This study evaluates the wound-healing process in horses following the application of two treatment modalities: bacterial cellulose hydrogel with alginate (BCAW) and frog skin (FSW) dressings on experimentally induced skin wounds. Throughout the experiment, no clinical abnormalities were noted in the horses, although initial wound assessments indicated edema and sensitivity. Local hemorrhage was observed in some cases on Day 0, with granulation tissue formation evident by Day 14. Epithelialization began around Day 14 but did not reach complete healing in any group by Day 28. The analysis showed no significant differences in skin wound area or wound contraction rates among the treatment groups compared to control wounds (CWs) over the evaluation periods. Histopathological evaluations also indicated no significant differences in inflammatory responses or healing markers, such as fibroblast proliferation and neovascularization in skin wounds across groups. Despite expectations based on prior research in other species, the treatments with BCAW and FSW did not demonstrate substantial pro-healing effects in horses with induced skin wounds. These findings underscore the complexity of equine wound healing and suggest further investigation is needed to optimize treatment strategies in this species and enhance the translational potential for human clinical applications.

We evaluated the macroscopic and histopathological aspects of skin healing by secondary intention in equine wounds, surgically induced and topically treated with bacterial cellulose hydrogel with alginate (BCAG) or frog skin (FSG), compared with ringer lactate (CG). Three wounds were created on each side of the lumbar region, one side for gross evaluation with photos and measurement of the area and contraction rate and the other for histopathological evaluation, with the sides selected randomly, in 5 horses. All wounds received daily treatment, and clinical and histopathological evaluations were conducted on postoperative days 0, 3, 7, 14, 21, and 28. Although no statistical differences were observed, the BCAG presented a reduced wound area and a high wound contraction percentage on days 14 and 21. At 28 days, the average contraction rates were 96.08%, 92.87%, and 88.6% for the CG, BCAG, and FSG, respectively. Although there was no statistical difference between the groups in wound healing in this study in horses, in clinical evaluations an early start of filling the area of the wounds treated with frog skin was observed, and on D14 and D21, a smaller area and higher contraction rate were observed in BCAG, which can be attributed to more efficient re-epithelialization and fibroblast proliferation.

Male reproductive tract disorders (MRTDs) are common in equids and may represent a significant proportion of the caseload of equine practitioners. Herein, we determined the frequency, clinico-pathological findings, and therapeutics of MRTDs in equids from a 9-year survey of the clinical records of a Veterinary Teaching Hospital in Midwestern Brazil. During this period, 87 affected equids presented 100 MRTDs distributed in 17 different diagnoses. Forty-three (49.4%) equids presented MRTDs affecting the glans penis or preputial skin fold. Testicles, scrotum, and spermatic cords disorders were diagnosed in 32 (36.8%) horses. Of the remaining 12 (13.8%) horses, six presented two different MRTDs on two distinct anatomical areas, and five animals exhibited the same disease, affecting two different anatomical locations. Only one horse presented three distinct MRTDs on two anatomical regions. Habronemiasis was the most frequent MRTD detected in 26% of the diagnoses, followed by miscellaneous wounds (14%), cryptorchidism (13%), inguinal hernia (13%), funiculitis (9%), paraphimosis (6%), squamous cell carcinoma (5%), urethrolithiasis (3%), preputial abscesses, and orchitis (2% each). Phimosis, ulcerative posthitis, epididymitis, hydrocele, papillomatosis, teratoma, and testicular torsion accounted for 1% each. Sixty-three (72.5%) equids received hospital discharge, 18 (20.6%) were humanely euthanized, and six (6.9%) died. This study detected the most relevant MRTDs that affected over 7.5% in a survey of 1,154 equids referred for hospital care. Our finding highlights that MRTDs may be debilitating and life-threatening conditions, and they can potentially impact the reproduction of equids in the region. This knowledge may support equine practitioners in elaborating proper sanitary and management protocols to prevent and reduce the incidence of most MRTDs recorded, improving equid production and welfare.

Tendon rupture is an uncommon cause of lameness in small ruminants. This report aimed to present a successful common calcaneal tendon (CCT) tenorrhaphy in a Dorper lamb after rupture during a tail docking procedure. The lamb presented a 3.5 cm linear open wound over CCT. During surgery, an incision was made over the skin on the caudolateral aspect of the distal tibia over CCT. The tendon stumps were isolated using haemostats, repair was performed via a locking‐loop suture pattern using non‐absorbable suture material. Postoperative limb immobilisation was conducted using a full‐limb compressive bandage and a modified Schroeder–Thomas splint, and follow‐up continued for 4 weeks. Ten months postsurgery, a fibrous callus was evident and the lamb exhibited no lameness. In this report, CCT tenorrhaphy using non‐absorbable suture in a locking‐loop pattern was a successful approach. Limb immobilisation in extension and specific physiotherapy are important methods to fasten the patient's rehabilitation.

This paper aimed to report a successful forelimb amputation and long‐term follow‐up in a White Dorper ram. An 8‐month‐old 45.5 kg White Dorper ram was found standing on the exposed metacarpal bone of the right forelimb. Detailed clinical examination and radiographic evaluation confirmed metacarpophalangeal avulsion. Limb amputation was performed by radiocarpal disarticulation. Postoperative complications included wound infection and dehiscence. Fifteen days post‐surgery, the necrotic accessory carpal bone was retrieved during wound cleaning. After this, the stump healed rapidly by secondary intention within 30 days. During this recovery time, the ram showed good adaptation to walking on three legs, and the owner gave up buying the prosthesis. The ram returned to the flock fully adapted 45 days after surgery. We emphasize that documenting more limb amputations in livestock is critical to obtain conclusions about the prognosis, life expectancy and expected quality of life.
