Breeding technique of spotted-billed wild duck

The spotted-billed wild duck is similar to a green-headed duck in shape, weighs 890-1340 grams and is 560-632 mm long. it has similar male and female feather color, mostly dark brown feathers, obvious pale yellow eyebrow spots on the side of the head, black mouth peaks and tip yellow, which is different from other wild ducks; cheeks, whiskers, throat and front neck are all white; the wing mirror is metallic blue-green and flashing grayish purple.

Preparation condition

Hatchery, incubator, nursery (net enclosure 2 square meters), adult duck house (composed of duck shed sports ground swimming pool), duck breeding house.

Hatching details

1. Selection of breeding eggs: carefully selected, no split, no deterioration, no peculiar smell, thick shell put the big head up on the hatching egg rack.

2. Disinfection of breeding eggs: spray the breeding eggs directly with 1000 times permanganate solution, then put them in the incubator and close the door.

3. Incubation period management: hatching for 28 days, the temperature is set between 37.20-37.80 degrees Celsius and the humidity is between 42-65%.

4. Egg drying: from 5: 00 to 7: 00 in the morning and from 17:00 to 19: 00 in the evening, there are two times every two hours, to cool off the heat and breathe fresh air.

5. Turn eggs: turn eggs every two hours from the first day.

6, according to the egg: a total of 5 times, the 7th day according to the egg will see black dots, called beads, the 13th day can see the blood vessels, the 18th day to see the head, there is swallowing action, the 21st day can not see the bright area called closing the door, there is an oblique mouth.

7. Shell: the fully formed mouth begins to peck the shell on the 26th day, and the egg will be transferred to the shell machine after the 28th day. The temperature should be controlled at 38 degrees. In order to make it easy for the duck to come out of the shell and spray a layer of water on it to soften the eggshell, the duckling will come out of the shell completely after two days. After coming out of the shell, put the duckling in a bamboo frame covered with straw, and be sure to wet your feet before entering the nursery. Only let the duckling's feet into the water, do not wet the feathers. This is to let the duckling adapt to the living environment as soon as possible, and then it can be transferred to the brooding room.

The duckling can not drink water or eat food within 24 hours without affecting the survival rate. The best transportation distance is 24 hours. The temperature in the car is 25-30 degrees.

Brooding

Brooding takes 15 days, and the first 7 days are the most important.

1. Prepare before entering the chick: first, spray the whole brooding room with 1VR 1000 potassium permanganate solution, spray the straw you need, dry it and then spread it in each fence with a thickness of about 5 cm, and then put in the ducklings, about 25-30 ducklings per square meter.

2. Start eating: fill the sink with water and put it into the chick frame. The ducklings will be fed three hours after drinking water. Put the feed on the plastic film to let the ducklings find food freely, use the plastic film for three days, and feed the ducklings in the trough three days later.

3. Formal brooding: feed the ducklings 6 times a day every 2 hours after drinking water and feed the ducklings at the age of 3-7 days. After 30 minutes of feeding, the ducklings will take away the trough as much as drinking water six times a day, each time feeding 2% of the duckling's body weight during the day. (difficult to master) 60 are about 1-2 materials.

4. Vaccination: the duckling should be injected with duck hepatitis vaccine within two or three days after birth, injected from the back of the duckling's neck with a dose of 0.2ml (ML) per duckling. The bird flu vaccine was injected before and after 15 days. The duckling was injected with 0.2ml ML from the inner thigh of the duckling.

5, temperature control: when the temperature is between 25 and 30 degrees, do not do any treatment, when the temperature is between 22 and 25 degrees, cover the upper half of the fence with plastic film, when the temperature is between 20 and 22 degrees, completely cover the fence with plastic film. When the temperature is lower than 20 degrees, you need to use a carbon stove to heat up the temperature to 25 degrees as the medium line. When the temperature is higher than 30 degrees, you need to open the outer film of the greenhouse and cover it when it is lower than 25 degrees.

6. Test the water: 3-day-old ducklings need to test the water. The temperature is above 25 degrees to let the ducklings get into the water. Preferably at noon on a sunny day, the launching time should not be too long. They should not rush ashore in an hour or so. After landing, the hair is dry and then driven into the water. Two or three times a day. The duckling feathers won't get wet after three days.

7. Cleaning: clean every corner of the fence house every day, disinfect every three days, mix the glutaraldehyde sunflower ammonium formamide emulsion with water into 1500 times dilute solution for disinfection. Wash the utensils every two days and disinfect them with 1000 times potassium permanganate.

8. Duckling cold: runny nose, listlessness, no food, inability to move, always lying on the ground, the edge of the tongue is white, penicillin streptomycin can be injected into the muscle of the duck's inner thigh, the dose is 0.15 ml, once a day, it can be cured for three consecutive days.

Commercial duck (young wild duck)

Commercial ducks aged from 15 to 60 days old are completely fed in the form of stocking with a density of 6-8 ducklings per square meter. Ducklings can be managed by a group of 300 ducklings all day, and then rush back to the house to have a rest at night.

1. Disinfection: the barn is disinfected every three days, and the 2000 times dilute solution is sprayed in every corner of the barn with glutaraldehyde, sunflower and ammonium formamide emulsion mixed with water.

2. Feeding: feed more than 8 hours a day after 15 days. If there is enough food outside, feed three times a day. Put the feed on a plastic film to let the ducks look for food freely. Feed once every 4 hours for 30 minutes a day. The feeding amount is about 1.5% of the body weight of each duck.

Later rearing of commercial ducks

From the age of 60 days to the stage of leaving the building fence, the green material is mainly fed with green material and rice, and the green material is fed twice a day, and the weight of the green material is about 3% of the weight of each individual. (take 1000 ducks weighing 2 jin as an example, 60 jin is required.) the feeding time is 7-8 o'clock every day, 17-18:00, and the rice is fed at 16:00 every afternoon, with a feeding rate of 2% of each individual's body weight. (take 1000 ducks weighing 2 jin as an example, you need to invest 40 jin.) 120 jin, 60 jin, 7200 jin, 2400 jin.

1. Cleaning: clean up every day, clean up the barracks and playgrounds, and clean up all the feces.

2. Disinfection: disinfect the barracks and playgrounds and spray 1000 times permanganate solution directly every three days.

3. Exercise: drive it away many times to increase the amount of duck and keep the game.

4. Column: it can be sold at the age of 120 days.

Duck breeding management

Sexual maturity can be achieved at the age of 300-360 days. According to the male-to-female ratio of 4:1, the seed is reserved for the laying period from April to June every year, and other non-laying time is called the non-laying period. Full-price feed and ryegrass can be used in the non-laying period. The compound feed with calcium and phosphorus of 2:1 is 7: 00 in the morning and 13:00 at noon, each time is 4% of the total duck weight as the standard, and ryegrass is fed once a day. The time is 17:00 in the afternoon during the laying period, protein is added to the feed, 200g per 1000 grams as the standard.
