Abstract
La investigación se desarrolló en la Empresa Agroindustrial Casa Grande, provincia de Ascope departamento La Libertad, el objetivo fue determinar el efecto de dos antiparasitarios orales sobre el tratamiento y control de nematodos gastrointestinales en equinos. Se plantearon dos tratamientos y un control con 15 repeticiones cada uno: T1 Doramectina 3,5 mg/kg de peso vivo y T2 fenbendazole 7,5 mg /kg de peso vivo. Se tomaron muestras fecales en forma seriada directamente del recto por tres días con un día por medio y, a los 30 días post tratamiento, identificándose y conservándose con bicromato de potasio al 2% proporción 1:1; de las muestras seriadas pre y post tratamiento se obtuvo una sola muestra por unidad experimental. Previo a las muestras fecales se aplicó la prueba del parche en la zona perianal. Las muestras fecales pre y post tratamiento fueron analizadas mediante las técnicas de Baermann modificada en copa y Kato-Katz para identificar y cuantificar huevos de nematodos gastrointestinales y la técnica de Graham para determinar oxiuros. El efecto antiparasitario se determinó valorando la eficacia mediante el método del porcentaje de reducción de huevos por gramo de heces (hpg) y estadísticamente con promedios y la prueba de Chi cuadrado. De 45 yeguas analizadas el 100% resulto positivo a nematodos; identificándose huevos de los géneros: Strongylus (492), Ascaris (486) y Oxyuris (+ y -). La eficacia de doramectina fue 98% respecto del fenbendazol 53% (P < 0,01), concluyendo que la doramectina fue altamente eficaz en el control de nematodos gastrointestinales en equinos.
ABSTRACT The research was conducted in the Casa Grande agro-industry Company, in the department La Libertad, province Ascope district casa Grande. The objective was determine the effect of two oral anti-parasitic in treatment and control of gastrointestinal nematodes in horses. Were raised two treatments and control with 15 repetitions each: T1 doramectina 10 mg/kg live weight and T2 fenbendazole 100 mg/kg live weight. were collected fecal samples directly from the rectum three times for 5 days and after 30 days post treatment, were identified and preserved with potassium dichromate 2% 1:1, of the samples collected before and after treatment was obtained one sample for experimental unit. Before fecal samples was applied the patch to the perineum zone. The fecal samples before and after treatment were analyzed by Baermann technique and modified in cup and Kato-Kats to identify and quantify eggs of gastrointestinal nematodes, and the Graham technique to oxiuros. Antiparasitic effect is determined by assessing the effectiveness by the method of reduction percentage of epg and statistically with averages, Chi square test. 45 mares tested 100% tested positive to nematodes. Egos of parasitic identifiyng: Strongylus (492), Ascaris (486) and Oxyuris (+ and -). Doramectin efficiency was 98% compared to 45% Fenbendazole, with statistical difference (P < 0.01), concluding that the doramectin was highly effective in controlling gastrointestinal nematodes in mares.
