Pig manure fish production and fertilizer technology

September 09, 2025

Fermented pig manure is not typically used as feed for pigs due to its low nutritional value, but it makes an excellent Organic Fertilizer and fish feed. Many aquatic species, especially fish, enjoy consuming this fermented material. When applied to farmland, about two tons of fermented pig manure per acre can significantly improve soil quality. This organic fertilizer is safe, eco-friendly, and often outperforms chemical fertilizers in promoting plant growth. The fermentation process begins with 70% fresh pig manure (or alternatively, pigeon droppings or duck manure can be used if available). Mix in 15% corn flour, 10% grain bran, 5% wheat bran, and about 1,000 grams of Golden Baby Grade 2 Fermentation Starter per ton of the mixture. Thoroughly mix all ingredients, then add water until the moisture content reaches around 65%. Place the mixture in a sealed plastic bag or container and let it ferment for three days. In colder weather, the fermentation time may be extended slightly, while in summer, it may take just a couple of days. The process is complete when the odor disappears and a mild sour smell develops. Once fully fermented, the pig manure becomes a high-quality, environmentally friendly fertilizer. It can also be further processed into compound organic fertilizer. By using the Golden Baby II Fertilizer Starter, the process remains similar. After fermentation, approximately one ton of nutrient-rich material is produced. To enhance its effectiveness, allow it to air dry and then add 40 kg of urea, 58 kg of phosphate fertilizer, and 46 kg of potash per ton of pig manure—adjusting the quantities based on the specific crop being grown. Mix everything thoroughly, ensure the moisture level is reduced to about 40%, and finally package it for use. This method ensures a balanced, long-lasting fertilizer that supports sustainable agriculture.

Monocalcium Phosphate 22%

1. Monocalcium Phosphate (MCP) Product Description:
 
Monocalcium Phosphate (MCP) is a high-quality feed additive, widely used in livestock, poultry, and aquaculture feeds to provide essential phosphorus and calcium. These nutrients are critical for bone development, improved growth rates, and enhanced reproductive performance in animals. MCP is known for its high bioavailability, making it an efficient and cost-effective choice for animal nutrition.
 
2. Feed Grade Monocalcium Phosphate 22% Advantages:
 
1) High Phosphorus and Calcium Content: MCP offers an optimal phosphorus content (≥22%) and calcium content (≥16%), which supports bone growth and the overall health of animals.
 
2) Superior Bioavailability: MCP's digestible form of phosphorus ensures efficient absorption, promoting better feed conversion ratios and improved growth.
 
3) High Purity and Safety: Low in impurities and heavy metals, MCP is a safe and reliable feed additive that meets international feed safety standards.
 
4) Versatile Application: MCP is suitable for various feed formulations, including livestock, poultry, aquafeed, and pet food, supporting the nutritional needs of different animals.
 
3. Functions and Benefits
 
1) Optimal Bone Development: MCP supports the development of strong bones and teeth, essential for young and growing animals.
 
2) Improved Feed Efficiency: The high bioavailability of phosphorus and calcium in MCP improves nutrient absorption, leading to better feed conversion and animal growth.
 
3) Supports Reproductive Health: MCP enhances reproductive efficiency in breeding animals, increasing fertility and overall reproductive performance.
 
4) Boosts Immune Function: Adequate phosphorus and calcium intake contributes to a stronger immune system, helping to protect animals from diseases.
 
4. Application
 
1) Livestock Feed: MCP is widely used in feed for pigs, cattle, sheep, and goats, promoting bone strength and improving overall health and productivity.
 
2) Poultry Feed: In chickens, turkeys, and ducks, MCP improves eggshell quality, boosts growth rates, and enhances health.
 
3) Aquafeed: MCP is essential for fish and shrimp, supporting bone and skeletal health, which are vital for growth and development in aquatic animals.
 
4) Pet Food: MCP is used in high-end pet food formulas to ensure adequate calcium and phosphorus levels, promoting healthy bones and teeth in dogs and cats.
