Growth Trial

A study was conducted to estimate the net energy (NE) content of canola meal (CM) and full-fat canola seeds (FFCS) in growing pigs, and to validate the results through a growth trial. The digestible energy (DE) content of the canola products was measured in a digestibility study by the difference method, with diets containing two-thirds of a basal diet of known digestibility and one-third of the canola products. The NE content was estimated by means of a prediction equation based on the DE content and chemical composition of the canola products. The NE was 2.43 and 3.56 Mcal kg-1 DM for CM and FFCS, respectively. For the growth study, 31-kg pigs (18 per treatment) were fed for 35 d with wheat/barley-based diets containing either 0, 5, 10 or 15% FFCS or 0, 7.5, 15 or 22.5% CM. The gain-to-feed ratio was unchanged by the levels of CM or FFCS (P > 0.05), but the highest level of FFCS decreased feed intake (P < 0.001) and thus increased the gain-to-feed ratio (P < 0.05). In conclusion, the NE content was correctly estimated for CM, but slightly underestimated for FFCS. Also, growing pigs can tolerate diets containing up to 22.5% CM or 10% FFCS.Key words: Net energy, growing pigs, canola meal, full-fat canola seeds

The study aimed to compare the digestible and net energy (DE and NE) contents of three canola meals (CM) toasted (95°C) or not after desolventization from yellow Brassica junceae (YBJ) and yellow and black Brassica napus (YBN and BBN) in growing pigs. A basal diet and six CM-based diets (2/3 basal diet and 1/3 CM) supplemented with acid-insoluble ash (indigestible marker) were prepared. The growing pigs (28 kg; six per treatment) were kept in metabolic cages for 18 d and their faeces were collected for the last 10 d. The digestibilities and DE content of the CM were determined based on the total faecal excretion and the indigestible marker method. NE was estimated with a prediction equation. The DE and NE contents of the YBN meal (3.98 and 2.73 Mcal kg-1 DM) were higher (P = 0.007) than that of the YBJ (3.76 and 2.59 Mcal kg-1 DM) and BBN (3.64 and 2.43 Mcal kg-1 DM) meals. Toasting had no effect (P > 0.05) on the DE and NE contents. Inconsistent values were obtained with the indigestible marker, as compared with the total faecal collection method. In conclusion, YBN canola presents the highest energy content, and toasting of CM does not affect its energy values in growing pigs.Key words: Canola meal, growing pigs, toasting, digestible energy, net energy

The Difference

Two experiments (Exp.) were conducted to determine the nutritive value of wheat-derived wet concentrated distillers solubles (CDS) for growing pigs. In Exp. 1, standardised ileal digestibility (SID) of amino acids (AA) was determined by the difference method, using six ileally cannulated barrows (initial bodyweight (BW) of 31 ± 2.9 kg). The pigs were fed a casein-corn starch-based diet supplemented with wheat CDS so that about half of the crude protein (CP) originated from either wheat CDS or from casein. In Exp. 2, 12 barrows with an initial BW of 17 ± 0.9 kg were used to determine digestible energy (DE) content, and to calculate metabolisable energy (ME) and net energy (NE) content of wheat CDS. Animals were fed either a casein-corn starch-based basal diet or a CDS diet containing 470 g/kg of the basal diet and 530 g/kg wheat CDS on a dry matter (DM) basis. Values of SID of CP and AA in Exp. 1 amounted to 85, 74, 83 and 70% for CP, lysine, methionine and threonine, respectively. The DE, ME and NE contents of wheat CDS were 16.8, 15.8 and 11.1 MJ/kg DM, respectively. It can be concluded that SID of CP and AA and also the energy content in wheat CDS are substantially higher than corresponding values reported in international tables with information on nutritional value of dried co-products of bioethanol production.

The Impact

Abstract The objective of this project was to determine the impact of feeding growing pigs with high wheat millrun diets supplemented with a multi-carbohydrase enzyme (amylase, cellulase, glucanase, xylanase, and invertase activities) on nutrient digestibility, growth performance, and greenhouse gas (GHG) output (carbon dioxide, CO2; nitrous oxide, N2O; methane, CH4). Three experiments were conducted utilizing six treatments arranged as a 3 × 2 factorial (0%, 15%, or 30% wheat millrun; with or without enzyme) for the digestibility experiment or as a 2 × 2 factorial (0% or 30% wheat millrun; with or without enzyme) for the performance and GHG experiments. The digestibility, performance, and GHG experiments utilized 48 individually housed pigs, 180 pigs housed 5 per pen, or 96 pigs housed 6 per chamber, respectively. Increasing wheat millrun up to 30% in the diet of growing pigs resulted in decreased energy, nitrogen (N) and phosphorus (P) apparent total tract digestibility and net energy content (P &lt; 0.01). Overall, average daily gain (ADG) and gain to feed ratio were reduced in pigs fed wheat millrun (P &lt; 0.05). Enzyme supplementation had minimal effects on the digestibility or performance parameters measured. Feeding diets with 30% millrun did not affect GHG output (CH4: 4.7 and 4.9; N2O: 0.45 and 0.42; CO2: 1,610 and 1,711 mg/s without or with millrun inclusion, respectively; P &gt; 0.78). Enzyme supplementation had no effect on GHG emissions (CH4: 4.5 and 5.1; N2O: 0.46 and 0.42; CO2: 1,808 and 1,513 mg/s without or with enzymes, respectively; P &gt; 0.51). Overall, the carbohydrase enzyme had minimal effects on parameters measured, regardless of wheat millrun inclusion (P &gt; 0.10). Although energy, N and P digestibility, and ADG were reduced, the inclusion of up to 30% wheat millrun in the diet has no effect on GHG emissions from growing pigs (P &gt; 0.10).

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.

The Difference

Abstract Carinata meal is increasingly available for livestock feeding. However, the effects of supplemental phytase and fiber degrading enzymes on nutritive value of carinata meal for pigs have not been reported. Objective of the study was to evaluate the standardized ileal digestibility (SID) of amino acid (AA), and digestible energy (DE) and net energy (NE) values of phytase- and fiber-degrading enzymes-supplemented carinata meal for growing pigs. Ten ileal-cannulated pigs (initial body weight = 53.9 ± 4.76 kg) were fed 4 diets in a replicated 4 × 4 Latin square design with two additional columns to give 10 replicates per diet. Diets included a corn-soybean meal (SBM)-based basal diet, basal diet with 25% carinata meal, basal diet with 25% carinata meal plus phytase at 2,000 FTU/kg and multi-carbohydrase at 0.2 g/kg, and in addition a nitrogen-free diet. The multicarbohydrase supplied 4 units of xylanase, 10 units of β-glucanase, and 1,000 units of pectinase per kilogram of diet. The ratio of corn to SBM and soybean oil in carinata meal-containing diets was identical to that in the corn-SBM-based basal diet to allow calculation of AA and energy digestibility of carinata meal by the difference method. On a dry matter basis, carinata meal contained 50.2% crude protein, 0.88% ether extract, 15.37% acid detergent fiber, 1.82% Lys, 0.96% Met, 1.89% Thr, and 0.64% Trp, respectively. The SID of Lys, Met, Thr, and Trp for carinata meal were 51.4%, 82.2%, 65.9%, and 85.9%, respectively. The DE and NE values for carinata meal were 3,427 and 1,828 kcal/kg of dry matter, respectively. Supplementation of a combination of phytase and multicarbohydrase did not affect the apparent ileal digestibility of AA and SID of AA for the corn-SBM-carinata meal-based diet, and for the carinata meal. However, the combination of phytase and multicarbohydrase did improve (P &lt; 0.05) apparent total tract digestibility, and DE and NE values for carinata meal by 9.4%, 9.5%, and 12.4%, respectively. In conclusion, the enzymes used in the current study could be added in carinata meal-based diets for growing pigs to improve the energy value.

Abstract Objective of the study was to determine the effect of supplementing a combination of phytase and multi-carbohydrase on standardized ileal digestibility (SID) of amino acid (AA) and net energy (NE) value of carinata meal for growing pigs. Ten ileal-cannulated barrows (initial body weight = 53.9 ± 4.76 kg) were fed 4 diets in a replicated 4 × 4 Latin square design with 2 additional columns to give 10 replicates per diet. Diets included a corn-soybean meal (SBM)-based basal diet, the basal diet with 25% carinata meal, basal diet with 25% carinata meal plus phytase at 2,000 FTU/kg and multi-carbohydrase at 0.2g/kg, and a nitrogen-free diet. The multi-carbohydrase supplied 4 units of xylanase, 10 units of β-glucanase, and 1000 units of pectinase per kilogram of diet. The ratio of corn to soybean meal and soybean oil in carinata meal- containing diets was identical to that in the corn-soybean meal based basal diet to allow calculation of AA and energy digestibility of carinata meal by the difference method. On a DM basis, carinata meal contained 50.2% CP, 0.88% ether extract, 15.37% ADF, 1.82% Lys, 0.96% Met, 1.89% Thr, and 0.64% Trp, respectively. The SID of Lys, Met, Thr, and Trp for carinata meal were 51.4%, 82.2%, 65.9%, and 85.9%, respectively. Supplementation of a combination of phytase and multi-carbohydrase did not affect the SID of AA for the corn-SBM-carinata meal-based diet, and for the carinata meal. However, supplementation of a combination of phytase and multi-carbohydrase improved (P = 0.015) the apparent total tract digestibility of gross energy, and DE and NE values for carinata meal by 9.4, 9.5, and 12.4% respectively. In conclusion, the enzymes used in the current study could be added in carinata meal-based diets for pigs to improve the energy value of the carinata meal.

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.

A digestibility and balance trial was carried out with four intact castrated male pigs (live weight 33-82 kg) to study the effects of dietary crude protein and energy content on nutrient digestibility, nitrogen metabolism, water intake and urinary output. In a 4 x 4 Latin square design, four barley-oats-soya bean meal based diets were arranged 2x2 factorially. The corresponding factors were dietary crude protein (CP) content: high (180 g/kg CP) or low protein diet (140 g/kg CP) supplemented with free lysine, methionine and threonine; and dietary net energy content; high (1.05 feed units (FU)/kg) (feed unit=9.3 MJ net energy) or low net energy content (0.95 FU/kg). Lowering dietary CP content (mean values of 189 to 152 g/kg dry matter, respectively) by supplementation of free amino acids decreased urinary nitrogen (N) excretion by 6.9 g/day (32%) (P
