description | To improve the fermentation quality of silage and reduce the nutrients loss of
raw materials during the ensiling process, silage additives are widely used. The
effect of additives on silage is also affected by the species of crop.
Therefore, this study was designed to explore the effects of formic acid (FA)
and lactic acid bacterial inoculant on the quality of main summer crop silage.
The experiment was consisted on split-plot design with three replications. The
experiment used the main summer forage crops of proso millet
(“Geumsilchal”), silage corn (“Gwangpyeongok”), and
a sorghum-sudangrass hybrid (“Turbo-gold”). Treatments included
silage with Lactic acid bacterial Inoculant (Lactobacillus
plantarum [LP], 1.0 × 106 CFU/g fresh matter),
with FA (98%, 5 mL/kg), and a control (C, without additive). All silages were
stored for 60 days after preparation. All additives significantly increased the
crude protein content and in vitro dry matter digestibility
(IVDMD) of the silages and also reduced the content of ammonia nitrogen
(NH3-N) and pH. Corn had the highest content of IVDMD, total
digestible nutrients and relative feed value among silages. Compared with the
control, irrespective of whether FA or LP was added, the water soluble
carbohydrate (WSC) of three crops was largely preserved and the WSC content in
the proso millet treated with FA was the highest. The treatment of LP
significantly increased the lactic acid content of the all silage, while the use
of FA significantly increased the content of acetic acid (p
< 0.05). The highest count of lactic acid bacteria (LAB) was detected in
the LP treatment of corn. In all FA treatment groups, the total microorganism
and mold numbers were significantly lower than those of the control and LP
groups (p < 0.05). In conclusion, both additives
improved the fermentation quality and nutritional composition of the main summer
forage crops. The application of FA effectively inhibited the fermentation of
the three crops, whereas LAB promoted fermentation. So, both FA and LP can
improve the quality of various species of silage. |
