Abstract It is hypothesized that heat processing may increase P digestibility in different protein sources fed to growing pigs. A study was conducted to determine the apparent total tract digestibility (ATTD) and standardized total tract digestibility (STTD) of P in soybean expeller (SBE) produced from oil extraction using dry extrusion and expelling and to investigate the effects of heat treatment on the ATTD and STTD of P in SBE, canola meal (CM), and canola expeller (CE) fed to growing pigs. Thirty-six growing barrows with an initial body weight of 19.0 ± 1.0 kg (mean ± SD) were assigned to 1 of 6 experimental diets in a completely randomized design to give 6 replicates per diet. The experimental design was a 3 × 2 factorial arrangement including three oilseed meals with or without heat treatment. The diets were formulated to contain non-autoclaved or autoclaved (at 121°C for 60 min) SBE, CM, and CE as the sole source of P. Limestone was included in diets to maintain a Ca:total P ratio of 1.3:1 across diets. Pigs were individually housed in metabolism crates for 12 days, including 7 days for adaptation and 5 days for total collection of feces. Pigs were offered their daily ration at 2.8 times their maintenance energy requirement. Data were analyzed using the PROC MIXED of SAS. Heat treatment increased (P < 0.05) the ATTD and STTD of P. Pigs fed the SBE diets had greater (P < 0.05) ATTD and STTD of P than pigs fed CM and CE diets. For the autoclaved ingredients, the values of STTD of P were 49.4, 23.2, and 25.8% for SBE, CM, and CE, respectively, whereas STTD of P in non-autoclaved SBE, CM, and CE were 48.5, 20.2, and 22.5%. Heat treatment increased (P < 0.05) the ATTD of Ca. In conclusion, heat treatment increased ATTD and STTD of P and ATTD of Ca in SBE, CM, and CE fed to growing pigs. The ATTD and STTD of P in SBE determined in the current study were 41.0 and 48.5%, respectively.

Abstract Although heat treatment affects digestibility of amino acids in feed ingredients, there is less information as to whether such an effect also applies to minerals. Therefore, the objective of this research was to investigate the effects of heat treatment on apparent (ATTD) and standardized total tract digestibility (STTD) of P in dry extruded-expelled soybean meal (DESBM), solvent-extracted canola meal (SCM), and expeller-extracted canola meal (ECM) fed to growing pigs. A total of 36 pigs (19.0 ± 1.0 kg) were assigned to 1 of 6 diets in a completely randomized design to give 6 replicates per diet. Pigs were individually housed in metabolism crates for 12 d, including 7 d for adaptation and 5 d for total collection of feces. The experimental diets were formulated to contain non-heated or heat-treated DESBM, SCM, and ECM as the sole source of P. Pigs were offered their daily ration at 2.8 times their maintenance energy requirement. Data were analyzed as a 3 × 2 factorial arrangement using the PROC MIXED of SAS with ingredients, heat treatment, and their interaction; however, no interaction was observed for any variable. Pigs fed the DESBM diet had a higher (P < 0.05) ATTD and STTD of P than pigs fed SCM and ECM diets. The ATTD and STTD of P in heat treated samples were higher (P < 0.05) than in non-heated samples. In the heat-treated samples, the values of STTD of P were 49.4, 23.2, and 25.8% for DESBM, SCM, and ECM, respectively. Respective values for STTD of P in non-heated DESBM, SCM, and ECM were 48.5, 20.2, and 22.5%. The ATTD of Ca in non-heat-treated samples was lower (P < 0.05) compared to the values for heat-treated samples. In conclusion, heat treatment increased ATTD and STTD of P in DESBM, SCM, and ECM fed to growing pigs.

Background: The addition of synthetic methionine to growing pig diets should consider the requirements of the methionine+cysteine complex, as most cysteine is obtained through dietary methionine. Objective: To determine an optimal level of methionine+cysteine (Met+Cys) in growing pig diets. Methods: Ninety-nine hybrid (Yorkshire×Landrace×Duroc) barrows were used in a completely randomized design (initial body weight: 25.90±3.99 kg). Nine levels of Met+Cys (0.500, 0.525, 0.550, 0.575, 0.600, 0.625, 0.650, 0.675, and 0.700%) were evaluated during 35 days. To determine a multi-objective optimal level of Met+Cys, growth performance and strongly related carcass traits were evaluated. Results: Average daily feed intake (ADFI) and feed:gain ratio (FGR) showed a linear response to the dietary Met+Cys level (p<0.05), with estimated optimal concentration at 0.700%. Average daily gain (ADG) did not show any effect on the Met+Cys level (p>0.05). Carcass characteristics were not affected by the Met+Cys concentration (p>0.05). The multi-objective optimal level for ADG, ADFI, and FGR was 0.667% Met+Cys. Conclusions: According to our results, 0.667% Met+Cys is the best concentration in diets for growing pigs.

Abstract The objective of this research was to estimate the apparent (ATTD) and standardized (STTD) total tract digestibility of phosphorus (P) in high-protein sunflower meal (HP-SFM) fed to growing pigs with or without phytase supplementation. Twenty-four individually-housed pigs (19.5 ± 1.9 kg) were assigned to 1 of 4 diets in a completely randomized design to give 6 replicates per diet. The experimental diets consisted of a corn-soybean meal-based basal diet and a diet containing 30% of HP-SFM, both of which were fed without or with phytase supplementation at 500 phytase units/kg. Pigs were given their daily feed allowance at 2.8 times the maintenance energy requirement. The experimental period lasted for 15 d including 10 d for adaptation to experimental diets and 5 d for total collection of feces. The STTD of P was calculated by correcting the ATTD of P with the basal endogenous P loss, which was assumed to be 190 mg/kg dry matter intake. Phytase supplementation decreased (P &lt; 0.05) both calcium (Ca; 1.34 vs. 2.14%) and P concentrations in feces (3.23 vs. 4.44%) in HP-SFM including diets. Addition of dietary phytase to the HP-SFM-contained diets also reduced (P &lt; 0.05) daily Ca output from 3.08 to 1.86 g/d and daily P output from 6.41 to 4.51 g/d. The ATTD of Ca and P and STTD of P increased (P &lt; 0.05) by providing phytase in both basal and HP-SFM including diets. The ATTD and STTD of P in HP-SFM were 18.4 and 19.3% for without phytase and 36.5 and 37.5% for with phytase, respectively, and there was a tendency (P = 0.063) for phytase supplementation to increase P utilization in HP-SFM fed to growing pigs. The standardized total tract digestible P content in HP-SFM was calculated at 3.61 g/kg.

Abstract Two experiments were conducted to determine the influence of sources or concentrations of dietary fiber in nitrogen-free diets (NFD) on basal ileal endogenous losses (BEL) of amino acids (AA) and subsequent standardized ileal digestibility (SID) of AA in feed ingredients for pigs derived from such BEL. In Exp. 1, 20 pigs (initial body weight = 46.5 ± 2.97 kg) were assigned to five diets in a quadruplicate 5 × 2 incomplete Latin square design with two periods. Three NFD containing cellulose (insoluble and fermentable fiber), inulin (soluble and fermentable fiber), or carboxymethyl cellulose (CMC; soluble and non-fermentable fiber) at 40 g/kg plus two diets containing soybean meal (SBM) or wheat distillers’ dried grains (WDDG) as the sole source of nitrogen were prepared. Pigs fed NFD containing CMC had greater (P &lt; 0.05) BEL of AA, except for Arg and Pro, than those fed the other NFD. The SID of most AA in SBM and WDDG corrected by BEL of AA from NFD containing CMC were greater (P &lt; 0.05) than those corrected by BEL of AA from the other NFD. Experiment 2 was conducted with 21 barrows (initial body weight = 34.1 ± 2.57 kg) assigned to seven diets in a triplicate 7 × 3 incomplete Latin square design with 3 periods. Seven diets consisted of three NFD containing 4, 8, or 12 g/kg cellulose and four diets containing corn, wheat, SBM, or canola meal as the sole source of nitrogen. There was no difference in the BEL of AA, except for Pro, among pigs fed NFD with increasing concentration of cellulose. The SID of AA in test ingredients were not affected by BEL of AA from NFD containing increasing concentration of cellulose. In conclusion, chemical characteristics of dietary fiber, but not concentration, affect the BEL of AA in pigs.

Abstract Two experiments were conducted to test the hypotheses that pentoses absorbed from the small intestine of pigs reduce energy utilization and that pentoses that reach the hindgut are fermented. In Exp. 1, 24 barrows (9.95 ± 0.51 kg) with a T-cannula in the distal ileum were allotted to a completely randomized design with 3 diets that contained 15% glucose, 15% xylose, or 15% arabinose. Ileal digesta, feces, and urine were collected from all pigs. Data were analyzed via ANOVA using the Proc Mixed Procedure of SAS. No differences among diets were observed for apparent total tract digestibility of GE or for DE, but ME in xylose and arabinose diets was reduced (P < 0.01) compared with the glucose diet (Table 1) indicating that xylose and arabinose that are absorbed from the small intestine are excreted in the urine. In Exp. 2, 21 barrows (18.02 ± 1.1 kg) were allotted to a completely randomized design with 3 treatments and 7 pigs per treatment. A diet based on corn starch, casein, and 15% glucose was fed for 11 d. On d 4 through 11, saline, xylose, or arabinose (3% of the daily feed) was infused into the cecum of pigs via an ileal cannula, and feces and urine were collected. Data were analyzed as in Exp. 1. Infused xylose or arabinose was not detected in feces of the pigs infused with pentoses indicating that pentoses are fully fermented in the hindgut (Table 1). In conclusion, dietary free pentoses are absorbed prior to the end of the small intestine, but partially excreted in the urine, and therefore may reduce energy utilization. If pentoses are liberated in the hindgut, they may contribute to the energy status of the pig by being fermented with a subsequent absorption of short chained fatty acids.

Abstract Two experiments were conducted to test the hypothesis that standardized total tract digestibility (STTD) of Ca and the response to microbial phytase is constant among different sources of Ca carbonate and that the STTD of Ca is constant among different sources of dicalcium phosphate (DCP) when fed to growing pigs. In Exp. 1, 80 pigs (initial BW: 19.0 ± 1.9 kg) were randomly allotted to 10 diets and 2 blocks with 4 pigs per diet in each block. Four sources of Ca carbonate were used, and each source was included in a diet without microbial phytase and a diet with microbial phytase (500 units/kg diet). Two Ca-free diets without or with microbial phytase were also formulated. Feed allowance was 2.7 times the maintenance energy requirement for ME and daily feed allotments were divided into 2 equal meals. The initial 4 d of each period were considered the adaptation period to the diets followed by 4 d of fecal collection using the marker-to-marker procedure. Pigs fed diets containing exogenous phytase had lower (P < 0.05) basal endogenous loss of Ca compared with pigs fed diets containing no phytase. There were no interactions between phytase and source of Ca carbonate. Values for STTD of Ca were greater (P < 0.05) for diets containing microbial phytase (77.3% to 85.4%) compared with diets without exogenous phytase (70.6% to 75.2%), and values for STTD of Ca differed (P < 0.05) among the 4 sources of Ca carbonate. In Exp. 2, 40 pigs (initial BW: 14.9 ± 1.3 kg) were allotted to a completely randomized design with 5 diets and 8 replicate pigs per diet. A basal diet in which all Ca was supplied by Ca carbonate was formulated. Three diets were formulated by adding 3 sources of DCP to the basal diet and a Ca-free diet was also used. Feeding and collection methods were as described for Exp. 1. Results indicated that values for STTD of Ca and ATTD of P were not different among diets, indicating that under the conditions of this experiment, the digestibility of Ca and P in DCP appears to be constant regardless of origin of DCP. In conclusion, use of microbial phytase reduces the basal endogenous loss of Ca and increases Ca digestibility in Ca carbonate. The STTD of Ca varies among sources of Ca carbonate, regardless of phytase inclusion, but that appears not to be the case for the STTD of Ca in different sources of DCP.

ABSTRACTExperiments involving both digestion and growth trials were undertaken to compare the responses of pigs to two increments of digested energy resulting either from gut fermentation or from digestion by endogenous enzymes in the small intestine. Unmolassed sugar-beet pulp (SBP) and maize starch (MS) were selected as model materials for these two systems. A control diet was formulated to fulfil the needs of pigs for all essential nutrients apart from energy. This diet was offered according to a scale set at about twice the maintenance energy requirement. The two SBP diets contained 150 and 300 g SBP per kg (SBP15 and SBP30) and the two MS diets 100 and 200 g MS per kg (MS10 and MS20). Sixty observations were made with 10 female and 20 male growing pigs to provide information on digestion. The results showed that the energy in SBP and MS had an apparent digestibility of 0·74 and 0·98 respectively (s.e.d. 0025). The neutral-detergent fibre fraction of SBP had a digestibility of 0·81 (s.e. 0·055). Forty pigs (20 male and 20 female) were involved in the growth trial. The responses of pigs to increments of different digestible energy (DE) were measured in terms of daily carcass-weight gain. The results gave values of 435, 478, 527, 511 and 567 (s.e.d. 17·3) g/day for the control, SBP15, SBP30, MS 10 and MS20 treatments respectively. These results suggest that the apparent DE of SBP is used for carcass growth with an efficiency of 0·57 (s.e. 0·012) relative to the DE from MS.

Almeida, F. N., Htoo, J. K., Thomson, J. and Stein, H. H. 2013. Amino acid digestibility in camelina products fed to growing pigs. Can. J. Anim. Sci. 93: 335–343. Camelina seed production has increased in North America because of demand for camelina oil for biofuel production. Camelina expellers (CE) is the co-product that remains after oil has been expelled, and CE usually contains approximately 35% crude protein (CP), 14% ether extract, 10% crude fiber, and 5% ash making it an attractive feedstuff for livestock. An experiment was conducted to determine the standardized ileal digestibility (SID) of CP and amino acids (AA) in two sources of camelina seeds [CS-1 and CS-2; average: 39% acid hydrolyzed ether extract (AEE), 28% CP, 27% neutral detergent fiber (NDF), 12% acid detergent fiber (ADF), 4% ash] and in three sources of CE (CE-1, CE-2, and CE-3; average: 35% CP, 24% NDF, 15% AEE, 14% ADF, 6% ash) and to compare the SID of CP and AA in camelina products with the SID of CP and AA in solvent-extracted canola meal fed to pigs. Seven growing pigs (initial BW 43.5 kg) were randomly allotted to a 7×7 Latin square design with seven diets fed to individually housed pigs over seven periods. Six of the diets contained CS, CE, or canola meal as the sole source of CP and AA and a N-free diet was used to determine basal endogenous losses of CP and AA. The SID of CP in CS-1 and CE-2 was less (P<0.01) than the SID of CP in canola meal, but the SID of CP in CS-2, CE-1, and CE-3 was not different from the SID of CP in canola meal. The SID of Lys in CS-1 and CS-2 was less (P<0.01) than in canola meal, but the SID of Lys was not different among CE-1, CE-2, CE-3, and canola meal. Results from this experiment indicate that the SID of AA in CE is mostly comparable with that of canola meal, but the digestibility of CP and AA in the two camelina seeds was somewhat less than in CE and canola meal. Camelina expellers may, therefore, be included in diets fed to pigs.

Objective. Determine the nutritional values of ground (SCI) or extruded (SCE) canola seed and evaluate its use in the performance of piglets from 15 to 30 kg. Materials and methods. Two experimental diets with canola seed were evaluated in a digestibility trial. We used 15 barrows with an initial weight of 19.79±1.43kg, distributed in a completely randomized design. In the performance, four experimental diets were evaluated consisting of a diet with soybean oil added (RAS), one with the of addition of canola oil (RAC) and two oil-free; one with 11% SCI included and one with 6% SCE (RSCE) included. 40 commercial hybrid piglets were used that had 15.25±1.5kg initial body weight, randomly distributed, in four treatments and five replicates; two animals per experimental unit. Results. The digestible energy values for SCI and SCE were 4.197 kcal/kg and 5.234 kcal/kg, respectively. The extrusion process improved the digestibility coefficients. Piglets fed with RSCI showed less daily weight gain (DWG) and F:G ratio. Conclusion. Results suggest that SCE can be included in diets of piglets from 15 to 30 kg until 6% without negatively affecting performance.Key words: Animal performance, anti-nutritional factors, digestibility, economic viability (Source: AGROVOC).
