Inoculation of Lactobacillus plantarum for fermentation and conservation of corn silage

In order to evaluate the effect of L. plantarum inoculation on the fermentation, conservation and quality of corn silage (Zea mays), 32 bags with forage were used to produce silage at different doses of L. plantarum inoculation (0, 5, 10, 15 ml) and sampling times (15, 30, 45 days), in a completely randomized design. The pH, temperature and colony forming units (CFU) were studied. In addition to the bromatological characteristics, the sampling time was significant (p<0.01) for the pH, with the lowest average value (3.65) at 30 days. A higher temperature (27oC) was observed after 15 days of sampling (p<0.01). The application of L. plantarum in the bromatological components did not have a statistical impact except for the dry matter where T3 at 15 days presented the highest average (23.65%). Besides, the maximum average values were for raw protein (10.71%) in T2 at 30 days; ethereal stratum (2.36%) in T1 at 45 days; raw fiber (37.30%) in T3 at 45 days; ash (9.28%) in T2 at 30 days and digestible energy (2.41 Mcal/Kg) in T2 at 15 days. It is concluded that microbial inoculation makes it possible to accelerate the forage conservation process.
