Eimeria control in baby alpacas using toltrazuril as a prophylactic measure in humid Puna

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: G 1 treated with 15 mg/kg of live weight (LW) of toltrazuril orally (VO), G 2 with 18.7 mg/kg BW/PO, G 3 with 22.5 mg/kg, G 4 with 30 mg/kg and G 5 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.
