How to choose the site for raising black dolphins

There are a variety of breeding methods, according to local conditions, the commonly used methods are: cage culture, flat pond type captive culture, three-dimensional scale factory breeding. Breeders can choose their own breeding model according to their own conditions. Some aquaculture models require high investment costs, but high returns.

How to choose the site for raising black dolphins

This kind of feeding method can be adopted where a small amount of cage is raised, and its advantage is that it can control reproduction, feed, and keep clean and hygienic. The cage can be made of wood strips, bamboo slices and iron wire, and the specification is 60 cm × 50 cm × 40 cm.

Flat pond type captive breeding is suitable for bungalows and wide houses. The room is divided into a 0.5-1 square meter pool with bricks and planks, and some sawdust or straw had better be padded in the pool, which is conducive to keeping warm and absorbing moisture. At present, farmers often use this method to raise them.

Three-dimensional factory feeding is large in scale, relatively centralized, easy to manage and operate, and has a large number of breeding. Use brick or wood, iron bar to make 3-5 layers, the bottom is slightly inclined, so that feces flow out, easy to manage. There are small doors in the pool and cage. Generally according to the size of the cage to determine the number of stocking, per square meter density of 8-10 small, large 10-20. Generally speaking, the length and width of 100 cm × 50 cm can be put 1 male and 4 female, those of 80 cm × 50 cm can be put 1 male and 3 female, those of 60 cm × 50 cm can be put 1 male and 2 female, and those of 45 cm × 35 cm can be put 1 male and 1 female. And pond culture, box culture should be appropriate sparse.

Before raising black guinea pigs, the houses were sprayed and disinfected with 0.02% potassium permanganate solution. Black guinea pigs love to be clean, whether in captivity or cage, we should do a good job in the environmental hygiene of the breeding room, wash the trough regularly to prevent food mildew, ensure the freshness of feed and drinking water, and put an end to the pollution of feed and drinking water by wild rats and cockroaches.

The living habits of the black dolphin

Black dolphin, native to the mountain area of Yunnan, China, belongs to mammalian rodents. It has moderate body shape (0.75-1.25 kg), short limbs, blunt round head, large snout, short eyes and ears, long claws, and is characterized by black hair, black eyes, black ears, black feet, no tail, poor jumping, and generally does not bite or scratch people. The black dolphin is gentle, gregarious, sharp in hearing, timid and afraid of interference. Black dolphins make different sounds under different conditions. For example, when female dolphins are in estrus, male dolphins send out "Gollum, Gollum" love songs, and when they are hungry, they will scream when they hear footsteps.

The breeding method of black dolphin

1. Feeding equipment: black dolphins are raised in a variety of ways, taking measures according to local conditions, and the commonly adopted methods are cage breeding, flat pool captive breeding and three-dimensional factory breeding.

① captive. Where a small amount of feeding can be used in this way. The utility model has the advantages of being able to control reproduction, feeding, and keeping clean and hygienic. The cage can be made of wood strips, bamboo chips or iron wire with a specification of 60 cm × 50 cm × 40 cm.

② flat pool captivity. It is suitable to be used in the case of bungalow and width. The room is divided into a pool of 0.5-1 square meters with bricks and boards, with a height of 0.35 meters. It is best to pad some sawdust or hay in the pool, which is conducive to keeping warm and absorbing moisture. At present, most of them are raised in this method.

③ three-dimensional factory feeding. Its scale is large, relatively centralized, easy to manage and operate, and a large number of animals are raised. Use brick or wood, iron bar to make 3-5 layers, the bottom is slightly inclined, so that feces flow out, easy to manage. There are small doors in the pool and cage. All kinds of feeding methods generally have a small density of 8-10 per square meter and a large density of 10-20.

2. Feed supply: the feeding habits of black dolphins are very miscellaneous, and adequate nutrition is needed for normal growth, development and reproduction. As the black dolphin is a herbivore, the digestibility of crude fiber is high, such as long-term supply of green material or hay and other plants, the peeling phenomenon will occur, so the feed supply should be based on green feed, green feed and concentrate should be matched properly. Green materials with fresh and tender weeds, forages, corn leaves, sugarcane leaves, green vegetables, pericarp, carrots, sweet potatoes and so on. The concentrate is mainly corn meal, wheat bran, rice bran, etc., and the commonly used feed formula is 40% corn meal, 10% rice meal, 29% wheat husk, 15% peanut shell meal, 2% fish meal, 2% bone meal, 1% salt and 1% auxin. You can also feed piglets.

Preparation of black dolphin breeding ground

First of all, there are a variety of ways of raising black dolphins in breeding facilities, which are generally adopted in accordance with local conditions: cage breeding, flat pond type captive breeding, three-dimensional scale factory breeding.

1. Caged. Where a small amount of feeding can be used in this way. The utility model has the advantages of being able to control reproduction, feeding, and keeping clean and hygienic. The cage can be made of wood strips, bamboo slices and iron wire, and the specification is 60 cm × 50 cm × 40 cm.

2. Flat pond type captive breeding. It is suitable to be used in the case of bungalow and width. The room is divided into a 0.5-1 square meter pool with bricks and planks, and it is best to pad some sawdust or dry strokes in the pool, which is conducive to keeping warm and absorbing moisture. At present, most of them are raised in this method.

3. Three-dimensional factory feeding. Its scale is large, relatively centralized, easy to manage and operate, and a large number of animals are raised. Use brick or wood, iron bar to make 3-5 layers, the bottom is slightly inclined, so that feces flow out, easy to manage. There are small doors in the pool and cage. Generally, the stocking quantity is determined according to the size of the cage, with a density of 8-10 and 10-20 per square meter. Generally speaking, the length and width of 100 cm × 50 cm can be put 1 male and 4 female, those of 80 cm × 50 cm can be put 1 male and 3 female, those of 60 cm × 50 cm can be put 1 male and 2 female, and those of 45 cm × 35 cm can be put 1 male and 1 female. And pond culture, box culture should be appropriate sparse. Before releasing the black dolphin, spray and disinfect the house with a concentration of 0.02% potassium permanganate solution.

There are many ways to raise black dolphins, and breeders can choose their own breeding methods, but before raising black dolphins, the construction of a farm is essential, and the farm can be based on the principle of simplicity and convenience according to its own needs. try to save unnecessary costs.
