In swine nutrition, minimizing the oxidation of imbalanced amino acids is an important issue in optimizing the use of feed resources. Numerous titration studies have been conducted to determine the optimum lysine-to-energy ratio, increasingly using within-animal titration approaches. Whether or not amino acid requirements depend on the level of feed intake has been subject of debate, with some studies indicating lower lysine requirements with increasing starch intake (Kampman-Van de Hoek et al., 2013), whereas others found no change with feeding level (Bikker et al., 1994). |
