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 born”. In other words, the August of the Lunar Calendar is a difficult time. Through this difficult time, the 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.

Increase feed protein levels

Autumn animals have accumulated energy to ensure the safety of the winter characteristics, ducklings feeding at this time to control long-winding, to prevent excessive fat. Should properly reduce the energy or maintain proper exercise, control the fall duck body 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.

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, we must do a good job in the late autumn cold warm work, it is best to keep the duck house temperature at 13 °C ~ 20 °C. 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, neck is slender, mouth is long and wide, back is wide, chest is wide, pubic bone spacing is 3 to 4 Fingers, pubis and sternum can accommodate 4 fingers to 4.5 fingers, large and soft abdomen, plump but not sagging hips, feathers, swaying, high-production ducks, eliminating low-yield ducks. If the duckling production rate has decreased and moulting has started, artificial forced moulting may be used, ie removing the big hairs of the duck's wings and tail, and feeding the concentrate and the cabbage leaves simultaneously.

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 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 also affect the health of the ducks, resulting in decreased resistance of the ducks, infection of other diseases, and the need to deworm once in the fall.

Do a good job of disease prevention

Autumn is a high incidence of diseases such as duck gizzards, duck cholera, and egg drop syndrome. Therefore, it is necessary to strengthen disease prevention and control, keep the duck house clean and sanitary, and timely remove the excrement; wash sinks and troughs on a regular basis, and regularly perform the duck house and utensils. Disinfection; in strict accordance with the immunization program for vaccination, to prevent the occurrence of disease, to ensure the health of the duck population.
