“…In general, the AID of AA in RH barley were within the range of values reported in the literature (Fan and Sauer 1995;Nyachoti et al 1997;Reverter et al 1999). The SID values for AA obtained in the present study were similar to the values reported by Pedersen et al (2007) for regular barley. Although the barley samples did not have differences in SID of AA, because of the high absolute contents (Table 1) of AA in LP barley, the calculated SID contents for most of AA were higher (P B0.05) for LP barley (Table 2).…”

. 2010. Energy and nutrient digestibility in a hulless low-phytate phosphorus barley fed to finishing pigs. Can. J. Anim. Sci. 90: 393Á399. Six-ileal cannulated finishing barrows were used to determine energy and nutrient digestibility in a sample of a hulless low-phytate (LP) barley cultivar. A sample of regular hulled (RH) barley was also included for comparison. Two diets containing 96.5% of either LP or RH barley, 2.5% trace minerals and vitamins and 1% indigestible marker (Celite) were fed in a twoperiod change-over design. Each experimental period lasted 9 d; a 5-d acclimatization period followed by 2 d of fecal and 2 d of ileal digesta collection. Standardized ileal digestibility (SID) of amino acids (AA) was calculated using published values for ileal endogenous AA losses from our laboratory. Total phosphorus (as is) was similar in LP and RH; however, LP had lower phytate phosphorus (0.6 vs. 2.3, g kg (1 ) than RH. Apparent digestibility of phosphorus was higher (PB0.01) for LP barley than RH at both ileal (45 vs. 24%) and faecal (55 vs. 32%) levels. Compared with RH, LP had higher (PB0.05) DE and SID contents of all indispensable AA except Phe. In summary, a hulless low-phytate barley sample fed to finishing pigs had higher digestible phosphorus, energy and AA contents than regular hulled barley, indicating that use of hulless low-phytate barley in swine diets may have ecological benefit. Chaque pe´riode durait 9 jours, soit 5 jours d'acclimatation suivis de 2 jours de collecte d'e´chantillons fe´caux et de 2 jours de pre´le`vements d'e´chantillons des digest de l'ile´on. Les auteurs ont calcule´la digestibilite´uniformise´e des acides amine´s (AA) dans l'ile´on (DUI) a`partir des pertes endoge`nes d'AA dans l'ile´on e´tablies au laboratoire des auteurs. La concentration de phosphore total (tel quel) est similaire pour l'orge FTP et OO, cependant, le premier renferme moins de phytate du phosphore que le second (0,6 c. 2,3 g par kg). La digestibilite´apparente du phosphore est plus e´leve´e (PB0,01) chez l'orge FTP que chez l'orge OO, tant dans l'ile´on (45 c. 24%) que dans les fe`ces (55 c. 32%). Comparativement a`l'orge OO, l'orge FTP se caracte´rise par une plus grande (PB0,05) e´nergie digestible et DUI des AA essentiels, sauf la Phe. En re´sume´, l'orge a`grains nus et a`faible concentration de phytate servie aux porcs de finition contenait plus de phosphore, d'e´nergie et d'AA digestibles que l'orge ordinaire, signe que le premier pourrait avoir une certaine utilite´e´cologique dans les rations des porcs.

“…In wheat, lowest SID values are generally observed for lysine (Pedersen et al, 2007;Hennig et al, 2008), but also for threonine (Widyaratne and Zijlstra, 2007b). The low SID of lysine has been attributed to its relatively low content compared to the other AA in wheat (Fan et al, 1993).…”

“…The database A database containing AID of CP and AA in 38 barley samples for pigs was extracted from a total of 26 peer-reviewed papers with data on AID of CP and AA in barley including studies of Baidoo and Liu (1998) (3);De Lange et al (1990) (1); Fan et al (1993) (1); Fan and Sauer (1995) (1); Fan and Sauer (2002) (6); Fernández-Fígares et al (2008) (1) ;Fuller et al (1994) (1); Furuya and Kaji (1991) (1); Green et al (1987) (1); Ige et al (2010) (2); Jørgensen et al (1997) (2); Lin et al (1987) (1); Nitrayová et al (2006) (1); Nyachoti et al (1997) (1); Pedersen et al (2007) (1); Perttilä et al (2002) (1); Reverter and Lindberg (1998) (1); Rowan and Lawrence (1986) (1); Sauer et al (1977) (1); Sauer et al (1981) (4); Schröder et al (1989) (1); Stein et al (1999) (1); Taverner et al (1981b) (1); Yin et al (1993) (1); Yin et al (2001a) (1) and Yin et al (2002) (1) (number of barley samples per study is given in brackets). The selection of these peer-reviewed papers was based on several criteria including (1) complete information on diet composition; (2) complete information on CP and AA contents of the diet and (or) barley; (3) use of barley as the only source of protein in the diet; (4) diets being devoid of feed additives.…”

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...
