          Abstract

          RESUMEN El objetivo del estudio fue evaluar el uso del ensilaje líquido de banano orito con tubérculos de taro en la dieta de cerdos en posdestete. En el experimento 1 se preparó un total de 30 microsilos de 1 kg de capacidad y se determinaron indicadores físicos, microbiológicos, organolépticos y químicos a los 1, 4, 8, 15, 30 y 60 días de fermentación (cinco en cada día). En el experimento 2 se emplearon 60 lechones castrados Landrace x Duroc x Pietrain de 8.53 ± 0.28 kg, distribuidos en tres grupos con 20 animales cada uno y alimentados con 0, 2 y 4% de inclusión de ensilaje en la dieta. El ensilado en el día 1 presentó la mayor temperatura (22.56 ºC) y pH (4.82). No hubo presencia de Escherichia coli, Clostridium spp o Salmonella spp. El olor (dulce fermentado), color (verdoso claro) y consistencia (pastosa) del ensilado fue adecuado. Además, presentó un buen tenor de materia seca, materia orgánica, proteína, extractos libres de nitrógeno, energía bruta, energía digestible, energía metabolizable y bajos niveles de cenizas, grasa y fibra. La inclusión de ensilaje líquido de banano orito con tubérculos de taro en la dieta de cerdos en posdestete al 2 y 4% mejoró el consumo de alimento, ganancia de peso, conversión alimentaria, peso final y redujo la incidencia de diarreas en los animales.

          ABSTRACT The aim of this study was to evaluate the use of liquid silage of baby banana with taro tubers in the diet of post-weaning pigs. In experiment 1, 30 microsilos of 1 kg capacity were prepared and physical, microbiological, organoleptic and chemical characteristics were determined at 1, 4, 8, 15, 30 and 60 days of fermentation (five per day). In experiment 2, 60 Landrace x Duroc x Pietrain castrated piglets of 8.53 ± 0.28 kg were used, distributed in three groups with 20 animals each and fed with 0, 2 and 4% silage inclusion in the diet. The silage on day 1 had the highest temperature (22.56 °C) and pH (4.82). There was no presence of Escherichia coli, Clostridium spp or Salmonella spp. The odour (fermented sweet), colour (light greenish) and consistency (pasty) of the silage was adequate. In addition, it presented a good content of dry matter, organic matter, protein, nitrogen-free extracts, gross energy, digestible energy, metabolizable energy and low levels of ashes, fat and fibre. The inclusion of 2 and 4% liquid silage of banana orito with taro tubers in the diet of post-weaning pigs improved feed consumption, bodyweight gain, feed conversion, final body weight and reduced the incidence of diarrhoea in animals.

              Silage microbiology and its control through additives

              Ensiling is a method of preserving a moist crop. A moist crop can support the growth of a wide range of microorganisms, most of which will degrade the nutrient value to livestock. However, ensiling generally controls microbial activity by a combination of an anaerobic environment and a natural fermentation of sugars by lactic acid bacteria on the crop. This fermentation and the resulting low pH primarily suppress the growth of other anaerobic microorganisms. The fermentation can also inhibit yeasts, molds and aerobic bacteria, but the anaerobic environment is essential to preventing most of the spoilage microorganisms from growing. Inoculants have become the dominant additives for making silage. Homofermentative strains help guarantee a rapid suppression of anaerobic stains early in storage, increase dry matter recovery and have improved animal performance by means that we do not fully understand. Inoculants containing Lactobacillus buchneri, a heterofermentative species capable of fermenting lactic acid to acetic, are recent additives. The added acetic acid inhibits yeast and mold growth, increasing aerobic stability of silages at feeding.
