Understanding the physiological characteristics of ducklings Ducklings have three main physiological characteristics: First, rapid growth and development. Second, regulating body temperature is weak and it is difficult to adapt to the external environment. The third is the small size of the digestive organs and weak digestion. Prepare for brooding First of all, we must stock up on fresh, high-quality full-priced feeds. Secondly, the brooding room, feeding equipment and necessary facilities must be fully equipped to ensure that every duckling can eat feed and water. Again, brood chambers, feeding utensils, etc. should be disinfected with 2% caustic soda, dried and rinsed with clean water. Finally, the brooding room is fumigated. Drink water before eating Ducklings do not have hunger after hatching. After 24 hours after hatching, the young ducks have dry hair. They are lively and active. They often make a buzz and start their activities. food. If the ducklings are mentally tired and their eyes are half-opened and half-closed, they are reluctant to exercise and this time has exceeded their open time. Ducklings eat too early, it is easy to damage the digestive organs, affecting the health of ducklings; eat too late, the nutritional supply is not conducive to growth and development. Therefore, the best time for ducklings to eat is between 14-24 hours after hatching. Drink water first and eat again. Adding a proper amount of glucose or vitamin C in drinking water can promote gastrointestinal motility, clear the stomach, promote metabolism, accelerate absorption of remaining yolk, increase appetite, and enhance physical fitness. If you add 1 ton of potassium permanganate in drinking water, you can also play gastrointestinal disinfection. Grasp the feeding method and times Duckling's digestive function is not perfect, so when feeding ducklings, each should not be too much, only to feed six or seven percent full, if a fed too full, easy to cause indigestion, young ducklings gastrointestinal volume is small, and digestion speed Fast, if the number of feedings is too small, the ducklings will be starved for a long time, which will affect the growth and development of the ducklings. Ducklings within 14 days of age were able to reach the duodenum in 5 minutes when they ate freely, started defecation in 2 hours, emptyed in 4 hours, and fed more than 4 hours in intervals. Ducklings Starved. In general, the smaller the ducklings, the lower the food intake and the greater the number of feedings. In the early brooding period, it is necessary to feed less, feed more, feed 6-8 times a day, and feed 1-2 times of night meal to promote duckling activity. Effectively improve insulation Temperature is the main technical measure to cultivate ducklings. Only the temperature is suitable, the ducklings consume less body heat, the growth and development are fast, and the survival rate is high. 1-3 day old 32-34°C, 4-6 days old 28-30°C, 7-10 days old 24-26°C, 11-13 days old 20-22°C. The temperature gradually decreases and the temperature does not change by more than 2°C per day. To raise or lower the temperature under different climatic conditions, the behavior of the duckling should prevail, and the best temperature requirement of the young duckling should be satisfied as much as possible. If the temperature of the duck is low, the ducklings will be afraid of the cold and will get close to the heat source and get warm to each other, often resulting in crushing or suffocation. When the temperature is too high, the ducklings keep away from heat, open their mouths, and increase their drinking capacity. When the temperature is normal, the young Ducks are full of spirit, lively, with good appetite, moderate drinking water, light hair, stretched legs, uniform distribution, silent sleep, eating, drinking, and excretion are normal. Feeding density and grouping The breeding density of ducklings should be appropriate. If the breeding density is too high, the duck house will be damp and the air will be polluted. This will result in poor growth of ducklings and other consequences. If the density is too small, the resources such as space and manpower will be wasted and the benefit will be reduced. The reasonable density for online brooding is 25-30/m2 at 1-7 days, 15-25/m2 at 8-14 days, and 10-15/m2 at 15-21 days, 22- 28 days old 8-10/m2. Ground brood density should be reduced by a factor of two. At the same time, pay attention to the greater density in winter and the summer density can be smaller. Reasonable grouping: Feed 200-300 birds per group and carefully manage ducklings, weak ducks and sick ducks individually. Ensure ventilation Ducklings have a strong metabolism. Excessive concentrations of carbon dioxide and excrement from ducks and harmful gases such as ammonia gas and hydrogen sulfide produced from decomposition of residues will harm ducklings' health. In severe cases, ducklings will suffer from ammonia poisoning and a large number of deaths. Therefore, it is necessary to maintain the air circulation in the brooding room at any time, maintain proper ventilation, maintain fresh indoor air, eliminate excess indoor moisture, keep the duck house dry and clean, and improve the living environment of the ducks, so as to promote the healthy and rapid growth of the ducks. Do a good job of preventing and controlling diseases It is forbidden to introduce ducklings from affected areas. 1. Do a good job of disinfection: pay attention to the disinfection of duck sheds and the environment, as well as the cleaning and disinfection of feed troughs and drinking fountains, and use 2-3 different disinfectants alternately to prevent bacteria from developing drug resistance. 2. Preventive drug use: Focus on the prevention of salmonella, Escherichia coli, and mycoplasma disease in ducklings. Use antibiotics for prevention from 1 to 7 days, but use sensitive drugs. 3. Epidemic prevention: Prepare immunization for duck gizzard, duck viral hepatitis, duck infectious serositis, and bird flu vaccine. When injecting vaccines, add electrolytic multi-dimensional or vitamin C powdered spices. Antibiotics should be stopped for 1-2 days before and after injection.
