The method of breeding black dolphin

Black guinea pig, also known as Dutch pig and Dutch mouse, is called black dolphin because it is black. It is native to Peru in South America. It is a mammalian herbivore with delicate meat, delicious taste and rich in various trace elements. It is a delicacy on the dining table.

The method of breeding black dolphin

Black guinea pigs mature early, generally female dolphins are 35-45 days old, male dolphins have sexual characteristics at 70 days old, but female dolphins had better rebreed after 70 days old.

Gender identification presses the perineum with the hand to see if there is a penis and the shape of the vulva, then the male and female can be confirmed. During capture and inspection, hold the back of the black guinea pig with your right hand, hold its left shoulder with your thumb, and hold its right shoulder and chest with the other 4 fingers, so as to hold it gently and hold its body with your left hand.

The breeding dolphin should choose plump body, stout bones, positive limb shape, bright eyes, good nutritional status, bright coat color, soft and elastic skin, symmetrical testes of male dolphins and normal development of female vulva.

The oestrus duration of mating black guinea pigs is 1-18 hours, with an average of 9 hours. most of the oestrus time is between 5: 00 p.m. and 5: 00 a.m. after mating, there is a gelatin-like mixture at the vaginal orifice after mating. We can judge whether the black guinea pig is successful or not. In general, black guinea pigs reserved for original breeding adopt the mating method of one male and one female, that is, only one pair of breeding dolphins are placed in each culture pond, and the female dolphins should be allowed to live together and breed after the cubs are weaned. Male dolphins can be put in for blood matching within half a day after the female dolphins give birth. The mating rate and reproduction rate are high. When raising in large groups, 3-4 female dolphins are often put into 1 male black guinea pig for mating. Do not put 2 male dolphins in order to prevent fighting and affect breeding.

The sexual cycle of reproductive female dolphins is 16 days, and the duration of estrus is 1-18 hours, with an average of 9 hours. The gestation period of female dolphins is 56-68 days, the number of pregnant dolphins is 3-5, and as many as 6-9. The young dolphins are weaned after 15 days and fed separately after weaning. Usually, commercial mice can be reared for 60-80 days. During pregnancy, in addition to improving the quantity and quality of feed, the site should be kept quiet and clean, and idle personnel should not go in and out at will. Keep the diet fresh and feed less and eat more. In the third trimester, hay should be placed in the cage so that the mother dolphin nests ready to give birth. The lactation period of young black guinea pigs is 15 days in summer and 20 days in winter. The feed nutrition of female dolphins should be increased during lactation. Black guinea pigs have high reproduction rate and strong immunity, and the breeding life of dolphins is 3 years. There is no need for immunization and drug control in the process of feeding.

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.

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.
