Balanced bacterial communities within the gastrointestinal (GI) tract of animals are a key component gut health, resulting in optimal performance and prevention disease. The purpose this study was to characterize commercial pig's baseline microbiome over time across anatomical site. Several sites (duodenum/jejunum, ileum, cecum, colon) were examined multiple ages (days 0, 10, 21, 33, 62, 84, market) for structure using 16S rRNA V4 region sequencing with Illumina MiSeq. General trends...

Litter performance and progeny health status may be decreased in derived from primiparous sows but improve with increasing parity. The objective was to evaluate litter performance, the production passive transfer of Ig, fecal microbial populations first parity (P1) compared fourth (P4) dams. recorded for P1 (n = 19) P4 24) dams including number pigs/litter (total born, born live, stillbirths, mummified fetuses, prewean mortality, pigs weaned) average piglet BW at birth (d 0), d 7, 14,...

Spray-dried porcine plasma (SDPP) has been considered as an alternative for in-feed antibiotics to improve pig growth performance; however, the effect of SDPP on gut microbiota is unknown. The objective this study was evaluate effects feeding fecal microbial communities nursery pigs. Ninety-six weaned pigs were assigned 16 pens, which allotted two dietary treatments, including control or + (5% and 2.5% inclusion in phase 1 2, respectively) diet. Fecal samples collected at d 0, 7, 14, 21, 28....

This work evaluated the National Research Council (NRC) dairy model (2001) predictions of rumen undegradable (RUP) and degradable (RDP) protein compared with measured postruminal non-ammonia, nonmicrobial (NANMN) microbial N flows. Models were using root mean squared prediction error (RMSPE) as a percent observed mean, slope biases percentages (MSPE), concordance correlation coefficient (CCC). The NRC over-estimated NANMN by 18% under-estimated 14%. Both responses had large (19% 20% MSPE,...

Two experiments were conducted to evaluate the effects of spray-dried porcine plasma (SDPP) on growth performance, immunity, antioxidant capacity, and gut morphology nursery pigs. In Exp. 1, 96 weaned pigs (Nebraska female × Danbred sire; 20 ± 1 d age; initial BW = 6.06 0.02 kg) assigned 16 pens randomly allotted control (CTL; no SDPP) or CTL + SDPP treatment in 2 phases (phase 1: 0 14, 5% SDPP; phase 2: 14 28, 2.5% SDPP). Blood samples collected weekly thereafter quantify IgG, IgA, total...

Two experiments were conducted to investigate the effects of collection method and diet type on digestibility coefficients. In Exp. 1, 24 barrows fed either a corn-soybean meal (CSBM) or CSBM with 20% dried distillers' grains solubles (CSBM-DDGS). 2, basal determination (DDGS) studied using barrows. The 4 diets used in 2 were: (basal 1) , barley-canola (BCM; 2), 80% 1 DDGS (CSBM-DDGS), (BCM-DDGS). both experiments, feces collected time-based (DY) "marker-to-marker" (MM). Diets contained 0.5%...

An experiment was conducted to evaluate the effects of dietary lactose alone or in combination with a yeast-dried milk product (50% dried near-dated and 50% yeast) on growth performance, fecal microbiota, immune status nursery pigs (Sus scrofa). A total 108 (age, 20 ± 1 d; initial BW, 6.07 0.03 kg) were randomly allotted 18 pens (6 pigs/pen; 6 pens/treatment). Dietary treatments were: 1) control, 2) control + lactose, 3) 5% milk. Except for diet, diets Phase (wk 2), 2 3 4), 5) contained 20,...

Two experiments were conducted to evaluate effects of corn distillers dried grains with solubles (DDGS) on growth performance and health status weanling pigs. Experiment 1 evaluated increasing concentrations DDGS Dietary treatments included 1) control (CTL), 2) 0% (0% in phase 2 30% 3), 3) 5% (5% 4) (phases 3). Overall, pigs fed during phases 3 had decreased (22.1 vs. 25.1 24.0 kg; P = 0.003) BW compared CTL that only received 3. In addition, 5 or (422.7 390.0 468.2 g; ADG However, similar...

Abstract The objective of the experiment was to investigate effects prebiotics in nursery pigs on growth performance and immune biomarkers. Sixty-four weaned (31 ± 1 d; BW 8 0.1 kg) mixed gender were housed (4 pigs/pen) an environmentally controlled with ad libitum access feed water over a 35-d study. Pigs randomly assigned one four treatments: control (53% corn, 32% SBM, 7% fishmeal, 8% others), + 2.5% GroBiotic-S (GS), 0.05% chicory (CL), or 0.5% (CH). Feeders weighed weekly. On day 21,...

Millions of feed composition records generated annually by testing laboratories are valuable assets that can be used to benefit the animal nutrition community. However, it is challenging manage, handle, and process data originate from multiple sources, lack standardized names, contain outliers. Efficient methods consolidate screen such needed develop databases with accurate means standard deviations (SD). Considering interest science community in management importance tables for industry,...

Uterine torsion are extremely rare in pregnancy as few cases have been reported. Torsion of the pregnant uterus is defined rotation more than 45 degrees around long axis uterus. It has referred as, once-in-a-lifetime diagnosis by obstetricians and gynecologists. This paper reports a case uterine velamentous cord insertion from our obstetrical practice, along with review reported cases. The 30-year-old patient (G2P1) at 38 weeks' gestation singleton pregnancy, was admitted to Obstetrical Unit...

The objective of this study was to define changes in the intestinal metabolome and microbiome associated with growth performance weaned pigs fed subtherapeutic concentrations antibiotics. Three experiments same antibiotic treatments were conducted on research farm but two different facilities (nursery wean-finish) using at 20-days age from source herd genotype, diets formulated without antibiotics (NC) or 0.01% chlortetracycline sulfamethazine (AB). Pigs weighed feed disappearance determined...
