“…The ideal amino acid composition for human nutrition and that for livestock are very similar, but the required amounts for the latter are usually higher; for example, while lysine (the most limiting amino acid in cereals) requirement for humans is 30 mg kg −1 day −1 , 41 for pigs it is approximately 20% higher and it has been difficult to agree on the precise level required. 42,43 The amino acid contents of grain legumes in our trial are mostly in agreement with values reported elsewhere; except that methionine was 19% higher in narrow-leafed lupin 44 and cysteine was 36% lower in faba bean. 25 The lower content of cysteine in faba bean grown in Finland should not be considered a disadvantage, since cysteine is produced from methionine in most monogastrics, including humans.…”

“…Values for the rat, pig and human are shown in Table 4 as mg/kg 0·75 . The summary of pig values reported most recently ( 40 ) includes values obtained by a variety of different approaches by 5 different authors some of which include slightly higher values than these summarized here but which the authors identified as potential overestimates. Had these been included the mean of all the studies would be slightly higher at 48 mg/kg 0·75 or 15 mg/kg.…”

The 1985 FAO/WHO/UNU protein report defined reference amino acid patterns for infants based on breast milk and for preschool children, schoolchildren and adults from age specific estimates of dietary indispensible amino acid requirements divided by the safe protein requirement for each age group. This report argued that the protein quality of a diet should be estimated from its digestibility adjusted by its amino acid score calculated from its limiting amino acid in comparison with the reference amino acid pattern. Subsequently a joint FAO/WHO expert consultation on protein quality evaluation (1991) endorsed this protein digestibility-corrected score approach. However it rejected the adult scoring pattern identified in the 1985 report arguing that the amino acid values for this pattern were too low. As an interim measure it suggested that the scoring pattern for preschool children should be used for all age groups apart from infants. The recent WHO/FAO/UNU (2007) report endorsed the 1985 report in recommending the amino acid content of breast milk as the best estimate of infant amino acid requirements. However it was only able to identify reliable requirement values for adults and adopted a factorial approach to derivation of age-related scoring patterns. This utilized the adult pattern for maintenance, and the pattern of human tissue protein for growth. Thus scoring patterns were derived for children aged 0·5, 1-2, 3 -10, 11-14, 15-18 years and for adults. The total dietary amino acid requirements calculated for these age groups were divided by the mean protein requirement to give the scoring pattern which should be used to adjust digestible intakes to identify the available protein in specific diets. However because the adult values were determined in subjects at protein intakes much higher than the mean minimum protein requirement, i.e. at 1 g/kg/d rather than 0·66 g/kg/d, the pattern is likely to include higher values than the minimum requirement and should therefore be referenced against the safe allowance.

“…Several studies were conducted to determine total requirements (maintenance and deposition) of lysine for growing pigs (Heger et al, 2008;Van Milgen et al, 2008;Ringel & Susenbeth, 2009). However, in Brazil, there are few studies on the maintenance requirements and efficiency of lysine for protein deposition, obtained separately.…”

-The objective of this work was to determine the maintenance requirement and the deposition efficiency of lysine in growing pigs. It was used the incomplete changeover experimental design, with replicates over time. Twelve castrated pigs with average body weight (BW) of 52±2 kg were kept in metabolism crates with a controlled temperature of 22°C. The diets were formulated to supply 30, 50, 60, and 70% of the expected requirements of standardized lysine, and provided at 2.6 times the energy requirements for maintenance. The trial lasted 24 days and was divided into two periods of 12 days: seven days for animal adaptation to the diet and five days for sample collection. The increasing content of lysine in the diet did not affect dry matter intake of the pigs. The amount of nitrogen excreted was 47% of the nitrogen intake, of which 35% was excreted through feces and 65% through urine. The estimated endogenous losses of lysine were 36.4 mg kg -1 BW 0.75 . The maintenance requirement of lysine for pigs weighing around 50 kg is 40.4 mg kg -1 BW 0.75 , and the deposition efficiency of lysine is 90%.Index terms: amino acid requirement, nitrogen, pig production, swine nutrition. Exigência de manutenção e eficiência de deposição de lisina em suínosResumo -O objetivo deste trabalho foi determinar a exigência de manutenção e a eficiência de deposição de lisina em suínos em crescimento. Utilizou-se o delineamento experimental permutável, com repetições ao longo do tempo. Doze suínos castrados com peso vivo (PV) médio de 52±2 kg foram alojados em gaiolas metabólicas, com temperatura controlada de 22°C. As dietas foram formuladas para fornecer 30, 50, 60 e 70% das exigências esperadas de lisina estandardizada e fornecidas para atender 2,6 vezes a exigência de energia para manutenção. O experimento teve duração de 24 dias e foi dividido em dois períodos de 12 dias: sete para adaptação dos animais à dieta e cinco para coleta de amostras. O teor crescente de lisina na dieta não influenciou a ingestão de matéria seca pelos suínos. A quantidade de nitrogênio excretado foi de 47% do ingerido, dos quais 35% foram excretados pelas fezes e 65% pela urina. As perdas endógenas de lisina estimadas foram de 36,4 mg kg -1 PV 0,75 . A exigência de manutenção de lisina em suínos com aproximadamente 50 kg é de 40,4 mg kg -1 PV 0,75 , e a eficiência de deposição de lisina é de 90%.Termos para indexação: exigência de aminoácidos, nitrogênio, suinocultura, nutrição de suínos.
