Pig farmers always encounter various problems in the process of raising pigs. Especially the development of large-scale breeding industry now brings different elements to the feed elements. Today, Hui Nongwang Xiaobian wants to introduce to you. How to do piglet anemia and the correct method of piglet iron supplementation! Nutritional Characteristics of Trace Element Iron and Its Effect on Growth Performance of Pigs 1. Nutritional properties of iron 1.1 The presence of iron in animals The vast majority of iron in animals is mainly in the form of organic compounds, of which there are few inorganic iron ions. The importance of iron on pig growth 1.2 The main physiological function of iron The main physiological function of iron is to transport carbon dioxide and oxygen through hemoglobin and to protect and store oxygen through myoglobin. Although there is very little iron in animals, it has a great effect, and it can handle a combination of various compounds in the process of oxidizing energy. 2. The effect of iron on pig performance 1.1 Iron can prevent anemia in piglets. 1.2 Iron can improve the growth performance of pigs. 1.3 Iron can improve the reproductive performance of sows. 1.4 Iron can make the pig's skin red and shiny, showing a healthy color. Introduction to piglet anemia and symptom analysis Pig iron deficiency, also known as piglet anemia, refers to a nutritional anemia that occurs in 15-30 day old suckling piglets. The main reason is iron deficiency. Some piglets have anemia that is not only iron-deficient but also lacks copper. In the absence of iron, the amount of red protein decreases, and when copper is deficient, the number of red blood cells decreases. If the piglets are injected with 100-150 mg of iron at 2-3 days old and 10 days old, it can effectively avoid the disease. What are the symptoms of anemia in piglets? First, sick pigs will have depression and loss of appetite. Malnutrition, the coat is reversed, the body temperature is not high, the visible mucous membrane is pale rose color, mild yellow stain. In severe cases, the mucous membrane is pale as white porcelain, and the ears are grayish white when exposed to light. Almost no obvious blood vessels are seen, and acupuncture also rarely bleeds. There are also sick pigs breathing and pulse are accelerated, you can hear anemia of intracardiac murmurs, a little exercise, the heart is rushing, breathing more than. Some piglets are very fat in appearance, and their growth and development are also fast. They can suddenly die during running, and typical anemia changes are observed by necropsy. From the above information, we can understand that the iron deficiency of piglets is very serious, and it is necessary to promptly supplement the piglets with iron. However, improper method of iron supplementation may result in irreparable damage. Introduction of correct iron supplementation methods for piglets 1. When the piglet is born, the iron in the body is not stored enough. In addition to the iron in the breast milk, the piglet gets all the nutrients. When a piglet is born, it takes only 50 mg of iron in the body and 7-10 mg of iron per day. 2. Newborn piglets do not get enough iron from breast milk. Only 0.02 mg per liter of breast milk (not included), if not timely iron supplementation, easily lead to piglets with iron deficiency anemia. 3. At present, most feed manufacturers use high copper to promote growth, which seriously affects the absorption of iron. High copper damages the pig's iron absorption, adding 120~240 mg/kg of copper to the feed, reducing the pig liver iron content by 50%~60%. 4. Only breastfed pigs are quickly anaemic. 70% to 7% of iron exists in the form of heme protein. The results showed that piglets need to maintain 7 to 16 mg of iron, maintain adequate hemoglobin and iron storage, but only 1 mg per liter of pig milk, so breast-fed piglets are very anaemic. Slow growth, low spirit, rough hair, wrinkles, mucous membranes; fast-growing pigs die from lack of oxygen; cold tolerance decreases, and the incidence and formation of stiff pigs increases. 5. Iron deficiency leads to immunocompromised studies conducted by people and experimental animals have shown that iron deficiency can reduce phagocytic function and reduce cellular and humoral immune responses. 6. Studies have shown that piglets may be more prone to diarrhea and supplement excess iron by oral route. Iron is also required for the growth and proliferation of intestinal bacteria, and excessive oral administration of iron may cause toxic diarrhea in E. coli. Heat treatment can also increase bacterial proliferation because heat treatment destroys iron and protein sequestration to increase inorganic iron. Iron supplementation method: feeding red soil: pig houses (rich in iron) in some deep red loam, let the pigs eat freely. 2 Iron and copper mixture: 2.5 g of ferrous sulfate, 1 g of copper sulfate, 100 ml of water, completely dissolve the mixture, filter paper or 4 to 8 layers of gauze, and store in brown glass bottles for use. 2 times a day, each time 0.5 ~ 1 ml / head, or 2.5 grams of ferrous sulfate, 2.5 grams of cobalt chloride, 1 gram of copper sulfate, 1000 ml of water, completely dissolved and filtered, 2 ~ 4ml per piglet, Feed to the sow's nipple or mixed feed or drinking water. I will introduce this to you today. Please pay attention to the pigs. After the pigs have supplemented the iron, some people must take care. If the piglets are found to be weak and have difficulty breathing, they should be treated promptly. When the iron is supplemented with iron, the standard must be operated to avoid Cause economic losses.
