The inclusion of crystallin amino acids in poultry and swine diets has been shown to enhance growth performance by optimizing amino acid availability and reducing dietary crude protein levels (Lemme et al., 2004). Crystallin amino acids (like L-lysine, DL-methionine and L-threonine), being highly bioavailable, improve feed efficiency and promote muscle development, leading to increased weight gain (NRC, 2012). In broiler chickens, supplementation with crystalline amino acids such as lysine and methionine has been linked to improved feed conversion ratios and carcass quality (Kidd et al., 2014). Similarly, in swine nutrition, crystalline amino acids help meet the precise amino acid requirements, reducing nitrogen excretion and supporting lean tissue growth (Wu et al., 2015). The use of crystalline amino acids also allows for greater dietary formulation flexibility, minimizing excess amino acids that can negatively impact gut health and growth (Flickinger et al., 2007).
Moreover, supplementation of crystalline amino acids has been observed to mitigate the effects of amino acid imbalances, thus promoting more consistent growth rates (Lemme et al., 2004). In both poultry and swine, this strategy can lead to improved feed efficiency, reduced feed costs, and enhanced overall productivity (NRC, 2012). However, excessive inclusion of crystalline amino acids may lead to imbalanced amino acid profiles and metabolic stress, emphasizing the importance of precise formulation (Kidd et al., 2014). Overall, the strategic use of crystalline amino acids is a valuable tool in optimizing growth performance in commercial poultry and swine production systems (Wu et al., 2015). Future research should focus on understanding the long-term impacts of crystalline amino acid supplementation on animal health and product quality (Flickinger et al., 2007).
