Abstrakt: Wounds localized on the distal limbs in horses are difficulty healing. No studies have been conducted to evaluate homologous platelet-rich plasma (PRP) in horses. The aim of this study was to evaluate the effect upon applying autologous PRP, homologous PRP, and autologous PRP gel on the wound healing process of wounds on the distal limb of horses. To study a possible correlation between the platelet count and wound healing time, four skin wounds of 4 cm 2 were surgically created on the dorsolateral aspect of the third metacarpus in eight healthy adult horses. Each skin wound was randomly treated according to the established treatment groups (G): GI, treated with autologous PRP injection on the wound edges; GII treated topically with autologous PRP gel; and GIII homologous PRP injection on the wound edges and control group treated with saline solution injected on the wound edges. The animals were monitored every fifteen days throughout the wound healing process. The wound size was determined using a tape measure. Skin biopsies were obtained on the 15th and 30th day after the first PRP treatment. Autologous PRP gel treatment reduced the healing time in 15 days compared to the wounds of the control group. Histologically, GII presented a higher frequency of mild inflammation and mild to moderate neovascularization of biopsies 1 and 2. Platelet-rich plasma in gel form showed the best result on wound healing of the distal limb of horses in both clinical and histopathological evaluations. The homologous PRP is recommended for the recovery of animals with compromised hemodynamic conditions.
