Feeding chickens in summer to reduce heat stress

Relieving heat stress is the key to raising chickens in summer. In production, in addition to taking measures to prevent heatstroke and strengthen feeding management, it is necessary to properly use some feed additives that can reduce heat stress.

Vitamin Vitamin C is the most reported anti-heat stress additive at home and abroad. It can reduce the death caused by heat stress and increase the egg production rate. Vitamin E has the function of protecting the cell membrane from oxidation and improving the body immunity. Prevention of heat stress has a certain effect; B vitamins also have a role in relieving heat stress, increasing growth rate, increasing egg weight and egg production. It has been reported that adding 100 to 150 mg of vitamin C per kilogram of feed at high temperatures can significantly increase eggshell thickness, reduce shelled eggs and shell eggs, improve eggshell color, and reduce bacterial infections; per kilogram feed The addition of 100-300 mg vitamin E has the effects of anti-stress, anti-oxidation, and promoting peripheral blood circulation, thereby reducing the chicken's stress sensitivity.

Zinc Bacitracin Zinc Bacillus Peptide is a heat stress reliever with good application effect. According to experiments, adding 100 mg of bacitracin zinc per kilogram of hen diet at a high temperature of 34°C can increase egg production by 5.4% and feed utilization by 5.8%.

Baking soda, namely sodium bicarbonate, has a stomachic and regulating blood acid-base balance. Adding 0.3% to 1% to the diet, or adding 0.1% to 0.2% of baking soda to drinking water, can significantly reduce heat stress.

Fumaric acid fumaric acid has a sedative effect. Adding 0.1% fumaric acid to feed can significantly relieve heat stress and increase appetite and promote weight gain.

In the heat stress of ammonium chloride, the body's heat dissipation increased, blood pH increased, and respiratory alkalosis was prone to occur. Appropriate amount of ammonium chloride in diet or drinking water can lower blood pH and relieve heat stress. According to reports, adding 0.2% to 0.3% ammonium chloride in drinking water can increase the weight gain by 10% to 23%.

The watermelon rind is chopped and the watermelon rind is chopped. Every day, the chicken is fed about 50 grams and fed three times. Feed it alone at noon, and feed it in the feed sooner or later. This can improve the heat resistance of the chicken.

In addition, supplementation of aspirin, selenium, tellurium, iodine, etc. in chicken diets can also reduce chicken heat stress.

Surgical Gown

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.
