Duck breeding technology in greenhouse;
1. The location and construction of the duck house should be located in Gao Shuang, with flat and solid ground and sufficient sunshine, close to the water source (water depth 1-2m), facing south and far away from the bungalows. The herringbone roof of the duck shed is 4-5 meters high, and the eaves around it are 1.8 meters high. There are two doors 1.5 meters wide on the water side, which should be a sports ground. Building materials can be framed with bamboo and covered with linoleum or straw. A bamboo shed fence with a height of 60 cm is set around the sports ground, and a trough and sink are set for every 100 duck in the sports ground. The duck house covers an area of 6-8 ducks per square meter. Generally, it is more suitable to raise about 65,438+0,000 ducks in a shed, and one end of the house is reserved for feed warehouse and breeder house.
Second, the selection of laying duck varieties should choose varieties with good production performance, docile temperament, small size, early maturity, rapid growth and development, less materials, more eggs, high feed utilization rate, good adaptability and strong disease resistance.
Third, the feeding management of laying ducks should be classified according to the different growth habits of ducklings, adult ducks and laying ducks in the feeding process.
1. There are five main links in the management of ducklings.
① Drinking water: It should be carried out after ducklings hatch 12-24 hours, and the water temperature is 20-25℃. A variety of vitamins and drugs, such as norfloxacin, can be added to the water to enhance the physique of ducklings and prevent duck bacterial enteritis. ② Start eating: After eating, you can feed 60% full broken rice washed with water, and then gradually add duckling feed, feeding 6-8 times a day until 1 month old.
③ Heat preservation: the indoor temperature is kept at 27-30℃ in the first week, and then it is decreased by 3℃ every week, and it is kept at about 20℃ after 3 weeks.
(4) Drain water: drain water twice a day for half an hour in 1 week, with the water temperature not lower than 15℃, and then gradually extend it.
⑤ Strengthen management: sweep the duck house frequently, change the padding frequently, eliminate sick chicks, keep ventilated and dry, and pay attention to disinfection, drinking water hygiene and rat prevention.
2. Breeding and management of breeding ducks. Generally, duck feed is fed after 1 month old, and the feed is composed of grain feed (mainly corn or rice) accounting for 50%-60%, cake feed (mainly soybean meal and rapeseed meal) accounting for 10%-20%, and protein feed (mainly fish meal and soybean meal) accounting for10%-0%. In addition, 0.2%-0.4% salt and 0.2% multivitamins should be added. Ducks can eat freely, release water twice a day, and keep the duck house clean until they are 70 days old.
3. Laying duck feeding management focuses on "five customs".
① Good feeding: Shao ducks generally start laying eggs in about 80 days, and laying ducks can be fed with complete feed or self-made feed if conditions permit, but when the laying rate reaches about 70%, the crude protein in the diet should be kept at about 18%, and generally fed four times a day (7: 00 am, 6: 438 pm 12: 00 pm)
(2) Turn off the water properly: water can be drained from 9: 30 am to 1 0: 30 am and from 3: 30 pm to 4: 30 pm every day, each time for half an hour to 1 hour, which can be extended in summer and slightly shorter in winter.
③ Turn off the lighting: supplement the lighting at night. The initial lighting should be no less than 14 hours every day and night, and then gradually increase to 16 hours. At the same time, according to the length of natural light, apply low light (15-25w bulb) in summer, constant light (25-40w) in autumn and increased light (40-60w) in winter and spring, and gradually change the light, so that ducks have an adaptation process.
④ Strengthen management: collect eggs on time every morning and add a small amount of bedding grass every night. Pay attention to ventilation for heatstroke prevention and cooling in summer, and clean up feces in time. Pay attention to heat preservation in winter, and the interval between cleaning feces can be slightly longer.
⑤ Good elimination: Generally, the production performance of high-laying ducks can lay 280-300 eggs every year, and they will be eliminated after one year of opening.
Fourth, do a good job in duck disease prevention and control. Duck disease will occur all year round, so we must adhere to the policy of "prevention first, early treatment, and simultaneous prevention and treatment".
