CASTILLO-MITRE, Gastón Federico et al. In vivo anthelmintic activity of Acacia cochliacantha leaves against Haemonchus contortus in Boer goat kids. Rev. mex. de cienc. pecuarias [online]. 2021, vol.12, n.1, pp.138-150.  Epub 20-Set-2021. ISSN 2448-6698.  https://doi.org/10.22319/rmcp.v12i1.5131.

This study aimed to evaluate the effect of supplementing the maintenance diet of Boer goat kids with Acacia cochliacantha leaves. The endpoints evaluated were Haemonchus contortus fecal egg count (FEC) and water and dry matter intake. Two experimental treatments were evaluated on ten recently weaned goat kids (16.850 ± 1.630 kg of initial live weight and three months of age) experimentally infested with H. contortus larvae (L3) (350 larvae per live weight kilogram). Treatment 1 (T1) served as the control and consisted of infested animals without diet supplementation with A. cochliacantha leaves. Treatment 2 (T2) consisted of infested animals fed diets supplemented with 5% of A. cochliacantha leaves. Animals were grouped from highest to lowest based on their FEC. The two animals groups with the highest values were randomly assigned to T1 or T2; this was repeated until completing five repetitions per treatment. The evaluated variables were: FEC (per gram of feces), water intake, and dry matter intake (DMI). The results show that goat kids fed diets with 5% of A. cochliacantha leaves have lower (P<0.05) FEC than the control. There were no significant differences in water intake and DMI (g d-1) between treatments. This study demonstrates the anthelmintic activity of diets supplemented with A. cochliacantha leaves in goat kids. Thus, this arboreal legume could represent a viable option for the comprehensive management of the nematodiasis of growing Boer goat kids.
