Amt Amount, BW Body weight, DM Dry matter of diet, EAAs traditionally nutritionally essential amino acids, Hyp 4-hydroxyproline, LG Late gestation, ME Metabolizable energy, NEAAs traditionally nutritionally nonessential amino acids, NP Non-pregnant and non-lactating, NRC National Research Council, PL Peak lactation, P1G the last 24 d of pregnancy of first-parity swine, P1LS first-parity lactating sows
  2. “–” data are not available
  3. a Referring to 4- to-14-week-old dogs for EAAs. The recommended allowance of dietary crude-protein for ≥14-week-old growing dogs is 175 g/kg DM
  4. b The ratio of proline to 4-hydroxyproline is 18.6:1.0, g/g
  5. c Present work. It is assumed that the recommended allowance of dietary crude-protein for adult dogs is 10%, dry matter basis
  6. d It is assumed that the recommended allowances of dietary crude-protein for growing and young adult cats are 30% and 26%, respectively, on the dry matter basis [140]. The recommended allowances of dietary EAAs for growing cats (g/kg dry matter of diet) are: Arg, 26.8; Cys, 6.3; His, 16.3; Ile, 21.0; Leu, 34.1; Lys, 36.8; Met, 12.9; Phe, 17.1; Thr, 18.9; Trp, 5.1; Tyr, 15.4; and Val, 24.3. The recommended allowances of dietary EAAs for young adult cats (g/kg dry matter of diet) are: Arg, 23.3; Cys, 6.3; His, 14.0; Ile, 18.3; Leu, 29.5; Lys, 31.9; Met, 11.3; Phe, 14.9; Thr, 16.4; Trp, 4.4; Tyr, 13.4; and Val, 21.0. The recommended allowances of dietary crude-protein for young and adult cats are 1.25 times their minimum dietary requirements for crude protein
  7. e Different breeds of swine have different body weights at young and adult ages. For the offspring of Yorkshire × Landrace sows and Duroc × Hampshire boars with a normal birth weight, 6- and 110-kg body weights correspond to approximately 3 weeks and 6 months of age. At about 18 months of age (adult), the lean-tissue weight curve of swine is flattened. The dietary requirement of adult swine for crude protein is approximately 100 g/kg dry matter
  8. f Values refer to amino acid content, rather than digestible amino acid content, in the diet
