Farm feed anti-fungal agent homemade technology
The antifungal agent for feed is a feed additive which can reduce the amount of microorganisms in the feed, control the metabolism and growth of microorganisms, inhibit the production of mycotoxins, prevent the loss of nutrients during the storage period of the feed, prevent the mildew of the feed and prolong the storage time. Can be divided into compound and unilateral two categories.
First, garlic feed mold 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.
Second, seaweed powder feed 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, acetic acid feed mold 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, orange peel feed mold 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 1-3% can significantly prolong the shelf life of the feed, and the feed will not be mildew even in rainy and humid weather.
Five, medicinal plant feed mold agent
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.
In metal cutting, hole processing is the most common process. In hole processing, drill drilling is the basic process.
When drilling, if the hole on the workpiece is very deep, carbide deep hole drills should be used at this time.
Specially used for processing deep hole drills, deep hole drills. In processing, holes with an aperture ratio greater than 6 are usually called deep holes. Due to the poor rigidity of the drill rod, it is difficult to remove heat and debris during deep hole drilling, and it is easy to bend and vibrate. Cooling and cooling systems are usually used to solve cooling and chip removal problems. In the automotive, mold and aerospace industries, deep hole drill bits are very popular.
