First, the use of orange peel feed anti-fungal agent. Take fresh citrus peel or dried citrus peel and put it into a solution of methanol, ethanol, ether or acetone. The amount of the solution is 3-6 times the volume of the orange peel dry matter, and it is extracted at room temperature or by heat treatment, and then used. By distillation or the like, the organic solvent in the extract is removed, and an orange-yellow viscous concentrate having an anti-mildew effect is obtained, which is a feed anti-fungal agent. Adding it to the feed in a ratio of 1% to 3% can significantly prolong the shelf life of the feed, and the feed will not be mildew even in rainy and humid weather.
Second, the use of seaweed powder to make feed anti-mold agent. Mixing 92% seaweed powder, 4% calcium iodate and 4% calcium propionate uniformly becomes a highly effective feed anti-fungal agent. It is added to the feed in an amount of 8%. After being placed at a temperature of 30 ° C and a relative humidity of 100%, the feed will not be mildewed and deteriorated for one month, ensuring safe storage and increasing The iodine content in the feed.
Third, the use of acetic acid feed anti-fungal agent. After mixing acetic acid and sodium acetate in a ratio of 2:1, 1% sorbic acid or alkyl propionate is added, and the mixture is thoroughly stirred and dried to form a feed antifungal agent. If it is added to 1% of the weight of the feed, the feed can be stored for more than 90 days in any season and will not be mildewed.
Fourth, the use of garlic feed anti-fungal agent. Peel the garlic out of the skin, put it into a sterilized mortar, add the same amount of cold water, grind it into a fine pulp, and filter it through a 3-layer sterile cloth. The filtrate is an excellent feed anti-fungal agent. If it is evenly mixed into the feed at a ratio of 3%, it will not only prevent the mold from being moldy, but also prevent the intestinal diseases of livestock and poultry.
5. Feeding mold inhibitors with medicinal plants. Take medicinal plants such as Atractylodes lancea L., Artemisia argyi, Pyrethrum, etc., and dry it into a powder to inhibit the growth of mold. If added to the feed at 4%, the safe storage period of the feed can also be extended.
