- 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 et al., 2020). In poultry diets, supplementing with crystalline amino acids such as lysine and methionine optimizes amino acid balance, leading to increased digestibility coefficients and improved growth performance (Flickinger et al., 2016).
Similarly, in swine nutrition, crystalline amino acids enhance the efficiency of amino acid utilization, resulting in better feed conversion ratios (Zhao et al., 2019). The bioavailability of amino acids from crystalline sources is generally high due to their chemical purity and solubility, allowing rapid absorption in the small intestine (Cao et al., 2021). Studies have shown that crystalline amino acids can mitigate the negative negative effects of anti-nutritional factors present in plant-based ingredients, further improving digestibility (Khan et al., 2017). Moreover, precise supplementation of crystalline amino acids helps meet the specific amino acid requirements without excess protein intake, reducing nitrogen excretion and environmental impact (Zhou et al., 2020).
The kinetics of amino acid release from crystalline forms are rapid, facilitating better assimilation and utilization (Li et al., 2019). Overall, crystalline amino acids significantly enhance protein digestibility and amino acid bioavailability, thereby improving growth performance and feed efficiency in poultry and swine (Smith & Johnson, 2022). Future research should focus on the interactions between crystalline amino acids and dietary matrices to optimize their use (Kim et al., 2023).
