Abstract This study was designed to determine the effect of dietary supplementation of xylanase on growth performance, nutrient digestibility, organ weight, digesta pH, and concentration of short-chain fatty acids (SCFA) of weaned pigs fed wheat–canola meal (CM) diets over a 35-d period. A total of 144 piglets (72 barrows and 72 gilts) weaned at 18 ± 2 d of age, with initial body weight (BW) of 6.2 ± 0.7 kg, received one of eight dietary treatments based on randomized complete block design. BW and feed intake were recorded weekly to calculate average daily gain (ADG), average daily feed intake (ADFI), and feed efficiency (G:F). Treatments consisted of a control wheat–soybean meal-based diet and wheat-regular (RCM), dehulled (DCM), or coarse CM (CCM) without and with 16,000 BXU/kg xylanase (Econase XT). All diets contained 500 FTU/kg of phytase (Quantum Blue 5G) and titanium dioxide (0.3%). Apparent total tract digestibility (ATTD) of neutral detergent fiber (NDF), crude protein (CP), phosphorous (P), calcium (Ca), dry matter, and diet were determined. On day 35, one pig per pen was euthanized to evaluate the main factors of protein, xylanase supplementation, and sex on organ weight, ileal and colon digesta pH, and colon digesta concentrations of SCFA. The main factors did not affect growth performance. Xylanase supplementation improved nutrient digestibilities in all diets and increased ileal and colonic digesta pH without affecting the growth performance of weaned pigs fed wheat and CM-based diets. A protein–xylanase effect (P < 0.05) resulted in increasing the ATTD of NDF from 28% to 32% and from 29% to 37% for RCM and DCM, respectively. The ATTD of CP was greater (P < 0.05) with xylanase supplementation (75% vs. 70%). Xylanase supplementation increased ATTD of P and Ca. A three-way interaction (P < 0.05) for protein–xylanase–gender for colon pH, acetic, and propionic acid in the colon digesta of pigs indicated that, in addition to the protein source, piglet sex could have influenced how xylanase works. Xylanase supplementation increased (P < 0.05) the weight of the liver and spleen and tended (P < 0.10) to increase the size of the kidney. In conclusion, dietary supplementation of xylanase increased nutrient digestibility and digesta pH but did not influence the growth performance of weaned pigs fed wheat and CM-based diets over a 35-d period.

Abstract Canola meal (CM) is widely included in swine diets, but its fiber matrix compromises its nutritional value. Whether steam-explosion with high pressure can increase nutrient digestibility of CM and hence growth performance in pigs is unknown. To explore, Brassica napus CM was processed with steam pressure at 700 or 1,100 kPa for 5 min followed by a sudden release of pressure to produce steam-exploded CM7 and CM11, respectively. Four diets containing 20% CM, CM7, CM11, or soybean meal (SBM) were formulated to provide 2.3 Mcal net energy (NE)/kg and 5.1 g standardized ileal digestible lysine/Mcal NE. From 2 weeks post-weaning, 256 pigs (BW, 10 kg) were fed the 4 diets for 4 weeks in a randomized complete block design with 16 blocks and 4 pigs per pen. Apparent total tract digestibility (ATTD) of dry matter (DM), crude protein (CP), and gross energy (GE) was 4.8, 4.3 and 3.7%-units lower (P < 0.05), respectively, for the 3 CM diets than the SBM diet, whereas diet digestible energy (DE) value was not different. Steam-explosion of CM did not affect diet ATTD of DM and GE, but reduced (P < 0.05) diet ATTD of CP. For the entire trial (day 1–28), steam-explosion at either 700 or 1,100 kPa increased (P < 0.05) average daily feed intake (ADFI) of CM, but the CM diet had lower (P < 0.05) ADFI than the SBM diet. Average daily gain (ADG) did not differ among the 4 diets. Consequently, feed efficiency (G:F) was greater (P < 0.05) for the 3 CM diets than the SBM diet. In conclusion, steam-explosion of CM did not increase diet nutrient digestibility or growth performance of weaned pigs.

Abstract Canola meal (CM) contains less crude protein (CP) and more fiber and anti-nutritional factors (ANF) such as glucosinolates than soybean meal (SBM), and consequently has a lower nutrient digestibility. Therefore, processing strategies that may increase the feeding value of CM, warrant study. In 2 experiments, the effects of extrusion of Brassica napus CM on apparent (AID) and standardized ileal digestibility (SID) of amino acids (AA), apparent total tract digestibility (ATTD) of gross energy (GE) in growing pigs and growth performance and diet digestibility in weaned pigs were assessed. Solvent-extracted CM was extruded using a single-screw extruder at 3 screw speeds, 250 (CM-250), 350 (CM-350) or 450 (CM-450) rpm. In Exp. 1, in a double 4 × 4 Latin square, 8 ileal-cannulated barrows (initial BW, 68.1 kg) were fed corn starch-based diets containing 50% CM or extruded CM. The CM sample contained 43.2% CP, 33.2% total dietary fiber, and 8.9 µmol total glucosinolates/g on dry matter (DM) basis. Extrusion increased (P &lt; 0.05) the AID of CP, reduced (P &lt; 0.05) hindgut fermentation (AHF) of CP, and decreased (P &lt; 0.05) predicted net energy (NE) value of diets. Extrusion increased diet AID and CM SID of most indispensable AA by 3.1 to 5.3%-units. In Exp. 2, 200 weaned pigs (initial BW, 8.3 kg) were fed diets containing 20% SBM, CM, or extruded CM starting 2 wk post-weaning for 3 wk. The CM sample contained 42.7% CP, 28.3% total dietary fiber, and 5.3 µmol total glucosinolates/g DM. Wheat-based diets provided 2.3 Mcal NE/kg and 5.1 g SID Lys/Mcal NE. Dietary inclusion of extruded CM replacing SBM decreased (P &lt; 0.05) diet ATTD of DM, GE and CP, and DE value. Average daily feed intake (ADFI), average daily gain (ADG), and gain:feed (G:F) of pigs did not differ between extruded CM and SBM diets and were not affected by extrusion, but increasing extruder screw speed linearly increased (P &lt; 0.05) ADG for d 1 to 7, and G:F for the entire trial. In conclusion, extrusion increased diet AID and CM SID of AA, but not DE and predicted NE values of CM. However, increasing extruder speed did not further increase SID of most AA of CM in growing pigs. Dietary inclusion of 20% CM or extruded CM did not affect growth performance in weaned pigs.

Abstract This study was to determine the effect of dietary supplementation of xylanase on growth performance, nutrient digestibility, organ weight, digesta pH and concentration of short-chain fatty acids (SCFA) of weaned pigs fed wheat-canola meal-based diets over a 35-d period. A total of 144 piglets (6.2 ± 0.7 kg) received one of 8 diets based on a randomized complete block design. Body weight and feed intake were recorded weekly to calculate average daily gain (ADG), average daily feed intake (ADFI), and feed efficiency(G:F). Treatments consisted of a control wheat-SBM-based diet and wheat-regular (RCM), dehulled (DCM) or coarse (CCM) canola meal. All diets contained 500 phytase units (FTUs/kg; Quantum Blue-5G), and titanium-dioxide (0.3%), and were fed without and with 16,000 Birch-Xylan Units of xylanase (BXU/kg; Econase-XT). Apparent total tract digestibilities (ATTD) of NDF, CP, P, Ca, DM, and diet were determined. On d 35, one pig per pen was euthanized to evaluate the effect of treatment on organ weight, digesta pH, and digesta concentration of SCFA. Treatment did not affect growth performance. Xylanase supplementation improved nutrient digestibilities, without affecting growth performance. The ATTD of NDF was greater (P &lt; 0.05; 48%) in the wheat-SBM+xylanase, wheat-SBM without xylanase (46%), and DCM+xylanase (45%) diets. The ATTD of CP was greater (P &lt; 0.05; 78%) in wheat-SBM+xylanase, and wheat-DCM+xylanase (75%), diets. Xylanase supplementation increased ATTD of P and Ca by 9 and 19%; whereas ileum and colon digesta pH increased by 6 and 3%. Supplementing xylanase to DCM increased butyric acid by 10%, whereas the concentration of acetic acid increased by 24% in colon-digesta of pigs fed CCM+xylanase. In conclusion, dietary supplementation of xylanase increased nutrient digestibilities, digesta pH without affecting growth performance of weaned pigs fed wheat and canola meal-based diets. Additionally, supplemental xylanase increased butyric acid concentration in colon digesta of pigs fed wheat-DCM diets.

Digesta Viscosity

Fibrous components in canola meal and wheat limit their effective use in diets for weaned pigs. Effects of supplementing a carbohydrase (845 and 327 Units g-1 xylanase and β-glucanase) to a wheat-canola meal diet on growth performance, small intestine nutrient digestibility and digesta viscosity were investigated. Ninety-six weaned pigs (7.2 ± 1.2 kg) had free access to control diet [65% wheat, 25% canola meal; 3.15 Mcal digestible energy (DE) kg-1, 10.6 g digestible lysine kg-1] or control diet supplemented with carbohydrase at three inclusion rates (1, 2, or 4 g kg-1) for 28 d. Four pigs were housed per pen for six pens per diet. On days 19 to 21, six pigs per diet were euthanised to collect small intestine digesta. Carbohydrase increased average daily feed intake (ADFI) and average daily gain (ADG) quadratically (P < 0.01) for days 1 to 28, resulting in 16% higher ADFI and 13% higher ADG for 2 g kg-1 carbohydrase compared to control. Carbohydrase did not affect feed efficiency (P > 0.10). The ADG was positively correlated to ADFI (r = 0.94; P < 0.01), but not to feed efficiency (P > 0.10). Carbohydrase did not affect digestibility of dry matter (DM) and energy (P > 0.10). Carbohydrase at 4 g kg-1 only reduced digesta viscosity 30% in the distal small intestine compared to control (P < 0.05). Carbohydrase supplementation increased ADFI and thereby ADG, but not feed efficiency and nutrient digestibility, suggesting that reduction of dietary fibrous components using carbohydrase may stimulate voluntary feed intake of pigs fed diets limiting in DE.

The effects of substituting wheat with crude glycerol as a dietary energy source were evaluated. Seventy-two weaned pigs were fed for 4 wk one of three pelleted wheat-based diets containing 0, 4, or 8% glycerol and formulated to 2.28 Mcal kg-1 net energy (NE) and 5.02 g standardized ileal digestible lysine Mcal-1 NE. For day 0 to 28, body weight increased linearly (P = 0.04); pigs fed 8% glycerol were 1.11 kg heavier than pigs fed 0% glycerol. Glycerol inclusion tended to increase average daily gain linearly (P = 0.066) and increased average daily feed intake quadratically (P = 0.037) without affecting feed efficiency (P > 0.10). Feeding up to 8% dietary crude glycerol by substituting wheat can enhance the growth performance of weaned pigs. Key words: Co-product, digestibility, glycerol, weaned pig
