Application of ferrous fumarate in concentrated feed for early weaned piglets
The application of ferrous fumarate in concentrated feed for early weaned piglets is mainly reflected in improving growth performance and preventing anemia. The following are specific research conclusions:
Test effect
The experiment conducted by Zhang Wenli and Yi Zongrong in 2007 showed that when ferrous fumarate (Group 2) was added to concentrated feed for early weaned piglets at 28 days of age in combination with high copper, the daily weight gain and feed conversion rate of piglets were better than those of the control group that only added high copper or only the required amount of copper for nutrition, demonstrating the best feeding effect.
Iron supplementation effect
Ferrous fumarate, as an organic iron source, has a higher biological potency than inorganic iron. When used in combination with glycine iron, methionine iron, etc., it can meet the iron element requirements for piglet growth, achieve the same weight gain effect as intramuscular injection of iron dextran, and avoid stress reactions caused by iron supplementation.
Applicability
The addition amount of ferrous fumarate in feed is 200-400 grams per ton of feed, which can prevent iron deficiency anemia and improve skin and hair condition. Its cost is lower than amino acid chelated iron, and its effect is better than inorganic iron sources (such as ferrous sulfate), making it suitable for large-scale aquaculture.
