“…Based on the data from the present study, the authors corroborate that, even with the use of inoculants, priority should be given to adequate handling of the silo face during unloading (Li & Nishino, 2011). Rodrigues et al (2015) also observed an increase in pH values in more advanced periods of silage use, given that the longer time of exposure to yeasts can contribute to greater consumption of lactic acid. Table 4 lists the summary of the analysis of variance of data relating to temperature, pH, dry matter and mineral content of corn silage treated with different inoculants, at different evaluated periods.…”

The objective was to evaluate the efficiency of two bacterial inoculants, 11CFT and 11C33, with different genera of lactic acid bacteria on the chemical and fermentation composition of the silage, and the temperature and pH behavior of the silage during the feed out period. The experimental design used was randomized blocks, with three treatments: corn silage without inoculant (control); corn silage with 11CFT inoculant (consisting of strains of Lactobacillus buchneri and L. casei); and corn silage with 11C33 inoculant (consisting of strains of L. buchneri, L. plantarum and Enterococcus faecium). The use of both inoculants increased the concentration of lactic acid in the silage (22.42 g kg-1 for control against 36.00 and 33.33 g kg-1 for 11CFT and 11C33, respectively) and reduced aerobic dry matter losses. The silage treated with 11C33 obtained a higher concentration of acetic acid (17.44 g kg-1) and propionic acid (2.08 g kg-1). The 11CFT inoculant provided a lower concentration of ethanol, however, without differing from the silage with 11C33 (0.70 and 1.61 g kg-1, respectively). Even without variations in temperature and pH at silage unloading, the use of the 11C33 inoculant generated a higher concentration of acetic and propionic acid, providing better aerobic stability days after unloading. Both inoculants also improved the in situ ruminal digestibility of corn silage compared to control silage. They provide an increase in the content of lactic and propionic acids, which assist to reduce dry matter losses and ethanol production. There were no variations in temperature and pH at the silo unloading, however, the use of the 11C33 inoculant generated a higher concentration of acetic and propionic acids providing better aerobic stability after exposure to air.

Inoculation of maize silage with Lactobacillus buchneri has improved livestock production in some cases, but the published literature has shown that results depend on the dietary forage: concentrate (F:C) ratio; however, there is little knowledge on the interaction between the silage inoculant and F:C ratio. Thus, we aimed to investigate the effect of feeding maize silage inoculated with L. buchneri NCIMB 40788 and two F:C ratios on feed intake and growth performance of lambs. Twenty-eight Dorper × Santa Ines lambs were arranged in a randomized block design (n = 7) and then assigned to one of four diets as follows: 1) untreated maize silage (with no silage inoculant) and low concentrate (400 g/kg dry matter (DM); US-LC); 2) maize silage inoculated with L. buchneri and low concentrate (400 g/kg DM; IS-LC); 3) untreated maize silage and moderately high concentrate (600 g/kg DM; US-HC); and 4) maize silage inoculated with L. buchneri and moderately high concentrate (600 g/kg DM; IS-HC). There was an interaction between inoculation and F:C ratio for DM intake (DMI), in which lambs fed the US-LC diet had lower DMI (P = 0.013) than that of all the other diets. Inoculation decreased crude protein (CP) digestibility (P = 0.003; -6.1%). As compared with the LC diet, the HC diet had a lower (P ≤ 0.016) apparent digestibility of DM, organic matter, and CP. Inoculation increased the average daily gain of lambs (P = 0.022) mostly when they were fed the LC diet than that observed for the HC diet. In conclusion, inoculation of maize silage with L. buchneri improved lamb production on feeding of diets having a higher proportion of silage, but this response was not accompanied of higher profitability. Additionally, the response of L. buchneri on lamb production is highly dependent of the F:C ratio.
