1. For Swine And Fish Diets: It is the third or fourth limiting amino acid in modern swine diets and typically a limiting amino acid in fish diets, which makes it a routine addition in pig and aquatic feed formulations.
2. Pet Nutrition: It is used as an essential amino acid in diets for cats and dogs, where the sulfur amino acid requirement has to be supplied through the feed rather than from the animal's own synthesis.
3. Nutrient For Foods, Supplements And Cell Culture: It is used as a nutrient in foods and dietary supplements, and it is supplied in high purity grades suitable for cell culture work, including insect cell culture.
