Disease Prevention of Xiang Pig farming

In order to make Xiang pigs grow healthily and reduce the occurrence of diseases, we need to strengthen the management of Xiang pigs and do a good job in prevention.

First, strengthen hygiene management. 1. to do a good job in environmental hygiene, the environment of the pig house should be cleaned every day, keep it clean, and do a good job in killing flies, rodents and mosquitoes. Cultivate Xiang pig's fixed-point defecation habit, and concentrate Xiang pig manure in septic tank for biological fermentation disinfection, dredge and disinfect sewers and sewers, and eradicate mosquito and fly breeding places. 2. To do a good job of pig hygiene, it is necessary to remove the dirt on the body of fragrant pigs and remove the feces, urine, residues and sundries in the house in time. In the hot summer, clean water should be replenished in time so that the pig can cool down in the water; in winter, we should pay attention to changing the mat grass regularly, and at the same time, we should do a good job of ventilation to make the environment dry. 3. To improve feed hygiene in feed supply, it is necessary to prohibit the use of rotten, moldy and deteriorated feed. Feed should be fully cleaned and impurities removed before processing. Promote cooked food or feed pellet feed, to ensure the full price of feed nutrition. Cereal feed should be fully cooked to facilitate digestion and feeding utensils should be kept clean and disinfected regularly. Give enough clean drinking water to eliminate the remaining waste water every day.

Second, persisting in disinfection is an important measure to prevent and control infectious diseases. The methods of disinfection are generally physical, chemical and biological. Disinfection is the basis of disease prevention, so we should adhere to the principle of "combination of prevention and control, giving priority to prevention". When there is no infectious disease, it should be combined with the usual feeding and management to disinfect the fragrant pig houses, places and appliances that may be contaminated by pathogens. generally, disinfection can be carried out once a week with disinfectant solution or flame blowtorch. The sows should be thoroughly disinfected before giving birth and the young pigs should be transferred to another house. Disinfection pools should be set up in front of sick pig houses, litter houses and isolation houses, and attention should be paid to the frequent addition and replacement of disinfectants. When infectious diseases occur, the environment, articles and excreta of diseased Xiang pigs polluted by infectious diseases should be disinfected irregularly every day, and other uninfected Xiang pigs in the same group should also be urgently disinfected. Disinfectants usually use 10% bleach, 1% murine, 2% caustic soda, 2%-4% formalin or 5% murine 10% laisu water, and so on.

Isolation when infectious diseases occur in the farm, sick Xiang pigs should be isolated immediately, carriers of infectious diseases should be strictly prohibited from coming into contact with healthy Xiang pigs, and pay close attention to the situation of suspected infected Xiang pigs. Once symptoms occur, they should be quarantined immediately. All places and utensils such as pig sheds and utensils used by infectious Xiang pigs must be strictly disinfected. The personnel who raise healthy Xiang pigs and sick Xiang pigs should be separated. When they must come into contact, they should change their overalls and shoes, and carry out strict disinfection.

Fourth, regular deworming is an important measure to prevent parasitic diseases. In general, young Xiang pigs should be dewormed for the first time at the age of 6 months; young Xiang pigs under 6 months of age should be dewormed once a month; adult Xiang pigs should be dewormed once a quarter; breeding sows should be dewormed once before breeding; lactating sows and young Xiang pigs can be dewormed simultaneously. It is best to take a fecal examination before each deworming, and choose the appropriate deworming drug according to the results of the fecal examination. Commonly used broad-spectrum anthelmintic drugs, such as levamisole hydrochloride, can be taken orally according to 10 mg / kg body weight, used to dispel Ascaris lumbricoides, hookworm, filariasis, etc., or albendazole can be taken orally according to 25 mg / kg body weight.

Fifth, vaccination is an important measure to enhance the specific immunity of Xiang pigs and prevent the occurrence of infectious diseases. Vaccination usually uses vaccines, vaccines, toxoid and so on. At present, there are two types of vaccines for viral infectious diseases: decontamination vaccine and attenuated vaccine. Immune live vaccine, dead vaccine and toxoid used to prevent bacterial infectious diseases. Immunization usually uses subcutaneous injection, intramuscular injection and other methods.
