Fermentation and aerobic stability of corn silage inoculated with Lactobacillus buchneri

Abstract

-The characteristics of fermentation and aerobic stability were evaluated in corn silage inoculated with different doses of Lactobacillus buchneri. The whole corn plant (300 g/kg DM) was ensiled in quadruplicate laboratory silos (7L). L. buchneri 40788 was applied at 5×10 4 , 1×10 5 , 5×10 5 and 1×10 6 cfu/g of fresh forage. Silages with no additive were used as controls. After 130 d of ensiling, the silages were subjected to an aerobic stability evaluation for 12 days, in which chemical and microbiological parameters as well as the temperature of the silage were measured to determine the aerobic deterioration. The addition of L. buchneri resulted in increased acetic acid concentrations. The number of yeast colonies was low in all treated silages. The pH, lactic and propionic acid concentrations did not differ between silages. Under aerobic conditions, all the treated silages showed a low number of yeasts and a great aerobic stability. Therefore, L. buchneri is effective against yeasts and improves the aerobic stability of corn silage in laboratory silos. However, doses equal or superior to 1×10 5 cfu/g of fresh forage were more efficient in the control of aerobic spoilage.

“…According to the evidence that silages inoculated with homofermentative LAB will deteriorate faster following aerobic exposure . Our results in the present study support the findings of Hassanat et al The pH of L silage increased gradually with the time of aerobic exposure which might be attributed to lactic acid was consumed by yeasts during aerobic exposure . M silage showed the similar pattern with L silage in terms with lactic acid content and pH value variations, while M silage delayed the aerobic deterioration time than L silage.…”

“…Despite the high dry matter content of silages (Table 2), the specific mass obtained with the compaction in the preparation of these (Table 1) is a relevant factor, favoring post-opening conservation along with the use of the additives. Increase in the silage pH with the days of exposure was also verified by Basso and Bernardes et al (2012), with a variation from 3.95 on the day of opening the silos to 5.67 on the 12 nd day of exposure. The increase in pH after silage exposure to air is an important indicator of silage deterioration.…”
