Breeding technology of Yuanyang 1 site selection
The plain area is high and dry, north to south; In mountainous and hilly areas, the site should be built in the south or southeast of the hillside. Sandy loam is the best soil for drainage after rain. Yuanyang duck house should have good ventilation, lighting and drainage, which can avoid the northwest wind and be warm in winter and cool in summer.
2 feeding methods
The male-female ratio of mandarin ducks and ducks is 1:3-5, which can be mixed, kept in captivity and stocked, and can be simplified because of its ugliness. There is a pool and a proper playground in the pen, and there is a nest for laying eggs in the house.
3 Feeding management
Meat mandarin ducks are simple to raise and convenient to manage, and can be raised in water, dry and captive. Its temperature and cold tolerance and strong adaptability can be cultivated all over the country. Eating habits are very diverse, including grass, vegetable leaves, crop leaves, leaves, corn, bran, rice bran, bean dregs, beer dregs, miscellaneous cakes, insects and so on. Strong disease resistance, no catastrophic diseases such as plague.
3. 1 Ducks (0-6 weeks old) Ducks are sensitive to temperature within 1-3 days after hatching and like to sleep well. They should keep the temperature not lower than 30℃ for 3 days, and then gradually cool down. /kloc-you can start eating in 0/8-24 hours. Put the feed in a shallow dish and let it eat freely. Feed it five times a day, four times a day and 1 time at night. Take out 16 hours from the shell, drink 0.02% potassium permanganate solution 1-2 days, and then drink clean water directly. Feed formula: corn flour 56%, bean cake 18%, bran 10%, rice bran 10%, bone meal 2%, fish meal 2%, yeast powder 1.5%, salt 0.5%, and other vitamins and trace elements. 1-3 weeks old should be supplemented with artificial light at night, and natural light should be used after 4 weeks old. Pay attention to changing mat grass frequently, and remove mat grass after 2-3 years old.
3.2 China ducks grouping (7- 10 week old): each group 100-300 ducks, with a density of 5-8 ducks per square meter. Feed formula: corn flour 45%, bean cake 10%, bran 15%, rice bran 15%, grass meal 9%, bone meal 2%, fish meal 1.5%, yeast powder 2% and salt 0.5%.
3.3 Adult ducks (1 1-24 weeks old) were selected, and large and strong male and female ducks were kept, with the male-female ratio of 1:3-5. Reserve ducks should be restricted to feed, reduce the nutritional content of feed, properly control their weight, and prevent overweight from affecting their fertility. The weight of the female duck is controlled at 2.3-2.8kg, and that of the male duck is 4-5kg. The daily feed intake of each animal is 100- 150g, and 25-50g green feed can be fed every day. Feed formula: corn flour 54%, bean cake 17%, bran 18%, grass meal 3%, fish meal 3%, bone meal 3%, yeast powder 1.5%, salt 0.5%, other vitamins and cloud elements.
Epidemic prevention and elimination of diseases
Before entering the house, thoroughly disinfect the house and utensils 1 time. 15%- 18% limewater made of quicklime is used to thoroughly disinfect the walls, floors and utensils of Yuanyang duck house 1 time to cut off germs. Antibacterials are added to the diet irregularly to prevent epidemics and eliminate diseases.

Duck feeding management 1 duckling feeding management
1. 1 brooding conditions
1. 1. 1 The temperature and humidity of ducklings are sensitive to temperature, and the shed temperature of 1 ~ 2 days old should not be lower than 32℃. After the third day, it is mainly to observe the dynamics of ducklings and adjust the temperature from cold to hot. The suitable temperature is that the ducks are evenly dispersed and look natural. The relative humidity of ducklings should be kept at 60% ~ 70% and 50% ~ 55% when they are 2 weeks old.
1. 1.2 ducklings can be raised on the ground or online. The former has the advantages of simple equipment, low investment and good fat accumulation, while the latter does not touch feces, saves padding and has good environmental sanitation conditions, so farmers can choose flexibly.
1. 1.3 preparation before hatching
① Prepare duckling feed (which can be replaced by meat duck pellet feed or broiler feed), and add 200mg/kg oxytetracycline or 100mg/kg furazolidone to the beverage to prevent white dysentery. (2) Prepare enough padding, and you can choose sawdust or broken hay.
(3) Clean the duck house and all kinds of tools and thoroughly disinfect them.
(4) Supply the temperature of duck house 12 hours before the house is closed, so that the room temperature can meet the requirements of brooding standards. 1.2 duckling management
1.2. 1 After the ducks are hatched in groups, the ducklings should be reasonably grouped according to the hatching time, physical strength and weight, so that the strong ducklings and weak ducklings can be raised separately, and the number of ducklings should be 200 ~ 300. At the age of 8 days and 15 days, the ducks should be grouped according to the strength of the flock to improve the uniformity of the flock.
1.2.2 Drink water before eating, and the ducklings can be put into a warm water basin with a depth of 1cm for free suction and washing about 12 hours after hatching. You can feed 1 hour after drinking water. You can choose crushed corn kernels or granular substances to sprinkle on dark plastic sheets and let them eat freely. The basin is placed next to the cloth, which is convenient for drinking water or gargling at any time. As the ducklings grow up, the distance between the basin and the dregs can save feed.
1.2.3 Newborn ducklings should be fed less and more, so as to avoid one-time overfeeding and keep their appetite strong. For weak chicks, be patient to lure them to feed. Feeding in a trough after 3 days, and feeding regularly at the age of 6 days, 6 ~ 8 times a day.
1.2.4 lighting scheme: the duck house can use 40W incandescent bulbs every 1 5m2, 1 ~ 3 days for 24 hours, 4 ~ 7 days for 23 hours, and then decrease1hour every day until natural lighting is adopted.
1.2.5 Keep the pens clean and dry. During the brooding period, it is necessary to do a good job in cleaning the pens, clean up the accumulated feces in time, disinfect them regularly, prevent outsiders from entering the duck house, and do a good job in preventing infectious diseases. 2. Feeding and management of ducks and mandarin ducks in the growing period
From 6 weeks to 18 weeks, ducks and ducks have a rapid growth period, high demand for nutrition, strong appetite and large appetite. The growth period is characterized by strong adaptability to the external environment and easy management.
2. 1 transition feed
3 ~ 5 days before the ducklings are transferred from the duckling house to the breeding house, the ducklings' feed is gradually changed into medium feed, so that the ducklings can gradually adapt to the new feed. Duck sheds are generally not heated, but the temperature difference between indoor and outdoor is large in winter, which will cause colds or other diseases, so the temperature should be raised appropriately a few days ago. You must be on an empty stomach before you transfer to another group.
2.2 Growth period feed
During this period, the consumption of coarse and green feed should be gradually increased, and green feed should account for 50% ~ 70% of concentrate. If there is no green feed, 0.0 1% poultry multivitamin should be added according to the total amount of ingredients. The formula of concentrate is as follows: corn 60%, bran 15%, fish meal 2%, bean cake 15%, bone meal 2%, hay meal 4%, salt 0.37%, choline chloride 0.03%, trace elements 0. 1% and methionine 0.03%.
2.3 management
2.3. 1 Keep the circle clean and dry, pay attention to wind and rain, and have a shade shed on the sports ground in summer.
2.3.2 The density is suitable, and the optimum density is 10 ~ 15 /m2. With the growth of duck age, it is necessary to constantly adjust the density to keep the air in the circle fresh.
2.3.3 Group feeding, according to the strength of the size, especially for weak middle-aged chicks with small weight and slow growth, strengthen management to make their growth and development catch up with strong ducks of the same age, and improve the uniformity of duck growth and development.
2.3.4 During the growing period, the duck house should be equipped with a bath pool, and the duck house should be bathed regularly every day, but the bathing time in the later period should not be too long, so as to avoid excessive energy consumption affecting economic benefits.
2.3.5 Putting a few small gravel boards in the pen or adding a certain proportion of sand particles in the concentrate will help improve the digestive function of ducks, reduce feed consumption and improve feed conversion rate.
3 Late fattening of ducks
Mandarin ducks and ducks began to concentrate on fattening two weeks before they were sold, and the ducks were moved to a dark and ventilated shed, and their activities were appropriately restricted. Feed them with high-energy feed or crushed corn kernels and let them eat freely. When most individuals are full of fat, they can be sold in time.
Prevention and treatment of duck diseases
4. 1 Formulate comprehensive preventive measures, regularly clean and disinfect pens and appliances, and keep pens clean, dry and hygienic. Foreigners are strictly forbidden to enter the duck house.
4.2 Do a good job in the prevention of cholera and duck plague. Inject 0.5ml/ inactivated avian cholera vaccine/bird at 60 ~ 70 days old, and inject inactivated duck plague vaccine1ml at 70 ~ 80 days old; In order to prevent white dysentery in newborn ducklings, 0.02% oxytetracycline or 0.0 1% furazolidone can be mixed for 3-5 days, or 0.0 1% potassium permanganate solution or 40,000 units/kg gentamicin water can be used to give ducks water.
