Is the nutritional content the same for regular chickens and stupid chickens?

The nutritional value of stupid eggs and ordinary eggs is almost the same, there is no obvious difference, and the nutrients contained in stupid eggs are also available in ordinary eggs. Stupid eggs are native eggs.

It is produced by free-range chickens in rural areas, and ordinary eggs are produced by caged chickens. Usually people think that stupid eggs have a higher nutritional value than ordinary eggs, but through the comparison of the nutritional content of these two eggs, it can be found that there is not much difference between the two eggs.

Free-range chickens are fed on insects, corn and other coarse grains.

For food, while caged chickens feed on concentrate feed, the amount of nutrients in the eggs produced will not be significantly different. Both types of eggs contain fats, vitamins.

Trace elements, amino acids.

and other nutrients and active ingredients, can supplement the needs of the human body, and the content is not much different.

Although the yolk of stupid eggs is slightly darker, it is mainly due to the fact that the insects eaten by hens contain chloranvin, and the nutrients are not significantly different from the yolk of ordinary eggs. In addition, stupid eggs have more flavor substances than ordinary eggs because they eat a richer variety of food, and the egg flavor is more obvious after being made into food.

From the above comparison, it can be found that stupid eggs are almost the same as ordinary eggs in terms of nutritional value, but the yolk is darker in color and more fragrant when made into food. If you only look at the nutritional value, there is no need to eat stupid eggs, and eating ordinary eggs can also achieve the same nutritional value.

Stupid chicken, that is, local chicken. Ordinary chickens, that is, feed chickens. The two chickens are raised differently, as well as the meat quality and nutritional value.

Local chicken: that is, local chickens, some are called grass chickens, firewood chickens, and stupid chickens. It refers to the domestication from ancient domestication, which has never undergone any hybridization and optimal breeding, and has been fed naturally or combined with rough feeding for a long time, and has strong foraging and survival ability in the wild.

It has the characteristics of resistance to rough feeding, strong nesting and disease resistance, and the meat is delicious.

The nutritional content of chicken is as follows:

1. Chicken has a high protein content, and it is easy to be absorbed and utilized by the human body, which has the effect of enhancing physical strength and strengthening the body. In addition, chicken contains ingredients such as fat, calcium, phosphorus, iron, magnesium, potassium, sodium, vitamins A, B1, B2, C, E, and niacin.

2. The content of potassium and sulfate amino acids in chicken is also very rich, so it can make up for the lack of beef and pork.

3. Chicken has more vitamin A content than other meats, and although it is worse than vegetables or liver in terms of quantity, it is much higher than beef and pork.

The effects and functions of chicken are as follows:

1. Chicken is flat, warm and sweet, and enters the spleen and stomach meridians; It can warm and invigorate qi, replenish essence and add essence; It is used for fatigue and thinness, lack of food, dizziness and palpitations, irregular menstruation, postpartum imitation of cryptolactus, thirst, edema, frequent urination, deafness and tinnitus, etc.

2. Chicken has a good therapeutic effect on malnutrition, cold intolerance, fatigue, menstrual irregularities, anemia, weakness, etc. Traditional Chinese medicine believes that chicken has the effects of warming and invigorating qi, replenishing deficiency and filling essence, strengthening the spleen and stomach, invigorating blood vessels, and strengthening muscles and bones.

3. Stir-fried cauliflower with chicken can enhance the detoxification function of the liver, improve immunity, and prevent colds and scurvy.

Black chicken is rich in melanin, protein, B vitamins and other 18 kinds of amino acids and 18 kinds of trace elements, of which niacin, vitamin E, phosphorus, iron, potassium, sodium content is higher than ordinary chicken, cholesterol and fat content is very low. The serum total protein and globulin contents of black chickens were significantly higher than those of ordinary chickens. The amino acid content of black chicken is higher than that of ordinary chicken, and the iron content is much higher than that of ordinary chicken, which is a tonic with high nutritional value. Therefore, black chicken is a good product to replenish fatigue and nourish the body.

Eating black chicken can improve physiological function, delay aging, and strengthen muscles and bones. It has obvious effects on the prevention and treatment of osteoporosis, rickets, and iron deficiency anemia in women. The "Compendium of Materia Medica" believes that the black-bone chicken has the function of replenishing weakness and labor, quenching thirst, benefiting mothers, and curing women's collapse and some deficiency diseases.

The protein content of Ben chicken is relatively high, there are many types, and the digestibility is high, which is easy to be absorbed and utilized by the human body, and has the effect of enhancing physical strength and strengthening the body. Chicken contains phospholipids that play an important role in human growth and development, and is one of the important ** fats and phospholipids in the dietary structure of Chinese. Chicken has a good therapeutic effect on malnutrition, cold intolerance, fatigue, menstrual irregularities, anemia, weakness, etc.

The medicine of the motherland believes that chicken has the effect of warming and invigorating qi, replenishing deficiency and filling essence, strengthening the spleen and stomach, invigorating blood and veins, and strengthening muscles and bones.

In order to ensure health and normal growth and development, chickens must constantly consume food (i.e. feed) from the outside world and absorb various nutrients from these foods, including water, protein, carbohydrates, fats, minerals and vitamins. After these nutrients enter the digestive tract, most of them are digested and absorbed, and some of them cannot be digested, absorbed and utilized, and they are excreted into feces and urine. Through feed analysis, it is known that the nutrients contained in chicken feed can be represented in Figure 3-2.

Figure 3-2 Nutrients in feed.

Eggs: Sweet and flat in nature, can calm the heart, calm the five organs, stop convulsions and safe the fetus. Vinegar boiled to treat red and white dysentery for a long time, postpartum dysentery; Cooked eggs are mixed with wine to treat postpartum tinnitus and deafness; Boiled egg yolk with vinegar alone is used to treat postpartum weakness.

Protein is one of the most important nutrients in poultry, is the material basis of life, it is an important component of the body, participates in most of the life-related biochemical reactions of animals, and plays an important role in animal life activities. The unit of protein is amino acids, and feed protein is composed of 22 kinds of amino acids, and amino acids form protein molecules with different forms through different permutations and combinations. Amino acids can be divided into two main categories according to whether they can be synthesized in chickens or how fast they can be synthesized:

One is essential amino acids and the other is non-essential amino acids. The essential amino acids of chickens include 13 kinds, among which methionine, lysine, threonine, tryptophan and isoleucine are less abundant in general feed, and the lack of them often affects the utilization rate of other amino acids, so these amino acids are also called limiting amino acids.

Chicken Ganping is warm, rich in nutrition, the protein content of chicken is as high as 1 3 or 1 times higher than that of pig, cow and goose, and the fat content is only , so eating chicken enhances physical fitness, and will not make people overly obese. Chicken benefits the five internal organs, replenishes weakness, strengthens muscles and bones, invigorates blood vessels, regulates menstruation, and stops leucorrhoea, which is the main ingredient in the best medicinal diet. Chicken liver, chicken heart, chicken intestines, chicken blood, and chicken brain can all be used in medicine, which can regulate the corresponding organs of the human body.

In particular, chicken gizzard contains a large amount of digestive substances and has a good effect of digestion and accumulation. The rooster is yang, and the complement is not as good as the hen; Hens belong to the yin, which is beneficial to the elderly, and old hens are mostly used with mothers. should be stir-fried with diced chicken, shredded chicken, and mixed with food.

1. Chai chicken, also called stupid chicken, hemp chicken. Chai chicken has the characteristics of tolerance to rough feeding, adaptability, foraging, stable genetic performance, strong nesting ability and strong disease resistance. The cost of raising Zen manuscript chai chicken is relatively low, which is very suitable for family farming.

2. The rooster is slaughtered in 5 months, and the average weight is about catty, and the hen is about catty; Sexual maturity is 5 months, and production begins at 5 months; The annual egg production is 150 180 pieces, the average egg weight is 40 He Zhuxiao 45 grams, and the eggshell color is mostly white and light brown; Its egg yolk ratio is large and the color is yellow, the egg white is viscous, the yolk membrane is thick, and the color is bright.

Although eggs are produced by domestic chickens, the basic ingredients are familiar proteins, fats, vitamins, minerals, etc. But are eggs really the same?

This is difficult to convince, at least, intuitively, there is a noticeable difference in the color and size of the eggshells.

Of course, you can say that this is just a difference in appearance and size, but many people reflect that the flavor of eggs is different, so in this case, is it really just a psychological effect?

The answer is: no.

The flavor of eggs is really different.

Second, different eggs are really different.

Many people feel that the flavor of eggs is different, and it is not their illusion that different eggs show obvious flavor differences.

In fact, what we call flavor is essentially the feeling that a flavorful substance is received and formed by our taste receptors.

And the flavor substances of eggs have long been cracked. As early as 1975, Macleod et al. used professional equipment to make a comprehensive analysis of volatile components in eggs [1].

Egg flavor substance detection device, source [1])).

Eventually, 65 of these compounds were found to be related to the flavor of the eggs. These include C7 and C17 saturated linear aliphatic hydrocarbons, unsaturated linear aliphatic hydrocarbons, aromatic compounds, and small amounts of aldehydes and ketones.

Egg flavor substance, the figure is too long, the truncated part, source [1])

Further comparison of eggs with different ** such as free-range chickens, caged chickens, eggshell colors, and different storage times showed obvious differences in the volatile composition of these eggs [2].

Differences in flavor substances of different eggs, the figure is too long, and the truncated part is taken from the source[2])).

Other studies have further expanded the study of egg flavor substances, and more flavor substances have been discovered, and it has been found that the flavor substances in eggs can be generally divided into alcohols, aliphatic hydrocarbons, aldehydes, ketones, aromatics, furans, sulfides, terpenes, etc. Moreover, there are significant differences between different eggs [3].

Therefore, everyone thinks that the flavor of different eggs is different, not because of the psychological effect, but because it is indeed different.

Of course, some people may ask, even if the flavor is different, the overall nutrition of eggs should be the same, right? The answer is still no!

3. Different eggs have different nutritional content.

Eggs are a product of chickens, and different chickens ingest different foods will eventually affect the nutritional content of eggs. Minerals such as phosphorus, calcium, and vitamins in food will directly affect the nutrition of eggs, and pigments will also affect the nutrition of eggs, not to mention the basic food nutrients.

For example, when mulberry powder (a mixture of branches and leaves) was added to the diet of eggs, the egg production rate of eggs was changed [4].

Source: [4]).

There are also differences in egg-related ingredients, especially the color of the yolk.

Source: [4]).

It can be seen that the nutritional content of eggs can be well changed by adjusting the food, which is why different people have different nutritional identities for eggs with different feeding methods.

That is, we often call native eggs and ordinary eggs.

Whether there is a difference in nutrients between native eggs and ordinary eggs has always been the focus of concern of the majority of foodies, although folklore says that native eggs are more nutritious than ordinary eggs, it is an indisputable fact that there is a big difference between them. But from the nutrition expert test results show that the nutrients of native eggs and ordinary eggs are not much different, ordinary chickens due to the feed formula science, nutrient supplement balance, so ordinary chickens produce eggs are generally larger, containing nutrients (protein, trace elements, etc.) is not worse than native eggs. On the contrary, free-range chickens are relatively small in size because of unbalanced nutrition, and eggs are easy to be contaminated due to poor growth environment.

However, in the free-range state, local chickens eat more green leafy vegetables, and the content of carotenoids and vitamin B2 in the egg yolk is high, so the egg yolk is larger and darker in color (Table).

It should be pointed out that the breed and growth environment of chickens are different, as well as the influence of many factors such as the body quality and age of hens, the quality of eggs of different types and individuals will be quite different, and this difference does not represent the quality of eggs, and different consumers' preferences for egg size will also be different. Therefore, there is no conclusion on the judgment of who is superior and which is inferior between native eggs and ordinary eggs, and the eggs produced by chickens grown in different environments may have differences in taste, which is completely judged by each person's feelings.
