Berries and grains. Strong feet and easy to walk, short wings, can't fly much higher and farther. The cry is monotonous and low. During the breeding period, nests are built anywhere in the grass on the hills, and hay and fallen leaves are spread in the depressions on the ground. Each nest lays 6 ~ 14 eggs, and generally, 2 nests are hatched 1 year. There are 19 pheasant subspecies in China.

During the Spring and Autumn Period, Zuo Qiuming wrote Mandarin? In this IV: "The Yellow Emperor has twenty-five sons, and fourteen sons have surnames, making a total of twelve surnames: Ji, You and Qi ..." The twelve surnames reflect the twelve tribes of the ancient Yellow Emperor. Among the twelve surnames, only chicken is one of the twelve branches.
Before the invention of the ancient timer, the rooster crowed in the morning to report the beginning of a new weather. It is not only the clock of farmers' families, but also the clock of public life. During the Warring States Period, the famous Hangu Pass was opened and closed on the basis of cock crow. Meng Changjun fled, facing the closed gate, worried that the pursuer would come behind him. Among the diners, there are ventriloquists who know the journal, calling all the chickens at once and cheating on opening and closing the door. This story was written into Historical Records by Sima Qian and passed down as a classic.
Customs about chickens in various places
The ancient Han nationality had the custom of "killing chickens", which was popular in Jinhua and Wuyi areas of Zhejiang Province. On the seventh day of July every year, local people will live there, because the Cowherd and the Weaver Girl will meet at Queqiao that night. If there is no rooster to announce the dawn, they will never part.
Tujia people call kicking shuttlecock "kicking chicken". During the Spring Festival, young men and women kick chickens together. One person kicks the "chicken" and everyone fights. Whoever receives the "chicken" can chase anyone with grass. Young men and women often chase their lovers with grass. In the future, "kicking the chicken" will become the medium of love.
On October 1st of the lunar calendar, some places in Henan will kill chickens to scare ghosts. Legend has it that Tomb-Sweeping Day will collect the terrible release ghosts in the coming year. People think that ghosts are afraid of chicken blood, which can ward off evil spirits, so they kill chickens on October 1 to scare ghosts and make little devils afraid to come out. As the saying goes, "October 1st, kill the goose that lays the golden egg."
In some areas of Shandong, there is a wedding custom of "holding a chicken". When getting married, the woman chooses a boy to hold a hen and leaves with the sedan chair to bid farewell. Because chicken is homophonic with "auspiciousness", it is auspicious to hold a picture of chicken. In addition, there was a custom of raising "long-lived chickens" in ancient times. When approaching the wedding, the man should prepare a red rooster, and the woman should prepare a fat chicken. The hen says that the bride is a "lucky person". When getting married, the rooster prepared by the woman must be led by her underage brother or other boys, set out with the sedan chair and arrive at the man's house before the rooster crows. People think that if the rooster doesn't sleep and the hen doesn't sleep, it is to overwhelm the rooster with momentum. Then, the man gives the rooster to the person holding the rooster, ties the rooster and the hen together on the leg of the table, and beats the rooster from time to time until the rooster faints, which is a symbol of the wife's surrender to her husband. After that, the two chickens are not allowed to be killed, so they are called long-lived chickens. In Zhejiang, the marriage custom of "killing chickens" is popular. The groom goes to the bride's house to get married, and the woman's house spreads a piece of white cloth on the ground, so that the groom can kill chickens on it. Chicken blood can't be dripped on white cloth, or a few drops will be fined several glasses of wine. When killing the chicken, the woman's family deliberately collided with the groom, but the experienced groom handled it well and wouldn't let the woman succeed.
The custom of "chicken rice ceremony" is popular among the Bai people in Dali, Yunnan. There are two kinds of chicken rice ceremonies: chicken rice single ceremony and double ceremony about rice. A single gift is a rooster and a jar of rice wine; Shuangli is a big cock with two sides and three knives, an altar of rice wine and an altar of rice seeds. This is a gift given to each other by first-degree relatives or in-laws at the time of birth, marriage and building.
In the old society, the communication custom of drinking chicken blood wine was popular among the Han nationality and some ethnic minorities. When sworn brothers, people kill a rooster, drop a few drops of chicken blood in each bowl of wine, swear to heaven, and then drink up the blood wine.

Starting from the "general purpose of chickens and prostitutes"
Recently, a dictionary added the meaning of "chicken" as another name of "prostitute", which caused an uproar. If there is opposition, it is said to be a lack of morality; Some people agree that they are advancing with the times and have the courage to face real life.
Seeing this argument, as an educator, I am also very interested and want to talk about some of my own ideas.
Chicken, why does it have such a different meaning? I didn't research some materials, but I guess the reasons are as follows: first, "chicken" and "prostitute" are homophonic; Second, in ancient times, due to the low status of women, there was a saying that "marry a chicken with a chicken and marry a dog with a dog". Originally, this woman would not have anything to do with chickens and dogs. The ancient books I read before said, "Ask for it when you get married, and marry when you are old." Judging from this sentence, it refers to the idea of single-mindedness, and of course there are despicable elements. Comparing prostitutes to chickens means that people are like chickens. Another popular saying in our area is that the word "chicken" is a bird and the word "duck" is a first-class bird, so prostitutes are called "chicken" and male prostitutes who eat soft rice are called "duck".
Of course, this has nothing to do with this article, and it is a casual discussion.
I also thought of a popular word among students some time ago: "Wow". Walking beside students, I often hear such words: "Wow, you are really amazing!" " ""Wow, you are so cool! When asked what "wow" meant, the students were at a loss and didn't know what it meant. Some people say that they learned it from the host population on TV, but the meaning is great anyway. I don't care much about such buzzwords, and I forget them after listening to them. But I was surprised when my wife mentioned the word "wow" the other day-it is said that the word "wow" is a dirty word, which originated in southern Fujian and means "I stuffed you".
It's a dirty word.
From this, I thought that some negative vulgar oral English spread very fast. In addition, quite a few people also relish this kind of communication and fun, which also encourages the proliferation of malicious spoken language.
The prevalence of chickens and prostitutes and the popularity of "wow" are inevitable and we can't stop them. However, I think it would be too cautious to write such a meaning into the dictionary. After all, most users of dictionaries are minors.
In the face of such a new term in the new period, how should teachers face it? I feel a heavy burden on our shoulders. The popularity of these malicious words is a serious violation of our mother tongue. In the real society, with the borderless development of information, the prevalence of virtual worlds and the increasing frequency of international exchanges, our traditional ethics are gradually being eroded and lost among the younger generation. If we don't strengthen the infiltration and edification of mother tongue, it may be alarmist and the consequences will be unimaginable. To gradually change this situation, it is necessary to form a good mother tongue learning atmosphere. On the one hand, schools should vigorously promote the study and practice of Putonghua; On the other hand, as teachers, we should strengthen the study and practice of mother tongue and strive to become promoters.
It is gratifying that in recent years, many schools have also appeared such a cultural tendency, consciously paying attention to the reading of traditional ancient poems, cultivating students' ability to interpret traditional culture, allowing them to gradually accept such edification and increase the accumulation of traditional culture. Our school is also preparing to carry out the activity of "three meals a day", that is, every morning, noon and evening, we will spare some time to recite ancient poems, read Chinese classics such as Saint Amethyst, and read classic American literature. These measures are of great practical significance for defending the dignity of traditional culture.

Anaidae is a general term for waterfowl, or real ducks. Small body, short neck and big mouth. Legs are behind your body (like swans), so you stumble. Unlike swans and geese, most real ducks (including several birds mistakenly called geese because of their individual size and body shape) shed their skins twice a year, and females lay more eggs in each nest, with smooth eggshells. The legs are covered with overlapping scales; The call and feathers show some gender differences. All real ducks, except duck and sea duck, are sexually mature in the first year, and they are paired in the breeding season, unlike swans and geese, which are paired for life.
According to different lifestyles, ducks can be divided into three categories: drilling ducks, diving ducks and perching ducks. Mallard duck (wild duck; The typical duckling is the ancestor of most domestic ducks and one of the most popular game birds. Habitat ducks, such as Moscow ducks, have long claws and are favorite arboreal ducks. Diving ducks include most marine species, such as eiderdown ducks and scoter. It also includes merganser (mostly like to live in fresh water areas, see merganser).

Duck yā waterfowl name. Separated from the wild, it has a flat mouth, a long neck, short feet and webbed toes, and is good at swimming. Wild ducks can fly. Usually refers to domestic ducks, which can't fly, but can be raised in groups, feeding on meat and eggs, and duck down as a quilt. There is already an artificial breeding ground ~
Duck is a general term for waterfowl of the family Anatidae, or real duck. Ducks are smaller, with short necks, and some genera have bigger mouths. The legs are behind the body, so the gait is unstable. Unlike swans and geese, most real ducks (including several birds mistakenly called geese because of their individual size and body shape) have the following characteristics: male birds shed their skins twice a year; Females lay more eggs in each nest and the eggshells are smooth; The legs of both sexes are covered with overlapping scales; The call and feathers show some gender differences. All real ducks, except the snub-nosed duck and the sea duck, are sexually mature in the first year and are paired in the breeding season, unlike swans and geese, which mature late and pair for life. According to the unique behavior of ducks, ducks can be divided into three categories: drilling ducks, diving ducks and perching ducks. The mallard duck is a typical duck and the ancestor of most domestic ducks. Habitat ducks, such as Moscow ducks, have long claws and are favorite arboreal ducks. Diving ducks include most marine species. The mallard flies from the south to the north to lay eggs in spring, and then flies to the south for winter in autumn. After they were domesticated by humans, they lost their frivolous migration. In order to get more duck eggs, they were not allowed to stop production and hatch. Over time, domestic ducks lose the ability to hatch eggs.
Types and characteristics of ducks
[Edit this paragraph]
Duck breeds are divided into meat type and egg type according to economic use.
Duck for meat is big and fat, muscular, delicious, gentle and slow. It grows fast in the early stage and is easy to fatten. Representative ones are Beijing Duck, Cherry Valley Duck, French Muscovy Duck and White Star Duck. At present, French Muscovy Duck and Australian White Star Duck, which are more suitable for the market, are favored. Their outstanding characteristics are good meat quality, high lean meat rate, low feed-meat ratio and strong disease resistance. For example, the meat of French muscovy ducks tastes like wild birds; Chest muscles and leg muscles account for 27-30% of the carcass; Under extensive conditions, the brooding rate and survival rate are as high as 95-98%.
Laying ducks are small, slender, with tight feathers, flexible movements, early sexual maturity, and lay more eggs, but the egg shape is small and the meat quality is slightly poor. The representative ones are Jinding Duck, Shaoxing Duck and Gaoyou Duck. Fujian Jinding Duck lays 260-300 eggs a year, with an egg weight of 60-80g, followed by Zhejiang Shaoxing Duck and Jiangsu Gaoyou Duck, with an egg production of about 250.
Breeding and crossbreeding of ducks
[Edit this paragraph]
(1) How to choose ducks?
The quality of breeding ducks directly affects the growth rate, physical size and laying performance of offspring. How to choose? The method is as follows:
1. Physical appearance is an important feature of a variety and the main basis of productivity. Therefore, the selected breeding duck must have the inherent characteristics of the breed, and at the same time, more attention should be paid to the choice of economic type.
(1) Selection of drake: big head, thick neck, deep and prominent chest, wide and long back, flat mouth, big and bright eyes, thick and powerful legs, strong physique, lively spirit, fast growth, tight feathers, luster and strong sexual desire.
(2) Selection of breeding ducks: In order to lay eggs, the selected ducks should be plump but not obese, with a long mouth, large and flexible eyes, slightly smaller head, long and slender neck, stout legs, wide spacing between legs, deep and wide chest, plump and drooping buttocks, wide and flat tail, steady walking, strong foraging ability, fine feathers and fine stripes. If the purpose is to produce meat, you should choose ducks with long body, wide back, deep and prominent chest, full feathers, slow movement, gentle temperament and fast growth.
2. Choose according to productivity
(1) egg production. The ability to lay eggs is related to the maturity, molting period and egg weight of ducks. Generally speaking, early onset date, late molting, large egg type and long laying duration will lead to high egg production, and vice versa.
(2) Meat production rate. Meat production performance is one of the important indexes of meat duck breeding, including body weight, growth rate, fattening ability and meat quality. Therefore, when selecting seeds, it is best to choose the fastest growing and heavier varieties in the same group, which meet the characteristics of this variety.
(3) Fertility. The fecundity of ducks usually refers to egg production, fertilization rate, hatching rate and duckling survival rate. Fertility is closely related to economic benefits. High fertility brings huge economic benefits, and vice versa.
Duck culture technology
[Edit this paragraph]
(1) Adaptive age of ducks:
The adaptive age of drakes varies with different breeds, generally 5-8 months old. During this period, the male duck is energetic and the female duck is fertile.
(2) Proportion of male and female ducks:
If the cross method is adopted, the combination method is generally adopted. But the ratio of male to female must be appropriate, too many drakes or too few drakes will affect the fertilization rate. The male-female ratio is roughly as follows:
Meat duck1:4-8; Dual-purpose duck1:8—12; Laying duck 1: 20-25.
(3) The service life of breeding ducks
Breeding ducks are usually replaced once every two to three years, because the egg production is the highest in the first year, and it drops 10- 15% in the second year and 15-25% in the third year. The egg production of ducks over three years is obviously reduced, the ducklings are stunted and the mortality rate is high. Therefore, the mother duck should be eliminated in the fourth year. The service life of meat ducks is shorter than that of eggs, and they will be eliminated in three years.
The breeding period of laying ducks is generally 2-3 years. Breeding drakes for meat are generally 1-2 years old.
How to identify the gender of ducks
[Edit this paragraph]
Laying ducks need female ducks, and keeping meat ducks separately is beneficial to management. Therefore, the sex identification of ducklings has certain economic value.
1. Shape recognition method
Generally, the head is big, the nostrils are narrow, and it is linear along the mouth nail, with a round body, and the tail tip is a male duck, while the head is small, the nostrils are roughly round, and the body is flat, and the tail is scattered by the female duck.
2. Sound tube identification method
The voice tube, also known as the lower larynx, is located at the top of the tracheal bifurcation. The male duck has an enlarged spherical tympanum with a diameter of 3-4 mm, which can be felt from the chest in vitro, while the female duck does not have such a sound tube.
3. Anal touch recognition method
Hold the newborn duck with your left hand, so that its back is facing the sky and its abdomen is facing down. Gently pinch the neck with your thumb and forefinger, gently lift the lower part of anus with your right thumb and forefinger, and press forward first. In the process of its retreat, if it feels something the size of hemp or rapeseed protruding, it is a male duckling, otherwise it is a female duckling.
4. Anal inversion identification method
Hold the newborn duckling with your left hand, hold the duck's neck with your middle finger and ring finger, with your head facing outwards and your abdomen facing upwards, and lie on your back. Then use the thumb and forefinger of the right hand to separate the feathers beside the anus to squeeze out meconium, and gently open the anus to make it evert. The male duck can see a protrusion (penis) about 4 mm long, while the female duck has no or only traces.
Hybrid utilization
[Edit this paragraph]
Economic hybridization can produce commercial ducks. For example, mule ducks produced by crossing male muscovy ducks with female ducks have obvious heterosis rate.
1. Duck nutrition and feed The basic nutritional elements of ducks are radiant energy, crude protein, crude fiber, calcium, phosphorus, multi-dimensional and trace elements, etc. Different production uses have different requirements on the quantity and quality of nutrients needed in the growth stage. The feed is mainly corn, soybean meal, fish meal and other raw materials. How to prepare and produce compound feed? First of all, consider the quality and quantity of raw materials.
Second, we should consider the price of raw materials, with the aim of making feed nutritious and affordable, that is, achieving high productivity and low production cost.
Because of the complexity of this technology, only one suitable method is introduced here for your reference.
2. Check feeding standard: Find out the corresponding varieties and the requirements of nutrient content in the feeding stage, such as Peking Duck 1-2 1 day stage, which can produce 2800 kcal/kg of energy, 2 1% crude protein, 3.5% crude fiber, 0.9% calcium, 0.6% phosphorus, etc. And record it. 3. According to the approximate proportion of raw materials in the diet, calculate the preliminary formula. The proportion of raw materials in the diet generally needs 40-60% of grains (corn, barley, etc.). ) (2-3 kinds); Wheat bran (wheat bran, rice bran, etc. ) feed10-20%; Plant protein raw materials (soybean meal, cottonseed cake, vegetable cake, etc. ) 10-20%; Animal protein feed (fish meal, etc. ) 3- 10%; Green juicy feed (green materials, etc.). ) 10-20%; 2-7% mineral feed (bone powder, shell powder, etc.). ); 0.3-0.5% of salt. When the ration of daily food is allowed, the formula is preliminarily discharged, the nutrient composition table of common feed is found, and the nutrient composition of the preliminary formula is calculated. 4. Compare the preliminary formula with feeding standard, and finally determine the feed formula. If an index is high or low, add or subtract the raw materials with low or high content of an index until they basically meet the standard. At this point, the formula has been completed. Pay attention to some indicators such as trace elements and vitamins. Generally, they are purchased with finished products, so there is no need to prepare them yourself. The technology prepared by yourself is more complicated, and improper preparation may cause problems. There are suitable feed purchases in the general market, so you can choose the best.
In addition, regarding feeding standard, the manufacturers who supply seedlings will generally provide them for reference. 5. Feeding and management of ducklings. Ducks are called ducklings from the time they are hatched to the age of 50 days, which are divided into ducklings and middle-aged ducks. The duckling period refers to the period from hatching to 2 1 day, which is the most critical period in the whole duck production. Because the newly hatched ducklings are still very weak, they can't regulate their body temperature, are sensitive to temperature, such as poor ventilation and heat preservation, and often have respiratory diseases (such as colds). Secondly, the digestive organs of ducklings are not well developed and their digestive ability is poor. If they are not careful in feeding, they are prone to intestinal diseases (such as enteritis). Therefore, the quality of brooding not only directly affects the survival rate and growth of ducklings, but also affects their future growth, fattening and laying eggs.
