Mostrar todas las versiones(2)

The present study was carried out during 105 days in Pilagás (For-mosa, Argentina) to evaluate the effect of Leucaena sp consumed by weaned calves on the gastrointestinal parasitic load. Thirty calves were divided into two groups: grazing Leucaena (TREATED with/L; n=15) or without consumption of Leu...

description The present study was carried out during 105 days in Pilagás (For-mosa, Argentina) to evaluate the effect of Leucaena sp consumed by weaned calves on the gastrointestinal parasitic load. Thirty calves were divided into two groups: grazing Leucaena (TREATED with/L; n=15) or without consumption of Leucaena (TREATED without/L; n=15). This essay was performed in a direct grazing system and animals were naturally infected under the conditions of Pilagás forage. Animals in the TREATED with/L group grazed in an interseeding of Leucaena leucocephala with Bra-chiaria brizantha while the TREATED without/L group grazed only on B. brizantha. Eggs per gram (EPG) were determined from feces. Fecal culture and identification of larvae were also performed for each experimental group. Hemotocrit (Ht) was measured and animals were weight. The main genera recovered in the fecal samples were: Haemonchus, Trichostrongylus, and Bunostomum. Oesophagostomum, Cooperia and Strongyloides were less abundant. Since the second sampling, animals with Ht ≤ 22% required albendazole administration since health was compromised. During the whole study, only one calf under TREATED with/L required treatment, whereas in the other group (TREATED without/L) nine animals needed treatment. In relation to EPG, signif-icant differences were registered for the second and forth sampling (p value of 0.3 and 0.006, respectively) in favor of TREATED without/L group. We conclude that under the conditions for the present study, L. leucocephala intake exerts an effect over EPG. Therefore, future assays should be performed for a better understanding regarding an alternative integral control of parasites.

Se seleccionaron 30 terneros y se los dividió en dos lotes: 15 terneros con Leucaena (TRAT c/L) y 15 sin Leucaena (TRAT s/L). El ensayo se desarrolló en un sistema de pastoreo directo donde los animales fueron infestados naturalmente. El lote TRAT c/L pastoreó en una intersiembra de L. leucocephala con Brachiaria brizantha. El grupo TRAT s/L, lo hizo sólo con B. brizantha. Se determinó la cantidad de huevos de parási-tos por gramo (HPG), cultivo e identificación de larvas, valores de hematocrito (Hto) y peso vivo. Los principales géneros recuperados en el coprocultivo fueron: Haemonchus y Trichostrongylus, siguiendo en orden decreciente Bunostomum, Oesophagostomum, Cooperia y Strongyloides. A partir del segundo muestreo, los animales que presentaron valores de Hto ≤ 22% debieron ser tratados con albendazol ya que estaba comprometi-do su estado de salud. Durante el ensayo un solo ternero del TRAT c/L debió ser trata-do, mientras que 9 individuos correspondientes al TRAT s/L requirieron tratamiento. En cuanto a la evolución de HPG, se observaron diferencias significativas en el segundo y cuarto muestreo (p valor de 0,3 y 0,006 respectivamente) a favor del TRAT s/L. Se con-cluye que bajo las condiciones de la presente experiencia, los resultados demostraron un efecto del consumo de L. leucocephala sobre la disminución de HPG, lo que amerita la realización de futuras experiencias para un mejor conocimiento de la alternativa de con-trol integrado de estos parásitos.  Universidad Nacional del Nordeste 2019-12-17 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion application/pdf application/pdf https://revistas.unne.edu.ar/index.php/vet/article/view/4127 10.30972/vet.3024127 Revista Veterinaria; Vol. 30 Núm. 2 (2019); 1-10 1669-6840 1668-4834 spa https://revistas.unne.edu.ar/index.php/vet/article/view/4127/3765 https://revistas.unne.edu.ar/index.php/vet/article/view/4127/6389 Derechos de autor 2019 C.
