What breed of chicken lays eggs that are highly nutritious

In terms of nutrients, if there is no pollution and simple feeding, the nutrients are not much different. On this basis, the nutritional value of eggs laid by free-range and grain-fed chickens is relatively high.

Free-range chickens have a healthy physique and high nutrition for laying eggs. Compared with fed chickens, because of the lack of sunlight, air circulation, and less space for movement, the nutritional value of the eggs laid by them cannot be compared with that of free-range breeding. A good constitution breeds healthy eggs.

Grain-fed chickens are more nutritionally complete than feed-fed chickens, so the eggs laid are nutritious and have a higher beneficial content than fed eggs. It also tastes better than fed eggs from fed chickens.

People usually call the eggs laid by free-range chickens in the natural environment of the farm house as native eggs, or firewood eggs; Stupid eggs. In fact, there is no obvious difference in the nutritional value of native eggs and ordinary eggs. Due to the different ways of feeding, the local chicken itself is indeed more comprehensive than the nutrition of the chicken in the chicken farm, but from the nutritional content of the egg, the protein, carbohydrate, cholesterol, calcium, zinc, copper, manganese in the native egg is higher than that of ordinary eggs, and the cholesterol content in the native egg is more than 2 times higher than that of ordinary eggs, which is related to the large proportion of its egg yolk; However, the fat, niacin, and selenium in native eggs are lower than those in ordinary eggs; It doesn't differ much in nutrients.

It can be seen that the nutritional value of native eggs and ordinary eggs has its own advantages. People can choose according to their preferences. Since the cholesterol content of native eggs is also high, for people who need to limit their cholesterol intake, they can usually use ordinary eggs.

Grass eggs and wild eggs are generally not artificially bred and have high nutritional value.

Hello dear, mountain eggs and native eggs are the best. Under normal circumstances, the two varieties of eggs, mountain eggs and native eggs, have relatively high nutritional value, belong to pure natural, pollution-free eggs, which contain more nutrients needed by the human body, and have certain benefits to the body after ingestion. There are many varieties of eggs, and the common varieties mainly include mountain eggs, native eggs and feed eggs, among which mountain eggs and native eggs have a higher nutritional value than feed eggs, which are mainly related to the growth mode of chickens and the nutrients in eggs.

Chickens that give birth to mountain eggs or native eggs are mainly free-range, mountain eggs are usually produced in hilly areas, chickens mainly feed on coarse grains, and chickens with raw eggs mainly feed on melons, fruits and vegetables.

Eggs, duck eggs, quail eggs, goose eggs, ostrich eggs are not much different in nutritional value, and the main nutrients contained in eggs are protein and fatty acids. The content of carbohydrates, cholesterol, calcium, zinc, copper, and manganese is relatively high, while the content of fat, vitamin A, vitamin B2, niacin, selenium, etc. is low, and there is little difference in other nutrients. In addition, it should be noted that some traders will artificially bred special breeds of laying hens, relatively small eggs are sold as native eggs, and the protein content of different eggs is very small, usually about 13 grams and 100 grams.

For example, eggs have the lowest protein content, about 12 grams and 100 grams, and goose eggs have the most protein, reaching about 14 grams and 100 grams. In other words, the difference in protein content is only about 10% at most. **。

But the yolk of all eggs has high cholesterol, so there is a certain amount of restrictions on eating eggs, and it is no problem for ordinary people to eat two to three a day, and people with three high or high cholesterol can properly adjust or not eat egg yolk. Vitamin A234 GRE, vitamin B1, vitamin B2, vitamin B3, vitamin, calcium 56mg, phosphorus 130mg, potassium 154mg, sodium, magnesium 10mg, iron, zinc, selenium and other important micronutrients, such as potassium, sodium, magnesium, phosphorus, especially the iron in egg yolk up to 7 mg 100 grams; Eggs are rich in phosphorus but relatively insufficient in calcium, so eating milk with eggs can be nutritionally complementary. Eggs are also rich in vitamins A and B.

Compared with the protein per 100 grams of red eggs, the protein per gram of white eggs, the protein per 100 grams of duck eggs, and the protein per 100 grams, if you want to supplement protein, you may wish to choose eggs.

In fact, the nutritional value of these eggs is very high, and I personally think that the nutritional value of quail eggs is higher, and the protein content contained in them is particularly high, as well as some trace elements of calcium and iron.

It is a native egg, and the nutrients of the native egg are relatively balanced, and this egg is fed from refined feed, so there is no *** to the body.

It is a native chicken, the nutritional value of eggs of local chicken is very high, and this egg is very delicious, I like to eat this egg very much.

I think the nutritional value of native eggs is relatively high, because this kind of egg is an organic food, and there are no additives, so the nutritional value is relatively high.

Native eggs. The nutritional value of this egg is particularly high, it can also supplement protein, can also improve immunity, can reduce cholesterol, and can also delay cell aging, playing a role in beauty.

The better breeds of laying hens are hemp feather high-yielding green-shell laying hens and black-feathered high-yielding green-shell laying hens.

Hemp feather high-yielding green-shell laying hens, as the name suggests, are hemp feathers, and the eggs laid are green-shelled. This kind of chicken is no different from ordinary chickens, but it produces more eggs than ordinary chickens. According to my personal breeding situation, it is not a problem for the chicken to produce an average of 250 eggs a year under free-range conditions.

Moreover, the green shell rate of its infiltrating eggshell is relatively high, which can reach about 55%.

The biggest difference between the black feather high-yielding green-shell laying hen and the hemp feather high-yielding green-shell laying hen is that it not only has a different feather color, but also the color of the chicken is completely different. The chicken of the high-yielding green tan shouting cherry shell laying hen is the same as that of ordinary native chickens, which is white. The skin, meat, and internal organs of the black feather high-yielding green-shell laying hens are all the same as the five black chickens, all black.

The rest

After the improved black feather high-yielding green shell laying hens, the egg production of the cluster can be better than the five black and green shell laying hens, and the annual egg production under free-range conditions can also reach about 250. However, compared with the five black and green shell laying hens, the green shell rate of black feather high-yielding green shell laying hens is significantly lower, because the green shell rate of purebred five black and green shell laying hens can reach about 80%.

In any case, under free-range conditions, the laying performance of hemp feather high-yielding green-shell laying hens and black-feathered high-yielding green-shell laying hens, and even purebred five-black-green shell laying hens, is better than that of the Highland series and Roman series of laying hens specially designed for cage breeding.
