We evaluated the effects of a plant extracts mixture (XT) standardized in 5% (wt/wt) carvacrol, 3% cinnamaldehyde, and 2% capsicum oleoresin (oregano, cinnamon Mexican pepper), alone or combination with formic acid (FA), on productive performance intestinal ecosystem early-weaned pig. Pigs weaned at 20 ± 1 d age (n = 216) were allocated 24 pens fed standard medicated prestarter diet for 12 d. Twelve days after weaning, stress management system based social dietary factors was applied to...
We evaluated the effects of a 6% spray-dried porcine plasma (SDPP) and plant extracts mixture (XT; 5% carvacrol, 3% cinnamaldehyde, 2% capsicum oleoresin) on productive performance, intestinal morphology, leukocyte cell subsets early-weaned pigs compared with control group. Morphometry jejunum, ileum, colon, immune analysis blood, ileocolic lymph node (LN), ileal Peyer's patches were done in 24 weaned (20 +/- 2 d) at 19 or 21 d postweaning. Although SDPP XT treatments did not increase ADG...
We evaluated the effects of 3 additives, sodium butyrate (AC), avilamycin (AB), and a combination plant extracts (XT), on productive performance intestinal environment early-weaned pig. The XT was standardized mixture with 5% (wt/wt) carvacrol (from Origanum spp.), 3% cinnamaldehyde Cinnamonum 2% capsicum oleoresin Capsicum annum). Pigs (n = 32) weaned at 18 to 22 d age an initial BW 6.0 +/- 0.10 kg were allocated 8 pens that, in turn, 4 treatments. treatments included basal diet (CT) or...
An experiment was designed to evaluate the effects of 3 different additives on gastrointestinal microbiota early-weaned pigs. Early-weaned (18 22 d; n = 32) pigs (6.0 +/- 0.10 kg BW) from 8 litters were randomly distributed into pens. Each pen assigned 1 4 dietary treatments: a prestarter or control diet, diet with 0.04% avilamycin (AB), 0.3% sodium butyrate, 0.03% plant extract mixture (XT; standardized 5% (wt/wt) carvacrol extracted Origanum spp., 3% cinnamaldehyde Cinnamonum and 2%...
Using dietary fibre to control childhood diarrhoea has rarely been discussed. However, is being proposed prevent in piglets. The present study aimed the effects of introducing post-weaning piglet diet and its particle size on intestinal ecosystem before after an experimental infection with Escherichia coli . A total thirty-six piglets were assigned four diets: a negative (NC) diet, same 4 % wheat bran coarse (WBc) or finely milled (WBF) positive (PC) antibiotic. On day 9, animals challenged...
A study was conducted to evaluate the interaction among 3 levels of Ca and 4 nonphytate phosphorus (NPP) on broiler performance, bone ash, whole-body fractional retention P. Ross male broiler-chicks (n = 420) were sorted by BW at d 1 posthatch assigned 5 cages/diet with 7 birds/cage. Twelve diets arranged in a × factorial (at 0.5, 0.7, or 0.9%) NPP 0.25, 0.31, 0.38, 0.45%) high dose phytase (1,150 U/kg) all diets. On 14, chickens euthanized right tibia collected from birds/replicate; rest...
Objectives Our objective was to perform the first multicentric study in Spain evaluate prevalence of feline herpesvirus-1 (FHV-1), calicivirus (FCV), Chlamydophila felis and Mycoplasma cats with upper respiratory tract disease (URTD), conjunctivitis and/or gingivostomatitis (GS) compared control cats; risk factors for these clinical conditions. Methods Conjunctival oropharyngeal swabs were collected a questionnaire regarding signalment, lifestyle, vaccination history signs obtained each cat....
Gliomas in dogs remain poorly understood.
The aim of the study was to develop a vitality scoring method, based on piglet behavior and relate it growth survival. From 21 sows (Sus scrofa), 287 piglets were used. After farrowing (d 0), weighed tested for 4 behavioral parameters in circular enclosure (55 cm diam.): movement capacity (M), udder stimulation (U), number completed circles around (NCC), screaming (Sc). Piglets again d 1, 2, 3, 17. Piglet rectal temperature (RT) recorded 0, 3. Farrowing information sow also recorded....
The inclusion of fibre has been studied as an alternative to antimicrobials in weaning pig diets, while ZnO is used effective method prevent post-weaning diarrhoea. However, it not investigated what extent these two strategies interact with each other. present study was designed evaluate the effects including wheat bran (WB) and alone or combined diet early-weaning pigs on productive performance microbial activity gastrointestinal tract (trial 1). A total sixty-four piglets were distributed...
Incorporating indicators for pig health and welfare at meat inspection could reduce the need on-farm assessments. Skin tail lesions are important in pigs with good potential to record during possibly function as iceberg of on farm welfare. The aim this study was validate use these carcass assessment farm. Thirty-one farrow-to-finish farms (∼12% Irish herds) were assessed using an adapted version Welfare Quality protocol by inspecting 6 randomly selected pens first weaner (4 8 wk), second (8...
The aim of this study was to assess the relationship between tail lesions, cold carcass weight and viscera condemnations in an Irish abattoir. following data were collected at evisceration point from every 3rd pig slaughtered over 7 days: farm identification, sex, lesion score, inspection outcome weight. Tail lesions scored according a 5 scale. Disease responsible for lung (pleurisy, pneumonia abscess), heart (pericarditis) liver (ascariasis) condemnation recorded based on decision...
This study aimed to 1) identify cross-fostering (CF) practices employed on a commercial farm; 2) characterise CF pigs according litter of origin traits and 3) investigate the implications pig mortality, performance welfare. was an observational whereby were managed normal farming practice. Pigs (n=1,016) born within 1 week classified as non-CF (NCF); during first (CFW1) second or third (CFW2+) weeks lactation. individually weighed inspected for presence tail (TL), ear (EL) body lesions (BL)...
Abstract Background Streptococcus suis ( S. ) is a Gram-positive bacteria that infects pigs causing meningitis, arthritis, pneumonia, or endocarditis. This increases the mortality in pig farms deriving severe economic losses. The use of saliva as diagnostic fluid has various advantages compared to blood, especially pigs. In this study, it was hypothesized could reflect changes different biomarkers related stress, inflammation, redox status, and muscle damage with infection these be severity...
The prophylactic use of antimicrobials and zinc oxide (ZnO) in pig production was prohibited by the European Union 2022 due to potential associations between antimicrobial heavy metal usage with resistance (AMR) concerns regarding environmental pollution. However, effects their on bacterial AMR profiles commercial farms are still not fully understood previous studies examining effect ZnO have reported contrasting findings. objective this study examine farms. Faecal samples were taken 10...
Antimicrobial use (AMU) data are essential to monitor the impact of AMU reduction strategies in animal health. The technology and herd recording software record will be vital scale collation these future. aim this study was determine barriers facilitators Irish dairy farmers their using a sharing data. Thirty-three involved on monitoring were asked over 12-mo period. At end period, 10 selected take part semi-structured interviews exploring opinions AMU, software, Interviews transcribed...
Bacteriophage research has experienced a renaissance in recent years, owing to their therapeutic potential and versatility biotechnology, particularly combating antibiotic resistant-bacteria along the farm-to-fork continuum. However, certain pathogens remain underexplored as targets for phage therapy, including zoonotic pathogen Streptococcus suis which causes infections pigs humans. Despite global efforts, genome of only one infective S. been described. Here, we report isolation two phages...
Chronic coughing is a common complaint in small animal medicine and it has an extensive differential diagnosis with very different treatment prognosis. Coughing considered chronic when lasts at least 8 weeks. This retrospective study aimed to describe the most causes of population dogs that presented referral hospital England between January 2012 December 2021. In addition, we evaluate if association signalment, weight, characteristics, and/or concomitant clinical signs could be identified....
