The prospect of culture of white mackerel

Baiji is a national second-class key maintenance animal, which is not only a famous ornamental rare bird, but also has high medicinal value. Large-scale aquaculture farms need a lot of procedures, need to be put on record with relevant departments, and need special technical personnel. In terms of market price, the white mackerel of small seedlings costs 100 yuan and 150 yuan, and the adult one costs 500 yuan and 1000 yuan, which is highly adaptable and can be raised all over the country, so the prospect of breeding white mackerel is very broad.

Morphological characteristics of Euphorbia pulcherrima

1. Male bird: the crown on the head and the lower body are blue and black, the face is bare, red, the upper body and wings are white, from the back of the neck or back is densely covered with black lines similar to the "V" shape, the head has a long and thick black crown shaped like hair, and draped behind the head, the face is naked and bright red, the whole lower body is jet black, the long tail feathers of the upper body and the back of the body are covered with fine "V" shaped black lines on the white substrate. What is particularly chic is that the black lines on the tail feathers are getting smaller and smaller and disappear gradually.

2. Female: the upper body of the female is brown or olive brown, the crown is brown, the apex is dark brown, and the naked part of the face is small and crimson. The dorsal feather is lighter, the edge is deeper, the flying feather is brown, the secondary feather is decorated with black spots, the central tail feather is brown, the outer tail feather is dark brown, and it is covered with white wavy spots. The lower body is also brown or olive brown, with black beetle-like spots after the chest, and black-brown white spots under the tail.

The living habits of Baili

1. Gregarious: a small group of white birds in pairs or in groups of 3 to 6, sometimes as many as 16 or 17 individuals in winter. It consists of a strong male and several adult females, less strong or younger males and young birds, and there is a strict hierarchical relationship within the group. There is always a fierce struggle before the spring breeding season.

2. Eating habits: Baiji is omnivorous, which mainly feeds on young leaves, buds, flowers, stems, berries, seeds, roots and moss of vertebral chestnut, raspberry, passion fruit and other plants. The most common food is the nuts, cliff beans, fern leaves, banana taro and other plants of Castanea henryi. Also eat golden needle insects, locusts, ants, earthworms, Lepidoptera insects and larvae, beetles, ants, snails and other animal food.

3. Reproduction: during the breeding period from April to May, the eggs lay 480 eggs per litter, the eggs are light brown and covered with white calcareous spots, usually lay 1 egg every other day, and the eggs begin to hatch immediately after laying, and the incubation period is 24-25 days. The chicks are precocious and can leave the nest to follow their parents on the day they hatch.

Culture characteristics of White Carp

1. Adaptability: Baiji can adapt to all kinds of harsh climatic environment, artificial domestication and cultivation has gradually made it lose its wild wild nature, and has a strong ability to adapt to the flat environment of the net house.

2. Omnivorous: Baiji has a wide range of feed sources. It can feed on plant leaves, roots, stems, fruits and cereals, legumes, as well as insect larvae and eggs. The average daily intake is 75 grams, which can grow to 1-1.3 kilograms in May.

3. Fecundity: White mackerel lays eggs once a year, laying eggs in March, laying 216 eggs each time. The incubation period is 26 days. Under the ratio of 1 ∶ 5 (that is, 1 male and 5 female), the fertilization rate of breeding eggs can reach 87%, and the hatching rate can reach more than 80%.

4. Disease resistance: as long as the environmental hygiene of feeding is maintained, the disease of Baiji is very rare.

5. Easy to raise: the white mackerel cultivated by artificial culture has lost the ability to fly, so there is no need to worry about its flight escape, as long as it is in a flat farm with ventilation.

The hatching technology of Baiji

1. Natural hatching: in the cage, the female white mackerel nests or uses artificial nests to lay eggs and hatch. During the incubation period, you should keep the surrounding environment quiet. If you are frightened or attacked by the enemy, it will affect the hatching of the mother. At this time, the public will make a loud cry to lead the enemy to yourself and protect the mother.

2. Artificial incubation: it can be hatched by automatic incubator. Eggs should be screened and disinfected before hatching. The incubation temperature is 37.5-38.2 ℃ and the relative humidity is 55-65%. Turn the eggs every 2 hours at an angle of 90. Cold eggs are needed after 18-19 days of incubation, 2 times a day, 5-10 minutes each time, and the eyelids should be tested to feel slightly cool. Drop the plate 2 days before hatching, stop turning the eggs, move the embryonic eggs out of the chick and wait for the chicks to emerge.

The brooding technique of Baiji

The main results are as follows: 1. Temperature: the chicks are moved out of their shells and raised in groups in the brood, with 20 as a group and raised in small groups. Using infrared lamp as heat source, the initial temperature was 34 ~ 36 ℃, then decreased gradually with the increase of age, the temperature decreased to 28 ~ 30 ℃ at 30 days old and 22 ~ 24 ℃ at 60 days old, and then kept at normal temperature.

2. Light: light can promote growth, stimulate and enhance gonadal development, and achieve sexual maturity ahead of time. The chicks were exposed to light for 24 hours at the age of 14 and 12 hours at the age of 15 and 60.

3. Humidity: the suitable relative humidity of the baby is 50-55%. While ensuring the temperature, the air in the house should be properly ventilated to keep the air fresh, but the thief wind should be avoided and the cold should be prevented.

4. Feeding: the chick weighs 27,28g after coming out of the shell, drink 5% glucose water 24 hours after coming out of the shell (before eating), drink water for 1 hour and start eating, it is best to eat with bread worms first, and then feed with medium well's corn flour mixed with cooked egg yolk. After 5 days, it can be fed with full-price feed, which can be eaten freely, and small pellet feed is suitable for feed. Chicks are easy to suffer from B vitamin deficiency. B vitamins can be added according to 50 mg / kg in feed, and some cod liver oil, vitamin D, calcium and manganese can also be added to prevent leg bending disease. Green feed should be washed and cut into thin shreds for feeding.

5. Management: the brooding density can directly affect the survival rate, so a partition should be set up in the brooding box, which should be divided into several small rooms, and then raised in groups according to the size, strength and strength of the chicks, especially the chicks that are easy to fight and like to peck. To avoid pecking, disinfect the injured chicks with 0.01% potassium permanganate solution in time, then apply purple solution or sprinkle Yunnan white powder and raise them separately. When you are about 1 month old, you should cut off your beak and wings.

Culture techniques of White Carp

1. Farm construction: the shack for raising pheasant should be chosen in a quiet, dry, ventilated, well-drained place facing south. The cage house is divided into an inner room and a sports ground, the inner room is 812 square meters, the sports ground adopts cage net structure, which is 2025 square meters, and the purse seine had better use nylon net to reduce impact.

2. The preparation of diets: at present, there is no feeding standard for rare birds such as white oysters in China. In the process of feeding, the diets of white birds are prepared with different nutritional needs at different stages of their growth and development, with reference to the diets of other rare birds to achieve comprehensive nutrition, such as corn, soybean, wheat, etc., and then properly add cooked egg yolk, bread worms and some green feed.

3. Breeding during the breeding period: according to the different time of sexual maturity, the species should choose a good mate and group properly. The number of male white fish in the same group should not be too large, and 2-3 should be suitable. In order to prevent the occurrence of struggle, you can put a blindfold on the species of pewter to stabilize the group as soon as possible so that they can breed and lay eggs. Provide nest boxes for laying eggs in advance to pick up eggs in time to prevent breeding eggs from being pecked or stolen. During reproduction, it is necessary to increase the content of protein and calcium in the diet to prevent the production of soft-shell eggs.

4. Feeding in non-breeding period: the temperature decreases gradually in autumn, at this time, nutritious feed should be provided to the herd, and all kinds of vaccination and deworming in vivo and in vitro should be done well. Autumn is the best time for selling and selecting species of pewter. Cold protection, heat preservation and ventilation should be done well in winter, and ventilation should be left in the closed house.
