Abstract
Bingöl, M., Yilmaz, A., Cengiz, F. and Kum, D. 2006. Effect of frequent ejaculation on live weight and sperm characteristics in Norduz lambs. J. Appl. Anim. Res., 30: 141–144. To determine the effects of frequent ejaculation on live weight and sperm characteristics, 12 Norduz rams (17 mo) were divided into three groups. The semen samples of the second and third group rams were collected 3 and 5 times per day, respectively, while no semen was collected from the first group. The sperm motility, semen viscosity and mass motility were marginally better in rams of third group (P<0.05). In both groups semen volume decreased over the days and ejaculate number on the same day. Other parameters were either unaffected or did not follow any definite pattern. It is concluded that live weight of rams and semen characteristics were not affected by taking 3–5 ejaculates in a day in Norduz rams.
