Pig farm disinfection and hygiene management

Pig disease is mainly caused by the spread of pathogenic microorganisms, and the ideal habitat for pathogenic microorganisms is the pig house. That is to say, pathogenic microorganisms live in all corners of pig production, such as open space, houses, air, etc. The reproduction, growth and spread of pathogenic microorganisms are the key to protecting the health of pigs. Controlling the growth, reproduction and spread of pathogenic microorganisms does not provide them with a place to survive and spread. In other words, pig farms provide a good environment for pigs. Effective disinfection measures can reduce the number of pathogenic microorganisms in pigs' growing environment and provide a good living environment for the pigs.
Health of pigs 1. Clean the sheds in a timely manner and clean up the production of garbage. Keep the interior and exterior clean and tidy. The used items are arranged in an orderly manner.

2. Keep the house clean and dry. Every day, you must clean the pig's excrement in the circle to make sure that the pig and manure are separated. If the pig house is dry and excrement, clear the pig manure to the designated place every morning and afternoon; if it is In the pighouse where the water flushes the excrement, the pig manure is cleaned to the ditch with clean water in the morning and afternoon every day to keep the pig body and the pen house clean.

3. Transfer a batch of pigs once a week. After idling, clean and disinfect. Breeding pigs go to bed or adjust the circle. Wash the empty circle first and then disinfect it with a broad-spectrum disinfectant. In the delivery room, wean a batch, bred each fattening batch, fatten Every batch of slaughter, first clean, and then use fire alkali atomization after 1 hour rinse, disinfection, fumigation, disinfection.

4. Pay attention to ventilation, air conditioning in winter, good indoor air, and fan ventilation in winter 5-10 minutes (each section according to the specific conditions of ventilation). Summer ventilation cools down and discharges harmful gases.

5. Production waste, ie used medicine boxes, bottles, vaccine bottles, sterilizing bottles, and disposable infusion bottles shall be immediately burned or properly placed in one place, and shall be destroyed and processed in a timely manner. Bags can be returned to feed mills and cannot be used for incineration.

6. The overall environmental sanitation within the homes includes roofs, doors and windows, corridors and other places that are not easily cleaned. After each empty home is thoroughly cleaned, it must not be cleaned once every month or quarter. Home environment hygiene is cleaned every month.

7. Four-year rodent control, mosquitoes and flies in summer. The rat drug is dispensed once a quarter and is administered to humans and pigs as harmless rat drugs. At the onset of summer, mosquitoes and flies were given to feedstuffs or sprayed flies.

The disinfection of pigs is divided into regular disinfection and emptying. Regular disinfection refers to the disinfection of pigs, field disinfection and certain prescribed disinfection. Empty room disinfection means that the pigs in the building are all disinfected after being transferred out or slaughtered.

The procedures followed in the sterilisation: cleaning, disinfection, flushing, fumigation

1 After emptying, thoroughly remove any residual materials, garbage, door and window dust, etc., and arrange the utensils. After the delivery room is empty, the pig troughs are brought together, and the cushions of the incubators stand upright on the incubators for easy cleaning. After the bred, fattened and reared pigs are empty, the debris, rubbish, door and window dust, etc. inside the house are completely removed. And arrange the utensils.

(2) Clean the equipment and utensils in the house and apply low-pressure spraying to the surface of all objects with a concentration of 2% to 3% caustic soda to make it fully wet. The spraying range includes the ground, pigsty, and various utensils, etc. After infiltration for 1 hour Rinse the ground, food trough, pigsty, and other utensils thoroughly with a high-pressure cleaner until it is clean and clean. While rinsing, pay attention to the lamp socket of the delivery room and the switches and sockets of each power supply.

3 Thoroughly sterilize all empty surfaces, equipment, and utensils with a broad spectrum disinfectant and leave no dead ends. After disinfection, fumigate with potassium permanganate and formaldehyde for 24 hours, ventilate and dry for 5-7 days.

4 Restore the layout of the house within 2 days before entering the pig, and check the maintenance equipment, and then use a broad-spectrum drug to disinfect once.

Regular disinfection

1 The disinfection tank that enters the production area must maintain the effective concentration of the solution. The concentration of the fire alkali in the disinfection tank should reach 3%, and be changed every three days.

2 The employee who enters the production area or enters the production area must go through the “stepping, lighting, washing, and changing” four-step disinfection procedure to enter the field area, ie, stepping on a fire basin or pad, irradiating ultraviolet rays for 5-10 minutes, and bathing in the shower room. Replace uniforms and shoes.

3 Items entering the site can enter the production area after being exposed to ultraviolet light for 30 minutes. Items that are not afraid of wetness can enter the site after soaking or disinfection, or they can be fumigated once.

4 The out-purchased pig vehicles shall be strictly spray-disinfected 2 times before loading the pigs. After the pigs are installed, the used pig racks, scales and aisles shall be promptly cleaned, washed and disinfected.

5 There is a disinfection pool at the door of each unit. When the personnel enters or exits, the feet must step into the disinfection pool. The disinfection pool must maintain the effective concentration of the solution.

6 Each house shall be cleaned and sterilized with a pig spray according to the provisions. The external environment shall be disinfected according to the circumstances, 2 times a week or 3 times a week or once a week. Off-site production areas, loading pigs, and crematoriums must be sterilized without leaving corners. Disinfectants are used alternately.

Selection of disinfectants and disinfectants commonly used in pig farms

Classification of disinfectants

1 Iodine preparations, such as iodine, chlorothalonil, and fast-acting iodine. If type I fast-acting iodine, it can be used for 300-400-fold dilution if it is used for piggery disinfection, 350-500 times if it is used for feeding tank disinfection. Diluent, kill foot and mouth disease virus can be prepared 100-150 times dilution, the specific usage, see the instructions.

2 strong alkaline fire alkali (content of not less than 98%) solution is mainly used for empty homes, field areas, the external environment of the disinfection. Lime powder or stone powder milk can also be used for disinfection. The lime powder is both sterilized and moisture-proof. It is suitable for the production room, piglet breeding house, or scattered around the field area to form a separation zone.

3 Quaternary ammonium salts such as 1210, Anli 2000, and 100 toxins are used at a concentration of 1:1000-2000. Such disinfectants are mainly suitable for the establishment of new farms. Because of the number and types of pathogenic microorganisms.

4Aldehyde Formaldehyde, also known as formalin, can be used for surgical disinfection, environmental disinfection, or as a preservative depending on the concentration. As a method of gas disinfection for piggery and silos, a volume of 1 cubic meter is filled with 20 ml of formalin, heated with an equal amount of water to evaporate it into gas; as a fumigant, 14 ml/m3 of formalin plus 7 g /m3 potassium permanganate, fumigation 8-10 hours or 24 hours.

5 peroxides such as peracetic acid is divided into A, B two bottles, when used in the first A, B liquid mixing 24-48 hours after use, the effective concentration of about 18%, spray disinfection concentration of 0.2% - 0.5%, now with the current allocation.

6 chlorine preparations such as bleaching powder, disinfection Wei, 99 disinfection king, etc., disinfection Wei used the concentration of 400-500 times solution spray disinfection.

7 phenols such as bacteria poisoning, the use of a concentration of 1:100-1:300

8 Weak acids such as anti-virus net, using a concentration of 1:500-1:800

Disinfectant selection

1 The selected disinfectant has the characteristics of strong efficacy, wide effect, quick and long-term effect, good stability, strong permeability, good toxicity, low irritation and corrosion, and moderate price.

2 Fully consider the type of disease, prevalence and disinfection targets, disinfection equipment, and farm conditions in the field, and select several different disinfectants that are effective for different diseases.

3 Fully consider the types, epidemics, and disinfection targets and possible development trends of the epidemic in the region, and select several disinfectants of different natures that are effective for disinfection of different diseases.

Things to note when using disinfectants 1 Dilution concentration Dilution concentration is the minimum concentration necessary to kill the most resistant pathogenic microorganisms.

2 Liquid dosage Any effective disinfection must thoroughly wet the surface being sterilized. The minimum amount of liquid to be sterilized is 0.3L/m2, usually 0.3-0.51/m2.

3 The duration of the disinfectant should be as long as possible. Keeping the disinfectant in contact with the pathogenic microorganisms generally has a better effect for more than half an hour.

4 Before sanitizing, clean and sanitize as much as possible to eliminate the unfavorable factors (feces, urine, garbage) that affect the disinfection effect.

5 is now used, mixed evenly, to avoid the phenomenon of disinfection while adding water.

6 Disinfectants of different nature cannot be mixed.

7 Regularly use disinfectants.
