Artificial cultured hedgehogs
Hedgehog is a kind of medicinal small beast, skin known as different incense, fairy clothes, is a traditional Chinese medicine, artificial breeding hedgehog profitable. First, the construction of the farm. Hedgehog is calm and afraid of the light, and stays indoors. The venue should be built in a quiet place where no one interferes. A courtyard was built and the wall height was about 0.8-1 m. The inner chamber was a connected nest and outer nest. The inner nest room was a nest, and hay, pine leaves or straw were laid. The outer nest room is an activity place, building mounds or rockery, planting flowers, grasses, shrubs, etc., for their foraging, mate finding and inhabiting. Generally 10m2 site can raise 30-50. Second, feeding. Hedgehog is a nocturnal animal and can be fed with feed and water before and after the evening. The feed can be artificially mixed evenly and cooked. Formula: corn powder 30%, wheat bran 20%, fine rice bran 10%, fish meal 5%, vegetable 30%, bone meal 2%, iodine salt 1%, terramycin powder 1%, amino acid 1%, trace element amount. Wild domesticated hedgehogs will be domesticated domestically, and animal feed will account for 80% of the diet. Gradually increase the plant feed. The feed must be fresh, clean, and immersed in fruits and vegetables. Feed should be diversified. The standard of locust rations is: 50g for 50-150g, 150g for 150-300g, and 150g for 300-600g. Hedgehog eats large amounts in summer, grows fast, sleeps in winter, and eats very little. Third, breeding. Domestic hedgehogs should have a male-female pair, usually estrus mating from April to May, with an annual output of 1-2 fetuses, and 2-4 year-old hedgehogs have reproductive ability. Female locusts are irritated during estrus, and there are secretions in the genitals. Pregnancy lasts for about 60 days. Each litter has 4 to 6 litters and up to 8 babies. After 30 days of fertilization, Hedgehog had gained weight, had sluggish 45 days, mild edema of the perineum, and had no choice but to find a nest before labor. The newly born Aberdeen had soft thorns and no hair. About 20 hours later, the soft thorns were erected and a squeak was heard. The birth weight 13-15g, Aberdeen took three days to soften the spines to become hard, gradually increased, 10 days old eyes, 20 days old teeth and walk, can eat about 30 days of age, breastfeeding 40-50 days. The average weight of a 3-month-old hedgehog is 320-350g, and the average monthly weight gain is about 100g. Between the lactation period and the 100-day period after breast-feeding, it is the fastest growing phase of the hedgehog, and it must be carefully managed to ensure and improve the skin's Quality and length. Fourth, disease prevention and treatment. Hedgehog common diseases are gastroenteritis, skin lice, and tsutsugamushi disease. Suffering gastroenteritis, dullness, walking weakness, diarrhea, refusal to eat. The feed can be reduced, oxytetracycline can be fed, and each piece can be fed into the feed and fed three times a day. Gentamicin can also be injected, intramuscular injection of 25,000 units per hip. Suffering from skin rashes, removing white crumbs, rubbing creams, skin light creams. Can also be used 24 hours after the vinegar impregnated with tobacco, add trichlorfon (crushed in) rubbed the affected area. Suffering tsutsugamushi disease, loss of appetite, drowsiness and inability to feed the locust net, feeding 2 times a day, each time, even fed 2 days. For hedgehogs not suffering from tsutsugamushi disease, they must be mowed twice a year to check whether the hedgehogs are strong, if they look at the glossiness of the thorns, whether the body is plump or not, and see the tightness of the thorns.
