Iron is an essential trace element for the growth and development of suckling piglets and is part of many enzymes in the body. Iron stores in young piglets are minimal, requiring 7 mg of iron per day, and up to 1 mg of iron per day in breast milk. Therefore, the iron stored in the piglets will be depleted soon, and anemia may occur if it is not replenished promptly. Iron selection time The reason why newborn piglets are prone to iron deficiency anemia is due to insufficient iron storage in newborn piglets. According to the study, the newborn piglets have iron stores of 40 mg to 50 mg at birth. The growing piglets need about 7 mg to 16 mg of iron per day to ensure their rapid growth. The only source of iron for newborn piglets is obtained from breast milk, and each newborn piglet can only obtain approximately 1 mg of iron per day through breast milk. Therefore, the iron storage in newborn piglets is only enough to maintain the body's demand for 3 days. To ensure that iron deficiency anemia does not occur after 3 days, iron supplementation should be carried out on newborn pigs within 4 days of age, otherwise iron deficiency anaemia will occur, causing piglets to suffer from lack of energy, loss of appetite, diarrhea, slow growth, and even growth. Fast piglets will suddenly die due to lack of oxygen. The choice of iron supplements Strictly control the quality of farms (households) carefully when selecting iron supplements. The first thing to do is to select the products produced by GMP-certified and listed companies. In addition, check the production date, validity period, and packaging to prevent unnecessarily or expired products from causing unnecessary losses. Specification selection of iron supplements currently used is more iron is dextran injection, specifications are 50 mg per milliliter, 100 milligrams per milliliter, 150 milligrams per milliliter, Zhengbang Dongbao production "rich blood Wang" iron supplement preparation specifications for each milliliter 150 mg, high dextran iron content, and a better production process, making the pharmaceutical solution particles smaller, less irritating to piglets, fast absorption, extraction and injection is very convenient. In addition, the addition of selenium, cobalt, and vitamin B, etc., can be supplemented by more needles, and has a fuller effect, which is more conducive to the comprehensive absorption of iron, and can also promote the further improvement of the body's hematopoietic function, and increase the iron element in the hematopoietic process. The utilization rate. The storage of iron agents All manufacturers of iron packaging bottles are brown glass ampoules, because dextran iron sees easily decomposed into dextran leading to body allergies and extremely toxic trivalent iron ions, so when storing iron preparations, they should be stored in Cool and ventilated place, the best conditions are best stored in the refrigerator, refrigerated, prohibited post-injection exposure to sunlight. Determination of iron dose The iron supplement dose of neonatal piglets is in the range of 150 mg to 200 mg per milliliter. A small amount can not meet the body's demand, and a large amount of iron can easily produce strong side effects. It has been reported that overdosing of iron supplements can cause iron overload. Many important organs such as lymph nodes, spleen, liver, lungs, and kidneys are damaged, weakening the body's immune function and physiological dysfunction, and being prone to bacterial and viral infections. disease. The clinical manifestations include hemorrhagic gastroenteritis, diarrhea, vomiting, shock and acute liver necrosis in piglets. In the actual operation process, if the iron supplement preparation of 50 mg to 100 mg per milliliter is selected, 2 ml to 3 ml will be injected. Since the weight of the pig is small, the injection site can easily be packaged after the injection, and the absorption is not Good, can not reach the injection effect. When the iron preparation containing 150 mg/ml of iron is selected, only 1 ml of injection is needed, the injection dose is small, the injection is easy, and the absorption is rapid and complete.

The COVID-19 Antigen Test Cassette is immunoassay based on qualitative membrane strip for the detection of COVID-19 antigen in anterior nasal swab
specimen. In this test procedure, anti-COVID-19-N antibody is immobilized in the test line region of the device. After an anterior nasal swab specimen is placed
in the specimen well, it reacts with anti-COVID-19-N antibody coated particles that have been applied to the specimen pad. This mixture migrates chromatographically along the length of the test strip and interacts with the immobilized anti-COVID-19 antibody. If the specimen contains COVID-19 antigen, a colored line will appear in the test line region, indicating a positive result. If the specimen does not contain COVID-19 antigen, a colored line will not appear in this region, indicating a negative result.To serve as a procedural control, a colored line will always appear in the control line region, indicating that proper volume of specimen has been added and membrane wicking has occurred.
