Cow health care is the use of preventive medicine. The implementation of comprehensive measures for prevention and health care of dairy cows is a systematic project to ensure stable production, high yields, health, and longevity of dairy cows.
Strictly implement the health and disease prevention system
1. The main prevention is to strictly disinfect cattle farms to build walls or epidemic prevention ditch. Disinfection tanks (to maintain 2% to 4% sodium hydroxide solution and other disinfectants for years) and disinfection rooms should be set up at the entrance. Workers' uniforms and rubber shoes must be kept clean and cannot be worn off the court; vehicles and pedestrians are not allowed to enter the venue; production areas are not allowed to dissect bodies, dogs, pigs and other livestock and poultry are not allowed, and mosquitoes and flies are regularly eliminated. At least two disinfections per year are conducted in spring and autumn each year; veterinary equipment and insemination equipment should be thoroughly disinfected according to regulations; corpses and placenta should be buried deeply; excrement should be piled up and disinfected by biological heat.
2. Regular quarantine, vaccination and tuberculosis quarantine inspections are conducted twice a year, in April and October of each year; Blood test tube agglutination tests for brucellosis are conducted one or two times a year. If a miscarriage occurs, bacteriological culture of the stomach fluid and liver and spleen tissues of the aborted fetus should be done to find out the pathogen. Anthrax spores are inoculated once a year, from December to February of the following year. In order to prevent brucellosis in some cattle farms, 5 to 6 months old calves are subjected to oral or subcutaneous injection of Brucella bacillus 19 (or porcine type 2 bacilli and sheep type 5 bacterins). Injection should adhere to the "three strict, two standards, one does not leak." Namely: strict implementation of the vaccination system, strict disinfection, strict registration; vaccination volume should be accurate, injection site should be accurate; do not miss a cow.
3. Periodically repel insects, strengthen management and protection, conduct inspections of body parasites such as cockroaches every spring and autumn each year, and from June to September, the epidemic areas of coccidiosis should be regularly inspected and exterminated. In October The cattle were subjected to one-time prevention and deworming work such as liver flukes, and the yak herds were subjected to general census and deworming work in the spring. Strictly controlling the access of cattle and cattle that have already been sold, will no longer return to the market. Every outside cow must be quarantined for tuberculosis and brucellosis and isolated. Those who are negative are admitted. Pigs, sheep, chickens, etc., are prohibited from entering cattle farms.
Measures to be taken after the outbreak
1. Strict monitoring and detection of diseased cows Because of individual differences, the incidence is sooner or later, symptoms are light and heavy, and some of the external manifestations are not obvious. In order to detect cows as soon as possible, to measure the temperature of each cow, and carefully observe the appetite, milk production, spirit, feces, and other comprehensive judgments, all suspicious individuals should be isolated from the herd in time.
2. Timely isolation, centralized treatment in production, according to the actual situation of each farm, select the appropriate location, establish a temporary diseased cattle isolation station. In the isolation station, the diseased cattle are treated and their changes are observed at any time; at the same time, care must be taken to promote the recovery of diseased cows as soon as possible.
3. Strictly blockade and disinfection 1. Control the flow of cattle, and it is forbidden for outside vehicles and personnel to enter. 2 Thoroughly sterilize contaminated equipment, forage, mat grass, feces, and pens, etc., and the dead bodies are buried deeply and chemically. 3 Every 7 to 15 days, the whole field is disinfected with 2% lye, and summer should be done to eliminate mosquitoes and flies. 4 If necessary, the cattle can be vaccinated. 5 After the last diseased cow was cured, slaughtered or died, after a certain period of closure, no epidemic disease occurred. After a comprehensive terminal disinfection, it was approved by the relevant unit before the blockade was lifted.
