[Ab] Resumo:Bovine foot rot (BFR) is an infectious disease of the interdigital skin and subcutaneous tissues of beef and dairy cattle that occurs under a variety of management and environmental settings. The anaerobic, gram-negative bacteria Fusobacterium necrophorum, Porphyromonas levii, and Prevotella intermedia are commonly isolated from lesions. A multitude of host, agent, and environmental factors contribute to the development of BFR. Initiation of systemic antimicrobial therapy early in the course of disease commonly leads to resolution. Delays in treatment may result in extension of infection into deeper bone, synovial structures, or ligamentous structures, and the prognosis for recovery is reduced.

[Ab] Resumo:INTRODUCTION: Two flocks of ewes with lambs were compared for differences in performance. One group was permanently infected with footrot, the other one served as healthy control. They were kept in the same barn but in different bays during lambing and on pasture during the summer. Biweekly all animals were weighed and in the affected group all feet were scored for severity of footrot and if necessary the claws were treated. Furthermore the body condition was scored 4 times in the ewes. The lambs were slaughtered with 43 kg. At that time age and carcass quality were used as parameters. In 20 lambs of each group the lying behaviour was measured using a datalogger during 5 consecutive days. The results revealed significant differences in the performance of ewes and lambs between the two groups. The overall duration of fattening was 31.8 days longer in affected animals. Most importantly, even mild footrot led to significantly impaired growth of the lambs and an altered lying behaviour compared to the healthy controls. The lying periods were more frequent but of shorter duration in affected lambs.

[Ab] Resumo:is a fastidious, strictly anaerobic bacterium, an obligate parasite of the ruminant hoof, and the essential causative agent of virulent ovine footrot. The clinical disease results from a complex interplay between the pathogen, the environment, and the host. Sheep flocks diagnosed with virulent but not benign footrot in Australia may be quarantined and required to undergo a compulsory eradication program, with costs met by the farmer. Virulence of at least partially depends on the elaboration of a protease encoded by and manifests as elastase activity. Laboratory virulence tests are used to assist diagnosis because clinical differentiation of virulent and benign footrot can be challenging during the early stages of disease or when the disease is not fully expressed due to unfavorable pasture conditions. Using samples collected from foot lesions from 960 sheep from 40 flocks in four different geographic regions, we evaluated the analytical characteristics of qPCR tests for the protease gene alleles and , and compared these with results from phenotypic protease (elastase and gelatin gel) tests. There was a low level of agreement between clinical diagnosis and quantitative PCR (qPCR) test outcomes at both the flock and sample levels and poor agreement between qPCR test outcomes and the results of phenotypic virulence tests. The diagnostic specificity of the qPCR test was low at both the flock and individual swab levels (31.3% and 18.8%, respectively). By contrast, agreement between the elastase test and clinical diagnosis was high at both the flock level (diagnostic sensitivity [DSe], 100%; diagnostic specificity [DSp], 78.6%) and the isolate level (DSe, 69.5%; DSp, 80.5%).

[Ti] Título:Cost-benefit analysis of management practices for ewes lame with footrot.

[Ab] Resumo:The aim of this study was to investigate the cost-benefit of different strategies to treat and control ovine footrot. In November 2006, 162 sheep farmers in England responded to a survey on prevalence and management of lameness. The costs of lameness per ewe per year (PEPY) were calculated for 116 flocks. Linear regression was used to model the overall cost of lameness PEPY by management method. Associations between farmer satisfaction and time and money spent managing lameness were investigated. The median prevalence of lameness was 5% (inter-quartile range, IQR, 4-10%). The overall cost of lameness PEPY in flocks with ≥10% lameness was UK £6.35 versus £3.90 for flocks with <5% lameness. Parenteral antibiotic treatment was associated with a significantly lower overall cost of lameness by £0.79 PEPY. Routine foot trimming and foot bathing were associated with significantly higher overall costs of lameness PEPY of £2.96 and £0.90, respectively. Farmers satisfied with time managing lameness spent significantly less time (1.46 h PEPY) than unsatisfied farmers (1.90 h PEPY). Farmers satisfied with money spent managing lameness had significantly lower treatment (£2.94 PEPY) and overall (£5.00 PEPY) costs than dissatisfied farmers (£5.50 and £7.60 PEPY, respectively). If the farmers in this study adopted best practice of parenteral antibiotic treatment with no routine foot trimming, and minimised foot bathing to treatment/prevention of interdigital dermatitis, the financial benefits would be approximately £4.65 PEPY. If these costs are similar on other farms the management changes would lead to significant economic benefits for the sheep industry.

[Ti] Título:Associations between sheep farmer attitudes, beliefs, emotions and personality, and their barriers to uptake of best practice: The example of footrot.

[Ab] Resumo:There is interest in understanding how farmers' behaviour influences their management of livestock. We extend the theory of planned behaviour with farmers attitudes, beliefs, emotions and personality to investigate how these are associated with management of livestock disease using the example of footrot (FR) in sheep. In May 2013 a one-year retrospective questionnaire was sent to 4000 sheep farmers in England, requesting data on lameness prevalence, management of footrot, farm/flock descriptors, and farmer-orientated themes: barriers to treating footrot, opinions and knowledge of footrot, relating to other people and personality. Principal component analysis (PCA) was used to make composite variables from explanatory variables and latent class (LC) analysis was used to subgroup farmers, based on nine managements of FR. Associations between LC and composite variables were investigated using multinomial logistic regression. Negative binomial regression was used to investigate associations between the proportion of lame sheep and composite and personality variables. The useable response rate was 32% and 97% of farmers reported having lame sheep; the geometric mean prevalence of lameness (GMPL) was 3.7% (95% CI 3.51%-3.86%). Participants grouped into three latent classes; LC1 (best practice-treat FR within 3days of sheep becoming lame; use injectable and topical antibiotics; avoid foot trimming), 11% farmers), LC2 (slow to act, 57%) and LC3 (slow to act, delayed culling, 32%), with GMPL 2.95%, 3.60% and 4.10% respectively. Farmers who reported the production cycle as a barrier to treating sheep with FR were more likely to be in LC2 (RRR 1.36) than LC1. Negative emotions towards FR were associated with higher risk of being in LC2 (RRR 1.39) than LC1. Knowledge of preventing FR spread was associated with a lower risk of being in LC2 (RRR 0.46) or LC3 (RRR 0.34) than LC1. Knowledge about FR transmission was associated with a lower risk of being in LC3 (RRR 0.64) than LC1. An increased risk of lameness was associated with the production cycle being a barrier to treating sheep with FR (IRR 1.13), negative emotions towards FR (IRR 1.13) and feelings of hopelessness towards FR (IRR 1.20). Conscientiousness (IRR 0.95) and understanding the importance of active control of lameness (IRR 0.76) were associated with reduced risk of lameness. We conclude that emotions and personality are associated with differences in farmer management of FR and prevalence of lameness. Further understanding how personality and emotions influence change in behaviour is key to increasing uptake of new information.

[Ti] Título:Inter-observer agreement for clinical examinations of foot lesions of sheep.

[Ab] Resumo:In sheep, the diagnosis of foot lesions is routinely based on physical examination of the hoof. Correct diagnosis is important for the effective treatment, prevention and control of both infectious and non-infectious causes of lameness. Therefore, the aim of this study was to evaluate the level of inter-observer agreement for clinical examination of ovine foot lesions. Eight observers of varying experience, training and occupation performed foot examinations on a total of 1158 sheep from 38 farms across North England and Wales. On each farm, a group of two to four observers independently examined a sample of 24 to 30 sheep to diagnose the presence or absence of specific foot lesions including white line lesions (WL), contagious ovine digital dermatitis (CODD), footrot (FR), inter-digital dermatitis (ID) and toe granuloma (TG). The inter-observer agreement of foot lesion assessments was examined using Fleiss kappa (κ), and Cohen's κ examined the paired agreement between the test standard observer (TSO) and each observer. Scoring differences with the TSO were examined as the percentage of scoring errors and assessed for evidence of systematic scoring bias. With the exception of WL (maximum error rate 33.3%), few scoring differences with the TSO occurred (maximum error rate 3.3%). This suggests that observers can achieve good levels of reliability when diagnosing most of the commonly observed foot conditions associated with lameness in sheep.
