Recent research at this Institute has shown marked improvements in animal performance following the use of bacterial inoculants as silage additives (Gordon, 1989 and Mayne, 1990). Other studies with additives based on antimicrobial carboxylic salts (Maxgrass - BP Chemicals) have also shown large improvements in animal performance relative to untreated silage (Chamberlain et al, 1990). However with constraints on milk output in the form of milk quotas, it is important to investigate the potential “concentrate sparing” effect of these differing silage additives, whilst producing a constant yield of milk constituents.Five silages with a range of fermentation characteristics were produced by ensiling first regrowth herbage either untreated (C) or treated with four differing silage additives including: an inoculant of lactic acid bacteria (I); an inoculant of lactic acid bacteria plus enzymes (I+E); formic acid applied at 2.54 litres/t grass (FA) and antimicrobial carboxylic acids applied at 5.95 litres/t grass (CA).

Additive Treatment

When grass with an adequate content of fermentable substrate and epiphytic lactic acid bacteria is ensiled properly, the fermentation which follows is normally considered satisfactory. This fermentation can be altered by various categories of additive such as acids, sugars and inoculants, each of which can influence the fermentation differently. The experiment reported compared the fermentation products, aerobic stability and animal performance for silages made using formic acid or a Lactobacillus plantarum inoculant with well preserved silage made without additive treatment.A 42 day regrowth of Lolium multiflorum (cv. Lemtal) was harvested without wilting using two precision - chop harvesters. Alternate loads of grass were ensiled with (a) no additive, (b) formic acid (850g/kg) at 3.0 1/t or (c)inoculant (Ecosyl - ICI plc) at 3 1/t (separate harvester). The inoculant was constituted immediately before use and was applied in accordance with the manufacturers instructions. Harvesting was completed and the silos sealed within 26 hours of mowing. The silos were opened after 113 days.

Fermentation Quality

The efficiency of a novel strain of lactic acid bacteria inoculant (Lactobacillus plantarum VTT E-78076, E76) on the fermentation quality of wilted silage was studied. Furthermore, the possibility to improve aerobic stability of silages by combining an inoculant and chemical preservatives was investigated. Two experiments were conducted with wilted timothy-meadow fescue herbage (dry matter 429 and 344 g kg-1) using six treatments. In experiment I, E76 (106 cfu g-1 fresh matter (FM)) was applied alone and in combination with sodium benzoate (0.3 g kg-1 grass FM) or low rate of formic acid (0.4 l t-1 FM). In experiment II, E76 and a commercial inoculant were applied alone and in combination with sodium benzoate. Untreated silage and formic acid (4 l t-1 FM) treated silage served as negative and positive controls in both experiments. The effect of sodium benzoate and potassium sorbate in experiment I, on aerobic stability was tested by treating silages prior to aerobic stability measurements. The novel lactic acid bacteria inoculant was equally effective in improving fermentation quality as the commercial inoculant. However, the aerobic stability of both inoculated silages was poorer than that of formic acid treated or the untreated one in one of the experiments. The results suggested that antimicrobial properties of E76 were not effective enough to improve aerobic instability. One option to overcome this problem is to use chemical additives in combination with the inoculants.;

Silage Additives

The use of silage additives containing lactic acid bacteria and enzymes to promote a rapid homolactic type fermentation has met with some success in the United States but the little evidence available (see Burghardi, Goodrich and Meiske, 1980) suggests that, for grass silages, the value of this type of additive is limited. However, in laboratory silos, inoculation with lactic acid bacteria has been shown to be effective in reducing proteolysis (Carpintero, Henderson and McDonald, 1979).The recent availability in the UK of a commercial product containing a lactic acid bacteria inoculum and the non-toxicity and ease of application of this product prompted this investigation, which describes the assessment of a silage prepared with this type of additive in comparison with a well characterized additive, formic acid.

Microbial Groups

Four experimental silages were made into bunker silos by adding lactic acid bacteria and cellulase enzyme. The control silages were made without any additives and with AIV II solution (80 % formic acid, 2% orthophosphoric acid). The microbial compositions of the experimental silages were studied in five microbial groups; (1) total count of bacteria, (2) lactic acid bacteria, (3) Clostridia, (4) coliform bacteria and (5) fungi (yeasts and moulds). At the beginning of the fermentations enteric bacteria and lactic acid bacteria were increasing. Inoculation of the silage decreased the growth of enterobacteria compared with silages made with cellulase or without additives. This effect was further increased by using AIV II solution. Heterolactic fermentations started in the silages made with cellulase, inoculants and no additives, when initial reducing sugars, primarily glucose and fructose, were fermented. In good ensiling conditions only a few butyric acid forming Clostridia and small amounts of moulds and yests were found. Yeasts existed mostly in silages made with cellulase and with inoculation.
