Dairy Farm Community Disinfection Frequently Asked Questions

In recent years, with the establishment of dairy farming communities, people have paid more and more attention to the prevention of dairy cow diseases. However, some dairy farming communities have misunderstood the daily disinfection work and lack scientific guidance. Please see the common problems in the cattle community:

Disinfection of cattle-raising districts that are not sterilized by disinfecting procedures should not be arbitrarily done and should follow certain procedures. Choose disinfectants that are safe to humans, cattle and the environment, have no residual toxicity, are not destructive to equipment, and do not produce harmful accumulations in cattle. Different disinfectants should be used for different disinfection targets and different disinfection methods should be adopted, such as cowsheds, cattle roads, vehicles available hypochlorite, and benzalkonium disinfectants for spray disinfection. Special attention should be paid to the disinfection of cattle body. Before operation such as milking, midwifery, mating, and injection treatment, operators should disinfect first, and at the same time sterilize cow's breasts, nipples, vaginal openings, etc. to prevent infection of mastitis and endometrium. Inflammation and other diseases ensure the health of the cattle body. Can not use the same quality disinfectant for a long time, so as to avoid drug resistance.

Understanding drinking water disinfection is a mistake Drinking water disinfection is the disinfection of drinking water. Drinking water from livestock and poultry is disinfected water, not drinking disinfectant. Drinking water disinfection kills microorganisms in drinking water. Many disinfecting drugs, the instructions said "efficient, broad-spectrum, harmless to humans and animals," can 100% kill a virus, a virus, used for drinking water or spices and oral, in 1 to 3 days to kill a virus propaganda, Misled sterilizers. The commonly used water disinfectants in the clinic are chlorine preparations, quaternary ammonium salts and iodine preparations.

When drinking water is disinfected, if the dose of the drug is not well controlled or the amount of drinking water is not accurately estimated, the concentration of the disinfectant in the water may be increased. If drinking for a long time, it may kill or inhibit the cow's intestine in addition to acute poisoning. The normal flora in the road causes the normal digestion of dairy cows to be disordered, which is harmful to the health of dairy cows.

Misconception that quicklime can sterilize the lime that is purchased from the market is calcium oxide, which itself has no disinfection effect, and only when adding water equivalent to 80% to 100% of the weight of quick lime, mature lime is produced and the hydroxide ions are dissociated and sterilized. effect. Lime is a disinfectant with good disinfection, no pollution, no special odor, cheap and easy to use, and easy to use. Some cattle farms place thick dry limestone in the disinfecting tanks, allowing people to step on and roll the car so that they will not be able to disinfect; some directly spread dry lime on the roads and playgrounds, causing lime dust to fly up and be cows. Inhalation of respiratory tract, artificially induced inflammation of the respiratory tract; some use liming for too long time for disinfection, but also do not achieve disinfection effect, because slaked lime has absorbed carbon dioxide in the air, into calcium carbonate, no hydroxide ion Completely lost the role of sterilization. The best method of disinfecting lime is to formulate 10% to 20% lime milk, which can be used for brushing the wall of a cow house to be sterilized and disinfected. It can also be used to beautify the environment. Always add water and add quick lime in the disinfection tank.

Before the disinfection, the dairy farm is not mechanically cleared. Before the disinfection, the removal of organic matter such as cowsheds, cow dung from the stadium, and feed residue is often neglected. To fully play the role of disinfecting drugs, it is necessary to make the drug directly contact with pathogenic microorganisms. These organisms contain a large amount of bacteria. At the same time, disinfecting drugs and organic proteins have different degrees of affinity and can be combined into water-insoluble compounds. Disinfecting drugs are consumed by a large amount of organic substances, which hinders the exertion of drugs and greatly reduces the number of drugs. The killing of pathogenic microorganisms requires the consumption of large doses of disinfecting drugs. Therefore, the thorough mechanical removal of organic material from cattle farms is a prerequisite for efficient disinfection.

When cows are milking, it is not possible to achieve uniform milking in a cow-scale disinfection cow-farming community, which often leads to the spread of cow diseases. Due to the relatively tight milking time, in the milking process, the milking cups of the milking machine cannot be well disinfected, and only the milk of the cows is often simply rinsed. This will lead to the spread of infectious diseases such as mastitis. The best way is to brush the cow body, wash the breasts, disinfect the breasts, and wash the nipples before milking the cows; disinfect the teat cups with a cow to prevent cross infection. .

[Composition]

The main component of this preparation is human immunoglobulin, which is prepared by cold ethanol fractionation of human plasma from healthy donors. The manufacturing process contains a step to remove anticomplementary activity and a dual viral inactivation process. It contains a suitable amount of glucose or maltose as stabilizer (see table below), but does not contain any antiseptic or antibiotic. The distribution of IgG subclasses is close to the serum level of normal subjects and maintains the bioactivity of Fc fragment of IgG.

[Indications]

1. Primary agammaglobulinemia, such as X-linked hypogammaglobulinemia, common variant immunodeficiency diseases, immunoglobulin G subclass deficiency, etc.

2. Secondary immunoglobulin deficiency diseases, such as severe infection, septicemia of newborn, etc

3. Autoimmune diseases, such as primary thrombocytopenic purpura, Kawasaki disease
