Effect of Frequent Ejaculation on Live Weight and Sperm Characteristics in Norduz Lambs

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.

Some Factors Affecting Milk Production and Post Partum Body Weight of Fat-Tailed Norduz Ewes in Turkey

Abstract Bingöl, M., Aygün, T., Gökdal, Ö. and Yilmaz, A. 2005. Some factors affecting milk production and post partum body weight of fat-tailed Norduz ewes in Turkey. J. Appl. Anim. Res., 27: 125–127. This study was conducted to determine some traits of milk production and post partum body weights of Norduz ewes in Van-Norduz provinces. Overall means for lactation period, lactation milk production and postpartum body weight were 174 days, 178 liters and 58 kg, respectively. Only post partum body weight was affected (P<0.05) by age of ewe or parturition type. The Norduz ewe has been recommended for milk production.
