The technique of using net bed to raise wild duck

1. The choice of duck house: the place with dry terrain, quiet, sufficient water, good ventilation and daylighting and convenient transportation should be chosen. The semi-inclined cement floor can be laid under the net frame of the house to facilitate flushing and cleaning duck dung. The building area is determined according to the amount of feeding. If 1000 animals are raised, the brooding room needs 8m2, the utilization rate of the brooding room is 80%, and the brooding density is 15 per 1m2 net; the middle and adult duck houses are 240m2, and the breeding density is 5 1m2 nets.

2. Breed selection: Beijing duck, Digao duck, Cherry Valley duck and hibiscus duck can be raised in 6 or 8 batches a year.

3. Net bed setting: the net bed in the brooding room and the net bed in the middle and adult ducks are 70cm in height and 3 / 4 in width, and the length is equal to the length of the duck house. Single-column or double-column is fine. The net bed is made of wood frame, and the net is laid with bamboo chips (bamboo broken into wide 2cm, equal to the width of the net bed). The bamboo spacing 1cm of the brooding net bed and the bamboo spacing 2cm of the middle and adult duck net bed. The outer side of the grid is provided with a fence around the 50cm. The spacing of the fence is 5cm, and a sink and a food trough are arranged on the inside of the fence. If possible, the mesh bed can also be woven with No. 8 or No. 10 iron wire with a mesh diameter of about 1cm.

4. Feeding of ducklings: before entering the house, the ducklings should be poisoned to the nursery and paraphernalia. Bromogeramine can be used inside, and lime milk can be used on the outdoor floor. Outsiders are strictly prohibited from entering. The ducklings drink two-part potassium permanganate clear intestine disinfectant within 24 hours after coming out of the shell. After drinking water, you can start training to feed. Pay attention to heat preservation. 35 ℃ at 3 months old, 32 ℃ at 4 days old, 30 ℃ at 14 days old, 28 ℃ at 15 days old, 25 ℃ at 22 days old. In the early stage of brooding (1-10 days old), the temperature at night was 1-2 ℃ higher than that during the day. Humidity requirements: 1: 10 days old, relative humidity 70%, 8 ~ 14 days, 65%, 15 ~ 28 days, 60%. 1-10-day-old ducklings were exposed to 24-hour light (natural light during the day and supplementary light at night). After 11 days of age, natural light during the day, in addition to feeding, drinking water to turn on the lights at night, the rest of the time dark or give dim light, preferably red light. The ducklings from 1 to 10 days old were fed with water 8 times a day, once every 3 hours. Feed water 6 times a day at the age of 11-28, once every 4 hours, and be careful to feed before drinking.

Feed formula: (1) 60% corn, 10% barley, 15% bean cake, 10% fish meal, 3% grass meal, 1.7% bone meal, 0.3% salt. (2) 50% corn, 10% barley, 20% bean cake, 5% wheat husk, 5% rice bran, 8% fish meal, 1.7% bone meal, 0.3% salt. (3) 50% corn, 6% barley, 10% rice bran, 5% wheat husk, 10% fish meal, 2% pine needle meal, 10% bean cake, 5% No. 4 powder, 1.7% bone meal, 0.3% salt. Due to different feed varieties and prices, the proportion can be increased or decreased or adjusted according to the above three formulations.

Epidemic prevention methods: 1% potassium permanganate at the age of 5 days, 2% potassium permanganate at the age of 6-8 days, 2/10000 potassium permanganate at the age of 9-13 days, and 2% potassium permanganate at the age of 14-16 days. If the weather is cold, 1-7-day-old ducklings had better add 8% sugar to their drinking water to increase the calories of the ducklings. In addition, the feces on the net bed should be cleaned twice a day, and the feces under the net bed should be cleared every 3 days. The chicks are disinfected with lime every 7 to 10 days outside.

5. Feeding of Chinese ducks: when ducklings turn into duck net beds at the age of 28 days, sick, paralyzed, disabled and smaller ducks should be eliminated, and the feeding density is 5 / 7 / 1m  2. Light naturally during the day and replenish light when eating at night. In addition to severe winter, doors and windows can be opened all day during the day, and doors and windows should be often opened for ventilation at night and in the severe winter season. Chinese ducks are fed with water 6 times a day, once every 4 hours, with dry and wet feed and drinking water throughout the day.

Feed formula: (1) 48% corn, 15% barley, 8% wheat husk, 10% rice bran or rice meal, 10% bean cake, 5% fish meal, 2.2% pine needle powder, 1.5% bone meal, 0.3% salt. (2) 55% corn, 5% barley, 8% sorghum, 7% wheat husk, 12% bean cake, 4% grass meal, 7.8% fish meal, 1% bone meal, 0.2% salt. In addition, gravel 1~2kg is added to every 100 kg feed in the above two feed formulations.

Epidemic prevention and hygiene: duck cholera can be prevented by feeding 2mg quinolinol per kilogram body weight in feed for 3 to 5 days before and after 35 days of age. The duck net bed should be cleaned once every 2 days, the feces under the bed should be cleaned once every 10 days, and the outside of the duck house should be disinfected with lime every 10 days.

6. Fattening of adult ducks:

1. Fattening by artificial feeding. Meat ducks grow into adults at the age of 6 weeks. If you switch to the feed formula, you can continue to follow the same feeding method, but the weight gain rate is not ideal, and the best way is to fatten the adult ducks. The meat ducks after 6 weeks of age entered the fattening stage. Before fattening, eliminate paralysis, disability, sick ducks and overweight ducklings, and divide them into three categories according to their body weight, with a flat feeding density of 5 ducks per square meter.

Filler formula: (1) 60% corn, 10% wheat husk, 10% rice bran, 4% grass meal, 4% bean cake, 5% rapeseed cake, 5% fish meal, 1.7% bone meal, 0.3% salt. (2) 58% corn, 8% barley, 5% sorghum, 10% bean cake, 5% fish meal, 7% wheat husk, 3% grass meal, 2% pine needle powder, 1.7% bone meal, 0.3% salt. In the above two formulations of feed, sand 2kg should be added per 100kg. Duck filling method: either artificial packing or mechanical packing can be used. When filling, it is necessary to drive gently, catch slowly, and release slowly. The filler is mixed with wet material, and the ratio of water to material is 1.2. 1. The amount of filling depends on the individual size, nutritional status and digestion of meat ducks. the general feeding amount is 0.25~0.3kg per duck per day and 0.4~0.5kg per day in the later period of feeding. Meat ducks should be filled 4 times a day, once every 6 hours, stop water for 30 minutes before filling, and provide adequate clean drinking water for the rest of the time. When filling in summer, fill less during the day and more at night, and fill less or stop filling for individual ducks with small food intake and indigestion, so as to avoid "cramming disease" (that is, paralysis or death).

2. Free feeding and fattening. In order to reduce the labor cost of filling ducks, meat ducks are raised quickly on the Internet, and the method of free feeding can be used throughout the feeding period.

The feed formula ratio of 1-21 days old was as follows: corn 58.8%, bean cake 18%, blood meal 3%, wheat husk 9%, bone meal 0.3%, oyster meal 1.1%, salt 0.3%, fish meal 9%. Each t of compound feed was supplemented with 150g multivitamin, 200g manganese sulfate, 200g zinc sulfate, 100g ferrous sulfate, 20g copper sulfate, 0.1g sodium selenite, 25g Kuaiyuling and 100g methionine. The feed formula of  22-49-day-old is as follows: corn 66.7%, bean cake 9.5%, blood meal 3%, Mai Fu 13%, bone meal 1.5%, oyster meal 1%, salt 0.3%, fish meal 5%. Multivitamin 100g, manganese sulfate 200g, zinc sulfate 200g, ferrous sulfate 100g, copper sulfate 20g, sodium selenite 0.1g, Kuaiyuling 25g, 70% lysine 500g, methionine 400g were added to each t feed.
