The present study was conducted to evaluate the effects of replacing corn with brown rice on growth performance, nutrient digestibility, carcass characteristics, and gut microbiota of growing and finishing pigs. A total of 100 growing pigs (23.80 ± 2.96 kg BW; 10 weeks of age) were randomly allotted to 4 dietary treatments (5 pigs/pen; 5 replicates/treatment) in a randomized complete block design (block = BW) as follows: corn-soybean meal basal diet (CON) and replacing corn with 50% (GBR50), 75% (GBR75), and 100% (GBR100) of ground brown rice. Each trial phase was for 6 weeks. During the growing period, there were no differences on growth performance and nutrient digestibility among dietary treatments. Similarly, no differences were found on growth performance, nutrient digestibility, and carcass characteristics of pigs during the finishing period among dietary treatments. As a result of the beta diversity analysis, microbial populations were not clustered between CON and GBR100 during the growing phase, but clustered into two distinct groups of CON and GBR100 during the finishing phase. In conclusion, brown rice can be added to the diets of growing-finishing pigs by replacing corn up to 100% without negatively affecting growth performance of the pigs; additionally, this may have an effect on changes in pig intestinal microbiota if continued for a long time.

Abstract The objective of this study was to evaluate the relative bioavailability (RBV) of l-Lys sulfate in comparison to l-Lys HCl based on the growth performance response from approximately 26 to 48 kg and from approximately 68 to 114 kg. The effect of Lys source on blood urea nitrogen (BUN), digestibility of dry matter (DM) and sulfur (S), as well as carcass characteristics was determined. A total of 280 growing pigs (25.9 ± 0.25 kg BW) were randomly assigned to one of seven dietary treatments in 56 pens, with five pigs per pen. The diets included a Lys-deficient basal diet (65% of requirement) and the basal diet supplemented with three graded levels of Lys (75%, 85%, and 95% of requirement), as either l-Lys HCl (78.8% Lys purity) or l-Lys sulfate (54.6% Lys purity). The experiment lasted for 112 d, with four dietary phases: Phase 1 lasted for 4 wk (BW: 25.9 to 47.5 kg), Phase 2 lasted for 3 wk (common commercial diet as washout period), Phase 3 lasted for 5 wk (BW: 67.5 to 98.2 kg), and Phase 4 lasted for 3 or 4 wk to reach an average market weight of 114.2 kg. Fresh fecal samples of pigs fed the highest levels of Lys (both Lys sources) were collected on 7 to 10 days after the beginning of Phase 3 for digestibility assay. Blood samples were collected on day 21 and day 81 to determine BUN. Carcass data were collected at a commercial packing plant. Data were analyzed using PROC GLM of SAS (9.4) according to a completely randomized design with pen as the experimental unit. The RBV of l-Lys sulfate was determined using the multiple regression slope-ratio method. Increasing levels of Lys, independent of source, increased (P < 0.05) BW, ADG, and feed efficiency during Phases 1, 3, and 4; market BW increased linearly (P < 0.01) and backfat and BUN decreased linearly (P < 0.01). Lysine source had no impact on growth performance, carcass characteristics, BUN, or digestibility of S and DM. The RBV of l-Lys sulfate compared with l-Lys HCl was also not different based upon ADG or G:F during Phase 1, 3, or 4. These data suggest that the bioavailability of Lys in l-Lys sulfate and l-Lys HCl is at least equivalent for growing–finishing pigs.

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.

Abstract ValiMP® is a mixture of phytochemical compounds containing manganese. An experiment was carried out to evaluate the effects of ValiMP® on growth performance, carcass characteristics, and pork quality in growing-finishing pigs. The trial was conducted in a 2x3 factorial design with two levels of CP (LP, 15% or HP, 16%), and three types of supplements (Control; 10 ppm ractopamine; or 0.25% ValiMP®). Dietary treatments were: LC (Low CP+control), LR (Low CP+ractopamine), LV (Low CP+ValiMP®), HC (High CP+control), HR (High CP+ractopamine), HV (High CP+ValiMP®). A total of 144 growing pigs at 50 kg initial body weight (BW) were allotted and fed one of the experimental diets for 70 days. But ractopamine in LR and HR treatments was supplemented during the last 35 days. BW and feed intake were measured weekly, and pork quality was determined in longissimus dorsi muscle. All values were statistically analyzed using ANOVA procedure of SAS 9.4 software and differences at P < 0.05 level were considered significantly different. Results showed dietary ractopamine or ValiMP® supplementation numerically promoted growth performance compared to control in HP treatments, although the extent was lesser in ValiMP® treatment. Ractopamine or ValiMP® also improved carcass composition in HP compared to LP. Lean percentage in HR was higher than in LR by 4.3%, and it was greater in HV than in LV by 5.9%, (P < 0.05). These changes occurred at the expense of fat percentage (P < 0.05). Among pork quality criteria, water-holding capacity determined by filter-paper fluid uptake method was significantly lower in HV than those in HC and HR (P < 0.05). Warner-Bratzler shear force, an indicative for meat tenderness, exhibited lower values in HV and HC than that in HR (P < 0.05). Overall, our results suggest ValiMP® improves growth performance and carcass composition with lesser extent to ractopamine, and pork quality more than ractopamine.

Abstract The aim of this study was to evaluate the effect of the inclusion level of crude glycerin from palm oil in the diet of growing pigs. Diets were formulated to be isocaloric and isoproteic, with a constant content of linoleic acid within the experimental diets. A total of 36 pigs (average BW 23.05± 2.86 kg) were randomly assigned to one of the three treatments: 1) 0% of crude glycerin; 2) 5% of crude glycerin; 3) 10% of crude glycerin. Pigs were housed in 12 pens; 4 replicates (pens) per treatment and three pigs/replicate. Data were analyzed as a complete block design using the GLIMMIX procedure of SAS, with a random block effect for period. This study established that inclusion of crude glycerin from palm oil in the diet of growing pigs did not affect (P > 0.05) growth performance, carcass characteristics and meat quality. We concluded that inclusion of crude glycerin from palm oil up to 10% of the diet did not adversely affect pig performance and the quality of the meat.

AbstractA trial was conducted to compare the growth performance and carcass characteristics of 720 growing pigs housed in one of three different finishing systems: outdoor paddocks, straw yards and fully slatted pens. Two genotypes were used: ‘indoor’ (progeny of Large White ✕ Landrace sows mated to Large White boars) or ‘outdoor’ (progeny of part-Duroc or part-Meishan sows, mated to Large White boars). Groups of 20 pigs were reared from an average of 30 to 80 kg live weight and given ad libitum access to a commercial specification diet. The outdoor genotypes had significantly lower average daily gain than the indoor genotype (682, 673 and 719 g respectively for part-Duroc, part-Meishan and indoor-type pigs, P 0·01). Part-Meishan genotypes had significantly higher backfat levels than the indoor genotype (P 0·05), with an intermediate value for part-Duroc pigs (22·6, 21·1 and 21·8 mm respectively). Values for food conversion ratio were significantly higher for combined outdoor genotype groups when compared with the indoor genotype (2·76 v. jt>2·62, P 0·05). Average daily gains of pigs in straw yards and outdoor paddocks were significantly higher than for those in fully slatted pens (736 and 675 v. 627 g, P 0·01 respectively). Food conversion ratio was similar for pigs in outdoor paddocks and fully slatted pens, but significantly lower for those in straw yards (2·77 and 2·75 v. 2·55, P 0·01 respectively). Backfat depth (P1 + P3mm) was significantly greater for animals finished in straw yards compared to those in outdoor paddocks (22·2 v. 20·6 mm, P 0·05) and intermediate for those finished in fully slatted pens (21·5 mm). Interaction between finishing system and genotype did not occur to any major degree, hence it appears unnecessary to specify a particular genotype for a particular finishing system. It was concluded that pigs of the outdoor genotype had a lower growth performance compared with the indoor genotype. Finishing systems however may have been confounded by other factors so that no clear recommendations can be made as to the optimum finishing system.
