All cattle were female and mostly young (13 months, median age; range, 9 – 92 months). The median lameness score was 3/5 (range 1 – 5/5), and all cattle could stand.

Simple fractures were the most common and occurred in 25 cattle; one heifer had bilateral simple acetabular fractures with ischial involvement. Fractures with 1–2 additional fragments occurred in four cattle, and seven animals had comminuted fractures. Treatment consisted of stall rest for 3 months.

Dental radiographs of 248 dogs weighing less than 15 kg, examined over a three-year period, were included in this study. Statistical analyses were performed to investigate the associations between the examined variables and TR. The most common type of resorption was external replacement resorption (ERR), followed by external inflammatory resorption (EIR). Significant associations were found among age, number of missing teeth, and total TR (<em>p</em> < 0.01). In addition, the prevalence of ERR and EIR increased with age (<em>p</em> < 0.01). The rate of TR was significantly higher in premolars than in incisors, canines, and molars (<em>p</em> < 0.001). Maltese dogs showed a significantly higher prevalence of TR (<em>p</em> < 0.05), particularly ERR (<em>p</em> < 0.05), than other breeds. The TR rate increased significantly in dogs aged 9–11 years, 12–15 years, and over 15 years.

Horses with NSII need surgical intervention, while idiopathic peritonitis cases can be successfully treated with antimicrobials. A correct diagnosis is thus crucial, but because the two diseases overlap in clinicopathological features, differentiation is difficult in clinical practice. MicroRNAs (miRNAs) are non-coding RNAs that exhibit measurable changes in abundance in tissues and circulation during disease. This study aimed to explore differences in plasma miRNA abundance between patients with NSII and IP. Plasma samples were collected from 43 horses, consisting of 21 with NSII and 22 with IP. A subset (n = 12) was submitted for deep small RNA sequencing to identify miRNAs differing between the groups. Next, a panel of nine miRNAs (two were potential normalizers) were selected for evaluation and confirmation by reverse transcription quantitative real-time PCR (RT-qPCR). Small RNA sequencing detected 628 miRNAs in the blood samples, but no miRNAs were differentially abundant between the disease groups. This finding was confirmed by qPCR. In agreement with previous studies, the top abundant miRNAs in both groups included Eca-Mir-122–5p and Eca-Mir-486–5p, as well as Eca-Mir-223–3p, which has previously been associated with inflammation. Target prediction for the most abundant miRNAs additionally predicted targets in inflammatory pathways. Evaluation of clinicopathological parameters revealed differences between the groups in two measures (white blood cell count and blood neutrophil count), which aligns with findings from previous studies.

Consequently, through expert consultation, this study aimed to synthesise knowledge regarding domesticated equine emotional state, specifically methods to induce and measure positive affective states, which could be of significant benefit to equine welfare across sectors. A Delphi consultation of experts in the field of equine behaviour, welfare and affective state was undertaken to derive consensus agreement on definitions used when considering positive affective state in equines and methods suitable for inducing and measuring these states within experimental investigations. Ninety-three international experts participated in a robust three-round Delphi consultation with data gathered analysed qualitatively (thematic analysis) and quantitatively (ranking data, consensus benchmarks and Content Validity Index (CVI) / Content Validity Ratio (CVR) analyses). Retention rates were high (78 %), and consensus (minimum 70 % agreement) was reached within Round three of the consultation. Nineteen methods for inducing positive affect reached consensus (provision of high value food, an affiliative companion and a substrate to roll in where the highest ranked), and twelve behavioural (assessment of body language, facial actions and horse-horse interactions were ranked highest) and three physiological (evaluation of heart rate, heart rate variability and respiratory rate) variables for measuring positive affect also reached consensus. This consultation highlights several important considerations surrounding the induction and measurement of positive affective state in equines, including consideration of the individual’s personality and individual preference within any measures of affective state. We therefore recommend that establishing individual preference should be a prerequisite of research into positive affective states.
