Dietary Starch

The present experiment was conducted to dissect the effects of different carbohydrate combinations on the growth performance, nutrient digestibility, and microbial communities in weaned pigs. The combination was optimized by constructing L9(34) orthogonal design. Three factors include starch (amylose to amylopectin (AM/AP) ratio 2:1, 1:1, 1:2), non-starch polysaccharides (NSP) (1%, 2%, 3%, a mixture of inulin with cellulose by 1:1), and mannan-oligosaccharide (MOS) (400, 800, 1200 mg/kg) were investigated and nine combinations were implemented under different levels of these factors. One hundred and sixty-two weaned pigs were randomly assigned to nine dietary treatments with six replicates per treatment and three pigs per replicate. Results exhibited that different combinations of starch, NSP, and MOS affected the gain to feed (G:F) (p < 0.05), diarrhea incidence (p < 0.10), nutrient digestibility (p < 0.05), microbial communities, and short-chain fatty acid (SCFA) concentrations (p < 0.05). In the present study, taking into account three-way ANOVA, range, and direct analysis, we found that the optimal carbohydrate combination was starch AM/AP 1:1, NSP 3%, MOS 400 mg/kg for weaned pigs. Moreover, feeding this combination diet could promote the growth performance and nutrient digestibility, increase the butyrate-producing bacteria, and to some extent improve lipid metabolism. This study provided a novel way to evaluate the carbohydrate quality in swine production.

Abstract The objective was to determine the functional and nutritional values of Corynebacterium glutamicum Cell Mass (CGCM) on growth performance and gut health of newly-weaned pigs. Forty newly-weaned pigs (21 d of age; initial BW 7.1 ± 0.4 kg) were allotted to 5 dietary treatments based on randomized complete block design with sex and BW as blocks. The lysine broth of CGCM (CJ Bio, Fort Dodge, IA) was homogenized by using French press and dried to obtain lysed CGCM. Dietary treatments were: basal diet with lysed CGCM at 0, 0.7, 1.4, 2.1%, and with 1.4% intact CGCM. Experimental diets were formulated based on nutrient requirements (NRC, 2012) and pigs were fed based on 2 phases (10 and 11 d for each phase). Titanium dioxide (0.4%) was added to phase 2 diets as an indigestible external marker to calculate nutrient digestibility. Feed intake and BW were measured at d 0, 10, and 21. Pigs were euthanized on d 21 to collect proximal and distal jejunal mucosa to measure TNF-α, IL-8, MDA, IgA, and IgG concentrations. Diets and ileal digesta were collected to measure AID. Data were analyzed by SAS using MIXED, REG, and GLM procedures. Overall, increasing daily lysed CGCM intake increased (P &lt; 0.05) ADG (211 to 296 g) and ADFI (432 to 501 g). Increasing levels of lysed CGCM decreased (P &lt; 0.05) MDA and changed (quadratic, P &lt; 0.05) IgA (max: 4.90 ng/mg at 1.13%) and IgG (max: 3.37 ng/mg at 1.04%) in the proximal jejunal mucosa. Increasing daily lysed CGCM intake had quadratic effect (P&lt; 0.05) of protein carbonyl (max: 6.3 μmol/mg at 4.9 g/d). Lysed CGCM potentially benefits growth performance and gut health of newly-weaned pigs by reducing oxidative stress and increasing immune response.

Abstract The aim of this trial was to determine the optimal supplementation mealworm on growth performance, apparent total tract retention of nutrients, hematological traits, immune response, and intestinal morphology in weaned pigs. A total of 180 weaned pigs (Landrace×Yorkshire×Duroc; 6.27 ± 0.15 kg) were randomly allotted to 3 treatments and 6 replicates on the basis of initial body weight and sex. The dietary treatments included a corn-based diet supplemented with 0, 2.5, or 5 % mealworm in 2 phases (0–14 and 15–28 d). The gain to feed ratio (G:F) was higher in pigs fed 2.5% mealworm compared with 2.5% during the first phase. Overall ADG was improved in pigs fed 2.5% mealworm compared with pigs fed 5% mealworm. No improvement in overall ADFI and G:F were observed. No digestibility responses were observed by adding mealworm to the diet, but the digestibility of DM and GE were tended to be higher in pigs fed 2.5% mealworm compared with control in phase 1. The number of monocytes tended to be increased in pigs fed 5% mealworm. The concentration of plasma IgG was higher in pigs fed mealworm, however, the plasma IL-6 was tended to be decreased when mealworm was added to the diet (P = 0.052). There was no change in intestinal morphology with increasing dietary levels of mealworm. The results showed that the dietary supplementation of 2.5% mealworm had beneficial effects on growth performance and immune system, however, no effects were detected on growth performance when 5% mealworm was added to the diet.

Abstract The study was conducted to investigate effects of dietary inactivated probiotics on growth performance, nutrient digestibility, and immune responses of weaned pigs. A total of 96 weaned pigs (initial BW = 6.95 ± 0.25 kg) were randomly assigned to 4 dietary treatments with increasing levels of inactive probiotics (4 pigs/replicate; 6 replicates/treatment; 0, 0.1, 0.2, and 0.4%; CON, T1, T2, and T3) in a randomized complete block design (BW and sex as blocks). The inactivated probiotics used in this experiment was a commercial product (CJ CheilJedang Biotechnology Research Institute, Seoul, Korea) containing 1 x 106 CFU/g on stains of Lactobacillus rhamnosus. Pigs were fed respective dietary treatments for 4 weeks. During the last week of the experimental period, pigs were fed their respective dietary treatments containing 0.2% chromic oxide. Fecal samples were collected by rectal palpation daily for the last 3 days after the 4-day adjustment period during the last week of experiment. Blood was collected from randomly selected one pig each pen on d 1, 3, 7, and 14 after weaning. Measurements were growth performance, apparent total tract digestibility (ATTD), TNF-α, TGF-β, CRP, and cortisol by ELISA. Data were analyzed using the MIXED procedure of SAS. The inactivated probiotics increased ADG (471, 501, and 513 vs. 428 g/d; P &lt; 0.05) and G:F (0.65, 0.69, and 0.71 vs. 0.58 g/g; P &lt; 0.05) during overall experimental period compared with CON. The inactivated probiotics increased ATTD of GE (86.87, 87.29, and 88.53 vs. 85.25%; P &lt; 0.05) compared with CON. The inactivated probiotics decreased TNF-α (600, 542, and 523 vs. 849 pg/ml; P &lt; 0.05) and cortisol (5.58, 5.56, and 5.44 vs. 7.25 ng/ml; P &lt; 0.05) on d 7 compared with CON. In conclusion, addition of inactivated probiotics improved growth performance, and nutrient digestibility, and modified immune responses.

One hundred twenty weaned piglets (9.34 ± 0.74 kg) were used in a four-week experiment to investigate the effects of replacing medical ZnO with a different ratio of inorganic and organic zinc (IZ:OZ) or a low-crude-protein diet (LP) with mixed feed additives (MFAs) in the weaned piglets’ diet. The dietary treatments included a control (CON), T1 (T1; ZnO 1000 mg/kg), T2 (IZ:OZ 850:150), T3 (IZ:OZ 700:300), T4 (IZ:OZ, 500:500), and T5 (LP with MFAs (0.1% essential oils + 0.08% protease + 0.02% xylanase)). The growth performance was decreased (p < 0.05) in the CON treatment compared with the T4 treatment. The diarrhea incidence was decreased (p < 0.05) in the T4 and the T5 treatment compared with the CON and the T1 treatments. The apparent total tract digestibility (ATTD) of nutrients were increased (p < 0.05) in the T4 and T5 treatments compared with the CON, T1, and T2 treatments. The T4 treatment had a higher (p < 0.05) ATTD of zinc than the T1, T2, and T3 treatments. The fecal microflora was improved (p < 0.05) in the T5 treatment compared with the CON and T3 treatments. In conclusion, IZ:OZ 500:500 could improve growth performance, nutrient digestibility, and zinc utilization while reducing diarrhea incidence in weaned piglets. Moreover, LP with MFA could replace medical ZnO.

Abstract We previously found that i.m. injection of GRA, similar to in-feed antibiotics, improves measures of intestinal integrity, nutrient digestibility, and overall growth performance in nursery pigs. In addition, we have demonstrated that the mitigating effects of GRA on the stress of weaning is predominantly done by subsiding the inflammatory response that often accompanies early weaning. The objective of the current study was to explore the most practical methods for delivering GRA to newly weaned pigs. One-hundred and sixty-seven PIC pigs were weaned at 25 ±1.0 days of age (BW 7 ±1.2 kg), and assigned to fourteen treatments (3-4 pigs /pen; 3 pens/treatment). Seven treatments were tested within two sexes (gilts vs. barrows). The treatments were: 1) i.m. injection of GRA (two injections, 0.2 mg/kg BW at -1 and 3 d post-weaning), 2) two levels of in-water GRA (0.8 and 1.6 ppm), 3) in-feed GRA (2.5 and 5.0 ppm), 4) in-feed antibiotic (ANT, 100 ppm tylosin), and 5) control. Dexamethasone was used as GRA. Pigs had free access to in-feed or in-water GRA or ANT during the 1st-week post-weaning. Parameters of growth performance were measured weekly until the end of the nursery phase. A completely randomized design and repeated measurement ANOVA (PROC MIXED) in SAS were used for statistical analyses. In-water, in-feed, and i.m. GRA treatments resulted in growth performance outcomes comparable to that of in-feed ANT. Relative to CON pigs, both ANT and GRA improved ADG and G: F during the nursery phase (P &lt; 0.05). Among the delivery methods tested, 2.5 ppm of in-feed GRA resulted in superior ADG (GRA vs. CON; 0.29 vs. 0.20 kg/d) and G: F (0.63 vs. 0.40 ± 0.05), compared to the control group (P &lt; 0.02). Collectively, these results suggested that in-feed treatment is the best method for delivering GRA to newly weaned pigs.

This study was conducted to evaluate the effects of lysine cell mass (LCM) as an alternative lysine source in diets for weaning pigs on growth performance, diarrhea incidence, and blood profiles. In experiment 1, a total of 200 weaning pigs, with an average body weight (BW) of 6.89 ± 1.04 kg, were allotted into one of five treatments with four replicates of 10 pigs per pen in a randomized complete block design (RCBD). The dietary treatments were composed of LCM supplementation (0, 0.25, 0.5, 0.75, or 1.0%) with partial replacement of L-lysine·HCl (0 to 0.8% for phase 1 diets and 0 to 0.07% for phase 2 diets). The BW and feed intake were recorded at the end of each phase (d 0 to 14 for phase 1, d 14 to 35 for phase 2), and diarrhea incidence was checked daily throughout the experimental period. Blood samples were taken from the jugular vein of pigs at 2 weeks and 5 weeks to determine the blood profiles of weaning pigs. In experiment 2, a total of 144 weaning pigs with an average BW of 6.44 ± 1.19 kg were allotted into one of six treatments with six replicates of four pigs per pen in RCBD. The dietary treatments were composed of LCM supplementation (0 to 3.5% for phase 1 diets and 0 to 2.2% for phase 2 diets) with replacement of L-lysine·HCl from 0 to 100%. In experiment 1, partial replacement of L-lysine·HCl with 0 to 1% LCM did not affect growth performance and diarrhea incidence of pigs. An increase in the LCM supplementation from 0 to 1% with partial replacement of L-lysine·HCl had no influence on the blood urea nitrogen concentrations, whereas it resulted in a linear decrease (p < 0.05) in the serum IgG concentrations for 5 weeks. In experiment 2, increasing the dietary level of LCM with replacement of L-lysine·HCl quadratically decreased (p < 0.05) ADG and G–F ratio for phase 2 and G–F ratio for the overall period such that 100% replacement of L-lysine·HCl with LCM decreased ADG and G–F ratio of weaning pigs. An increase in the LCM supplementation with replacement of L-lysine·HCl tended to decrease linearly (p < 0.10) the diarrhea incidence of weaning pigs for the overall period and linearly decrease (p < 0.05) the serum IgG concentrations for 2 weeks. In conclusion, partial replacement of L-lysine·HCl with LCM from 0 to 1% had no negative impacts on the growth performance, but 100% replacement of L-lysine·HCl with LCM decreased the growth performance of weaning pigs. Therefore, LCM could be included in the diets for weaning pigs up to 2.8% and 1.76% for phase 1 and phase 2, respectively, as a substitute for L-lysine·HCl without detrimental effects on the performance of weaning pigs.

The Impact

Abstract A study was conducted to evaluate the effects of a multi-strain Bacillus subtilis-based direct-fed microbial (DFM) on apparent digestibility and colonic pH of nursery pigs. Eighty pigs, of equal number of barrows and gilts (initial BW: 6.99 ± 1.67 kg), were weaned at 21 ± 1 d and randomly allotted to sixteen pens, with five pigs per pen. Two dietary treatments were implemented, a basal control (CON) and a control plus DFM (DFM). Both diets were corn, soybean meal, and distillers dried grains based, formulated to meet all or exceed all nutritional requirements, and manufactured on site. Diets were fed for 42 days. Performance measures were recorded weekly. On d 21 and 42 of the experiment, one pig per pen was randomly selected and euthanized, with equal number of males and females represented. Digestibility of specific nutrients was evaluated within the duodenum, jejunum, ileum, ascending and distal colon. There were no overall differences in growth performance. Overall means ± SD were 0.51 ± 0.05 kg/d, 0.79 ± 0.05 kg/d and 0.66 ± 0.05 for ADG, ADFI, and G:F, respectively. Digestibility of tryptophan within the jejunum tended (P = 0.06) to increase with addition of DFM, as did cysteine (P = 0.12) and methionine (P = 0.10). The analysis also suggested that the impact of the DFM on the digestibility of amino acids may be early in the nursery phase. The pH of contents in ascending colon, a possible indicator of varied fiber digestion, did not differ. Likewise, no differences were observed between treatment in apparent total tract nitrogen and energy digestibility (analysis of distal colon contents). The addition of a multi-strain Bacillus subtilis-based DFM appears to impact digestibility of select amino acids depending upon location in the gastrointestinal tract.

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.
