养蚕的过程中怎样检查蚕的体质？饲养员每天与蚕儿接触，在饲养过程中，对蚕的体质可通过看、吹、听、触的方法来进行判断。在此，帮农网小编就给大家讲一讲养蚕的过程中检查蚕儿体质的方法。
一、看：收蚁时，看看是否有大小不齐蚕或死蚕。头大尾小、口吐清水，蚕粪粘连、吐丝多、向四方乱爬等现象发生，即为中毒蚕或病蚕。1~3龄蚕的粪粒坚硬呈墨绿色，在蚕座上滑动沙沙作响者为强健，若排粪柔软粘于尾部或粪粒呈红黄色者为体弱；若用手轻挤尾部，有黄水泌出者，为有病象征。蚕儿活动正常为强健，若经常匍匐不动或隐伏于蚕座中或向蚕匾四周乱抓者为体弱。蚕身青白、蚕体匀整、尾角翘起者为强健；蚕前胸空透、后半身返黄、尾部削尖、尾角下垂者为体弱。眠蚕头胸部昂起为强健；头胸平伏为体弱。
二、吹：给桑前，用口轻吹蚕体，若反应灵敏，个个头胸抬起作警惕状的为好；若反应迟钝或若无其事，则体质不强。
三、听：大蚕期食桑声大的为强健；盛食期不盛食，食桑无声或食桑声很小的为体弱蚕。
四、触：大蚕期用手背平触蚕身，感觉蚕体冰冷如水的为强健，有温热感的则体质欠佳。
在蚕体出现病症之前，通过“看、吹、听、触”发现体质不强的各批蚕儿，应及时调剂良桑，加强饲养管理。
