Feeding quantity of piglets at the time of weaning has a great influence on their growth and development. If they are fed too much, they can easily cause gastrointestinal diseases such as indigestion and diarrhea. If there is insufficient feeding, stress response due to hunger will affect growth. Therefore, 4 to 5 days after weaning, we must restrict feeding and feed less. Timing is controlled at about 70% of the original diet, and each feeding amount can be flexibly controlled according to the following conditions.
According to the feed intake of the piglet, the piglet must first look at the feed situation in the feed tank. If there is only a little scraps of foam in the tank, it means the amount of feed last time is moderate; if you see the feed tank is being cleaned and moistened , indicating that the amount of feed last time is insufficient, the amount of feed should be increased this time; if there is more leftover material in the tank, it means that the amount of feed last time is too much, this time it should be reduced. Take care to remove the leftovers.
According to the defecation status of the piglet, the feces of the piglet within 3 days after weaning are thickened and become brown, which is normal feces. If the feces is soft, the oil shines, the color is positive, and the feeding amount does not need to change; if there is sporadic feces in the circle, there are feed pellets, indicating that some pigs have overslaught, and the feeding should be reduced by about 20% from the previous time; If the feces is found to be paste-like, light grey, and sporadic yellow, the feces contain undigested feed. This is a sign that the whole litter of piglets will be squatting and should stop eating. The next meal can only be fed 1/2 , It depends on the situation. If you see most of the feces in the circle become soft and dark, the amount of feed can be restored to 80% of the normal amount, and then the next dose can be restored to the normal amount if the stool is mushy and green. , fecal mixed with falling out of the intestinal mucosa, etc., to stop two meals, the third meal only in the bottom of the tank sprinkle a small amount of feed, gradually increase the amount of feed, and then gradually returned to normal after 3 days.
According to the piglet's activity, the piglets before they feed hear the sound of buzzing in front of the trough, and the calls are continuous, indicating that hunger can be fed more feed; feeding about 10 minutes, the feed in the trough is taken out, the piglet does not return to the nest, in the trough Looking at the crowded side of the road, it shows that there is insufficient material and you can cast some more. If the piglet does not hear the sound before feeding, it will not reach the edge of the trough. The sound of the piglet is small and weak, and it is not to panic. It means that you are not hungry and you can use less material.
After the piglets are weaned, during the feed restriction stage, the feed model must be kept in line with the lactation period to ensure adequate and clean drinking water and immunization. Houses should be regularly sterilized and kept dry and hygienic.
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.
