Casein Protein in Animal Feed Application Market Report 2026

The casein protein in animal feed application market size has grown rapidly in recent years. It will grow from $3.34 billion in 2025 to $3.77 billion in 2026 at a compound annual growth rate (CAGR) of 12.7%. The growth in the historic period can be attributed to increasing livestock population, expansion of commercial animal farming, rising demand for protein-rich feed ingredients, availability of dairy by-products, growing awareness of animal nutrition quality.

The casein protein in animal feed application market size is expected to see rapid growth in the next few years. It will grow to $6.14 billion in 2030 at a compound annual growth rate (CAGR) of 13%. The growth in the forecast period can be attributed to increasing demand for high-efficiency animal feed, rising focus on livestock productivity optimization, expansion of premium animal nutrition products, growing investments in feed formulation innovation, increasing adoption of functional feed additives. Major trends in the forecast period include increasing use of high-protein feed supplements, rising demand for essential amino acid fortification, growing adoption of dairy-derived feed ingredients, expansion of specialized livestock nutrition formulations, enhanced focus on feed digestibility and performance.

The expanding animal health sector is expected to significantly drive the growth of the casein protein market for animal feed applications. Animal health companies have recognized the challenges of raising animals in a rapidly changing environment and are showing resilient growth. Casein protein, a dairy protein derived from the milk of various mammals, offers numerous nutritional benefits and is used in a variety of products, including cheese, nutritional supplements, coatings, and pharmaceuticals. As the animal health sector grows, so does the demand for casein protein in animal feed. For instance, in April 2024, EuroDev Group, a Netherlands-based non-governmental organization, reported that the European companion animal healthcare market is projected to increase from USD 3.96 billion in 2022 to USD 5.37 billion by 2027, representing a growth rate of 6.25%. Additionally, Europe led global pet food production in 2022, producing 11.78 million metric tons, surpassing North America's 11.2 million metric tons. Therefore, the growth of the animal health sector is driving demand for casein protein in animal feed applications.

The rise in meat consumption is anticipated to significantly boost the growth of the casein protein market for animal feed applications. Meat consumption involves incorporating animal-derived meat into diets, and livestock raised for meat production require protein-rich diets to support optimal muscle growth and overall health. Casein serves as a complete protein source, providing essential amino acids necessary for effective muscle development. For instance, in 2024, Carlisle Technology, a Canada-based provider of advanced hardware and software solutions for the meat industry, reported that the per capita consumption of broiler chicken in the U.S. was 98.9 pounds in 2022, with projections suggesting it will increase to 107.5 pounds by 2033. Chicken remains the most consumed meat in the country, reflecting a growing preference among American consumers. Therefore, the rise in meat consumption is driving the demand for casein protein in the animal feed application market.

Product innovations are emerging as key trends in the casein protein market for animal feed applications. Major companies in this sector are focused on developing new products to strengthen their market position. For example, in September 2023, Pureture, a US-based biotechnology company, launched a plant-based casein. Traditional casein, found in animal-based dairy products, helps maintain a stable emulsion that prevents water and fat from separating, resulting in a smooth texture in milk. Many vegan cheeses lack casein, leading to issues with stretchiness and meltability. To address this, researchers at Pureture have developed a proprietary yeast-based technology that mimics casein's functionality using entirely plant-based ingredients, enhancing both nutrition and flavor. This innovative solution is not only cost-effective and sustainable but also eliminates the need for gums, starches, and emulsifiers.
