(1) Selection of duck breeds Select varieties with good production performance, gentle temperament, small body size, early maturation, rapid growth, low consumption of material, high egg production, high feed utilization rate, strong adaptability, and strong disease resistance. The female ducks stayed excellent for two years and all were updated in the third year. (2) Feed preparation and formula: 50%～60% for cereals, 10%～20% for cakes, 10%～15% for fish meal or soybean meal, 1% for shell powder, 0.5% for salt, and 0.2 for various vitamins % to 0.5% of the ratio to prepare feed. Egg production period reference formula: corn 45%, rice bran 20%, bran 6%, bean cake 10%, fish meal 10%, rapeseed cake 6%, shell powder 1%, bone meal 1%, salt 0.5%, poultry variety Vitamin 0.5%, conditional can also use commercial duck material. (3) Feeding methods Feed mashing and mixing, mixing with water, mixing in hand to form a mass and loosening, generally feeding 4 times per day and night, ie 5 o'clock in the morning, 10 o'clock in the morning, 3 o'clock in the afternoon, 9 to 10 in the evening When feeding each time, the last one should increase the feeding so that the ducks can eat. Each duck fed 125 to 150 grams a day. The ducks in the rest period can feed 2 times a day. (D) timely production of laying ducks before and after the start of production of 150 days, such as premature premature egg production, if too late will affect economic income. The specific approach is to control the green fodder so as to prevent it from propagating the stomach. After 120 days of age, it gradually increases the number of feeds and improves feed quality. (E) After the water is fed, the ducks will be washed off and bathed every day, 4 to 5 times a day in summer, and they can also freely release water. At night, when the ducks are noisy and anxious, they still need to release water once every 20 minutes, and every day at 10:00 a.m. in winter. Each time the water is released from 2 to 3 pm, 5 minutes each time. After the water is released, let the ducks bask in the winter and let the ducks rest in the shade in summer. Avoid exposure. (6) The stronger the libido of male and female collocation ducks, the more eggs are laid. Therefore, ducks should be equipped with enough male ducks. A small herd is reared for every 100 female ducks with one male duck. A large herd of every 200 female ducks is reared with 1 male duck, which can increase the egg production rate by 5% to 8%, and 20 to 30 female ducks for egg-type ducks. Provide 1 drake. Commercial ducks will be protected from harassment during the laying period, the rest period, and the moulting period. (7) Laoya Duck Feeds Laying ducks after 1 year of laying eggs should pay for cod liver oil. Feeding them for 7 days per month will allow Laoya Duck to produce more eggs and prolong the period of high yield. (8) Compulsory moulting ducks in the late summer and early fall seasons should stop moulting. At this time, artificial forced moulting should be carried out by stopping the water in the first two days and stopping the water in the first 3 days. Feed the normal materials in the first 6 days. Half of the amount of water supply; return to normal on the 7th day, in order to promote fast and clean moults so that ducks and ducks unified production. (9) In the litter room, the ground is covered with straw, wheat straw, chaff or wood chips, etc., and the padding is added 1 time every other day to increase the height at the laying place. In combination with the ventilation of the duck house, the cooling of the house can keep the duck house clean and dry. In the summer, a layer of silt or sand can also be laid. (10) Supplementary illumination Autumn and winter seasons Due to the shortening of natural light, the duck's pituitary gland and endocrine glands are reduced, affecting production of eggs, so artificial supplemental lighting must be taken. General requirements The daily continuous light time should reach 16 hours. A 60-watt light bulb can be installed every 30 meters in the duck house. The light bulb is suspended 2 meters from the back of the duck and equipped with a lampshade. Turn on the lights twice a day, sooner or later. Turn on the lights at 4am, turn off the lights at 8am, turn on the lights at 5pm, and turn off the lights at 8pm. The time for switching lights should be strictly fixed, and two 3 to 5 watt low-light bulbs should be installed in each duck house to avoid triggering the alarm. In case of heavy snowfall, heavy fog, rainy days and other shades of light, you must turn on the lights early in the morning and extend the lights off in the morning. If necessary, you can light the whole day. Practice has shown that egg-drinking ducks have a 20% to 25% increase in egg production rate compared to light-filled ducks. (11) Feeding night food Generally, feeding ducks at night will increase egg production by about 1% compared with ducks that do not feed. Therefore, in the fall and winter, ducks should be fed night food. When feeding at night, two things should be noticed: one is to supply enough water, and the other is to feed the protein at night is not too much. (12) Reducing the stress Eggs and ducks have a strong metabolism and are particularly sensitive to contaminated air. Therefore, attention should be paid to ventilation and ventilation. When the ducks play in the water, all the windows in the duck house will be opened. Do not make loud noises in the duck houses at all times, let alone catch bamboo rafts and scare the ducks. Winter should keep warm and cool down in summer to minimize the adverse effects of cold and heat stress on ducks and ducks, so that ducks live in a quiet and comfortable environment. (13) Anti-abnormality When eggs, ducks, individual eggs become smaller, eggshell thinning, prolonged egg production time, feeding, watering feathers to the duck, etc., to take timely measures to prevent and cure. Generally used in the following methods: (1) to improve the quality of feed, in particular to increase protein feed; (2) often drive the ducks, increase the amount of exercise: (3) increase the light; (4) duck house insulation, it is best to add liquid Cod liver oil is fed with 1 ml of spices per day for 3 to 4 days. (14) The indoor and outdoor playgrounds of hygienic duck houses should be cleaned regularly, and food troughs and sinks should be washed and disinfected regularly. The feeds must be fresh and must not be fed with moldy feeds. The drinking water should be clean. The duck house should be ventilated and ventilated to keep the air fresh and prevent ammonia from stimulating the ducks. The bedding should be changed frequently to ensure it is clean and dry. When the ducks are clean and the feathers are dirty, the ducks are immediately washed into the water, otherwise the ducks will become infected due to feathering and even stop production. (15) Regular disinfection 20% of fresh lime milk can be used or 2% of sodium hydroxide or 3% of compound phenol (disinfecting spirit) can be used to sterilize the housing area. Feeding tanks and utensils can be used for killing drugs. disinfection. Green feed and drinking water can be treated with 0.02% potassium permanganate solution. (16) Regular epidemic prevention Do a good job of epidemic prevention. To prevent duck gizzard, duck grubs can be used to attenuate vaccination. Ducklings inoculated after 20 days of age are injected with 0.5 ml per leg muscle. Ducks are injected with 1 ml per pectoral muscle and ducks are injected once every 6 months. To prevent duck cholera, avian cholera hydroxide hydroxide vaccine can be used. The ducklings are injected with 1 ml of each leg muscle after 20 days of age, and 2 ml of breast muscle is injected at 3 months of age, and the immunization period is 75 days. Oxytetracycline can also be used, according to 100 ducks with a dose of 250,000 units of oxytetracycline 5 powder into the feed or dissolved in water, fed 2 to 3 weeks.
