Epidemiological studies confirmed that SBV infection could have severe negative impacts on animal welfare and productivity in affected flocks of sheep (Ovis aries), but there was a lack of specific research on the impacts of infection on recorded reproductive performance, animal welfare, financial performance, and farmers’ emotional well-being in some of the first affected early lambing flocks in South West England in 2012 / 2013.\u0000Objectives\u0000This mixed methods veterinary practice-based descriptive study aimed to describe the clinical signs observed by sheep farmers in the region experiencing outbreaks of disease due to SBV for the first time; to evaluate physical records (quantitative data) on reproductive performance in early lambing flocks prior to and during the affected 2012 / 2013 production year; and to gauge farmers’ perceptions (qualitative interview data and quantitative severity scores) of the impacts of SBV infection on animal welfare, financial performance, and their emotional well-being, and risks of future outbreaks of disease and preventive strategies including SBV vaccination.\u0000Evidentiary value\u0000This mixed-methods descriptive study reported farmers’ detailed experiences, and recorded and perceived impacts, of SBV infection in six pedigree and purebred flocks in South West England, lambing early between November 2012 and January 2013. Previous surveys were larger than the current study and assessed the impacts of SBV at farm rather than flock level and on a more diverse range of British sheep farms lambing over extended periods; impacts were compared between three categories of farms based on laboratory confirmation or farmers’ suspicions of infection i.e. ‘SBV confirmed’, ‘SBV suspected’ and ‘SBV not suspected’. This study was able to capture and compare the reproductive performance of these flocks in the SBV affected production year in 2012 / 2013 with up to three previous unaffected years; it found variable negative effects of SBV not only on ewe and lambs losses, stillbirths and abortions, levels of dystocia and need for variable levels of assistance to deliver lambs, but also on overall flock reproductive performance, barren rate, lambing percentage and lamb rearing percentage. The qualitative elements of the study enabled new insights into the variable effects of SBV infection in flocks on ewes and lambs and on farmers’ perceptions of the impacts on animal welfare, flock financial performance and their own emotional well-being. The findings suggest previous surveys may not have fully captured the impacts of SBV infection in high value pedigree and purebred early lambing flocks infected for the first time during the second wave of virus circulation and peak midge vector activity in the southwest region in summer and autumn 2012.

(2015) evaluated postoperative recovery in 206 dogs following surgical castration using a scrotal incision in comparison to 231 dogs using a pre-scrotal approach. Complications observed in order of frequency, included: incisional swelling; haemorrhage; pain; and self-trauma, however, apart from self-trauma, complications were not influenced by incision location. Dogs castrated using a scrotal approach had reduced odds of self-trauma (OR: 0.51, P = 0.04, 95% CI 0.27–0.97). Moreover, mean duration of surgery was faster for the scrotal versus the pre-scrotal approach (3.6 minutes, P<0.01, 95% CI 3.38–3.82 versus 5.1 minutes, 95% CI 4.86–5.41).\u0000Miller et al. (2018) evaluated complication rates following open or closed castration using a scrotal approach in 400 shelter dogs under the age of 6 months. Complications involving intra-operative bleeding were not observed, while marginal rates of post-operative events were reported, including peri-incisional dermatitis (2.3%), skin bruising (1.0%), and swelling (0.3%). No self-trauma or rescue analgesia was recorded. In comparing surgical time, the mean duration was 1 minute ± 0.2 minutes in dogs undergoing scrotal surgery, in comparison to canine patients undergoing the same procedure using a pre-scrotal approach, where the mean duration was 3.5 minutes ± 0.4 minutes.\u0000Conclusion\u0000The outcomes of these two studies imply that a scrotal incisional approach in canine castration is at least no worse in the first 24 hours than a traditional pre-scrotal approach and may also reduce mean duration of surgery.
