The vascular arrangement in the skin of some tropical breeds of cattle and of temperate cattle in a tropical environment is reported. Four vascular plexuses were observed in the skin of all breeds of cattle studied. The first horizontal plexus was observed between the subcutaneous and reticular layers, the second at mid-reticular layer level, and the third and most prominent at the level of the hair papillae and sweat glands. The fourth plexus arose as a branch from the third, extended upwards to the sebaceous gland and upper hair follicle region and gave off twigs to the dermo-epidermal junction. The sweat glands and hair follicles were profusely supplied with blood vessels. The branches of the fourth plexus extended closer to the epidermis in the tropical breeds than in the Friesian.
报告了一些热带品种牛以及处于热带环境中的温带品种牛皮肤中的血管分布情况。在所研究的所有品种牛的皮肤中均观察到四个血管丛。第一个水平血管丛位于皮下层和网状层之间，第二个在网状层中部水平，第三个也是最显著的一个位于毛乳头和汗腺水平。第四个血管丛作为第三个血管丛的分支出现，向上延伸至皮脂腺和毛囊上部区域，并向真皮 - 表皮交界处发出小分支。汗腺和毛囊有丰富的血管供应。与弗里斯兰牛相比，热带品种牛中第四个血管丛的分支向表皮延伸得更近。
