The four main reasons why ducklings are not raised

Recently, some peasant friends reported to the author that many of the ducks in their village had been raised for 3 months, but they only grew to about 1 kg and they weighed much less than expected. What are the reasons? The author analyzes the following main reasons:

1. Impure species. The current excellent duck species include Beijing Duck, Cherry Valley Duck and Di Gao Duck. They are all white feathers. They are produced by the crossbreeding of several species or strains. Their commercial growth is fast at the early stage (usually for 49 to 56 days, the body weight can reach 2.5 to 3 kilograms). However, if its merchandise generation continues to be reserved for seed use, and there is no strict selection and selection, the offspring (offspring of commodity generations) will be degraded or uneven and develop slowly, which will result in impure varieties. Therefore, in principle, the current excellent meat duck breed should not be reserved for its commodity generation.

2. Inferior bad duck. At present, many people in rural areas buy ducklings from duck traders. If the duck trader sells hatched ducklings earlier or later, or does not meet the requirements of hatching ducklings, the survival rate is generally low and it is difficult to raise them. Big.

3. Dehydrated duck. The ducklings trafficked by the duck traffickers on a long-distance basis may suffer from lack of care and pay attention to replenishment, causing the ducklings to suffer from lack of water for a long time. For such ducklings, the phenomenon of stunting often occurs when they are brought back.

4. Sick duck. There are many ducks flowing in the duck trader's hands. If they do not pay attention to the disinfection of utensils, they can easily cross-infect the ducklings. On the other hand, duck traders sell stalls in the street to sell, and there are many contact persons, which can easily cause the ducklings to become infected with pathogens. Such ducklings will be brought back to support the development of disease due to illness.
