How many species of black dolphin are there, and they all breed it in large quantities there.

Black dolphin is a small animal, each cage can breed 3-4, and the reproduction is very fast, take 100 as an example, the introduction of 100 seedlings, one or two months later can be reproduced to 300-400. The cost of breeding mainly includes the breeding house, feeding equipment, back to the cavity feed cost, as well as water and electricity medical expenses, now the seedling of the first in 25 yuan a, the breeding house and feeding equipment within 5000, the black dolphin eats less, a black dolphin rebirth to the slaughter feed fee is only a few dollars, so to breed 100 black dolphins as an example, the breeding cost is about 10000-12000 yuan. Breeding profit a black dolphin only needs 3-4 months to slaughter, generally weighing between 1-2 pounds, small size, but not cheap, a black dolphin leakage shirt between 20-35 yuan.

Start to introduce 100, you can breed 1,500 in a year, remove the seedlings, the first year can be ** thousands of commercial black dolphins, can earn 30,000-50,000, in addition to the cost of breeding, you can get a net profit of about 20,000. In addition to the sale of meat porpoises, you can also choose to be in good spirits and clever for pet sales, and you can also specialize in breeding dolphin laughing wax, so that the profits will be higher.

(Based on the analysis and calculation of the benefits of 10,000 yuan in the introduction and development of black dolphin breeding).

1. Expenditure: 1) Expenditure on building a dolphin house:

It needs 120 square meters, and the cost per square meter is 90 yuan, 120 * 90 yuan = 10,800 yuan (2) feeding pool expenditure:

66 breeding pools * 12 yuan = 792 yuan; 60 fattening ponds * 12 yuan = 720 yuan, a total of 1512 yuan.

3) Dolphin Breeding Expenditure:

110 male dolphins * 10 yuan = 1100 yuan, 220 female dolphins * 40 yuan = 8800 yuan, a total of 9900 yuan.

4) Expenditure on feed and medicine:

330 breeding dolphins * yuan * 365 days = 8431 yuan.

Dolphins 220 * 15 * 120 days * yuan = 23,760 yuan (5) water and electricity bills: 300 yuan per year.

6) Feeding utensils: 500 yuan.

7) Forage planting: 1500 yuan.

8) Total expenditure: 56,403 yuan.

2. Income (calculated on the basis of commercial dolphin sales).

220 female dolphins can reproduce more than 3,300 dolphins in circulation every year, all of which are commercially fattened and raised, and the average size of each commercial dolphin is calculated in catties.

3300 * Jin * 15 yuan Jin = 68250 yuan.

3. Net income: 64,350 yuan - 56,403 yuan = 7,947 yuan According to the above calculation, the investment cost can be basically recovered in the first year and achieve profitability, and the benefits in the second year are more considerable.

The female black dolphin does not bring her own cubs, and the newborn cubs should be trampled to death without the protection of the mother mouse, why is this? How can we prevent this?

Black dolphin farming? If you haven't already, don't raise it. In addition to speculating seeds, you can't make a lot of money.

The market has to find its own. The pet market is not as good as the dolphins, and the food market is not as good as the meat rabbits. It is not as good as the local breed of meat rabbits (such as Chinese white rabbits and Lianshan black rabbits).

-,-Guinea pigs like the dark, not the sun...

Baby guinea pigs from birth to 20 days basically do not need to be fed, from 20-35 days an average of 100 grams of grass and 2 cents of feed per day, from 36-60 days of slaughter an average of 200 grams of grass and 3 cents of feed, 60 days of total consumption of grass about kilograms, according to the yuan of the kilogram of ** yuan, feed expenses of about yuan, each subsidy breeding dolphin breeding expenses yuan, wages and other expenses, comprehensive total feeding costs for yuan, even if the feeding time is 100 days, the weight of 600 grams, The cost is also below the yuan, and each weighs 500-800 grams. Even if it is calculated according to 10 yuan and 500 grams, the profit is more than 5 yuan, if it is calculated according to the lowest price of 15 yuan and 500 grams in the current market, the profit is 10 15 yuan per piece.

Compared with breeding chickens: a chicken seedling needs about 2 yuan, drugs and vaccines need about yuan, feed needs about 8 yuan, and the profit of each chicken is only 1 yuan ......

Compared with breeding ducks: a duck seedling needs about 1 yuan, drugs and vaccines need about 1 yuan, feed is about 8 yuan, and the profit of each duck is only 1 2 yuan ......

Compared with breeding geese: a goose seedling needs about 12 yuan, drugs and vaccines need about 2 yuan, feed is about 16 yuan, and the profit of each goose is only 5 8 yuan ......

The economic benefits of breeding black porpoise are 10-30 times that of breeding chickens, ducks and geese, and the technical difficulty of breeding is only one-fifth of that of breeding chickens, ducks and geese, and the taste of black pork meat is better than them.

Black dolphin breeding is still in management, the key is that if there is frost in winter, it is very important to keep the place warm, and the room temperature is below 12 degrees Celsius It is easy to die. So consider it locally. The investment cost is really not high, and the reproductive ability is also very strong. What to consider is the temperature, and the sales.

A hundred pairs of black dolphins can't turn any money at all.

1. Black dolphin breeding generally adopts cage breeding, pond captivity, three-dimensional scale factory farming, etc., so the facilities should be suitable according to the breeding method. If the cage is generally suitable for a small amount of breeding, the cage can be made of wood, bamboo, and wire, and the scale is 60 cm, 50 cm, and 40 cm; Pond captivity is suitable for bungalows, wide house use, the room with bricks, planks and other square meters of the pool, the pool is best to pad some sawdust or hay; The three-dimensional factory farming is suitable for large-scale, pretending to sell the number of centralized management of farming, generally can be made of bricks or wood, iron bars into 3-5 layers, pools, cages with small doors, etc.

2. The diet of the black dolphin is very mixed, and its normal growth and development usually require sufficient nutrient supply. Generally, in the breeding process of black porpoise, concentrate and green fodder can be supplied as its main feed. Among them, corn flour, wheat bran, rice bran and other concentrates are the main concentrates, while green materials are mainly oak grass, corn leaves, sugarcane leaves, leaves, carrots, etc.

3. The breeding management of black porpoise focuses on preventing mold and deterioration of feed. Compound feed is best to be fed with matching, pellet feed directly fed, should put clean water for drinking, or mixed feed feeding, eat less and eat more meals. At the same time, clean up the feces every day, and brush the utensils frequently, so as to keep the trough clean and hygienic.

In addition, the black dolphin is easily frightened, the breeding room should be kept quiet, the room temperature is best kept at 18-25, the relative humidity is 45-55%, and the winter is warm. Finally, it is necessary to do a good job in the prevention of natural enemies such as rodents and snakes.

4. After preliminary observation, the female is born about 45 days ago, and the male has sexual characteristics about 70 days old, but the initial mating period of the female should be after 70 days to ensure the reproductive rate.

1. Black dolphin breeding prospect 1, black dolphin meat is delicate, delicious and noisy, belongs to low-fat, low-cholesterol meat, market demand is large, the market is good.

2. Black porpoise has few diseases, simple breeding, high efficiency, low breeding cost, and broad breeding prospects.

Second, the cost of breeding and profit analysis 1, the cost of breeding: including the construction of the farm, breeding cages and breeding equipment, seedlings, feed, water and electricity, drugs and labor and other costs, the total cost of breeding is about 10,000.

2. Breeding profit: breeding 100 black porpoises, the profit is about 60,000, and the net profit minus the cost is about 40,000.

3. Advantages of black dolphin breeding 1. Black dolphin is a kind of filial piety wild animal that is allowed to be bred by the state and the market is relatively open, and the circulation in the market is relatively smooth.

2. Black pork meat is of good quality, green, healthy and nutritious, and has a large market demand.

3. Black porpoise is easy to breed, has a high survival rate, low breeding cost, short growth cycle and high economic benefits.

As of June 16, 2020, the black dolphin is a wild economic animal allowed to be farmed by the state and the market is open, and the market can circulate smoothly.

There are a variety of black dolphin breeding methods, according to local conditions, and the methods commonly used are: cage breeding, pond captivity, and three-dimensional scale factory farming. The cost of raising black porpoise is low, the technical difficulty is not large, the cost of feeding is only one-sixth of the civet, the technical difficulty is one-tenth of the civet, and the comprehensive cost of breeding a commercial black porpoise weighing 500-800 grams is only about 4 yuan.

The black dolphin is mainly herbivorous and is a typical small domestic animal that saves grain. The vast number of rural grassy hills and grassy slopes, feed resources are very rich, breeding black porpoise can effectively use the local grass feed, especially planting high-yield forage grass breeding black porpoise, in a very short period of time so that each farmer can obtain greater economic benefits, and can form large-scale breeding.

The state allows guinea pigs to be raised, why our boss, don't come to the door, **guinea pigs.

So what should we do, don't let you raise it.
