Milk quality and safety production question and answer

How to rationalize the dairy farm?
Dairy farms (communities) generally include 3 to 5 functional areas, namely living areas, management areas, production areas, manure treatment areas and diseased animal management areas. The specific layout should follow the following principles.
(1) Living area. It should be built in the cattle farm (cell) uptake and high-lying areas, and maintain a distance of more than 100 meters with the production area.
(2) Management area. Including buildings related to business management. The management area must be strictly separated from the production area and a distance of 50 meters or more must be ensured.
(3) Production area. It should be located in the downwind position of the site. The population department should set up a disinfection room, a dressing room and a vehicle disinfection pool. The cowhouse should be rationally laid out to meet the requirements of dairy cows in stages and in groups. The dairy cowshed should be built near the milking parlor. The cowshed should be kept at a proper distance and neatly arranged for easy prevention and fire prevention. The hay warehouse, feed storehouse, feed processing and modulation workshop, and silo storehouse should be located in the high-lying areas at the edge of the production area.
(4) Excreta wastewater treatment, diseased animal management area. It is located in the lower part of the production area and has a lower elevation and maintains a distance of more than 300 meters from the production area. There is a separate passage to isolate the diseased cattle, disinfect and treat the waste. The pit or crematorium is more than 300 meters away from the cowshed.
What principles should be followed for building a suitable dairy cowshed?
The purpose of building a cowshed is to create a suitable living environment for cows and guarantee the health of cows and the normal operation of production. For this reason, the design of the cowshed should grasp the following principles: 1 Create a suitable environment. Including temperature, humidity, ventilation, light, and control of carbon dioxide in the air, ammonia, hydrogen sulfide, to create a suitable environment for livestock. 2 Meet the requirements of the production process to ensure the smooth progress of production and the implementation of animal husbandry and veterinary technical measures. 3 Strict health and epidemic prevention to prevent the spread of the disease. By building a standardized cowshed, it will create a good environment for livestock and prevent and reduce the occurrence of epidemics. It is necessary to reasonably conduct site planning and building layout according to the requirements of epidemic prevention, determine the orientation and spacing of livestock houses, set up disinfection facilities, and properly arrange the sewage treatment facilities. 4 To be economically reasonable and technically feasible.
What are the points for health and epidemic prevention in dairy farms?
(1) General rules for epidemic prevention. Dairy farms should implement the principle of "prevention first, prevention and control combined". The purpose of daily epidemic prevention in dairy farms is to prevent the introduction or occurrence of diseases and control the spread of infectious diseases and parasitic diseases.
(2) Anti-epidemic measures. Dairy farms shall be subject to compulsory immunization in accordance with national regulations and shall be subject to regular inspections by the epidemic prevention department. Dairy farms should establish an entry and exit registration system. Non-production personnel are not allowed to enter the production area and they are not allowed to visit outsiders. When employees enter the production area, they must wear overalls and enter the market after being sterilized and hand sanitized. Every year, the dairy farm staff must conduct a health check to find out that infectious diseases should be promptly treated outside the clinic, and they can only take up posts after recovery. New recruits must undergo a health check to confirm that there is no tuberculosis and other infectious diseases. Dairy employees are not allowed to work together in workshops. The production tools of each workshop must not be used interchangeably. No other livestock and poultry shall be kept in the dairy farms, and other livestock and poultry products shall not be brought into the entry area.
Pile up cattle dung at regular intervals and regularly spray insecticides to prevent breeding of mosquitoes and flies. The dead cows should be treated harmlessly and clean and disinfect the articles that come in contact with the bodies. Only the quarantine and sale of cattle shall be subject to quarantine and quarantine certificates shall be issued before they can be released. The cattle transport vehicles must be strictly sterilized before entering the designated area. When a suspected infectious disease occurs in a dairy cow or a severe infectious disease occurs in a nearby pasture, isolation and blockade and other emergency measures should be taken immediately.
What are the main points of disinfection of dairy farms?
(1) Disinfectants. Disinfectants should be selected to be safe to humans, dairy cows and the environment, have no residual toxicity, have no damage to the equipment and do not harm the body surface of cattle and do not produce disinfectants in the cattle body.
(2) Disinfection method. Spray disinfection, dip liquid disinfection, ultraviolet disinfection, spray disinfection, hot water disinfection.
(3) Disinfection system. A disinfection system was established to sterilize the environment, cowsheds, utensils, outsourced cows, personnel, and pre-production (milking, midwifery, mating, injection treatment, and any contact with cows) of the farm (cell).
