    Abstract: Sow longevity plays an important role on the profitability of any sow operation in economically and efficiently producing pigs. An experiment was conducted to evaluate the effects of a synbiotic (Biomin® PS, BIOMIN America Inc.) containing multi-strain live probiotic strains (Enterococcus faecium, Pediococcus acidilactici, Bifidobacterium animalis, and Lactobacillus reuteri) and a prebiotic (fructo-oligosaccharaide) on sow reproductive performance. A total of 24 sows (4th and 5th parity) were divided evenly into 2 groups and fed either a control diet or a synbiotic diet during the gestation (starting on d 35 of gestation) at 1 kg/MT and lactation until weaning of piglets at 0.5 kg/MT. Daily sow feed intake was also measured during the lactation period. Sow BW was recorded pre-farrow (d 110 of gestation) and at weaning (d 21 of lactation). Piglet BW was recorded after cross-foster and on d 21 of lactation. Data were analysed using MIXED model in SAS. No significant difference was observed in sow feed intake. Relatively lower weight loss (14%) was observed during lactation in sows fed synbiotic (-24.3 kg/sow) in comparison to control fed sows (-28.4 kg/sow), although not statistically significant. A positive trend (P 〈 0.10) was observed with synbiotic fed sows having lower still-borns (-50%), increased number of piglets weaned per sow (+0.94 piglet/sow) and litter weight gain (+7.24 kg/litter) compared to control sows during lactation. Weaned litter weight was also increased (P 〈 0.05) with synbiotic feeding (78.5 kg/sow) in comparison to control (66.5 kg/sow). Overall, supplementation of the synbiotic formulation increased the sow reproductive performance by increasing weaned litter weight and number of pigs weaned while numerically lowering sow weight loss during lactation. Supplementation this synbiotic could be considered as part of sow feeding programs to improve sow reproductive efficiency.

    Abstract: A total of 535 sows and their progeny (PIC 359×1050) were used to determine the effect of feeding gestating and lactating sows a proprietary strain of Pichia guilliermondi as a whole-cell inactivated yeast product (WCY; CitriStim, ADM Animal Nutrition, Quincy, IL) on sow and litter performance in a commercial production system. Within 24 hours of breeding, sows were allotted to 1 of 2 dietary treatments. Parity distribution was equalized across treatments. Sows were fed either a basal gestation control (CON) diet or CON fortified with 0.1% (0.91 kg/ton) of the WCY at the expense of corn throughout gestation. Sow dietary treatments were also maintained through lactation. Of the 535 sows that completed the initial reproductive cycle (cycle 1), 358 sows were maintained on dietary treatment and followed through a second gestation and lactation (cycle 2). The direction and magnitude of the differences in total born and born alive pigs in cycle 1 and cycle 2 was similar between treatments. Supplementing sows with WCY in cycle 1 increased the number of total born pigs by 0.59 pigs/litter (P=0.038) and tended to increase the number of pigs born alive by 0.52 pigs/litter (P=0.064) compared to CON fed sows. For cycle 2, the total number of born and born alive pigs numerically increased by 0.44 pigs/litter (P=0.180) and 0.43 pigs/litter (P=0.179) respectively for sows fed WCY. The distribution of pig birth weights was not different between treatments in cycle 1 (P=0.536) nor cycle 2 (P=0.256). Also, the litter growth rate on a weight gain per pig per day basis was not different between treatments in cycle 1 (P=0.103) nor cycle 2 (P=0.379). In conclusion, feeding gestating and lactating sows a proprietary strain of Pichia guilliermondi as a whole-cell inactivated yeast product significantly increased the number of total born pigs during cycle 1.

    Abstract: The objective of this study was to evaluate the vitamin D3 (vitD) and 25-hydroxy vitamin D (25-OHD) requirements for finisher pig performance and bone density. Seventy-two pigs (62 ± 11.1 kg BW) were allotted to 36 pens (n = 2 pigs/pen) and across 4 dietary treatments (n = 9 pens/trt) for 51 d. Corn-soybean meal mash diet treatments were: 1) Diet containing 75 IU/kg vitD; 2) Diet containing 150 IU/kg vitD (NRC requirement); 3) Diet containing 750 IU/kg vitD; and 4) As 1 plus 0.0125% 25-OHD to achieve total diet equivalent of 750 IU/kg vitD. Pigs were weighed and feed disappearance recorded at the start and end of the study to calculate ADG, ADFI and G:F. Serum 25-OHD concentrations were determined on d 42. On d 51, one pig per pen was euthanized and bone mineral density determined on the rib, tibia and fibula. Data were analyzed as a complete randomized design with pen as the experimental unit. Overall, ADG did not differ between treatments 1 through 4 (1.26, 1.31, 1.34, 1.27 kg/d, respectively (P & gt; 0.05). Further, ADFI did not differ between treatments (P & gt; 0.05). However, G:F tended to increase as dietary vitD concentrations increased (0.34, 0.36, 0.37 and 0.35, respectively, P = 0.068). Rib, fibula and tibia bone mineral density did not differ between treatments (P & gt; 0.05). Serum 25-OHD concentrations were 9.9, 11.9, 23.3 and 36.6 ng/mL for treatments 1-4, respectively (P & lt; 0.001). In conclusion, vitamin D3 deficiency was not achieved with treatment 1 in finishing and all treatments had equal pig performance and bone mineral density. Further, 0.0125% 25-OHD provided equal performance and bone density to 750 IU/kg of vitamin D3.

    182 Influence of β-mannanase in the lactation diet on sow and litter performance and subsequent wean-to-service interval
    Oxford University Press (OUP) ; 2019

    Abstract: β-mannans (β-galactomannans) are anti-nutritive fibers found in common feed ingredients, such as soybean meal and other vegetable proteins. If not controlled, these β-mannans cause unnecessary gut inflammation which diverts nutrients from production to maintenance. Hemicell® HT has been shown to breakdown β-mannans allowing energy and nutrients to be available for growth and performance. The objective of this study was to evaluate the effects of β-mannanase (Hemicell® HT 1.5X) on sow and litter performance in a commercial farm. A total of 261 sows averaging 268 kg (± 91 kg) and 3.5 (± 2.3) average parity were randomly allotted to 1 of 2 lactation diets. Dietary treatments included: 1. Corn/soybean meal feed (control) and 2. Control + Hemicell® HT 1.5X (0.25 kg/ton inclusion). Treatments were initiated on d of farrowing and terminated at weaning. All data were analyzed as a randomized complete block design using Proc MIXED in SAS 9.4 (SAS Inst. Inc., Cary, NC). Sow and litter served as the experimental unit, farrowing room as block, and lactation length as a covariate when significant (P ˂ 0.05). Results indicated no significant (P 〉 0.20) differences in sow BW or body condition score (BCS) prefarrowing, postfarrowing, or at weaning. Sows consuming Hemicell® HT 1.5 had significantly (1.43 vs. 1.55; P = 0.03) greater backfat thickness (BF) at weaning and tended (P = 0.10) to lose less weight (-18 vs. -15 kg) than those fed Control. Feed intake, BCS and BF change, and subsequent wean-to-service interval were similar (P 〉 0.41) for sows on both treatments. Litter ADG and wean weight were not different (P 〉 0.18). The results indicate that Hemicell® HT 1.5 improved body reserves at weaning when consumed through the lactation period, suggesting increased energy availability during this period, which could have positive implications on overall lifetime reproductive performance.

    Abstract: Fiber degrading enzymes that contain single or multiple carbohydrolases are commonly used in the US commercial swine industry to reduce pig mortality. The objective of this study was to examine how pig removal from experimental treatments affects growth performance, with or without Rovabio®Advance P10% (RA). The animals on test consisted of 1,260 DNA barrows that were fed from 5.9 to 133 kg. The 4 dietary treatments were: Positive Control (PC), Low Nutrient Density Control (LNDC), PC plus RA (PC+), and LNDC plus RA (LNDC+). The SID AA and NE of the ingredients used were determined using the ingredient profile of the PC formulations and the nutritional modeling calculator for RA. The PC and LNDC+ diets were formulated to have similar NE and SID AA content. In the PC+ diets, RA was added on-top, without reformulation. At the start of the trial, 21 weanling pigs were allotted per pen, with a space allowance of 0.67 m2/pig. For the entire growout, feeding RA reduced the percentage of pigs removed from test (PC 8.3%, LNDC 7.9%, vs PC+ 5.4% and LNDC+ 4.4%; P & lt; 0.03). By day 150, the number of pigs per pen did not differ per treatment (P & gt;0.4) (PC 18.85, LNDC 19.12, PC+ 19.85 and LNDC+ 19.72); however, the respective pig space (m2/pig) was 0.74, 0.73, 0.71 and 0.71. Using the number of pigs/pen as a covariate for ADG, 0-41 d ADG was not significant (P & gt;0.59); however, there was a tendency towards significantly less ADG for pigs on RA between day 107-164 (988g PC, 966g LNDC vs 961g PC+, 961g LNDC+ P = 0.054). Pig removal increases the space per pig/pen over the course of an experiment, thus potentially influencing the ADG and other treatment effects. This effect must be accounted for in any research trial when evaluating the efficacy of any nutritional product.

    Abstract: The objectives of this experiment were to evaluate the effects of alternatives to antibiotic growth promoters (AGP), two group sizes, and their interaction on nursery pig performance to serve as a model for future AGP alternative studies. A 41-d experiment was conducted in a commercial wean-to-finish barn; 1,300 piglets weaned at 21 d of age (weaned 2 or 4 d prior to experiment; 6.14 ± 0.18 kg BW; PIC 1050 sows and multiple sire lines) were blocked by sire, sex, and weaning date, then assigned to eight treatments: four dietary treatments each evaluated across two group sizes. The four dietary treatments were: negative control (NC), positive control (PC; NC + in-feed antibiotics), zinc oxide plus a dietary acidifier (blend of fumaric, citric, lactic, and phosphoric acid) (ZA; NC + ZnO + acid), and a Bacillus-based direct-fed-microbial (DFM) plus resistant potato starch (RS) (DR; NC + DFM + RS). The two group sizes were 31 or 11 pigs/pen; floor space was modified so area/pig was equal between the group sizes (0.42 m2/pig). There were 7 pens/diet with 11 pigs/pen and 8 pens/diet with 31 pigs/pen. Data were analyzed as a randomized complete block design with pen as the experimental unit. Diagnostic assessment of oral fluids, serum, and tissue samples was used to characterize health status. Pigs experienced natural challenges of acute diarrhea and septicemia in week 1 and porcine reproductive and respiratory syndrome virus (PRRSV) in weeks 4–6. There was a significant interaction between diet and group size for ADG (P = 0.012). PC increased ADG in large and small groups (P & lt; 0.05) and ZA increased ADG only in large groups (P & lt; 0.05). Small groups had improved ADG compared to large groups when fed NC or DR diets (P & lt; 0.05). Similarly, PC increased ADFI (P & lt; 0.05). Compared to NC, ZA improved ADFI in large groups only (P & lt; 0.05; diet × group size: P = 0.015). Pigs fed PC had greater G:F than NC (P & lt; 0.05), and small groups had greater G:F than large groups (P & lt; 0.05). There was no effect of ZA or DR on G:F. Pigs fed PC required fewer individual medical treatments than NC and pigs fed ZA were intermediate (P = 0.024). More pigs were removed from large than small groups (P = 0.049), and there was no effect of diet on removals (P & gt; 0.10). In conclusion, careful study design, protocol implementation, sample collection, and recording of important information allowed us to characterize the health status of this group of pigs and determine treatment effects on growth performance and morbidity.

    Abstract: A total of 1260 weaned pigs (PIC 359x1050) from 358 sows were used to determine effects of feeding sows and/or their progeny a proprietary strain of Pichia guilliermondii as a whole-cell inactivated yeast product (WCY; CitriStim, ADM Animal Nutrition, Quincy, IL) on nursery and grow-finish growth performance and carcass characteristics. Sows were fed either a basal gestation/lactation control (CON) diet or CON fortified with 0.1% (0.91 kg/ton) WCY throughout gestation and lactation. Progeny were fed either a CON diet, or CON fortified with 0.15% (1.36 kg/ton) WCY in the nursery period and 0.05% (0.45 kg/ton) WCY in grow-finish. Pigs were allotted (21 pigs/pen, 15 pens/treatment) to 1 of 4 treatments in a 2×2 factorial design. For the nursery period (d0-42 post-weaning), there was no difference in ADG or ADFI (P & gt; 0.05). However, pigs fed WCY in the nursery had lower G:F than pigs fed CON (P = 0.029). Livability of nursery pigs produced from CON fed sows was 92.22% and trended to improve to 94.23% for pigs produced by WCY fed sows (P = 0.157). During the grow-finish period, pigs from sows fed WCY had greater overall ADG (d0-end; 0.89 kg/d vs. 0.92 kg/d), ADFI (2.19 kg/d vs. 2.24 kg/d), and final body weight (BW; 133.97 kg vs. 136.04 kg) compared with pigs from CON fed sows (P & lt; 0.016). A greater hot carcass weight (HCW; 98.51 kg vs. 100.48 kg) and carcass yield percentage was observed for pigs produced from WCY fed sows compared with pigs produced by sows fed CON (P & lt; 0.023). Livability during the grow-finish period was 95.09% for pigs from CON fed sows and trended to increase to 96.92% for pigs produced from WCY fed sows (P = 0.146). In conclusion, feeding sows WCY contributed to improving their progeny’s grow-finish ADG, ADFI, final BW, HCW, and carcass yield percentage. Additionally, a trend for improved combined wean-to-finish livability of 3.84% from sows fed WCY may be meaningful.

    In: Journal of Animal Science, Oxford University Press (OUP), Vol. 99, No. Supplement_3 ( 2021-10-08), p. 115-116
    Abstract: 750 sows (PIC line 42) were used to evaluate the effects of ActiSaf HR+ SC47 live yeast probiotic (AS) on sow and litter performance when fed to sows and their weaned piglets (PIC line 42 x 359). 250 multiparous sows per treatment (average parity 3.6) were fed the control diet without a live yeast probiotic (NC) or a diet with 250 mg/kg AS from breeding through lactation (LY1) or 250 mg/kg AS during gestation and 500 mg/kg AS during lactation. Weaned pigs from these sows were subsequently fed 4-phase nursery diets containing 0 (wNC) or 1 g/kg AS from d 0–10 after weaning followed by 500 mg/kg AS (wLY) from d 10–42 after weaning. This provided a 3x2 nursery trial design. During lactation, number of pigs born; born live varied by treatment (P & lt; 0.05). After weaning, wLY fed pigs had lower BW on d 12, 23; d 0–12 ADG, ADFI, lower d 0–42 ADFI and $/kg gained (P & lt; 0.05). Pigs fed wLY after weaning also tended towards lower d 42 BW and d 0–42 ADG (P & lt; 0.06; Table 1). Conversely, weaned pigs from sows fed LY1 or LY2 had higher ADG and ADFI from d 0–12 and d 0–42 after weaning (P & lt; 0.05) versus pigs from sows fed NC. Pigs from sows fed LY1 or LY2 also had higher BW at d 12, 23, and 42 after weaning than pigs from sows fed NC. Pigs from sows fed LY1 and LY2 tended to have lower nursery $/kg gain (P & lt; 0.06) than pigs from sows fed NC. No significant interactions were observed. Feeding ActiSaf HR+ SC47 live yeast probiotic to gestating and lactating sows improved their weaned pigs’ growth performance and tended to improve piglet cost of production after weaning.

    In: Journal of Animal Science, Oxford University Press (OUP), Vol. 100, No. Supplement_2 ( 2022-04-12), p. 33-33
    Abstract: The objective was to determine the effects of the multi-carbohydrase Rovabio Advance on growth performance, mortality, and morbidity of wean to finish pigs. In the trial, 1,260 DNA weanling barrows were fed from 5.9 kg to 133 kg live weight. Four diets were fed: positive control (PC), low nutrient density control (LNDC), PC with Rovabio Advance (PC+), and LNDC with Rovabio Advance (LNDC+). LNDC compared with PC contained 41 Kcal/kg less NE and 0.012% less SID lysine. Positive control diets contained 1.3% more added fat than LNDC. During each phase, all diets contained equal amounts of wheat middlings and corn DDGS, beginning at 3.75% each and increasing to 15% each. Each pen had 21 pigs each with 15 pens per dietary treatment. Pigs and feed were measured throughout all growth phases, as were the number and weight of dead pigs (mortality) and other pig removals (morbidity). Ten pigs per pen were harvested at 150 d on feed and the balance at 164 d on feed. Pigs fed PC vs LNDC had greater ADG and G:F and final live weight (P & lt; 0.01). Feeding Rovabio reduced pigs removed from test by nearly 40% (8.1 vs 4.9%, (P & lt; 0.03)). Standard deviation within pen of hot carcass weight tended (P & lt; 0.22) to be reduced by feeding Rovabio Advance and was reduced (P & lt; 0.03) by LNDC vs PC. Pig value per unit carcass weight was improved by Rovabio Advance (P & lt; 0.14) and by LNDC (P & lt; 0.01). In conclusion, feeding Rovabio Advance from weaning (5.9 kg) to finish (133 kg) decreases pig morbidity.
