“…In the current experiment, AID for DM consistently had a higher value in treatment groups consuming enzyme-supplemented diets. This is partially consistent with that of Mok et al (2013). They have reported improvements in AID values for DM, CP and GE when β-mannanase was supplemented to diets containing palm kernel expeller.…”

“…The efficacy of β-mannanase on AID of N and energy in the current study might have been influenced by the low quality of SBM because both SBM sources had TI at the level higher than accepted level. Mok et al (2013) have noted that β-mannanase supplementation in a diet based on corn, soybean meal and palm kernel expellers could increase the AID of leucine and phenylalanine when given to growing pigs. The increase in AID of these amino acids was explained by the availability of higher mannan content in palm kernel expeller, which is a substrate for β-mannanase.…”

Apparent ileal digestibility (AID) of energy, dry matter (DM), nitrogen (N) and amino acids and standardized ileal digestibility (SID) of amino acids in low quality soybean meals with different CP concentration (SBM 44% CP and SBM 48% CP) with or without 400 U β-mannanase/kg supplementation were evaluated in 20 cannulated barrows ((Landrace × Yorkshire) × Duroc) with an average BW of 25.08 ± 3.42 kg. A N-free diet was used to determine basal endogenous losses of amino acids. The supplementation of β-mannanase improved ( P < 0.05) AID of DM compared with non-supplemented diet. However, enzyme supplementation did not improve ( P > 0.05) AID of N and energy. The type of SBM (SBM 44% CP v. SBM 48% CP) had no effect on AID of DM, N and energy. β-mannanase improved (P < 0.05) AID of sum of essential amino acids, arginine, histidine, lysine, valine and glycine. The SID of lysine was higher ( P < 0.05) in enzyme supplemented than in non-supplemented diets. Larger AID and SID of threonine and proline ( P < 0.05) were observed in SBM 48% CP than in SBM 44% CP. In conclusion, the supplementation of enzyme improved AID of arginine, histidine, lysine, valine and glycine, but it did not cause marked difference in SID of these amino acids except for lysine. The low nutrient digestibility of the SBM sources used in the present experiment might have favoured the positive effect of β-mannanase supplementation.Keywords: amino acid, ileal digestibility, mannanase, pig, soybean meal Implications Soybean meal (SBM) has been considered to be the most important plant-based protein source in livestock nutrition. However, the presence of anti-nutritional compounds such as trypsin inhibitor, lectins, non-starch polysaccharide in soybeans adversely affects their nutrient digestibility and absorption. In this study, feeding the diet supplemented with β-mannanase improved apparent ileal digestibility (AID) of dry matter, sum of essential amino acids, arginine, histidine, lysine, valine and glycine and the standardized ileal digestibility of lysine. Regarding SBM types, both SBMs had similar AID values for most of the nutrients except threonine and proline, which had higher AID values in SBM 48% CP. Results from this study indicate that the low digestibility of SBM might have favoured the positive effect of β-mannanase supplementation.

“…Palm Kernel Expellers (PKE) has recently received great attention because of the low price compared with other ingredients (Kim et al, 2001;Fang et al, 2007;Son et al, 2012). However, the content of mannan in PKE was much greater than that in other ingredients widely used for swine diets (Table 1; Mok et al, 2013). Table 1.…”

“…Enzyme complex of mannanase and cellulase effectively hydrolyzed the fiber components of PKE and the pretreating PKE with the enzyme complex resulted in improvement in the true metabolizable energy value of pre-treated PKE compared with the raw PKE in diets fed to broilers (Saenphoom et al, 2013). In pigs, β-mannanase improved apparent ileal and total tract digestibilities of Dry Matter (DM), organic matter and energy in diets containing 10% PKE fed to pigs (Mok et al, 2013). However, data on the dosedependent effects of β-mannanase on energy and mannan digestibility of PKE-containing diets are rare.…”

An experiment was conducted to determine the effects of various inclusion levels of β-mannanase on the energy and mannan digestibility in diets containing corn, Soybean Meal (SBM) and Palm Kernel Expellers (PKE) fed to growing pigs. The PKE contained 92.6% dry matter, 4,417 kcal gross energy kg −1 , 4.02% ash and 31.3% mannan on an as-fed basis. Six barrows with an initial body weight of 41.4±1.7 kg were individually housed in metabolism crates equipped with a feeder and a nipple drinker. Pigs were randomly allotted to a 6×6 Latin square design with 6 dietary treatments and 6 periods. An experimental period consisted of a 4-d adaptation period and a 5-d collection period. Pigs were fed corn-SBMbased diets containing 15% PKE with 0, 400, 800, 1,600, 2,400 or 3,200 U kg −1 of β-mannanase. A chromic oxide was added as an indigestible marker for fecal collection according to a marker-to-marker procedure. Urine was also collected from each period. Each of the 6 diets contained 3.60, 3.91, 4.06, 2.57, 3.57 and 2.59% of mannan, respectively. No linear and quadratic effects of β-mannanase supplementation on apparent total tract digestibility of energy were observed. The digestibility of mannan was also not affected by the increasing level of β-mannanase supplementation. In conclusion, exogenous β-mannanase did not affect the energy and mannan digestibility in corn-SBM-based diets containing 15% of PKE fed to growing pigs.

“…La energía metabolizable aparente (EMA) de la dieta se determinó al sustraer la EB de la orina de la EDA de la dieta (Mendoza et al 2010). Se implementó un periodo de adaptación de 5 días y 2 días de recolección heces y orina (Viljoen et al 1998;Mendoza et al 2010;Mok et al 2013;Zhou et al 2013). En el periodo de recolección se calculó el consumo de alimento y para tal fin se pesó el alimento ofrecido y el despreciado al final del periodo de recolección (Lammers et al 2008b).…”

Valoración de energía digestible de la glicerina cruda proveniente de aceite de palma -Elaeis guineensis-para cerdos en crecimiento en función del nivel de almidón de maíz en la dieta RESUMENPara determinar la energía digestible aparente (EDA) de la glicerina cruda (GC) proveniente del aceite de palma (Elaeis guineensis) en cerdos se realizaron dos experimentos (E). En E1 se determinó la EDA para GC con la técnica de la bolsa móvil de nailon (TBMN) utilizando ocho cerdos castrados con cánula duodenal. En E2 se determinaron la EDA y la energía metabolizable aparente (EMA) para GC, por el método convencional con indicador (MCI), con 10 cerdos castrados ubicados en jaulas metabólicas. En E1 y E2 se evaluaron, en un arreglo factorial 2 x 5, dos niveles de almidón de maíz (NA) en la dieta, 10% (NA10) y 12% (NA12), y cinco niveles de sustitución con GC (0%, 2,5%, 5,0%, 7,5% y 10%) en E1 en un diseño completo al azar y en E2 en un diseño de cuadrado latino. Para TBMN y MCI los datos se analizaron mediante regresión lineal múltiple y el metabolismo del nitrógeno en MCI como un diseño de cuadrado latino utilizando los módulos REG y GLM del paquete SAS. Por TBMN no hubo efectos (P > 0,05) del NA sobre la EDA de GC. La EDA de GC se calculó en 3.251 kcal/kg MS. La EDA de GC en MCI dependió de NA (P < 0,001) estimándose en 4.427,3 y 3.769,3 Kcal/kg MS para NA10 y NA12, respectivamente. Hubo interacción (P < 0,001) entre NA y GC para la cantidad de nitrógeno digestible, se redujo cuando GC aumentó en NA12 y aumentó en NA10. Otros parámetros del metabolismo nitrogenado no se vieron afectados (P > 0,05). Los resultados de EDA corregidos por NA con MCI mostraron correlación alta (R 2 = 0,82) con TBMN. Con MCI se pudo establecer que el aumento en NA en la dieta reduce la EDA de GC. Palabras clave: biodiesel, glicerina cruda, metabolismo energético, subproductos. VALUATION OF DIGESTIBLE ENERGY OF CRUDE GLYCERIN FROM PALM OIL -Elaeis guineensis-FOR GROWING PIGS BASED ON DIETARY CORN STARCH LEVEL ABSTRACTTo determine the apparent digestible energy (EDA) of crude glycerin (GC) from palm oil (Elaeis guineensis) in pigs two experiments (E) were performed. In E1, EDA was determined to GC, with the technique of mobile nylon bag (TBMN) using eight barrows with duodenal cannula. In E2, EDA, EMA to GC was determined by the conventional method with indicator (MCI) with 10 barrows placed in metabolic cages. In E1 and E2 were evaluated in 2 x 5 factorial arrangement, two levels of corn starch (NA) in the diet, 10 (NA10) and 12% (NA12), and five levels of replacement by GC (0%, 2.5%, 5%, 7.5% and 10%), in E1 as a completely randomized design and in E2 as a Latin square design. For MCI and TBMN, data were analyzed using multiple linear regression and nitrogen metabolism in MCI as a Latin square design using the GLM and REG modules of SAS. By TBMN there was no effect (P > 0.05) in the NA on the EDA of GC. EDA of G...
