摘　　要：通过对剑白香猪(Ⅰ系、Ⅱ系)在7、8月热应激条件下的繁殖性状和生物学特性测,结果表明,热应激条件下,总产仔数、产活仔数偏低,Ⅰ系、Ⅱ系平均产活仔猪分别为46.4%和8.0%;Ⅰ系中,公猪走动的占90.0%,母猪走动的占30.0%,生长发育猪走动的占92.1%;Ⅱ系中,公猪走动的占80.0%,母猪走动的占36.4%,生长发育猪走动的占79.1%;猪的心跳加快;呼吸频率增加;饮水量增加;喜食青料;腹泻、皮肤患病率增加,Ⅰ系、Ⅱ系腹泻的发病率分别是61%、29%,皮肤病的发病率分别是19%、67%。Reproductive characters and biological traits of Jianbai Xiang pig including Line Ⅰ and Line Ⅱ were observed under the condition of heat stress in July and August. The results showed that under the condition of heat stress,the litter size and the live litter were lower,the average live litter of Line Ⅰ and Line Ⅱ was 46.4% ,8.0% ;in Line Ⅰ the stock boar of going around accounted for 90. 0% ,sow for 30. 0% ,and growing pig for 92. 1% ;in Line Ⅱ the stock boar of going around accounted for 80. 096 ,sow for 36.4% and growing pig for 79.1% ;heartthrob sped,respiratory rate accelerated,water consumption raised;liked green forage;diarrhea and skin disease incidence increased, the rate of diarrhea of Line Ⅰ and Line Ⅱ were 61% ,29% ,the rate of skin disease of Line Ⅰ and Line Ⅱ were 19% ,67%.
