Recent research indicates that the utilization of crystalline amino acids (like L-lysine, DL-methionine and L-threonine) varies significantly between commercial poultry and swine production systems. In poultry, crystalline amino acids such as lysine, methionine, and threonine are extensively used to optimize feed formulation and improve growth performance (Lemme et al., 2004). ). Poultry metabolism exhibits a […]

Crystallin amino acids (like L-lysine, DL-methionine, L-threonine), characterized by their high purity and stability, are increasingly utilized as dietary supplements to enhance protein quality in poultry and swine nutrition (Song et al., 2018). These amino acids can improve protein digestibility by providing available building blocks, reducing the need for endogenous enzyme activity during digestion (Liu […]

Optimizing the crystallin amino acid levels in the composition of poultry and swine feeds is critical for maximizing feed efficiency and growth performance (Parsons et al., 2012). Research indicates that methionine and cysteine are often the first limiting amino acids in poultry diets, and their adequate inclusion enhances feed conversion ratios (FCR) (De Groote et […]
