鸣管鉴别法
Sounding tube identification method
鸣管又称下喉,位于气管分叉的顶部。公鸭在此处有一个膨大的球状鼓室,直径为3~4毫米,从体外胸前可以摸出,母鸭无此鸣管。
The sounding tube, also known as the lower larynx, is located at the top of the bifurcation of the trachea. Here the male duck has an enlarged spherical tympanum with a diameter of 3 ~ 4 mm. It can be felt from the outside chest. The female duck does not have this sounding tube.

左手托住初生雏鸭,使其背朝天,腹朝下,以大拇指和食指轻夹颈部,用右手大拇指和食指轻轻平提肛门下方,先向前按,随着向后退,如感触到有其麻粒或油菜籽大小的突出之物,是公雏鸭,否则则为母雏鸭。
Hold the newborn duckling with his left hand with his back to the sky and his abdomen to the bottom, gently clip the neck with his thumb and index finger, gently lift the lower part of the anus with his right thumb and index finger, press it forward first, and then move backward.

将初生雏鸭握在左手中,用中指和无名指夹住鸭的颈部,头向外,腹朝上,成仰卧势。然后用右手大拇指和食指分开肛门旁边的羽毛挤出胎粪,轻轻地将肛门张开,并使其外翻。公雏鸭可见到长约4毫米的突起物(阴茎),母鸭则无,或仅有残留痕迹。
Hold the newborn duckling in the left hand, clamp the neck of the duck with the middle finger and ring finger, head outward, abdomen upward, and form a supine position. Then use the thumb and index finger of your right hand to separate the feathers next to the anus and squeeze out the meconium. Gently open the anus and turn it out. Male and ducklings can see protuberances (penises) about 4mm long, while female ducks have no or only residual traces.
