The use of net bed feeding can shorten the production cycle, reduce the disease of ducks, and greatly increase the breeding efficiency compared with traditional feeding methods. Traditionally, it takes about 65 days to raise 2.5 kg of live ducks. This method only takes 40-56 days. The specific operations are described below for reference by farmers. The construction of duck houses in duck houses should be built in a place where the terrain is dry, quiet, with sufficient water, good ventilation and lighting, and convenient transportation. A semi-inclined concrete floor can be provided below the grid to facilitate the flushing and sweeping of duck dung. The construction area is determined according to the size of the breeding stock. For example, 1000 ducks are raised, the brooding room needs 8 square meters, the brooding density is 15 per square meter net bed, and the middle and adult duck houses are 240 square meters, and the rearing density is 5 per square meter. only. Selection of breeds should adopt Beijing duck, Degao duck, Cherry Valley duck and Hibiscus duck, which can raise 6-8 batches a year. The net bed is set to be 70 cm high and 3-4 meters wide in the brood room net bed and the middle and duck net beds, and the length is equal to the length of the duck house. Single or double row. A wooden frame is used for the net bed, and the net is made of bamboo pieces (broken bamboo is 2 centimeters wide and the length is 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 with a height of about 50 cm is provided on the outside of the grid. The distance between the fences is 5 cm, and the sink and trough 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. Ducklings Feeding ducklings Before entering the house, the brooding room and its hatchery utensils must be sterilized. The interior can be used as a benzalkonium chloride solution and the outdoor floor can be sterilized with lime milk. It is forbidden for outsiders to enter. The ducklings consume two-tenths of potassium permanganate bowel disinfectant within 24 hours of shelling. After drinking water, you can start training for eating. Should pay attention to insulation, 1-3 days of 35 °C, 4-7 days of 32 °C, 8-14 days of 30 °C, 15-21 days of 28 °C, 22-28 days of 25 °C. In the early brooding period (1-10 days old), the nighttime temperature is 1-2°C higher than the daytime. Humidity requires 1-10 days of relative humidity 70%, 8-14 days of age 65%, 15-28 days of age 60%. 1-10 day old ducklings are exposed to full sunlight for 24 hours (natural light during the day and supplementary light during the night). After 11 days of age, 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. Ducklings on days 1-10 are fed 8 times a day and fed once every 3 hours. Feeding water 6 times on 11-28 days, once every 4 hours, pay attention to drinking water after feeding. Feed formulation: (1) 60% of corn, 10% of barley, 15% of bean cake, 10% of fish meal, 3% of grass powder, 1.7% of bone meal, and 0.3% of salt. (2) Corn 50%, barley 10%, bean cake 20%, bran 5%, rice bran 5%, fish meal 8%, bone meal 1.7%, salt 0.3%. (3) Corn 50%, barley 6%, rice bran 10%, bran 5%, fish meal 10%, pine needle powder 2%, bean cake 10%, No. 4 powder 5%, bone meal 1.7%, salt 0.3%. Due to the different feed varieties and prices, each place can increase or decrease or adjust the proportion of the above three formulas. Anti-epidemic method: Drink water with 2% potassium permanganate for 1-5 days; reuse 0.02% potassium permanganate for drinking water at 6-8 days; reuse 0.02% potassium permanganate for drinking water at 9-13 days; 14-16 Reuse 0.02% furazolidone at day age. If the weather is cold, 1-7-day-old ducklings are advised to add 8% sugar in drinking water to increase the calories of the 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. The brooding room is disinfected with lime once every 7-10 days. When the ducklings were reared on ducklings at the age of 28 days, the diseased ducks, quail, and individual smaller ducks should be eliminated. The breeding density was 5-7 birds per square meter. 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% bran, 10% rice bran or rice flour, 10% soybean meal, 5% fish meal, 2.2% pine needle powder, 1.5% bone meal, 0.3% salt. (2) Corn 55%, barley 5%, sorghum 8%, bran 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, add 1-2 kg of gravel per 100 kg of feed. Epidemic Prevention and Hygiene: Before and after 35 days of age, ducks are weighed in the amount of olaquindox in the feed according to the weight of the duck group. Feeding them for 3-5 days can prevent and cure duck cholera. The duck net bed should be cleaned 1 time in 2 days. The stool under the bed should be cleaned once every 7-10 days. Every 10 days outside the duck house should be disinfected with lime once. 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 overweight ducks were sorted out and divided into large, medium and small categories according to their body weight. The average breeding density was 5 per square metre. Filler formulations: (1) 60% corn, 10% bran, 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 bran, 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 should be added for every 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, nutritional status, and digestive status of the duck. The average daily feed intake is 0.25-0.3 kilograms per duck per day, and 0.4-0.5 kilograms per day per day during the late filling period. Fill the duck four times a day, once every six hours, before filling, stop for 30 minutes, and provide enough water for the rest of the day. Fill in the summer, fill in less during the day, fill in at night, and eat small and digestive food. The poor ducks should fill in less or stop stuffing so as to avoid "ducking duck disease" (ie, disability or death). Free-feeding and 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 breeding period. Feed ratios of 1 to 21 days of age were 58.8% for corn, 18% for soybean cake, 3% for blood meal, 9% for bran, 0.3% for bone meal, 1.1% for lotus root starch, 0.3% for salt, and 9% for fish meal. Added per ton of compound feed: poultry vitamin 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, methionine 100 g . The feed formulation for 22-49 days of age was: 66.7% of corn, 95% of soybean cake, 3% of blood meal, 13% of bran, 15% of bone meal, 1% of alfalfa meal, 03% of salt, and 5% of fish meal. Add 100 grams of multi-dimensional food, 200 grams of manganese sulfate, 200 grams of zinc sulfate, 100 grams of ferrous sulfate, 20 grams of copper sulfate, 0.1 grams of sodium selenite, 25 grams of fast-breeding spirit, and 70% of lysine 500 per ton of feed. Grams, methionine 400 grams.
