Embodiment 1
[0028] A method for supplementing iron for improving hepatic iron and hemoglobin of suckling pigs, comprising the following specific steps:
[0029] 1) Preparation of premix containing heme iron
[0030] Mix heme iron with 4% premix of sows to obtain a premix containing heme iron;
[0031] 2) Preparation of sow feed containing heme iron
[0032] Mix the premix prepared in step 1) with the corn-soybean meal type feed to obtain the sow feed containing heme iron;
[0033] 3) Feeding of pregnant sows
[0034] After the pregnancy test confirms that the sows are pregnant, they start feeding the sow feed containing heme iron prepared in step 2), and the use time is the whole gestation period of the sows.
[0035] In the present invention, the iron supplementation method for suckling piglets is scientific and reliable by adding heme iron in the ration of pregnant sows, which overcomes the defects and deficiencies of the current method of injecting heme iron supplementation for suck...
Embodiment 2
[0037] On the basis of Example 1, the amount of heme iron added is 30 mg per kilogram of sow feed. After mixing heme iron with premix and corn-soybean meal feed in a certain proportion, the iron absorption efficiency of sows and placenta can be improved. Iron transport efficiency.
Embodiment 3
[0039] On the basis of Example 1, the added amount of heme iron is 40 mg per kilogram of feed for sows, the ratio of heme iron to premix and corn-soybean meal feed is reasonable, and the absorption rate is high.
