(1) Keep the pig house clean

夏季是蚊蝇du出没旺季，不仅造成猪场生产环境恶劣，更重要的是给猪场防病带来了困难。所以，要定期对猪舍内外环境，包括栏舍、场地和用具、器械，以及排水道、空气以及母猪全身体表等方面的，还应注意一些卫生死角的。

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.

同时，必须重视空栏工作，做到彻底空栏，坚持“全进全出”原则。使用对环境适应范围广的剂品种，如氯制剂等；夏季阳光充足，能使有些剂迅速分解而失效，如聚维酮碘、络合碘等不宜在室外使用。

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）科学饲喂，合理搭配饲料，保证饲料新鲜

(2) Feed scientifically and mix feed reasonably to ensure fresh feed

夏季应多喂富含维生素、矿物质的青绿饲料和果皮如西瓜皮等清凉饲料；在混合料中适当添加咸味、鲜味或香味等调味剂，以提高饲料适口性，增加猪的采食量，禁止饲喂发霉饲料

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

夏季喂猪可一日喂4次，为减少猪在更热时段的活动量，可于4：00、10：00、16：00、21：00各喂一次。要保持食槽内有充足的清凉饮水。每天还要给猪饮1次0.5%的淡盐水以调节体温。

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）植物绿化，改善场区小气候

(3) Plant greening to improve microclimate

猪场内减少水泥地面所占比例以降低地面温度。增加猪场地面绿化面积，可降低猪舍环境温度3～4℃，减轻热辐射80%。但高大树木不宜多种，影响通风，也能招来野鸟对防疫不利。

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）盛夏一定不要采用往猪身上泼冷水的方法给猪降温

(4) In midsummer, do not use the method of pouring cold water on pigs to cool the pigs

如果天气炎热，可以在猪圈一角挖坑，坑内放足凉水供猪洗浴。

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）积极做好疫病防治工作

(5) Actively do a good job in epidemic prevention and control

除按照免疫程序做好免疫注射外，针对高温季节多发病，如母猪子宫炎－乳房炎－无乳综合征、仔猪黄白痢、球虫病、弓形虫病、附红细胞体病、衣原体等病，也要做好防治工作。

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.
