Desparasitación de nemátodos gastrointestinales en ovinos de encaste pelibuey-blackbelly (Ovis aries L.) con hoja de Nim (Azadirachta indica J.) en el Centro de Capacitación Chinampa, San Salvador, El Salvador

Abstract

The research was Conducted at the Training Center Chinampa,San Salvador, El Salvador, in the period november 2014 to may 2015. The effect of the sheet was evaluatedNim (Azadirachtaindica J.), as an internal dewormer against gastrointestinal nematodes in sheep mating pelibuey-blackbelly. Divided into twenty five sheep were used blocks, each of five different age consisting ranges. Nimleaf infusion at two different concentrations (0.12% and 0.24%) was prepared, and supplied to sheep orally for nine consecutive days (T1 and T2), the third treatment (T3) Levamisole was supplied orally. The control treatment (T0), it was fed 0.9% saline orally. Then stool samples on days 0, 7, 14, 21, 28 and 35 for the parasite load were taken, and performing the McMaster technique. The variables were parasite load, effectiveness and weight. A comparison of costs. The findings and conclusions were: the parasitic load decreased with the application of infusions of 0.12% and 0.24% of Nim and levamisole, from 21 to 35, the parasitic load was like for T1, T2 and T3, and had years of 88.52%; 92.86% and 96.87% respectively. The weight increased in all treatments and no effect on the end of these weights, but on age and initial weight, significantly affect the end weights, and was not related to the parasitic load. The T3 was the one who had the highest cost, followed by T2 and T1 was lower cost.
