A consensus of expert opinion was used to provide both face and consensual validity a list potential indicators sheep welfare. This approach as first step in the identification valid welfare for sheep. The methodology National Institute Health, using pre-meeting consultation focus group discussions, ascertain panel experts. Farm Animal Welfare Council's five freedoms were framework organise current on-farm issues also criterion identify As result, experts identified 193 lambs managed on...
Antimicrobial stewardship guidelines (ASGs) represent an important tool to help veterinarians optimize their antimicrobial use with the objective of decreasing resistance. The aim this study was map and qualitatively assess ASGs for in cats dogs Europe. Country representatives European Network Optimization Veterinary Treatment (ENOVAT) were asked identify published countries. All collated updated since January 2010 containing recommendations on therapy at least three conditions affecting...
Footrot and contagious ovine digital dermatitis (CODD) are common causes of foot disease sheep in the UK. The study reported here is a split flock randomised treatment trial undertaken on group 748 fattening lambs UK farm affected by CODD footrot. were randomly assigned to one two protocols. In protocol A, all given doses footrot vaccine (Footvax, MSD), plus targeted antibiotic therapy (long-acting amoxicillin, Betamox LA, Norbrook Pharmaceuticals) with lesions likely be associated bacterial...
This study tested the reliability of a Qualitative Behavioural Assessment (QBA) protocol developed for Norwegian Sheep House (FåreBygg) project. The aim was to verify whether QBA scores were consistent between different observers, i.e., inter-observer reliability, and scorings same observers on time points, intra-observer reliability. Six trained including two veterinary students, animal welfare inspectors sheep farmers observed in 16 videos, independently scored 14 pre-defined behavioural...
The present study is a randomised split-flock treatment trial, which compared the effect of foot bathing in 1 per cent solution chlortetracycline alone with protocol that added single injection long-acting amoxicillin. Overall, prevalence contagious ovine digital dermatitis examined flock was 22 cent, while 45.7 affected sheep had infections two or more feet. Parenteral antibiotic increased odds recovery by 3.8 times (95 confidence interval 1.05 to 14.0) (P=0.008). Moreover, amoxicillin may...
A scientific literature review and consensus of expert opinion used the welfare definitions provided by Farm Animal Welfare Council (FAWC) Five Freedoms as framework for selecting a set animal-based indicators that were sensitive to current on-farm issues young lambs (aged ⩽6 weeks). Ten assessed observation – demeanour, response stimulation, shivering, standing ability, posture, abdominal fill, body condition, lameness, eye condition salivation tested part objective developing valid,...
Sixteen animal-based indicators of sheep welfare, previously selected by a stakeholder panel, and based on the Farm Animal Welfare Council (FAWC) Five Freedoms, were assessed in terms level inter-observer agreement achieved during on-farm testing. Eight observers independently tested 16 1158 from 38 farms England Wales. Overall was evaluated Fleiss’s kappa (κ), pair-wise each observer compared to ‘test standard’ (TSO). Inter-observer assessments welfare indicators; dental abnormality,...
Abstract Supernumerary nipples or teats (polythelia) are congenital accessory structures that may develop at any location along the milk line and have been implicated in pathogenesis of mastitis. We describe anatomy histology 27 spontaneously occurring supernumerary from 16 sheep, delineating two groups – simple anatomically complex according to complexity microenvironment. Anatomically exhibited significantly increased length barrel diameter compared with teats. A teat canal and/or cistern...
Background : Ovine pregnancy toxaemia (OPT) is a metabolic disorder of ewes in late pregnancy. Cases are typically seen carrying multiple fetuses, hence the alternative name ‘twin lamb disease’. The disease has been well known for many years. Despite this, toll inflicted by remains considerable, due both to poor prognosis clinically affected animals, even with appropriate treatment, and impact provoking factors under‐nutrition concomitant on ewe morbidity, survival flock productivity. OPT an...
Fell pony foals are affected by a congenital fatal immunodeficiency that commonly leads to anaemia and lymphopenia. Previous work has shown the foals' circulating subpopulations of CD4 CD8 T lymphocytes unaffected. In this study it was mean population B in 10 less than per cent normal foals.
This is the first in a series of three articles that examine opportunities for veterinary practitioners and livestock advisers to engage sheep farmers proactive health production planning. It focuses on use on‐farm records identify specific flock health, welfare issues setting farm‐specific targets action plans. Subsequent will look at nutrition, ways which financial performance indicators can be used demonstrate economic future benefit
Background To monitor the prevalence of antimicrobial resistance (AMR), methods for interpretation susceptibility phenotypes bacteria are needed. Reference limits to declare generally based on or dominated by data from human bacterial isolates and may not reflect clinical relevance wild type (WT) populations in livestock other hosts. Methods We compared observed AMR using standard bespoke interpretations breakpoints epidemiological cut-offs (ECOFF) gram positive (Staphylococcus aureus)...
Flock nutrition is a vital aspect of good animal health and production. This article, the second in series three examining opportunities for veterinary practitioners livestock advisers to engage more sheep farmers active planning, discusses practical ways assessing flock nutrition, with particular reference pregnant ewes.
Outbreaks of infectious arthritis in young lambs are a growing concern for the Norwegian sheep industry. In other countries, Streptococcus dysgalactiae subspecies (SDSD) is frequent cause such outbreaks. The objectives this study were to investigate causes outbreaks infections flocks, and describe sources, colonization patterns genetic diversity SDSD affected healthy flocks. Almost 2000 samples from joints, animal body sites indoor environment analysed by qPCR culturing SDSD, which was...
This article aims to review the current literature base, and share findings of clinical experience from British Norwegian first opinion referral work in ovine Caesarean sections. It is not intended replace existing excellent medicine surgery texts describing (such as Scott, 2015 or Hendriksen Baird 2013) but supplement these with additional information provide an updated review. We hope this particularly useful for those approaching their section practice, may stimulate further interest...
The outbreak of a previously unknown and new disease in the United Kingdom, known as ‘Schmallenberg disease’, associated with abortions, stillbirths fetal deformities naïve ewes, was reported for first time South West England during 2012/13 early lambing season. Epidemiological studies confirmed that Schmallenberg virus (SBV) had severe negative impact upon animal welfare productivity affected flocks. By contrast, there specific lack research on SBV sheep farmer well-being. This study aimed...
A condition resembling acquired immunodeficiency with anemia has been described in British Fell pony foals. The pathogenesis is unknown. present study involved 322 foals of which 164 were breed and 12 affected. Discriminant multiple regression analyses used to test the results all clinical pathology parameters from these for statistical association (1) origin (2) presence disease. Only hematocrit associated significantly However, significant associations found origin, including serum albumin...
Abstract Background Outbreaks of infectious arthritis in young lambs associated with Streptococcus dysgalactiae subspecies (SDSD) lead to reduced animal welfare, increased use antibiotics and economic losses for sheep farmers. Understanding risk factors is essential when developing strategies prevent such outbreaks. This questionnaire-based cross-sectional study classified flocks respondents as cases or controls. Flock-level outbreaks were assessed using a multivariable logistic regression...
