Efecto del ajo (Allium Sativum) sobre los índices de producción y Eimeria spp en pollos de engorde

Abstract

The aim of this study was to analyze different percentages of addition garlic (A. Sativum) in different doses on the productive indexes and the oocyst count of Eimeria spp, for which four treatments were used: T0: control without addition of (A. Sativum); T1: with 0.15% of (A. Sativum); T2: with 0.25% of (A. Sativum) and T3: with 0.3% of (A sativum). It was evaluated in 160 broilers of the cobb 500 line, one day old. By means of an experimental design with 4 replicates by treatment and 10 animals by replicate, the data obtained were evaluated with Tukey’s statistical test with a significance level of 95% using InfoStat as the statistical program. The productive period was divided into three stages: Initial (8-12 days); Growth (13-28 days) and Fattening (29-49 days) while samples were taken to count oocyts of Eimeria spp on days 35 and 49, for which 10 animals by treatment were sacrificed to obtain fecal samples directly from the intestine, which were evaluated in the laboratory with the floatation technique an the McMaster chamber. The best results were obtained with the T3 treatment with the addition of (3%) of (A. Sativum), finding better results in productive indexes with a weight gain of (2411.98 g) and a feed conversion of (2.08). It also showed a lower quantity of oocysts by g/feces and a good cost/benefit of 1.20. Key words: broilers, A. Sativum, productive indexes, Eimeria spp.
