Observing feces

Observing feces

Because of the special physiological structure of poultry, the excrement of urine and feces produced by poultry is excreted from the cloaca. Under normal circumstances, chicken manure is cylindrical, thin and curved, with white urate on the surface. When the feces change, it is often a sign of some diseases. The techniques for identifying chicken diseases from changes in chicken manure are described below.

First, white dilute feces

More due to intestinal mucosal secretion of a large number of intestinal fluid and urate increased. Nutrient factors or infectious diseases that cause kidney damage can all lead to uric acid excretion disorders, resulting in increased urate, resulting in chickens row white dilute feces.

1. The chicks are white. The peak period of onset was 7-14 days old. The sick chickens were depressed, chilly, trembling, hairy pines, fins, appetite and thirst. The most typical symptom is pulling a white paste like thick milky feces.

2. Infectious bursal disease. Chickens 3 to 6 weeks old are the most susceptible, and chickens are chilly, shrinking, white, sticky and watery. An autopsy revealed bleeding in the leg and chest muscles, edema and hemorrhage in the bursa of Fabricius, and a sliver of bleeding at the junction of the stomach and muscle.

3. Fowl cholera. It usually occurs in adult chickens. Diarrhea often occurs in diseased chickens. An autopsy revealed epicardial and coronal fat-filled hemorrhages. The pericardium contained a small amount of fluid. The surface of the liver was scattered with many grey-white necrotic spots and intestinal bleeding was significant.

4. Chicken colibacillosis. A few days after hatching, the susceptible chickens will die in large numbers. Chronic people will have diarrhea, feces will be gray, and there will be convulsions and circling movements before death. The zygomatic examination revealed yolk enlargement, and the necropsy of older chicks showed white exudation of white cellulose on the liver and heart.

Second, the green dilute feces

At the end of serious illness, due to the loss of appetite, there is no content in the intestine, inflammation of the intestinal mucosa, speeding of peristalsis, increased secretion of mucous membranes, green bile or intestinal fluid mixture.

1. Low pathogenic bird flu. The susceptible chickens pulled white and green dilute feces with obvious respiratory symptoms. The necropsy showed redness of the trachea, purpura, bleeding of the glandular stomach nipples, diffuse bleeding of the intestine, and congestion and bleeding of the ovary of laying hens.

2. Respiratory infectious bronchitis. Affected chickens have mucus when they cough, and chickens stretch their mouths to breathe. The necropsy shows that there is a serous, catarrhal or caseous exudate in the larynx and tracheal mucosa.

3. Acute typhoid fever. The diseased chicken pulls green or white feces, and the chicken is reluctant to move, showing an erect penguin-like posture. Hepatectomy was purple in necropsy.

Three, brown red or dark brown dilute feces

Mainly seen in intestinal bleeding disorders. Posterior haemorrhage of the intestine was reddish brown and mainly found in cecum. Intestinal bleeding was fecal dark brown, common in young chicken intestinal coccidiosis or some acute infectious diseases and chronic poisoning.

POCT Analyzer

The characteristics of POCT devices determine that they can play an important role in primary medical institutions. In order to standardize and strengthen the application of on-site rapid testing in primary medical and health institutions, promote the rational allocation, safe and effective use of POCT in primary medical and health institutions, give full play to its use value, and ensure the healthy development of medical and health services, "On-site Point-of-care Testing (POCT) Primary The Expert Consensus on the Application of Medical and Health Institutions (hereinafter referred to as the "Consensus") came into being. The consensus was published in the 2019 "China Medical Equipment" magazine after first draft writing, 2 expert on-site discussions, 2 expert online review meetings, and 3 submission revisions. The formulation of the consensus will greatly promote the management standards of the POCT industry, continuously increase the training of grass-roots personnel, deeply understand the application requirements of POCT at the grass-roots level, and promote the rapid development of the POCT industry.
Point-of-care testing (POCT) represents a fruitful method in today's hospitals in terms of patient care and cost management. Its application enables some of the testing items originally undertaken by the central laboratory to be transferred to the clinical departments and patient beds that need it. side. For blood gas analysis technology, POCT has shown great advantages.

Our blood gas analyzer is small and portable, beautiful in appearance, accurate in results and good in stability. It is a blood gas analysis platform with both appearance and strength. It can be used not only in the central laboratory department, but also at the bedside of patients to meet the bedside detection needs of clinical departments such as hospital ICU, emergency, anesthesia, respiratory, neurology, etc. It realizes true POCT blood gas analysis and provides more advantageous assistance for clinical practice.
