Adding garlicin to feed can improve meat quality
Allicin is a kind of feed additive that has been widely used in recent years. Due to its characteristics of safety, cheapness, greenness, non-toxicity and no residue, it has been favored by the majority of farmers, adding proper amount of allicin to the growth of pigs in the diet. There is an inestimable effect.
Allicin contains natural garlic oil with a strong garlic odor. Allicin oil is mainly composed of diallyl disulfide and diallyl trisulfide. The total content is greater than or equal to 80%. It has strong bacteriostasis. It causes diarrhea and diarrhoea caused by Shigella, Salmonella typhi, and Pasteurella. Pneumonia and bronchitis have a significant effect. Allicin has a pure and natural strong aroma, which can replace other flavoring agents in the feed. Adding 50ppm~150ppm allicin to the feed can improve the feed odor, stimulate the pigs to produce a strong attractant effect, and increase appetite greatly. The feed intake also increases, which in turn increases the net weight.
The physical and chemical properties of allicin depend mainly on garlic oil, which is a pale yellow to red-brown liquid with a density of 1.050 to 1.095 and a refractive index of 1.550 to 1.580. It is soluble in most non-volatile oils, partially soluble in ethanol, insoluble in water, glycerol and propylene glycol, etc. . Enormous acid, strong oxidants, and UV light can cause deterioration.
Adding allicin to the piglet diet can improve the aroma and quality of the meat. To make the scent thicker, the method of adding allicin to the feed is simple and easy, as long as the garlic is soaked, sliced, dried (or dried), and then crushed. Volatile sulfur compounds in allicin can drive mosquitoes and moths to suck up feed and feces. Allicin is converted into allicin by enzymes in the pig's body. After entering the pit with the urine, it can stop mosquitoes and mosquitoes. Propagation in urine and larvae, reduce the harassment of animals by mosquitoes and flies, reduce disease transmission, and improve the surrounding environment.
The addition of allicin can maintain the basic flavor of the original feed, although it will release a special odor, but a lot of test results show that pigs prefer the smell of garlic. In a diet of 20-day-old, healthy and disease-free Du Chang-Cheng dual-hybrid weaned pigs, 25% of allicin was added to 200 grams per ton. Antibiotics were added to the control group. The results showed that compared with the control group, the daily allicin group was added. The weight gain increased by 16.5%, the feed weight ratio decreased by 13%, and there was no significant difference in feed intake, indicating that allicin has a role in promoting growth of the sow. Allicin can significantly increase weight gain and improve feed remuneration.
Allicin can also be used to control many swine diseases such as tsutsugamushi disease, tsutsugamushi disease, paratyphoid fever, gastroenteritis, rheumatism and tetanus.
In summary, the addition of allicin to the pig's feed is an effective method to prevent environmental pollution and promote the development of the aquaculture industry. It has broad prospects for development and application.
Medical protective masks refer to self-priming filter dustproof medical protective equipment that can filter particles in the air, prevent the spread of certain infectious microorganisms in the respiratory tract, and block droplets, blood, body fluids, secretions, etc.
Medical protective masks are masks made of one or more fabrics that have isolation effects on viral aerosols, virus-containing liquids, and so on. Under the respiratory airflow, it still has a barrier effect on viral aerosols, virus-containing liquids, etc., and when removed, the outer surface of the mask does not contact the human body, can filter particulates in the air, and block droplets, blood, body fluids, secretions, etc. . The use of medical masks includes adhesion testing, training, model selection, medical treatment and maintenance.
Composition and function: The Medical Protective Mask consists of a mask face and a tightening belt. The mask face is divided into three layers: inner, middle and outer. The inner layer is ordinary sanitary gauze or non-woven fabric. Propylene fiber melt-blown material layer, the outer layer is non-woven fabric or ultra-thin polypropylene melt-blown material layer. This high-efficiency medical Protective Mask is highly hydrophobic and breathable, and has a significant filtering effect on tiny virus-carrying aerosols or harmful fine dust, and the overall filtering effect is good.
The medical protective mask has a good fit with the wearer's face, can filter particles in the air, block pollutants such as droplets, blood, body fluids, secretions, etc., and can filter non-oily particles by more than 95% Personal protective equipment commonly used to deal with airborne diseases.
Product specifications: According to the national standard GB 19083-2003 "Technical Requirements for Medical Protective Masks", important performances of medical protective masks include filtration efficiency, adhesion, liquid barrier performance, comfort, hygiene, and biological safety tests.
Scope of application: Medical protective masks are better protective products. It is recommended to wear when there is serious environmental pollution or sudden medical infectious diseases (such as respiratory tract infectious diseases), to prevent the spread of viruses from patients or the environment to users.
Important indicators: including non-oily particle filtration efficiency and airflow resistance.
(1) Filtration efficiency: Under the condition of air flow (85 ± 2) L / min, the filtration efficiency of aerodynamic median diameter (0.24 ± 0.06) μm sodium chloride aerosol is not less than 95%.
(2) Tightness: The overall fit factor of the mask should not be less than 100.
How to use: How to wear a head mask
(1) Gently pinch the nose clip and place the mask on the face to ensure that it can cover the nose and mouth.
(2) The upper elastic band is fastened on the head to prevent air from entering.
(3) Tighten the lower elastic band around the neck.
(4) Be sure to fully open the mask to minimize the number of layers used during breathing.
How to wear earhook masks
(1) Pass the ear straps with both hands, place the nose clip on the upper part, and wear the mask on the nose and mouth
(2) The ear strap should be placed at the base of the ear and spread from head to toe, so that the folds of the mask are fully unfolded, which helps to cover the face to the greatest extent and minimize the number of layers required for breathing.
(3) Gently pinch the nose clip to prevent air from entering.
