Watching the breeding technology of rare birds and black swan

The black swan is native to Australia and is an important member of the swan family. It is a famous ornamental bird in the world. In addition to the small part of the primary flight feathers, the body is full of feathers, and the others are feathery in color. The back is covered with a wedding flower plume, which is bright red. The front end has a V-shaped leucorrhea. The iris is red and black, and the body weight is 4-7 kilograms. S-curved, deportment dignified and beautiful. Its gentle temperament is easy to raise. In the spring and autumn of our country, we can breed two litters and use artificial stimulation of spawning to produce 4 to 5 litters. The number of eggs laid can reach 30. The black swan's feeding method is simple and its disease resistance is strong. It is a kind of labor saving. Efficient breeding products.

I. Environmental conditions

Feeding sites should be located far away from villages and living areas to avoid outside interference as much as possible.

1. Natural free-range: The water area of â€‹â€‹the black swan in free-range may be large or small. Generally, 1 pair of geese can be stocked per 100 square meters of water, and some emergent plants can be planted in the pool. The empty area can be used as the seasonal rotation for pasture. It feeds and arbors some trees for shade in summer. Surrounding the free-range area is a 1.5-meter-high mesh or fence to prevent other animals from entering the disturbance and affecting their growth and reproduction. The water in the pool should be regularly sterilized. Generally, 50 kg of fresh lime powder or 20 kg of bleaching powder should be sprinkled per mu of water surface. In the case of free-range breeding, the black swan must be artificially winged or sheared once a year to prevent flight. The method of shearing feathers is simple. The specific operation method is: After the black swan changes its feathers every autumn, it can cut 5 to 6 primary feathers.

2, cages and cages: the area of â€‹â€‹cages should be 30 square meters, containing 10 square meters of pool, water depth of 60 cm, each house raise l pairs of geese, pool water regularly replaced.

Second, feed standards

1. Breeding goose feed: mainly feed on refined feeds (granules available for laying hens), supplemented by green feed (including pasture, vegetables, etc.). In the breeding period, 5% fishmeal and 3% shell powder are added to the concentrate to meet the breeding needs.

2, goslings feed requirements: diet for 70% of concentrated feed, green feed 30%, concentrate feed with high protein content of meat pellets used for chicken material.

3. Young Geese: Goslings are raised to 4 months of age to enter the young geese feeding stage. Concentrated feed can be used for pellets used in laying hens, and green feed is provided for free feeding.

Three pairs of breeding geese

1. Young geese begin to pair up at 18 months of age to prepare for breeding, allowing them to freely fall in love in the free-range areas. The swan is relatively stable after being paired, and there is even a phenomenon of male and female parents.

2. Artificially forced pairing: For swan that has not been paired successfully for free love, artificial force pairing can be adopted. The specific method of operation is to place unmatched black swan males and females in cages in neighboring cages so that they are mutually unobtainable. If the two goose nets meet together and nod their heads to show their love, they can be kept in the same cage. . After the pairing phenomenon occurs, it can be put into a free-range breeding area. If it fails, it can be re-allocated once. Usually, the problem can be solved once.

IV. Management during breeding period

1. Provide nest materials: The black swan enters sexual maturity at the age of 20 months. At this stage, nesting materials such as dry thatched grass, ryegrass, straw, etc. are provided around the area for its free use to build nests.

2. Natural hatching: The black swan can lay eggs after it builds a nest. Generally, the first egg is produced 8 to 15 days after the first mating, and the next one is born every other day. Each nest can produce 6 to 7 pieces, let it be natural. For hatching, a small shed is to be constructed on the top of the nest to shelter from the rain and to prevent human interference during hatching.

3, artificial hatching: in the production of the first egg can be removed from the nest to replace it with a false egg, after only take the new production of eggs, and finally remove the false eggs, when taking eggs manually to take protective measures to prevent Attacked by a swan, causing damage. Generally 20 days into the second spawning period, the second clutch can allow its natural hatching. Eggs can be stored for 4 to 5 days, the number of eggs can be used for a long time to hatch the machine, eggs can be used when a small amount of artificial incubation method, generally warm water hatching is better. The Schwenn program prefers variable temperature incubation, with 1 to 15 days at 38Â°C, 16 to 32 days at 37.5Â°C, and 33 to 35 days at 36.8Â°C. Eggs are stored once every 5 to 8 minutes after 25 days of incubation, 32 After days of artificial moistening, to increase the hatching rate of eggs, goslings hatched 35 days.

Fifth, brooding

Naturally hatched swan broods can allow breeding geese to bring their own, so the effect is ideal. The hatching gosling brooding should do the following:

1. Temperature: 35Â°Cï½ž32Â°C for 1~7 days from the shell, then drop 1Â°Cï½ž2Â°C every week, and gradually reduce to natural temperature. The temperature is appropriate or not depending on the mental state of goslings.

2. Epidemic prevention: Goose quail serum 0.5 ml was injected subcutaneously into the neck within 24 hours after hatching. ?

3. Feeding: The goslings can be opened 30 hours after hatching, drinking water with warm water, drinking water with antibiotics for 3 days, feeding 2 hours after feeding, and feeding 6 to 7 times a day, free for drinking.

Sixth, health and epidemic prevention measures
?
1. Clean up the sanitation regularly in the breeding area, keep it clean in the breeding area, and use a disinfectant liquid to spray and disinfect to kill various pathogens. Commonly used disinfectants include quaternary ammonium salts and iodine-containing preparations. Regularly replace disinfectant drugs. .

2. During the breeding period, broad-spectrum antibiotics such as amoxicillin, oxytetracycline, cyproterone, etc. or Chinese herbal medicine can be used for feeding for three days every month to prevent the occurrence of poultry diseases.

3. The breeding geese intramuscularly inject the gosling gizzard serum and goose paramyxovirus oil seedlings at the beginning of March every year.

VII. Prevention and treatment of common diseases

The main diseases of the black swan are gosling plague, E.coli disease, goose paramyxovirus disease, fowl cholera, and parasitic diseases. While doing regular work, we must regularly observe the black swan's mental state. Early bird disease detection, early isolation, early treatment, symptomatic medication to prevent spread.
