Bagacillo de caña (saccharum officinarum) predigerido por vapor a presión como alimento básico para novillos de carne

Al someter el bagacillo a altas presiones (18.3, 19.0, 19.7 y 20.4 kg/cm2) durante 4, 6, 8 y 10 minutos se incrementó significativamente la digestibilidad "in vitro" y la degradabilidad "in situ "de la materia seca. La aceptabilidad del bagacillo predigerido al vapor-BPOJ (O, 40, 60 y 85.42%) fue baja y se presentó disminución en el consumo y pérdidas de peso en novillos cebú que consumieron niveles por encima del 60%. No se observaron diferencias significativas (P and lt; 0.05) en la ganancia de peso promedio de novillos alimentados con BPDV y altos niveles de urea, usando una cantidad restringida de pasto rey (TI), bagazo crudo entero (T2) y melaza de caña (T3); la exclusión de fibra larga (T3) no afectó el desempeño animal. Se detectaron niveles de furfural por debajo del 1 % en el BPIN (base fresca); los análisis espectroscópicos (UV, RI, RMN) registraron la presencia de grupos carboxilos e hidroxilos, indicando la probable existencia de fenoles.De-rinded sugar cane bagasse (the pith) was subjected to high steam pressures (18.3, 19.0, 19.7 and 20.4 kg/cm2) during 4, 5, 8and 10 minutes. In vitro digestibilities and JD. situ degradabilities were significantly improved by the treatments. The steam pre-digested bagasse pith-SPBP (0,20, 40, 60 y 85.42%) acceptability were lowand the results showed very high weight losses of steers teed 60 and 80% SPBP of their diet. No statistical difference (P and lt; 0.05) was observed for average daily gains of steer fed on high levels of SPBP supplemented with high levels of urea, using three treatment: restricted amount of king grass (T1) whole raw bagasse (T2) and cane molasses(T3); the exclusion of the long fiber (T3) did not effect animal performance. Furfural levels below 1% SPBP (fresch basis) were detected; spectrometric analysis (UV, RI and FMN) registered the presence of carboxil and hidroxil groups indicating the probable existence of phenols

N-3 fatty acids in patients with multiple cardiovascular risk factors

BACKGROUND: Trials have shown a beneficial effect of n-3 polyunsaturated fatty acids in patients with a previous myocardial infarction or heart failure. We evaluated the potential benefit of such therapy in patients with multiple cardiovascular risk factors or atherosclerotic vascular disease who had not had a myocardial infarction. METHODS: In this double-blind, placebo-controlled clinical trial, we enrolled a cohort of patients who were followed by a network of 860 general practitioners in Italy. Eligible patients were men and women with multiple cardiovascular risk factors or atherosclerotic vascular disease but not myocardial infarction. Patients were randomly assigned to n-3 fatty acids (1 g daily) or placebo (olive oil). The initially specified primary end point was the cumulative rate of death, nonfatal myocardial infarction, and nonfatal stroke. At 1 year, after the event rate was found to be lower than anticipated, the primary end point was revised as time to death from cardiovascular causes or admission to the hospital for cardiovascular causes. RESULTS: Of the 12,513 patients enrolled, 6244 were randomly assigned to n-3 fatty acids and 6269 to placebo. With a median of 5 years of follow-up, the primary end point occurred in 1478 of 12,505 patients included in the analysis (11.8%), of whom 733 of 6239 (11.7%) had received n-3 fatty acids and 745 of 6266 (11.9%) had received placebo (adjusted hazard ratio with n-3 fatty acids, 0.97; 95% confidence interval, 0.88 to 1.08; P=0.58). The same null results were observed for all the secondary end points. CONCLUSIONS: In a large general-practice cohort of patients with multiple cardiovascular risk factors, daily treatment with n-3 fatty acids did not reduce cardiovascular mortality and morbidity.
