First, different body types.
When buying a duckling, it is usually a male duck with a big head, a round body and a pointed tail. On the other hand, ducks have small heads, flat bodies and scattered tails, mostly female ducks.
Second, nostril recognition method
1, the nostrils are narrow and small, and the male ducklings are linear along the muzzle. On the contrary, the mother duck's nostrils are bigger and slightly round.
2. The base of the mother duck's nose is soft, and there is no fluctuation on the plane; On the contrary, the nose base of male ducklings is thick and the plane lines fluctuate obviously.
3. Turn the duckling over so that its belly is facing the sky. Look at the edge of its fur. It is a half-moon or slightly flat and tidy female duckling. If it is obviously sharp and irregular, it is a male duckling.
Third, the sound tube is different.
The vocal tube, also known as the lower larynx, is located at the top of the tracheal bifurcation and is the vocal organ of ducks. There are great differences in morphological structure between male ducks and female ducks. The male duck has an enlarged spherical tympanum with a diameter of about 3 mm, which can be felt from the chest in vitro, while the female duck does not have such a sound tube.
Matters needing attention in raising ducks
1, temperature
The newly hatched ducklings have less fluff and poor thermoregulation function, so we should pay attention to keep warm. The general control method is to control the temperature at 33℃-35℃ for the first three days, and then reduce it by 65438 0℃ every day until it reaches the natural temperature.
2. Humidity
Although ducks like water, the humidity in the feeding environment is too high or too small to adapt. Generally, the humidity should be controlled at 70-75% in the first week, 65-70% in the second week, 60-65% in the third week, and 50-60% in the fourth week and beyond.
3. Feeding density
Too high and crowded feeding density of ducks will lead to high humidity and turbid air, which is not conducive to the growth and development of ducks. Generally controlled at: 20-25/m2 in the first week, 10- 15/m2 in the second week, 8- 10/m2 in the third week and 6-8/m2 thereafter.
4, health, disinfection and other daily work
It is necessary to do a good job in the sanitation of the duck house and playground, change the grass in the house, regularly use different disinfectants to disinfect the duck house, playground and its surroundings, and ventilate every day to keep the air in the duck house fresh. Provide ducks with full-price duck feed and green feed and plenty of drinking water every day.
