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.

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.

Ninety-six Yorkshire barrows and gilts were used in each of two experiments conducted in the spring-summer (exp. 1), and fall-winter (exp. 2) months, respectively, to evaluate 15% Tower rapeseed meal (RSM) as a partial replacement for soybean meal (SBM) on an isonitrogenous basis in corn-based diets for pigs from 23 to 91 kg body weight. At 91 kg, half the number of pigs in each dietary group were slaughtered. Then, three levels of protein (12, 14 and 16%) in both corn-SBM and corn-SBM-RSM diets were fed to the remaining pigs in each group up to a final body weight of 125 kg. The energy level in the RSM diets was not adjusted to equal that in the SBM diets. In the 23- to 91-kg gain period, average daily gain (ADG) (P < 0.01) and backfat (P < 0.05) were lower in the RSM-fed pigs compared to SBM-fed pigs only in exp. 2. From 91 to 125 kg body weight, ADG (P < 0.05), feed intake (P < 0.01) and backfat (P < 0.01) were lower for RSM-fed pigs only in exp. 2. The heavy weight pigs fed RSM diets had a lower (P < 0.01) dressing percentage than SBM fed pigs in exp. 1. Reduction of dietary protein from the 16% fed up to 91 kg body weight to either 14 or 12% in the 91- to 125-kg gain period did not affect performance.

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. Title of the paper. Genetic association between individual feed intake during Performance test and reproductions traits in pigs The present study deals with the estimation of genetic correlations between Performance test traits measured in boars and reproduction traits of their offspring (sibs) of two purebred lines. Performance traits were individual feed intake (FI) recorded by electronic feeder, feed conversion ratio (FCR), average daily gain (ADG) and backfat thickness (BF). Reproduction traits were number of total piglets born (NBT) and born alive (NBA) Data of 4869 young boars, Performance tested between April 1992 and May 1997 and data of 9710 primiparous sows farrowed between June 1994 to November 1998, were observed. Heritabilities of Performance traits recorded on Station were in line 03 (line 04) h2 = 0.24 (0.33), 0.33 (0.33), 0.23 (0.32) and 0.47 (0.53) for FI, ADG FCR and BF, respectively. Heritabilities of reproduction traits such as NBT, NBA were in line 03 (line 04) h2 = 0 05 (0.08) and 0.05 (0.06), respectively. Genetic correlation between individual feed intake and reproduction traits ranged between rg = 0.12 and 0.27. Undesirable genetic correlations were found between reproduction traits and feed efficiency (rg = 0.13 to 0.44), backfat thickness (rg = 0.07 to 0.25) and partly average daily gain (rg = −010 to 0.09). Line 04 showed lowest magnitude of feed intake and highest genetic antagonism between production and reproduction traits. It is suggested that feed intake capacity is a limiting factor for reproduction in line 04 and genetic antagonism between production and reproduction traits increases with reduction in feed intake.

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.

The objective of this work was to evaluate performance, efficiency parameters and phenotypic correlations among measurements of energy efficiency of Nellore cattle selected for post weaning weight and classified according to residual feed intake, calculated by the difference between observed and predicted intake, based on average metabolic body weight and average daily gain. Thus, animals were classified within three groups: high (> mean + 0.5 standard deviation, less efficient); medium (±0.5 standard deviation of the mean); and low (< mean - 0.5 standard deviation, more efficient) residual feed intake. No differences were observed at initial and final body weights, average daily gain and dry matter intake among groups. Animals with low residual feed intake also had greater feed efficiency, feed conversion and partial efficiency of growth and did not differ from the other animals regarding to relative growth rate and Kleiber ratio. Residual feed intake was significantly correlated to feed efficiency (-0.25), feed conversion (0.25), partial efficiency of growth (-0.37) and dry matter intake (0.16) but it did not present significant correlation with body weight (0.04), average daily gain (-0.02), relative growth rate (-0.03) and Kleiber ratio (-0.05). Significant correlations were found between feed conversion and initial body weight (0.34) and average daily gain (-0.46). Partial efficiency of growth presented significant correlation with all other efficiency parameters analyzed. Residual feed intake has high potential in productive efficiency, when compared to the other energy efficiency measurements, being independent of growth and size of the animals.

Abstract Improved genetics in commercial pig production have resulted in larger litter sizes. However this has increased the prevalence of compromised pigs exhibiting inferior birthweights, weaning weights, and lifetime performance. This study aimed to determine the effects of increased sow lactation feed intake on growth of low and average birthweight piglets until 10 wk of age. Low (Low BW; &lt;1 kg) and average (Av BW; 1.3–1.7 kg) birthweight animals were reared in uniformly weighted litters comprising 14 piglets on a foster mother offered either a low (Low FA; max 7.5 kg/d) or high (High FA; max 11 kg/d) feed allowance over a 28- ± 1-d lactation. Piglet performance was monitored from birth until 10 wk of age. Sows offered a High FA consumed 42.4 kg more feed on average than those offered Low FA, resulting in a greater derived milk yield (P &lt; 0.05). Animals of Av BW remained heavier than Low BW pigs throughout the trial (P &lt; 0.05). Piglets reared by High FA sows were heavier at weeks 3, 4, 5, and 7 (P &lt; 0.05) but not week 10 (P &gt; 0.05). Growth rate of piglets relative to their birthweight was significantly greater for Low BW piglets than those of Av BW during lactation (P &lt; 0.001). Piglets reared by sows offered a High FA expressed greater relative growth preweaning (P &lt; 0.05); however, postweaning relative growth for piglets reared on sows offered a Low FA was greater (P &lt; 0.05) suggesting compensatory growth. Neither birthweight nor sow feed allowance significantly affected preweaning mortality (P &gt; 0.05). However, Low BW animals on sows with a High FA recorded half the preweaning mortality of Low BW pigs on sows with a Low FA. During week 1 of lactation, Av BW litters recorded a greater total suckling duration compared to Low BW litters (P &lt; 0.05) but there was no difference in suckling frequency (P &gt; 0.05). During week 3 of lactation, High FA litters displayed a significantly lower suckling frequency (P &lt; 0.05) yet a greater total suckling duration (P &lt; 0.001). Average daily gain was greater for Av BW pigs during weeks 4–7 (P &lt; 0.001) but no difference was recorded between weeks 7 and 10 (P &gt; 0.05). Average daily feed intake was greater for Av BW pigs throughout the nursery period (P &lt; 0.05) but feed–conversion ratio did not differ compared to Low BW pens (P&gt;0.05). In conclusion, offering sows a High FA increased weaning weight of all animals; however, birthweight was the major determinant of postweaning performance.
