These test kits are new to the market and rely on the detection of viral proteins in swab samples They consist of monoclonal antibodies specific for the viral antigens and results are seen by the naked eye by way of chromatographic particles. There have only been a few of these tests commercialized and normally require a high viral count to work effectively. In the first few months of the pandemic some national health authorities questioned the reliability of these tests, as they usually require a higher viral count that qPCR to show positive. Therefore, false-negatives can occur. antigen test kit, rapid antigen test kit, covid-19 antigen test, antigen detection, antigen rapid test kit Shenzhen Uni-medica Technology Co.,Ltd , https://www.unimed-global.com
(1) Living habits Snapping Turtles can survive in water temperatures from 3 to 45 degrees Celsius, are most active at 20 to 30 degrees Celsius, grow fastest at 28 to 31 degrees Celsius, enter hibernation below 15 degrees Celsius, and do not under 0 to 5 degrees Celsius in ice. Will freeze to death, over 1 degree Celsius can safely over the winter. Snapping Turtles enjoy a quiet habitat and have a mixed diet. They like to eat aquatic animals and aquatic animals. They can eat dead animals, fresh grass leaves and flowers and fruits on the shore. Feeds for artificial rearing include: fresh fish, shrimp, snails, cockroaches, insects, cockroaches, silkworm cocoons, fly pupae, yellow mealworms, livestock and poultry viscera and waste, and extruded feeds.
(2) The construction of the rearing pond is built to a depth of 1 - 1.5 meters and the shape area is not limited. Leave 10% to 20% of the land on the ground as spawning ground. Masonry is done on the pool and smoothed with grout. The spawning ground can be treated with grout and put 40 cm thick sand. The spawning site should be sloped at 45 degrees and covered with wood or foam to prevent it from being scratched. Pool week should be built 1 - 1.5 meters high escape protection wall. Small breeders can use pots and cover them with nylon nets. For instance, turtles should be built with a fixed-size cement pool, and new cement pools should be sterilized with 15 - 20 mg/kg bleach and soaked with 0.1% superphosphate solution. 1 - 2 days before the turtle can be placed.
(3) Feeding and management 1 Grading pool stocking for each square meter can be stocked with 1 group of turtles (1 male and 2 females), or 3 groups of medium turtles, or 5 to 10 groups of hatchlings, or 10 to 20 groups of hatchlings, according to size. Different sub-pool feeding, can not be mixed, so as not to affect the growth of small turtles.
2 Fixed-point, regular-time and quantitative-feeding 1st feeding at noon in early spring and early winter. The end of spring and late autumn is the season of snapping turtle feeding. 2 times per day, 90% at 9:00, and 60% in the evening, the feeding should be fixed. - The amount of bait that is dropped can be eaten within 2.5 hours. If you do not eat enough food, you can make fewer shots. Food should be cut to large, hard to soak up, regardless of raw and cooked. The young hatchling feeds nutritious crushed bait and is prohibited from feeding modified bait. The bait is mainly based on animal foods, and it is appropriate to mix some vegetable, fruit and vegetable foods, and also use soft-shelled turtle feed.
3 Change the water regularly and disinfect the pool with large area. Change the water once every 20 - 50 days, change the water in the small pond for 2 - 3 days or 6 - 7 days, and keep the transparency of the pool water at 10 - 20 cm. Change water as little as possible according to the situation in the winter, but the pots should be changed in time. Pool water - usually 20 - 30 days with 10 mg / kg bleach to disinfect against turtle disease.
4 Summer heat should be kept to a depth of 80 cm in the pool and shading more than 1/2 in the pool. Keep some duckweed in the pond and grow trees around it. If necessary, cool the new water so that the water temperature does not exceed 45 degrees Celsius.
5 Breeding and hatching Wild snapping turtles begin to lay eggs in the fifth year, while the captive snapping turtles begin spawning in the third year or weighing more than one kilogram. Natural mating occurs in April-May and September-October, and spawning season occurs in May-August. Female turtles spawn during the day and are divided into 2 - 3 births, spawning 11 - 50 eggs at a time, spawning 30 - 120 eggs a year.
Incubation method: The incubator is 80 cm high, 50 cm wide, and 80 cm long. Several leak holes are drilled in the bottom of the box. The first 5 cm of coarse sand is placed first, then 5 cm of fine sand is placed, and the eggs are placed on the sand (animals with white spots). Extremely up, cover 5 centimeters of fine sand and cover it to prevent rats and snakes. The coarse sand used was sterilized with boiling water. Check once a day. If the surface is dry on the surface of the sand, it should be moistened with water. Hatchlings hatch at a natural temperature of 65 - 75 days. The hatching rate is 93% - 96%. If the temperature is 30°C and the relative humidity is 80% - 90%, hatchlings hatch after 50 - 60 days. The rate is 98%. After hatching, hatchlings are allowed to move in the incubator for several hours until they are detached from the umbilical cord. They are then transferred to a 200 mg/kg potassium permanganate solution and sterilized for 5 minutes before being placed in a clear water tank.
(4) Disease prevention and control As long as the turtle and pool water are strictly sterilized, it is rarely diseased, there are occasional minor illnesses, and the right medicine is prescribed and is easy to treat. Trauma inflammation and colds can be treated with vanguardomycin compound; gastroenteritis can be fed norfloxacin; indigestion can be served multiple enzyme tablets or yeast tablets; hydromycotic net solution can be used to dip for 15 minutes or with saline Soak the sick turtle.
Snapping Turtle native to North America and Central America, also known as small crocodile turtle, in recent years, China introduced artificial breeding to be successful. Snapping turtles are known for their strong body and flesh, so they are also known as meat turtles. They have high meat yield, rich nutrition, fast growth, and high economic value. Its meat yield ranks first among turtles, reaching 85%-89%. Snapping Turtles have an average annual weight gain of 550 - 1100 grams, which is several times that of an ordinary turtle. Snapping turtle meat is delicate, crispy, delicious, and no peculiar smell, nourishing effect is very obvious, there is Yin and blood, Yi Jing Qi and other effects, after a long illness, blood deficiency, fatigue, fatigue, weakness, cough, sputum are There are obvious effects, especially for postpartum anaemia, insomnia and mental decline. Turtle plate has a swelling effect, suitable for cancer caused by yin deficiency, blood deficiency body consumption. Turtle blood and glans also have medicinal properties. The key farming techniques are now described below.
