[ Objective] The study was to explore whether the body size, sexual behavior of male donkey had certain correlation with reproductive traits. [ Method] The data of body weight, body size and sexual behavior of male donkey during production were collected, combining with the semen quality data of ejaculation volume, density, motility and frozen-thawed semen motility were conducted the statistical analysis. [ Results] （ 1 ） Single ejaculation volume had a positive correlation with body height （r = 0. 423, P = 0. 044） and penis circumference （r = 0. 495, P = 0. 043 ） , and total number of sperm per ejaculate had a positiw： correlation with body weight （r = 0. 444, P = 0. 036） and scrotal circumference （r = 0. 520, P = 0. 039） ; （2） Ejaculation volume was negatively correlated with mount times （r = -0. 159, P = 0. 035） and erection time （r = -0. 181, P = 0. 023）, semen density was negatively correlated with mating time （r = - 0.211, P = 0.004）, and total sperm count was negatively correlated with erection time （r = - 0. 159 , P = 0. 047）. [Condusion ] The quality of semen had a certain correlation with body size, body weight and sexual behavior.
