摘要 [ 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.
