Freshly hatched chicks have lumps of meat on their bellies

Newly hatched chicks have lumps of meat on their bellies, which may be caused by infection of the chick in the late stages of incubation by pathogenic bacteria carried in the environment or in the eggs, usually in a mixed infection. This lump of meat may be umbilical corditis of the chicks, pathogenic bacteria that remain after hatching or invade the eggs during hatching. Umbilical corditis can lead to a weak constitution in chicks and an increase in death, with undead chickens gaining weight more slowly.

Common pathogenic bacteria are staphylococcal disease, colibacillosis, pseudomonas aeruginosa, etc.

Infect.

The chick that has just come out of the shell has a big belly, which is also called a big belly button or umbilical cord.

Inflammation is caused by infection of chicks in the late stage of incubation by pathogenic bacteria carried in the environment or in the egg, and is generally a mixed infection. Chicks hatch with a weak constitution and an increase in death, while undead chickens gain weight more slowly. Common ones are staphylococcal disease, E. coli disease, and Pseudomonas aeruginosa.

Infection. Staphylococcal infection of chicks with inflammation of the umbilical cord orifice, accompanied by foul odor, mortality.

high, oocyst on autopsy.

It is large, the yolk is blue-green or brown, and the umbilical cord site is filled with mucus under the skin. The mortality rate of chicks infected with Pseudomonas aeruginosa is high, generally concentrated in the first 7 days, the umbilicus is swollen by autopsy, and the dead chickens have yellow edema fluid under the skin of the head and neck (Marek's vaccine injection site), and the abdomen is green. E. coli-infected chicks do not eat, become paralyzed, and death gradually increases, the yolk is not absorbed on autopsy, and there is tofu-like exudate on the heart and intestines.

Summary. It depends on the size of the red meat and the age of the chicken. If this is a newborn chick, it may be difficult for it to survive without ** because it needs a lot of energy to adapt to the external environment and maintain body temperature.

If the red meat is large and has not yet caused an infection, then the chick may still have a chance to recover from it. However, it is best to take the chicks to a place with veterinary medical competence so that they can be examined and ** to improve their survival.

Can you add, I don't quite understand it.

Summary. Broilers will have chicks in their bellies because they are artificially bred, i.e., artificial insemination, and hens will hatch chicks after being inseminated.

The yolk sac of chickens is an embryonic membrane formed in the early stage, which begins to form on the 2nd day of hatching, and gradually expands to the surface of the yolk later, surrounding the yolk 1 3 on the 4th day, 1 2 on the 6th day, and almost covering the entire surface of the yolk on the 9th day. At the same time, the network of blood vessels on the yolk sac is distributed along the yolk sac to the entire yolk at the same rate. The yolk sac is connected to the fetus by the yolk sac stalk, and the yolk sac can secrete a digestive enzyme that turns the yolk into a soluble state, so that some thick yolk is liquid and absorbed by the cells of the yolk sac wall, and by letting the endothelial cells of the capillary cells of the yolk sac enter the bloodstream, so that the nutrients in the yolk can be absorbed and transported to the developing embryo.

The yolk sac has the function of exchanging gases with the outside world at the beginning of hatching, and is inhaled into the abdominal cavity together with the yolk before it emerges from the shell. In the whole incubation process, the egg yolk only plays a certain role in regulating the supply of imitation calcium, and most of the calcium required for embryonic development comes from the eggshell and egg barrier. However, the phosphorus of the embryo comes from the egg yolk, which plays a leading role in the supply of phosphorus.

During the 21-day incubation period of the egg, the protein content in the yolk was high and low, indicating that the embryo was not singular in utilizing the nutrients in the yolk, but was constantly changing.

Now that the epidemic is repeated, you must pay attention to safety when you go out, wear a mask when you go out, and wash your hands frequently! Have a great day, <>
