The principle of action and addition of sodium biacetate in silage anti-mildew preservation sharps

Feed grade sodium diacetate

As a feed additive, sodium biacetate is harmless to humans and animals, has no residue, good palatability, and has the function of increasing nutritional value and increasing feed quality. In addition, sodium diacetate is better than the current use of propionate.

In the natural state, sodium diacetate will slowly release acetic acid can effectively penetrate into the cell wall of mold tissue cells, interfere with the interaction of intercellular enzymes, can denature intracellular proteins, add sodium diacetate to feed can reduce water activity, make the bacteria protein denatured, by changing the cell morphology and structure to achieve the purpose of dehydration and death of the fungus, thus playing an antibacterial and anti-mildew role. Acetic acid is an important precursor to the synthesis of fats by ruminants. It is conducive to the formation of short-chain fatty acids in milk fat and increases the milk fat rate of milk.

Raising cows with the addition of 0.1%-0.15% sodium diacetate and silage can increase their feed intake by 10%-20%, milk production by 13%-20%, and milk fat rate by 0.2%. Feeding dairy cows, broilers and piglets with 0.1%-0.2% sodium diacetate can increase weight gain by 6%-10%, feed conversion rate by about 10%, and increase the survival rate of poultry in the brooding stage by 10%.

Antifungal effect of sodium diacetate

Sodium diacetate has a strong ability to kill mold and is best used to inhibit grain mildew. According to the literature, in the grain with a moisture content of 21.5%, 0.1% to 0.8% of sodium diacetate is added, the storage period can be extended from 90 days to 280 days, and O.5 to 1.0% of the sodium diacetate containing 77.6%, sorbitol 20% and anti-caking agent 2.4% of the compound mold growth inhibitor is added to the grain with a moisture content of 17% to 33%, and the mold formation is not seen for 90 days under the conditions of 21 to 27 °C and humidity 70% to 85%. Adding 0.75% sodium diacetate to grains with a moisture content of 22% is 20 times more resistant to mildew than without sodium diacetate.

Sodium diacetate added to the silage, can effectively inhibit the growth of mold, improve the quality of silage, to achieve the purpose of preservation, in the silage added 0.2% ~ 0.4% sodium diacetate, can make the silage in pH = 4.08 when the storage period of more than 3 weeks. According to Ge Zhenghua (1993), about 0.2% of the SDA was added to the silage ryegrass, and after 150 days of storage, the total number of molds in the experimental group was only 10% of the control group, and it was basically not moldy during the use period.
