Ducks eat mostly aquatic food, so their meat tastes sweet and cold, and enters the lung, stomach and kidney meridians, which has the functions of nourishing, nourishing stomach, tonifying kidney, removing tuberculosis, steaming bones, eliminating edema, stopping dysentery, relieving cough and resolving phlegm. It is suitable for people with heat in the body to eat duck meat, which is of great benefit to people with weak constitution, loss of appetite, fever, dry stool and edema. Duck meat has a good therapeutic effect on tuberculosis, so it is called the "holy medicine" for tuberculosis patients. As early as a long time ago, China's medical book Compendium of Materia Medica recorded the dietotherapy effect of duck meat.
Besides, duck meat contains the healthiest fat. Duck meat is rich in vitamin B and vitamin E, and its fatty acids are mainly unsaturated fatty acids and low-carbon saturated fatty acids, which are easy for human body to digest. The fat in duck meat is different from other animal oils, which has the function of lowering cholesterol and is very suitable for patients with atherosclerosis. Besides, eating duck meat is also good for the heart. 100g duck meat contains about 300mg of potassium, which is related to heart rhythm. High potassium content can offset the increase of sodium content in the body caused by eating too much salt, which is beneficial to relieve hypertension. Therefore, it is very healthy to eat more duck meat instead of other meat dishes in daily life.
Ducks over five years old are the best. Ducks are different from other animals. The older you get, the lighter you get. Some old ducks look big and light in their hands. The harder their old bones is, the harder they bite. Old duck soup is not hot in their mouths. Generally speaking, eating old duck soup is good for minor ailments. We sell 100 ducks a year here, and it will cost about 800 or even 1000 in five years. Generally speaking, it is good for farmers to grow up eating miscellaneous grains.
Old ducks should be kept for more than three years. First look at the cocoon thickness on the duck's paw. If it is thick, it is an old duck. Besides, old Abby Mallard ducklings are thin, but their bones are hard to catch with their hands. The old duck must buy a female, and the male is not delicious.
I often eat old duck soup, which is said to be very nutritious, but I just don't know how many years the so-called "old duck" has been fed and how to judge the age of the duck.
Thank you for inviting me. There are many kinds of ducks, including Ma duck, Ka duck and White duck. The life span of ducks is about ten years. It is often said that old duck soup has high nutritional value and is a tonic. Generally speaking, ducks of five or six years old are the best, the most valuable and the most sought after. We have people here, and most people buy them because they need them. There were several when I bought them, saying that they were physically weak and eating old duck soup worked. Generally speaking, Ma duck is the best, followed by Ka duck. White ducks are rarely raised, because the meat of white ducks is not as fragrant as Ma duck and Ka duck. The picture comes from the internet.
As the saying goes, "a thousand-year-old turtle is easy to find, but a decade-old duck is hard to find." The life span of ducks is only ten years at most, with an average life span of seven or eight years. It is said that ducks over a few years old have high nutritional value and are really exquisite.
Ducks are not more nutritious as they get older, which is different from ginseng and ganoderma lucidum. On the contrary, ducks over a certain age will cause the loss of nutrition, and muscles, brains and cells will shrink when they are too old.
Ducks have the highest nutritional value when they reach half life. According to the average life span of seven or eight years, that is, ducks with four years or so have the highest nutritional value and are the best to eat. They are usually used to make soup.
Generally, few people sell old ducks over four years old. Because of the high cost of breeding, the female ducks sold in the market are generally two or three years old, and the egg laying rate has dropped before they are sold, but they are also very nutritious.
As a post-70s generation, when I was a child, every household had a chicken nest, and chickens and ducks were raised at home to lay eggs and adjust their lives. Feed the chickens and ducks to the children at home. At that time, the happiest thing was to come home from school and cut some leaves and throw them to chickens and ducks, or catch some bugs to eat. Sometimes I go to the seaside to get some seaweed and oyster shells and mash them for chickens and ducks.
When the chickens at home are cackling and laying eggs, it is particularly exciting to go to the chicken nest to pick up a hot egg. Ducks don't lay eggs like chickens. It's a headache to go anywhere, but ducks are not as sick as chickens, and they are easy to raise.
I remember clearly that there was a big white duck at home as long as I can remember, and my father said it was bigger than me.
This big white duck may be old and has been wobbling. Moreover, other chickens and ducks eat it when eating, which is quite "elder style". Another feature of this great white duck is that it can recognize people. Every day when I come home from school with my schoolbag on my back, it must flap its wings at you and be very excited.
I clearly remember that my father said that this big white duck had been raised for more than nine years, and later I don't know why this big white duck "ran away from home"! Never came back, the old man said, "chickens, ducks, geese and dogs never die at home"!
As northerners, we seldom eat ducks here before. The main purpose of raising ducks is that they are less likely to get sick than chickens, and the eggs laid are big enough to be pickled. There is also that green duck eggs can be fried to relieve cough for children (old people say so, I cooked them at home when I coughed when I was a child, and the effect is not clear).
With everyone's publicity, it is said that eating duck meat is good, and we belong to the seaside here, and there are many people raising ducks. Some ducks will be disposed of in winter, especially drakes with green necks, which are worthless and everyone will buy them to eat. Especially in recent years, with the rise of street roast duck, ducks that didn't like eating much before have now become hot items. Especially in summer, everyone thinks that the old duck has nourishing function, so the old duck has become a "hot commodity" in the rural market.

When I was a child, my grandfather got sick and had an operation. My mother fed the old duck for six years to my grandfather. At that time, my heart was reluctant, because the duck was fed for six years and my feelings were deep. The duck I keep at home has small gray feathers and a slender body. This duck has a high egg production rate. Is the ordinary duck short and thick Bob?
