Meat bed net breeding technology
1. The choice of duck house: The place should be dry, quiet, well-watered, well-ventilated, and easily accessible. A semi-inclined concrete floor can be laid underneath the sheer network to facilitate flushing and sweeping duck dung. The building area is determined by the amount of feeding, such as raising 1 000, the brooding room needs 8m? 2, the brooding room utilization rate is 80%, the brooding density is 15 per 1m? 2 nets, and the middle and adult duck houses are 240m? 2 The density is 1m? 2 net beds 5 only.
2. Variety selection: Beijing Duck, Degao Duck, Cherry Valley Duck and Furong Duck should be adopted, and 6-8 batches can be raised each year.
? 3, net bed settings: brooding room net bed and duck net bed height 70cm, width 3 to 4, the length of the duck and the same length. Single or double row. The net bed is made of wooden frames, and the net is made of bamboo pieces (broken bamboo is 2 cm wide and equal to the width of the net bed). The bamboo spacing of the brooding net bed is 1 cm, and the bamboo spacing of the middle and adult duck net bed is 2 cm. A fence of about 50 cm is provided outside the grid. The distance between the fences is 5cm. The tanks and troughs are set inside the fence. If possible, the net bed can also be braided with 8 or 10 wire meshes with a mesh diameter of about 1 cm.
? 4, ducklings feeding: Before the ducklings into the housing, the brooding room and brooding utensils to be poisoned, can be used within the Xinjieer out, available on the outdoor lime milk. It is forbidden for foreigners to enter. The ducklings consumed potassium permanganate bowel disinfectant within 24 hours of shelling. After drinking water, you can start training for eating. Pay attention to insulation. 1 to 3 months 35°C, 4 to 32°C, 8 to 14 days 30°C, 15 to 21 days 28°C, 22 to 28 days 25°C. In the early brooding period (1 to 10 days old), the nighttime temperature is 1~2°C higher than that during the day. Humidity requirements: 1 to 10 days of relative humidity 70%, 6 to 14 days of age 65%, 15 to 28 days of age 60%. 1 to 10 days old ducklings are given full sunlight for 24 hours (natural light during the day and supplementary light at night). After 11 days of age, the natural daylight during the day, in addition to feeding at night, drinking water to turn on the lights, the rest of the time dark or give dim light, preferably red light. 1 to 10 days old ducklings were fed 8 times a day and fed once every 3 hours. 11 to 28 days of feeding 6 times a day, every 4 hours, pay attention to the first feeding after drinking.
Feed formulation: (1) 60% corn, 10% barley, 15% soybean cake, 10% fish meal, 3% grass powder, 1.7% bone meal, and 0.3% salt. (2) 50% of corn, 10% of barley, 20% of soybean cake, 5% of Maifupi, 5% of rice bran, 8% of fish meal, 1.7% of bone meal, and 0.3% of salt. (3) 50% of corn, 6% of barley, 10% of rice bran, 5% of mefold, 10% of fish meal, 2% of pine needles, 10% of soybean cake, 5% of No. 4 flour, 1.7% of bone meal, and 0.3% of salt. Due to the different feed varieties and prices, each place can increase or decrease or adjust the proportion of the above three formulas.
? Prevention of disease: 1 to 5 days of age with 2% potassium permanganate drinking water; 6 to 8 days of age with two-tenths of drinking water Traning; 9 to 13 days of age and then drinking water with potassium permanganate; From 14 to 16 days of age, drink with 2/10,000 Teriol. If the weather is cold, ducklings from 1 to 7 days of age are advised to add 8% sugar in drinking water to increase the calories of ducklings. In addition, the excrement on the bed should be cleaned twice a day, and the excrement under the bed should be removed every 3 days. Brooders are disinfected with lime every 7 to 10 days outside.
5, feeding ducks: ducklings 28 days of age when the ducks into the net bed, to eliminate disease, sickle, residual and individual smaller ducks, breeding density of 5 ~ 7 / 1m? 2 . Natural light during the day, fill light at night feeding. In addition to the harsh winter, doors and windows can be opened throughout the day during the day, and ventilation and ventilation are often required at night and during the winter season. Ducks are fed six times a day, every 4 hours, and the feed is dry and wet, providing drinking water throughout the day.
Feed formulation: (1) 48% corn, 15% barley, 8% momowa, 10% rice bran or rice flour, 10% soybean meal, 5% fish meal, 2.2% pine needle powder, 1.5% bone meal, and 0.3% salt. (2) Corn 55%, barley 5%, sorghum 8%, wheat husk 7%, bean cake 12%, grass powder 4%, fish meal 7.8%, bone meal 1%, salt 0.2%. In addition, in the above two feed formulations, 1 to 2 kg of gravel was added per 100 kg of feed.
• Epidemic prevention and hygiene: Before and after 35 days of age, ducks are fed with 2 mg olaquindox per kilogram of body weight in the feed for 3 to 5 days, which can prevent and cure duck cholera. The duck net bed should be cleaned 1 time in 2 days, and the feces in the bed should be cleaned 1 to 7 days. The duck house should be sterilized once every 10 days with lime.
? 6. Duck fattening:
? 1, artificially fed fattening. Meat ducks are 6-week-old and grow into ducks. If they use feed formulas, they can continue to use the same feeding method in middle ducks. However, the weight gain rate is not ideal. The best method is to fill ducks with fat. After 6 weeks of age, the meat duck enters the filling stage. Before replenishing fertilizer, weeds, crickets, sick ducks and underweight ducks were sorted out and divided into large, medium and small categories according to the body weight of the ducks. Five breeding stocks per square metre were kept at a flat density.
• Filler formulas: (1) 60% corn, 10% momove, 10% rice bran, 4% grass powder, 4% soybean cake, 5% rapeseed cake, 5% fish meal, 1.7% bone meal, and 0.3% salt. (2) 58% of corn, 8% of barley, 5% of sorghum, 10% of bean cake, 5% of fish meal, 7% of momowa, 3% of grass powder, 2% of pine needle powder, 1.7% of bone meal, and 0.3% of salt. In the above two formula feeds, 2 kg of sand is added per 100 kg. Duck feeding method: artificial filler or mechanical filler can be used. When filling, it is necessary to lightly catch, slow-catching, slow-release, and use wet mixes for filling. The ratio of water to feed is 1.2:1. The amount of filler depends on the individual size of the duck, nutritional status and digestive conditions, the general amount of food per duck per day 0.25 ~ 0.3kg, filling the late 0.4 ~ 0.5kg per day. Fill the duck four times a day, once every six hours, stop filling for 30 minutes before filling, and provide sufficient clean drinking water for the rest of the day. When filling in the summer, fill in less during the day and fill in at night. Indigestion ducks need to fill in less or stop filling in order to avoid "ducking duck disease" (ie disability or death).
? 2, free to feed fattening. In order to reduce the labor cost of feeding ducks, ducks are quickly bred online and free-feeding methods can be used throughout the feeding period.
1 to 21 days of feed formulation ratio: corn 58.8%, 18% soybean cake, blood meal 3%, coat 9%, bone meal 0.3%, lotus root starch 1.1%, salt 0.3%, 9% of fish meal. Each t of compound feed was added: poultry multi-dimensional 150 g, manganese sulfate 200 g, zinc sulfate 200 g, ferrous sulfate 100 g, copper sulfate 20 g, sodium selenite 0.1 g, fast-breeding 25 g, and methionine 100 g. The feed formula for 22 to 49 days of age was: 66.7% for corn, 9.5% for soybean cake, 3% for blood meal, 13% for Mafu, 1.5% for bone meal, 1% for lotus root starch, 0.3% for salt, and 5% for fish meal. 100 g of multi-dimensional pigment, 200 g of manganese sulfate, 200 g of zinc sulfate, 100 g of ferrous sulfate, 20 g of copper sulfate, 0.1 g of sodium selenite, 25 g of fast-breeding spirit, 70% lysine 500 g, and 400 g of methionine were added per t of feed.
