Iron supplementing method for improving liver iron and hemoglobin of piglets

Abstract

The present invention belongs to the technical field of sow feeding, and particularly relates to an iron supplementing method for improving the liver iron and the hemoglobin of piglets. The iron supplementing method comprises: 1) preparing of a heme iron-containing premix: mixing heme iron and the 4% premix of sow to obtain the heme iron-containing premix; 2) preparation of a heme iron-containing sow material: mixing the premix prepared in the step 1) and a corn-bean meal type feed to obtain the heme iron-containing sow material; and 3) feeding of pregnant sows: feeding the heme iron-containing sow material prepared in the step 2) after the pregnancy detection results determine that the sow is pregnant, wherein the feeding time is the whole pregnancy period of the sow. According to the present invention, the iron supplementing method adding the heme iron to the pregnant sow feed is scientific and reliable, overcomes the defects and the disadvantages of the existing iron supplementing method using the injection of dextriferron in piglets, does not produce bad skin iron absorption and cross infection to piglets, makes the piglet hemoglobin content be increased to the normal level, and has the good iron supplementing effect.

Description

technical field [0001] The invention belongs to the technical field of sow feeding, and in particular relates to an iron supplement method for increasing liver iron and hemoglobin of suckling piglets. Background technique [0002] Due to the sow placental barrier and mammary gland barrier, the addition of inorganic iron sources to sow diets cannot effectively increase the liver iron content of newborn piglets, and cannot meet the needs of hemoglobin synthesis in suckling piglets. If the piglets are not supplemented with iron in time after birth, it is easy to cause anemia in the piglets, which will affect the health and growth performance of the piglets. The current method of iron supplementation for suckling piglets is generally within 3 days to 5 days after the piglets are born, intramuscularly injecting hemoglobin with an iron content of 150-200 mg / ml / time to achieve the purpose of increasing the hemoglobin content of piglets and preventing anemia in piglets .

AI Technical Summary

Problems solved by technology

[0003] There are the following defects and deficiencies in the commonly used methods of intramuscular injection of hematin for suckling piglets in piglet production: poor absorption of iron by the skin, cross-infection, high cost, relatively slow increase of suckling piglet hemoglobin content, thus affecting the health of piglets.
