5. Conclusion In conclusion, the anthelmintic cassava foliage have been demonstrated. properties of wilted These proper- ties were linked to the condensed tannin content of the foliage. Condensed tannins restricted the excretion and development of H. contortus eggs. An eventual action of CT on the fertility H. contortus female worms is suspected but remains to be demonstrated in other trials. Unfortu nately, as a result of a high fill effect. the intake of old wilted cassava foliage limited the total energy intake of the animals. with a subsequent depressive effect on growth. strategy would be to use younger foliage An alternative to optimise the anthelmintic properties and nutritional values.
