Popis:	Umesiobi, D.O. 2006. Effect of oral administration of Clomiphene citrate on sperm viability and fertility of boar semen. J. Appl. Anin. Res., 30: 167–170. In order to improve semen characteristics of boars with poor quality semen, 24 (2.0 years old) Large White boars and 120 cycling non-lactating Large White sows (aged 2.5 years) were used in this study. Two groups of eight boars each were randomly administered with oral doses of either 50 mg or 100 mg Clomiphene citrate daily for 5 days and a control group of 8 boars was administered with normal saline for the same period. Semen characteristics were examined twice a week for 16 weeks. Semen from each boar was randomly inseminated into five sows following sperm viability tests. It was observed that total semen volume, sperm motility, per cent live sperm, total sperm/ejaculate, sperm with normal apical ridge and serum testosterone levels improved with increasing levels of Clomiphene citrate. Sows inseminated with semen from such boars resulted in ...
