Evaluation of anthelmintic properties of Itacha (Dodonea angustifolia) leaves in goats
MetadataShow full item record
BACKGROUND: Medicinal plants have been used for treatment of animal diseases where livestock keepers do not have easy access to modern medicines. Itacha (Dodonea angustifolia) was among the plants identified, in a survey conducted in southern Ethiopia, to have medicinal values. Livestock occasionally consumes Itacha and its leaf extract was found to have strong in vitro anthelmintic efficacy. Here, we assess the impact of feeding Itacha leaves on performance and parasitism in goats. METHODS: A 56 days feeding experiment was conducted using 64 yearling male goats in 2×4 factorial arrangements, where goats were infected or not on day 0 with 3500 Haemonchus contortus larvae, and offered grass hay with supplements containing 0, 35, 70 or 100% air-dried Itacha leaves replacing concentrate mixture. RESULTS: Parasitism and feeding more than 35% Itacha reduced feed intake and body weight gain from day 28 onwards (P<0.05), with increased mortality at 100% Itacha feeding. Feeding up to 70% Itacha linearly reduced total worm burdens (P<0.05) and in utero fecundity (P=0.088); goats fed 35 and 70% Itacha supplements had 38% and 45% fewer worms, respectively, than their non-Itacha fed counterparts. CONCLUSIONS: This study showed that feeding moderate levels of dried Itacha leaves has the potential to reduce worm burdens in goats, though at high levels may be anti-nutritional.
