“…Although the present meta-analysis did not show any effect of BW, feeding level or indigestible marker on IAA end , there is evidence from individual literature reports that these factors contribute, at least in part, to the large variation in IAA end (Fan and Sauer, 2002;Leterme and Théwis, 2004;Moter and Stein, 2004;Høøk Presto et al, 2010). According to Hess and Sève (1999), IAA end may decrease with increasing BW of pigs in the weight range from 45 to 80 kg.…”

“…Furthermore, mean IAA end values (except for Arg, Thr, Trp, Gly) in the present study where higher compared with the corresponding IAA end in the studies of Stein et al (1999) and Dolešová et al (2009). In conclusion, large standard deviations for IAA end obtained in the present study reflect considerable variation in IAA end between the studies included in the meta-analysis.Although the present meta-analysis did not show any effect of BW, feeding level or indigestible marker on IAA end , there is evidence from individual literature reports that these factors contribute, at least in part, to the large variation in IAA end (Fan and Sauer, 2002;Leterme and Théwis, 2004;Moter and Stein, 2004;Høøk Presto et al, 2010).

This meta-analysis aimed to estimate the standardized ileal digestibility (SID) and the basal ileal endogenous amino acid losses (IAA end ) in barley for growing pigs. In total, 38 different barley treatments published in 26 peer-reviewed papers were used for the meta-analysis containing information on dietary composition including amino acid (AA) contents of the assay diets, and (or) barley samples, as well as apparent ileal digestibility (AID) of AA in barley. The SID of AA was determined by either correcting AID of AA for their IAA end or by regression analysis between the apparent ileal digestible and total dietary AA contents. The SID values obtained by correcting the AID values for their IAA end amounted to 70%, 77%, 74% and 63% for Lys, Met, Thr and Trp, whereas those based on regression analysis method were 82%, 82%, 69% and 55%, respectively. Estimates of basal ileal endogenous loss of CP in ileal digesta varied considerably and averaged 11.84 g/kg dry matter intake (DMI), whereas IAA end for indispensable AA ranged from 0.05 g/kg DMI for Trp to 1.90 g/kg DMI for Leu. In most cases, these estimates were considerably higher than previously reported values for IAA end . The results of the present regression analysis indicate for most AA higher SID values compared with SID of most AA that were obtained by correcting AID values for IAA end . In view of the observed high variations in IAA end and the low CP content of the barley samples, estimating SID of AA based on literature data by means of the regression method may improve accuracy of SID coefficients for barley. In contrast, transformation of AID values into their corresponding SID values by using a constant correction factor for IAA end adds an additional source of error, thereby reducing the precision in estimating SID of AA.Keywords: amino acids, meta-analysis, pigs, standardized ileal digestibility, barley ImplicationsRegression analyses between the apparent ileal digestible and the total dietary amino acid (AA) content in barley samples have proven to be superior over the calculation of standardized ileal digestibility (SID) by correcting apparent ileal digestibility (AID) values for their ileal endogenous amino acid (IAA end ). According to regression analysis, SID of most AA in barley was >80%, whereas SID of most AA obtained by correcting AID values for IAA end was below 80%. In particular, lower SID of Lys, Thr and Trp in comparison to other indispensable AA need to be compensated for, for example, through supplementation with crystalline AA in barley diets for pigs. IntroductionThe world production of barley amounts to over 134 million tons annually (FAOSTAT, 2011), therefore, and due to its low purchase cost, barley is the most important crop in diets for livestock after wheat and maize (Leterme et al., 2000;Hennig et al., 2006; FAOSTAT, 2011). The protein content of cereal grains including barley is considerably lower than that of protein supplements such as soya bean meal, but due to their high dietary inclusion level, cereal grains can su...

“…In the present study, the digestibility of the TLM was not affected by the rate of incorporation, even at 300 g TLM per kg diet. The difference can be ascribed to the better capacity of large animals to ingest and digest high fibre diets (Leterme and Thé wis, 2004;Noblet and Van Milgen, 2004). The weight of the gastro-intestinal tract of growing pigs increases when they are given high fibre diets (Anugwa et al, 1989).…”

Tree leaf meals (TLM) are increasingly used in the tropics to feed pigs. The nutritive value of the TLM of cocoyam (Xanthosoma saggitifolium), mulberry ( Morus alba) and Trichanthera gigantea, their effect on the digestive tract and their fermentation rate in the large intestine, were determined in adult sows given diets containing 150 or 300 g TLM per kg. The TLM contained from 8·5 to 12·0 MJ digestible energy per kg dry matter (DM) and from 60 to 125 g digestible protein per kg DM. The digestibility was not affected ( P . 0·05) by their rate of incorporation in the diet. The apparent ileal protein digestibility of the diets containing 300 g TLM per kg was also determined by the slaughtering method. It reached 80% for the basal diet and 54, 70 and 74% for the Trichanthera-, mulberry-and cocoyam-based diets, respectively. No diet effect ( P . 0·05) was observed on the weight and length of the gastro-intestinal tract, with the exception of a heavier caecum in sows given the Trichanthera-based diet ( P , 0·01). The pH of the gastric fluid of these sows was also higher ( P , 0·001). The fermentation of the dietary fibre in the large intestine was evaluated by the gas technique using syringes. The cocoyam leaves presented the highest amount of total gas produced after fibre fermentation ( P , 0·001). The ranking order of gas production was identical to that observed for the digestibility coefficients: Trichanthera , mulberry , cocoyam. In conclusion, TLM can represent up to 0·3 of a diet for sows. Their use in sow nutrition may be considered in tropical regions where protein sources are scarce.

“…The values presented by Gottlob et al (2006) were measured in pigs that weighed more than 30 kg, but, in the present experiment, values were measured in weanling pigs. Endogenous AA losses decrease as pigs become older (Leterme and Thewis 2004), which results in lower calculated values for AID and SID in young pigs compared with older pigs. The reason for the lower values for AID and SID obtained in this experiment as compared with the experiment by Gottlob et al (2006) may, therefore, be the difference in the weight of the pigs used in the two studies.…”

. 2007. Apparent and standardized ileal digestibility of amino acids in yeast extract and spray dried plasma protein by weanling pigs. Can. J. Anim. Sci. 87: 381-383. The objective of this experiment was to measure the apparent (AID) and standardized (SID) ileal digestibility of crude protein (CP) and amino acids (AA) in yeast extract and spray dried plasma protein (SDPP) by weanling pigs. A casein-based diet, a casein-SDPP diet, a casein-yeast extract diet, and a N-free diet were formulated and fed to weanling pigs. Values for AID and SID in yeast extract and SDPP were calculated using the difference procedure. Results showed that the AID for CP and all AA with the exception of Cys and Ser are similar between yeast extract and SDPP. Likewise, no differences in SID for CP or AA were observed between yeast extract and SDPP. The current data demonstrate that both yeast extract and SDPP contain protein that is relatively well digested by young pigs. Mots clés: Acides aminés, digestibilité, porcs, sang séché par pulvérisation, extrait de levure 381Spray dried plasma protein (SDPP) is a commonly used protein source in diets fed to weanling pigs (Cho et al. 1997;Chae et al. 1999). It is produced by adding an anticoagulant to the blood from slaughtered animals. The erythrocytes are separated from the plasma by centrifugation and the plasma obtained is then spray-dried to produce the final product called SDPP (Howell and Lawrie 1983). An alternative nonanimal protein source that is currently being introduced to the market is yeast extract, which is derived from yeast cell contents by removing the cell wall from the yeast cells (Tibbets 2002). Yeast extract contains 48.8% crude protein (CP) and relatively high quantities of amino acids (AA) and nucleotides. The inclusion of yeast extract in diets fed to weanling pigs has been reported to improve pig performance and intestinal health (Maribo 2003;Carlson et al. 2005). It was also observed that subsequent grower and finisher performance was improved for pigs that were fed yeast extract during the nursery phase (Carlson et al. 2005). As a consequence, there is considerable interest in using SDPP and yeast extract in diets fed to weanling pigs. However, apparent (AID) and standardized (SID) ileal digestibility values for CP and AA in yeast extract have not been reported. Digestibility values for AA in SDPP have been reported on a few occasions (Cho et al. 1997;Chae et al. 1999;Gottlob et al. 2006), but these values were measured in growing pigs, and it is not known if they are also representative of values for AID and SID in weanling pigs.
