Duck duck manual control moulting method
Moulting is a physiological phenomenon of metabolism of ducks and ducks. Due to different nutritional status and physiological functions, the start and end time of moulting is also inconsistent. If natural moulting is allowed, it will take about 2 months to 3 months to restore egg production. The use of artificially controlled moulting can speed up moulting, shorten the moulting period, and promote consistent production. This is an important measure to increase egg production. In the late stage of laying, when the ducklings production rate will be less than 40%, the feathers will be disorderly, and some ducks will have artificial control of moulting when hair loss occurs. Should be vaccinated before duck moth vaccine, and eliminate thin and low-yield ducks, the specific method is:
Artificially stop laying eggs
Keep the ducks in the pens, do not feed concentrate only water. Due to a sudden change in the law of life and lack of nutrition, the weight of the ducks was significantly decreased and all production was stopped after 2 days to 3 days. Starting from the third day, the average daily feed of 25 grams per duck was gradually increased.
Artificial pullout
After 4 days, the duck plumes are disorderly, and the plumes of the wing feathers are dry and transparent. The wing feathers and tail feathers can all be unplugged. If there is a bleeding phenomenon, it should be removed after 1 to 2 days. The day of pull-feathers should be raised and grazing prohibited to prevent infection.
The feathers and tail feathers of the main wing began to regenerate 7 days to 8 days after the recovery period. Most of the feathers of the back, chest, and abdomen have been removed. At this time, the feed quality must be gradually increased, and the feeding and management methods must gradually return to normal. When the body condition is basically restored, it is necessary to feed more high-protein feeds or to feed a large number of live foods in pastures so that they can start production in advance. Generally, 30 days after pullout, egg production is resumed. The artificial control of moulting is shortened by about 40 days compared with natural moulting, which can significantly increase economic benefits.
