Autumn climate is suitable, rich feed, adequate nutrition, is a good season for laying ducks. However, the fall duck that hatched in the previous year, after half a year's egg production, the body has fatigued, and the management is slightly careless, and it will stop the production of wool. At the same time, ducks hatched in the early spring mostly start egg production from late September to mid-October, especially ducks that are raised in the wild, because the food that can be found in the late autumn is not much, and often causes nutrient deficiency and reduces egg production. To make ducks more productive, attention should be paid to the following aspects in the autumn management:
1. Adjust the diet and feed it properly. In the autumn, appropriate amount of animal protein feed should be added to ensure the quantity and balance of amino acids, especially essential amino acids such as methionine and lysine, and multi-vitamins should be added. Pay attention to the ratio of calcium and phosphorus and the addition of trace elements. The nutritional level of the general fall duck diet was 18% crude protein, 0.3% methionine, 0.7% lysine, 8% crude fiber, 3% calcium, and 0.6% phosphorus. The amount of fine material fed on autumn ducks should be determined by the rate of laying of ducks. If the ducklings have an egg production rate of more than 50%, fine concentrates may be added. Otherwise, you can feed some green feed, or increase the amount of bran used in concentrates, while reducing the amount of carbohydrates used.
2. Add light. 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.
3. Control the long-term. In the autumn, the food in the wild is abundant, and ducks tend to feed on food. If they are full and do not allow them to exercise properly, it will cause the ducks to lose weight because of over-fertilization. Therefore, they should be allowed to maintain a certain amount of exercise in the fall, maintain a healthy body, and control the body weight to 1.5 to 2 kg in order to promote their eggs and eggs. However, when the ducks go out to exercise or leisurely, they must also pay attention to the autumn rain and cold winds. If it is covered with autumn rain and cold winds, ducks and ducks will cease production, and some will even become ill.
4. Keep warm and warm. 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.
5. Amazing stay excellent. 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.
6. Forced moulting. After late autumn, the egg production of the ducks gradually decreased and the shells became thinner. At this time, artificial forced moulting could be used. That is, remove the big hairs on the wings and tail of the duck, and increase the feed and leaves. Usually 7 to 8 days later, new feathers grow in the wings of the ducks and their tails. At the same time, the feathers of the chest naturally fall off. After about 20 days, the feathers gradually grow and the ducks can resume egg production.
7. Keep the environment quiet. 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 and quietness 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.
8. Insecticide prevention. After a summer, there are inevitable parasites in the digestive tract of ducks. These parasites will not only compete for duck nutrition, but also affect the health of ducks, resulting in reduced resistance of ducks and high vulnerability to other diseases. Therefore, it is necessary to repel insects once in the fall. Autumn is a high incidence of diseases such as duck plague, duck cholera and egg drop syndrome. Therefore, we must strengthen disease prevention and control work, keep the duck house clean and sanitary, and timely remove feces; wash the sink trough regularly to regularly sterilize duck houses and utensils. In strict accordance with the immunization program for vaccination, to prevent the occurrence of disease and ensure the health of the duck population.
