Protein Supplements

Two experiments were conducted to evaluate rapeseed meal (RSM) produced from seed of Brassica campestris L. ’Candle’ in comparison with B. napus L. ’Tower’, soybean meal and fababeans (Vicia faba) as protein supplements for growing swine. In experiment 1 Candle RSM (5, 10 or 15%) was substituted for soybean meal or fababeans in barley- and wheat-based diets for 120 pigs from 23 to 88 kg liveweight. The effects of supplementary iodine (0.14 mg I/kg diet) and amino acids (0.15% lysine and 0.05% methionine) on the nutritive value of Candle RSM were also studied. The results of experiment 1 indicated that daily feed intake and carcass value index were not significantly (P > 0.05) affected by diets. The growth and feed utilization responses of pigs fed diets which contained soybean meal and fababeans as the sole source of supplementary protein were similar and the replacement of these protein supplements with Candle RSM, unless supplemented with amino acids, resulted in a reduction in rate of growth and efficiency of feed utilization. Gains adjusted by regression for feed intake variations showed benefit from lysine. Diets containing 15 % of either Candle or Tower RSM, plus lysine, were utilized about 95% as efficiently as soybean meal diets. Supplementation with iodine produced no significant response. The digestibility coefficients of the protein and energy of Candle RSM and soybean meal were determined in experiment 2. The apparent digestibility of protein in Candle RSM was 81% and energy digestibility was 71%. The digestible energy content was 14.12 MJ/kg (3370 kcal/kg), dry matter basis.

Initial Weight

First- and second-litter progeny from sows fed either 0 or 8% solvent-extracted rapeseed meal in replacement for isonitrogenous amounts of soybean meal and wheat was used to evaluate solvent-extracted rapeseed meal as a protein source. There was no influence of the dam’s diet on gain, efficiency of feed utilization, digestible (DE) and metabolizable energy (ME) or digestible nitrogen (DN) and nitrogen retention in the progeny. In pigs from first litters, the feeding of 8% rapeseed meal, compared with 0% rapeseed meal, depressed feed intake and rate of gain in the finishing period from 55 to 90 kg liveweight, and resulted in reduced gain and poorer efficiency of feed utilization for the overall experiment from 6 kg initial weight. Carcasses from rapeseed meal-fed pigs were leaner. Gilt carcasses were leaner than barrow carcasses. With second-litter pigs, there were no significant differences associated with dietary treatment or sex. There were no significant differences in DE or ME or in DN and nitrogen retention between pigs receiving 0 or 8% rapeseed meal in either the starting diets at 6 weeks of age or the growing diets at 40 kg liveweight.

Colon And Rectum

The usefulness of amino acid digestibility measurements as indices of availability can be evaluated by comparing the amino acid composition of distal ileal digesta (where absorption is believed to be complete) with that in the rectum. Two semipurified diets containing either soybean or rapeseed oil meals were each fed to four castrated male pigs of 60 kg liveweight. The pigs were sacrified and samples of digesta were removed from the stomach, duodenum, jejunum, ileum, cecum, colon, and rectum. The concentrations of nitrogen and the proportions of 14 amino acids in the samples were studied. Digesta taken from the duodenum contained the greatest concentration of nitrogen; the nitrogen concentration decreased through the small intestine, and then remained constant through the large intestine. Comparing the ileal and rectal digesta, there were no significant differences in the proportions of valine, arginine, serine, tyrosine, threonine, phenylalanine, and aspartic acid for both diets. This was also true for lysine for the soybean meal diet and for methionine and alanine for the rapeseed meal diet, so that for these amino acids, digestibility should be a good estimate of availability. However, there were lower proportions of leucine plus glycine, proline, and glutamic acid in the rectal than in the ileal contents for both diets, and for lysine in the rapeseed meal diet, suggesting that digestibility values would overestimate availability. In contrast, there were higher proportions of isoleu-cine in the rectal than in the ileal contents for both diets, and of methionine and alanine for the soybean meal diet, suggesting that digestibilities would underestimate the availabilities of these amino acids.Partition of the digesta and the water-soluble digestion marker (polyethylene glycol) in the stomach precluded reliable quantitation of digesta flows through the ileum, but the experiment suggests that such quantitative measures would provide a basis for more valid estimates of amino acid availabilities than measurements of the amounts of amino acids voided in the feces.

The Difference

Abstract Indigestible fiber–protein–phytate complexes reduce the feeding value of soy products. We investigated the effects of multienzyme supplement (MES, Victus) on standardized ileal digestibility (SID) of amino acids (AA) and apparent total tract digestibility (ATTD) of energy and minerals in roasted full-fat soybean (FFSB) seeds and expelled-extruded soybean meal (SBM) fed to growing pigs. The crude protein (CP) was 33.4% and 42.8% dry matter (DM) in FFSB seeds and SBM, respectively and corresponding values for crude fat were 17.4% and 11.8% DM. Semi-purified diets with 50% of either FFSB seeds or SBM as the sole source of AA were prepared without or with MES supplying phytase, protease, xylanase, and β-glucanase at 2,200, 8,300, 400, and 100 U/kg of feed, respectively. Diets had TiO2 as an indigestible marker and the ratio of cornstarch to sucrose and corn oil was identical to calculate DE by the difference method. Eight ileal-cannulated barrows (22.1 ± 0.61 kg) were fed diets in a replicated 4 × 4 Latin square design to give eight replicates per diet. The period lasted for 9 d: 5 d for acclimation, 2 d for fecal, and 2 d for ileal digesta samples. There was no (P > 0.05) interaction between soy type and MES or MES effect on SID of AA; SBM had higher (P < 0.05) SID of CP, His, Leu, and Lys. There was no (P > 0.05) interaction between soy type and MES on energy digestibility. The FFSB seeds had higher ATTD of gross energy (GE, 80.2% vs. 76.6%; P < 0.01) than SBM. Pigs fed MES had higher (P < 0.05) ATTD of DM (91.3% vs. 87.7 %), GE (87.5% vs. 82.4%), CP (86.4% vs. 82.9%), crude fat (70.6% vs. 54.9%), Ca (63.2% vs. 60.2%), and P (67.5% vs. 63.2%). In conclusions, differences on AA and energy digestibility in soy products could be linked to processing and compositional differences. Although MES had no effect on SID of AA, the effects on the utilization of minerals and energy demonstrated the value of fiber-degrading enzymes, protease, and phytase in improving the nutritive value of soy products independent of processing.

Protein Sources

Semi-purified diets containing either soybean or rapeseed meal were fed to four barrow pigs of 60-kg liveweight in balance study cages. Comparison of feed intake and feces and urine output showed that the apparent digestibilities and biological values of the soybean meal-containing diet were 87.8 and 84.0%, respectively; the corresponding values for the rapeseed meal-containing diet were 78.4 and 78.9%. Samples of feed and feces were hydrolyzed and the n-propyl N-acetyl esters of the amino acids were prepared and separated by gas-liquid chromatography. Apparent digestibilities of the amino acids in the two protein sources were calculated; for soybean meal the values ranged between 85 and 92%, with the exception of methionine, for which the value was only 79%; the value for lysine was 90%. The corresponding values for rapeseed meal were 74 and 86%, with values of 87% for both methionine and lysine. An attempt to use polyethylene glycol as a digestion indicator failed, because rapeseed meal appeared to contain material which interfered with the development of turbidity; however, for the soybean meal-containing diet there were no significant differences between the apparent digestibility values determined with the indicator and those determined using total feces collection.

Two growth trials involving a total of 36 individually fed Yorkshire gilts were conducted to compare the value of supplemental protein from soybean meal, raw soybeans, and cooked soybeans for growing pigs. Three metabolism trials were also conducted. Cooked soybeans were prepared by cooking in water for approximately 6 hr. The protein supplements were fed at a level calculated to supply the same amount of supplemental protein daily. Performance of pigs fed soybean meal or cooked soybeans was similar and superior to that of pigs fed raw soybeans as indicated by rate of gain, feed intake, and gain to feed ratio. The higher gross energy of cooked soybeans or raw soybeans did not result in increased digestible or metabolizable energy content of the diet. Protein digestibility and retention was lower for diets containing raw soybeans.

Matter Basis

Twenty gilts and 20 barrows were fed 0, 5 or 10% ground rapeseed in diets with or without rapeseed meal (RM) and either adjusted or unadjusted for levels of digestible energy (DE) and total protein. Dietary rapeseed at a level of 10% depressed (P < 0.10) feed intake and improved (P < 0.01) feed conversion in comparison with 0% rapeseed, but did not significantly influence efficiency of DE conversion. Pigs fed rapeseed gained 0.05 to 0.11 kg/day more slowly than those fed no rapeseed, but differences were not significant. Carcass dressing percentage was lower (P < 0.05) for pigs fed 5 or 10% rapeseed in diets without RM than it was for those fed a diet with 0% rapeseed or with 5% rapeseed plus 4% RM. The former pigs also had carcass measurements that suggested leaner carcasses. Data on rapeseed composition, including amino acid values, are presented. Coefficients for DE, metabolizable energy (ME), ME corrected to N equilibrium (MEn), and digestible N (DN) at 21 kg liveweight were not influenced by diet. The DE, ME, MEn and DN per unit of feed were increased by the addition of 10% rapeseed to the diet. Rapeseed had a calculated DE of 5703 kcal/kg on a dry matter basis. The DE, ME and MEn were highly correlated (r = 0.970 to 0.997), indicating little difference in accuracy between these energy measures. Daily N retained averaged 16.8 g and was not influenced by diet. Barrows ate more, required more feed and more DE/kg gain and had poorer carcasses than gilts. The DE, ME, MEn and DN were significantly higher for barrows than for gilts. The data suggest that when 5 or 10% rape-seed is fed to growing pigs from 8 kg initial weight, a depression of approximately 2% in feed intake can be expected for each 1% of dietary rapeseed added, regardless of whether DE and protein adjustments are made. Improved feed conversion when rapeseed is fed occurs in association with the high gross energy content of the seed.

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.

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.

Four castrated pigs, each fitted with a re-entrant cannula in the terminal ileum, were used to study digestion in the small intestine. A nitrogen-free diet was used for the estimation of metabolic nitrogen and amino acids. Faba beans, as the sole source of dietary protein, were used raw or after autoclaving for 30 or 60 min. The four diets were fed to the pigs in a 4 × 4 latin square experiment. The pigs were fed each diet for 6 days prior to a 24-hr collection of total ileal contents. Autoclaving of faba beans had no significant effect on digestibility of dry matter, gross energy, nitrogen and individual amino acids except arginine, which was significantly increased. The intestinal uptake of arginine was the highest and of cystine the lowest in all faba bean diets. It was concluded that autoclaving faba beans had no beneficial effect on the digestion of nutrients in the small intestine of the pig.

Abstract The objective was to determine the influence of amino acid (AA) supplementation during the adaptation period on the ileal digestibility of crude protein and AA in corn and soybean meal (SBM). Six barrows with an initial body weight of 30.9 ± 2.6 kg fitted with a T-cannula in the distal ileum were assigned to a 6 × 6 Latin square design with 6 dietary treatments and 6 periods. Two experimental diets contained corn or SBM as the sole source of AA and an N-free diet was additionally prepared. For AA supplementation groups, an AA mixture consisted of Gly, Lys, Met, Thr, Trp, Ile, Val, His, and Phe was added to the corn diet and the N-free diet at the expense of cornstarch, and an AA mixture of Lys, Met, and Thr was added to the SBM diet. All diets contained 0.5% of chromic oxide. The 6 experimental diets were fed to the pigs for 4 and half days, and the 3 diets containing AA mixture were switched to the respective diets without AA mixture during the following 2 and half days. Ileal digesta were collected during the last 2 days. The addition of AA mixture during the adaptation period caused increased apparent ileal digestibility of Arg and Trp in corn (P &lt; 0.05), but did not affect that in SBM. The addition of AA mixture during the adaptation period caused increased apparent ileal digestibility of Pro and Gly regardless of feed ingredient (P &lt; 0.05), but did not affect that of other AA. All AA except Pro in corn and SBM were unaffected by the addition of AA mixture during the adaptation period. In conclusion, the addition of amino acid during the adaptation period does not affect the standardized ileal digestibility of indispensable amino acids in feed ingredients.
