I. "Education", strengthening management, and strengthening resistance to disease
Satisfying the needs of pigs for various nutrients, improving pig house and sanitation are positive measures to prevent the occurrence of swine diseases. Feeds should be diversified and they must be properly matched and modulated. It is forbidden to feed moldy, degenerate feed, and forage grasses, so that coarse materials can be finely fed, regularly quantified, and less frequently added. It is not possible to change the feed abruptly, and the change of feed should be carried out gradually. Provide enough clean drinking water.
Second, "check", self-cultivation, strengthen quarantine
Self-cultivation is an important measure to prevent the spread of disease. If it is necessary to purchase breeding pigs or piglets from other places or markets, quarantine work must be done. The so-called quarantine work means that when you buy pigs from other places, you must first understand the occurrence of epidemics in the area, and you must go to pig farms where there are no infectious diseases.
Purchased pigs must be quarantined by local veterinarians and issue a quarantine certificate to prevent the injection of vaccine. Pigs that have just been purchased cannot be polycultured with the original pigs immediately. After one month of isolation and observation, when they are confirmed to be free of disease, they can be grouped together.
Third, "anti-", do a good job of preventive drugs and deworming
1, precautions should pay attention to the use of drugs: 1 before injection carefully check the bottle mouth and plastic cover is intact, the bottle of the drug name, batch number, validity period, etc. must be complete and clear. 2 The injection site should be sterilized with 75% alcohol cotton balls before injection. 3 The vaccine should be kept frozen. The diluted vaccine should be used within 4 hours.
2, regularly deworming. Deworming is an important measure for the prevention and treatment of parasitic diseases. It is necessary to rationally use insecticide-repellent drugs according to the prevalence of major parasitic diseases in the area and periodically deworm them.
Fourth, "eliminate", do a good job disinfection work
The eradication of pathogenic microorganisms in the external environment and the cut-off of infectious diseases are one of the effective measures to prevent the occurrence of epidemics. This article comes from the farm power network. Frequently clean the excrement in the pen, and clean the troughs and sinks. A large-scale detoxification is conducted once a year, and a small-scale disinfection is performed every season. Disinfection is a regular job. When disinfecting a pig house, pigs should be released first, and the feed, bedding, excrement, and dirt on the walls and ceilings should be removed and then sterilized. Disinfectant can use 20% lime milk, 3% fire alkali water, 5%~20% bleach, 0.5% potassium permanganate and so on.
Pigments are used for coloring paint, ink, plastic, fabric, cosmetics, food, and other materials. Most pigments used in manufacturing and the visual arts are dry colorants, usually ground into a fine powder. This powder is added to a binder (or vehicle), a relatively neutral or colorless material that suspends the pigment and gives the paint its adhesion.
Just because of the pigments, our world become colorful!
