Supplemental Protein

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.

Objective: The objective of this study was to determine net energy (NE) of expeller-press (EP-RSM) and solvent-extracted rapeseed meal (SE-RSM) and to establish equations for predicting the NE in rapeseed meal (RSM) fed to growing pigs.Methods: Thirty-six barrows (initial body weight [BW], 41.1±2.2 kg) were allotted into 6 diets comprising a corn-soybean meal basal diet and 5 diets containing 19.50% RSM added at the expense of corn and soybean meal. The experiment had 6 periods and 6 replicate pigs per diet. During each period, the pigs were individually housed in metabolism crates for 16 days which included 7 days for adaption to diets. On day 8, pigs were transferred to respiration chambers and fed their respective diet at 2,000 kJ metabolizable energy (ME)/kg BW<sup>0.6</sup>/d. Feces and urine were collected, and daily heat production was measured from day 9 to 13. On days 14 and 15, the pigs were fed at 890 kJ ME/kg BW<sup>0.6</sup>/d and fasted on day 16 for evaluation of fasting heat production (FHP).Results: The FHP of pigs averaged 790 kJ/kg BW<sup>0.6</sup>/d and was not affected by the diet composition. The NE values were 10.80 and 8.45 MJ/kg DM for EP-RSM and SE-RSM, respectively. The NE value was positively correlated with gross energy (GE), digestible energy (DE), ME, and ether extract (EE). The best fit equation for NE of RSM was NE (MJ/kg DM) = 1.14×DE (MJ/kg DM)+0.46×crude protein (% of DM)–25.24 (n = 8, R<sup>2</sup> = 0.96, p<0.01). The equation NE (MJ/kg DM) = 0.22×EE (% of DM)–0.79×ash (% of DM)+14.36 (n = 8, R<sup>2</sup> = 0.77, p = 0.018) may be utilized to quickly determine the NE in RSM when DE or ME values are unavailable.Conclusion: The NE values of EP-RSM and SE-RSM were 10.80 and 8.45 MJ/kg DM. The NE value of RSM can be well predicted based on energy content (GE, DE, and ME) and proximate analysis.

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 An experiment was performed to evaluate the energy content of extruded-expelled soybean meal (EESBM) and the effects of heat treatment on energy utilization in growing pigs. Eighteen growing barrows (18.03 ± 0.61 kg initial body weight) were individually housed in metabolism crates and randomly allotted to one of three dietary treatments (six replicates/treatment). The three experimental diets were: a corn-soybean meal-based basal diet and two test diets with simple substitution of a basal diet with intact EESBM or heat-treated EESBM (heat-EESBM) at a 7:3 ratio. Intact EESBM was autoclaved at 121°C for 60 min to make heat-treated EESBM. Pigs were fed the experimental diets for 16 d, including 10 d for adaptation and 6 d for total collection of feces and urine. Pigs were then moved into indirect calorimetry chambers to determine 24-h heat production and 12-h fasting heat production. The energy content of EESBM was calculated using the difference method. Data were analyzed using the Mixed procedure of SAS with the individual pig as the experimental unit. Pigs fed heat-EESBM diets showed lower (P &lt; 0.05) apparent total tract digestibility of dry matter (DM), gross energy, and nitrogen than those fed intact EESBM. A trend (P ≤ 0.10) was observed for greater heat increments in pigs fed intact EESBM than those fed heat-EESBM. This resulted in intact EESBM having greater (P &lt; 0.05) digestible energy (DE) and metabolizable energy (ME) contents than heat-EESBM. However, no difference was observed in net energy (NE) contents between intact EESBM and heat-EESBM, showing a tendency (P ≤ 0.10) toward an increase in NE/ME efficiency in heat-EESBM, but comparable NE contents between intact and heat-EESBM. In conclusion, respective values of DE, ME, and NE are 4,591 kcal/kg, 4,099 kcal/kg, and 3,189 kcal/kg in intact EESBM on a DM basis. It is recommended to use NE values of feedstuffs that are exposed to heat for accurate diet formulation.

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.

Objective: The objective of this study was to determine the digestible energy (DE) and metabolizable energy (ME) of yellow dent corn sourced from different meteorological origins fed to growing pigs and develop equations to predict the DE and ME of yellow dent corn from southwestern China.Methods: Sixty crossbred barrows were allotted to 20 treatments in a triplicate 20×2 incomplete Latin square design with 3 replicated pigs per dietary treatment during 2 consecutive periods. Each period lasted for 12 days, and total feces and urine during the last 5 days of each period were collected to calculate the energy contents.Results: On dry matter (DM) basis, the DE and ME in 20 corn grain samples ranged from 15.38 to 16.78 MJ/kg and from 14.93 to 16.16 MJ/kg, respectively. Selected best-fit prediction equations for DE and ME (MJ/kg DM basis) for yellow dent corn (n = 16) sourced from southwestern China were as follows: DE = 28.58–(0.12×% hemicellulose)+(0.35×% ether extract)–(0.83×MJ/kg gross energy)+(0.20×% crude protein)+(0.49×% ash); ME = 30.42– (0.11×% hemicellulose)+(0.31×% ether extract)–(0.81×MJ/kg gross energy).Conclusion: Our results indicated that the chemical compositions, but not the meteorological conditions or physical characteristics could explain the variation of energy contents in yellow dent corn sourced from southwestern China fed to growing pigs.

Twelve samples of rapeseed meal (RM) and one sample of soybean meal (50% protein) (SM) were evaluated for digestible energy (DE), metabolizable energy (ME), nitrogen-corrected ME (MEn) and digestible nitrogen (DN). RM samples were of Brassica campestris and B. napus origin and contained meals processed by solvent, prepress-solvent or expeller processes. Two of the meals were from rapeseeds not in commercial production, one a Bronowski (low glucosinolate) napus meal and one a meal from zero-erucic acid rapeseed of napus type. Energy studies were conducted with 64 pigs at 16, 33 and 65 kg liveweight, adding 25% by weight of the test ingredient to the total diet. The overall means and standard errors for all weight groups for gross energy (GE), DE, ME and MEn, in kcal/g of dry matter, for 10 RM (excluding Bronowski and zero-erucic acid RM) were 4.74 ± 0.12, 3.21 ± 0.18, 2.89 ± 0.19 and 2.64 ± 0.19, respectively, while the values obtained for SM were 4.81 ± 0.08, 4.21 ± 0.16, 3.92 ± 0.17 and 3.64 ± 0.16. There were no significant differences in DE, ME or MEn among the 12 RM samples, or between weight periods. The values for the basal diet were uniform throughout. The overall mean coefficient for DN was 75.9% for RM and 89.2% for SM. The DE, ME and MEn values for RM should be considered as being species specific.

Crossbred Pigs

Thirty-six crossbred pigs, equally divided between gilts and barrows, were fed from an average of 6 wk of age to market weight on three dietary treatments. Isonitrogenous, isocaloric diets were supplemented with either soybean meal (SBM), low glucosinolate rapeseed meal (RSM) from Brassica napus cv. Bronowski or commercial RSM of B. campestris origin. Metabolic studies were conducted at average weights of 14 and 31 kg and there were no significant differences in coefficients for digestible energy, metabolizable energy, digestible nitrogen or nitrogen retention between treatments, between sexes, or between periods. During the first 6 wk of the experiment and for the overall experiment, there was a difference between sexes in their response to low glucosinolate RSM. Barrows gained at a similar rate when fed diets supplemented with either SBM or low glucosinolate RSM, but more slowly on diets supplemented with commercial RSM. Gilts gained more slowly when fed either RSM than when fed a SBM-supplemented diet. The results suggest that there may be a factor, other than glucosinolates, present in RSM that tends to depress performance of gilts but not of barrows. This depression arising from either source of RSM was not associated with digestibility of energy or nitrogen or with nitrogen retention.

ABSTRACTMicronization followed by grinding of brown-seeded sorghum increased starch availability in vitro but had no effect on proximate composition of the grain. In diets containing 70% of sorghum in ground or micronized and ground form, apparent digestibility of dry matter and nitrogen and nitrogen retention by growing pigs were improved (2·5, 5·0 and 12·2% respectively). Addition to the diet of 0*2 g polyethylene glycol per g crude protein in the sorghum fraction produced similar effects. In the ground cereal diet inclusion of polyethylene glycol increased apparent digestibility of gross energy (3·8%) and improved metabolizable energy content by 5·5%, but i n the micronized and ground cereal diet the additive had no effect.

Two lines of chickpea meal (CPI 56296-b of low fibre content, and CPI 61277 of high fibre content) and one pigeonpea meal (UQ 50) were evaluated, relative to soybean meal, as energy and protein sources for growing pigs and rats. The digestible and metabolizable energy contents of the three protein sources were (MJ kg-1, air-dry basis): chickpea CPI 56296-b, 16.2 and 15.3; chickpea CPI 61277, 14.9 and 14.3; and pigeonpea meal, 15.1 and 14.2, respectively. Both lines of chickpea produced a similar growth performance to soybean meal for growing pigs. Feeding pigeonpea meal resulted in a lower dressing percentage (P < 0.05), and growth rate and feed conversion ratio were inferior on a carcass basis (P < 0.01) relative to the other three diets. There were no differences in backfat thickness or lean content in the ham between the groups of pigs fed on the four diets. With rats, both lines of chickpea produced lower dressing percentages and carcass gains relative to soybean meal (P < 0.05). Pigeonpea was inferior, on a carcass basis, to both soybean and chickpea meals. We conclude that both chickpea meals were suitable as energy and protein sources for pigs, and that short-term rat assays predicted the pig response for pigeonpea but not for chickpea meal.

Abstract An experiment was conducted to test the hypothesis that inclusion of an enzyme premix (xylanase and cellulase) in diets based on corn or sorghum and fed to growing pigs improves the apparent total tract digestibility (ATTD) of energy and total dietary fiber (TDF) and concentration of digestible energy (DE) and metabolizable energy (ME). Two basal diets based on corn and soybean meal or sorghum and soybean meal were formulated. Four additional diets were formulated by adding 40% distillers dried grains with solubles (DDGS) or 40% wheat middlings to each of the 2 basal diets. Each of these 6 diets were formulated either without or with an enzyme premix that contained xylanase and cellulase. A total of 144 pigs (61.7 ± 5.3 kg) were allotted to a randomized complete block design with 12 diets and 12 replicate pigs per diet. Pigs were housed individually and adapted to the diets for 12-d, then moved to metabolism crates and after 4 d, urine and feces were collected for 5 d. Data were analyzed as 2 × 2 × 3 factorial with 2 types of diets, two enzymes treatments, and three by-product inclusions. The pig was the experimental unit. The ATTD of gross energy (GE), and DE and ME improved (P &lt; 0.01) if enzymes were added to the diets regardless of the grain source or by-product inclusion (Table 1). No effect of enzymes on ATTD of TDF was observed, ATTD of TDF was greater if DDGS rather than wheat middlings was added to the corn diet (grain source × by-product interaction, P &lt; 0.05). In conclusion, addition of enzymes may have the potential to improve the ATTD of GE, and DE and ME in mixed diets based on corn or sorghum and both without and with inclusion of DDGS or wheat middlings. 3Enz = enzyme premix supplied by ADM Animal Nutrition, Quincy, IL, USA.
