Abstract The objective was to test the hypothesis that there is no effect of origin or processing procedure on the standardized ileal digestibility (SID) of amino acids (AA) and crude protein (CP) in sunflower co-products. Six sources of sunflower meal (SFM) and 1 source of sunflower expellers (SFE) were obtained from Ukraine, Italy, Hungary, and the U.S. Each source of SFM or SFE was the only source of CP and AA in 1 diet and an N-free diet was also used for a total of 8 diets. Eight barrows (body weight: 28.5 ± 2.4 kg) had a T-cannula installed in the distal ileum and were allotted to 1 of the 8 diets using an 8 × 8 Latin square design with 8 periods. The Lys:CP ratio in the 6 sources of SFM ranged from 3.10 to 3.96% with CP concentrations ranging from 27.34 to 36.75%. Crude protein in SFE was 26.87% and the Lys:CP ratio was 3.51%. Concentrations of acid hydrolyzed ether extract in the 6 sources of SFM ranged from 0.60 to 3.11%, but SFE contained 8.77%. Results indicated that the SID of CP was lower (P < 0.05) in SFM from Hungary compared with all other sources of SFM except for 1 of the sources from Ukraine. There were no differences in the SID of Lys, Met, and Trp among sources of SFM, but for most of the remaining indispensable AA, the SFM from Hungary had less (P < 0.05) SID than the other sources. However, only few differences in SID of indispensable AA were observed among the other sources of SFM, but the SID of CP and all AA except Trp was greater (P < 0.05) in SFE compared with SFM. In conclusion, there were only few differences in the SID of the first limiting AA among SFM obtained from Ukraine, Hungary, Italy, and the U.S., but the SID of CP and AA was greater in SFE than in SFM indicating that processing of sunflower seeds influence the nutritional value.

Abstract AbstractThree experiments were conducted to test the hypothesis that standardized ileal digestibility (SID) of amino acids (AA), concentration of metabolizable (ME), and standardized total tract digestibility (STTD) of P in a new source of distillers dried grains with solubles (DDGS; ProCap DDGS) are greater than in conventional de-oiled DDGS. In experiment 1, nine barrows (initial BW: 67.2 ± 6.4 kg) with a T-cannula in the distal ileum were allotted to a triplicated 3 × 3 Latin square design with three diets and three periods for a total of nine replicate pigs per diet. Two diets included ProCap DDGS or de-oiled DDGS as the sole source of crude protein (CP) and AA. An N-free diet was used to determine the basal endogenous losses of CP and AA. Ileal digesta were collected on days 5 and 6 of each period after 4 d of adaptation to diets. Results from experiment 1 indicated that ProCap DDGS contained more CP and AA compared with de-oiled DDGS. The SID of all AA in ProCap DDGS was greater (P < 0.001) compared with de-oiled DDGS with the exception that the SID of Pro was not different between the two sources of DDGS. In experiment 2, 24 growing barrows (initial BW: 32.7 ± 3.1 kg) were housed individually in metabolism crates and used in a randomized complete block design and fed a corn-based diet or two diets containing corn and each source of DDGS with eight replicate pigs per diet. Fecal and urine samples were collected for 4 d after 7 d of adaptation. Results from experiment 2 indicated that concentration of ME in ProCap DDGS was greater (P < 0.05) compared with corn or de-oiled DDGS. In experiment 3, 32 growing barrows (initial BW: 20.2 ± 0.9 kg) were placed in metabolism crates and allotted to four diets with eight pigs per diet using a 2 × 2 factorial treatment arrangement. The de-oiled DDGS and ProCap DDGS were both included in a diet without microbial phytase and a diet with microbial phytase (500 units/kg diet). Pigs were adapted to the diets for 5 d and fecal samples were collected for 4 d. Results from experiment 3 indicated that inclusion of phytase in the diet containing ProCap DDGS increased (P < 0.05) the STTD of P, but addition of phytase to the de-oiled DDGS diet did not increase STTD of P (interaction, P < 0.001), but the STTD of P was greater (P < 0.05) in de-oiled DDGS compared with ProCap DDGS. In conclusion, ProCap DDGS has greater SID of AA and contains more ME, but has reduced STTD of P compared with conventional de-oiled DDGS.

Apparent ileal digestibility and standardised ileal digestibility of energy, dry matter, nitrogen and amino acids were evaluated in five cannulated [(Landrace × Yorkshire) × Duroc)] barrows with an initial bodyweight of 27.1 ± 0.58 kg in a 5 × 5 Latin square design. Pigs were fed unfermented soybean meal (USM) as control and fermented soybean meal A, B and C (FSMA, FSMB and FSMC, respectively), with 52.4%, 62.0% and 71.8% protein solubility, respectively, and a nitrogen-free diet. The nitrogen-free diet was used to determine basal endogenous losses of crude protein and amino acids. The apparent ileal digestibility of dry matter and nitrogen was greater (P < 0.05) in FMSC and tended to improve in FSMA and FSMB compared with the control. The apparent ileal digestibility of isoleucine, phenylalanine and valine was greater in all fermented soybean meal whereas that of lysine was greater (P < 0.05) in FSMC compared with USM. Likewise, the apparent ileal digestibility of aspartic acid and proline was greater (P < 0.05) in FSMA and FSMC. The standardised ileal digestibility of crude protein and lysine was higher (P < 0.05) in FSMC and tended to improve in FSMA and FSMB whereas the standardised ileal digestibility of isoleucine was higher (P < 0.05) in FSMA, FSMB and FSMC compared with USM. In conclusion, fermentation of soybean meal showed better digestibility compared with USM regardless of its protein solubility values.

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 This study was conducted to determine the effect of pelleting on the digestibility of corn-soybean meal-based diet in growing pigs. Two trials with 6 pigs cannulated at the distal ileum were conducted. In each trial, pigs were assigned to each treatment following a crossover design. In each experiment, the same diet, composed of corn and soybean meal with 10% wheat from two different feed mills, was served in pellet or mash form. Pelleting allowed an increase in digestibility in one of the trials. Apparent ileal digestibility (AID) of dry matter (DM), crude protein (CP) and digestible energy (DE) were improved with pelleting by 8, 12 and 9% (P&lt; 0.01). The AID of amino acids (AA) was also improved (P&lt; 0.05). Apparent total tract digestibility (ATTD) was increased by pelleting in DM, CP and DE by 5, 7 and 6% respectively (P&lt; 0.01). The digestibility of the mash diet in experiment 1 was lower than in the pelleted diet in the experiment 1 and both diets in experiment 2 as shown by the interaction Pelleting X Trial which was significant for the AID and ATTD of DM, CP and DE (P&lt; 0.01). Therefore, in experiment 1, pelleting allows to improve the digestibility of diet to the same level as in experiment 2. The AID of CP was higher by 37% in the mash diet from the second experiment compared to the one in the first experiment. Even though the same ingredients were chosen in the two experiments, this shows the variability in digestibility existing between different feed mills and ingredient sources. This difference was not observed in pelleted diets. The results obtained in these two trials show that pelleting can reduce the variability of digestibility and then give a good digestibility of diets even if the ingredients are of different quality or sources.

AbstractThe effects of xylanase and antibiotic addition to the diet, and the use of HCl-insoluble ash as a marker, on ileal and faecal apparent digestibilities of nutrients were studied with 12 growing pigs fitted with post-valvular T-caecum cannulae (PVTC). The results showed that the apparent ileal digestibility of non-starch polysaccharide (NSP) was high, (over 0·30). Xylanase, or antibiotics (Avoparcin) or xylanase plus antibiotics supplementation of the wheat middling-based diets did not significantly (P > 0·05) increase the ileal and faecal apparent digestibilities of NSP, neutral-detergent fibre (NDF), dry matter, crude protein, energy or amino acids. There were no significant (P > 0·05) differences between the HCl-insoluble ash and Cr2O3 recoveries at the ileal or at the faecal levels: proportionately, 0·864 and 0·911 for the ileal and faecal recoveries of HCl-insoluble ash, and 0·857 and 0. 915 for the ileal and faecal recoveries of Cr2O3, respectively.

Two growth experiments were conducted to determine the effect of heat on the utilization of ileal-digestible lysine from field peas (Pisum sativum cultivar Dundale) fed to growing pigs. Five lysine-deficient diets (0.36 g ileal-digestible lysine/MJ digestible energy (DE)) were formulated using raw field peas, and field peas heated to either 110°, 135°, 150°, or 165° for 15 min respectively in a forced-air dehydrator. Additional diets were formulated with supplements of free lysine to verify that lysine was limiting in the diets containing the raw peas, and peas heated to 150° or 165°. The growth performance and retention of ileal-digestible lysine by pigs given the diets was determined over the 20–45 kg growth phase. Heat had a significant quadratic effect (P < 0.01) on growth rate, with responses declining from 543 g/d with pigs given the raw peas, to 407 g/d for those given the peas heated to 165°. Similarly, crude protein deposition declined in a quadratic manner (P < 0.001) from 76 to 36 g/d for pigs fed on raw peas and peas heated to 165° respectively. Retention of ileal-digestible lysine was 0.85 in the pigs given the raw field peas and declined in a quadratic manner (P < 0.001) with the application of heat to 0.48 in those pigs given the peas heated to 165°. Pigs fed on field peas heated to 165° had increased (P < 0.05) liver weights. The results indicate that heat applied to protein concentrates, even at mild temperatures, renders lysine in a form that is apparently absorbed but inefficiently utilized by the growing pig. Consequently, ileal digestibility values for lysine in heat-processed meals are unsuitable for diet formulations.

The current study evaluated the influence of a multi-carbohydrase and phytase complex (MCPC) on the ileal and total tract digestibility of nutrients in growing pigs. A total of eight barrows (initial BW = 30.7 ± 1.1 kg) were surgically fitted with a T-cannula at the distal ileum and randomly allotted to four groups. The experiment was conducted according to a 4 × 4 Latin square design, each period lasting 10 days. Pigs were fed four experimental diets, which consisted of two basal diets (BD1, low phytate; BD2, high phytate) with or without MCPC containing at least 1800 U xylanase, 6600 U α-arabinofuranosidase, 1244 U β-glucanase, and 1000 U phytase per/kg corn–soybean meal with 15% corn distillers based diet. The high phytate diet reduced (p < 0.05) the apparent ileal digestibility (AID) of crude protein by 1.4% and the apparent total tract digestibility (ATTD) of organic matter, crude protein, and gross energy by 1.7, 2.3, and 1.9%, respectively, and tended to decrease (p = 0.10) the ATTD of Ca by 17.3%, relative to the low phytate diet. The dietary supplementation of the MCPC increased (p < 0.05) the AID of phosphorus (P) and calcium (Ca) by 34.2% and 31.1% for BD1 and 26.7% and 41.3% for BD2, respectively, and increased (p < 0.05) ATTD of crude fat, P, and Ca by 1.4%, 45.6%, and 9.6% for BD1 and 3.1%, 66.0%, and 52.7% for BD2, respectively. The MCPC supplementation did not significantly increase the AID and (or) ATTD of crude protein, organic matter, and starch. In conclusion, the dietary supplementation of the MCPC could improve the AID of P and Ca and the ATTD of crude fat, P, and Ca.

Abstract An experiment was conducted to test the hypothesis that values for standardized ileal digestibility (SID) of amino acids (AA) in corn, wheat, and wheat middlings obtained using the direct procedure are not different from values obtained using the difference procedure. Sixteen ileal-cannulated barrows (initial BW: 69.5 ± 5.0 kg) were allotted to a replicated 8 × 4 Youden Square design with 8 diets and 4 periods. Each period consisted of 5 d of adaptation to the diet and 2 d of collection of ileal digesta. Four diets were based on soybean meal (SBM), corn, wheat, or wheat middlings as the only AA-containing ingredients. Three additional diets were based on a mixture of SBM and corn, SBM and wheat, or SBM and wheat middlings, and an N-free diet was also used. The apparent ileal digestibility (AID) and the SID of crude protein (CP) and AA for the 4 diets containing SBM, corn, wheat, or wheat middlings as the sole source of AA were calculated using the direct procedure. The AID and SID of CP and AA for the 3 mixed diets containing SBM and corn, wheat, or wheat middlings were also calculated and the contribution of digestible AA from SBM was subtracted from the AID or SID values for the diets. The AID or SID of AA in corn, wheat, and wheat middlings were subsequently calculated by difference. Results indicated that the AID values for a few AA were lower (P &lt; 0.05) if the direct procedure was used instead of the difference procedure, regardless of ingredient. The AID of Trp was greater in corn and wheat middlings, and the SID of Trp in corn and wheat middlings tended to be greater, if the direct procedure rather than the difference procedure was used, but that was not the case for wheat (interaction, P &lt; 0.05 and P &lt; 0.10, respectively). However, for all other indispensable AA, and for most of the dispensable AA, the SID of AA in corn, wheat, and wheat middlings was not different between the difference procedure and the direct procedure. Therefore, values for SID of AA in cereal grains and fiber-rich ingredients may be determined using either the direct or the difference procedure.
