Neonatal Programming

Abstract Background The improvement of sow prolificacy by breeding has increased the number of piglets produced per sow per year. However, intrauterine crowding and/or intrauterine growth restriction typically observed in hyperprolific sows impairs foetal growth which has decreased the average individual birthweight, with a larger proportion of low birthweight (LBW) pigs born per litter with poor gut development and compromised postnatal growth performance. Phytogenic compounds (PC) are plant-derived natural bioactive substances that can be used in livestock production as feed additives to promote animal health and production efficiency. This research aims to study if a specific blend of PC (BPC) supplemented in gestating and lactating hyperprolific sow diets may promote pre- and postnatal maternal effects on performance and oxidative status of sows and their offspring, colostrum-milk features, and piglet gut health-related gene expression and morphology. Forty DanBred hybrid line Landrace x Yorkhire gilts and sows (parities 0–7) were randomly allocated by parity number and body weight into two dietary treatments including unsupplemented Control (n = 20) or Control diets supplemented with 1 g/kg feed of BPC (n = 20) throughout gestation and lactation.Results Several dietary PC from the supplemented BPC were transferred to the placental fluid and milk. The BPC supplementation during gestation enhanced the litter size, antioxidant status, and colostrum protein content of sows. Jejunal histomorphology of neonate piglets, and intestinal-function gene expression related to nutrient transport, antioxidant, innate immune response, and digestion were improved in the BPC group. For both, sows and piglets, plasma antioxidant activity of CAT and SOD enzymes were enhanced. For suckling piglets, jejunal expression of genes related to gut barrier function was improved and piglet weight gain from birth to weaning was enhanced in the BPC group.Conclusions Dietary supplementation of BPC in gestating and lactating diets for hyperprolific sows improves sow’s reproductive performance and colostrum composition, with a significant strength of the antioxidant status of sows and their offspring. The prenatal and postnatal maternal transfer (placental fluid and milk) of BPC to the offspring would influence on the neonatal programming and postnatal of piglet’s gut health, with advantageous effects on piglet’s growth performance.

Abstract The response to probiotics and enzymes is often documented in research facilities with a high degree of control and via pigs with no insults to health or feed intake. However, in commercial conditions, the response to feed additives promoting advanced gut health and improved digestion must be consistent and defined over a wide range of health statuses, stocking densities, feed intakes, environments, and diet formulations. The objective of this experiment was to determine if a combined feed protease and probiotic system (Syncra® SWI 201, DuPont, Wilmington, DE) would improve growth performance and mortality under commercial conditions. A total of 127,092 pigs (6.0 ± 0.1 kg; PIC 337 sired, Hendersonville, TN) from a sow farm producing porcine reproductive and respiratory virus and rotavirus positive weaned pigs were placed in 53 2,400-head commercial wean-to-finish barns that were alternated to 1 of 2 treatments (a control treatment without Syncra® SWI (SSWI) or with SSWI included at 72.6 g/ton of finished feed from 22.7 kg of BW to harvest) in a rolling allotment over a 12-month period. Pigs were on the experiment for an average of 162 ± 1.0 days (until harvest). Throughout the 12-month experimental period, diets (outside of the SSWI inclusion) could change in order to maximize return over feed costs. Data were analyzed using Proc MIXED (SAS 9.4; Cary, NC) with treatment as the main effect and barn as the experimental unit. Compared to the control, adding SSWI improved mortality by 1.9% and percent grade 1 marketed pigs by 2.2% (P ≤ 0.025). Compared to the control, SSWI did not improve ADG (control = 0.75 vs. SSWI = 0.78 kg) or gain:feed (control = 0.401 vs. SSWI = 0.396). In conclusion, the inclusion of the SSWI combined feed protease and probiotic system can improve mortality and grade 1 marketed pigs, but not growth performance under commercial conditions.

The Impact

Two experiments were conducted to determine the effects of a fibrolytic enzyme pretreatment on growth performance, apparent total tract digestibility, and ruminal pH throughout the grower and early finisher period (Exp. 1), and to examine the impact of Saccharomyces cerevisiae supplementation on intake, performance, and indicators of gut health in the late finisher period (Exp. 2). Fifty-four steers were randomly assigned to a subgroup determining experimental treatment groups. In Exp. 1, steers were randomized to: control (CON1; no enzyme) or enzyme (ENZ; 0.75 ml kg-1 DM of feed) dietary treatments. Digestibility was improved (P≤0.05) in ENZ steers for DM, CP, NEg, and sugars, but did not affect (P≥0.12) DMI, ADG, or reticulo-ruminal pH. In Exp. 2, the treatments were: control (CON2; no yeast) or yeast (YST; 3.0 g animal-1 daily) supplemented diets. Rumen papillae were collected for mRNA expression of gut barrier function (OCLN, CLDN, ZO1, ZO2) and immune response (TLR2, TLR4, FCAR) genes and histological measurements. YST decreased (P<0.001) DMI by 31%, reduced variation in dry matter intake, and improved feed conversion ratios, but did not impact rumen health mRNA expression or histology measures (P≥0.07). Overall, ENZ improved the digestibility of some nutrients in the grower period, and YST improved feed efficiency, without impacting growth performance or gut health.

Abstract This study was conducted to investigate the effects of a direct-fed microbial (DFM) product (Bacillus subtilis strain DSM 32540) in weaned pigs challenged with K88 strain of Escherichia coli on growth performance and indicators of gut health. A total of 21 weaned pigs [initial body weight (BW) = 8.19 kg] were housed individually in pens and fed three diets (seven replicates per diet) for 21 d in a completely randomized design. The three diets were a corn-soybean meal-based basal diet without feed additives, a basal diet with 0.25% antibiotics (neo-Oxy 10-10; neomycin + oxytetracycline), or a basal diet with 0.05% DFM. All pigs were orally challenged with a subclinical dose (6.7 × 108 CFU/mL) of K88 strain of E. coli on day 3 of the study (3 d after weaning). Feed intake and BW data were collected on days 0, 3, 7, 14, and 21. Fecal scores were recorded daily. On day 21, pigs were sacrificed to determine various indicators of gut health. Supplementation of the basal diet with antibiotics or DFM did not affect the overall (days 0–21) growth performance of pigs. However, antibiotics or DFM supplementation increased (P = 0.010) gain:feed (G:F) of pigs during the post-E. coli challenge period (days 3–21) by 23% and 24%, respectively. The G:F for the DFM-supplemented diet did not differ from that for the antibiotics-supplemented diet. The frequency of diarrhea for pigs fed a diet with antibiotics or DFM tended to be lower (P = 0.071) than that of pigs fed the basal diet. The jejunal villous height (VH) and the VH to crypt depth ratio (VH:CD) were increased (P &lt; 0.001) by 33% and 35%, respectively, due to the inclusion of antibiotics in the basal diet and by 43% and 41%, respectively due to the inclusion of DFM in the basal diet. The VH and VH:CD for the DFM-supplemented diet were greater (P &lt; 0.05) than those for the antibiotics-supplemented diet. Ileal VH was increased (P &lt; 0.05) by 46% due to the inclusion of DFM in the basal diet. The empty weight of small intestine, cecum, or colon relative to live BW was unaffected by dietary antibiotics or DFM supplementation. In conclusion, the addition of DFM to the basal diet improved the feed efficiency of E. coli-challenged weaned pigs to a value similar to that of the antibiotics-supplemented diet and increased jejunal VH and VH:CD ratio to values greater than those for the antibiotics-supplemented diet. Thus, under E. coli challenge, the test DFM product may replace the use of antibiotics as a growth promoter in diets for weaned pigs to improve feed efficiency and gut integrity.

Over Time

Phytogenic feed additives are used in animal feeding to improve livestock performance. The aim of this study was to determine whether a dietary plant extract from Lippia citriodora, standardized for verbascoside, can modify various immunological, oxidative, and biochemical serum parameters in weaned piglets. A total of 144 piglets, half female and half barrows (7.99 &plusmn; 1.40 kg BW), were allocated to three dietary treatments with six replicates per treatment (pens of 8 piglets each). Piglets were supplemented with the following levels of plant extract standardized for verbascoside: 0 (CON = control group), 5 (LV = low verbascoside group), or 10 (HV = high verbascoside group) mg/kg of diet for 56 days. Body weight (BW) and feed consumption were recorded at days 0 and 56 to determine the average daily gain and gain : feed. Twelve piglets from each treatment were randomly selected, and blood was collected by anterior vena cava puncture on days 0, 14, and 56 for glucose, triglycerides, cholesterol, urea, and oxidative status, and on days 0 and 56 for IgG and IgA concentrations. The HV group grew more (P &lt; 0.05) than the CON and LV groups. No significant differences were observed for any of the biochemical parameters between the groups; urea, high density lipoprotein cholesterol, total cholesterol, and low density lipoprotein cholesterol increased significantly over time. Reactive oxygen metabolites (ROM) showed significant time, time &times; treatment, and treatment effects (P &lt; 0.001). Both serum Igs increased (P &lt; 0.005, P &lt; 0.001 for IgG and IgA respectively) over time in all groups; treatment (P &lt; 0.05), and time &times; treatment (P = 0.056) effects were found for serum IgA concentration. The Lippia citriodora verbascoside positively influenced antioxidant status and IgA content with a tendential effect on growth performance. &nbsp;

Abstract Background There is a great demand for antibiotic alternatives to maintain animal health and productivity. The objective of this experiment was to determine the efficacy of dietary supplementation of a blood group A6 type 1 antigen oligosaccharides-based polymer (Coligo) on growth performance, diarrhea severity, intestinal health, and systemic immunity of weaned pigs experimentally infected with an enterotoxigenic Escherichia coli (ETEC), when compared with antibiotics. Results Pigs in antibiotic carbadox or Coligo treatment groups had greater (P < 0.05) body weight on d 5 or d 11 post-inoculation (PI) than pigs in the control group, respectively. Supplementation of antibiotics or Coligo enhanced (P < 0.05) feed efficiency from d 0 to 5 PI and reduced (P < 0.05) frequency of diarrhea throughout the experiment, compared with pigs in the control group. Supplementation of antibiotics reduced (P < 0.05) fecal β-hemolytic coliforms on d 2, 5, and 8 PI. Pigs in antibiotics or Coligo groups had reduced (P < 0.05) neutrophil counts and serum haptoglobin concentration compared to pigs in the control group on d 2 and 5 PI. Pigs in Coligo had reduced (P < 0.05) total coliforms in mesenteric lymph nodes on d 5 and 11 PI, whereas pigs in antibiotics or Coligo groups had reduced (P < 0.05) total coliforms in spleen on d 11 PI compared with pigs in the control group. On d 5 PI, pigs in the Coligo group had greater (P < 0.05) gene expression of ZO1 in jejunal mucosa, but less (P < 0.05) mRNA expression of IL1B, IL6, and TNF in ileal mucosa, in comparison with pigs in the control group. Supplementation of antibiotics enhanced (P < 0.05) the gene expression of OCLN in jejunal mucosa but decreased (P < 0.05) IL1B and IL6 gene expression in ileal mucosa, compared with the control. On d 11 PI, supplementation of antibiotics or Coligo up-regulated (P < 0.05) gene expression of CLDN1 in jejunal mucosa, but Coligo reduced (P < 0.05) IL6 gene expression in ileal mucosa compared to pigs in the control group. Conclusions Supplementation of Coligo improved growth performance, alleviated diarrhea severity, and enhanced gut health in weaned pigs infected with ETEC F18 in a manner similar to in-feed antibiotics.
