How big is the local chicken, and whether the gizzard of the local chicken is big or small

Due to the large number of local chicken species, different body size and production performance, there is no complete data on nutritional requirements. Generally, the age of local chickens is 13 to 16 weeks, but white broilers only need 6-8 weeks. Due to the long growth period of local chickens, the nutrient concentration of energy and protein in the diet can be lower than that of white broilers.

When formulating the feed formula, it is necessary to consider: the nutritional requirements of native chickens; the nutritional content of feed raw materials; Feed**and**; Characteristics of feed raw materials. Generally, trace minerals and vitamins can be purchased from commercial mineral and vitamin premix, so the focus of calculating the feed formula is energy, protein, amino acids, salt, calcium and phosphorus, and the salt is quantitatively added about % Therefore, the research data on the nutritional requirements of local chickens are also based on essential amino acids composed of energy, protein and protein, as well as calcium and phosphorus.

In the general practical chicken diet, sulfur-containing amino acids are easily deficient, so methionine should be supplemented. According to its growth stage, native chickens are divided into brooding period, growth period and fattening period, and the nutritional requirements of native chickens vary according to their growth stage.

1.The brooding diet needs to contain metabolic energy megajoules, protein 22%, 23%, calcium, available phosphorus, sulfur-containing amino acids, lysine and tryptophan.

2.The diet during the growth period needs to contain megajoules of metabolic energy, 17% 20% protein, sulfur amino acids, % calcium, and available phosphorus.

3.During the fattening period, the feed should contain 17% of metabolic energy megajoules, 17% of protein, and 0% of sulfur amino acids56 %, calcium % available phosphorus.

The gizzards of native chickens are small, because native chickens are naturally raised and are not fed hormones, so they are smaller than those that grow up with hormones.

However, it is not absolute, many local chickens are simply fed corn in the later period of Chalaoyuan. Such chickens have single nutrition, ugly coat color, and cannot meet the growth needs at all. At present, the feeding method of local chickens is generally feed with grain feeding, some are fed with full-price pellets, and some are fed with concentrate, or premix.

Therefore, if you are simply fed with full-price pellets, the gizzard of the chicken is generally smaller, but if you have been fed corn and other foods, the gizzard of the chicken is relatively large, and the gizzard is constantly exercised, and it will be thicker.

The concept of "native chicken".

Many consumers are struggling with the concept of "local chicken". The concept of native chicken is very vague, and the definition of native chicken is different in each place. In some areas, the long breeding cycle becomes a native chicken; In some areas, chickens that can eat corn are called local chickens.

In some areas, weight is the standard, 5 catties are called local chickens in a defeated state, and those weighing more than 5 catties become broilers; In some areas, the color of the feet is used as a distinction, and the yellow-footed ones are broilers, and the black-footed ones are native chickens. There are many other ways to distinguish between Hanshouran, which leads to a very chaotic local chicken market and makes it unclear for consumers to distinguish.

First of all, the local chicken slaughter time is long, at least 8 months or more, roosters and hens are the same, generally are fed about 11 months to slaughter, 2-3 months of each year to hatch chickens, to the New Year, is the most suitable. If raised.

Kill it in two or three months, although the nutrition is good, but if you don't deal with it well, there will be a fishy and tender taste. The stew and stir-fry should not be too long, because the chicken is too tender, and if the stew is too long, it will become chicken soup and have no meat texture. Or raise 10 to 12 months of adult chicken, the meat will be a little older, the bones are not bitten, the chicken is very elastic, need to be simmered for a longer time, or make soup.

Therefore, the chickens that have just reached adulthood at 8 months are the most delicious. In addition, most of the native chicken farmers will raise small roosters for about half a year, leaving hens to lay eggs.

It is also very expensive) after two years the egg production drops significantly, at this time the ** old hen. It's economical and delicious.

Secondly, the slaughter time of local chickens has a lot to do with the size and size of the chickens. Under normal circumstances, small broiler roosters are generally raised for 100 days and hens are raised for 120 days; Medium-sized broiler roosters are generally raised for 110 days and hens are raised for 130 days. Moreover, the breeding environment will also affect the length of time that native chickens are raised

It's like a stupid chicken in the house.

The cycle is the shortest, it is not good at exercise, it consumes more energy, matures quickly, and can be about 90-100 days; The maturity period of free-range chickens in orchards is slower, and the chickens are generally about 120-180 days. What needs to be reminded here is: under normal circumstances, many people's choice is to go directly to the market after reaching the head, because one more day of feeding, there will be some fixed costs, for breeders, the shorter the cycle, the better.

Nowadays, there are few real chickens even in rural areas, many families no longer grow land, and the grain is not so abundant, and most of them are fodder to grow. If you want to eat authentic local chicken, you have to find the right person. Generally, the maximum age limit of breeding, I think it is 8 months, however, just to mature chickens, are very delicious, just look at how you like to eat chicken, because there are too many chicken practices, everyone's taste is different, just choose the kind of practice you like.

How long is the best way to raise local chickens? According to the author's experience in rural life, the local chickens raised in the countryside should be at least 6 months old before the chicken is the best.

Most of the chickens we eat today are broiler chickens in farms, and they are generally slaughtered in about forty or fifty daysThis kind of chicken has a short growth time, the meat is relatively tender, but the flavor is much less, especially the chicken bones, the taste of the meat is relatively light, and the time for stir-frying and stewing is also relatively short, and it is quickly cooked after being put into the pot. These are the characteristics of the "fast chicken".

The local chicken in the countryside is different, although it is more time-consuming and laborious to make, but it tastes very fragrantThis meaty flavor is unmatched by other chickens. If you choose a large wood stove in the countryside when cooking, the taste is simply incomparable, the meat is fragrant and beautiful, and it is truly delicious in the world. Every time I return to my hometown in the countryside during the Chinese New Year, my mother will "prepare" an old hen that has been raised for a year, stew it on the big wood stove for half a day, and at night the family sits together and serves a pot of steaming and fragrant chicken soup.

Although I have been away from the countryside for many years, I have never forgotten the customs of the countrysideI remember when I was a child, I raised a lot of chickens at home, and in the summer, I would go with my children to catch grasshoppers in the grass with a small bottle, or catch dragonflies to taste the chicks, although there are a lot of chickens, but I only like a Luhua chicken, maybe because of its unique appearance, every time I catch a grasshopper and other small insects, I will feed this Luhua chicken separately, so that later, I obviously became a chicken mother, no matter where I go, this little Luhua chicken will follow me, and I can't get rid of it.

I can't remember what happened later, I just remember that this was a little hen, as for how many eggs were laid later, and where did this cute Luhua chicken go in the end? There is not the slightest impression left. I once asked my mother, maybe my mother is old, maybe she has too many chickens, in short, she has no impression of the Luhua chicken I said.

As a rural kid, I love any little animalIncluding these local chickens who don't look good, walk with a limp, and defecate everywhere. After leaving the countryside, I still have a love for the small animals at home, I remember one year my mother raised a lot of red roosters, there are more than ten of them, every time I go home, I will sit in front of the chicken coop and observe them quietly, although the appearance seems to be the same, if you look closely, each chicken has its own characteristics. Among the red roosters that year, the last one left was still the one I chose, and it was a guy with full combat effectiveness.

Now I have left the countryside, but I still love the small animals in my hometown, my mother is old, but I still raise a few chickens and ducks and other small animals every year, but the number is far less than before, despite this, every New Year, I will eat a big rooster raised by my mother, with a strong hometown flavor, such a chicken is the most delicious, the most flavorful.

For three months, the local chickens raised by themselves or those raised in the countryside are almost the same. The chicken farms are all an assembly line integrated feeding feed quickly, which will definitely be a little inferior to the local chickens.

I think I bought back chicks to raise at the beginning, to raise about a chicken about two catties, about four or five months, this time the meat of the chicken is very tender, the taste is also very good, and the nutrition is very rich.

About 6 and a half months - about 1 year old chicken is the best to eat, too small organs are not fully developed and the muscles are not sound, and carry some viruses have not been eliminated, too big meat is old and difficult to eat, and the mouth and claws have chicken poison.

It is best to raise more than eight months of local chicken, and the local chicken over eight months will be very firm, and it tastes particularly fragrant, my father raised more than a dozen, and every time I go back to Dad's stewed chicken, I always can't help drooling.

In general, local chickens raised for 6 to 8 months are particularly delicious, because the 6 to 8 month old chicken is very tender and delicious, and it is best for frying.

Adult chickens are more delicious, about 8-10 months, at this time the chicken is firmer and the soup is more delicious.

Loose hens before laying eggs, or roosters before crowing, are used for white chopping chickens

Authentic local chickens are free-range chickens from previous farmers, and generally have the following characteristics:

1. The growth cycle of the local chicken is relatively long, generally speaking, a local chicken from hatching to can be slaughtered and eaten meat, the time required is more than six months, and even in this time period, the meat quality of the local chicken is still very tender, more suitable for stir-frying, to be used to cook soup, the local chicken needs at least 10 months of feeding time.

2. The chicken foot stem of the local chicken is relatively slender. Generally speaking, due to the reason of the breeding method and the breed factors, the chicken feet are slender, and most of the breeding methods of the local chicken are free-range, and most of the food eaten is corn kernels and food found in the soil, due to these reasons, the chicken feet of the local chicken are slender and sharp.

3. The weight of local chickens is limited. Due to the breed and living habits, the local chicken is generally not long, most of the local chicken in the breeding of about 10 months, that is, more than 3 catties, if you insist on raising, 2 years of native chickens are between 4 and 5 catties, this is determined by the characteristics of the native chicken, of course, if you feed it concentrated feed, will it be more fat, this has not been tried.

5. Most of the local chickens circulating in the market are not purebred native chickens, and most of the breeding methods are mainly captive-raised. Now most of the local chicken seedlings on the market are hybrid chicken seedlings hatched from the chicken farm, this kind of chicken seedlings and maintain the appearance of the chicken and the long meat advantage of broilers, most of them can be slaughtered through feed breeding for more than 5 months, and a chicken can grow to about 5 catties, ** in the countryside will be cheaper, in the city, it is sold as a local chicken, so that large farmers can ensure their income.

<>1. The weight of the native chicken: the weight of the adult is generally about 2kg, and the hen is generally about it, which is related to the breed of the native chicken and the breeding technology and management methods of the farmers. 2. The difference between native chickens and feed chickens:

The head of the native chicken is smaller than that of the feed chicken, the mouth is in the shape of an olecranon, the comb is larger, the blood color is full, the claws are small and the tip is long, the claws have a very thick cuticle, the meat color is more yellow than the feed chicken, the meat is more compact, and it is elastic; The mouth of the feed chicken tends to cut off the beak hook, the comb is smaller, the blood is darker, the claws are more fat, there is no thick cuticle, and the meat is looser.

1. How many catties of local chickens are generally

1. The weight of adult roosters is generally about 2kg, and the hens are generally around, which is related to the breed of local chickens, such as Yifeng native chickens, adult roosters weigh about much, and adult hens weigh about about. Of course, the weight of local chickens is also related to the breeding technology and management methods of farmers.

2. Even in the case of sufficient food supply, local chickens will limit their size due to their own breeds, and their weight will not increase after reaching the limit of growth. Its body is generally small and delicate, with a delicate appearance, strong chest and leg muscles, a small head, short legs and thin feet.

Second, the difference between native chickens and feed chickens

1. The difference between chicken head and chicken mouth.

The head of the local chicken is smaller than that of the feed chicken, and the mouth is in the shape of an eagle's beak, which is caused by self-foraging; Whereas, feed chickens tend to cut off their beak hooks, so they look milder to people.

2. The difference between cockscombs.

The comb of the native chicken is larger, the blood color is full, and the color is bright; On the other hand, the comb of feed chickens is smaller, and the blood color is darker.

3. The difference between chicken feet.

The claws of the native chicken are small and long, and there is a very thick cuticle on the claws, which is more seriously worn because it often grabs things; The feed chickens are often raised in cages, the claws are relatively thick, there is no thick cuticle, and the claws basically have no traces of wear, and they are more artificially modified.

4. The difference between chicken skin.

The color of the skin of native chickens is more yellow than that of feed chickens; Due to the short growth cycle of feed chickens, the pores on the skin of chickens are larger than those of native chickens.

5. Difference in meat quality.

The meat quality of the local chicken is firmer than that of the feed chicken, and it is elastic, the muscle fiber is fine, and it tastes chewy, and it takes a long time for the traditional local chicken to be stewed; The meat quality of the feed chicken is relatively loose, the muscle fibers are thick, easy to break, and can be stewed in a short time.
