The identification of male and female ducklings plays an important role in the production of ducks, especially the production of parent ducks and commercial ducks. Egg-type ducks should be selected when they are first born to be treated separately, which can save the cost of brooding premises, equipment, feed, and transport; meat-type can be fed in groups of males and females, developed neatly, and the ducks can be pressed. Nutrition requires feeding, promotes fast fattening, and shortens the feeding period; ducks can be provided at the sex ratio when sold. Therefore, the modern duck industry attaches great importance to identifying males and females. Experience identification method: When identifying, the left hand grasps the duck, the duck head is down, the abdomen is upwards, backs the palm, the appraiser's right thumb and forefinger pinch both sides of the anus, gently rubs, if feels like there is a sesame in the anus The small protrusions can slide on the upper end and are relatively fixed at the lower end. This is the penis, which can be judged as a male duck. If there is no such small protrusion, it is the female duck (when the mother and young chick rubs with their fingers, they have cloacal muscle folds. With moving, but no sesame point feeling). When using the pinch anal differentiation method, the surgeon must have a thin hand and feel sensitive to learn, and the accuracy rate can reach over 99%. The anal veritometry method: turn the anus law with his left hand to hold the ducklings, the ducklings neck sandwiched between the middle finger and the ring finger, the two feet sandwiched between the ring finger and the little finger, gently hold the hand firmly, and then press with his left thumb Live in the umbilicus, excrete meconium with a little force, then use the right thumb and forefinger to open the anus, turn it out, and see half-grain long spiral penis exposed, then it shows that it is a male duckling, otherwise, it is a mother duck. The top of the anal identification method: the left hand holding ducklings, with the right index finger and ring finger clip the young duck on both sides of the body, the middle finger gently outside the anus in a top, if you feel a small protrusion, that is, male ducks. The anal fistula is harder to grasp than the pinching anal method, but the speed of the anal approach is faster than the anal approach. The method of identification of sounding Tube: In the two clavicles at the base of the duck neck, there is spherical cartilage at the trachea bifurcation, which is called the sounding tube and is the vocal organ of the duck. The ducklings of the ducklings are larger, with a diameter of 3-4 mm and a horizontal cylindrical shape, slightly to the left. The ducklings of the mother ducklings are small and only in the bifurcation of the trachea. When touching, raise the duck's head with your left thumb and forefinger, hold the duckling with your right hand from the abdomen, and touch the base of your neck with your index finger. If there are small protrusions with a diameter of 3-4 mm, you should be a duckling.
