Shaoxing duck breeding and management technology

Light: Natural light during the day and artificial light at night. One-week-old ducklings were lighted for 24 hours, with a light intensity of 5 watts per square meter and a light bulb 2 meters above ground. The gradual transition from 2-4 weeks of age to the use of only natural light, the light intensity is gradually reduced to 1 watt bulb per square meter.

Miao duck selection: General selection of eye suddenly God, claw luster, lively and joyful ducklings. Spring ducks hatch from April to April, start production in July-August, and stop eggs after winter; summer ducks hatch in May-June, open production in September-October, and stop eggs in Meiji in the following year; autumn duck 7- It hatched in August and opened in December to January.

Open drink to eat: Ducks drink water for the first time, and drink for the first time. They usually start by eating and then start eating. Two-thirds of the ducklings in the ducklings can eat when they have foraging behavior. They are usually washed with wet pellets or raw rice water and sprinkled on plastic sheets. Open the drink half an hour before eating, by placing the ducklings in a bamboo basket and slowly immersing them in a water bowl at a water temperature of 15°C or more. Let the water soak the toes and stay in the water for 5-10 minutes so that the ducks can drink water. May not wet duck feathers.

Feeding amount: Within 10 days of age, 4 times during the day and 2 times during the night, the amount of feed should be appropriately controlled in the first 3 days, eat 70% to 80%, and the feed should be released from the 4th day, but you shouldn't be full, each time Feed for 10-15 minutes. At the age of 11-20 days, 4 times during the day and 1 at night, the feeding amount was calculated as 100 ducklings, 250 grams on the first day, and 250 grams per day thereafter. 5 kg (ie, 125 grams per duck per day).

Drainage training: ducklings, commonly known as water release, should start training as early as possible to improve the duck's ability to adapt to the environment. Within 1 week of age, ducklings are usually closed in bamboo shoots in summer and autumn and immersed in water for 2-3 minutes. In winter and spring season, ducklings can be placed in shallow water basins. The depth of water is about 2 centimeters, and water depth is gradually increased. , And move the basin from the indoor to the outdoor, after a few days, the ducklings will get used to the water. Draining was performed 15 minutes after feeding. After 1 week old ducklings, if the weather is fine, the water can be discharged directly into the river. Each time the water is released, it starts at 20-30 minutes and then slowly extends to 1 hour. After going into the water, ducklings should be allowed to sit in the sun or where there is no wind and warm. After the wet hair on the body is dry, it can be rested in the brooding room.

Feeding in groups: The rearing of ducklings is an important part of improving the survival rate. Generally, 100-200 birds per group are appropriate. Before the ducklings start to drink, they should be reared separately according to the sooner or later and the strength of the hatchlings. The weak chicks should be given priority care; after 3 days of eating, they should be grouped again, checked by feathers, and the small and young ducklings should be kept together. Increase the number of feedings and the ambient temperature appropriately.

Weight control: Overweight of young ducks can lead to premature birth. Generally, measures such as strengthening exercises and controlling the amount of material can be used to prevent ducks from becoming overweight.

Breeding density: 8-10 feathers per square meter. If the ducklings are placed in the house and reared directly, the density is calculated as the breeding density of ducks, that is, 6-8 feathers per square meter.

Illumination: Natural lighting is used. For ease of management and ducks drinking at night, to prevent rat damage, etc., the house can be illuminated with weak lighting (0.3-0.5 watt bulb per square meter).

Early egg production: The initial stage of egg production refers to the period before the start of production until the egg production rate reaches 60%, which is generally between 120 days and 160 days. This period should be based on the increase in egg production, improve feed quality, increase dietary nutrient concentration and feeding times, feeding 3 times during the day, and feeding once during the night at 9-10. Each duck feeds an average of 150 grams of feed each day. about. Illumination time increased by 15-20 minutes a day, reaching 16-17 hours by 22 weeks of age.

Mid-production: The mid-production period refers to the period from 60% egg production to the end of egg production peak (the egg production rate drops from peak to below 80%). The nutrient concentration of the feed during this period is higher than that of the previous stage. Especially during the peak period of egg production, crude protein should be up to 20%, and the amount of calcium should be increased accordingly. The appropriate ratio of calcium and phosphorus should be maintained, and a certain amount of egg poultry should be supplemented. With a variety of vitamins, appropriate amount of green feed.

Late egg production: If properly reared, the egg production rate of Shaoxing ducks can still reach about 80% at 450 days, and the egg production rate at 500 days is reduced to about 75%. When the egg production rate is reduced to 80%, the rearing and management of the laying season should be implemented. The main point is to reduce the rate of egg production decline in the duck group as much as possible.

When the egg production rate is below 60%, the ducks will be eliminated in time, and moulting may also be forced manually to advance the laying duck to the second laying period. Compulsory moulting practices are as follows: (1) Strong disturbance, intended to drive ducks in duck houses, intentionally disturbing stimulating ducks during driving; (2) Reduce lighting, properly block windows during the day, and not turn on lights at night; (3) Reduce feeding The number of feedings is two times on the first day and one on the second day. The third day begins with a 2-3 day break before starting and feeding. When the material is cut off, the supply of drinking water must be guaranteed, that is, continuous water must be cut off. Through the above method, about 10 days later, you can try to remove the main wing feathers. If the feather roots are dry and easy to pull, you can start pulling the feathers manually, pull out the main wing feathers, and then pull out the aileron and tail feathers. About 1.5 months after the general plucking, the new feathers are long and the ducks begin to lay eggs and enter the second laying period.

In order for the ducks to develop a set of management habits from a young age, the daily feeding and management procedures are as follows: in the morning (5-8 o'clock, winter may postpone some), put the ducks out of the water to the surface activities, pick ducks into the ducks, pick eggs, The feed bowls and bowls were washed and placed on a sports ground, mixed with feed, and fed for the first time; in the morning (8-11 a.m.), the grass was cut and sprinkled on the surface of the water for feeding by ducks. After the basin is cleaned, it is moved into the house, filled with fresh water and feed for the second time. The duck is fed to collect the eggs produced by the duck on the playground; at noon (11:30-13:30), the duck is released. Sow the grass on the surface of the water, put the pots and basins inside the house and put it on the playground after cleaning; in the afternoon (15:00-16:30), put the feed and clean water into the material basin and the water basin, the third time. Feeding, the duck house is paved with hay, and then the material basin and the water basin are moved into the duck house, feeds and clear water are added at night, and the duck is fed into the house and turned on.

Galacto-oligosaccharides are made up of plant sugars linked in chains. They are found naturally in dairy products, beans, and certain root vegetables. People use galacto-oligosaccharides as prebiotics. Prebiotics act as food for "good" bacteria in the intestine. Don't confuse prebiotics with probiotics such as lactobacillus, bifidobacteria, and saccharomyces, which are live organisms that are good for health.
