Forty-eight crossbred pigs of average initial weight 21 kg were fed 10% Tower rapeseed meal (RSM) and 10% Candle RSM as partial replacements for soybean meal (SBM). Diets were formulated to be isocaloric. Pigs fed the SBM diet consumed less feed, gained significantly (P < 0.01) faster and were more efficient at converting feed to gain than those fed the RSM diets. Performance of pigs fed Candle RSM was not significantly different to that obtained with Tower RSM. In a second experiment, dehulled Tower RSM and Tower RSM hulls were mixed in amounts to produce RSM with crude fibre levels of 6.8, 10.8, 13.5 and 15.8%. The simulated RSM and Tower and Candle RSM were used to completely replace SBM in the diets of weanling (75 g) Sprague-Dawley rats. Rats fed SBM had significantly (P < 0.05) higher average daily gain (ADG) than those fed Tower or Candle RSM, or diets containing the rapeseed meats. There was no significant (P < 0.05) difference in ADG, feed intake or feed to gain ratio of rats fed either Tower or Candle RSM. Feed intake, feed to gain ratio and fecal volatile fatty acid concentrations increased while average daily gain decreased with increasing level of hulls in simulated RSM diets. There was no significant difference (P < 0.05) in thyroid weight between rats fed SBM, Tower RSM or Candle RSM.

An experiment was conducted during the late fall and winter months with 96 Yorkshire barrows and gilts to study the effects on pig performance of feeding corn-soybean meal (SBM) and lysine-HCl (0.1%) supplemented corn-SBM-Tower rapeseed meal (RSM) and corn-SBM-Candle RSM diets, in the form of mash (corn was medium-ground) and steam pellets. Average daily gain (ADG), feed intake, efficiency of feed conversion (feed to gain ratio, F/G) and carcass backfat thickness were measured in pigs reared from 23 kg to 91 kg liveweight. The energy level in the RSM diets was not adjusted to equal that in the corn-SBM diet. Pigs fed Tower RSM had a lower (P < 0.01) feed intake and backfat thickness and pigs fed Candle RSM had a lower (P < 0.01) ADG and feed intake and higher (P < 0.01) F/G compared to the pigs fed SBM. The pigs fed corn-SBM-Tower RSM had a higher (P < 0.01) ADG and feed intake and lower (P < 0.01) F/G ratio than those fed Candle RSM diets. Steam pelleting of the corn-SBM and corn-SBM-RSM diets improved ADG, feed intake and F/G of the pigs, with the effects being greatest for the RSM diets.

An experiment was conducted during the spring and summer months with 96 Yorkshire barrows and gilts, to study the effects of feeding corn-soybean meal (SBM), corn-SBM-Tower rapeseed (RSM) and corn-SBM-Candle RSM diets, in the form of mash and steam-processed pellets on average daily gain (ADG), efficiency of feed conversion (feed to gain ratio) F/G), average daily feed intake and carcass backfat thickness of pigs reared from 23 kg to 91 kg liveweight. Tower RSM or Candle RSM at the 15% level in corn-SBM based diets did not result in any adverse effects on ADG, feed intake or backfat thickness, but did increase F/G (P < 0.05). There were no differences in F/G between pigs fed Tower RSM and Candle RSM diets. Steam pelleting enhanced ADG (P < 0.01) and F/G (P < 0.05) across all three diets, but did not affect feed intake or backfat thickness. Barrows had higher (P < 0.01) ADG and backfat thickness than gilts, but did not differ in feed intake or F/G.

Abstract Ambitine Feed Additive (AMB), a proprietary blend of phytogenics and acidifiers (PMI, Arden Hills, MN), is formulated to help mitigate late finishing stress in pigs. Several studies using AMB in the late finishing period resulted in improved pig performance. A meta-analytic method used 13 studies (3 studies with ractopamine and 10 studies without) to determine the overall impact of AMB on average daily gain, average daily feed intake, and feed conversion. The combined data were considered a randomized complete block design. Analysis of variance was completed using the GLIMMIX procedure of SAS (9.4; Cary, NC) and least squares means were compared using Fisher’s least significant difference (P &lt; 0.05). In the analysis of 10 studies with no added ractopamine (73 pens/treatment of 5 to 10 pigs/pen and 48 pens/treatment of 17 to 20 pigs/pen), pigs provided AMB had higher average daily gain (0.90 vs 0.86 kg/d; P &lt; 0.05), increased average daily feed intake (2.99 vs 2.94 kg/d; P &lt; 0.05), and improved feed efficiency (0.30 vs 0.29 kg gain/kg feed intake; P &lt; 0.05) compared to pigs fed control diets. Additionally, when pigs were provided AMB in addition to ractopamine (3 studies; 33 pens/treatment of 18 to 22 pigs/pen), average daily gain was increased 4.7% (1.206 vs 1.152 kg/d; P &lt; 0.05) and feed efficiency was improved 5.3% (0.40 vs 0.38 kg gain/kg feed intake; P &lt; 0.05) compared to pigs provided only ractopamine, with no difference in feed intake. Pigs provided AMB in addition to ractopamine had increased hot carcass weight and dressing percentage (P &lt; 0.05) compared to those provided ractopamine alone. In conclusion, providing AMB to pigs in late finishing improved ADG and feed efficiency and the improvement was maintained when ractopamine was included in the diets.

Abstract OutPace® Feed Additive (OP), contains a carefully researched blend of activated medium chain fatty acids (MCFAs; PMI, Arden Hills, MN), formulated to help mitigate the effects of stress in nursery pigs. Several studies using OP in both late and full nursery periods resulted in improved pig performance. A meta-analysis using 9 studies (4 studies during late nursery [15 to 26.8 kg BW] and 5 studies during the full nursery [5.9 to 25.4 kg]) was done to determine the impact of OP (included at 0.25% Phase 1 and 2; 0.125% Phase 3) on average daily gain, average daily feed intake, and feed conversion. The combined data was considered a randomized complete block design. Analysis of variance was completed with mixed models using the GLIMMIX procedure of SAS (SAS 9.4, SAS Institute Inc., Cary, NC) and least squares means were compared using Fisher’s least significant difference (P &lt; 0.05). In the analysis of 5 studies conducted in late nursery (45 pens/treatment of 6 to 20 pigs/pen), pigs provided OP had higher average daily gain (0.67 vs 0.63 kg/d; P &lt; 0.05), increased average daily feed intake (0.99 vs 0.97 kg/d; P &lt; 0.05), and improved feed efficiency (0.67 vs 0.65 kg gain/kg feed intake; P &lt; 0.05) compared to pigs fed control diets. Additionally, when pigs were provided OP throughout the nursery period (20 pens/treatment of 7 to 20 pigs/pen), average daily gain was increased 6.1% (0.48 vs 0.45 kg/d; P &lt; 0.05), average daily feed intake tended to be increased 2.2% (0.62 vs 0.61 kg/d; P &lt; 0.1), and feed efficiency was improved 2.7% (0.76 vs 0.74 kg gain/kg feed intake; P &lt; 0.05) compared to pigs provided control diets. In conclusion, providing OP to pigs during the nursery period improved ADG and feed efficiency.

ABSTRACTThe effects of feeding monensin and amicloral at 33 and 1500 mg/kg of diet, respectively, were investigated in two experiments using 330-kg steers. Monensin and amicloral, either alone or in combination, increased the digestibility of organic matter and crude fibre compared with a control diet (P< 0·001). Crude protein digestibility was increased by monensin (P< 0·001). Use of monensin and amicloral, alone or in combination, increased molar proportions of propionic acid by 22% on average (P> 0·05), and monensin decreased butyric acid by 37% (P< 0·05).Ruminal ammonia concentrations were lower in steers fed monensin (P< 0·05). Steers fed monensin consumed 6 % less feed, gained 9 % more weight (P< 0·05) and utilized feed 14% more efficiently (P< 0·05) than control animals. Amicloral, either alone or with monensin, lowered feed intake by 11 % (P< 0·05), had no effect on average daily gain and improved feed efficiency by about 12% (P< 0·05). There were no treatment effects on any of the carcass parameters.

Three Phases

Eighty 3- to 4-wk-old crossbred pigs averaging 5.3 kg in weight at allotment were fed experimental diets during starting, growing and finishing phases to compare Tower rapeseed meal (00-RSM) and commercial rapeseed meal (C-RSM) as the sole or partial replacements for soybean meal (SBM). Barley and wheat were the main energy sources with varying amounts of animal tallow to provide isocaloric diets on a digestible energy basis. A 50/50 isonitrogenous combination of 00-RSM + SBM resulted in feed intake, daily gain and feed/gain ratio similar to results with pigs fed SBM as the sole protein supplement during the three phases. Complete substitution of SBM by 00-RSM resulted in reduction (P <.05) of feed intake during the starting phase as well as lower (P <.05) daily gain and inferior (P <.05) feed/gain ratio during the growing phase. Partial substitution of C-RSM for SBM resulted in reduction (P <.05) of feed intake during the starting and finishing phases. Complete replacement of SBM with C-RSM resulted in a depression (P <.05) of daily gain during all three phases of the experiment, inferior feed/gain ratio during the starting and growing phases compared with pigs fed the other four diets and lower (P <.05) feed intake during the starting and finishing phase compared with pigs fed the SBM diet. These findings were confirmed in a rat experiment. Carcass characteristics of pigs were not greatly affected by experimental treatments. A trend of lower digestibility of energy, nitrogen and amino acids was noted by complete replacement of SBM with either source of RSM in the pig and the rat experiments.

Thirty-six Merino lambs (8–9 weeks of age and 15.3 ± 0.13 kg of initial liveweight) were used to evaluate the effects of the inclusion of 120 g sugar beet pulp (replacing barley) and the addition of 20 g sodium bicarbonate per kg concentrate on feed intake, digestibility, animal performance and carcass characteristics in fattening lambs. Animals were housed individually and fed barley straw and the corresponding experimental concentrate feed ad libitum [basal diet composed of (g/kg) barley (500), maize (230), soybean meal (190), molasses (50) and vitamin premix (30)]. Faeces were collected for 5 days to estimate digestibility. Lambs were slaughtered when they reached 25 kg liveweight. Carcasses were chilled at 4°C for 24 h, some carcass dimensions were calculated, the left carcass was jointed into commercial cuts and shoulder tissue composition determined. Sugar beet pulp decreased DM intake (P < 0.05) and average daily gain (P < 0.001), increasing feed : gain ratio (P < 0.001), whereas sodium bicarbonate increased neutral detergent fibre digestibility (P < 0.05) and average daily gain, reducing the feed : gain ratio (P < 0.05). Carcass characteristics were not affected (P > 0.05) by either sodium bicarbonate or sugar beet pulp. Replacing barley with 120 g sugar beet pulp/kg concentrate caused a decrease in DM intake and average daily gain, resulting in an increase in feed : gain ratio, with no detrimental effect on carcass characteristics. The addition of 20 g sodium bicarbonate/kg concentrate improved intake and animal performance without affecting carcass characteristics. Inclusion of sugar beet pulp as a replacement for barley in high-concentrate diets for fattening lambs did not produce performance responses similar to those observed by adding a buffering salt.

Abstract The breakdown of long chain arabinoxylans into smaller chain xylo-oligomers by the use of xylanase results in a shift towards fiber utilizing bacteria resulting in production of small chain fatty acids and improved pig performance. The objective of this study was to evaluate the effect of xylanase (Econase XT; AB Vista) on finisher pig performance. A total of 598 pigs; (37.4 ± 1.0 kg) were fed a single-phase diet for 60 days. Pigs were assigned to two treatments; 0 (CTL) or 16,000 BXU/kg of xylanase (XYL) with 12 pen replicates and 24/25 pigs (mixed sex; gilts and boars) per treatment. The diet was based on wheat, barley, soybean meal, rapeseed meal, and wheat midds; SID Lys: 0.88%, NDF: 14.7%, and NE: 2090 kcal/kg. Average daily gain (ADG), feed intake (ADFI) and feed conversion ratio (FCR) were evaluated in phase 1 (0-26d), phase 2 (26-60d) and overall (0-60d). Liveability was measured per treatment. Data were analysed using JMP 12 using the standard least square platform and ANOVA was performed to determine significance at P &lt; 0.05. The model included initial BW as a covariant. The results indicated that there was no effect of xylanase on liveweight, ADG or ADFI at any phase of the finisher period. The use of xylanase improved FCR in phase 2 (2.53 v 2.60: P &lt; 0.05) and overall (2.44 v 2.49 P=0.03). No differences were seen in liveability (CTL; 96%; XYL 98%; P = 0.29). It can be concluded that the use of xylanase can be used in finisher feeds to improve FCR which is linked with greater energy utilisation that has been associated with greater fiber breakdown through xylanase use.
