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.

Abstract An experiment was conducted to test the hypothesis that spray dried plasma (SDP) increases the standardized ileal digestibility (SID) of CP and AA from other ingredients in diets for young pigs, which may result in a lack of additivity in such diets. Thirty ileal cannulated barrows (body weight: 9.30 ± 0.63 kg) were randomly allotted to a triplicated 10 × 3 Youden square design with 10 diets and three 7-d periods. Diets from four regions were formulated: the U.S.A. [corn-soybean meal (SBM)-based diet], the European Union (corn-wheat-barley-SBM-based diet), Canada (wheat-barley-SBM-fermented SBM-based diet), and Asia (corn-rice-SBM-fermented SBM-based diet). Diets from each region contained 0 or 6% SDP. Differences between measured and predicted SID of CP and AA in diets with SDP were calculated. Data were analyzed using PROC MIXED of SAS as a 2 × 4 factorial with 2 levels of SDP and 4 regions. There was an SDP by region interaction for the measured SID of CP and all AA, except Lys (Table 1). When SDP was added to the U.S.A, the European Union, and Asia diets, the SID of CP and AA was not increased. The SID of CP and AA, except Lys, was greater (P < 0.05) in the Canada diet with SDP than without SDP. The measured SID of CP and AA was consistent with predicted values for the European Union and Asia diets (Table 2). The measured SID of Trp was less (P < 0.05) than predicted for the U.S.A. diet, and the measured SID of CP and all indispensable AA was greater (P < 0.05) than predicted in the Canada diet. In conclusion, addition of 6% SDP to wheat-barley-based diets may increase SID of CP and AA, and therefore, the SID of CP and AA in diets containing SDP may be greater than predicted.

Abstract The objectives were to determine the digestible energy and standardized ileal digestibility of amino acids (AA; Exp. 1) and to determine growth performance (Exp. 2) of 2 sources of dietary spray-dried plasma protein (SDPP) in nursery pigs. In Exp. 1, twelve nursery barrows (9.8 ± 0.9 kg) were assigned to a quadruplicated 3 × 2 Latin square design with 3 diets and 2 periods. Each period consisted of 5 days of adaptation, 2 days of fecal sampling, and 2 days of ileal collection. A basal diet was composed of corn, soybean meal, whey, and sucrose as the sole energy and AA sources. Experimental diets were prepared by replacing 15% of the energy and AA sources in the basal diet with SDPP 1 (manufactured in the USA; 78.2% crude protein and 4,862 kcal gross energy/kg as-is) or SDPP 2 (manufactured in Korea; 74.3% crude protein and 4,636 kcal gross energy/kg as-is). Spray-dried plasma protein 1 had greater digestible energy (P < 0.05), but less (P < 0.05) standardized ileal digestibility of Lys, Met, Trp, and Thr compared with SDPP 2. In Exp. 2, eighty-four nursery pigs (7.9 ± 0.7 kg) were allotted to 3 dietary treatments in a randomized complete block design with 7 replicate pens and 4 pigs per pen. Three corn-soybean meal-whey-based diets contained fish meal (6% and 3.5% for d 0 to 14 and d 14 to 28, respectively), SDPP 1 (4.5% and 2.7%), or SDPP 2 (5.0% and 3.0%) to maintain same energy and nutrient concentrations. During d 0 to 14 and overall period, pigs fed the diets containing SDPP gained more weight (P < 0.05) than those fed the fish meal diet with no difference between 2 SDPP sources. In conclusion, SDPP 1 contains greater digestible energy but less AA digestibility compared with SDPP 2. Growth-promoting effects of both SDPP sources in nursery diets have been clearly demonstrated in this work.

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 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.

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.

Average Body

Studies were carried out with 12 pigs (Yorkshire × Landrace) to determine the effect of dietary fibre level on amino acid digestibility. The pigs were weaned at 21 d of age and fitted with a simple T-cannula at the distal ileum at 23 or 24 d of age. The pigs were fed four isonitrogenous corn starch-based soybean meal diets (22.5 % crude protein) containing 4.3, 7.3, 10.3 and 13.3% Solkafloc according to a balanced two-period change-over design. The pigs were fed four times daily, equal amounts, at 6-h intervals. The diets were supplied at a rate of 5% of the average body weight which was determined at the initiation of the first (8.8 kg) and second (11.7 kg) experimental period. Each experimental period comprised 10 d. Feces were collected for 48 h on days 6 and 7 and ileal digesta for 24 h during days 8, 9 and 10. Chromic oxide was used as digestibility marker. The dietary inclusion of Solkafloc, up to 13.3 %, did not affect (P > 0.05) the apparent ileal as well as the fecal digestibilities of crude protein and amino acids. In conclusion, starter pigs can tolerate up to 13.3% Solkafloc, equivalent to 16.8% neutral-detergent fibre, in corn starch-based soybean meal diets without a depression in amino acid digestibility.
