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.

The Difference

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.

Abstract Two experiments were conducted to test the hypothesis that standardized ileal digestibility (SID) of AA by growing pigs is not influenced by dietary AA. In Exp. 1, thirty cannulated pigs (BW:31.4 ± 3.9 kg) were allotted to 5 diets. Four diets were formulated to contain 4.7 to 30.4% CP, by including 10, 30, 50, or 70% soybean meal. An N-free diet was used to determine the basal endogenous losses of CP and AA. The model included diet as a fixed variable and polynomial contrasts were used to test linear and quadratic effects of dietary AA. The SID of CP, Lys, Phe, and Thr decreased linearly (P < 0.05) as dietary AA increased (Table 1). However, this effect was primarily a result of the SID of AA in the diet containing 30.4% CP and the SID of CP and most AA was not affected by dietary AA if diets contained 4.7 to 22.1% CP. In Exp. 2, twenty-four cannulated pigs (BW:22.8 ± 1.7 kg) were used. Pigs were allotted to a quadruplicated 6 × 2 Youden square design with 6 diets and 2 periods. Five diets were formulated to contain 6.8 to 31.8% CP, by including 10, 20, 30, 40, or 50% soy protein concentrate. An N-free diet was also used. Data were analyzed as for Exp. 1. The SID of His and Lys decreased quadratically (P < 0.05) with increased dietary AA (Table 2). However, if dietary CP was 26.6% or less, no effect of dietary AA on SID of CP and most indispensable AA was observed. In conclusion, the SID of most AA is not influenced by dietary AA if dietary CP does not exceed around 26%. Hence, the SID of AA in feed ingredients may be determined in diets containing AA below, at, or slightly above requirements without impacting results.

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 Soybean expellers may be produced by dry extrusion and mechanical oil pressing of soybeans, but there is limited information about the nutritional value of expellers produced via this procedure. Therefore, 2 experiments were conducted to test the hypothesis that standardized ileal digestibility (SID) of CP and amino acids (AA), apparent total tract digestibility (ATTD) of energy and total dietary fiber (TDF), and concentrations of DE, ME, and NE are greater in soybean expellers than in soybean meal (SBM) when fed to growing pigs. Pigs were the offspring of Line 359 boars mated to Camborough females (Pig Improvement Company, Hendersonville, TN). In experiment 1, nine growing barrows (initial BW: 55.98 kg ± 13.75 kg) with T-cannulas installed in the distal ileum were allotted to 1 of 3 diets using a triplicated 3 × 3 Latin square design with 3 periods. Two diets were formulated to contain 35% soybean expellers or 33% SBM as the sole source of AA. A N-free diet was used to determine basal endogenous losses of AA. Ileal digesta were collected on days 6 and 7 of each 7-d period. Results indicated that the SID of most indispensable and dispensable AA were greater (P &lt; 0.05) or tended (P &lt; 0.10) to be greater in soybean expellers than in SBM. In experiment 2, a corn-based diet and 2 diets based on corn and each of the 2 soybean products were formulated. Twenty-four growing barrows (initial BW: 44.88 kg ± 2.17 kg) were allotted to 1 of the 3 diets with 8 pigs per diet. Urine and fecal samples were collected for 4 d after 5 d of adaptation. Results indicated that the ATTD of energy and TDF was not different between soybean expellers and SBM, but the ATTD of TDF in the 2 soybean products was greater (P &lt; 0.05) than in corn. Concentrations of DE and ME in soybean expellers were greater (P &lt; 0.05) compared with corn or SBM. Soybean expellers had greater (P &lt; 0.05) calculated NE compared with SBM, but there was no difference in NE between corn and soybean expellers. In conclusion, values for SID of most AA and DE, ME, and NE in soybean expellers were greater than in SBM.
