The management of early spring is very important for pig production. The weather in early spring and March, most of the regions are cold, warm, and warm, and the fluctuation of temperature is very frequent. Cold waves and strong cold air are often affected.
The environment should be dry pigs like the dry environment, especially the body temperature regulation function of piglets has not yet been developed, the body surface deposition of less fat, cold resistance is poor. Suddenly, the weather in Changqinghuyin is fickle and the temperature difference between day and night is relatively large. Therefore, keeping warm can provide a good growth environment for pigs. Keeping the pigsty warm, dry and ventilated is the top priority for spring pig raising. Hang curtains, plug loopholes, and lock the shed to ensure the pig house is warm, clean and airy. In northern regions, sows are also required to implement a warm real estate to ensure that the piglets are fully active and full.
Sterilization should be thorough in the spring to thoroughly disinfect the pigsty to prevent the growth and reproduction of germs. The sheds are cleaned and sprayed and brushed with 20% to 30% lime milk or 20% turfgrass or 2% to 3% pyrogenic alkali solution on the ground, walls, and surrounding environment of the enclosure. After cleaning the utensils, use 3% to 5% of soda water to disinfect and rinse with water to avoid causing poisoning or affecting the feed intake of pigs.
Disease prevention and deworming should be strengthened to strengthen the epidemic prevention and timely deworming. In spring, the occurrence of infectious diseases such as swine fever, erysipelas, lung disease, piglet paratyphoid, gasping disease, transmissible gastroenteritis, and piglet E. coli should be strictly prevented. Farmers should strictly follow the immunization procedures and do a good job of immunizing pigs. Avoid leakage and vaccine failure. If there is an outbreak in the surrounding area, besides the disinfection of piggery, it is also strictly prohibited that foreigners and vehicles enter the farm, and their vehicles and personnel should be thoroughly disinfected from the infected area.
