The black swan is native to Australia and is an important member of the swan family. It is a famous bird in the world. Physical characteristics of the body in addition to a small part of the primary flight feathers are white, the rest of the body feathery dark, back veiling like wedding plume, bright red, front with a "V"-shaped leucorrhea, iris red, black, weight 4 ~ 7 In kilograms, the neck often has an "S"-shaped curve, which is decent and beautiful. Its temperament is docile and easy to raise. It can breed two nests each year in spring and autumn in China. It can produce 4 to 5 nest eggs with an artificial stimulation of spawning, and the eggs can reach 30 eggs. The breeding method of black swan is simple and the disease resistance is strong. , is a labor-saving, highly effective breeding boutique.
First, the requirements of environmental conditions and feeding methods
1. It is advisable to avoid the outside interference as much as possible in the selection of large-environment conditional sites away from villages and living areas.
2. Naturally scattered black swan in the free-range situation, the water area can be large or small, generally 1 square geese can be stocked for every 100 square meters of water, planting some emergent plants in the pool, the pool perimeter can be used as seasonal rotation for pasture For their feeding, and planting some trees for shade in the summer, the surrounding of the free-range areas is surrounded by 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. When the black swan is in free-range conditions, it is required to manually break the wings or to manually cut feathers once a year to prevent flight. The method of shearing feathers is simple. The specific operation method is to cut out 5 to 6 primary feathers each year after changing feathers in autumn. can.
3. If cages are housed in cages, the housing area is 30 square meters, including a pool of 10 square meters. The depth of water is 60 centimeters per house.
Second, feed standards
1. Breeding goose feed is mainly composed of concentrated feed (used for laying hens pellets), supplemented by green feed (including pasture, vegetables, etc.). During the breeding period, 5% fishmeal and 3% shell powder are added to the concentrate to meet the breeding needs.
2. The feed for goslings requires that the daily diet be 70% of concentrated feed, 30% of green feed, and meat pellets with high protein content.
3. Young goose goslings are raised to 4 months of age to enter the young geese feeding stage. Concentrated feeds can be used to feed granules of egg chickens and green feeds can be fed freely.
Three pairs of breeding geese
1. Young geese begin to be paired during the 18 months of age into the breeding period, allowing them to freely fall in love in the free-range area. The paired swan-shaped swan is inseparable. In and out of doubles, you can think that pairing is successful and the formation of the pair is relatively stable. There is a phenomenon of two husbands.
2. Forced pairing: For swan that has not been paired successfully for free love, it can be solved by artificial force pairing method. The specific operation method is to place the unsworn black swan with a male and a female into the adjacent cage. , so that they are mutually unattainable, if the frequency of the two goose across the net together, nodding to show when you can put in cage feeding. If the pairing phenomenon occurs, it can be placed in a free-range breeding area. If it fails, it can be used once more. Usually, the problem can be solved once.
IV. Work during reproduction
1. Providing Nesting Black swan enters sexual maturity at 20 months of age. At this stage, it provides nesting materials such as dry thatched grass, ryegrass, and rice straw for its free collection to build nests.
2, the natural hatching black swan can be spawned after the nest is built. Generally, the first egg is produced between 8 and 15 days after the first mating, and after the next day, it can produce 6 to 7 pieces each day. If it is allowed to hatch naturally, It is necessary to build a small shed on the top of the nest to shelter from the rain and to eliminate human interference during hatching.
3, artificial hatching in the production of the first egg can be removed from the nest eggs, to replace it with a false egg, after the removal of new eggs, and finally remove the dummy eggs, take care when taking eggs to take protective measures to prevent the swan Attack, causing harm. Generally 20 days into the second spawning period, the second clutch can allow its natural hatching. Incubation storage for 4 to 5 days, when the number of large eggs can be used to hatch the machine, the amount of eggs can be hatched using simple methods of artificial hatching generally warm water is better. The Schwing's scheme is preferably incubating at a temperature of 38°C for 1 to 15 days, 37.5°C for 16 to 32 days, and 36.8°C for 33 to 35 days. Eggs are dried once every day for 25 days, each time for 5 to 8 minutes, 32 After days of artificial moistening, to increase the hatching rate of eggs, goslings hatched 35 days.
Fifth, brooding The natural hatching of the swan brood allows the geese to breed their own brood. The effect is ideal. The artificially hatched geese brooding should do the following:
1, the temperature shell 1 ~ 7 days for the 35 ~ 32 °C, after the weekly drop of 1 ~ 2 °C, gradually reduced to natural temperature, the temperature is appropriate or not as the goslings state of mind set.
2. The serum of gosling quail (0.5ml) was injected subcutaneously into the neck of the gosling within 24 hours after hatching.
3, feeding goslings 30 hours after the shell can be opened to drink, drinking water with warm water, drinking water, antibiotics for 3 days, 2 hours after the start of feeding to feed, feed daily feeding 6 to 7 times, free to drink.
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, sulfos and other preparations. Disinfect the drugs regularly. .
2. During the breeding period, broad-spectrum antibiotics such as amoxicillin, oxytetracycline, cyproterone, etc., or Chinese herbal medicine, may be used for feeding for three days every month to prevent poultry disease.
3. The breeding geese intramuscularly inject the gosling gizzard serum and goose paramyxovirus oil seedlings at the beginning of March every year.
VII. Prevention 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 mental status of the black swan. To achieve early detection, early isolation, early treatment, symptomatic medication to prevent the spread of poultry disease.
