Duck duck high-yielding feeding technology

Feeding and management of ducklings Choosing the right brooding period has an impact on improving duckling survival and laying performance. It is generally best to bred early spring ducks at the end of April or early May, or to raise “spring ducks” in June, or raise “autumn ducks” in August. On the second day after the duckling hatched, one-third of the ducklings resembled a feeding state. At this time, they could be fed. Use hard rice cooked with millet, use 10% glucose water, add 10% leeks and rice. Pay attention to the release of water before the water, after the start of eating is the characteristics of duck. Before the feeding, the duck basket should be used for water supply. It is sunny at 13°C-15°C and can be directly drained in cold water for about 5 minutes. In case of rain or cold weather, water is put in the indoor tub. Within 1 week - 2 weeks, water is released every day for about 15 minutes after feeding. Feeding animal feed in a timely manner After the third day of feeding, the ducklings should be fed with 10%-20% of animal feed, such as snails, shrimps, clams, small fish, etc., or fed with 5% of fish meal. To promote the growth of ducklings. From the 3rd day on the green feed supplement, 10%-20% chopped green fodder was added to the feed, or water was freely eaten on the water, such as leaves, aquatic plants, and duckweed. The management of young ducks should appropriately strengthen exercise, promote bone and muscle development, and prevent excessive fat. Every day, the ducks are rushed to do circular motions in their homes, every 5-10 minutes, 2-4 times a day. More contact with ducks, enhance duck guts and prevent frightening groups. Neighborhood lighting, low light lighting. Do a good job of infectious disease prevention. During the young duck period, duck plagues and fowl cholera were mainly prevented. 60 days of age - 70 days of injection of a cholera vaccine, once again 100 days before the injection of avian cholera vaccine, 70 days - 80 days of injection once duck maggot attenuated vaccine. Use ducks more than two years old and inject them once a year. Most of the laying ducks reared before and after the start of production started production at 150 days and reached the peak of egg production at 200 days. The goal of feeding and management in this period is to push the egg production rate to the peak as soon as possible. From the aspect of nutrition, feed quality should be continuously improved according to the rising rate of egg production, increase the nutrient concentration of the diet, increase the number of meals fed, and increase the feed intake to meet the nutritional needs of the laying eggs. The average daily illumination is not less than 14 hours. Light should gradually increase from short to long, until 16 hours per day. The appropriateness of feeding and management at this stage can be observed from the following three aspects: Look at the increasing trend of egg weight. The rapid increase in weight shows that it is well maintained. Look at the rising rate of egg production. At the latest by the age of 200 days, the egg production rate should reach about 90%. Look for changes in weight. The body weight maintained at the time of opening shows that the husbandry was properly managed. It is difficult to maintain the peak of egg production from the feeding and management in the late stage of production until the end of laying, but for the high-yield species, if it is properly managed, it can maintain an egg production rate of about 80%. To achieve such a level, the post-feeding management work must be done carefully. The main points of feeding and management are: According to the weight and the egg production rate, the quality of the feed and the amount of feed should be determined. The feed should not be increased or decreased blindly. Keep light. Keeping 16 hours of light every day cannot be reduced. Managed properly. Put more and less clearances to promote sports. Observe changes in eggshell mass and egg weight. If there is a drop in the quality of egg shells or a reduction in egg weight, fish liver oil and inorganic salt additives can be added. The feeding and management of egg-laying ducks in autumn and winter in September and October is a critical period for feeding ducks. It can not only maintain the egg production rate of more than 80%, but also has the danger of a sharp drop. Artificial light is added to maintain the light for 16 hours per day. Overcoming the effects of climate change, especially before the arrival of cold air, try to make the microclimate change within the house not too large. Appropriately increase nutrition and supplement animal protein feed. Select one duck group to separate ducks that have stopped laying eggs, or to eliminate them early, or force moulting. Feeding and management techniques in winter points to improve the level of metabolic energy in feed, reaching 2900 kcal to 3000 kcal/kg, crude protein 20% to 22%. Green feed or eggs with multi-dimensional guarantee normal supply. Cold insulation. The duck house is surrounded with cold grass curtains to prevent thieves from getting windy. During the winter, litter can only be added and kept dry, which will help increase the temperature. In the morning, the ducks should be released late in the morning and the ducks should be closed early in the evening. Usually, there is less water. In the morning and afternoon, when the temperature is high, the water will be discharged once every 10 minutes. Perform artificial light supplements for 16 hours per day. It is advisable to increase the breeding density per unit area of ​​8-9 feathers per square meter. Ducks are best fed warm water. (Source: China Animal Husbands, Kong Lingwen, Li Lianren)
