The daily inspection of a large-scale farm is a very important task. By inspecting the state of the flock, abnormal conditions can be discovered in time, and problems and problems can be found as early as possible to avoid losses.
A general observation
Pay attention to the chicken's response to the outside world, food, drinking status and actions. Healthy chickens are sensitive to hearing, have a quick response and have a strong appetite. If there is an unhappy event, a listlessness, an unsteady gait, feathery fluffyness, and snoring or lying, it indicates that the chicken has an abnormality.
The observation of the second cocks and meat
The color of the healthy chicken crown is bright red, plump, and the tissue is soft and smooth. Meat pods are symmetrical, full and bright red. The change in the color of the quilt is a sign of a morbid state, usually with the following changes.
1 crown white
Common in a variety of anemia diseases, such as severe parasite infestation (such as chickens living from Cytoplasmosis), Marek's disease and so on.
2 crown hairpins
Common in hot diseases such as bird flu, Newcastle disease, fowl cholera and so on.
Crown atrophy
Commonly seen in chronic diseases, the crown of the newly opened cocks suddenly becomes atrophic to leukemia.
4 chicken pox
Crown blisters, puss, and scabs are characteristic of fowlpox.
Three observations
Check the appearance of the eye, whether the eyes shed tears, whether the cornea is clear, whether there are secretions and ulcers, and whether there is cheese-like material in the conjunctiva. In the absence of vitamin A, milky discharges are found in the eyes of affected chickens, and the upper and lower eyelids often adhere together. The corneal opacity is unclear, and Marek’s disease may have the phenomenon of disappearance of iris pigments.
Four examinations of respiratory conditions
Pay attention to the frequency of breathing, the number of normal breathing hens 20 to 30 times / minute. Observe the chicken as quietly as possible, such as breathing during open mouth. There are no abnormal sounds, such as cough, sneezing, rales, and nasal secretions. Newcastle disease, infectious bronchitis, diphtheria-associated chickenpox, and mycoplasma gonorrhoeae are the diseases that present the respiratory tract as the main symptoms. When a Newcastle disease occurs, chickens often make a "gurgling noise" and mouth flow.
Five observations of eating and drinking
During the production period, the daily intake and drinking water are basically the same. If there is a sudden decrease in feed intake and an increase in drinking water, it indicates that the chickens are abnormal.
Six stool inspections
Examine the color, status, odor of the excrement, the degree of digestion of the food, etc. Abnormal changes in the excrement are often signs of the disease.
1 white stool
Mostly caused by nutrient or infectious factors caused by renal operations caused by urate excretion disorders. Such as renal bronchitis, infectious bursal disease, discharge lime-like stool.
2 green stool
Mostly due to high fever caused by loss of appetite, there is no food in the intestine to neutralize, decompose the green bile from the liver, so that the bile with the secretions excreted together with the body, the emergence of green feces; more common in Newcastle disease, bird flu and other viral diseases .
3 red stool
It is mainly caused by inflammation of the intestinal tract or fecal occult blood. If the feces is purple, more suggestive of coccidiosis; if the stool is bright red, more suggestive cloacal injury, bleeding.
The observation of seven eggs
Under normal production conditions, the egg surface is clean and smooth, the eggshell is sturdy and complete, the color is balanced and stable, the size of the body is the same, the heavy feeling in the hand is good, the sound of collision is crisp and it is not easy to break, there is no foreign matter in the eggshell after opening. The egg yolk is full and full, and the protein is thick and thin. Occurrences of egg shells, wrinkles, malformations, and even broken eggs may result in malnutrition (such as insufficient calcium or phosphorus or inappropriate proportions), metabolic disorders (vD deficiency or lack of light), and environmental stress (such as high temperatures, Problems such as poisonous substances in feed, etc., disease problems (such as Newcastle disease, infection} gas bronchitis, etc.), poor management, etc., resulting in the occurrence and increase of abnormal eggs.
