Abstract
Con los objetivos de determinar la eficacia del toltrazuril como profilácticas sobre el control de eimerias y determinar la dosis profiláctica frente a las especies de eimerias en crías de alpacas situadas en puna húmeda, se realizó un estudio en el Centro de Investigación de Camélidos Sudamericanos La Raya Cusco Perú, se identificó 50 crías de alpaca de 3 a 4 meses de edad distribuidas en 5 grupos de 10 animales cada uno: G1 tratadas con 15 mg/kg de peso vivo (PV) de toltrazuril por vía oral (VO), G2 con 18.7 mg/kg PV/VO, G3 con 22.5 mg/kg, G4 con 30 mg/kg y G5 sin dosificación alguna (grupo control). Se realizó el análisis coproparasitológico antes de dosificar (día 0) y a los siete días post-tratamiento. El análisis se realizó por el método de MacMaster modificado. Los datos se sometieron a análisis de varianza y a la prueba de Fisher. Los resultados señalan que utilizando 15 mg/kg PV y 18.7 mg/kg PV de toltrazuril se controla solamente especies pequeñas como Eimeria punoensis E. alpacae y E. lamae, mas no la especie grande (E. macusaniensis) y con 22.5 y 30 mg/kg PV además de controlar especies pequeñas también se reducen significativamente la eliminación de ooquistes de E. macusaniensis (p≤0.05). Se concluye que la dosis profiláctica para controlar eimerias en crías de alpacas fue de 22.5 y 30 mg/kg PV, con una sola aplicación por vía oral, logra controlar las cuatro especies registradas en este trabajo.
An effective concentration of toltrazuril to prophylactics in the control of eimerias and determine the prophylactic dose against eimerias species was evaluated in cria alpacas of the La Raya research center in Cusco Peru. Fifty cria alpacas of 3-4 months of age. distributed in 5 groups of 10 animals each: G1 treated with 15 mg/kg of live weight (LW) of toltrazuril orally (VO), G2 with 18.7 mg/kg BW/PO, G3 with 22.5 mg/kg, G4 with 30 mg/kg and G5 without any dosage (control group). All dosage was given orally. Fecal analysis was performed using the modified McMaster technique at time 0 ad seven days later. Data were analyzed using analysis of variance and a Fisher test was done to determine statistical significance. The results indicate that using toltrazuril 15 mg/kg BW and 18.7 mg/kg BW, only small species such as Eimeria punoensis E. alpacae and E. lamae are controlled, but not the large species (E. macusaniensis) and with 22.5 and 30 mg/kg LW, in addition to controlling small species, the elimination of E. macusaniensis oocysts is also significantly reduced (p≤0.05). It is concluded that the prophylactic doses to control eimerias in baby alpacas is 22.5 and 30 mg/kg BW, with a single oral application, which manages to control the four species registered in this work.
