Based on results of this study, it can be concluded that although Caspian miniature horses and donkeys have same body size, it seems that due to genetic differences, considerable heterogeneity was observed in second-intention wound healing between them.

Abstract

In this study, second-intention healing of limb wounds was studied in donkeys and Caspian miniature horses. Full-thickness, rectangular (2 × 3cm) skin wounds were created on the lateral aspect of left metacarpi of four donkeys and four Caspian horses.

Wound healing process was compared between limb wounds of donkeys and Caspian horses by clinical and geometrical assessments, over a 4-week period. At days 0, 3, 7, 10, 14, 17, 21, 24, and 28, digital photographs were taken of all wounds. The area of epithelialization and granulation tissue was measured for each wound using sigma scan software.

Percentages of wound contraction, epithelialization, and healing were calculated for each wound. The clinical and geometrical evaluation revealed that there were significant differences in second-intention wound healing patterns between donkeys and Caspian horses. The donkeys limb wound healed much faster and in better condition than the limb wound of the Caspian horses.

Based on results of this study, it can be concluded that although Caspian miniature horses and donkeys have same body size, it seems that due to genetic differences, considerable heterogeneity was observed in second-intention wound healing between them.
