From hatching to 3 weeks of age, the ducklings are brooded. Careful feeding and management should be performed according to the conditions necessary for the growth of the ducklings. I. Selection and transportation of ducklings The body of the duck is good or bad and directly affects the brooding effect. Ducklings have the same hatching time, normal development, bright hair color, great eyes, good abdominal contraction, and struggle in the hands. Weak young duck hair dry, nail umbilical, large abdomen umbilical, soft, weak, too much weight or too light. When ducklings are transported, it is advisable to use 80-100 sticks per basket, which is filled with straw and can also be used to pack ducklings in cartons. Cold weather should be covered with a thin cloth or a thick cover. Find out how the ducklings play, and unplug them in time. Avoid sun and rain during transportation. To purchase ducklings from a long distance, it is best to use the trick. To calculate the time for starting a cricket, it is best to brood just after the quail eggs arrive at their destination. Second, brooding methods Cage raising and brooding. The cage size is 15080 cm. At the end of the net, a 11 cm welded wire net or a laminated plastic net is used, and a 1.51.5 welded wire net is used for the side net. The cabinet is erected with a 40-60 cm high bracket. Ground raising brooding method. Laminate quicklime on the clean ground, cover with 8-12cm thick bedding, and use a 60cm high bamboo fence to form a small circle of 2m2. Heating can use a variety of heat sources to meet the principle of ambient temperature required for ducklings. Third, the brooding environment 1. Temperature. Temperature is the key to brooding. One week of age is 30-28°C, two weeks of age is 28-26°C, and three weeks of age is 26-24°C. After three weeks of age, it can be gradually raised to normal temperature. Regardless of spring or summer, the nighttime temperature should be 1-2°C higher than the daytime. 2. Humidity. The relative humidity during brooding should be maintained at 60%-65%. Humidity is too high, feathers are wet, and the normal heat dissipation of the duck body is affected; the humidity is too low, and dust is easily raised in the room, making ducklings more susceptible to respiratory diseases. 3. Ventilation. As the ducklings have higher body temperature, quicker breathing, more metabolism, and more excretions, and the room temperature is higher, the indoor air is polluted. Therefore, it is necessary to pay attention to regular air exchange so that the air in the house is fresh and clean. 4. Light. Adequate light can increase duckling vigor, stimulate appetite, help digestion, and keep the house warm and dry. If the lighting time is not enough during the day, artificial light can be used. The 1-3 day old brooding room should have day and night light. 5. Density. At the age of one week, cages were raised to 50 feathers per square meter, and the ground was raised at 30-40 feathers per square meter; at the age of two weeks, it was 40 and 25 feathers respectively. Ducklings have a higher survival rate in small groups. Generally suitable for each group of 60-100 feathers, with the increase of age can gradually merge, large groups of breeding. Fourth, wild ducklings feeding and management 1. Eat and drink. Ducklings should start eating before drinking. The ducklings were fed with 0.1% potassium permanganate water after entering the brooding house. For ducklings transported in long distances, they must be fed with 5% sugar cane, and the water temperature should be similar to room temperature. Before the ducklings enter the house, the ground of the brooding house should first be washed and disinfected with 10% lime water, and then be disinfected with 1:300 germ poison spray. Indoors should be heated 1-2 days in advance. For starters, soaked rice grains can also be used. Compound feeds can also be used. Spread the feed evenly on a plastic sheet to induce food. Feeding should pay attention to less feed Tim, in order to prevent feed rancidity and deterioration of palatability and nutritional value. Feeding 7-8 times a day for 1 week, 6 times for 2 weeks, and gradually decrease with increasing age. 2. Adjust the water. When the weather is clear and the outdoor temperature is around 20°C, ducklings should be released as early as possible, so that the ducks adapt to the domesticated ecological environment and enhance their physical fitness. In summer, water can be released at 1 week of age, and it can be postponed to 2-3 weeks of age in spring and autumn. The release of water was done after eating. The first time of water release is slightly shorter, generally 15-20 minutes, after which the frequency of water release and the time of water release are gradually increased. After the water is drained, let the ducklings dry feathers on the grass and then return to the duck house after a short break.
