There is a lot of rain in summer, and it is necessary to prevent mildew from preserving the feed. The method of preserving feed in summer is as follows:
1. Anoxic and mildewproof method. The feed is sealed and stored in a plastic bag, and the microbial respiration is used to cause hypoxia in the bag, thereby inhibiting the growth of the mold.
2, calcium propionate (sodium) anti-mildew method. 100 grams of calcium propionate was added per 100 kg of feed. The method is: first stir a small amount of feed with propionic acid (sodium), then add a large amount of feed, mix it evenly and store it in a dry cement pool or plastic bag. This method can prevent mildew for more than 100 days.
3. Dry anti-mildew method. The warehouse where the feed is kept must be dry. The bottom of the feed should have a bottom of 15-20 cm high, leaving a gap between the top and the surrounding to keep the air clear.
4, acetic acid anti-mildew method. Mix 2 parts of acetic acid and 1 part of sodium acetate, add 1% sorbitol, stir well, dry and mix into the feed at a ratio of 1%. This method can ensure that the feed is not moldy for 2 months.
