Why do you keep turtles in the temple?

The tortoise is said that Dayu's father, then called Gun, was a huge basalt. At that time, the Yellow Emperor asked him to control water, and he only knew how to stop water. As a result, the flood did not leak. So it took a lot of manpower and material resources, and finally it didn't win the prize for water control. Later, Dayu refused to enter the three countries, and finally succeeded in harnessing water. As the embodiment of the gun, SHEN WOO was once again admired by people. Ancient temples were built at the expense of the emperor, so many temples also have statues of the Yellow Emperor. In order to feel Dayu's relief well, several turtles were raised to show their respect.

2, in order to see the water quality safety

In ancient times, people were afraid of poisonous wells, so they raised turtles to see if the water quality was poisonous. Shaolin Temple has experienced wind and rain for a hundred years, during which many people tried to harm Shaolin Temple. At that time, the temple presided over raising water turtles, considering that monks drank well water for a living. If they were poisoned, the whole temple would be in danger, so two turtles were released. Outsiders think it is a monk's compassion, but in fact it is to see the safety of water quality.

Extended data

Nutrients needed by soft-shelled turtle are mainly protein, fat, carbohydrates, inorganic salts and vitamins.

1. protein. Protein is the most important to the growth and development of turtles. Turtles take protein directly from feed. It is generally believed that the high content of protein in feed will make the feed have good nutritional value and the breeding objects grow fast. Soft-shelled turtle has a high demand for protein content in feed, and the demand is different at different growth stages. Generally, the content of protein in feed is required to be 38% ~ 42%.

2. Fat. Fat is one of the indispensable ingredients for the growth and development of soft-shelled turtle. Mainly used as body fat stored in the body or as an energy source for exercise. Generally, the thermal energy released by fat oxidation of soft-shelled turtle is twice that of sugar and protein. The experiment shows that the fat content in turtle compound feed is 3.5% ~ 5.0%. Too high or too low will affect feed efficiency, weight gain rate and meat weight gain coefficient.

3. carbohydrates. The main physiological functions of carbohydrates after being absorbed by human body are: one is to provide heat, the other is to form body components; The third is to keep protein in the body as a binder for feed. The suitable amount of starch in turtle feed is 23% ~ 26%.

4. Inorganic salts. Inorganic salts play an extremely important role in soft-shelled turtles, not only participating in the formation of bones and blood, but also directly or indirectly regulating the physiology of the body, especially the spawning and reproduction of soft-shelled turtles. Among the necessary inorganic salts, the following are easy to be lacking, such as calcium, phosphorus, sodium, chlorine, magnesium, zinc, copper and cobalt. Calcium and phosphorus account for 3/4 of all inorganic salts in the body, especially "efficient and fast-growing additives" such as bone meal must be added before and after turtle spawning.

5. vitamins. When turtles lack vitamins, their growth and development slow down, their metabolism is abnormal, and they are prone to various diseases. Most vitamins cannot be synthesized in the body and must be supplied through feed. Vitamins, like animal hormones, are small but essential, so multiple vitamins must be added to the feed.
