2.1.1搭da設she遮zhe蔭yin棚peng
，防fang止zhi陽yang光guang直zhi射she。可ke在zai公gong豬zhu圈quan舍she上shang方fang搭da建jian棚peng架jia，並bing在zai圈quan舍she周zhou圍wei種zhong植zhi一yi些xie攀pan爬pa植zhi物wu，或huo在zai棚peng架jia上shang鋪pu上shang樹shu枝zhi，可ke起qi到dao防fang止zhi陽yang光guang直zhi射she而er降jiang低di豬zhu舍she環huan境jing溫wen度du的de目mu的de。特te別bie是shi敞chang開kai式shi豬zhu舍she
，更geng應ying采cai取qu遮zhe陽yang措cuo施shi來lai防fang止zhi陽yang光guang直zhi射she，降jiang低di豬zhu舍she地di麵mian溫wen度du和he環huan境jing溫wen度du。

2.1.2采取淋（滴）水shui降jiang溫wen。在zai豬zhu舍she內nei架jia設she噴pen淋lin設she施shi

，在zai環huan境jing溫wen度du較jiao高gao時shi，尤you其qi是shi中zhong午wu，通tong過guo水shui控kong製zhi閥fa，每mei隔ge一yi段duan時shi間jian對dui圈quan舍she進jin行xing噴pen霧wu，以yi達da到dao降jiang低di豬zhu舍she環huan境jing溫wen度du和he地di麵mian溫wen度du的de目mu的de。敞chang開kai式shi豬zhu舍she除chu了le應ying采cai取qu遮zhe陽yang措cuo施shi外wai

，采cai用yong滴di水shui降jiang溫wen措cuo施shi比bi較jiao適shi用yong
，也ye比bi較jiao簡jian單dan。具ju體ti方fang法fa是shi
，在zai豬zhu舍she內nei一yi定ding高gao度du架jia設she一yi條tiao塑su料liao管guan，在zai進jin水shui端duan裝zhuang上shang閥fa門men，在zai水shui管guan上shang鑽zuan上shang小xiao孔kong或huo裝zhuang上shang水shui龍long頭tou
，通tong水shui後hou
，水shui自zi小xiao孔kong流liu出chu或huo自zi水shui龍long頭tou流liu出chu。滴di水shui時shi間jian和he滴di水shui速su度du可ke通tong過guo閥fa門men來lai控kong製zhi。

2.1.3加jia強qiang通tong風feng，供gong給gei充chong足zu的de飲yin水shui。高gao溫wen天tian氣qi
，由you於yu氣qi溫wen較jiao高gao，公gong豬zhu對dui水shui的de需xu要yao量liang較jiao大da
，公gong豬zhu的de生sheng活huo環huan境jing，特te別bie是shi圈quan舍she和he氣qi味wei變bian化hua較jiao快kuai。因yin此ci，公gong豬zhu圈quan舍she內nei安an裝zhuang上shang自zi動dong飲yin水shui器qi或huo經jing常chang更geng換huan水shui槽cao中zhong的de飲yin水shui，保bao證zheng公gong豬zhu隨sui時shi飲yin用yong到dao清qing潔jie的de涼liang水shui是shi十shi分fen必bi要yao的de。在zai公gong豬zhu圈quan舍she特te別bie是shi封feng閉bi式shi豬zhu舍she內nei
，裝zhuang上shang電dian扇shan和he換huan氣qi扇shan，經jing常chang進jin行xing通tong風feng換huan氣qi

，可ke以yi有you效xiao地di改gai善shan公gong豬zhu生sheng活huo環huan境jing。

2.1.4適當調整公豬的一些活動規程。首先是調整公豬的運動時間。一般在比較涼爽的時間段，如清晨7dianyiqian
