How to make a yellow feed
1. The corn stalk was crushed with a crusher. When the corn stalk is crushed, the length of the crushed straw must be no more than 10 cm, and it can be crushed by the knuckles of the straw and become soft.
2. Spray the comminuted straw with water and compound inoculum. The compound bacteria agent is generally added to the water and sprayed with a sprayer after stirring. The amount of water spray is based on the humidity of the straw. Generally, the water content of the straw is required to be between 60% and 70%. While spraying water, pay attention to stir the straw so that the water content is even.
In addition, it should be noted that when the straw is sprayed, it must be pressed in a timely manner. After a long time, the moisture penetrates into the straw, and the water content will generally exceed the requirements. The resulting yellow silage tends to become sour or has an unpleasant smell, affecting feeding. effect. If the briquetting is done in time, even if the straw has a large moisture content, the excess water will be squeezed out during the briquetting and the effect on the quality of the yellow feed will not be too great.
3. The stirred crushed straw was loaded into the compactor box for compaction.
4. Bundle the blocks. Open the lid on the four sides of the container first, bundle the material block with two plastic ropes, and lift the hydraulic cylinder to relieve pressure. Note that the plastic rope should not be tied too tightly so as to prevent the plastic rope from breaking after pressure relief. After the pressure relief material is pushed out of the material box, the fifth step of the bagging operation can be performed.
5. Bagging operation. Each block has about 100 kilograms and it is very laborious to move. When bagging, the bag is first set on the block from top to bottom, and then the block is turned one by one, and the bag can be bound. Pay attention to the bag when the two sets of layers, a plastic bag inside, coat a layer of plastic woven bag. Strapping bag must be bundled and strong, do not air.
6. Weigh and mark the bagged bag. The content of the tag. It is generally necessary to mark the weight of the block, the date of manufacture, the condition of the additive, and the like. This information is mainly used to understand the condition of the blocks during feeding, and it is also possible to accumulate production experience in order to produce better yellow rations.
7. The last step is palletizing storage. When storing pallets, choose a local palletizing system that is easy to shelter from the sun and is not easily invaded by other animals. Although the yellow stored material is not afraid of freezing and is not afraid of rain, it is easy to breed lactic acid bacteria in areas where it is sheltered from the sun, which is beneficial to silage. Cured."
Usually about 1 month can be finished yellow feed, you can open the bag feeding.
The benefits of processing the yellow feed
The social and economic benefits of yellow storage are very significant. First of all, it solved the dangers of fire hazards where straws were stacked and reduced the storage space. Second, the utilization rate is improved compared to feeding dry straw. The feed rate of dry straw generally fed can only reach about 70%, especially in the roots and segment sections of corn stalks. Even if silage is used, if the silo is used, the silage at the bottom and edge of the pit will be used. The material is prone to mildew, and its utilization rate is only about 70%. The utilization rate and feed intake of yellow feed can reach almost 100%. Third, the nutritional value of the silage is almost the same as that of silage, and it has the effect of appetizing and increasing appetite, which can increase the milk production of dairy cows and enhance the physique and disease resistance of livestock.
How to identify the quality of the yellow feed
Identification of the quality of the yellow feed:
One must watch it. Good yellow stocks are brightly colored, generally yellow or with green leaves; poor yellows are dark in color, grayish or dark in color.
The second is to smell it. Good yellow storks have a stronger fruit scent, a bit like the taste of wine; poor yellow berry scent is not strong, and some are accompanied by sourness or other odors.
The third is the feel. Good yellow stocks have a soft texture and moderate moisture; poor yellows have a hard or sticky feel.
Surgical gowns, as necessary protective clothing during the surgery, are used to reduce the risk of medical personnel coming into contact with pathogenic microorganisms, and can also reduce the risk of pathogenic microorganisms spreading between medical staff and patients. It is a safety barrier for sterile areas during surgical operations .
* Scope of use of surgical gowns: can be used for surgical operations, treatment of patients; anti-epidemic inspection in public places; disinfection in virus-contaminated areas; can also be widely used in military, medical, chemical, environmental protection, transportation, epidemic prevention and other fields.
* Classification of Surgical Gown
1. Cotton surgical gown. Medical institutions are the most widely used and most dependent surgical gowns. Although they have good breathability, they have poor barrier protection. The cotton material is prone to shedding of flocs, so that the annual maintenance cost of the ventilation equipment of the hospital will also have a large burden.
2. High density polyester fiber fabric. This type of fabric is mainly composed of polyester fiber, and conductive materials are embedded on the surface of the fabric, so that the fabric has a certain antistatic effect, thereby improving the comfort of the wearer. This kind of fabric has certain hydrophobicity, it is not easy to produce cotton de-flocking and the advantages of high reuse rate. This kind of fabric has good antibacterial effect.
3. PE (polyethylene), TPU (thermoplastic polyurethane elastic rubber), PTFE (teflon) multi-layer laminating film composite surgical gown. The surgical gown has excellent protection performance and comfortable breathability, which can effectively block the penetration of blood, bacteria and even viruses. But the popularity in China is not very wide.
4. (PP) polypropylene spunbond fabric. Compared with the traditional cotton surgical gown, the appearance of this material is because of its low price, and has certain advantages such as antibacterial and antistatic, so it can be used as a material for Disposable Surgical Gowns, but the ability of this material to resist hydrostatic pressure is relatively Low, and the blocking effect of the virus is relatively poor, so it can only be used as a sterile surgical gown.
5. Water spur cloth composed of polyester fiber and wood pulp. Generally only used as a material for disposable surgical gowns.
6. Polypropylene spunbond-meltblown-spun. Adhesive composite non-woven fabric (ie SMS or SMMS): This material is a high-quality product of a new type of composite material. Hydrostatic pressure capacity. SMS non-woven fabrics are widely used at home and abroad, often used to make high-grade surgical gowns.
* Structural design of surgical gown
New protective surgical gown
By providing a protective collar, the neck of the operator can be kept warm. By setting a hand guard pocket, it is helpful for the operating staff to temporarily put their hands in the hand guard pocket while waiting during the operation, which plays a protective role, and is more in line with the principles of aseptic operation and occupational protection.
By setting the contraction cuff, it is helpful to fit the cuff to the wrist, prevent the cuff from loosening, and prevent the glove from slipping out during the operation, which may expose the operator's hand to the glove.
The design of the new humanized protective surgical gown has been improved in the key areas of the surgical gown. The two areas of the forearm and chest area are double thickened, and there are hand pockets in front of the chest and abdomen. By setting reinforcement tablets (double-layer structure) in key areas, it is helpful to improve the ability of surgical gowns to resist water permeability and improve safety.
* Performance of surgical gown
The performance of surgical gown mainly includes: barrier performance, comfort performance.
1. Barrier performance mainly refers to the protective performance of surgical gowns. Its evaluation methods mainly include hydrostatic pressure, water test, impact penetration, spraying, blood penetration, microorganism penetration and particle filtration efficiency.
2. Comfortable properties include: breathability, water vapor permeability, drape, quality, surface thickness, electrostatic properties, color, reflectivity, odor and skin sensitization, and the effects of design and sewing in garment processing. The main evaluation indicators are air permeability, moisture permeability and charge density.
* Why is the surgical gown green?
In the operating room, if doctors, nurses and other staff wear white coats, because the doctors always see bright red blood stains during the surgery, for a long time, occasionally turning their attention to the companion's white coat You will see spots of "green blood stains", which will confuse vision and affect the surgical effect. The use of light green fabric for surgical gowns can not only eliminate this green illusion due to visual complementary colors, but also reduce the fatigue of the doctor's optic nerve, thereby ensuring the smooth operation of the operation.
