Abstract Using alternative feedstuffs can be a feasible measure to reduce swine production cost. GuarPro F-71, a newly developed guar meal product, is considered as a potential protein source for pigs. This study was conducted to evaluate the effects of dietary GuarPro F-71 inclusion on growth performance and nutrient metabolism of growing pigs. Sixty crossbred barrows (31.9 ± 1.84 kg BW) were allotted to 5 dietary treatments according to a completely randomized experiment design with 4 pens/treatment and 3 pigs/pen. Diet 1 was a corn-and-soybean-meal based diet with nutrient composition following NRC (2012) recommendations. GuarPro-71 was used to replace 25%, 50%, 75%, and 100% of soybean meal (on equivalent CP basis) in Diet 1 to generate Diets 2, 3, 4, and 5, respectively. Crystalline amino acids were used to balance the essential amino acid concentrations across the 5 diets. Dietary inclusion of GuarPro-71 reduced ADFI (P < 0.01), whereas no clinical signs of unhealthiness of pigs were observed. The magnitude of ADFI reduction showed linear but also quadratic relationships (P < 0.05) with the GuarPro-71 inclusion rate. The blood plasma concentrations of six metabolites (urea nitrogen, total protein, albumin, glucose, total cholesterol, and total triglycerides) were not affected (P > 0.30), indicating that the pigs’ metabolic utilization of nutrients was not compromised. The cubic effect (P < 0.05) of dietary GuarPro-71 inclusion on the G:F suggests that the level of soybean meal replacement up to 75% by GuarPro-71 did not negatively affect feed efficiency in pigs. In short, the feed intake reduction due to the dietary GuarPro-71 inclusion should be, if not solely, responsible for the ADG and final BW reduction. Overall, this study suggests that the dietary inclusion of GuarPro-71 can negatively affect ADFI and ADG in growing pigs. The reason for the ADFI reduction warrants further investigation.

Nutrient Metabolism

Using alternative feedstuffs can be a feasible measure to reduce swine production cost. GuarPro F-71 (GP71), a newly developed guar meal product, is considered as a potential protein source for pigs. This preliminary study was conducted to evaluate the effects of GP71 inclusion in feed on growth performance and nutrient metabolism of growing pigs. Sixty crossbred barrows (31.9±1.84 kg body weight (BW)) were allotted to one of five dietary treatments in a completely randomised experiment design, with four pens/treatment and three pigs/pen. Diet 1 was a maize- and soybean-based basal control diet formulated to meet NRC recommendations. GP71 was used to replace 25, 50, 75, and 100% soybean meal in diet 1 (on an equivalent crude protein (CP) basis) to generate diets 2, 3, 4, and 5, respectively. Crystalline amino acids were used to balance the essential amino acid concentrations across the five diets. Inclusion of GP71 quadratically reduced average daily feed intake (ADFI) (P=0.01) with no observed clinical signs of unhealthiness of pigs. The blood plasma concentrations of six metabolites, including urea nitrogen, total protein, albumin, glucose, total cholesterol and total triglycerides, were not affected (P>0.30), indicating that the pigs’ metabolic utilisation of nutrients was not compromised. The cubic effect (P<0.05) of dietary GP71 inclusion on G:F ratio suggested that the level of soybean meal replacement (up to 75% soybean meal) did not negatively affect feed efficiency in pigs. In short, the feed intake reduction due to the dietary GP71 inclusion was, if not solely, responsible for the average daily gain (ADG) and final BW reduction. This study suggested that using GP71 to replace soybean meal up to 75% (on an equivalent CP basis) can negatively affect ADFI and ADG, but not feed efficiency, in growing pigs. The reasons for the ADFI and ADG reduction need to be understood in future research.

Abstract An experiment was conducted to determine the effects of L-Lys HCl inclusion in diets with or without distillers dried grains with solubles (DDGS) on growth performance of finishing pigs. A total of 2,414 pigs (initial BW = 92.7 kg) were used in a 34-d trial. Treatments were arranged as a 2 × 3 factorial treatment structure with two levels of DDGS (0 or 10%) and three levels of L-Lys HCl (0.2, 0.3, or 0.4%). Diets were corn and soybean meal-based and were formulated to be isocaloric (NE = 2,668 kcal/kg) and isolysinic (0.75% SID Lys) by adjusting the inclusion of soybean meal, crystalline amino acids, and choice white grease. All other nutrient levels met or exceeded the NRC (2012) requirement estimates. There were 16 replicates per treatment. Pigs were weighed and feed disappearance measured to calculate ADG, ADFI, and G:F. Data was analyzed with SAS MIXED procedure. There was no evidence (P &gt; 0.10) for interactive effects between L-Lys HCl and DDGS inclusion rate. Pigs fed diets with 10% DDGS had improved (P = 0.002) G:F, but there was no evidence (P &gt; 0.10) for differences in ADG or ADFI. Pigs fed increasing levels of L-Lys HCl had higher (linear, P = 0.026) ADFI, decreased (quadratic, P = 0.013) G:F, and a tendency for quadratic response (P = 0.063) in ADG, overall with the poorest performance observed for pigs fed the diet with 0.4% L-Lys HCl. In conclusion, pigs fed 0 or 10% DDGS presented similar performance; however, pigs fed the high level of L-Lys HCl presented decreased performance.

The study aimed to evaluate growth performance of grower pigs fed fermented liquid potato hash with or without exogenous enzyme. Diets containing either 200 (LFLPH) g/kg potato hash (enzyme treated or not); 400 (HFLPH) g/kg potato hash (enzyme treated or not) or no fermented potato hash (control) were formulated to provide 14 MJ/kg digestible energy (DE), 180 g/kg crude protein (CP) and 11.6 g/kg lysine. Dietary treatments were control (no FLPH), enzyme treated LFPHE and HFLPHE, and untreated LFLPH and HFLPH. The exogenous enzyme was added in treated diets to provide minimum of 560-840 TXU/TDU xylanase per kg feed, at an inclusion rate of 100 g/tonne. Diets were mixed with water at 1:2 ration and fermented for 8 hours at 25 °C room temperature before being fed to pigs. Back-slopping fermentation approach was followed to prepare diets. Twelve pigs (25±2.3 kg) per diet that were individually housed were fed ad-lib for eight weeks. Pigs were allocated to diets in complete randomized design. Average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) were measured. The enzyme treated FLPH diets had higher (P < 0.05) CP, lower (P > 0.05) NDF and ADF concentrations compared to untreated FLPH diets. The LFPHE diet had higher (P < 0.001) final weight, ADG and lower (P < 0.001) ADFI and FCR compared to LFPH, HLFPH and HLFPHE. It was concluded that LFPHE diet may be an alternative feed source for growing pigs as indicated by higher gain and lower intake compared to LFLPH, HFLPH and HFLPHE.

Abstract Dry extruded-expelled soybean meal (DESBM) is an attractive feed ingredient for swine not only as a protein source but also as a good source of energy because of its high fat content. Apparent (AID) and standardized (SID) ileal amino acid (AA) digestibility in DESBM fed without or with organic acid (OA) and a multicarbohydrase (MC) supplementation to growing pigs were determined. Ten ileal-cannulated barrows (17.3 ± 0.4 kg BW) were randomly assigned to 1 of 5 dietary treatments in a replicated 5 × 4 incomplete Latin square design with 4 periods, each consisting of 5 d of adaptation and 2 d of ileal digesta collection. Four cornstarch-based diets with 44.4% DESBM as the only source of AA, without or with OA and MC supplementation, and a 5% casein-cornstarch diet were used. All diets contained 0.3% titanium dioxide. Data were analyzed using the MIXED model procedures of SAS, with the final model including OA, MC, and the interaction between OA and MC as the main effects. The SID of indispensable AA in DESBM fed to growing pigs were: Arg, 93.2%; His, 85.1%; Ile, 87.1%; Leu, 87.6%; Lys, 88.7%; Met, 87.8%; Phe, 88.4%; Thr, 81.4%; Trp, 73.6%; Val, 84.5%. OA supplementation decreased the AID and SID (P &lt; 0.05) of Arg, Ile, Asp, and Glu, and tended (P &lt; 0.10) to decrease the AID and SID of Phe, Trp, Cys, Gly, and Tyr. MC supplementation did not affect the AID and SID of AA, and no interactive effect on AA digestibility was observed between OA and MC supplementation. In conclusion, dietary supplementation of OA and MC showed no positive effects on improving AA digestibility in DESBM fed to growing pigs.

Abstract Two experiments were conducted to determine the effects of increasing levels of soybean meal (SBM) replacing feed grade amino acids in corn or corn-dried distillers grains with solubles (DDGS)-based diets on growth performance of late finishing pigs. In both experiments, there were 22 to 27 pigs per pen and 14 pens per treatment. Average length of the experiments was 35 (Exp. 1) and 29 days (Exp. 2). Diets were balanced to contain 0.70% SID Lys and 2,667 or 2,610 kcal NE/kg for Exp. 1 and 2, respectively. Minimum amino acid ratios relative to Lys were: Ile, 55; Met&Cys, 60; Thr, 65; Trp, 19.5, and Val, 70. Dietary crude protein ranged from 10.1 to 15.2 for Exp. 1 and 13.6 to 19.4 for Exp. 2. The statistical model considered fixed effects of treatment, linear and quadratic contrasts, and random effect of block. In Exp.1, 1,793 pigs (L337×1050, PIC; initially 104.9 ± 1.4 kg) were fed corn-based diets and pens of pigs were assigned to 1 of 5 dietary treatments with increasing SBM from 5 to 20%. Overall, average daily gain (ADG) and gain-to-feed (G:F) increased (linear; P &lt; 0.05) as SBM increased with the greatest improvement observed as SBM increased from 5 to 8.75%, with little improvement thereafter. In Exp. 2, 1,827 pigs (L337×1050, PIC; initially 97.9 ± 1.1 kg) were used in a similar study as Exp. 1, but all diets contained 25% DDGS and SBM levels increased from 0 to 16%. Overall, G:F and final bodyweight of pigs marginally improved (linear and quadratic, respectively; P &lt; 0.10) as SBM increased, with the greatest performance observed when diets contained 8% SBM. These results suggest that increasing SBM up to 8% at the expense of feed grade amino acids in corn or corn-DDGS-based diets improved ADG or G:F in late-finishing pigs.

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 This study was aimed to explore the effect of using cassava as an amylopectin source in low protein (LP) diets on growth performance, nitrogen efficiency and postprandial changes in plasma glucose and related hormones concentrations of growing pigs. Three animal experiments were included in the present study. Treatments included corn-soybean meal LP (Corn LP), corn-cassava-soybean meal LP (Corn + Cassava LP), and cassava-soybean meal LP (Cassava LP). The in vitro digestion proved that Corn + Cassava LP and Cassava LP diets induced more rapid starch digestion and glucose release, compared with Corn LP diet. The results of animal experiments are as follows: Cassava LP diet caused the most rapid changes in plasma glucose and relevant hormones concentrations after a meal. And it decreased the concentrations of fasting plasma insulin, glucagon, and leptin concentrations compared with other treatments (P &lt; 0.05). These modulationes above led to a strong desire to eat and increased feed intake and then weight gain in growing pigs fed Cassava LP diet. Besides, feeding Cassava LP diet caused diarrhea, increased noxious gas release from feces, and increased concentrations of fecal isobutyrate and isovalerate (P &lt; 0.05). Compared with Corn LP group, Corn + Cassava LP group showed significantly decreased urinary nitrogen (P &lt; 0.05) and improved post-absorptive amino acid utilization efficiency. In conclusion, the use of cassava as an amylopectin source in LP diets could modulate glucose absorption and related gut secreted hormones secretion, subsequently strengthened the desire to eat, improved growth performance, and enhanced nitrogen efficiency in growing pigs.

Abstract Two experiments were carried out to determine a time-series effect of phytase on phosphorus (P) utilization in growing and finishing pigs using growth performance, apparent total tract digestibility (ATTD) of nutrients, P excretion, and plasma concentrations of minerals as the response criteria for evaluation. In both experiments, treatments were arranged as a 3 × 4 factorial in a randomized complete block design with 3 corn–soybean meal-based diets including a P-adequate positive control (PC), a low-P negative control (NC; no inorganic P), and NC supplemented with phytase at 1,000 FYT/kg (NC + 1,000); and 4 sampling time points at days 7, 14, 21, and 28 in experiment 1, and days 14, 26, 42, and 55 in experiment 2. In both trials, 96 growing pigs with average body weight (BW) of 19.8 ± 1.16 and 49.8 ± 3.21 kg, respectively, were allocated to the 3 diets with 8 replicates pens (4 barrows and 4 gilts) and 4 pigs per pen. In experiment 1, pigs fed the PC had higher (P &lt; 0.01) BW, average daily gain (ADG), average daily feed intake (ADFI), and gain-to-feed ratio (G:F) when compared with pigs fed the NC. There was an interaction (P &lt; 0.01) between time and diet on the BW and ADG of pigs while a linear and quadratic increase (P &lt; 0.01) was observed with the ADFI and G:F, respectively, over time. Phytase supplementation improved (P &lt; 0.01) all growth performance responses. Pigs fed the PC had greater (P &lt; 0.01) ATTD of P and Ca than pigs fed the NC. There was no interaction effect on the ATTD of nutrients. Phytase addition improved the ATTD of P and Ca over pigs fed the NC. There was an interaction (P &lt; 0.01) between diet and time on the total and water-soluble P (WSP) excreted. There was a quadratic decrease (P &lt; 0.01) in plasma concentration of Ca in pigs over time. In experiment 2, there was a quadratic increase (P &lt; 0.01) in BW, ADG, and G:F of pigs over time. Similarly, the inclusion of phytase improved (P &lt; 0.05) all growth performance parameters except ADFI. A linear increase (P &lt; 0.05) in the ATTD of DM, P, and Ca occurred over time. Phytase inclusion improved (P &lt; 0.01) the ATTD of P and Ca. Plasma concentrations of P were improved by phytase addition. Phytase supplementation of the NC reduced WSP excretion by 45%, 32%, and 35% over the growing, finishing, and entire grow-finish period, respectively. In conclusion, phytase improves the utilization of P in growing and finishing pigs; however, the magnitude of effect on responses may vary over time.
