Determinación de valores hematológicos, química sanguínea y tamaño de vellosidades intestinales con el uso de probióticos en pollos de engorde

Abstract

The present investigation was carried out in the San Camilo sector located in the Biblián city, Cañar province; whose objective was to determine the effects of the inclusion of probiotics during the rearing stage in broilers both in the hematological assessment and in the size of intestinal villi. For the development of the research, a group of 600 Cobb-500 one-day-old chicks was used, which were distributed in two treatments, made up of 300 birds: T1: control, T2: substrate (molasses-vinasse) fermented with Lactobacillus. acidophilus and L. bulgaricus; the histological size of the intestinal villi was evaluated at 49 days; in addition, the hematological values were prolonged by complete blood count and blood chemistry. In the results: no differences (p ≥ 0.05) were found between the treatment means in the hematological variables, blood chemistry or intestinal villi in chickens. Variables altered from their normal range were observed in the hematological analysis, such as PCT with a lower T1 and T2 value (Table 5). In blood chemistry, variables altered from their normal range were determined in AST, ALT, ALP, TBA, LPS, CK, CREA (table 7).
