Duck feeding management technology

Feeding management techniques during the brooding period 1. Temperature: The room temperature is generally maintained at 15 to 20°C, and the brooding temperature is set to 30°C. After each 2 days, the temperature can be lowered by 1°C. After 20 days of age, the broiler can gradually transition to room temperature brooding. 2. Humidity: Relative humidity should be controlled at about 70%. Early brooding prevents the humidity from being too low; late humidity should be prevented. In order to keep the ground dry, the floor should be covered with straw or chaff. 3. Density: 40/m2 for 1 to 10 days, 30/m2 for 11 to 20 days, and 25/m2 for 21 to 30 days. After 20 days of age, grazing occurs when the weather is warm and warm. Get up in time at night. Take 50 to 100 as a group. 4. Ventilation: It is necessary to pay attention to ventilation and ventilation while discharging moisture and ammonia. In winter and spring, ventilation windows open during the day and close at night. 5, light: 1 ~ 10 days of implementation of day and night light, daily lighting time of not less than 20 hours. Use 8 W/m2. Artificial light was stopped during the day from 11 to 20 days, and nighttime supplemental lighting was gradually reduced. Natural light was used after 21 days of age. 6, drinking water: 12 hours after the shell into the brooding room, start drinking water, supply the same room temperature and the same temperature of 0.1% potassium permanganate water, warm water before 10 days of age. Drinking water must be guaranteed. B vitamins can be added to drinking water. 7, feeding: 2 to 3 hours after drinking can eat. Mixed diets should be used. Wet powders with water, or crushed granules, can be used to feed less meals. On the 1st to 10th day of age, 7 feedings were performed, including 2 feedings at night, 5 feedings on the 11th to 20th day of the year, 1 feeding at night, and 4 feedings on the 21st day. 8, release water: 1 week old can be placed in shallow ponds or shallow basins, 2 times a day, once in the afternoon, each about 10-20 minutes. After 10 days of age, he is free to launch activities. Drainage is good for growth and cleanliness. The breeding and management technology during the breeding period refers to 31 to 60 days of age. The growth and development of this period is the fastest. At the age of 60 days, the seedlings of the general ducklings and the eliminated ducks are close to the breeding ducks, so they can be listed as meat ducks. 1. The construction of duck houses: The terrain should be slightly higher, the leewards should be sunny, and the houses near the water source should be built. Most of them are semi-open duck houses, with playgrounds and water surfaces. Each duck house is 6 meters long, 4 meters wide and 2.5 meters high. The front wall is open. The area ratio of the duck house, playground and water surface is 1:2:3. The normal density is 10-15/m2. 2, the erection of flood control nets: 50 days when the wing feathers are basically long Qi, began to learn to fly, must be set in the stadium and the water around the top of the metal or nylon net cover, mesh to 2 cm ? centimeters is appropriate to prevent flying sturgeon. Water bamboo poles or metal nets should be deep and at the bottom of the river to prevent absconding. 3. Carefully feeding: The use of food supplements, adhere to regular timing, feeding 3 times a day, and gradually increase the amount of feed (the amount of daily feed is 5% of its weight). If it is used as a back-up duck, the green and blue succulent feed should be increased as appropriate. The dosage should be about 15% of the feed amount to properly control the weight. Prenatal 30 to 40 days can be increased to 55% to 70% green material, coarse material 20% to 30%, fine material 10% to 15%, to control the material to prevent premature birth. 4. Scientific management: Clear up every day, diligently change the bedding and ventilation to keep the water source clean and hygienic. Make sure each duck has an eating position. Weigh the body weight regularly and adjust the diet as appropriate so that the bred duck can reach the standard weight and the meat duck can be listed in time. 5. Full grazing: After 40 days of age, in addition to the harsh weather, pastoralism should be practiced. On the one hand, it can maintain its wildness, maintain the delicate tenderness of the meat, and prevent deterioration of the meat quality; on the other hand, it also exercises its communality and overcomes The lack of nutrients in dietary formulas can be of great benefit in improving physical and planting values. For meat ducks should be reduced to the pastoral or total feeding, increase protein feed, add some feed additives, promote growth, improve meat quality. Breeding Management Techniques for Breeding Ducks Under artificial breeding conditions, American wild ducks reached sexual maturity at around 170 days of age, ducks were slightly earlier than female ducks, and the average annual egg production was about 120. 1. Breeding duck selection: The duck requires a large head, a strong body, a lively, green head and neck, and strong mating ability. Mother ducks require small heads, slender necks, and large eyes. The weight of the duck should not be less than 1.25 kg and the mother duck should not be less than 1 kg. Ducks generally use 1 to 2 years. 2. Breeding proportion: The proportion of male and female ducks mating should be 1:5 to 1:10, depending on the weather and the fertilization rate of the eggs, the ratio should be properly adjusted. 3. Careful feeding: Timely adding bone meal and shell powder during laying; Before the peak of egg production, increase the protein content. Feed 4 times a day. Supplement artificial light 2 to 3 hours in the morning and evening so that the daily light hours reach 15 hours. During the production period, the stability of the feed should be taken care of, and it should not be changed easily; if it needs to be changed, there should be a transition period of 7 days. Water supply and cleaning must be ensured. 4. Scientific management: The duck houses should be kept clean and hygienic. To lay grass around the walls, set up some nests to lure the ducks to lay eggs at night. Open doors and windows in the morning so that late-producing ducks can still produce eggs in the house. Immediately after the duck, pick eggs. For the second year of breeding ducks, the fall is the second production period, at this time can increase the autumn animal husbandry, field feeding, in order to reduce feeding, save costs, should be supplemented after late autumn. Pay attention to the severe changes in the weather, winter cold, summer heatstroke. At the same time, the quiet environment of the duck should be maintained at the same time to prevent all kinds of stress. In the fall and winter nights, you must get up and go to duck to prevent obesity. The breeding density is 8 to 10/m2.
