A group of ducks in the breeding process, due to feeding and individual differences and other factors, often 10-20% of the ducks produce little or no eggs. In order to reduce the cost of raising and increase the egg production rate of ducks, it is possible to phase out low-yield ducks during the production period based on the following characteristics.
1. The breeding period is more than 3 years.
2. Feathering early, long time, and many times.
3. Cloaca is small, wrinkled and dry.
4. The neck of the head is thick and short, the mouth is short and narrow, and the tip is flat, and the upward protrusion is not obvious.
5. The abdomen is small and hard, the pubic bone can only accommodate 2 fingers at the end, and the high-yield duck can accommodate 3-5 fingers.
6. The thoracodorsal stenosis, rough feathers, fluffy and dull.
7. The body is short, the base of the wing and the heel of the leg are only 3-4 fingers apart, and the high-yield duck is generally more than 4 fingers apart.
8. The body is overweight, gluttonous and lazy duck.
9. When carrying a duck neck, keep your feet up and down. The high-yield duck's legs are straight and do not swing.
10. Diseased and disabled ducks, such as lameness, misshapen eggs, habitual production of soft-shelled eggs, and poorly skinned ducks.
