Reasonable duck breeding benefit can be good scientific duck breeding should master five laws

First, the feeding rule of ducks. In natural light, ducks have three most exciting parts of the day, which are in the morning, noon and evening. Accordingly, the following should be done: ⑴ should strengthen early feeding. Liming ducks have a strong appetite, so if they are fed and fed well at this time, the laying ducks will lay more eggs and the meat ducks will gain fat. ⑵ grazes regularly. Grazing combines the best part of duck feeding, and other times let the ducks rest or drive into the water, combining work and rest. If drinking water, administration, mixing and feeding are needed, it is also carried out during the peak feeding period of ducks.

Second, the law of duck laying: the laying peak of laying ducks is from midnight to before dawn, and there are no eggs during the day. In order to increase the laying rate, it should be done: ⑴ 10:00 in the evening, turn off the lights on time, stop lighting, to ensure that laying ducks lay eggs in a quiet environment. ⑵, such as ducks laying eggs later than 5, and the egg head is small, indicating that the concentrate is insufficient, it is necessary to increase the concentrate. ⑶ if ducks lay eggs during the day, it is caused by single feed, insufficient nutrition, early grazing in the morning, high temperature and high humidity in the duck house. The feeding and management conditions of ducks should be improved and the grazing time of ducks every morning should be postponed temporarily (8 o'clock).

Third, duck mating rule: it is reported that breeding ducks usually choose to mate in the morning or evening, in the broad water surface. Therefore, it is necessary to make full use of the mating peak of breeder ducks in the morning or evening to drive them to deeper waters to improve the fertilization rate of breeder ducks.

Fourth, the law of Youshi disease: Youshi disease gets its name from the attack of ducks at you time (17-19:00) every afternoon. During the outbreak of the disease, the ducks were violently agitated and quickly piled up, resulting in some weak ducks being trampled to death, with a mortality rate of about 20%. The disease is caused by transportation stress, so all kinds of stress of ducks before and after long-distance transportation should be reduced as far as possible. Anti-stress drugs were added to the diet 1-2 hours before the first hour of transportation of ducks within a few days after transportation in order to stop the occurrence of Youshi disease in time.

Fifth, the law of immune response: the sensitivity of ducks to immune agents such as vaccines and vaccines changes periodically during the day, the sensitivity is poor in the daytime, and the immune response is slow; when it is close to early morning at night, the epinephrine secretion is the most, and the immune response is the most sensitive. So duck immunization works well in the wee hours of the morning. There are two advantages: ⑴ duck is inactive at night, easy to catch, and has little stress response. ⑵ can produce immunity faster and better when ducks are vaccinated in the early hours of every morning.
