Introduction

In the constantly evolving field of animal nutrition, the demand for cost-effective, high-performance feed ingredients is increasing. Among the various protein and mineral sources available, yeast paraffin-grown has emerged as a valuable and multifunctional feed ingredient. Its unique nutritional profile, including high levels of protein, essential amino acids, trace minerals (Mn, Zn, K), and B-complex vitamins (choline, nicotinic acid, and folic acid), makes it an attractive alternative to traditional feed supplements. This article explores the production process, nutritional composition, benefits, and feeding advantages of Yeast grown paraffin  in animal nutrition.

What is Yeast Paraffin-Grown ?

Yeast grown paraffin  refers to yeast that is cultivated on paraffin or hydrocarbon-based substrates as a carbon source. The yeast species used for this process are typically from the Candida genus (such as Candida tropicalis or Candida lipolytica), known for their ability to metabolize hydrocarbons efficiently.

Nutritional Composition of Yeast Paraffin-Grown

Yeast grown paraffin  is highly valued for its balanced nutrient profile and high digestibility. Its key components include:

1. High Protein Content

• Contains 45%–60% crude protein, making it a competitive alternative to fish meal and soybean meal.
• Provides a balanced amino acid profile, rich in lysine and threonine, supporting muscle development and growth.

2. Essential Trace Minerals

1] Manganese (Mn): Present at 250 mg/kg – supports bone development, eggshell quality, and enzyme function.

           Deficiency Diseases:

• Perosis (slipped tendon): Caused by poor bone development in poultry.
• Reduced eggshell strength and hatchability.
• Poor growth and bone deformities.

2] Zinc (Zn): Present at 1300 mg/kg – essential for immunity, skin health, and protein synthesis.

Deficiency Diseases:

Parakeratosis:

3] Potassium (K): Present at 12.8 mg/kg – regulates acid-base balance and muscle function.

Deficiency Diseases:

• Muscle weakness and tremors.
• Reduced feed intake and poor growth.
• Poor eggshell quality and reduced production.

3. High B-Complex Vitamin Content

1]  Choline (6,225 mg/kg): Supports fat metabolism and nerve function.

Deficiency Diseases:

• Fatty liver syndrome (due to impaired fat metabolism).
• Poor growth and reduced feed conversion.

2] Nicotinic Acid (430 mg/kg): Improves energy metabolism and skin health.

Deficiency Diseases:

• Pellagra-like symptoms: Dermatitis, diarrhea, and weakness.
• Poor feathering and skin lesions.

3] Folic Acid ( 64 mg/kg): Essential for DNA synthesis and reproductive health.

Deficiency Diseases:

• Pellagra-like symptoms: Dermatitis, diarrhea, and weakness.
• Poor feathering and skin lesions.

4. Low Fat and High Energy Value

• Yeast grown paraffin provides a moderate energy value due to its low fat but high protein and carbohydrate content.
• The yeast cell wall contains beta-glucans and mannan oligosaccharides (MOS) that enhance gut health and immunity.

Advantages of Yeast grown paraffin  as a Feed Ingredient

 1. High Bioavailability of Minerals and Vitamins

• Minerals and vitamins from yeast are naturally chelated (bound to organic molecules), enhancing their absorption and utilization compared to inorganic forms (like oxides and sulfates).
• The organic form of minerals reduces the risk of antagonism between nutrients (e.g., excess zinc interfering with copper absorption).

 2. Dual Role as a Protein and Mineral Source

• Unlike other mineral and vitamin supplements, Yeast grown paraffin provides both high-quality protein and essential trace elements.
• This dual role reduces the need for additional protein or mineral supplementation, simplifying feed formulation.

 3. Gut Health and Immunity Booster

• Beta-glucans and MOS in yeast cell walls stimulate the immune system and promote beneficial gut microflora.
• Reduced incidence of digestive disorders and improved feed conversion efficiency.

4. Heat and Environmental Stress Tolerance

• Nicotinic acid (niacin) supports vasodilation and energy metabolism, improving performance under heat stress.
• Choline aids in fat metabolism and prevents fatty liver in heat-stressed animals.

5. Improved Growth, Reproductive Performance, and Eggshell Quality

• Manganese and zinc enhance bone strength and eggshell quality in poultry.
• Folic acid and niacin support cell division, improving fertility and hatchability.
• High choline levels boost growth rate and carcass quality.

6. Sustainable and Cost-Effective Production

• Uses paraffin, a by-product of the petroleum industry, as a substrate – reducing waste and lowering production costs.
• Lower inclusion rates due to high nutrient density make it a cost-effective ingredient

Recommended Inclusion Rates

• Poultry: 2%–5% of total diet
• Swine: 2%–4% of total diet
• Aquaculture: 2%–3% of total diet

Conclusion

Yeast grown paraffin  stands out as a high-quality protein source enriched with essential trace minerals (Mn, Zn, K) and B-complex vitamins (choline, niacin, folic acid). Its dual role as a protein and mineral supplement, combined with enhanced bioavailability and gut health benefits, makes it an ideal ingredient for improving animal performance and reducing feed costs. While processing challenges such as nucleic acid content and hydrocarbon residues require careful management, the overall benefits of Yeast grown paraffin  make it a valuable addition to modern livestock and poultry diets.
