Identifying physiological measures of lifetime welfare status in pigs: exploring the usefulness of haptoglobin, C-reactive protein and hair cortisol sampled at the time of slaughter

Background: Physiological measures indicative of the welfare status of animals during rearing could form part of an abattoir-based animal health and welfare assessment tool. A total of 66 pigs were used in this study, the aim of which was to assess how serum concentrations of haptoglobin (Hp) and C-reactive protein (CRP) (assessed in 51 pigs), and hair concentrations of cortisol (assessed in 65 pigs), measured at or close to slaughter, reflected welfare-related indicators recorded from the animal during its lifetime. These indicators were recorded at intervals between 7 and 21 weeks of age and included assigning scores for levels of tail and skin lesions, recording the presence or absence of certain health issues, and conducting qualitative behavioural assessments (QBA). Results: Pigs recorded as having tail lesions during their lifetime had higher hair cortisol levels than those with no tail lesions (tail lesions: 47.87 ± 3.34 pg/mg, no tail lesions: 42.20 ± 3.29 pg/mg, P = 0.023), and pigs recorded as having moderate or severe tail lesions had higher Hp levels than those with no or mild tail lesions (moderate/severe: 1.711 mg/ml ± 0.74, none/mild: 0.731 mg/ml ±0.10, P = 0.010). Pigs recorded as being lame during their lifetime tended to have higher hair cortisol levels than non-lame pigs (lame: 52.72 pg/mg ± 3.83, not lame: 43.07 pg/mg ± 2.69, P = 0.062). QBA scores were not associated with any of the physiological measures (P > 0.05). Receiver Operator Curve (ROC) analysis was also carried out to get a better understanding of the usefulness of the physiological measures in discriminating animals that had had welfare-related issues recorded during their lifetime from those that had not. Hair cortisol was determined as having ‘moderate’ accuracy in discriminating pigs that were tail bitten on-farm from unbitten pigs (AUC: 0.748) while Hp and CRP were determined to have no meaningful discriminatory ability (AUC < 0.600). Conclusion: This research should be repeated on a larger scale, but the results suggest that hair cortisol measured at slaughter could provide insight into the welfare status of pigs during their lifetime. Hp may be a useful indicator of tail lesions in pigs. However, further research utilising a greater proportion of severely bitten pigs is required before conclusions can be drawn

Pathological findings in spontaneously dead and euthanized sows - a descriptive study

Background:A high rate of euthanized and spontaneously dead sows causes production losses and likely indicatesunderlying welfare problems. Identification of predisposing factors to on-farm deaths requires a thoroughunderstanding of the causes. Post-mortem examination is needed for a proper diagnosis. The aims of thisdescriptive study were to determine causes of spontaneous deaths and euthanasia in sows in a conveniencesample of Finnish herds and to describe pathological findings in the locomotor system and in teeth and gums.Results:This study described post-mortem findings in 65 sows found dead or euthanized on 15 farms. All but oneof the sows presented with two or more pathological findings. The majority of primary pathologic-anatomicdiagnoses (PAD-1) were inflammatory. The most prevalent diagnoses were arthritis and peritonitis (9% of sowseach). The locomotor system was the body part most commonly affected by lesions. Findings in the locomotorsystem unassociated with death were present in 85% of the animals, additionally 29% of PAD-1 s concerned thelocomotor system. The prevalence for both degenerative joint disease and tooth wear was 71%. Farmers had notedclinical signs within 30 days of death in every euthanized sow and in half of the spontaneously dead ones. Thefarmer’s impression of the cause of death agreed at least partly with the PAD-1 in 44% of the cases.Conclusion:Multiple pathologies were the norm in the present animals. This may indicate an extended course ofillness and therefore also an unnecessary delay in medical treatment or euthanasia. The prevalence and clinicalrelevance of the most common disorders, including degenerative joint disease and tooth wear, need to beelucidated.Peer reviewe

Efficacy and safety of parecoxib in the treatment of acute renal colic: a randomized clinical trial

PURPOSE: Although nonselective nonsteroidal anti-inflammatory drugs (nsNSAIDs) and opioids are effective treatments for acute renal colic, they are associated with adverse events (AEs). As cyclooxygenase-2 selective NSAIDs may provide a safer alternative, we compared the efficacy and safety of parecoxib versus an nsNSAID in subjects with acute renal colic. MATERIALS AND METHODS: Phase IV., multicenter, double-blind, noninferiority, active-controlled study: 338 subjects with acute renal colic were randomized to parecoxib 40 mg i.v. plus placebo (n = 174) or ketoprofen 100 mg IV plus placebo (n = 164). 338 subjects with acute renal colic were randomized to parecoxib 40 mg IV (n = 174) or ketoprofen 100 mg IV(n = 164) plus placebo. Subjects were evaluated 15, 30, 45, 60, 90 and 120 minutes after treatment start and 24 hours after discharge. Primary endpoint was the mean pain intensity difference (PID) at 30 minutes by visual analog scale (VAS) (per-protocol population). An ANCOVA model was used with treatment group, country, and baseline score as covariates. Non-inferiority of parecoxib to ketoprofen was declared if the lower bound of the 95% confidence interval (CI) for the difference between the two groups excluded the pre-established margin of 10 mm for the primary endpoint. RESULTS: Baseline demographics were similar. The mean (SD) mPID30 min was 33.84 (24.61) and 35.16 (26.01) for parecoxib and ketoprofen, respectively. For treatment difference (parecoxib-ketoprofen) the lower bound of the 95% CI was 6.53. The mean change from baseline in VAS 30 minutes after study medication was ~43 mm; AEs were comparable between treatments. CONCLUSIONS: Parecoxib is as effective as ketoprofen in the treatment of pain due to acute renal colic, is well tolerated, and has a comparable safety profile
