Problems solved by technology

However, at present, there are no in-depth reports on the utilization of grain amaranth in silage, and there are only a few basic experimental studies.
And in the existing reports, the application of microbial additives is not involved, and the preparation method of grain amaranth silage is still a traditional silage method, with low production efficiency and short shelf life, which is not conducive to storage and transportation.

Embodiment 1

[0068] Example 1 Compound microbial silage additive

[0069] A composite microbial silage additive includes enzyme bacteria complex and amaranth root extract. The mass ratio of the enzyme bacteria complex and the amaranth root extract is 1:2-2:3.

[0070] Wherein, the ratio of enzyme to bacteria in the enzyme-bacteria complex is 1:1-3.

[0071] The enzymes in the enzyme bacteria complex include one or more of cellulase, hemicellulase, amylase, pectinase or protease; the amylase is glucoamylase, α-amylase, β -Amylase, pullulanase or isoamylase.

[0072] The bacteria in the enzyme-bacteria complex are mainly lactic acid bacteria group, and also include several types of bacillus group, photosynthetic bacteria, yeast group, actinomycete group or filamentous bacteria group, with a total of 80-90 kinds of microorganisms.

[0073] Among the bacteria in the enzyme bacteria complex, the mass percentage of the lactic acid bacteria group is 70-90%.

[0074] The lactic acid bacteria group includes ...

Embodiment 2

[0085] Example 2 Grain amaranth silage

[0086] 1. A grain amaranth silage, the preparation method of the grain amaranth silage is as follows:

[0087] S1. Harvesting and crushing: Grain amaranth is harvested at the initial flowering stage, when the nutrient accumulation is the highest, it is rolled by a roller and combined with longitudinal cutting to make it into 1.0-2.0cm pieces (for cattle and sheep and other livestock, it is appropriate to cut 2.0cm in length; For feeding poultry and fish such as chickens, ducks, etc., cut 1.0cm length is appropriate);

[0088] S2. Add compound raw materials (filling materials): add corn stalks in the ratio of grain amaranth: corn stalks = 7:3~6:4, and control the moisture content to 65~75% to obtain a mixture;

[0089] S3. Adding additives: Take the composite microbial silage additive of Example 1, and dilute it at a ratio of 1:50-100, and then add 1L per ton of silage raw materials to spray the composite microbial silage additive in the mixing ...

Embodiment 3

[0098] Example 3 Grain amaranth silage

[0099] 1. A grain amaranth silage, the preparation method is the same as that in Example 2, except that the corn stover in step S2 is replaced with 10-15% bran.

Abstract

The invention discloses a compound microorganism silage additive and an application to preparation of grain amaranth silage. The compound microorganism silage additive comprises an enzyme and bacteria compound and an amaranth root extract, enzyme in the enzyme and bacteria compound comprises cellulase, hemicellulose, amylase, pectinase, protease and the like, bacteria in the enzyme and bacteria compound comprise a lactobacilli flora, a bacillus thuringiensis group, photosynthetic bacteria, a yeast flora, an actinomycete group, filamentous bacteria and the like, and main components of the amaranth root extract include plant sterol, polysaccharide, oleanolic acid, flavonoid, triterpenoid saponins, organic acid and the like. Compared with a conventional silage additive, the compound microorganism silage additive is good in fermentation effect and palatability. The grain amaranth silage is prepared from the compound microorganism silage additive, the potential advantage of raw materials serving as green feed can be effectively improved, daily gain can be remarkably increased, feed-meat ratio is increased, animal growth is promoted, and the grain amaranth silage can be widely used for livestock and poultry breeding and aquaculture.

Description

Technical field [0001] The invention belongs to the technical field of animal nutrition and feed. More specifically, it relates to a composite microbial silage additive and its application in the preparation of grain amaranth silage. Background technique [0002] With the continuous improvement of our people's living standards and the continuous advancement of urbanization, domestic cattle and sheep and other herbivorous livestock production has achieved unprecedented development, and the growth rate of domestic beef and mutton consumption has further accelerated along with the advancement of urbanization. Relevant data show that the supply of beef and mutton in my country is seriously insufficient. One of the main reasons is that the supply of high-quality roughage is seriously insufficient, which leads to poor health of livestock, high feeding costs and low economic benefits. [0003] Silage is one of the most important roughages for ruminants such as cattle and sheep in our cou...
