Summary
Fish extracts from Trachurus trachurus enhance pig growth by modulating the immune system and reducing cholesterol. This study identifies a natural growth promoter and immune enhancer for swine diets.
Area of Science:
- Animal Science
- Immunology
- Nutritional Biochemistry
Background:
- Fish oils are known to modulate immune cell functions.
- Evidence suggests fatty acids, not trace elements or antioxidants, are responsible for fish oil's immune effects.
- Early-life immune modulation and growth enhancement are key objectives in pig farming.
Purpose of the Study:
- Identify a high-value fish species for improving pig nutrition.
- Utilize diets to modulate the immune system in young pigs.
- Enhance physiological growth rates in pigs.
Main Methods:
- A study involving 300 pigs supplemented with various fish extracts.
- Utilized advanced biotechnological methods for fish extract preparation.
- Focused on maximizing post-weaning feed intake to reduce stress and increase growth.
Main Results:
- Lipoproteins from Trachurus trachurus (E-JUR-94013) demonstrated immunomodulatory effects, primarily on immunoglobulin A (IgA) synthesis and release.
- E-JUR-94013 exhibited hypocholesterolemic properties, significantly reducing serum total cholesterol in treated pigs.
- Improved pig growth rates were observed, correlating with both immune modulation and cholesterol reduction.
Conclusions:
- Trachurus trachurus lipoproteins (E-JUR-94013) act as effective natural growth promoters in pigs.
- E-JUR-94013 serves as a natural immune enhancer, particularly through IgA regulation.
- This fish extract offers a dual benefit for swine, promoting growth and immune function simultaneously.
