Abstract
The effect of different intensities of semen collection on semen characteristics, cations and fructose concentrations of the seminal plasma in West African dwarf bucks was studied. Twelve clinically healthy and matured bucks weighing between 25.6 – 35.7 kg were randomly allocated to four treatment groups in a completely randomized design (CRD). Semen quality (expressed as progressive motility and percentage of morphologically normal/life sperm cells) and sperm quantity (expressed as sperm concentration and semen volume), the cations (sodium, potassium, calcium, and magnesium) and fructose concentrations in the seminal plasma were the parameters evaluated in each buck. The highest sperm motility and percentage live sperm cells were observed when semen was ejaculated once per week. As compared with twice per week, three times per week and four times per week, the once a week ejaculations in semen concentration and volume were highest. The cations and fructose levels of the seminal plasma were highest at the once per week ejaculations. The results of this study indicate that once per week semen ejaculation enhances the fertility of West African dwarf bucks.
