Flat-breasted turtle is the oldest living reptile. Mainly distributed in southern China and other places, it is the most special freshwater turtle in China. Its head can't be retracted into the shell, and its temperament is fierce, belonging to the national first-class protected species. ? Morphological characteristics of flat-breasted turtle:? Flat-breasted turtle, also known as Hawk-billed Dragon-tailed Turtle, is a peculiar turtle species. Its scientific name is Big-headed Flat-breasted Turtle, commonly known as Hawk-billed Turtle, also known as English Turtle and Dragon-tailed Kirin Turtle. Its long tail? Ba is like the tail of a dragon, with scales and strength. Its head, eyes and mouth are all like parrots. Some people call it parrot turtle, which is very cute. The head is large and triangular, and the back of the head is covered with a large horny hard shell. The upper beak is hooked like an eagle's mouth, with big eyes and no eardrum. The carapace is brown and oval, with a flat center and toothless front and rear edges. The ventral nail is olive-shaped, small and flat, and the dorsal ventral nail is connected by ligaments, and the angle plate is low. The limbs are gray, with flat scales and long hind limbs. In addition to the outer fingers and toes, there are sharp long claws, and there are half webbed fingers and toes, which is not only conducive to crawling on land, but also convenient for swimming in the water. ? Tails are very long, some of which have exceeded the length of their own carapace, and the tails are covered with short annular scales. The head and limbs of this turtle can't be retracted into the abdominal shell, and it is a special turtle known in China. Strong limbs and sharp claws. When crawling fast, it looks like a unicorn dragging its tail and courageously hooves. Look at the prey like an owl when squatting quietly, and take off like an eagle when walking sideways. This turtle is basically a combination of dragon, unicorn and turtle. The four great beasts in the history of China are dragon, phoenix, unicorn and tortoise. This turtle has three forms, only the phoenix is missing. So it is very ornamental. When this turtle meets an animal bigger than it, it will find a roar in its mouth, scaring off the enemy and not afraid of Shan Ying's attack. ? : ? 1. Feeding and management of young turtles The feed for young turtles is basically the same as that for parent turtles except that the particles are fine and soft, and the feeding amount is about 5% to 8% of the weight of young turtles, once in the morning and once in the evening. If you use artificial full-price pellet feed for young turtles, sprinkle it on the food table twice in the morning and evening according to 3% ~ 5% of the total weight. Such as artificial powdered compound feed, it should be fully wetted and kneaded for a long time to make it soft and sticky, and then fed near the water surface. There should be a shade shed on the turtle pond for sun protection, and fresh water should be added frequently to keep the water fresh, and the residual materials should be removed in time to prevent the water quality from deteriorating. In winter, young turtles should pay attention to keep warm in order to spend the winter safely. When the water temperature is lower than 65438 05℃, it can be covered with plastic film. ? Adult turtle? Parrot turtles eat a wide range of food, both animal feed and plant feed. To make them grow rapidly, animal feed should be given priority to, supplemented by plant feed, and various vitamins, trace elements and mineral feeds such as calcium and phosphorus should be added. The ratio of animal and plant feed should be 7: 3 or 8: 2. The feed should be fresh and fed on the day of processing, not with rotten food. The quality and quantity of feed depends on the different growth stages and climatic conditions of parrot turtles? Feeding management? Change. July to September every year is the peak period of feeding activities of parrot turtles, with the fastest weight gain. Therefore, we should provide adequate nutrition in these three months, so that they can eat more and grow faster. The temperature is low in spring and autumn. Parrots and turtles like to eat around noon, so they should eat before noon. The temperature is high in summer, and most of them feed from 5 pm to 7 pm. When the hibernation period approaches, the feeding amount should be increased to fatten the soft-shelled turtle, which is beneficial to overwintering. Before and during mating, parrot turtles should be fed with digestible feed rich in protein, vitamin A, vitamin D, vitamin E and vitamin D, so as to improve the fertilization rate and fecundity of parrot turtles. After 165438+ 10 months every year, when the temperature is lower than 15℃, parrot turtles will crouch in the sediment at the bottom of the pool, unable to eat or move, and go into hibernation. At this time, you don't need to feed or change water, but you should pay attention to heat preservation and cover the pool with straw and the like. It usually refers to spring, summer and autumn. Pay attention to changing the water in the breeding pond, every two days in summer and every five days in spring and autumn to keep the water clean and prevent turtles from getting sick. ? Turtle seedling selection? A healthy flat-breasted turtle has smooth body surface, complete epidermis and dorsal abdominal armour, full limbs muscles, bright eyes, sensitive response to the outside world, strong limbs when crawling, able to support the body, fast escape, fast swimming when entering the water and sinking to the bottom. On the contrary, turtles with weak limbs, unable to struggle with their hands, swimming slowly in the water or floating on the water for a long time should never be chosen. ? Turtle seedling stocking? Flat-breasted turtles are more wild than other turtles, and it is difficult to adapt to the environmental conditions of artificial breeding. The newly introduced soft-shelled turtle can't be put into the water immediately. It should be dried in the shade for 3 hours, and then properly sprinkled with water to keep the soft-shelled turtle moist. 1 day later, turtles can be put into the water and fed with live bait, such as live fish, shrimp, tadpoles, earthworms, etc. , you can feed. 10 days later, put the edible turtle into the turtle pond, and the water depth will be about 20 cm at first, and then gradually deepen to about 50 cm after adaptation. After the turtle takes the initiative to eat, it can be fed with bait such as chilled fish. The feeding order is to ice fresh fish first and then live bait, and both chilled fish and live bait should be put into water. ? Bait? In artificial breeding, eat small fish shrimp, earthworms, chilled fish and other baits are used for flat-breasted turtles. Before feeding, it is necessary to process large pieces of bait such as fish and shrimp into small pieces, which is convenient for turtles to eat. Bait is put into the water to adapt to the habit that flat-breasted turtles like to eat underwater. The feeding amount per time is 2%~3% of the turtle's weight, 1 time per day in summer and 1 time per day in spring and autumn. When the water temperature is lower than 20℃, it is not necessary to feed. The feeding time is basically fixed, and regular feeding is beneficial to the formation of conditioned reflex and easy to observe the feeding situation of soft-shelled turtle. ? Daily management? Maintaining good water quality is an environmental condition for raising flat-breasted turtles. So always change some water and then replenish fresh water. Change water in time after feeding. Flat-breasted turtles are not resistant to high temperatures. When the water temperature may exceed 30℃, they must be moved to a cool and low temperature place in advance to prevent the turtle from heatstroke. ? Precautions? The biggest feature of flat-breasted turtles is fierce and aggressive, and they often fight when raised in groups, resulting in disability. Therefore, it is best to raise them separately, and only/kloc-0 turtles per square meter can be raised in groups. Tortoise with trauma can be soaked in 40 mg/L potassium permanganate solution for 30 minutes, and then soaked in 5 mg/L Miao Bo disinfectant for 65438 0 days.
