In order to evaluate the anthelmintic effect of condensed tannins (TC), a study was made to evaluate its effect on gastrointestinal nematodes (NGI) in goats and sheep. Two groups of 6 goats and 4 sheep grazing Lucerne were assigned; one group without treatment (GST) was daily supplemented with ground corn (500 g), while the other group (GTC) with the same diet and the inclusion of 25 g of TC. Faecal nematode egg counts (epg) and coprocultures were made every two weeks for 3 months. In addition, FAMACHA technique and body condition score (CC) were recorded. The epg were similar in the first three samplings (mean= 507.4 GTC y 351.4 GST), then the GST epg decreased being lower than those of the GTC, but without significant differences (p <0.096) between groups, between sampling dates (p <0.66) not even in group per sampling date interaction (p <0.99). From faecal cultures Haemonchus (64.6%) predominated in GTC and Trichostrongylus (45.8%) in GST; Teladorsagia was recovered under low percentages. FAMACHA score did not show differences (p <0.46) between groups, averaging 2.11 ± 0.66 and 1.83 ± 0.71 respectively for GTC and GST. The CC averages were 2.93 ± 0.65 and 3.16 ± 0.54 respectively for GTC and GST and differences weren’t found (p <0.42). It concluded that under the conditions of this study with low NGI burdens, the condensed tannin dose of 25g in 500g of corn represents a low dose without anthelmintic effect. |

Con el objetivo de evaluar el efecto antihelmíntico de los taninos concentrados (TC) se realizó su estudio sobre los nematodes gastrointestinales (NGI) en caprinos y ovinos. Se asignaron dos grupos compuestos de 6 cabras y 4 ovejas cada uno en pastoreo de alfalfa; un grupo sin tratamiento (GST) suplementado con 500 g de maíz molido y otro (GTC) con igual suplemento más la adición diaria de 25 g de TC. Cada dos semanas durante 3 meses se realizaron conteos de huevos de NGI por gramo de heces (hpg) y coprocultivos. Además, se registró la condición corporal (CC) y el grado de FAMACHA. Los hpg fueron bajos y similares en los primeros tres muestreos (promedio= 507,4 GTC y 351,4 GST), luego los hpg del GST disminuyeron resultando inferiores al GTC, pero sin diferencias significativas (p<0,096) entre grupos, entre fechas de muestreo (p<0,66) ni entre la interacción grupo por muestreo (p<0,99). En los coprocultivos se observó, un predominio de Haemonchus (64,6%) para GTC y Trichostrongylus (45,8%) para GST; en todos se recuperó en bajo porcentaje Teladorsagia. Los datos obtenidos del score Famacha no mostraron diferencias significativas (p<0,46), promediando 2,11 ± 0,66 para el GTC y 1,83 ± 0,71 de score para el GST. Los promedios de CC fueron 2,93 ± 0,65 y 3,16 ± 0,54 respectivamente para el GTC y GST, sin diferencias significativas (p< 0,42). Bajo las condiciones del presente estudio con una baja infestación, 25g de taninos concentrados en 500g de maíz representó una dosis sin efecto antihelmíntico Universidad Nacional del Litoral 2019-01-14 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Artículo original Original article application/pdf https://bibliotecavirtual.unl.edu.ar/publicaciones/index.php/FAVEveterinaria/article/view/7891 10.14409/favecv.v17i2.7891 FAVE Sección Ciencias Veterinarias; Vol. 17 Núm. 2 (2018): FAVE Sección Ciencias Veterinarias; 55-60 FAVE Sección Ciencias Veterinarias; Vol. 17 No. 2 (2018): FAVE Sección Ciencias Veterinarias; 55-60 FAVE Sección Ciencias Veterinarias; v. 17 n. 2 (2018): FAVE Sección Ciencias Veterinarias; 55-60 2362-5589 1666-938X 10.14409/favecv.v17i2 spa https://bibliotecavirtual.unl.edu.ar/publicaciones/index.php/FAVEveterinaria/article/view/7891/11434 Derechos de autor 2019 Gabriela V.
