The role of ferrous fumarate in pig feed
Ferrous fumarate is mainly used in pig feed to supplement iron elements, prevent iron deficiency anemia, and promote growth and development, improve meat quality and appearance.
Core functions and mechanisms of action
1. Prevention and treatment of iron deficiency anemia
Ferrous fumarate, as a highly efficient organic iron source, can directly participate in the synthesis of hemoglobin and myoglobin, effectively preventing anemia, diarrhea, and immune deficiency in piglets caused by iron deficiency. Research has shown that adding this substance to sows from 2 weeks before delivery to 3 weeks after delivery can transfer iron to piglets through breast milk, with an effect comparable to intramuscular iron supplementation.
2. Promote growth and development
Improve feed conversion rate: By enhancing the activity of iron containing enzymes, accelerating the tricarboxylic acid cycle metabolism, and improving energy utilization efficiency;
Improving daily weight gain: Experimental data shows that adding ferrous fumarate can increase daily weight gain in pigs by 5-10%;
Reduce breeding costs: Compared to amino acid chelated iron, it is more cost-effective and avoids the damage of inorganic iron to vitamins.
3. Improve appearance and product quality
Make pig skin rosy and hair shiny, enhance product appearance;
Increase muscle myoglobin content and improve meat color;
Reduce the hatching rate of eggs and improve reproductive performance in pig farming.
Comparison of application advantages
Efficient absorption: The intestinal absorption rate is several times that of ferrous sulfate, and it does not antagonize trace elements such as zinc and copper;
High safety: with an iron content of 33%, strong stability, and a lower risk of excess compared to inorganic iron;
Synergistic effect: Good compatibility with feed additives such as antibiotics and vitamins.
Usage suggestions
Addition stage: The best effect is achieved during the late pregnancy to lactation period of sows and the weaning period of piglets;
Dose control: Refer to the recommended dosage of 60-120mg/kg feed, and adjust according to the health status of the pig herd;
Caution: Avoid co administration with theophylline substances and regularly monitor serum iron levels.
