ABSTRACT Dietary doses of 2,500 ppm ZnO-Zn reduced bacterial activity (ATP accumulation) in digesta from the gastrointestinal tracts newly weaned piglets compared to that animals receiving 100 ZnO-Zn. The amounts lactic acid bacteria (MRS counts) and lactobacilli (Rogosa were reduced, whereas coliforms (MacConkey enterococci (Slanetz counts, red colonies) more numerous high ZnO dose. Based on 16S rRNA gene sequencing, colonies MRS dominated by three phylotypes, tentatively identified as...
Abstract Digestive disorders and impaired performance are common problems among weanling piglets. The purpose of the present study was to examine effect on health feeding different levels zinc (as oxide) for one, two or three weeks after weaning piglets weaned at 28 days age. A supplement 2500 ppm reduced incidence severity non-specific post-weaning diarrhoea by up 50%. daily gain, but not feed intake efficiency, significantly influenced dietary level. Piglets fed showed best performance....
The current study was conducted to investigate the effects of high dietary concentrations Zn as zinc oxide and Cu copper sulfate on activity digestive enzymes in pancreas intestinal mucosa, morphology, mucin histochemistry pigs after weaning. Thirty-two were weaned at 4 wk age. fed standard weaning diets supplemented with (100 or 2,500 ppm) (0 175 a 2 × factorial arrangement treatments for 14-d period. In pancreatic tissue, amylase, carboxypeptidase A, chymotrypsin, trypsin, lipase increased...
Lameness and impaired walking ability in rapidly growing meat-type broiler chickens are major welfare issues that cause economic losses. This study analyzed the prevalence of its associations with production data, abattoir registrations, postmortem tibia measurements Norwegian chickens. Gait score (GS) was used to assess 59 different commercial flocks (Ross 308) close slaughter d, 5,900 broilers total, 3 geographical regions. In each flock, 100 arbitrary were gait scored 10 random culled...
Providing environmental enrichment for broilers is a potential strategy to increase welfare, activity, and health. The aim of this study was evaluate the effect on health leg bone characteristics broilers. One control 8 types were included: 2 distances between food water (7 3.5 m), roughage, vertical panels, straw bales, platforms (30 5 cm), lowered stocking density (34 kg/m2). Birds kept according conventional Danish guidelines. included 58 pens with approximately 500 birds each. On day 35...

Abstract Phosphorus deficiency is known to result in depressed growth and bone abnormalities pigs ( Sus scrofa ). As such, practical pig feeding recommendations have over the years aimed at ensuring that would not suffer from P deficiency. This means a large safety margin has normally been included into order compensate for variation digestibility feedstuffs feed phosphates. However, increasing attention devoted utilization excretion of production last decade. Because continuous accumulation...
In production systems, piglets usually fast for a period after weaning, thereby increasing the risk of diarrhea and reduction in growth. The low level eating may relate to insufficient drinking activity, as solid feed intake must be accompanied by water intake. Mixing newly weaned is well-known stressor common procedure pig production. effect mixing on temporal development activity has not been elucidated. High concentrations zinc (Zn) improve health performance but underlying mechanisms are...
Supplementation of benzoic acid to pig diets reduces the pH urine and may thereby affect emissions ammonia other gases from slurry, including sulfur‐containing compounds that are expected play a role in odor emission. Over period 112 d, we investigated hydrogen sulfide (H 2 S), methanethiol (MT), dimethyl (DMS), disulfide (DMDS), trisulfide (DMTS), as well methane stored slurry. The slurry was derived feeding experiment with four factorial design 2% (w/w) 1% methionine supplementation...
Dietary benzoic acid (BA) supplementation causes a pronounced reduction in urinary pH but only small changes blood pH. The present study aimed to investigate the portal absorption profile, hepatic metabolism of BA, and renal excretion hippuric (HA) underlying relatively impact BA on systemic acid-base status. Eight growing pigs (BW = 63 ± 1 kg at sampling) fitted with permanent indwelling catheters abdominal aorta, vein, mesenteric vein were allocated 4 sampling blocks randomly assigned...
The aims of this study were to investigate 1) the effect high dietary fiber (DF; 19.3% 21.7%) supplemented late gestating sows on mammary uptake and metabolism energy substrates as well colostrum production 2) ontogeny colostral fat lactose synthesis using carbon balance, protein IgG a biomarker. Sows fed either control diet (CON) consisting standard gestation (14.6% DF) until day 108 transition (16.8% from 109 farrowing or DF treatment where part daily ration was replaced with supplement...
One hundred and eighty individually housed piglets with an initial body weight of 7.63 ± 0.98 kg (at 28 days age) were fed a diet containing either 153, 493, 1022, 1601, 2052 or 2407 mg zinc/kg (added Zn as zinc oxide; ZnO) from day 0-21 post weaning to determine the optimal level for weaned piglets. Body weight, feed intake faecal scores recorded, blood samples collected. Dietary content quadratically affected both gain in first two weeks, approximately 1400 Zn/kg 400 mg/day levels. The...
The objective was to define the Val requirement for weaned piglets in context of reducing dietary protein content. A dose–response experiment conducted estimate standardized ileal digestible (SID) Lys ratio required support optimum growth post-weaned piglets. In this study, 96 pigs weighing 8 kg were allotted one six treatments (16 each treatment) and housed individually. Diets formulated provide 0.58, 0.62, 0.66, 0.70, 0.74 0.78 SID : by adding graded levels crystallinel-Val 0.58 diet....
