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< 0.01). The AID of amino acids (AA) was also improved (P< 0.05). Apparent total tract digestibility (ATTD) was increased by pelleting in DM, CP and DE by 5, 7 and 6% respectively (P< 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< 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.

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 < 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 < 0.05 and P < 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.

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 An experiment was conducted to test the hypothesis that a preparation of isoquinoline alkaloids (IQ) obtained from Macleaya cordata and added to corn-soybean meal diets increases the apparent ileal digestibility (AID) of amino acids (AA), crude protein (CP), starch, and acid hydrolyzed ether extract (AEE) when fed to young growing pigs. Thirty-two ileal cannulated barrows (initial body weight = 12.19 ± 1.38 kg) were allotted to a randomized complete block design with four diets and eight replicate pigs per diet. Diets were supplemented with 0, 90, 180, or 360 mg/kg IQ and with 0.40% chromic oxide. Diets were fed for 27 d and ileal digesta were collected on days 13 and 14 (period 1) and on days 26 and 27 (period 2). Effects of IQ inclusions were analyzed using contrast statements, and differences between periods were analyzed using a repeated measures statement. A quadratic increase (P &lt; 0.05) in the AID of Thr, Trp, Val, Pro, and Tyr was observed in period 1 as IQ was included in the diets, and AID of CP, Arg, His, Ile, Leu, Met, Phe, Thr, Trp, Val, Pro, and Tyr was greater in period 2 than in period 1 (P &lt; 0.05). In period 1, a quadratic increase (P &lt; 0.05) was observed for the AID of starch as IQ increased in the diet, but the AID of starch was less (P &lt; 0.05) in period 2 than in period 1. No differences among treatments or periods were observed for AID of AEE. Results indicate that inclusion of approximately 90 mg/kg of IQ in diets for weanling pigs may increase the AID of starch and some AA.

Abstract An experiment was conducted to determine if the inclusion of a preparation of isoquinoline alkaloids (IQ) in corn-soybean meal diets fed to finishing pigs increases the apparent ileal digestibility (AID) of amino acids (AA) and crude protein (CP) and the apparent total tract digestibility (ATTD) of CP and gross energy. Twelve ileal cannulated barrows (BW: 77.2 ± 6.23 kg) were allotted to a triplicated 4 x 3 incomplete Latin square design with 4 diets and 9 replicates per diet. Diets were supplemented with either 0, 40, 80, or 160 mg/kg IQ and with 0.40% titanium dioxide as an indigestible marker. Each collection period lasted 14 d with d 1 through 10 as an adaptation to the diets, fecal samples were taken using the grab sampling technique on d 11 and 12, and ileal digesta were collected for 8 h on d 13 and 14. Data were analyzed using the Proc MIXED procedure of SAS. Contrast statements were used to determine linear and quadratic effects of including IQ in the diets. Results were considered significant at P ≤ 0.05 and considered a trend at 0.05 &lt; P ≤ 0.10. Inclusion of IQ resulted in a quadratic increase (P &lt; 0.05) in the AID of CP and AA in corn-soybean meal diets fed to finishing pigs, with the greatest digestibility values generally observed in the 40 mg/kg IQ treatment. Additionally, IQ resulted in a quadratic increase (P = 0.009) in the ATTD of CP, with the greatest digestibility observed in the 80 mg/kg IQ treatment. Therefore, it was concluded that supplementing corn-soybean meal diets with 40 or 80 mg/kg IQ may increase the AID of CP and AA and ATTD of CP by finishing pigs.

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. Key words: Amino acids, digestibility, pigs, spray dried plasma protein, yeast extract

Abstract Two experiments were conducted to evaluate the digestible energy (DE), metabolizable energy (ME), and standardized ileal digestibility (SID) of amino acids (AA) in dried yeast (DY) and soybean meal (SBM) fed to pigs. In Exp. 1, 30 barrows with an initial body weight (BW) of 20.7 ± 1.01 were assigned to 5 diets in a randomized complete block design with period and BW as blocking factors. A basal diet was prepared to contain corn, canola meal, and soybean oil as energy-contributing ingredients. Four additional diets were prepared by adding 5 or 10 g/kg DY or SBM at the expense of energy-contributing ingredients in the basal diet to estimate the DE and ME in test ingredients by regression analysis. On a dry matter basis, estimated DE and ME in DY were 4,022 and 3,352 kcal/kg, respectively, and those in SBM were 3,876 and 3,601kcal/kg, respectively. There was no difference in estimated DE or ME between DY and SBM. In Exp. 2, 21 barrows (initial BW = 20.0 ± 1.31 kg) surgically fitted with T-cannulas at the distal ileum were assigned to 3 diets in a randomized complete block design with BW as a blocking factor. Two diets were prepared to contain DY or SBM as the sole source of nitrogen, and a nitrogen-free diet was prepared to determine the basal ileal endogenous losses of AA. The SID of AA, except for Gly and Pro, in SBM were greater (P &lt; 0.05) than in DY. The SID of indispensable AA in DY ranged from 64.7% for Thr to 86.1% for Arg, whereas those in SBM ranged from 84.8% for Thr to 92.3% for Arg. In conclusion, energy values in DY was comparable with SBM, but the SID of most AA in DY were less than in SBM.

Ileal digestibility of protein and amino acids was measured in pigs fed 13 round, tannin-free peas samples and related to the following physical, chemical and biological characteristics of these samples: thousand-seed weight, proportion of hulls, starch, fibre, crude protein, ether extract and ash contents, trypsin inhibitor activity and trypsin inhibitor activity per unit of crude protein (TIAP). Each pea sample was included in a diet containing starch, sucrose, minerals and vitamins and fed to four barrows (50 to 100 kg) fitted with an end-to-end ileo-rectal anastomosis. Standardised ileal protein and amino acid digestibilities, except for alanine of peas decreased linearly with increasing TIAP (P < 0.01) and was not affected by fiber content. For example standardized ileal digestibilities values (%) decreased by −0.1975, −0.1617, −0.2171, −0.2630, −0.2029 and −0.3536 per unit of TIAP (expressed in unit of trypsin inhibited per milligram crude protein), respectively, for crude protein and lysine, threonine, methionine, cystine and tryptophan.
