“…El efecto esperado del Zn-Bacitracina frente al grupo control negativo confirma el estudio de Rosen (1995) quién demuestra el efecto benéfico de 2 a 8.6% sobre el ICA con el uso de antibióticos promotores de crecimiento. Los antibióticos son usados para mantener un adecuado balance de la microflora del tracto gastrointestinal y para eliminar microorganismos patógenos, facilitando la reducción de enfermedades gastrointestinales (Patterson y Burkholder, 2003).…”

RESUMENEl objetivo del presente estudio fue evaluar el efecto de la suplementación de una cepa probiótica aislada de la microbiota intestinal del cuy sobre sus parámetros productivos. Se utilizaron 80 cuyes machos desde el primer día de edad, distribuidos en 40 unidades experimentales. Se emplearon cinco tratamientos con ocho repeticiones por tratamiento: T1, T2 y T3 recibieron 100, 150 y 200 ml de probiótico, respectivamente, y T4 y T5 fueron los controles positivo y negativo, respectivamente. Se evaluó el consumo de materia seca, ganancia de peso, índice de conversión alimenticia (ICA) y rendimiento de carcasa. T2 presentó el menor consumo de materia seca (2564 g) y el menor ICA (3.90) y T5 el mayor consumo (3293 g) y el mayor ICA (5.04). La ganancia de peso y el peso y rendimiento de carcasa no se vieron afectados por el probiótico. La inclusión en la dieta de cepas probióticas provenientes de la microbiota intestinal del cuy afectó (p<0.05) el índice de conversión alimenticia en la etapa de crecimiento y engorde de cuyes.

“…Over the past few decades, antibiotics have been added to poultry and pig diets to maintain health and production efficiency (Rosen, 1995). There is increasing concern, however, about the risk of developing cross-resistance and multipleantibiotic resistance in pathogenic bacteria (Verdonk and Shim, 2005).…”

This study was conducted to evaluate the effectiveness of inulin on the intestinal microflora, gut morphology, and performance of broiler chickens. After sex identification, 168 male Ross 308 broilers were randomly allotted to 3 treatment groups with 4 replicates and fed for 42 days. Experimental treatments including 0%, 0.5%, or 1% inulin were used. The experimental diets were formulated based on maize-soyabean meal. The results showed that livability and body weight gain were better for broilers fed diets supplemented with inulin, but livability did not vary significantly among groups and the control. Live body weight on d 42 was significantly increased when the diets were supplemented with 1% inulin. Feed intake and feed conversion ratio were not affected in birds fed diets with supplements in comparison with the control group. Inulin inclusion had no effect on Bifidobacteria, Lactobacilli and E. coli counts in ileal contents, but significantly increased Bifidobacteria counts and decreased E. coli counts in caecal contents. With the exception of significantly increased villus height in the ileum, the morphological measurements of the duodenum, jejunum, and ileum showed no response to dietary levels of inulin as compared with the control diet.In conclusion, the results from the current study suggest that feeding inulin may have a beneficial effect on intestinal microflora and morphology, and on the performance of broiler chickens.

“…These variations in response to AGPs between locations and studies were observed early after AGP use started (Braude et al, 1953). These early observations were confirmed by (Rosen, 1995) who analysed a massive database of more than 4 000 published reports from 55 countries and found coefficients of variation for the effects on weight gain and feed conversion in broilers and pigs of 110-199%, and coefficients of variation up to 705% for the effects on feed consumption.…”
