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 < 0.05) the AID of CP, reduced (P < 0.05) hindgut fermentation (AHF) of CP, and decreased (P < 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 < 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 < 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 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.

Standardized Ileal Digestible Lysine

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

Quillaja Saponin

The purpose of this study was to evaluate the effects of dietary supplementation of Quillaja saponin (QS) on growth performance, nutrient digestibility, fecal microbiota, and fecal gas emission in growing pigs. A total of 50 crossbred growing pigs [(Yorkshire × Landrace) × Duroc] with an initial body weight of 23.83 ± 1.95 kg were randomly assigned to 1 of 2 treatments for a 56-day trial with 5 replicate pens per treatment and 5 pigs (2 barrows and 3 gilts) per pen. Dietary treatments including control diet and control diet supplemented with 200 mg/kg QS. The average daily gain was significantly increased during days 0-56, while the fecal ammonia emission on day 56 and fecal coliform bacteria counts on day 28 were significantly decreased in pigs fed with QS containing diet. However, dietary supplementation of QS had no significant effects on apparent total tract digestibility. In conclusion, dietary supplementation of 200 mg/kg QS had beneficial effects on growth performance, fecal microbiota, and fecal gas emission in growing pigs. Considering the carry-over effects, the adaption period should be at least 28 days when supplementing 200 mg/kg QS to the diet of growing pigs for improving the growth performance.

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).

This study was conducted to evaluate the effect of supplementation of different flavors (apple and anise) on growth performance, nutrient digestibility, blood profiles, and carcass quality in growing–finishing pigs. A total of 96 growing pigs [(Yorkshire × Landrace) × Duroc] with an average body weight (BW) of 28.2 ± 0.7 kg were randomly assigned to one of the following three treatments: (1) CON, basal diet; (2) APF, basal diet + 0.05% apple flavor; (3) ANF, basal diet + 0.05% anise flavor, according to their BW and sex in this 15 wk experiment. There were eight replications (pens) per treatment and four pigs per pen (two barrows and two gilts). During week 0–5, pigs fed ANF diets had greater (p < 0.05) average daily gain (ADG) and average daily feed intake than those fed CON and APF diets. Dietary ANF treatment increased (p < 0.05) ADG during 0–15 wk compared with CON treatment. At the end of 5 wk, the apparent total tract digestibility of nitrogen in ANF treatment was improved (p < 0.05) compared with that in CON treatment. Dietary treatments did not affect the studied traits of carcass and meat quality. The inclusion of anise flavor increased ADG, but apple flavor had no effect on growth performance in growing–finishing pigs.

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 &lt; 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 &lt; 0.05) with xylanase supplementation (75% vs. 70%). Xylanase supplementation increased ATTD of P and Ca. A three-way interaction (P &lt; 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 &lt; 0.05) the weight of the liver and spleen and tended (P &lt; 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 This experiment evaluated varying levels of Amarula (Sclerocarya birrea A. Rich) nut cake (ANC) on growth performance, nutrient digestibility and carcass characteristics in pigs. Thirty Large White × Landrace (LW × LR) pigs were stratified by weight (average live weight of 20 ± 5 kg) and randomly allocated to the five experimental diets that contained 0 (control), 50, 100, 150 and 200 g ANC/kg DM. Each pig served as a replicate unit, housed individually. Bodyweight, feed intake, average daily gain (ADG) and feed conversion ratio (FCR) were recorded weekly throughout the trial period. On completion of the growth trial, following a 3-day adaptation, a nutrient digestibility study was conducted over 5 days. Thereafter, pigs were fasted for twelve hours, weighed, slaughtered, and carcass samples were collected for analysis. Feed intake was not affected by dietary treatment, but ADGs were reduced at ANC levels > 15%, resulting in poor FCR. Protein digestibility was reduced at ANC levels > 15%, while ether extract and fibre levels increased. Warm and cold carcass weights were lower at ANC levels > 15, with improved meat redness and lightness. It was concluded that ANC could replace SBM in the diet of growing pigs at less than 15% inclusion level.

Weaned Pigs

The present experiments were conducted to investigate the effects of dietary chitosan on growth performance, nutrient digestibility, and digestive enzyme activities in weaned pigs. A total of 180 weaned pigs (35 days of age, 11.56 &plusmn; 1.61 kg of body weight (BW)) were selected and assigned randomly to 5 treatments containing 0, 100, 500, 1000, and 2000 mg chitosan per kg feed, respectively. Each treatment involved six replicate pens and six pigs per pen. On days 14 and 28, all pigs were weighed and six from each treatment (one from each replicate pen) were killed, and the contents of the stomach, jejunum, and rectum were collected and used for determining nutrient digestibility and digestive enzyme activity. The results showed that supplementation of chitosan improved quadratically average daily gain (ADG) (P &lt; 0.05). Moreover, dietary chitosan quadratically (P &lt; 0.05) increased apparent digestibility of crude protein (CP) on days 14 and 28, and quadratically increased apparent digestibility of dry matter (DM) on day 14 and of Ca and P on day 28, whereas decreased (P &lt; 0.05) apparent digestibility of ether extract in comparison with the control diet. In addition, dietary chitosan quadratically increased (P = 0.062) amylase activity of proximal jejunum and decreased (P &lt; 0.05) lipase activity of distal jejunum compared with the control. These data indicated that diets supplemented with increasing levels of chitosan (0, 100, 500, 1000, and 2000 mg chitosan per kg) quadratically improved ADG of weaned pigs. The growth-promoting action was achieved probably by improved digestibility of major nutrients (DM, CP, Ca, and&nbsp;P) and increased amylase activity of jejunum. &nbsp;
