Embodiment 1

[0040] Example 1: Culture test of isolated bacteria using representative silage lactic acid bacteria

[0041] As a sugar source, prepare a mixture of mother liquor and molasses according to a mixing ratio (weight ratio) of 100:0-0:100, and add the mixture to 804 liquid medium (5g yeast extract, 5g peptone, 0.1g MgSO 4 ·7H 2 (2, 1000 ml of distilled water, pH 7.0), the reducing sugar concentration was adjusted to an amount corresponding to 0.5% by weight, and the lactic acid bacterium Lactobacillus plantarum (Lactobacillus plantarum) was subjected to liquid static culture at 30°C. The molasses used here is a by-product of sugar mills with a moisture content of 25-30% by weight and a sugar content of about 50% by weight.

[0042] As a control area, 804 liquid culture medium with a glucose concentration of 0.5% by weight was set. The details of mixing ratio and abbreviation are shown in Table 1.

Embodiment 2

[0050] Embodiment 2: Barley whole plant bottling silage test

[0051] Prepare the mixed solution of mother liquor and molasses according to the mixing ratio (weight ratio) of 80:20-20:80, add it so that it is 3% relative to the fresh weight of the whole barley plant of the material, and pack it into a 1L bottle (packing Bottle density 500g FW / L) carries out silage test.

[0052] Silage without mother liquor was prepared as a control area. The details of mixing ratio and abbreviation are shown in Table 2.

[0064] Embodiment 3: the culture experiment of the yeast that is isolated from silage

[0065] Prepare the mixture of mother liquor and molasses according to the mixing ratio (weight ratio) of 100:0-0:100, and add the mixture to PYG liquid medium (10g peptone, 5g yeast extract, 1000ml distilled water, pH 6.7-6.8) In the method, the reducing sugar concentration was adjusted to an amount corresponding to 0.5% by weight, and the silage yeast was subjected to liquid static culture at 30°C.

[0066] As a control area, a PYG liquid medium with a glucose concentration of 0.5% by weight was set. The details of mixing ratio and abbreviation are shown in Table 4.

Abstract

It is intended to provide a silage additive which improves silage fermentation and enriches livestock feeds at a low cost. Namely, a silage additive comprising a liquid by-product of amino acid fermentation having a pH value adjusted in an acidic region (3.0 to 6.0).

Description

technical field [0001] The present invention relates to the ability to multiply lactic acid bacteria in silage fermentation, enable long-term storage without impairing the quality of silage raw materials, suppress secondary fermentation (aerobic spoilage), improve digestibility, and have nitrogen components that are effective for livestock. A silage additive, and a silage preparation method using the additive. Background technique [0002] As roughage such as various pastures, feed crops such as wheat, corn, millet and feed rice, by-products of food production such as bean curd residue, sweet potato or potato starch residue, distiller's grains, and residues generated by the catering industry or food distribution industry, etc. The preparation of the storage and preservation method of silage is to block the air, form an anoxic state, and through lactic acid fermentation, its pH will drop sharply, inhibit the growth of aerobic bacteria in the initial stage of silage fermentati...
