Embodiment 1

[0037] This experimental example is to implement the influence of a compound acidity regulator for silage on the fermentation quality of alfalfa silage and the influence of aerobic stability. The composition and weight ratio of the compound acidity regulator for silage are 60% propionic acid, 10% formic acid and 30% sodium benzoate. According to the composition and weight ratio of the above-mentioned raw materials provided by the present invention, the propionic acid is first accurately weighed and put into a stainless steel 316L reactor. 0 Slowly and evenly put sodium benzoate under the condition of C and the rotating shaft speed of the reactor at 200rpm, after fully dissolving and chemically reacting for 1-1.5h, add formic acid, continue dissolving, chemically react for 0.5-1h until the mixed solution becomes a homogeneous clear solution, That is, the compound acidity regulator product for silage of the present invention is obtained.

[0038] In this experiment, the alfalfa...

Embodiment 2

[0083] The composition and weight percentage of the compound acidity regulator for silage of the present invention are 65% of propionic acid, 30% of sodium benzoate and 5% of formic acid.

[0084] The physicochemical characteristics of the composite acidity regulator for silage that embodiment 1 and embodiment 2 make are: a. the density range is 1.05-1.16g / cm 3 ; b. pH The range is 3.2-3.5; c. 1% aqueous solution pH 3.5 + 0.2; 0.5% aqueous solution pH 3.6 + 0.2.

Embodiment 3

[0086] The composition and percentage by weight of compound acidity regulator for silage of the present invention are propionic acid 50%, sodium benzoate 25%, water 25%, and the physicochemical characteristic of the composite acidity regulator for silage obtained is: a. Density range is 1.02 -1.15g / cm 3 ; b. pH The range is 4.1-4.5; c.1% aqueous solution pH 4.0 + 0.2; 0.5% aqueous solution pH 3.5 + 0.2.

Abstract

The invention relates to a compound acidity regulator for a silage and a use method thereof. The compound acidity regulator is characterized by comprising the following components in percentage by weight: 50-65% of propionic acid, 5-10% of formic acid, 20-30% of sodium benzoate and 0-25% of water. The compound acidity regulator is used for acidity regulation of various silages, and the adding quantity of the compound acidity regulator in the silage is 2-5L / ton. According to the compound acidity regulator for the silage and the use method of the compound acidity regulator, the acidification process of the silage is accelerated, the period of the silage is shortened, the undesirable fermenting and secondary fermenting problems after cellar silage opening are prevented, nutrient substances of the silage are maintained to a maximal degree, the digestibility is improved, and the quality of the silage is improved, so that the improvement of milk yield of milk cows is accelerated and the fattening performances of beef cattle and mutton sheep are enhanced.

Description

technical field [0001] The invention relates to a compound acidity regulator for feed, in particular discloses a compound acidity regulator for silage and a using method thereof, belonging to the field of feed additives. The preparation of the present invention can be used as a silage additive, which can prevent the silage process from being affected by the type of raw materials, weather conditions, moisture content of raw materials, etc., accelerate the acidification process of silage and shorten the silage cycle, and prevent bad fermentation and secondary silage after the silage is opened. To solve the problem of secondary fermentation, preserve the nutrients of silage to the maximum extent, improve the digestibility and quality of silage, and then promote the increase of milk production of dairy cows and improve the fattening performance of beef cattle and mutton sheep. Background technique [0002] The successful preparation of high-quality and stable pasture and grain s...
