(1) Keep the pig house clean
Summer is the peak season for mosquitoes and flies, which not only causes poor production environment in pig farms, but also makes it difficult to prevent diseases in pig farms. Therefore, it is necessary to regularly disinfect the environment inside and outside the pigsty, including the barns, fields and appliances, instruments, drainage channels, air and the whole body surface of sows, and also pay attention to the disinfection of some dead spots.
At the same time, it is necessary to pay attention to the disinfection work of the empty column, and adhere to the principle of "all in, all out". Use disinfectants with a wide range of adaptability to the environment, such as chlorine preparation; in summer, the sun is sufficient, which can cause some disinfectants to decompose quickly and lose efficacy. For example, povidone iodine and complex iodine are not suitable for outdoor use.
(2) Feed scientifically and mix feed reasonably to ensure fresh feed
In summer, green feed rich in vitamins and minerals and cool feed such as watermelon peel should be fed; seasoning agents such as salty taste, fresh taste or fragrance should be properly added to the mixture to improve the palatability of feed, increase the feed intake of pigs, and forbid feeding moldy feed
Pigs can be fed four times a day in summer. In order to reduce the activity of pigs in the hottest period, they can be fed once at 4:00, 10:00, 16:00 and 21:00. Keep plenty of cool water in the trough. The pigs should be given 0.5% saline once a day to regulate their body temperature.
(3) Plant greening to improve microclimate
Reduce the proportion of cement floor in pig farm to reduce ground temperature. Increasing the green area of pig farm can reduce the temperature of pig house by 3-4 ℃ and reduce the heat radiation by 80%. However, the tall trees should not be various, which will affect the ventilation and attract wild birds, which is not conducive to epidemic prevention.
(4) In midsummer, do not use the method of pouring cold water on pigs to cool the pigs
If the weather is hot, you can dig a hole in the corner of the pigsty, and put enough cold water in the pit for the pig to bathe.
(5) Actively do a good job in epidemic prevention and control
In addition to immune injection according to the immune program, prevention and control work should also be done for the frequently occurring diseases in high temperature season, such as sow's uterus inflammation mastitis no milk syndrome, piglet yellow and white dysentery, coccidiosis, toxoplasmosis, eperythrozoonosis and chlamydia.
