Black Dolphin Efficient Breeding Technology Black porpoise is a rare herbivore that combines game, food and medicine, and nourishment. Its delicious meat, good taste, no smell, is a high protein, high calcium, low fat, low cholesterol Green health meat food contains melanin which has the function of removing free radicals, improving immunity, and delaying aging. It contains three times as much iron as the soft-shelled turtle, and it is also rich in anti-cancer elements “zinc†and “seleniumâ€. Therefore, enjoy the good reputation of "keeping healthy and filling jade, and eating longevity and eating black dolphins". High-grade game and famous dishes made of black puffer meat have been popular in Southeast Asia and Hong Kong, Macao, Guangdong, Fujian and other large and medium-sized cities along the coast, forming a hot consumer demand.
Black porpoise has the characteristics of easy feeding, good management, strong disease resistance, no plague threat, low cost, and high benefits. The black porpoise breeding is a newly started characteristic breeding new project. The following describes its breeding techniques.
First, site selection: To choose a dolphins in a high-lying, dry, flat, well-drained, sunny place, which can reduce the incidence of black porpoise. In the construction of a mountainous area, care should be taken to avoid winds, slopes and other places to prevent winter storms and summer floods from forming in order to avoid unnecessary losses. The dolphins should be protected against rain, moisture, dogs, and rodents. In the winter, they can prevent cold and heat in the summer. They should try to maintain a certain distance from other animal houses and livestock houses so as to prevent epidemics and reduce disease.
Second, cage, box, pool construction cage type: General dolphins cage length, width, height 60 cm 40 cm 35 cm.
Box type: For the qualified professional black porpoise farm, the dolphins box can be specially made according to the specification of the dolphins cage.
Pool type: This is the simplest farming method. This method is suitable for large-scale rural farmers. It is easy to build pools, bricks, cement, wood, bamboo, adobe, fences, etc. can be used to build the pool. The aquaculture pond can be made into a rectangular shape, and the pond is divided into several small lattices of different specifications. The specifications of the various small compartments are: species of dolphins 60 cm 40 cm 30 cm; generally it is appropriate to breed 10 to 20 black dolphins per square meter. Plane culture is suitable for cement ground, so that it is easy to clean the excrement and reduce the occurrence of diseases. Special attention should be paid to the fact that the threat of natural enemies must be strictly prevented in plane farming, especially for domestic dogs. Once they enter the farm, they will cause great losses. The weasel and rat can spread some infectious diseases, and they kill small black dolphins in severe cases.
Stereo type: Stereo breeding is a culture method in which box-type breeding boxes are stacked together. Its characteristics are that it can make full use of space, is relatively centralized, easy to manage, and has a small footprint and a large amount of breeding.
Third, feed with green feed: Green feed accounts for 80%. Such as a variety of wild weeds, cultivated pasture, a variety of plant stems and leaves, vegetables, sweet potato vines, leaves and so on.
Hay Hay: Blue hay accounted for 10%. For example, corn sticks, wheat straw soybean root, peanut vines, etc. are generally dried with green feed, and then processed and crushed and then fed into the energy feed to feed black dolphins.
Energy feed: Energy feed accounts for 5%. The proportions are as follows:

IV. Rearing and Management of Black Dolphins Management of Baby Dolphin During Lactation: Black dolphins are fertilized through mating, and the average gestation period of female dolphins is 65 days. The black porpoise is called a porpoise 1-20 days after birth. If breast-feeding puffer fish does not pass water, 5 grams of quail can be brewed with open-water bubbling and chopped into the female dolphins feed. The female dolphin can quickly pass through the milk; if the lactating puffer does not have enough milk, or the female dolphins do not suckle , Or excessive birth of a child or postpartum mother dolphin death, all need to be artificially assisted breastfeeding. The method of artificial breastfeeding is to make a breastfeeder with eye drops. Breast milk can be used for milk products, goat milk, human milk, milk powder, milk yellow syrup can also be used, that is: 1 egg yolk plus 100 ml of milk or soy milk, plus appropriate amount of warm boiled water modulated into a thick. When breast-feeding, the milk is loaded into eight self-made breast-feeders, and the eye-dropping bottle is gently pressed by hand so that the milk can be slowly dripped into the mouth of the baited porcine. Do not be too eager when dripping milk, breastfeeding 1-2 times a day. Feeding should not be excessive at the beginning of feeding, usually 5 to 10 ml each time. For over-littering or insufficient milk, you can also find a “nanny†to support. On behalf of the family, use a little perfume on the “maternal†and on behalf of the puffer dolphins, so that they can not smell, or “nurses†will refuse to support. The suckling period of black porpoise cubs is 15 days in summer and 20 days in winter.
Feeding and management of young dolphins: Abyssinian weaners are called young dolphins after weaning. The key to raising young dolphins is to strengthen the feeding and management, prevent the occurrence of diarrhea and pneumonia, reduce the death of the city and increase the survival rate. At the same time, regular detoxification of Chinese herbal medicine such as Houttuynia cordata, Didanlong, Yinhua, etc., followed by adding to the feed to feed young dolphins, has a good effect on preventing the occurrence of pneumonia in juvenile guinea pigs.
Adult black porpoise breeding and management:
(1) Feeding in separate ponds or in separate cages. After the young dolphins have a stable diet, adult dolphins can be reared and managed in separate ponds. In order to prevent the phenomenon of close relatives in early marriage, it can be divided into male and female groups. 8 to 10 can be placed per square meter.
(2) The principle of feeding and feeding at regular intervals is based on the principle of less vote for breakfast and more for dinner. Some conditions can be added at noon some green feed, usually the amount of each black puffer daily for the 300-500 grams of green feed, refined to 20-30 grams. Every 10 days or so, add some herbs such as razor root roots and andrographolide to clear heat, detoxify and reduce inflammation, increase appetite and reduce disease.
Breeding of dolphins: Breeding dolphins, both males and females, must choose good broodstock with good body and nutrition, bright black hair, full spirit, and strong pain.
(1) Selection of male dolphins: In addition to the above-mentioned standards, male dolphins must be plump and plump, with positive limb shape, symmetrical testes, uniform size, obvious penis, and strong sexual desire.
(2) The choice of female breeding dolphins: The mother breeding dolphins must be tame, do not panic, normal vaginal development, more calving, with good, breast fullness, prominent nipples, lactation ability.
Capture of black porpoise: black porpoise scare scared, tame not bite, capture, with the right palm press the back of the black dolphins, and hold with your thumb, pay attention not to oppress the dolphins right shoulder, chest and stomach, gently Pick it up and then use your left hand to hold the whole body of the dolphins. In particular, catching pregnant female dolphins in particular must be strictly in accordance with the above requirements, and to be pregnant after the dolphin quiet, support his chest with his left hand, support his abdomen with his right hand, gently hold the pregnant mother to prevent capture Fear caused miscarriage.
Black Dolphin Transportation:
(1) The black vein transport should do a health check. Excessive wasting, sick and immature black dolphins cannot be transported to avoid death or miscarriage on the way.
(2) It is advisable to transport the dolphins baskets in plastic baskets that are 50 cm long, 35 cm wide and 15 cm wide. Transportation is most suitable for transportation in the beginning of spring, late autumn and early winter season. High temperatures in summer exceed 35 °C without transportation.
(3) The density of the dolman cage should not be too large when loading the vehicle. The bottom of the cage must be covered with paper and the position should be scientific.
(4) Transport should be protected from the sun and rain and pay attention to ventilation. The transportation time is suitable for morning, evening and night. Transport in winter should be cold-proof to prevent black dolphins from frostbite or freezing to prevent respiratory tract diseases caused by black porpoises. Special management during transportation, regular inspection, regular feeding.
V. Prevention and cure of common diseases of black porpoise The black porpoise has a very strong vitality and is generally not susceptible to infection under normal management conditions. However, the prevention of black porpoise diseases must not be neglected. The principle of “prevention over treatment†should be kept in mind in culture. Black dolphins have the following common diseases:
1. Causes of diarrhea: Causes of diarrhea vary widely, mainly from bacterial infections, such as eating diarrhea, frost, indigestible, unclean fodder, or overfeeding and dolphins wet, dirty utensils can cause diarrhea.
Symptoms: Infected dolphins suffer from loss of appetite or refusal to eat, tightening of the abdomen, faecal adhesions to the anus, and rapid weight loss; only moderate excretion of fecal material occurs before the disease.
Prevention: It is mainly to pay attention to keeping hygiene. Do not eat spoiled feed, drinking water should be clean without pollution. The utensils should be cleaned and disinfected regularly, and some antibacterial agents such as oxytetracycline and sulfadiazine should be fed regularly in the feed.
Treatment: Oral oxytetracycline 0.125 g, or 0.125 g sulfa fat, once a day, even feed 3 days or 1-2 drops of Huoxiangzhengqi water, 2 times a day, and even served 3 days.
2, pasteurellosis, referred to as the cause of pneumonia: black dolphins often have Pasteurella in the nasal mucosa, when the porpoise housing poor hygiene, poor ventilation, excessive feeding density, poor feeding and management, will make the bacteria multiply, causing nasal valve inflammation Nasal endocrine pus-like mucus, and often secondary to pneumonia, bronchitis and so on.
Symptoms: The sick dolphins often sneeze and erupt out of serous, mucinous, or purulent nasal fistulas as the condition progresses. When inflammation develops into bronchitis, coughing occurs. When the lungs develop lesions, the porpoise suffers from difficulty breathing and can only breathe openly and become restless. Do not eat, severe symptoms such as trembling, delirium and phlegm die. Anatomy of dead dolphins, visible respiratory and pulmonary congestion, bleeding, nasal cavity, laryngeal, tracheal full of mucus.
Prevention: The dolphins should be kept clean, dry and ventilated, and the stocking density should not be too large to prevent the cool air from blowing directly into the dolphins and feeding more vitamin-rich Ken feed.
Treatment: Honeysuckle 5g, chrysanthemum 3g, Solidago 3g boiled water plus feed in the feed, once a day, even for 3 days, or 0.025g sulfadiazine dissolved in water to feed feed, daily 2 times, even for 3 days.
3, the cause of subphrenic abscess: mainly streptococcal infection.
Symptoms: These diseases occur in adult dolphins. They present as abscesses with different symptoms under the jaw.
Prevention: Pay attention to the strict selection and breeding, and all the infected dolphins cannot be used as breeding dolphins.
Treatment: First, resection of pus, surgery, hair removal, routine disinfection. A 1-2 cm incision was made with a surgical blade at the abscess prominence, the toothpaste-like pus was extruded, the pus was eliminated with sterile cotton, and the incision was disinfected with 5% iodine, without suturing. Second, the anti-inflammatory drugs dissolved in water and fed into the feed, such as 0.25 g sulfadiazine, 2 times a day.
4. Causes of constipation: The main reason is the overfeeding of lean diets and the lack of green feed.
Symptoms: In the early stages of illness, a small amount of dry ball feces can be excreted. After that, it is difficult to excrete feces, and even after a few days, no feces are discharged. At the late stage of illness, the intestines often become inflated and the diseased dolphins are depressed. They often do not move on one side and do not eat grass. Sometimes they drink a little water and their fur is rough.
Prevention: Pay attention to feeding green and green feed, and use coarse and fine feed to be even and not partial eclipse.
Treatment: Oil 3-4 ml, a little salt, add 20 ml of water and feed them after mixing the feed, or mix the daily leftovers into the feed and feed them.
5, the cause of coccidiosis: the disease is caused by coccidiosis black porpochoid parasites; mainly in the warm and rainy season.
Symptoms: Poultry loss of appetite, abdominal swelling, diarrhea, often dilute fecal contamination in the anus near the coat, the sick dolphins depressed, body weight loss, and finally failed to die.
Prevention: Care should be taken to keep the breeding site clean, dry, and ventilated. The manure should be kept away from the dolman's hut, and often the chopped garlic is mixed in the feed for feeding. All have preventive effects.
Treatment: First, feed with 0.08% chlorophenylguanidine mixture, once a day, and feed for 3 to 5 days. Second, the sulfamethazine was fed, and 0.1 g was administered per kilogram of feed, and was even served for 3-5 days.
6. Causes of dolphins: dolphins are parasitic parasites on the skin of black dolphins and are a common disease.
Painful: When you open the body of a black porpoise, you can see tiny burrows, especially in the head of black dolphins.
Prevention: Disinfect dolphins on a regular basis with Tetrim and other drugs.
Treatment: The black dolphins are fed with the larvae in the feed, and the guinea pigs are treated comprehensively once a month.
7, swelling disease, also known as the cause of bloating disease: Feeding spoilage feeds, drinking contaminated water bacteria, leading to indigestion and cause the disease.
Symptoms: Loss of appetite or stagnation in sick dolphins, shortness of breath, difficulty, lack of energy, belly bloating, and fullness and softness of hand presses, diarrhoea in post-illness diarrhoea becomes thin or water-like blue-green or yellow-green. .
Prevention: Dewy grass should be dried and then fed. It is forbidden to feed degenerate feed and sewage, and to control the feeding of vegetables with excessive water content.
Treatment: First, if there is gas in the stomach, you can add a small amount of fennel oil, or add 2 to 3 drops of Huoxiangzhengqi water. Second, traditional Chinese medicine can be fed with cloves of lotus root, 1 to 2 times a day, and then fed for 2 to 3 days.
The above is the efficient breeding technique of black porpoise. Black-breeded dolphins have high economic benefits. If they are 50 pairs of black dolphins in their free time, the annual income can exceed 15,000 yuan. If the hand-cultivated 200 pairs, the annual income can exceed 60,000 yuan, which greatly exceeds the benefits of breeding pigs. , chickens, ducks, geese and other traditional livestock and poultry. Practice has proved that farmers want to make a fortune, and breeding black porpoise is a good project.
