In autumn, the temperature gradually decreases, the temperature difference between day and night is large, and the sunshine time becomes shorter. The fall duck that hatched in the previous year, after half a year's production of eggs, has been very tired. If there is a slight carelessness in management, the moult will be discontinued.
Ducks that hatched in early spring began to lay eggs from late September to mid-October. The weather gradually became cooler and the temperature difference between day and night was too great. Especially for ducks reared in the wild, few foods could be found in late autumn. Insufficient nutrition will affect the production of eggs, so that the production of ducks will be "falling eggs." Therefore, the rural rearing ducks have the saying “Spring is afraid of four, autumn is afraid of eight, and eight is over, and birth is bornâ€. In other words, the August lunar calendar is a difficult time to tide over this difficult time. Ducks can always produce eggs until the lunar month, and it is possible to keep the egg production rate above 80%. Therefore, management should be strengthened in the autumn, pay attention to nutrition regulation, keep the environment stable, and delay moulting as much as possible to improve the production level of ducks.
Guaranteed lighting time
The natural light time in autumn is gradually shortening, which is not conducive to maintaining vigorous reproduction of ducks and ducks. To supplement artificial lighting, the daily light time can not be less than 16 hours, and the light intensity is stabilized. A 20-square-meter duck house is generally equipped with a 40-watt light bulb. A lampshade is placed over the bulb, and the distance between the lamp and the light is the same. The height of the suspension is 2 meters to keep the bulb clean. Light can be turned on in the morning when the light is on, off the lights at sunrise, turn on the lights at sunset, make up for the 16 hours light off.
Increase feed protein levels
Autumn animals have the property of accumulating energy and ensuring safe winterization. The ducklings are raised at this time to control the long-winding and prevent excessive fat. Should properly reduce energy or maintain proper exercise, control fall duck weight within 2 kg. At the same time, the protein content of the diet should be properly increased, and the crude protein content of the diets of captive ducks should be increased to over 18%. Free-range ducks should be properly supplemented with protein feeds so that it can consume enough protein to meet the egg production needs. This will ensure that the fall duck will produce more eggs from the summer heat to the winter solstice. In addition, to properly supplement the inorganic salt feed, it is best to set mineral feed bowls (1 bone meal + 3 shell powders) in the duck house, allowing any duck to eat freely.
Doing cold work
When the wind blows once in autumn, it will drop once. The sudden drop in temperature will lead to a significant drop in the egg production rate. The change in the microclimate of the duck house should be reduced as much as possible during production. Therefore, it is best to keep the temperature of the duck house at 13~20°C in order to prevent cold and keep warm in the late autumn. At the same time, keep the duck and duck shelter dry.
In autumn, it is a rainy season. The playground is prone to accumulation of water. The litter in the duck house is prone to dampness and mildew. Measures must be taken to reduce the humidity in the house and prevent the litter from being too moist.
Eliminating low-producing ducks
In the fall, ducks that have stayed for more than two years must be poorly preserved, and those who choose to stay are small, eyes are big and small, the neck is slender, the mouth is long and wide, the back is wide, the chest is wide, and the pubic bone spacing is 3 to 4 digits. The pubic and sternal ends can accommodate 4 to 4.5 fingers, the abdomen is large and soft, the hips are full and do not droop, the feathers are sloppy, the walking ducks are swaying, and low-yield ducks are eliminated. If the duckling production rate has been reduced, moulting begins. At this time, artificial forced moulting can be used, that is, removing the big hairs of the duck's wings and tail, and feeding the concentrate and the cabbage leaves simultaneously. After 7 days, the ducks had new feathers in their wings and their tails, and the chest feathers naturally fell off. After 20 days, the feathers gradually grew and recovered.
Operating procedures and keeping environment stable
There is a regular pattern of egg-laying ducks. After eating, they bathe and rest. They run around and do not move at rest during the night. Therefore, to maintain the stability of the operating procedures and feeding environment, do not disturb the law of duck life, so that ducks and ducks maintain good egg production performance.
Deworming
After a summer, the ducks inevitably have parasites that enter the digestive tract. These parasites will not only compete for duck nutrition, but will also affect the health of the ducks, resulting in reduced resistance of the ducks, infection of other diseases, and the need to deworm once in the fall.
