Opuntia ficus indica (Fruit seeds and cladodes aqueous extract), respectively incorporated in the feed and drinking water at 5%, improves both live and carcass performances of broilers, compared to 1% and 2% complementation. However, other studies should be undertaken in order to provide a better exploitation of this plant.
