There will be diseases in the cattle breeding process. It is very difficult for us to eliminate germs. Only pay attention to the management of various details to minimize the occurrence of diseases. The prevention and control of cow diseases are also the same.
The following are the prevention and treatment methods for dairy diseases:
1. Strengthen environmental control
The production area of the dairy farm should be isolated from the living area. Animals such as cats, dogs, pigs, chickens, ducks, etc. should not be kept in the field, and other animals should be prohibited from entering and exiting. Make effort to eliminate the vectors such as rats and flies; the entrances and exits of dairy farms and barns should be set up. Disinfecting tank, a built-in effective disinfectant such as 3%~5% to Sol solution or 20% lime milk, every 10 days; all utensils in the barn are disinfected once every half month, and the delivery room (room) is before the production of the cattle. And after the delivery, each time large disinfection, the cattle farm is carried out 2 times to 4 times a year.
2. After detecting the epidemic
The sick dairy cattle, the positive cattle, the cattle beds of the suspected cattle and their troughs are disinfected once a day, and the feeding tools are disinfected in time after use. The excrement such as feces should be collected separately for harmless treatment, and the sports ground should be thoroughly cleaned and continuous disinfection for 3 days to 5 days.
The metal facilities and equipment of the dairy farm are disinfected by means of flames, fumigation, etc.; feeding troughs, feeding tools, cowsheds, ceilings, floors, walls, urinals, delivery rooms, etc., 2% caustic soda, 5% to Sur, Or disinfection of chlorine preparations; disinfection of the sports ground with 20% lime milk; feed and litter of the farm shall be deeply buried or fermented; the manure shall be stacked and sealed for fermentation or deep burial.
3. Isolation of the disease cattle
All large-scale farms (households) should have isolated barns, which are located at the lower vents and are separated from the healthy barn by more than 50 meters. The "two-diseases" diseased dairy cows or the positive cattle found must be kept in the isolation barn before culling harmless treatment. For the suspected "two-diseases" diseased cattle must be re-examined in the isolated barn.
The dairy farms (households) that have not established the isolation of the barn, the "two diseases" diseased cattle, the test positive cattle, the suspected cattle must be isolated on the spot, concentrated in the district, timely culling harmless treatment or re-examination, and measures such as strengthening disinfection and fixing tools should be taken to prevent the spread of infectious diseases.
Harmless treatment of sick cattle for the discovery of "two diseases" diseased cattle or test positive cattle, it is necessary to promptly cull harmless treatment. "Two diseases" diseased cattle, detection of positive cattle to kill the milk produced before the harmless treatment, "two diseases" suspicious cattle produced during the isolation of the cow's milk, all need to be treated by high temperature and other harmless treatment. The fetus, the placenta, and the feces of the brucellosis-infected cattle and the positive-positive cattle are all buried harmlessly to prevent the infection of humans and animals.
4. Purification of contaminated cattle
The cattle group (field) that is diagnosed as "two diseases" or the "two diseases"-positive cattle is the "two diseases" pollution group (field) of cattle, and the "two diseases" purification work should be fully implemented.
① Treatment of contaminated cattle (field): repeated monitoring of cattle, brucellosis-contaminated cattle (field) were detected once every two months, tuberculosis-contaminated cattle (field) were detected once every 3 months and found the sick cattle and positive cattle are culled in time, and the suspected cattle are quarantined and re-examined in time.
② Assume the treatment of healthy herds: the herd after culling the diseased cattle and positive cattle is a hypothetical healthy herd. It is assumed that the treatment of healthy herds is the same as that of contaminated cattle; if the results of more than two consecutive monitoring results are negative, it can be considered as a healthy herd.
③The cultivation of healthy yak herd: set up a yak breeding house. The yak breeding house should be far away from the female cows more than 500 meters. It is assumed that the female yak born by healthy cows is managed by a special person and fixed feeding tools are used. After the yak is born, it is disinfected with 3%~5% of the Sol solution, dried and placed in the yak breeding house. The yak was transferred to the production group after being bred for 6 months in the yak breeding house. During this period, the "two diseases" were continuously tested three times at 20 days, 100 days to 120 days and 6 months, and the yak entered the breeding room. Before, after each "two diseases" test and after the transfer group, the yak breeding room was disinfected once. For dairy farms (households) where there is no yak breeding house, the female yak born by the cows should be kept away from the separate areas of the cows and cleaned accordingly.
Summary: These are the prevention and treatment methods of cow diseases. We must strengthen the control of the environment. When the disease is detected, we must do the isolation and disinfection work promptly. We must strictly clean the contaminated areas.
