What is Ammonium Sulfate Used for in Feed Additives

Ammonium sulfate, chemically represented as (NH4)2SO4, is a versatile compound with a wide range of applications in agriculture, industry, and even in animal nutrition as a feed additive. This inorganic salt provides essential nutrients, including nitrogen and sulfur, to livestock, making it a valuable component in animal feed formulations. In this comprehensive guide, we will explore the diverse uses and applications of ammonium sulfate in animal nutrition, shedding light on its significance in the livestock industry and its impact on animal health and productivity.

what is ammonium sulfate used for:

Ammonium sulfate is one of the various feed additives utilized in animal nutrition to enhance the quality and nutritional value of animal feeds. It is an important source of both nitrogen (N) and sulfur (S), which are essential nutrients for animal health and growth. While the primary use of ammonium sulfate is in agriculture as a fertilizer, its role in animal nutrition is equally crucial.

1. Nutritional Role in Animal Feeds:

Ammonium sulfate serves several important functions in animal nutrition:

A. Nitrogen Source:Nitrogen is an essential element required for the synthesis of amino acids, proteins, and other vital biomolecules in animals. It plays a fundamental role in growth, reproduction, and overall animal development. Ammonium sulfate provides a readily available source of nitrogen in animal feeds, ensuring that livestock receive an adequate supply of this crucial nutrient.

B. Sulfur Source:Sulfur is another essential nutrient for animals, participating in various metabolic processes. It is a component of amino acids, vitamins, and enzymes. Sulfur deficiency can lead to poor animal growth, reduced feed efficiency, and health issues. Ammonium sulfate contributes sulfur to animal diets, helping meet their nutritional requirements.

2. Benefits and Applications in Animal Nutrition:

Ammonium sulfate is employed in animal nutrition for several important reasons:

A. Improved Protein Synthesis:The nitrogen provided by ammonium sulfate supports protein synthesis in animals. Adequate protein synthesis is essential for muscle development, immune function, and overall health.

B. Methionine Production:Sulfur from ammonium sulfate is used by animals to synthesize essential sulfur-containing amino acids, such as methionine and cysteine. Methionine is particularly important as it contributes to protein synthesis and serves as a precursor for various biologically active compounds.

C. Sulfur for Microbial Activity:Sulfur plays a role in rumen fermentation in ruminant animals like cattle and sheep. Sulfur-containing amino acids support the growth and activity of beneficial rumen microbes, aiding in the digestion of fibrous feeds.

D. Balancing Nutrient Profiles:Ammonium sulfate can help balance the nutrient profiles of animal feeds, especially those that may be deficient in nitrogen and sulfur. This is particularly important in regions with low-sulfur soils, where feedstuffs may lack sufficient sulfur content.

E. Acidifying Effect:Ammonium sulfate has an acidifying effect when added to animal feeds, which can be beneficial in certain situations. For example, it may help lower the pH of poultry litter and reduce ammonia emissions, improving air quality in poultry houses.

3. Types of Livestock and Feeding Scenarios:

Ammonium sulfate can be used in the nutrition of various livestock species, including:

A. Poultry:In poultry diets, ammonium sulfate is used to provide supplemental nitrogen and sulfur. It helps meet the amino acid requirements of broilers, layers, and turkeys, supporting their growth and egg production.

B. Ruminants:In ruminant nutrition, such as cattle and sheep, ammonium sulfate can be used to improve nitrogen utilization and microbial protein synthesis in the rumen. It is especially valuable when ruminants are fed high-fiber diets.

C. Swine:In swine nutrition, ammonium sulfate can be included in the diet to supply essential nitrogen and sulfur for growth and reproduction. It may be beneficial when formulating diets using locally available feed ingredients.

D. Other Livestock:Ammonium sulfate can also find application in the nutrition of other livestock species, such as goats, rabbits, and aquatic animals like fish and shrimp, where it helps balance nutrient requirements and support healthy growth.

4. Application and Considerations:

A. Feed Formulation:Ammonium sulfate is typically added to animal feed formulations to meet specific nutrient requirements. Its inclusion level in the diet is carefully calculated to achieve the desired nutrient balance.

B. Regulatory Compliance:The use of ammonium sulfate in animal feeds is subject to regulations and guidelines established by governmental agencies responsible for animal nutrition and agriculture. Feed manufacturers must ensure compliance with these regulations when formulating feeds.

C. Quality Assurance:Ensuring the quality and purity of ammonium sulfate used in animal feeds is essential. Contaminants or impurities can have adverse effects on animal health and product safety.

D. Research and Monitoring:Ongoing research and monitoring are critical to optimizing the use of ammonium sulfate in animal nutrition. This includes evaluating its effects on animal performance, health, and product quality.


Ammonium sulfate, (NH4)2SO4, is a valuable feed additive that plays a vital role in animal nutrition. By providing essential nitrogen and sulfur, it supports protein synthesis, growth, and overall animal health in various livestock species. Its ability to balance nutrient profiles, particularly in regions with nutrient-deficient feeds, underscores its significance in modern animal agriculture. Proper formulation and application of ammonium sulfate in animal diets can contribute to improved animal performance, efficient nutrient utilization, and sustainable livestock production. As ongoing research continues to enhance our understanding of its benefits, ammonium sulfate will remain an important component in the nutrition and management of livestock around the world.
