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.

Twenty-four (24) indigenous growing pigs were selected and randomly divided into 4 treatment groups consisting of 6 animals in each group penned individually and provided with the facility of separate feeding and watering to each pig. Sweet potato (Ipomoea batatas) meal (roots and leaves at 1:1 ratio) was incorporated in the diet to replace standard pigs grower ration at 0% (G1), 25% (G2), 50%(G3) and 75% (G4). During the feeding trial of 90 days, it was observed that the average dry matter intake was higher in G2 followed by G3 and G1 being the lowest. The feed conversion efficiency and average daily gain decreased as the level of sweet potato meal increased. However there were no significant differences (P>0.05) among the different treatment groups in regards to feed conversion efficiency and average daily gain. From the digestibility trial, no significant differences (P>0.05) were observed in the digestibility co- efficient of dry matter, crude protein and crude fibre among the different treatment groups. It is concluded that sweet potato meal can replace standard pig grower ration up to 75% without any adverse effect on growth, feed conversion efficiency and nutrient utilization.

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.

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.

The objective of this experiment was to evaluate the effects of metabolizable energy (ME) levels in diets with high digestible lysine concentration on performance, carcass traits, and meat quality of barrows from 95 to 158 days of age. Eighty commercial hybrid barrows (50 ± 1.82 kg) selected for lean meat deposition, were assigned to four dietary treatments (3,150, 3,235, 3,320, and 3,400 kcal EM kg-1) in a randomized design with 10 replicate pens per treatment and two pigs per pen. From 95 to 116 days of age, we observed no effects of ME on final body weight (FBW), average daily gain (ADG), metabolizable energy intake (MEI), and feed conversion (F: G). Average daily feed intake (ADFI) decreased linearly with increasing ME levels (? = 5.79961 - 0.00096790X - r2 = 0.89). From 95 to 137 days of age, no effects of ME were observed on final body weight (FBW), average daily gain (ADG), metabolizable energy intake (MEI), and feed conversion (F: G). Average daily feed intake (ADFI) decreased linearly with increasing ME (?= 6.1176 - 0.001X - r2= 0.97). From 95 to 158 days, of age no effects of ME were observed on FBW and ADG. Dietary ME influenced the ADFI and F: G, which decreased linearly with increasing ME concentrations (?= 8.12951 - 0.00149X - r2= 0.99; ?= 6.0914 - 0.001X - r² = 0.75, respectively). There was a linear increase in loin eye area (LEA) with increasing ME (? = - 29.851 + 0.0207 X - r² = 0.87). Backfat thickness, pH, and temperature, measured at different times after slaughter (0 min, 45 min, 3 h, and 24 h), were not affected by dietary ME. The level of ME also did not affect the meat quality parameters Color L*, Color a*, Color b*, Warner-Bratzler shear force, thaw water losses, cooking water losses, sum of water losses, intramuscular fat content, and TBARS. Diets with 3,400 kcal kg-1 ME, corresponding to 2.75, 2.57, and 2.31 g digestible lysine/Mcal of ME for pigs from 95 to 116, 116 to 137, and 95 to 158 days of age, respectively, resulted in best performance and carcass traits, without negative effects on meat quality.
