Silage Inoculants

Aerobic spoilage of silages occurs frequently and is undesirable because it reduces both its nutritive and hygienic quality. Silage inoculants containing heterofermentative lactic acid bacteria, like Lactobacillus buchneri, have already been proven to improve aerobic stability by augmented production of acetic acid, which inhibits yeasts. In this study, the effect of L. buchneri on fermentation characteristics and aerobic stability of alfalfa-ryegrass silage, red clover silage and maize silage was assessed using microsilos. Two dosages, 1×105 and 3×105 cfu g-1 of fresh matter, were compared to untreated control silage. Inoculation with L. buchneri clearly altered the fermentation characteristics of alfalfa-ryegrass and red clover silage, resulting in a significantly higher aerobic stability at both dosages. The effects of L. buchneri inoculation on maize silage were less clear, but nevertheless the aerobic stability of maize silage inoculated with 1×105 cfu g-1 of fresh matter was significantly higher compared to the untreated silage.

AbstractHigh quality silage containing abundant lactic acid is a critical component of ruminant diets in many parts of the world. Silage deterioration, a result of aerobic metabolism (including utilization of lactic acid) during storage and feed-out, reduces the nutritional quality of the silage, and its acceptance by animals. In this study, we introduce a novel non-disruptive dual-sensor method that provides near real-time information on silage aerobic stability, and demonstrates for the first time that in situ silage temperature (Tsi) and pH are both associated with preservation of lactic acid. Aerobic deterioration was evaluated using two sources of maize silage, one treated with a biological additive, at incubation temperatures of 23 and 33 °C. Results showed a time delay between the rise of Tsi and that of pH following aerobic exposure at both incubation temperatures. A 11 to 25% loss of lactic acid occurred when Tsi reached 2 °C above ambient. In contrast, by the time the silage pH had exceeded its initial value by 0.5 units, over 60% of the lactic acid had been metabolized. Although pH is often used as a primary indicator of aerobic deterioration of maize silage, it is clear that Tsi was a more sensitive early indicator. However, the extent of the pH increase was an effective indicator of advanced spoilage and loss of lactic acid due to aerobic metabolism for maize silage.
