In recent years, with the development of large-scale, intensive and modernized pig industry, large-scale pig farms occupy an absolute majority in the overall breeding population. In the traditional pig raising, the inside of the house is the land surface. Before the feeding of the piglets, the sows can lead the piglets to obtain some iron supplements during the process of arching the soil. At the same time, the pig breeds in the traditional pigs are worse than the current large-scale pig farms. Farther, of course, the growth rate is also quite different from that of large-scale pig farms. However, the supplement of iron in the traditional pig raising process is still one of the important tasks of most pig farms; the modern large-scale pig farms are closed. The management mode is different from the traditional pig raising. The sow can't get the power to lead the piglet to live freely. The building is mainly made of cement floor. It can't get all the trace elements needed for the body to grow from the soil, so it can only rely on the outside world. The supplement, which is directly supplemented or derived from feed, is therefore more important in the daily management of piglets in large-scale pig farms. Here, the author combines the actual situation of the pig farm to describe the various precautions for iron supplementation during the pig raising process for reference.
1 The choice of iron time
The reason that newborn piglets are prone to iron deficiency anemia is due to insufficient iron storage in newborn piglets. According to the study, newborn piglets have an iron storage of about 40-50 mg at birth. In the process of growing piglets, about 7 to 16 mg of iron per day is required to ensure a faster growth rate. The only source of iron for newborn piglets is breast milk, and each newborn pig receives only about 1 mg of iron per day through breast milk. Therefore, the iron storage in the 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 performed on newborn piglets within 4 days of age, otherwise iron deficiency anemia will occur. Piglets that cause lack of energy, loss of appetite, diarrhea, slow growth, and even faster growth can suddenly die from lack of oxygen.
2 Selection of iron supplements
2.1 Strict quality control, farms (households) should be careful when choosing iron supplements. First, we must select the products produced by the GMP-certified and listed companies, and check the production date, expiration date, packaging, etc., in order to prevent unnecessary losses caused by the use of unqualified or expired products.
2.2 Specification selection The iron supplements currently used are more iron injections of dextran, the specifications are 50mg/ml, 100mg/ml, 150mg/ml, and the production of “Fuxuewang†with a specification of 150 mg/ml is produced by Zhengbang Sports Insurance. Iron preparation. The high iron content of dextran and the better production process make the particle of the drug solution smaller, the irritation to piglets is small, the absorption is fast, and the extraction and injection are extremely convenient. In addition, the additional selenium, cobalt and multivitamin B can be supplemented by one needle, and the effect is comprehensive, which is more conducive to the comprehensive absorption of iron. At the same time, it can promote the further improvement of the body's hematopoietic function and increase the iron content in the process of hematopoiesis. Utilization rate.
