Embodiment 1

[0032] A silage additive for maize silage, including raw materials of the following weight parts: 40 parts of Tara Single Ning, a mass fraction of 1.2%, the number of live bacteria is 1.3 × 10 9 CFU / ml of 20 parts of plant lactobacillus, 5 parts of meal acid, 10 neutral washing fibers, 6 of acidic washing fiber, 5 parts of water.

[0033] The preparation method of the silage additive is: expand the plant lactofam, and adjust the concentration of 1.3 × 10 9 CFU / mL then mixed with other components, under 35 ° C, 52 h, air-dried, air-dried, normal temperature conditions, to obtain a silage for corn silage. Additives.

Embodiment 2

[0035] A silage of silage for maize silage, including raw materials of the following weight parts: 50 parts of the mass fraction of 0.5%, 50 parts of the live bacteria, the number of live bacteria is 1.6 × 10 9 CFU / mL of 15 parts of Lactobacillus, 3 copies of meal acid, 15 neutral washing fibers, 7.2 parts of acidic washing fiber, 15 water.

[0036] The preparation method of the silage additive is: enlarged plant emulsion and adjust the concentration of 1.6 × 10 9 CFU / mL, then mixed with other components, under 37 ° C, 50 h was fermented with solid fermented, air drying, normal temperature conditions, to obtain a silage for corn silage. Additive.

Embodiment 3

[0038] A silage additive for corn silage, including the following weight parts: 45 parts of the mass fraction of 1.0%, 45 parts of Tarra, the number of live bacteria is 1.5 × 10 9CFU / mL of 20.9 servis, 4 parts of CFU, 4 parts of the food, 12.9 parts of neutral washing fiber, 7.2 parts of acidic washing fiber, 10 water.

[0039] The preparation method of the silage additive is: expand the plant lactofam, and adjust the concentration of 1.5 × 10 9 CFU / mL, then mixed with other components, under 36 ° C, 58h, solid fermented 48h, air dry, normal temperature conditions, to obtain a silage for corn silage. Additives.

Abstract

The invention relates to a silage additive for corn silage and application of the silage additive. Lactobacillus plantarum is matched with tara tannic acid, gallic acid, neutral detergent fibers and acid detergent fibers, so that the obtained silage additive has the advantages of reducing protein degradation and enhancing oxidation resistance; the problems that protein in corn silage is fast in degradation and large in loss, and the feed is poor in oxidation resistance are solved. The silage additive is good in effect when applied to corn silage, low in preparation cost, capable of being industrially produced and wide in application prospect.

Description

Technical field [0001] The invention belongs to the technical field of feed additives, especially a silage additive for corn silage and its application. Background technique [0002] Silage is a kind of roughage obtained by chopping green feed with a moisture content of 65%-75% and inhibiting the reproduction of various bacteria through the fermentation of anaerobic lactic acid bacteria under closed anoxic conditions. Mainly used to feed ruminants. Silage has become an excellent source of feed for livestock due to its good palatability, rich nutrition, and long-term preservation. [0003] Silage is a more cost-effective method of crushing silage raw materials for ensilage, ammoniation, kneading and micro-storage and then feeding livestock. This can not only save feed costs, but also allow the straw to be returned to the field through livestock manure, promoting a virtuous cycle in agriculture. High utilization. Currently commonly used silage raw materials include corn, ry...
