Choline chloride is widely used as an additive in animal feed, particularly for poultry, swine, and cattle. It serves as a source of choline, which is essential for proper liver function, nerve transmission, and fat metabolism in animals. In poultry, it helps prevent conditions like perosis and fatty liver syndrome, improving overall growth and egg production. In aquaculture, it is added to fish feed to enhance growth rates and support healthy development. Additionally, choline chloride is used in the pet food industry to ensure proper nutrition for dogs and cats. Outside of animal nutrition, it finds applications in industrial processes, such as in concrete admixtures to improve workability and reduce water content. It is also utilized in oil and gas drilling fluids to stabilize clay formations and prevent swelling.
