Breeding techniques of golden head turtles

The meat of the beetle is delicious and delicious, which is better than the golden tortoise. it is an advanced tonic, and the belly nail can process many kinds of proprietary Chinese medicine. Golden-headed turtles are antique, have high appreciation value, and are high-grade animals for export. Golden head turtles have the advantages of simple feeding, high reproduction rate, fast growth, small investment and good economic benefits. For this reason, the characteristics and feeding techniques of golden head turtles were introduced.

Biological characteristics

Golden head turtle, commonly known as yellow edge closed shell turtle, originated in the south of the Yangtze River basin, the head is smooth and scaleless, there is a golden wide arc pattern behind the eyes, so it is called golden head turtle. What is interesting is that the belly armour is not connected to the tortoise's back shell and closes up and down like a loose-leaf chain. When the enemy is attacked or frightened, all the head and tail limbs are retracted into the shell without revealing any flesh. Golden head turtles belong to semi-aquatic, like to live in the water, frightened that dive into the bottom, but also can be separated from the source of long-term survival. The turtle has the habit of living in groups, at least two live in caves together, seven or eight for a long time. It hibernates from November to March of the following year, and begins to come out in April. It is seldom active during the day in the changing temperature season, and the same kind does not fight each other or bite people. When the temperature was below 20 ℃, they basically did not eat, but began to eat at 24 ℃. The period from June to October is a prosperous eating period. the temperature drops in November and food consumption decreases gradually until

Stop eating and go into hibernation. Eating is usually in the evening to the next morning. A wide range of food, wild to insects, snails, tender plants. Under the condition of artificial feeding, animal drinks, such as small fish and shrimp, snails, earthworms, maggots, etc. are mainly fed with plant feed, and the annual weight can be increased by 250 grams.

Golden head turtle has the ability to kill snakes, it uses the upper and lower opening and closing decks to clip snakes to death, bite and eat, so it is also called sipping snake turtles. The turtle is so spiritual that it will crawl back to its hometown even after a few decades. The domesticated golden head turtles will not go away even if they are placed in the courtyard, and when strangers come, they will make a clapping sound to inform their owners.

Farm construction

Golden-headed turtles can be raised in dry or semi-dry conditions. Dry farming can be surrounded by planks indoors, in a corner of the courtyard and on the balcony. Can also be made of cement or masonry into a 50 cm high low wall, the edge of the wall painted flat, to prevent turtles from escaping. For example, a pool is built on one side or in the middle of the fence, which can fill more than 25 centimeters of water. There are drainage holes in the pool, which are usually closed. A number of water basins should be set up in dry farming, and the turtle ponds should be covered with sand 10 to 20 centimeters thick to facilitate female turtles to lay eggs. Turtle pond should be built in the leeward to the sun, sufficient water, not easy to be polluted, secluded and shaded place. Even if dry farming, the turtle farm should be washed with water frequently to keep it clean. The size of the pond can be determined according to the scale of feeding.

Feeding and management

1. Feeding density: the indoor and outdoor feeding density is the same. Generally, adult turtles (more than 200 square meters and 250 grams per square meter) are reared in 3 groups (1 male and 2 females in each group), 20 young turtles, 30 young turtles and 30 young turtles.

2. Feed

① feed varieties: small fish and shrimp, shellfish, earthworms, silkworm pupae, moths, insects, frogs and all animal meat and viscera, with cereals, fruits and vegetables and duckweed, raw and cooked. Large chunks should be chopped and dirt should be washed. When feeding whole grains, soak in advance and soften.

② feeding amount: once a day, each feeding should be about 7% to 10% of the tortoise's body weight, which should be increased appropriately in summer.

③ feeding time: the temperature is low in spring and autumn, so it should be fed at noon. Summer should be fed before 9: 00 a. M. and after 7: 00 p. M., and the feed delivery point should be fixed for a long time.

④ feed nutrition: feed more protein-rich and digestible feed and various vitamins, and add appropriate amount of livestock and poultry auxin twice every 10 days to improve fecundity and fertilization rate.

3. Overwintering management: hibernating when the temperature is below 13 ℃, cover a corner of the turtle farm with warm or wet sand, straw, rags and old quilts, and then cover with rain and snow to keep the temperature above 0 ℃. Outdoor breeding should be covered with plastic film to prevent icing. It can also be transferred to indoor tanks, pots, buckets and other containers for the winter. However, these containers should also be covered with heat preservation and checked every 7 days. If it is too dry and the turtle is white, it should be drenched with water. The water temperature is the same as that of the overwintering ground, not more than 3 ℃ up and down.

4. Reproduction and hatching

① reproduction: turtles weighing more than 200 million 250 grams have the ability to reproduce. In order to improve the reproduction rate, it is better to take 1 male and 1 female as a group of breeding population. The male tortoise is slightly longer and the back is slightly low and narrow; the female tortoise is slightly round and the back is high and wide. Mating began in the middle of April. The spawning period is from May to September. The female turtles lay 3-7 eggs each time and lay eggs 3-4 times a year. The egg white is oval and the maximum egg weight is 36 grams.

② ovalization: use a wooden box, the bottom of the box to make several holes to facilitate leakage, the box covered with 3 cm thick wet sand, the turtle eggs in turn arranged on the sand, tilting at a 45-degree angle, big head up, small head down, the distance between the eggs and eggs is about 3 cm, cover the eggs with 3 cm wet sand, and then put the second layer of eggs, cover with wet sand and cover with moisturizing, check every 2 days. If dry, it can be moisturized with a small amount of water. In the temperature range of 22 ℃ ~ 38 ℃, it usually comes out of the shell in about 60 days. After hatching, the juvenile turtles will arch out the sand, climb to the top, wait for the umbilical cord to fall off, put it into 5000 times Gill potassium solution and disinfect it for 5 minutes, and then put it into a shallow water basin for half a month. To feed cooked egg yolks or chopped earthworms, change the water every two days to keep the water fresh, and then transfer to dry or semi-dry farming.

5. Disease prevention and treatment: Golden head turtles generally do not get sick. But the feeding is not fresh or poor hygiene in summer, will cause gastroenteritis, can be injected with chloramphenicol, weight 500 grams of turtle dosage of 0.2 grams, or with fluoric acid 1 beat 4 tablets mixed with chopped pig lungs to feed. If turtles catch a cold in winter and spring, you can add Cefalexin, ribavirin or SMZ to the feed, using 3 tablets for every 500g turtles, or injecting 15000 units of micronomycin.

Small turtles should pay attention to prevent rats, dogs, cats and other enemies, to prevent poisonous substances from polluting food. Toxic drugs should not be used in the breeding ground to prevent strong acid and alkali substances from coming into contact with the tortoise body.
