1, the choice of native chicken varieties is undoubtedly domestic varieties, and China has a wide source, and there are local varieties everywhere.

2, the feed is very particular, grass chickens must eat grass, insects, miscellaneous grains and other "standard feed", eating compound feed is absolutely impossible. The breeder can't "spoon feed" it.

3. Grass chickens must be allowed to take the initiative to find food on the spacious farm grass. Air is the biggest factor affecting the quality of chicken. Chickens growing up in a depressed environment not only have a bad taste, but also have a bad influence on the human body.

The reason why chicken tastes like chicken is that it benefits from exercise. Because chicken muscles can fully grow and develop during exercise, intramuscular fat is rich, the proportion of aromatic substances in fat increases, and the taste is natural and fragrant.

As the saying goes, "No feast without chicken" shows that "chicken" plays an important role in people's diet. In recent years, people are tired of feeding less "chicken-flavored" chickens and keeping chickens in pens, and instead pursue chickens with good taste, rich game, high nutritional value and no pollution. There are also tricks to choose local chickens.

Pick chicken

1, the head should not be big.

2. Mao Liangyao

3, the feet should be thin

4. Small pores

Compared with the general feed "rapid prototyping chicken", the head of native chicken is smaller, the comb is smaller and the color is ruddy. Because most of the food eaten by native chickens is "pure natural" without any additives, the coat color of native chickens is brighter than that of ordinary "thoroughbred chickens", which will give people a feeling of shiny and shiny. Seeing "feet" is the most intuitive way to distinguish native chickens. Chicken's feet are thin, but they are strong and energetic. Because most native chickens are in a state of stocking and feeding for a long time, there will be a thick cocoon at the bottom of the palm. Feed chickens are fed for a short time, and the soles of their feet are naturally "delicate". In addition, the choice of native chicken depends on its pores. When picking, you can poke chicken feathers with your hand and see their roots. The primary chicken skin is thin and compact, with fine pores and a network arrangement. Imitation soil has thinner chicken skin and finer hair, but it is not as good as native chicken. Feed chickens, on the other hand, have thick skin and large pores. The most important characteristics of native chicken and imitation native chicken are yellow skin color and uniform distribution of subcutaneous fat, while the chicken skin color of feed is smooth and white. After cooking, the difference between chickens is more obvious. After the native chicken and the imitation native chicken are cooked, the soup is transparent and clear, and the soup noodles are caked with fat, and the fragrance is fragrant, while the feed chicken soup is turbid and the surface fat is less caked.

Free-range epidemic prevention

For a long time, low-level feeding and extensive feeding management have made native chickens have a characteristic, that is, less diseases and rough feeding tolerance. In addition, most chickens are kept in four gardens (orchard, mulberry garden, tea garden and bamboo garden), which is far from pollution and is conducive to disease prevention. However, due to the long feeding cycle and long-term grazing in the wild, the chance of exposure to pathogens increases, and sometimes pesticide poisoning caused by spraying pesticides on crops in the "Four Gardens" can not be ignored. In addition to strengthening daily management, such as strict disinfection and isolated feeding to eliminate some diseases, drug prevention is a good way.

chickenpox

Chickens were inoculated with fowlpox vaccine at the age of 15-35 and 90- 140 respectively. After 4-5 days, the scab on the thorn seedlings showed effectiveness, and the protection rate was generally 100%. Only by improving the feeding environment, strengthening nutrition and sterilizing feeding tools are the most effective methods to prevent parasitic diseases of native chickens.

Highly pathogenic avian influenza (HPAI)

Chickens are 20 days old 120 days old, laying eggs for half a year or entering the period of high influenza incidence. Half a year after the last inoculation, each chicken is injected with 0.5 ml of egg-reducing oil vaccine.

vaccination

Chickens of (1)7- 14 days old and 25-28 days old were given nasal drops and eye drops with clone 30 vaccine. At the same time, add 1 10,000 units of penicillin and streptomycin to every 500 chickens, or use Haitian, Haida, Bluestar and Pusha equally.

(2) At the age of 55-60 days, chickens were injected with Newcastle disease I vaccine and clone I vaccine at the ratio of 1: 1.5.

(3) At the age of125th, chickens were injected with new vaccine and influenza vaccine, each with 0.5 ml.

(4) At the age of 306 days, the cloned strain I muscle was injected repeatedly.

(5) Drinking water containing attenuated vaccine (vaccine II or IV) at the age of 440 days (before slaughter).

Marek's disease

(1) Chickens were injected with Marek's disease vaccine within 24 hours after hatching.

(2) Incubators, eggs and hatcheries are strictly disinfected; Nursery grounds and utensils have been strictly disinfected.

(3) Chickens imported from high-incidence areas should be vaccinated with Marek's disease for the second time.

(4) The breeders within1month should be isolated from each other.

(5) Once the disease occurs, the sick chickens should be eliminated immediately, and the threatened chickens should be disinfected with Anli 2000 to strengthen prevention.

Infectious bursal disease

(1) If breeder chickens have not been vaccinated with bursal disease vaccine before laying eggs or have not been vaccinated again after being vaccinated with oil seedlings for half a year, their offspring will be vaccinated with attenuated vaccine at the age of 5 days; Breeder chickens are inoculated with attenuated vaccine, and 0.2 ml oil seedlings are injected subcutaneously/chicken. 15 days old and 32 days old do not need epidemic prevention.

(2) If breeder chickens are vaccinated again after half a year, their offspring can be infused with attenuated vaccine at the age of 14 days. If breeder chickens are vaccinated with attenuated vaccine and 0.2 ml oil seedlings are injected subcutaneously, local chickens need not be vaccinated at the age of 24 days.

(3) In the outbreak area of bursal disease, chickens should drink water with high yolk immunity at 1 year old, and it is better to be immunized once at 5 years old, 15 years old and 32 years old.

(4) When commercial chickens are 1 day old, 7-day old, 14-day old and 2 1 day old, they can drink water with high egg yolk, so there is no need for epidemic prevention in the future.
